Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 242 AM EST Sat Mar 08 2025 Valid 12Z Sat Mar 08 2025 - 12Z Mon Mar 10 2025 ...Heavy Snow spreads from Southern Rockies this morning into Southern High Plains this afternoon... ...Cold front ushers in cooler air across Southern states while northern tier warms up... ...Critical Fire Weather for parts of west/south-central Texas today... A split flow pattern featuring an amplified southern stream trough will support unsettled weather from New Mexico to Florida this weekend. Ongoing snow showers over the Sangre De Cristo Mountains and foothills of the Southern Rockies this morning are likely to spread into the Texas/Oklahoma Panhandles this afternoon. Generally, 3-6 inches of additional snow is probable when it's all said and done. Winter Storm Warnings and Winter Weather Advisories remain in effect through this morning. Meanwhile, scattered rain showers and thunderstorms are expected across much of Oklahoma. The associated low pressure system will weaken while it moves across the Gulf Coast this weekend; generating scattered rain showers and thunderstorms along its path. Excessive Rainfall and Severe Thunderstorm Risks remain Marginal at this time, due in part to the progressive nature of the system. Cooler temperatures are expected on the backside of the cold front. Highs in the 30s and 40s over parts of eastern New Mexico and the Texas/Oklahoma Panhandles will be 15-30 degrees below average today, while parts of the Northeast experience highs that are between 10-20 degrees below average. Very dry (10-20% RH) and gusty winds (up to 35 mph) behind the attendant cold front will support a Critical Risk of Fires across portions of the Texas Trans-Pecos and Middle Rio Grande Valley today. Red Flag Warnings are in effect until 8pm CST this evening. Elsewhere, ridging in the West with embedded shortwave energy moving through southern Canada will support southerly flow with an increasingly warmer airmass throughout the region this weekend. Highs in the 50s and 60s across the Northern Plains and Upper Midwest will be 15-30 degrees above average for this time of year, with peak anomalies occurring on Sunday and Monday. Persistent troughing in the East Pacific will continue to produce moist onshore flow and heavy mountain snow over the Olympics and Cascades this weekend. A series of shortwave energy cycling through the Northeast will produce some light snow showers over the Adirondacks and Green/White Mountains this weekend. Very light snow will also persist downwind of the Great Lakes with little to no impacts likely from that. Kebede Graphics available at https://www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
