Thursday Evening Map Discussion

Partly to mostly sunny skies dominate the weather across the Mid-South today with slightly warmer temperatures as the southerly flow returns to the area. As of 4 p.m. Memphis International Airport reported 86 degrees, which happens to be our high for the day, too. We'll be heading toward a low of 67 degrees tonight with partly cloudy skies. Now let's take a look at tomorrow...






Here is a look at the 18z NAM model run showing the weather for 1 p.m. Friday afternoon. You can clearly see the blob of precipitation across central Missouri. Also notice over northern Louisiana another batch of precipitation. Two systems will bring us chances for rain. A shortwave/piece of energy riding the NW flow aloft will move into the area enhancing lift and increasing rain chances. At the same time, a warm front will begin lifting north toward the Mid-South. The increase in moisture and approaching shortwave will kick off showers and thunderstorms. Fortunately, it appears the risk of severe weather will not be great. SPC only has us in the general thunderstorm area, but there will be some stronger storms possible.











Let's take a look at 1 p.m. Saturday courtesy the 18z GFS model run.





The majority of the rainfall should begin clearing out of West Tennessee and NE Arkansas as the cold front slides through the area. Northerly winds will keep the temperatures in the mid 80s for most locations. Much needed rainfall looks probable for the Carolinas, where the drought still continues. Iowa and the flooded Midwest continues to see dry weather, but with rivers still cresting, the catastrophic flooding continues.

I'll have an update Friday afternoon on the weekend and a look into future with the GFS crystal ball.
