Weather Authority Impact Day issued for Tuesday's severe storm threat
HUNTSVILLE, Ala. (WHNT) — While isolated storms will be possible Sunday and Monday across the Tennessee Valley, a more potent storm system is forecast to track through the area Tuesday into Wednesday.
Ahead of a widespread threat of strong to severe storms, The Weather Authority has issued an Impact Day from Tuesday afternoon into early Wednesday morning.
Storms that can develop will be capable of producing damaging winds, large hail, frequent lightning, and tornadoes. Outside of storms, winds will also be on the stronger side. Gusts between 25 to 30 mph will be possible.
A potent storm system is forecast to move into the region, leading to a warm front passage. This warm front passage will allow for the increase of warm and moisture into the region.
The Tennessee Valley will also be placed in an area between the cold and warm fronts known as the 'warm sector'. This sector will have all the ingredients present to support the widespread coverage of strong to severe storms.
The Storm Prediction Center has the area for a 30% or greater chance of a severe storm to form within 25 miles of the area highlighted in orange.
Ahead of Tuesday's widespread strong to severe storm impact, multiple disturbances tracking through the area will support the chance of isolated thunderstorms.
The rain chance will not be widespread, and this period is not expected to be a complete washout. This being said, isolated strong to severe storms will be possible. If these storms can develop they will be capable of producing strong winds, heavy rain, and hail.

Hot weather makes a brief appearance this week across Maryland
After a comfortable start to the week, temperatures are on the rise again across central Maryland, setting the stage for what could be the hottest day of the year before a shift to a stormier, cooler pattern heading into the weekend. Tonight, skies will be partly cloudy with lower humidity settling in behind a weak frontal boundary. Overnight lows will drop into the 60s, offering a pleasant and seasonable night for much of the region. Wednesday brings a return to sunshine and summer-like warmth. With high pressure building overhead, skies will be mostly sunny and temperatures will climb into the upper 80s by the afternoon. Humidity levels will remain manageable, but the heat will be noticeable, especially during the peak of the day. Thursday will mark the beginning of a much more humid stretch, with dew points rising and the air turning sticky once again. Partly cloudy skies will dominate, and highs will soar into the low 90s, making it potentially the hottest day of the year so far in the Baltimore area. Heat indices could push into the mid-90s during the afternoon, especially in more urbanized locations. Friday will remain hot and humid, with highs near 90 degrees. While most of the day will stay dry, the added moisture and daytime heating could trigger a few scattered storms in the afternoon and evening. Any storms that do develop may produce gusty winds and brief heavy rainfall. The weather pattern becomes more unsettled over the weekend, with better chances for rain and thunderstorms both Saturday and Sunday. High temperatures on Saturday will reach near 80, with scattered showers and storms possible throughout the day. On Father's Day Sunday, expect highs in the upper 70s to near 80, with continued opportunities for showers and thunderstorms—especially during the afternoon and evening hours. While not a washout, outdoor plans may need to be flexible depending on the timing of storm development. The unsettled weather continues into Monday, as a frontal boundary stalls nearby. Expect mostly cloudy skies, periods of rain, and the potential for a few embedded thunderstorms. Highs will remain in the low 80s. By Tuesday, a lingering shower is still possible early in the day, but conditions should gradually improve with partial clearing expected by the afternoon. Highs will again top out in the low 80s. Looking ahead to Wednesday, drier air returns with sunshine and warm temperatures. Highs will be solidly in the 80s, providing a brief return to fair weather before the next system approaches later in the week.

Heat persists throughout Utah with above-average highs
SALT LAKE CITY () – Happy Tuesday, Utah! Above-average warmth has arrived and will stick around for the next several days. Today's temperatures are expected to warm up another couple of degrees, which translates to daytime highs in the low to mid-90s for most valleys, 80s for high terrain, and upper 90s to low 100s for the warmest spots. There won't be much cloud cover in the north to provide shade, but parts of eastern and southern Utah will see a mix of sun and clouds. We can't rule out a brief thunderstorm rolling into the southwest desert, including Price, St. George and Cedar City. The bottom line? Building heat with above-average temperatures statewide. Lingering moisture allows for the chance of storms through the midweek. With the potential of storms in the forecast, our flash flood threat remains elevated for a few popular recreation spots. Flash flooding will be 'Possible' for some outdoor recreation areas in slot canyons, dry washes, and other low-lying areas, including Capitol Reef, Grand Staircase, Natural Bridges, Lake Powell and Bryce Canyon. The threat isn't high, but it's worth keeping your eyes to the skies if you plan on being in those areas. A ridge of high pressure will continue to strengthen and eventually center over Utah, allowing for high heat during the work week. We won't see temperatures fluctuate much this week, so expect our daytime highs to remain about five to ten degrees above seasonal norms. By Wednesday, a trough will clip Northern Utah, and while we have very dry air at the surface, we have the chance to see storms develop, and strong outflow winds are expected in Northern Utah. As a result of the damaging wind potential, the Storm Prediction Center has issued a 'Marginal' thunderstorm risk for northern Utah on Wednesday, which means a few severe thunderstorms will be possible. With dry air near the surface, we will not likely see major precipitation, but storms could produce abundant lightning, small hail, and erratic wind. Once the trough exits the region, we will have a dry, southwest flow in place, allowing for hot temperatures and increased winds. The latter half of the work week could bring critical fire conditions to parts of central and southern Utah, with low relative humidity expected, heat and gusty winds in place. Stay tuned! We'll keep you posted on the latest updates in our 4Warn Weather forecast, both on-air and online, we are Good4Utah! Copyright 2025 Nexstar Media, Inc. All rights reserved.

It has never rained on June 11 in Phoenix. Could it happen this year? Here's what to know
Metro Phoenix's dry summer weather isn't surprising. However, residents may be shocked to know that there is one day it has never rained — June 11. Since the National Weather Service began keeping records nearly 130 years ago, Phoenix has only seen trace amounts of rain, meaning the moisture was so light that it was not measurable, according to meteorologist Mark O'Malley. That was in 1991. There are also two other dates — May 30 and June 16 — where just 0.01 inch of rain has fallen, O'Malley confirmed. Why is that? It's because June is the driest month in Phoenix. Here's why metro Phoenix sees such dry weather in June and what to expect this week. June is the driest month for metro Phoenix, O'Malley said. On average, only 0.02 inches of rain falls during the whole month. Most years, including 2023 and 2019, no rain falls during June. "Just to get rain on any single day is an uncommon occurrence," he said. This year, an early June storm system dumped more than an inch of rain around the northern reaches of metro Phoenix, hinting at more moisture ahead than the Valley has seen over recent summers. "The first part of monsoon is not as wet as later in the monsoon," O'Malley said. "You have to pull in a lot more moisture. For Phoenix specifically, we don't start to see thunderstorms due to monsoon until about the beginning of July." News alerts in your inbox: Don't miss the important news of the day.

"We're looking for seasonably warm conditions with high temperatures in metro Phoenix of 105 to 110 degrees and then getting hotter over the weekend," he said. Here is the weather forecast for Phoenix Sky Harbor International Airport, the official weather station, according to the weather service: June 10: Sunny during the day, with a high near 106. Light and variable wind becoming west 5 to 10 mph in the afternoon. Mostly clear at night, with a low around 81. West wind around 5 mph becoming calm after midnight. June 11: Sunny during the day, with a high near 107. Light southwest wind becoming west 5 to 10 mph in the afternoon. Clear at night, with a low around 81. West wind 5 to 10 mph becoming light west southwest after midnight. June 12: Sunny during the day, with a high near 108. Light and variable wind becoming west 5 to 10 mph in the afternoon. Mostly clear at night, with a low around 81. West southwest wind 5 to 10 mph becoming light and variable after midnight. June 13: Sunny during the day, with a high near 107. Calm wind becoming southwest around 5 mph in the afternoon. Mostly clear at night, with a low around 81. West wind around 5 mph becoming calm after midnight. June 14: Sunny during the day, with a high near 109. Calm wind becoming west around 5 mph in the afternoon. Mostly clear at night, with a low around 82. West wind around 5 mph becoming calm in the evening. June 15: Sunny and hot during the day, with a high near 111. Calm wind becoming west around 5 mph in the afternoon.
