Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 317 AM EST Sun Mar 06 2022 Valid 12Z Sun Mar 06 2022 - 12Z Tue Mar 08 2022 ...New system to produce severe weather and flash flooding from the ArkLaTex to the Ohio Valley... ...Moderate to heavy snow forecast across the Rockies... ...Record-breaking warmth expected throughout parts of the East; Critical Fire Weather risk remains over the Southern/Central Plains today... A series of shortwaves rotating around an upper-level trough will promote an active weather pattern throughout much of the central and eastern CONUS over the next couple of days. A deep and dynamic low pressure system responsible for freezing rain over the Upper Midwest yesterday will generate gusty winds across the Midwest today as it departs into southeastern Canada. High wind warnings and advisories are in effect for much of the Midwest and Great Lakes as a result. Meanwhile, another shortwave trough will emerge over the Great Plains today, spawning an area of surface low pressure over the Lower/Middle Mississippi Valley. This surface low will develop along a trailing cold front from the departing Midwest system. This boundary will become the focus for severe weather across portions of the Southern Plains, Lower/Middle Mississippi Valley, and Tennessee/Ohio Valley today, where the Storm Prediction Center issued a Slight Risk of Severe Thunderstorms. An Enhanced Risk of Severe Thunderstorms is in effect for the Missouri/Arkansas border today. The main risks associated with today's severe weather will be a few tornadoes and damaging wind gusts. Heavy rainfall leading to potential flash flooding will occur along the surface front over the Lower/Middle Mississippi Valley and Ohio/Tennessee Valley today due to the continued fetch of moisture pumping into the region from the Gulf of Mexico. A Slight Risk of Excessive Rainfall is in effect as a result. Light snow will spread from the Central Plains to the Upper Great Lakes today within the cold sector of the developing system. The focus for flash flooding and severe thunderstorms shifts eastward into the Ohio/Tennessee Valleys and Southeast on Monday, where heavy rain and damaging wind gusts will cause problems. Elsewhere, a strong warm front associated with the departing low pressure system will gradually lift through the Northeast today allowing for very mild air to settle over the eastern U.S. through Monday. Temperatures are likely to be between 20-30 degrees above average in many places. This will lead to the likelihood of widespread high/low temperature records being tied or broken today and Monday. Warm temperatures paired with dry conditions and gusty winds will continue to promote the chance for fire weather over parts of the Central/Southern Plains today. A Critical Fire Weather Risk is in effect for parts of the Texas/Oklahoma Panhandle and central Oklahoma/Kansas. A cold front should sweep across the South and East Monday evening, moderating temperatures in its wake. High pressure will continue pushing through much of the western half of the country today. High temperatures over the Front Range are likely to be 20-30 degrees below average today and tomorrow. The shortwave responsible for generating today and tomorrow's hazardous weather over the central U.S. will also produce heavy snowfall over parts of the Central/Southern Rockies. A weaker piece of shortwave energy will generate lighter snow over the same area tonight before things quiet down. Additional troughing from western Canada will drop down into the Pacific Northwest by Tuesday morning. This trough will pull Pacific moisture into the region, which will produce low elevation rain and mountain snow over the Cascades and Northern Rockies.
