Early Saturday Morning Edition

The storms approaching Shelby County last night really fizzled as the 10:00 hour came. Loss of daytime heating can do that. The official rainfall total from Memphis International was 0.17" of rain. Still the rain is a good thing. Even though we are well ahead for the year thanks to a wet March-May, it has been dry of late. Alright, where are we going from here? Let's dive in to the model runs:


This is the 6z GFS 500mb and vorticity map valid for 7:00 this evening. The heat is still on over the Southwest, as the ridge has built well into Canada at this time. The trough moving into British Columbia will help to flatten out the ridge into next week. The trough across the northeast appears to weakened somewhat. The northwest flow aloft continues. Coupled with a front sagging into the Southeast and humidity levels typical for summer, expect scattered showers and thunderstorms to be the weather story from Jackson (MS) to Birmingham to Atlanta.


And sure enough, there's the area of rain for today. Some good rain could fall over the Carolinas (a blessing at this point). Our temperatures will reach 84-86 today. It could be cooler depending on cloud cover, but mid 80s with a northerly breeze will make for a pleasant June day. Sunday will be more of the same, maybe a few degrees warmer, but nothing too oppressively hot.



Monday morning will feature more of the same for the Southeast. We might see a few showers in the morning, but other than that it looks dry to start the work week.

That's all for now. Updates later today, and more peeks into the GFS crystal ball, where snowstorms in the winter are the rule rather than the exception.
