Flash Flood Watch From I-20 South

An all new edition of the ABC 33/40 Weather Xtreme video is available in the player on the right sidebar of the blog. You can subscribe to the Weather Xtreme video on iTunes by clicking here.

TOO MUCH RAIN: The NWS in Birmingham is continuing a flash flood watch for Tuscaloosa, Birmingham, Anniston (the I-20 corridor) and points south through tomorrow night as periods of rain will continue thanks to a stalled front nearby. We don’t expect any severe weather over the northern two-thirds of the state, just rain at times with a little thunder in the mix. Even down in far South Alabama the severe weather risk is somewhat marginal tomorrow and tomorrow night.

Additional rain amounts of one to two inches are likely for our part of the state (I-20 corridor), with heavier amounts, possibly to three inches, down south over the southern counties of Alabama. The heaviest rain, most likely, comes tomorrow into tomorrow night as a surface wave of low pressure moves along the stalled front.

The rain will finally end Wednesday morning as the wave moves northeast of the state, but clouds should linger all day Wednesday.

BRIGHTER DAYS: Thursday and Friday will feature a good supply of sunshine, with temperatures where they should be in mid-February. Highs in the 50s, lows in the 30s.

ARCTIC BLAST SATURDAY: A strong northern stream disturbance will bring a shot of very cold, Arctic air into Saturday to kick off the weekend. I figure we won’t get out of the 30s with a very chilly north wind. And, yes, strong upward motion from the upper trough will bring the risk of a few show flurries or showers to the state, but moisture is very limited and really significant accumulation doesn’t look likely for now. The one thing to watch for is the potential for convective snow showers across the northern third of the state due to very cold air aloft; those can make the ground white pretty quickly, but they should be scattered and move along quickly.

Sunday morning will be very cold. As the sky clears and the wind dies down, we project lows in the 18-23 degree range. Then, during the day Sunday we expect a good supply of sunshine, and a warming trend begins with a high around 50 degrees. Dry weather should linger into Monday.

THE LAND OF VOODOO: The GFS hints at another cold shot with some potential for a little snow Feb 19-20… see the Weather Xtreme video for the maps, graphics, and details.
