305 FXUS01 KWBC 060602 PMDSPD Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 202 AM EDT Mon Apr 06 2026 Valid 12Z Mon Apr 06 2026 - 12Z Wed Apr 08 2026 ...Chances for heavy rain and thunderstorms over parts of the Florida Peninsula over the next couple of days... ...Chances for wintry mix over the Northern Plains into the Great Lakes and Northeast... ...Critical fire weather concerns for central/southern High Plains... Much of the cold front that has been bringing some active weather across the East Coast will push offshore with the exception of the lingering slow moving/stationary front that sits across the Gulf into Florida. This will bring chances for heavy rain and thunderstorms over the next few days, especially with the combination of moist tropical airmass and instability over the Florida Peninsula. This will pose a marginal risk for excessive rainfall and flash flooding over parts of Florida. Over northern U.S., a cold frontal system will drop southeast on Monday, bringing chances for precipitation and gusty winds over the Great Lakes into the Northeast. As the cold air mass combines with the moisture and lake snow effect takes place, chances for light to moderate snow increases over the Great Lakes. The front advances eastward bringing chances for snow showers over New England before it exits the region by Wednesday and is replaced with drier conditions from the high pressure system. Over to the west, several shortwave troughs will develop over the Southwest and Pacific Northwest, bringing chances for showers and thunderstorms over much of Oregon and over New Mexico, Arizona, and Utah on Monday and will move eastward over into the southern Rockies on Tuesday. In addition, a frontal system will drop into the Pacific Northwest/Northern Rockies on Monday and will stretch across much of central U.S. into the Mid-Atlantic. This front will bring chances for a changeover from rain to snow/wintry mix late Monday into Tuesday over the Missouri Valley/Corn Belt. As the closed low moves into the Northern Plains on Tuesday, the associated front will bring mixed precipiation over much of the Northern Plains, Upper Midwest, and Great Lakes Tuesday evening into Wednesday. The moisture will also stretch downward into the Southern Rockies/Plains, reinforcing showers and thunderstorms on Tuesday into Wednesday. A strong high pressure system will drop southward from Canada bringing drier conditions and gusty southerly winds across portions of Oklahoma, Texas, New Mexico, Colorado, and Kansas on Monday. With the additional of low relative humidity values, fire weather concerns have upgraded from Elevated (level 1/3) to Critical (level 2/3). Below normal temperatures will continue across Northern Plains into New England with highs reaching below freezing over the Northern Plain on Monday and New England on Tuesday. Above normal temperatures will continue for much of Western U.S. through Tuesday. Across much of CONUS will gradually return closer to normal by Wednesday.
