Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 404 PM EDT Sat Jun 01 2024 Valid 00Z Sun Jun 02 2024 - 00Z Tue Jun 04 2024 ...There is an Enhanced Risk of severe thunderstorms over parts of the Central/Southern High Plains on Saturday and over parts of the Central High Plains on Sunday... ...There is a Moderate Risk of excessive rainfall over parts of the Central Gulf Coast on Saturday... ...There is a Slight Risk of excessive rainfall over parts of the Pacific Northwest, Northern Intermountain Region, Upper/Middle Mississippi Valley, and Northern/Central Plains on Sunday and the Northern Intermountain Region on Monday... ...There are Heat Advisories over western 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, through Sunday morning, the SPC has issued an Enhanced Risk (level 3/5) of severe thunderstorms over the Central/Southern High Plains. The hazards associated with these thunderstorms are frequent lightning, severe thunderstorm wind gusts, hail, and a few tornadoes. In addition, there is a threat of severe thunderstorm wind gust, of 65 knots or greater and hail, two inches or greater over parts of the Central/Southern High Plains. Moreover, there is a second area of hail, two inches or greater, over parts of western Texas and southeastern New Mexico. Further, upper-level energy will aid in producing showers and severe thunderstorms over parts of the Western Gulf Coast. Therefore, the SPC has issued a Slight Risk (level 2/5) of severe thunderstorms over the Western Gulf Coast through Sunday morning. The hazards associated with these thunderstorms are frequent lightning, severe thunderstorm wind gusts, hail, and a few tornadoes. Moreover, showers and thunderstorms will develop over parts of the Central Gulf Coast, creating heavy rain. Therefore, the WPC has issued a Slight Risk (level 2/4) of excessive rainfall over parts of the Central Gulf Coast 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. Additionally, showers and thunderstorms will develop over parts of the Central/Southern High Plains, creating heavy rain. Therefore, the WPC has issued a Slight Risk (level 2/4) of excessive rainfall over parts of the Central/Southern High Plains 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 cold front extending from the Northern Plains to the Great Basin will move eastward to the Upper/Middle Mississippi Valley by Monday, producing showers and severe thunderstorms over parts of the Central High Plains. Therefore, the SPC has issued an Enhanced Risk (level 3/5) of severe thunderstorms over the Central High Plains from Sunday through Monday morning. The hazards associated with these thunderstorms are frequent lightning, severe thunderstorm wind gusts, hail, and a few tornadoes. In addition, there is a threat of severe thunderstorm wind gust, of 65 knots or greater. Moreover, a second area of severe thunderstorms will also occur over the Southern High Plains on Sunday. Therefore, the SPC has issued a Slight Risk (level 2/5) of severe thunderstorms over the Southern High Plains from Sunday through Monday morning. 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 from Sunday through Monday 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 Monday, the threat of severe thunderstorms and excessive rainfall will decrease slightly over the Middle/Mississippi Valley and Central/Southern Plains. Therefore, there will be a Moderate Risk of severe thunderstorms and excessive rainfall over the area. Meanwhile, onshore flow and a steady stream of upper-level energy over the Pacific Northwest will trigger rain and snow melt over parts of the Pacific Northwest into the Northern Intermountain Region from early Saturday into Monday. On Sunday the rainfall will increase, therefore, the WPC has issued a Slight Risk (level 2/4) of excessive rainfall over parts of the Pacific Northwest from Sunday through Monday 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. Additionally, the heavy rain and snow melt will develop over parts of the Northern Intermountain Region. Therefore, the WPC has issued a Slight Risk (level 2/4) of excessive rainfall over parts of the Northern Intermountain Region from Sunday through Monday 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. Moreover, on Monday, the rain and snow melt will produce heavy rain over parts of the Northern Intermountain Region. Therefore, the WPC has issued a Slight Risk (level 2/4) of excessive rainfall over parts of the Northern Intermountain Region on Monday. 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. Furthermore, a developing upper-level ridging over southern Texas will aid in spawning Heat Advisories over Western Texas.
