HEATING UP: The warmest temperature so far this year, based on data from the Birmingham Airport, is 87 degrees, measured on April 10. A decent chance we beat that today; the GFS and the NAM are printing a high of 88 this afternoon, and tomorrow a 90 degree high is a real possibility for the first time in 2013. An upper ridge should keep most of Alabama rain-free today and tomorrow with a partly to mostly sunny sky; any showers will be confined to the region near the Georgia border.
TO THE WEST: Another significant severe weather event is expected today, with SPC defining a “moderate risk” of severe weather from far North Texas, through the eastern half of Oklahoma, into Northwest Arkansas and Southwest Missouri. A slight risk extends as far north as the Great Lakes. Like yesterday, a few tornadoes are likely, along with storms with large hail and damaging wind.
The risk creeps eastward tomorrow, with the standard “slight risk” from East Texas to the Great Lakes, but no part of Alabama is in the risk tomorrow as our weather should remain dry.
WEDNESDAY/THURSDAY: We will bring in the chance of scattered showers and storms for all of Alabama, but the main dynamic support will weaken and lift well north of here, so severe storms are not expected in our state. A shower or two is still possible on Thursday as a cold front moves through the state. Rain amounts Wednesday and Thursday should be generally one-half inch or less, and additional flooding issues are not expected (East Alabama had major flash flooding Saturday morning, and the ground is saturated there).
FRIDAY AND THE WEEKEND: These three days looks delightful. Sunny warm days, fair cool nights. Highs in the 80s, lows in the 60-65 degree range, although cooler spots should visit the 50s early Friday and Saturday morning. Humidity levels will be lower thanks to continental air.
LONG RANGE: Still no sign of any organized severe weather issues in Alabama through the end of May. And, just for fun, the GFS shows a tropical storm in the Gulf of Mexico in the June 3-4 time frame. This, of course, is pure voodoo, but the hurricane season does begin June 1, so it always bears watching. The most active tropical weather generally comes in August and September.
WEATHER BRAINS: Don’t forget you can listen to our weekly 90 minute netcast anytime on the web, or on iTunes. This is the show all about weather featuring many familiar voices, including our meteorologists here at ABC 33/40. We will produce this week’s show tonight at 8:30 p.m. CT… you can watch it live on our cable channel “James Spann 24/7″… or on the web here.
CONNECT: You can find me on all of the major social networks…
Look for the next Weather Xtreme video here by 4:00 this afternoon. Enjoy the day!
Storms continue to slowly build southwestward this evening over Northeast Alabama into more unstable air to the southwest, aided by a cold pool of air aloft that is edging in from Georgia.
The storm over Marshall County has gotten quite strong with torrential rain, the possibility of small hail and strong gusty winds. It is not severe, however.
It is building back into northeastern Blount County, near Snead and Susan Moore. It will push south and southeast into Etowah County, as well as eastern Blount and across much of St. Clair County. Be alert to any flooding that develops, especially given all of the extreme rains that occurred on Saturday.
Other storms have grown quickly over St. Clair County between Ashville and Springville.
Strong storms have moved out of Calhoun and Cleburne Counties, pushing into Clay and Randolph Counties. They are not severe, but also have lot of torrential rain, lightning and even the possibility of some small hail.
Strong storms continue over Northeast Alabama at this hour.
They are over Jackson and DeKalb Counties, down through Cherokee County, into Calhoun and Cleburne Counties.
Another strong storm has formed southwest of Gadsden in Etowah County.
The storms are not severe, but have plenty of lightning, torrential rains and gusty winds.
The storms are moving southeast, but the activity is trying to redevelop southwestward along the leading edge of a pool of cold air aloft that is spreading out like a big blob from the storm complex over Georgia.
The flash flood watch continues for Calhoun, Cherokee, Clay, Cleburne and Randolph Counties till 7:00 PM CDT for the heavy rainfall.
