Decatur, Alabama
Off to the Deep South, where it NEVER thunderstorms this time of year...
At 1:53pm CDT, the temperature at Decatur, AL was 80 degrees under fair skies. A few thunderstorms are found just off towards the east near Huntsville, but otherwise right now seeing a little break in the action. The overall regime for the next couple of days doesn't look to be changing much as the main jet stream stays fairly zonal over the northern tier of the US. A Bermuda High looks to stay rather persistent over... well... Bermuda, which keeps a general southerly flow going over the Southeastern US, keeping the flow of moisture from the Gulf open. Add in the normal afternoon instability that always results when temperatures push into the 80s and 90s over the region, and you get scattered thunderstorms over pretty much the entire area every afternoon. Just be sure to keep an eye on the radar as these types of thunderstorms seem to pop up quickly and die out just as fast. Happy Memorial Day readers!
