Over the next couple of days, a cold front will push slowly southward through Texas and farther east, will linger near the Central Gulf Coast over the Lower Mississippi Valley and Southeast. Along this front and with moist air in place, scattered showers and thunderstorms are likely. Generally, 1 to 2 inches of rain is expected across parts of the Lower Mississippi Valley and Southeast through Friday morning. Marginal Risks of flash flooding and severe weather (per the Storm Prediction Center) are in place for these areas. Cold temperatures and an upper-level disturbance will lead to accumulating snow across the Central Plains on Wednesday night into Thursday. Winter Weather Advisories are in effect there, as 2-6 inches of snow is forecast. Light snow is possible for the Middle Mississippi Valley as well. Temperatures will be much below average for most of the Plains on Wednesday and Thursday, by 15 to 25 degrees in the Northern Plains on Wednesday and in the Central Plains on Thursday. Lake effect snow is forecast for the Upper Great Lakes over the next couple of days, with lake effect rain and snow showers possible in the Lower Great Lakes. As a low pressure system develops, snow chances in the Great Lakes region will increase by Friday morning. In the West, snow is expected across the Northern Rockies on Wednesday as a stationary front lingers there, and Winter Weather Advisories are in effect. The rest of the West will remain dry--too dry in northern California. Fire weather danger will ramp up there over the next couple days as winds increase and relative humidities are forecast to be only 5-20%, even at nighttime. Critical Fire Weather is outlooked from the Storm Prediction Center, and Red Flag Warnings are in effect. Tate Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
