FXUS01 KWBC 091953 PMDSPD Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 352 PM EDT Thu Apr 09 2026 Valid 00Z Fri Apr 10 2026 - 00Z Sun Apr 12 2026 ...Scattered severe thunderstorms and heavy rain across the Central Plains and Mid-Mississippi Valley Friday into Saturday... ...Active weather pattern intensifies across the Western U.S. with heavy mountain snow and valley rain... ...Widespread above-average temperatures continue for the Central and Eastern U.S. while the West Coast cools... A persistent frontal boundary stretching from the central Great Basin through the Ohio Valley will remain the primary focus for unsettled weather. Scattered showers and thunderstorms are expected to persist tonight along this boundary from the Missouri Valley into the Great Lakes, with a few stronger storms capable of producing large hail and heavy rain across southeast Nebraska and southern Iowa. As warm, moist air from the Gulf surges northward to interact with this front, widespread showers and thunderstorms are expected to develop. The Storm Prediction Center has highlighted a risk for severe thunderstorms across portions of the Central and Southern Plains for Friday afternoon and evening, specifically for eastern New Mexico into the Texas and Oklahoma Panhandles, where large hail and damaging winds are the primary threats. By Friday night and Saturday, the focus for heavy rainfall shifts towards the Mid-Mississippi Valley and Southern Plains, where localized flooding is possible due to high moisture levels. In the West, a mature low pressure system off the Pacific coast will move inland Friday and Saturday. This system will bring a significant pattern change characterized by widespread rain, isolated thunderstorms, and heavy mountain snow. Significant snowfall accumulations are expected for the Sierra Nevada at higher elevations. Widespread rain and cooling temperatures will spread across California and the Great Basin, eventually reaching the Northern Rockies by Saturday. Temperature trends will remain highly variable across the country. Much of the Central and Eastern U.S. will experience a significant warming trend, with temperatures averaging 10 to 20 degrees above seasonal norms. Unseasonable warmth will become more common across the Plains and the Southeast, with some record-breaking highs possible by Saturday. Conversely, the West Coast and Northern Plains will remain cooler; the West will see temperatures drop below normal as the Pacific storm moves through, while parts of the Northeast and Great Lakes recover from a recent cool spell to near-normal seasonable values. High fire danger persists in the Southeast and Mid-Atlantic due to dry conditions and low humidity. Eovino Graphics available at https://www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php $$
