A strong storm over the Central High Plains will move northeastward to the Middle Mississippi Valley by Friday. The system will produce snow over parts of the Northern/Central Rockies onto parts of the Northern Plains that will expand into parts of the Upper Mississippi Valley by Wednesday evening. The snow will expand into the Upper Great Lakes overnight Wednesday. In addition, a small area of showers and thunderstorms will develop over parts of the Central Plains on Wednesday with the showers and thunderstorms moving into parts of the Middle Mississippi Valley on Thursday. An Enhanced Risk of severe thunderstorms is in effect for the Central Plains in the Storm Prediction Center's outlook for Wednesday. As the storm moves out of the Plains, showers and thunderstorms will develop along and ahead of the associated front overnight Thursday into Friday over parts of the Ohio Valley into parts of the Tennessee/Lower Mississippi Valleys. Furthermore, a small area of rain/freezing rain and sleet will develop over parts of the Upper Great Lakes overnight Thursday into Friday. The storm will continue spread snow over parts of the Central/Northern Plains to the west and north of the surface low, and into the Upper Midwest on Wednesday. Blizzard conditions are expected as heavy and wet snow combines with strong wind. A swath of 1 to 2 feet of snow is forecast for the Central/Northern Plains and into Western Minnesota through Thursday evening, with locally higher amounts. Behind the storm and an associated dryline, conditions will be favorable for fire weather throughout the Southwest and Southern/Central Plains, as high sustained winds and even higher gusts combine with very dry humidities. An Extreme Risk of fire danger is in place in the Storm Prediction Center's Fire Weather Outlook for the Southern High Plains. Red Flag Warnings are widespread throughout these areas. More broadly, high winds are a threat from California through the Southwest, Intermountain West, Rockies and Plains for the next couple of days. Elsewhere, additional upper-level energy will move over the Pacific Northwest overnight Wednesday that will produce coastal rain and higher elevation snow over parts of the Northwest into the Northern Intermountain Region and parts of the Great Basin on Thursday into Friday.
