The Monday morning web video update is on the server:
http://beta.abc3340.com/weather/video.hrb
SPC has placed parts of Ark-La-Miss region under a moderate risk of severe storms today, including places like Jackson, Vicksburg, Monroe, and Eldorado. A slight risk surrounds the moderate risk, as far east as I-65.
Here is the deal...
A strong, negative tilt upper trough over the plains states will generate thunderstorms during the day today well to the west, and over that moderate risk there could be a few significant tornadoes as all of the parameters will fall into place. By tonight, storms should evolve into a long squall line as the main threat shifts to damaging straight line winds. The storms should be near the Alabama/Mississippi border sometime between midnight and 3:00 a.m.
The storms will sweep through Alabama from about 2:00 a.m. until 11:00 a.m., but the instability, helicity, and wind fields are all rather marginal. The greatest chance of damaging winds will come over the western third of the state, with the threat diminishing over the eastern counties with a drier and more stable airmass in place.
Rain totals of one-half to one inch seem likely, not enough to trigger any flash flooding.
We will continue to mention the chance of isolated showers or storms on Wednesday and Thursday as the upper low passes to the north of us, but widespread rain isn't likely.
The weekend ahead looks dry and pleasant. Two nice weekends in a row... not bad!
THE LONG RANGE: Sure looks like the ole Bermuda ridge will show up over the latter half of the month, which could serve to keep the big storm systems west and north of Alabama. This could lead to a generally drier and warmer pattern for us...
Headed out to Inglenook Elementary today in Birmingham for a meteorology program... be back in the office later today for the afternoon update.
