Strong Storms Across Central Alabama

| 8:23 pm July 2, 2014

Strong thunderstorms are across the middle of Alabama tonight. They are most intense over Bibb, Chilton, Dallas and northwestern Autauga Counties. They are not severe, but be prepared for very intense lightning, gusty winds and torrential rains.

The NWS Birmingham just issued a significant weather alert for several counties including:

NORTHERN AUTAUGA
SOUTHERN SHELBY
NORTHEASTERN PERRY
NORTHEASTERN DALLAS
NORTHWESTERN COOSA
CHILTON
EASTERN BIBB COUNTIES

UNTIL 900 PM CDT.

2014-07-02_20-21-03

The alert is shown in the peach polygon. Communities that will be affected include Montevallo, Maplesville, Calera, Jemsion, Thorsby and Clanton.

There are no warnings at this time.

To the north, there is still some lightning across southern Walker and Fayette Counties.

Back to the southwest, there is still a decent storm over northern Marengo County.

The storms are moving east at about 30 mph.

They are weakening slowly. The Central Alabama storms will hold together for awhile longer, but they will eventually diminish.

An Update on the Overall Situation

| 7:17 pm July 2, 2014

Here is the warning situation at 7:10:

2014-07-02_19-11-53

Thunderstorms are occurring across much of western Alabama tonight from Franklin and Marion Counties across Lamar, Pickens, Sumter, Greene, Hale, Perry and Marengo Counties.

They are moving into Winston, Fayette, Tuscaloosa and Dallas Counties.

A severe thunderstorm warning that was in effect for parts of Sumter and Greene Counties until 730 p.m. has been canceled.

A separate severe thunderstorm is over the Chilton/Coosa County border northeast of Clanton, but it is weakening. The outflow from an earlier storm that triggered the Chilton/Coosa storm has triggered a new severe thunderstorm warning for Bibb and Chilton Counties.

There are significant weather alerts for all the areas outlined in the peach color. The severe thunderstorm warnings are shown in yellow.

The storms will slowly weaken as we lose the heating of the day and instability diminishes. But it looks like they will hold together enough to make it to I-65. The Tuscaloosa area got sort of lucky as that segment of the line sort of fell apart as it approached the Druid City. The storms are a little more than 90 minutes from the Birmingham Metro, putting them in here around 9 p.m.

Trees were reported down in Lamar County along highway 96 west of Millport and in the Detroit area. That was from those high winds that were well tracked by the Columbus Doppler radar. Great job NWS Birmingham on that early warning.

A Look at Alabama’s Weather This Afternoon

| 2:40 pm July 2, 2014

An interesting weather map this afternoon across the Southeast.

Click image to enlarge and explore.

Click image to enlarge and explore.

On the visible satellite, you can clearly see tropical storm Arthur off the Northeast Coast of Florida, moving north northeast at 8 mph.

I overlaid the 500 mb height contours in green so that you can see a distinct upper level disturbance by the Mississippi River.

Radar shows intense storms along the Mississippi River north of Vicksburg. Severe thunderstorm warnings are in effect. The SPC has just issued a severe thunderstorm watch for much of Mississippi and Louisiana.

This activity will track eastward along a stalled frontal boundary that lies generally along I-59. You can see that in the top left panel. Temperatures are around 90F north ofthe front and in the middle 90s to the south.

The HRRR model indicates that the storms will weaken as they push into Alabama after 7 p.m. Here is the model reflectivity for 8 p.m.:
2014-07-02_14-30-32

But they are dissipated a couple of hours later according to the model.

We will keep out eyes on them.
