Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 352 PM EDT Fri Apr 08 2022 Valid 00Z Sat Apr 09 2022 - 00Z Mon Apr 11 2022 ...Upper-level low to produce snow and rain showers over parts of the Great Lakes to Central Appalachians... ...There is a Critical Risk of fire weather over parts of the Plains and the Central Gulf Coast... ...Heavy snow for the Cascades... Deep upper-level low over the Upper Great Lakes to the Central Gulf Coast will aid in producing snow and rain showers over parts of the Great Lakes to Central Appalachians through Saturday. The snow and rain showers will slowly taper off from west to east overnight Saturday into Sunday. The heaviest snow amounts will be over the Central Appalachians and, to a lesser degree, downwind from the Great Lakes. Some of the rain showers will have embedded thunderstorms over the Ohio Valley into parts of the Northeast and Mid-Atlantic, with the greatest areal coverage on Friday and less on Saturday. Meanwhile, gusty winds, low humidity, and dry fuels have contributed to the SPC issuing a Critical Risk of fire weather over parts of the Plains and the Central Gulf Coast through Saturday morning. However, the fire weather threat will be over parts of the Southern High Plains and Southern Rockies on Saturday. In addition, upper-level ridging over portions of California and the Southwest will aid in producing tied or record high temperatures over the area through Friday evening. Furthermore, a front over Northern Plains to the Great Basin will move eastward to Upper Midwest to the Southern Plains by Sunday afternoon. As a result, light rain and snow will develop over parts of the Northern Intermountain Region early Friday evening. As the front passes, the snow levels will lower over the region as snow develops over the Northern Rockies by Saturday morning. The light snow continues over the Northern Rockies on Saturday. Overnight Saturday, the snow will begin to move into the Central Rockies. Nevertheless, light snow and rain showers will develop over parts of the Northern/Central High Plains on Sunday morning, expanding into the Upper Mississippi Valley by Sunday evening. Furthermore, light rain and thunderstorms will develop over parts of the Middle/Lower Mississippi Valley by Sunday evening. Moreover, a steady flow of moisture off the Pacific will produce heavy snow over the Northern Cascades on Friday evening into Saturday evening. The heavy snow will shift southward to the Southern Cascades from Saturday evening into Sunday evening. The moisture will also produce coastal rain over the Northwest through Sunday.
