A variety of winter advisories, watches and warnings in affect across the U.S. this evening. Freeze warnings stretch from the panhandle of TX to southern MI in the wake of a cold front that passed through the area on Friday. This will essentially end the growing season for much of the Plains and Midwestern states as temperatures drop below freezing tonight and stay there for several hours. Frost advisories are in effect in the Northeast, central IL and IN, and southwestern OR.
Winter weather advisories are in effect for central WY and northeast NE where it is currently (10:30 MDT) snowing. Total accumulations are expected to reach 3-6 inches in the area with 4-8 inches likely at higher elevations. This system will move out into the central Plains tonight and through tomorrow. As a result, a winter storm watch is in effect for northern NE, southern and east central SD, as well as west central MN. The storm is forecast to produce 4-6 inches of snow in the watch area.
The winter weather advisory in northwestern KS is for freezing drizzle and fog, mixed with snow, to develop tonight and potentially affect the area tomorrow. Temperatures are not expected to climb much, if at all, above freezing during the day on Sunday. Another advisory is in place in the upper peninsula of MI where lake effect snow showers, wind, and blowing snow are combining to make driving quite hazardous.
