Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 400 PM EDT Thu Apr 23 2020 Valid 00Z Fri Apr 24 2020 - 00Z Sun Apr 26 2020 ...Severe thunderstorm and flash flood threats will linger across the Southeast into early Friday morning... ...Severe thunderstorms and heavy rain possible from the Arklatex into the Mid-Mississippi River Valley on Friday... ...Record heat possible on Friday across southern Texas and the Southwest while conditions remain favorable for wildfires from western Texas into parts of New Mexico and Arizona. A storm system moving through the Tennessee Valley and Southeast will continue an ongoing threat for severe thunderstorms capable of producing tornadoes, large hail and severe straight-line winds mainly near and south of a warm front which extends through Georgia into the western Atlantic. Deep moisture from the Gulf of Mexico combined with favorable winds aloft will combine over the Southeast into Florida. Thunderstorms with this system will likely push offshore of the East Coast by early Friday morning but will linger across central to northern Florida into Friday afternoon. Up north, a cold rain can be expected for the northern Mid-Atlantic region into the Northeast before the cold front moves offshore for Friday night. Meanwhile, another storm system will be moving across the U.S., tracking from the Intermountain West into the Midwest early Friday morning into Saturday evening. While the deepest moisture will remain south of the front pushing offshore of the East Coast into Florida, sufficient dynamics aloft and a modest moisture return to the north will favor another round of potentially severe thunderstorms across the Arklatex on Friday/Friday night. This is where the Storm Prediction Center has a Slight Risk of severe thunderstorms. The greatest threat for heavy rain and flash flooding extend north of the severe thunderstorm risk with a Marginal Risk of flash flooding covering the Arklatex through the Mid-Mississippi River Valley for Friday into early Saturday. While cooler than average temperatures will persist for the Ohio Valley, Great Lakes and Northeast, record heat will be possible for southern California, southern Arizona and southern Texas. Forecast highs on Friday will be anywhere from the upper 80s to the low 100s. An Elevated to Critical threat is forecast by the Storm Prediction Center on Friday from southeastern Arizona into central and southern New Mexico as well as portions of western Texas given low relative humidities and gusty winds.
