Downpours to unleash flash flooding in Texas, Oklahoma and Arkansas
Inches of rain are forecast to pour down on a zone from central and eastern Texas to southeastern Oklahoma and western Arkansas in the coming days, which can trigger dangerous flash flooding. Downpours will be strewn across the Interstate 10 and 20 corridors of the southern United States from New Mexico and Texas to Florida, Georgia and the Carolinas into midweek. In some instances, the heavy rain will be associated with gusty and severe thunderstorms. Some of the most intense thunderstorms from large complexes will focus on parts of Texas into Tuesday night, with some areas potentially blasted by more than one severe storm with high winds, hail and flash flooding in 24 hours. Should a large complex of thunderstorms reach its peak intensity, a long-lived high wind event that tracks for hundreds of miles could unfold. The weather community refers to such a potentially large, damaging thunderstorm complex as a derecho. At this time, AccuWeather meteorologists believe that a derecho is unlikely, but some communities can face damaging weather as storms become intense for a brief time and lead to regional power the app? Unlock AccuWeather Alerts™ with Premium+ A storm swinging out from northern Mexico will track across the South Central states from Wednesday to Friday, setting the stage for thunderstorms to erupt in a very moist environment created by the Gulf. This setup will unleash the tremendous amounts of moisture in the atmosphere in the form of torrential downpours where up to a few inches of rain can pour down in a few hours or less. This alone can trigger rapid flooding of city streets, turn dry washes into raging torrents and lead to rapid rises on some streams and rivers in the region from central Texas to western Arkansas, including southeastern Oklahoma and perhaps northwestern Louisiana. "Some of the heaviest rain and perhaps a concentration of flash flooding is likely to occur along the I-35 corridor of Texas and southern Oklahoma and includes the major cities of Dallas, San Antonio and Austin, Texas," AccuWeather Senior Storm Warning Meteorologist Eddie Walker said. Where the downpours repeat over a number of days, 6-10 inches of rain could fall in localized areas, which can lead to flooding on a more regional basis. Much of the zone where the heaviest rain will fall is not in drought, as downpours since the early spring have replenished soil moisture and then some. There are some areas, mainly south and west of Austin, where drought is serious and any non-flooding rainfall would be welcomed. However, even in part of this zone of south-central Texas, too much rain can fall too fast and lead to dangerous flash flooding. "In Texas, many droughts end in floods," AccuWeather Chief On-Air Meteorologist Bernie Rayno said, "However, in this case, flash flooding won't discriminate between drought and saturated areas."

Severe weather threat increasing for South, Midwest and East next week
The first significant threat of severe weather for March will build across portions of the southern Plains and the lower Mississippi Valley on Tuesday before shifting toward the Appalachians, northeastern Gulf coast and southern Eastern Seaboard on Wednesday, AccuWeather meteorologists warn. The threat includes the potential for tornadoes. A storm currently over the northern Pacific Ocean is projected to push onshore in the northwestern United States this weekend and dive across the Rockies on Monday. The storm's next path will take it across the Southern states, where it will tap Gulf moisture. The combination of that moisture, building warmth and a strong jet stream will boost the risk of severe weather and likely some tornadoes. At this stage, numerous to widespread severe thunderstorms will likely occur on Tuesday over the south-central region and at least some severe thunderstorm activity on Wednesday from part of the Ohio Valley to the Southeast states. AccuWeather meteorologists will be watching the situation closely. "As we see it now, thunderstorms are likely to erupt rather quickly, strengthen and organize at midday on Tuesday," AccuWeather Senior Storm Warning Meteorologist Eddie Walker said. "This appears to be primarily a strong wind gust event, but there can still be a few tornadoes." Peak straight-line wind gusts in many of the storms will range between 65 and 75 mph, which is as high as hurricane intensity. The AccuWeather StormMax™ wind gust is currently rated at 90 mph. Sometimes, when thunderstorms erupt quickly and organize into a solid line, there may be fewer supercell thunderstorms. Individual supercell thunderstorms often produce the strongest tornadoes. Damaging hail and flash flooding are also a concern from the storms as storms move the app? Unlock AccuWeather Alerts™ with Premium+ As the storms approach and pass through the airport hubs, airline ground stops and flight delays will result. Motorists will encounter delays on the highways due to poor visibility from windswept rain and ponding during torrential downpours. Thunderstorms are projected to organize into a solid line, sometimes referred to as a squall line, during Tuesday night and Wednesday. "Since the center of the low pressure area, or storm, is likely to track northeastward into the Midwest, the threat of severe weather on Wednesday may extend from Ohio to Florida and Virginia along an advancing cold front," Walker said. Wind gusts are likely to remain the primary threat with gusts in the strongest storms between 65 and 75 mph. The AccuWeather Local StormMax™ wind gust for Wednesday's storms remains at 90 mph. The same storm system will have a cold and wet portion to deal with. "There will be snow on the backside of that storm on Tuesday from the Rockies to the Great Lakes," AccuWeather Senior Director of Forecasting Operations said. The warmest air of the year so far could have the snow cover in the northern tier primed for a rapid meltdown. "There may be flooding across the interior Northeast during Wednesday and Wednesday night, where rain pours down on top of the deep snow, especially in upstate New York, New Hampshire, Vermont, and Maine," DePodwin added. March often marks a significant upturn in severe weather, especially in the South Central and Southeast states where the combination of building warmth and moisture from the Gulf overlap. The pattern through much of March will continue to favor storms of similar nature traveling out from the Rockies and either toward the Great Lakes or the middle to southern East coast. "There is the potential for at least three more severe weather events in the next three weeks in the Central and Eastern states," AccuWeather Lead Long-Range Meteorologist Paul Pastelok said. "However, the scope, location and intensity of these will likely vary." Want next-level safety, ad-free?
