Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 359 PM EDT Sun Apr 08 2018 Valid 00Z Mon Apr 09 2018 - 00Z Wed Apr 11 2018 ...Snow spreads from the Northern Plains and Mississippi Valley to portions of the Ohio Valley Sunday night and Central Appalachians Monday morning... ...Elevated to critical fire weather is forecast for New Mexico and West Texas... ...Cold temperatures continue in the East while warm temperatures return to the West... An upper-level disturbance will move from the Northern Plains through the Upper Midwest Sunday night and into the Ohio Valley on Monday. This combined with cold temperatures up to 25 degrees below average will lead to snow in these areas. Through Sunday evening and night, a few additional inches of snow are possible through the Northern Plains and parts of the Upper Midwest, where Winter Weather Advisories and a few Winter Storm Warnings are in effect. Light snow will spread into the Ohio Valley and into the Central Appalachians by Monday morning, where up to 2 inches of snow is forecast. Additionally, a stationary front located just east of the Rockies will lead to continued snow in the Rockies too through Monday morning. Higher peaks could see 4 to 6 additional inches of snow. Dry and windy conditions will continue into Sunday evening in New Mexico and West Texas, so conditions are favorable for fires there. Critical fire weather conditions are forecast by the Storm Prediction Center, and widespread Red Flag Warnings are in effect Sunday. There is an elevated risk of fire weather again during the day on Monday. A frontal system will linger through the beginning of the week across the Gulf of Mexico and Florida, helping cause scattered showers and thunderstorms along the Gulf Coast and in the Carolinas. Rain and storms will become more widespread across Florida by late Monday as a surface low moves across the state. The Northwest will once again see precipitation by Tuesday as another low approaches. This will mainly be light rain except in the highest elevations. Temperature-wise, chilly weather will continue east of the Rockies through the beginning of the workweek. As mentioned, temperatures up to 25 degrees below average are forecast in some areas, including the Northern Plains and into the Central Appalachians. Temperatures will moderate somewhat on Tuesday but still be below average. The exception is the Florida peninsula, which will remain in the 80s for high temperatures, even warmer than average. On the other side of the U.S. along the West Coast, temperatures will be above normal as well--up to 20 degrees above in some areas. Some record high minimum temperatures are expected Tuesday morning. Tate Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
