Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 303 AM EDT Sun Jun 8 2025 Valid 12Z Sun Jun 8 2025 - 12Z Tue Jun 10 2025 ...Active severe weather setup from the southern Plains to the Southeast this weekend and into Monday... ...Heavy showers & thunderstorms to pose both a flash flooding and severe weather threat in parts of the Midwest and Mid-Atlantic... ...Stifling heat dome to build in throughout much of the West and the western Gulf Coast; hottest temperatures compared to normal centered over the Northwest... The main thing making weather headlines over the next couple of days will be the potential severe weather outbreak across portions of Oklahoma and northern Texas on Sunday. The Storm Prediction Center has a Moderate Risk of severe thunderstorms from the Texas Panhandle to just north of the greater Dallas/Fort Worth metroplex. There will likely be scattered to numerous supercells that evolve into multiple mesoscale convective systems (MCS), with damaging winds and large hail the primary threats, and some tornadoes are also a possibility. An approaching cold front from the north will intercept a highly unstable environment east of the dry line, and fuel the development of intense convection going into the afternoon and evening hours. In addition to the severe weather threat, periods of heavy rainfall may lead to some instances of flash flooding across this same general area through early Monday morning, with some areas potentially getting 2 to 4 inches of rain. Another area of stormy weather is expected to be across coastal portions of the Southeast U.S. into the Mid-Atlantic on Sunday as a wave of low pressure and an upper level disturbance moves overhead, where a Slight Risk of both severe weather and excessive rainfall is valid, with the heaviest rain mainly confined to Virginia and eastern West Virginia. More heavy showers and thunderstorms are likely for the beginning of the work week across much of the Southeast U.S. as a frontal boundary stalls across the region. Farther north across Pennsylvania into Upstate New York, a line of thunderstorms with heavy rainfall is likely to develop ahead of a cold front on Monday. Elsewhere across the Continental U.S., widespread anomalous heat will continue to affect interior portions of the Pacific Northwest through Monday with heat advisories in effect from northern California to eastern Washington and northern Idaho, and daily record highs are likely for some areas. It will also continue to be uncomfortably hot and humid from Texas and extending east across the Gulf Coast, with high dewpoints and temperatures in the upper 80s to middle 90s making it feel over 100 degrees at times during the afternoon hours. Air quality alerts are in effect across portions of the Northeast and also the Upper Midwest as wildfire smoke from distant Canadian wildfires continues to infiltrate those areas. There is also an elevated wildfire risk across eastern portions of Montana on Sunday. Hamrick Graphics available at https://www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
