Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 400 PM EDT Fri May 31 2024 Valid 00Z Sat Jun 01 2024 - 00Z Mon Jun 03 2024 ...There is a Slight Risk of severe thunderstorms over parts of the Central/Southern High Plains and Lower Mississippi Valley on Friday, over parts of the Central/Southern High Plains on Saturday, and Northern/Central Plains/Upper Mississippi Valley on Sunday... ...There is a Slight Risk of excessive rainfall over parts of the Southern Plains and Middle/Lower Mississippi Valley on Friday, Tennessee Valley/Central Gulf Coast/Southeast on Saturday, and Upper/Middle Mississippi Valley and Northern/Central Plains on Sunday... ...There are Heat Advisories over southern Texas... Moisture streaming northward over the Plains and a dryline over western Texas will aid in creating showers and severe thunderstorms over parts of the Central/Southern High Plains. Therefore, the SPC has issued a Slight Risk (level 2/5) of severe thunderstorms over the Central/Southern High Plains through Saturday morning. The hazards associated with these thunderstorms are frequent lightning, severe thunderstorm wind gusts, hail, and a minimal threat of tornadoes. A second area of showers and severe thunderstorms will develop over the Southern Plains. Therefore, the SPC has issued a Slight Risk (level 2/5) of severe thunderstorms over parts of the Southern Plains through Saturday morning. The hazards associated with these thunderstorms are frequent lightning, severe thunderstorm wind gusts, hail, and a minimal threat of tornadoes. A third area of showers and severe thunderstorms will also develop over parts of the Lower Mississippi Valley. Therefore, the SPC has issued a Slight Risk (level 2/5) of severe thunderstorms over parts of the Lower Mississippi Valley through Saturday morning. The hazards associated with these thunderstorms are frequent lightning, severe thunderstorm wind gusts, hail, and a minimal threat of tornadoes. In addition, the showers and thunderstorms will create heavy rain over parts of the Southern Plains and Middle/Lower Mississippi Valley. Therefore, the WPC has issued a Slight Risk (level 2/4) of excessive rainfall over parts of the Southern Plains and Middle/Lower Mississippi Valley through Saturday morning. The associated heavy rain will create mainly localized areas of flash flooding, with urban areas, roads, small streams, and low-lying areas the most vulnerable. On Saturday, the same set-up over the Southern Plains, moisture streaming northward over the Plains, and a dryline over western Texas will create showers and severe thunderstorms over the region. Therefore, the SPC has issued a Slight Risk (level 2/5) of severe thunderstorms over the Central/Southern High Plains from Saturday through Sunday morning. The hazards associated with these thunderstorms are frequent lightning, severe thunderstorm wind gusts, hail, and a minimal threat of tornadoes. Moreover, showers and thunderstorms will develop over parts of the Tennessee Valley/Central Gulf Coast/Southeast, creating heavy rain. Therefore, the WPC has issued a Slight Risk (level 2/4) of excessive rainfall over parts of the Tennessee Valley/Central Gulf Coast/Southeast from Saturday through Sunday morning. The associated heavy rain will create mainly localized areas of flash flooding, with urban areas, roads, small streams, and low-lying areas the most vulnerable. On Sunday, a weak front over the Northern Intermountain Region on Saturday afternoon will advance eastward to the Northern Plains and Upper Mississippi Valley, producing showers and severe thunderstorms over parts of the region. Therefore, the SPC has issued a Slight Risk (level 2/5) of severe thunderstorms over the Northern/Central Plains/Upper Mississippi Valley on Sunday. The hazards associated with these thunderstorms are frequent lightning, severe thunderstorm wind gusts, hail, and a few tornadoes. Furthermore, showers and thunderstorms will cause heavy rain over the Upper/Middle Mississippi Valley and Northern/Central Plains. Therefore, the WPC has issued a Slight Risk (level 2/4) of excessive rainfall over parts of the Upper/Middle Mississippi Valley and Northern/Central Plains on Sunday morning. The associated heavy rain will create mainly localized areas of flash flooding, with urban areas, roads, small streams, and low-lying areas the most vulnerable. Meanwhile, onshore flow and a steady stream of upper-level energy over the Pacific Northwest will trigger rain over parts of the Pacific Northwest from early Saturday into Sunday. Furthermore, a developing upper-level ridging over southern Texas will aid in spawning Heat Advisories over southern Texas.
