Daily threat of severe storms to extend into Memorial Day weekend
While no major outbreaks of severe weather are anticipated through Memorial Day, localized severe weather can still occur in various parts of the nation on a daily basis. AccuWeather has the details on where and when people should pay close attention to potentially dangerous weather conditions. Storms to rattle part of interior Northeast Wednesday On the back side of a developing nor'easter that will bring drenching rain to New England and parts of the mid-Atlantic and central Appalachians, thunderstorms will erupt into Wednesday evening. The greatest risk for storms with high winds, hail and torrential downpours into Wednesday evening will be from central Ohio to southwestern Pennsylvania and northwestern West Virginia. Farther to the north and east in the Northeast, the air will be too cool and cloudy to support thunderstorms. Southeast storms to settle toward Florida into Friday The tail end of the front that produced more than a thousand incidents of severe weather, including dozens of tornadoes, since late last week, will push offshore of much of the Southeast by Wednesday night. However, before it does, thunderstorms will be a bit feisty in eastern North Carolina, as well as northern Florida and southern Georgia, on west to southeastern Louisiana. While there could be a couple of tornadoes in either zone, the main threat will be from high wind gusts, hail and flooding the app? Unlock AccuWeather Alerts™ with Premium+ "As the tail end of that same front creeps southward over the Florida Peninsula, combined with a sea breeze from the Atlantic, a few robust thunderstorms can occur from east-central Florida Thursday to southeastern Florida on Friday," AccuWeather Senior Meteorologist Dave Dombek said, "Many Florida storms tend to pack a punch, but these could be locally severe with strong wind gusts, in addition to the usual, frequent lightning strikes and flooding downpours." Occasionally, potent Florida thunderstorms can produce a tornado or waterspout. The storms will tend to form near the beaches during the morning, then drift inland during the midday and afternoon. "It's possible a storm may wander close to the Orlando theme parks," Dombek said. More severe storms anticipated for parts of Plains states Farther west, severe weather is forecast on a daily basis across portions of the Plains states from Thursday to Sunday. The main threats from storms over the central and southern Plains from Thursday to Friday will be due to large hail and damaging wind gusts. On Thursday afternoon and night, the storms will tend to focus mostly from central Texas, northward to much of southern Oklahoma. Cities that may experience severe weather Thursday evening include Dallas, San Antonio, Texas, as well as Lawton, Oklahoma. From late Friday to Friday night, the area most likely to experience severe thunderstorms will shift northwestward and include areas from northwest Texas to western and central Nebraska. Cities that could experience severe weather Friday evening include Amarillo, Texas; Wichita and Topeka, Kansas; North Platte, Nebraska; and Oklahoma City. During the weekend, the main risk of severe weather will begin to expand and then shift slowly eastward over the South Central states. On Saturday, the likelihood of at least locally severe thunderstorms will extend from the western portions of Texas, Oklahoma and Kansas, as well as eastern Colorado to southeastern Missouri and northeastern Arkansas. The risk of tornadoes will increase Saturday, as some of the storms are expected to pack damaging hail and high winds. On Sunday, the severe weather threat zone will begin to push eastward more directly and will be centered on the lower Mississippi Valley. The severe weather risk will extend from north-central Texas to south-central Kansas, eastward to parts of middle Tennessee and northern Alabama. Due to the repetitive nature of some of the thunderstorm downpours, the risk of flash flooding will increase daily from parts of the southern Plains to the lower part of the Mississippi Valley with the Ozark Mountains-a popular vacation and camping destination. Those outdoors should use extreme caution as storms brew due to the risk of lightning strikes. Campers should avoid setting up along small streams that could be prone to flash flooding. A downpour less than a mile upstream could produce a wall of water that quickly inundates low-lying areas. On Memorial Day, the risk of severe thunderstorms will focus over the Southeastern states from near the lower part of the Mississippi River to Georgia and the Carolinas. The storms could directly affect outdoor activities Monday in cities such as New Orleans, Atlanta and Charlotte. Want next-level safety, ad-free?

Slow-moving storm could lock in rain, cool air for Northeast
Storms have moved steadily across the country during much of this spring. However, AccuWeather meteorologists say there are signs of an atmospheric traffic jam setting up that can have a profound impact on weather forecasts, including the northeastern United States. A round of thunderstorms can be locally severe from Thursday to Friday with the potential for high winds, hail, flash flooding and a few tornadoes in the Northeast. Instead of the front pressing steadily offshore this weekend, it will slow and stall near the Appalachians. That will set the stage for clouds, areas of rain and embedded thunderstorms over a large part of the Northeast, part of the Midwest and the Southeast. Many areas are likely to experience a thorough soaking, and there is the potential for an inch or more of rain in some locations. "After Saturday, there is a fork in the road in terms of what that storm may do next and has to do with where and when a storm at the jet stream level of the atmosphere forms," AccuWeather Senior Meteorologist Dave Dombek the app? Unlock AccuWeather Alerts™ with Premium+ It could pick up forward speed and dry air will chase clouds and rain offshore over the Atlantic. This scenario would allow dry and chilly to settle in on Sunday with the risk of frost over the interior of the Northeast Sunday night. In the second possible scenario, a storm may form in the jet stream level of the atmosphere in the Eastern states. Depending on where that storm forms, it could cause clouds, showers and spotty thunderstorms with chilly air to linger Sunday and perhaps into next week. The unsettled zone may be in the Ohio Valley and Northeast or it may congregate along the southern Atlantic coast. "Forecasting exactly where a closed low (jet stream-level storm) will form multiple days out is one of the most challenging aspects of the weather," Dombek said, "But this part of the spring to the early summer is one of the favored times of the year to see it occur." A lack of weather data from high levels in the atmosphere as opposed to the plethora of ground-level reporting sites issuing weather data may be a contributor. Weather balloons that carry instruments to measure temperature, humidity, wind and pressure help to fill some of that gap. That data is then fed into various computer models, which are the state-of-the-art tools meteorologists utilize. If the storm stalls in a specific spot, it could funnel a corridor of moisture from the Gulf and the Atlantic to across a portion of the Southeast coast to the mid-Atlantic next week. Such a rain event might be welcome in terms of brush fire relief, but could also spoil days of outdoor activities and possibly trigger flash flooding. Want next-level safety, ad-free?

Texas, Oklahoma among states at risk for flooding into next week
More rounds of rain through early May could trigger flooding across parts of the southern Plains already drenched by recent storms. Rainfall will also occur in some locations that need moisture due to ongoing drought, AccuWeather meteorologists say. Parts of Oklahoma have picked up as much as 5 inches of rain since Monday, while 1-2 inches have fallen across portions of northern Texas through early Wednesday. Short-term rain, flooding risk As the first round of rain continues, up to a few inches of additional rain can fall across portions of north-central and northeastern Texas, southeastern Oklahoma, and parts of southwestern Arkansas and northeastern Louisiana. Where inches of rain have already saturated the soil, the most significant risk of flash flooding is in low-lying areas and small streams as well as flooding on Red River tributaries. While the rain is forecast to retreat to the southeast Thursday, another cluster of downpours and severe thunderstorms will drop southeastward across the southern Plains from Thursday night to Friday. This batch of thunderstorms can bring rain to areas largely missed by downpours this week. However, more rain will fall on saturated soil in parts of Oklahoma and Texas, which can bring a new surge of high water to area streams and secondary rivers. After a quiet weekend without downpours and thunderstorms, the atmosphere will reload farther west by early next week. Long-term rain, flooding risk "The troublemaker will be a large storm at the jet stream level of the atmosphere over the Southwest states," AccuWeather Senior Meteorologist Dave Dombek said, "These upper-level storms are very challenging to be precise with several days in advance."Have the app?

(Image credit: Theo Stein/NOAA) Based on the latest available information, AccuWeather meteorologists believe that a large storm at the jet stream level of the atmosphere will set up over the Southwest and tap moisture from the Gulf. The result will be an uptick in showers and thunderstorms from Arizona to New Mexico, Colorado and the western portions of the southern Plains by early next week. The downpours may linger over the same zone for days or progress eastward over the southern Plains. Should the moist zone stall, beneficial rain in drought areas of the High Plains may evolve into a flooding event. If the moist corridor shifts farther east, it could bring another round of flooding rainfall to areas already hit hard by flooding this week. Where rainfall from this week's events and next week's events overlap, cumulative totals could top 10 inches, which is the equivalent of two to three months' worth of rain in some locations.

Late-week Northeast storm to pack rain, mountain snow and coastal flooding
After delivering brief showers and gusty thunderstorms to hard-hit flood areas in the Midwest, a storm will swing toward the Atlantic coast late this week and cause travel problems related to cold rain, high-elevation snow and raw winds near the coast that will raise tide levels, AccuWeather meteorologists advise. Following a weaker system that is forecast to bring showers of rain and wet snow to the region on Thursday, the late-week storm will have significant impacts more typical for late February or early March rather than the middle of April. Showers of rain and wet snow will precede the main storm on Thursday. Soaking rain, travel delays from the storm Rain from the main storm will spread over the mid-Atlantic region, from the Carolinas to West Virginia, Virginia and Maryland on Friday, then slowly pivot over the rest of the mid-Atlantic and much of New England during Friday night and Saturday. "It looks like a general 1-2 inches of rain will fall on much of the Northeast with local amounts to near 3 inches," AccuWeather Senior Meteorologist Dave Dombek said. "The heaviest amounts will extend roughly from Virginia to southern New England." Enough rain can pour down to cause urban flooding in some neighborhoods. The combination of rain, ponding and poor visibility can lead to hazardous conditions on the highways. Drenching rain, fog and low clouds and even thunderstorm activity may trigger airline delays at the the app? Unlock AccuWeather Alerts™ with Premium+ The rain will be beneficial from a spring wildfire and dry brush standpoint. It will help with greenup and thoroughly soak the remaining dry brush in the region. Even though rain has been plentiful in recent weeks and months, there is a long-term deficit that had its roots in last summer and autumn. Coastal flooding risk The slow-moving storm will create an extended period of onshore winds from the upper mid-Atlantic to New England. "In areas from near New Jersey and New York City to central New England and Boston, east to northeast breezes will last around 48 hours or so mainly from Thursday night to Saturday afternoon," Dombek said. "The duration of the onshore wind and the upcoming full moon (April 12) close to the same time will lead to coastal flooding at times of high tide." Tides are expected to run 1-3 feet above the already elevated astronomical levels. Few coastal flooding events have occurred since the winter, so coastal flooding can potentially sneak up on some communities. Snow to fall, accumulate in higher elevations Much like an early-March storm, this one will bring some snow to the region. However, most of that will be confined to the ridges, plateaus and peaks from the southern Appalachians to northern New England. "It looks like at around 1,800 feet or so, wet snow will mix in with the rain soon after it begins on Friday and Friday night," Dombek said. "But depending on the storm intensity and track, beginning somewhere from 2,500 to 3,000 feet, there can be a few inches to a heavy accumulation of wet snow." Typically, it has to snow hard during the day to accumulate on roads during the middle of April. Even light to moderate snow that falls at night or first thing in the morning can temporarily bring slippery conditions. This snow accumulation risk will extend from the Smoky Mountains of western North Carolina and eastern Tennessee to the Alleghenies, Poconos, Catskills, Berkshires, Adirondacks, Greens and Whites. While most major roads are at elevations below the critical elevation for this storm, some high-elevation sections can become slushy and snow-covered. Want next-level safety, ad-free?

Late-week storm with heavy rain, mountain snow to eye parts of eastern US
As an unseasonably cold weather pattern continues to evolve in the Northeast this week, indications point toward a storm forming and bringing drenching rain, with some snow at high elevations, by the weekend, AccuWeather meteorologists say. The storm will follow snow showers over the interior Northeast into Tuesday, along with a small zone of rain and wet snow expected across the Ohio Valley, Great Lakes, and central Appalachian at midweek. The midweek storm will be small and moisture-starved but may produce some accumulating wet snow in parts of the Upper Midwest. The late-week storm will swing across flood-ravaged areas of the mid-Mississippi and Tennessee valleys on Thursday with little precipitation. However, as it drifts east of the Appalachians, it will gain strength and draw moisture from both the Gulf and the Atlantic. The storm may produce 1-3 inches of rain, with locally higher amounts possible, in some areas from the Carolinas to the mid-Atlantic and New England. With downpours embedded in the steadier rain, localized urban flooding could occur. "Right now, it looks like while some wet snow can mix in at intermediate elevations of the Appalachians, locations of 2,500 feet or higher could experience several inches of snow," AccuWeather Senior Meteorologist Brett Anderson said of the late-week the app? Unlock AccuWeather Alerts™ with Premium+ As the weekend approaches in Washington, D.C., Philadelphia, New York City and Boston, rain may pose problems for travelers and those with outdoor plans. Fog, downpours and thunderstorms could lead to airline delays, while the wet weather may spoil a day at the ballpark, a walk in the park or a round of golf. Aside from urban ponding, the rain could be beneficial, helping to ease long-term dryness and developing drought conditions that have persisted in parts of the East since well back into the winter. When combined with the typical spring greenup underway, the soaking rain should bring an end to wildfire concerns in the short term. However, in areas that miss out on the rain, wildfire risk may persist. One area where wildfires have been a problem this spring is Florida. March to April is typically a very dry period in the region, as thunderstorms fueled by warmth and high humidity do not typically ramp up significantly until May. Rainfall in much of Central and South Florida has been about 50% of the historical average since the start of the year, AccuWeather Senior Meteorologist Dave Dombek said. "Saturday could be a troublesome day for the Florida Peninsula with warm, dry air and stiff breezes," Dombek stated. "This will be especially true where any landscape-drenching showers manage to avoid locations during the week." Want next-level safety, ad-free?
