Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 353 PM EDT Sun Apr 04 2021 Valid 00Z Mon Apr 05 2021 - 00Z Wed Apr 07 2021 ...Much warmer than average temperatures in the western and central U.S. will support Elevated Risks of fire weather... ...Moisture from the Gulf of Mexico will produce showers and thunderstorms over parts of the Upper Midwest, the Plains, and Ohio Valley overnight Monday into Tuesday... The Southwestern to Upper Midwest will experience temperatures 15 to 25 degrees above average as a broad upperâ€level ridge takes shape through Tuesday evening. The Desert Southwest should see temperatures in the upper 90s and nearing 100 degrees, while 80s are forecast for Northern Plains and the Central/Southern High Plains. Additionally, several daily high-temperature records could be set. These warm temperatures combined with dry soils, low relative humidity, and gusty winds will lead to the potential for fire weather. Per the SPC, Fire Weather Outlook indicates an Elevated Risk across parts of Montana and Central High Plains. On Monday, the risk will be Critical over portions of Nevada into the Four Corners region. Meanwhile, parts of Southern New England and northern Mid-Atlantic will have an Elevated Risk. In the meantime, a front extending from the Northern High Plains southwestward to the northern California coast will slowly move eastward to the Northern/Central Plains roughly southwestward to the Southwest U. S. by Tuesday evening. The associated upper-level trough will help produce higher elevation snow and rain over parts of the Northwest into the Northern Intermountain Region. Overnight Sunday, snow will develop over parts of the Northern Rockies that will slowly move southeastward into parts of the Central Rockies later Tuesday morning. The snow will continue over the Central Rockies and trickle into parts of the Central High Plains Tuesday afternoon. Furthermore, moisture pooling over the Plains will help produce showers and thunderstorms over parts of the Central Plains into parts of the Middle Mississippi Valley overnight Sunday. Rain and showers/thunderstorms will move into parts of the Upper Great Lakes by Monday morning and into parts of the Ohio Valley by Monday evening. Overnight Monday, as the associated front moves southward, showers and thunderstorms will develop over parts of the Upper/Middle Mississippi Valley and expand into parts of the Central/Southern Plains on Tuesday into Tuesday evening. The SPC has issued a Slight Risk of severe thunderstorms over this area on Tuesday. Furthermore, Rain will move into parts of the Ohio/Tennessee Valleys and into parts of the Mid-Atlantic by Tuesday evening. Elsewhere, rain and snow will develop from wrap-around moisture from a slow-moving surface low in the Atlantic off Maine's coast.
