WATERLOGGED: A strong short wave moving through Texas will enhance rain across Alabama later today and tonight. While the rain is fairly light and spotty early this morning, the rain will be more widespread and heavier from about 12:00 noon until midnight tonight. Additional rain amounts of one to two inches are likely, and the NWS in Birmingham continues a flash flood watch for areas along and south of I-20 through tonight.

FOR THE YEAR: For those asking… Birmingham’s rain total for the year is now 10.37″, and the surplus for the year is 3.80″.

Some light rain could linger into tomorrow morning, and the sky will stay cloudy through the day, but we have great hope of brighter weather as the sun returns in full force on Thursday. We project a high in the upper 50s Thursday afternoon.

QUICK HITTING COLD SHOT: Two fronts will pass through Alabama; the first one will move through North Alabama in Friday fashion Friday afternoon. For the I-20 corridor, we expect a high around 60 degrees Friday with a decent amount of sun, but our friends in the Tennessee Valley will have a high closer to 50 as colder air blows into the state.

SNOW FLAKES SATURDAY? The second front, an Arctic front, will usher in very cold air Saturday. I doubt if we get out of the 30s; the ECMWF hints some of our friends near the Tennessee border won’t get above freezing. Factor in a north wind of 8-16 mph and it will feel even colder.

Models have been waffling on the amount of moisture available Saturday as a very deep, cold upper trough passes overhead. The 00Z runs of the GFS and ECMWF have trended drier, and we won’t change our ongoing forecast. We have mentioned just the chance of a few light snow flurries or snow showers with no accumulation expected. Of course, we will keep an eye on model trends for any possible changes.

Sunday morning will feature a hard freeze. It looks like most places will see a low between 20 and 25, with teens likely for the colder valleys and protected areas across North Alabama. Then, we begin to warm up Sunday afternoon with a high around 50 degrees.

QUICK CHANGES NEXT WEEK: A return flow begins Monday with a surge of moisture moving northward, and the GFS shows a dynamic system blowing in here Tuesday with a good chance of rain and possibly strong thunderstorms.

LATE MONTH: The pattern looks active and wet for Alabama with several periods of rain and storms; see the Weather Xtreme video for the maps, graphics, and details.

I have a weather program this morning at Northside Middle School in Tuscaloosa County; won’t be able to post an afternoon video due to travel, but I will have a few forecast notes here by 4:00. Enjoy the day, and I hope to see many of you tonight in Jasper at Storm Alert 2013…
