Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 309 AM EST Wed Jan 26 2022 Valid 12Z Wed Jan 26 2022 - 12Z Fri Jan 28 2022 ...Snow over the southern Rockies/High Plains will spread toward Oklahoma tonight... ...Large temperature swings across the northern U.S. as arctic air moderate slowly over the eastern and southern U.S.... ...A low pressure wave will bring some showers and possibly thunderstorms across southern Florida today and into Thursday... An upper level trough digging southward into the southern Rockies will continue to bring a good chance of snow across the northern half of New Mexico this morning before swinging eastward across the Texas Panhandle and into Oklahoma later today into tonight. Much of these areas should receive 1 to 3 inches of snow, although snow bands may lead to localized higher amounts. This area of snow should gradually taper off as the upper level trough weakens and tracks east toward the mid-Mississippi Valley Wednesday night. Caught in between mild air that builds up over the High Plains and a pair of arctic cold fronts forecast to plunge from Canada, the northern tier states will experience large temperature swings through the next couple of days. Frigid conditions across the upper Midwest this morning will be quickly followed by milder than normal conditions by Thursday before another arctic surge reaches the area Thursday night. Mainly light snow is expected to accompany the arctic front as it sweeps through the Great Lakes on Thursday. Meanwhile, arctic air that has settled across the eastern and southern U.S. will moderate slowly during the next couple of days. Elsewhere, a low pressure wave will bring some showers and possibly thunderstorms across southern Florida today and into Thursday. This wave is forecast to become nearly stationary just east of Florida through Friday morning, with rain chances gradually decreasing over Florida. For the West, dry and mostly quiet weather is anticipated. In contrast, rain chances are forecast to increase across southern Texas Thursday night as another upper level impulse dipping through the Rockies interacts with a developing frontal boundary.
