Extreme weather…Radar estimates 6-8 in. of rain in southwest Mississippi into Louisiana stretching northeast to east-central Mississippi caused by a slow-moving severe weather and heavy rain event which developed yesterday. Flash flood warnings are in effect from Hattiesburg to Demopolis, MS. The excessive rainfall weakens shifting southeast across the far western Florida Panhandle today. The west/north Great Plains blizzard is winding down although high wind causing blowing and drifting snow continues in South Dakota. The snowstorm (featuring blizzard conditions) continues in New Mexico. Finally, sneaky high wind (45-55 mph gusts) were observed across the Ohio Valley yesterday and these wind speeds shift to the Mid-Atlantic/Northeast U.S. today likely in the 35-50 mph range. More rain…Another heavy rain event early next week Texas/Mid-South to Mid-Atlantic States. More heavy rain across the Southeast U.S. late next week. A snowy New Year’s Day in Chicago! Warm New Year’s Day in the East but by late next week extreme arctic cold gathers in Eastern Canada and may touch NY/New England. Medium-range…The day 6-10 trend is warmer North and East U.S. while Texas/New Mexico is rain-cooled. An east-shifting MJO episode across the tropical Pacific supports this forecast. In the 11-15 day period much of the nation is warm with marginal cold risk in the Northeast.
