More Showers/Storms

| 10:59 pm July 3, 2015

7-3-2015 10-57-15 PM

Another round of showers and thunderstorms is moving across much of the same area that experienced a couple of rounds of storms this afternoon.

Showers and storms extend from the Alabaster area down through Calera, Maplesville and Marion.

Other storms have formed ahead of this main activity along US_80 from Demopolis to Selma and Montgomery.

Lots of lightning, gusty winds and heavy rain, but the storms are not expected to become severe.

Showers and storms are expected to be common through the morning hours in about the same areas.

Update on the Storms

| 8:00 pm July 3, 2015

2015-07-03_19-58-31

Four areas of storms to worry about tonight:

1. Chilton County storms are quite strong, but not severe. Lots of lightning and heavy rain as well as gusty winds. They are straddling I-65 around Lomax and Clanton. They will be approaching Lake Mitchell shortly.

2. Montgomery Area: strong storms with lots of lightning in the Montgomery area.

3. West Central Alabama: A couple of isolated strong storms are over northwestern Tuscaloosa County and northwestern Greene County. The Tuscaloosa storm will affect areas well north of the City of Tuscaloosa, the University of Alabama and Northport, mainly affecting rural areas near and around Moores Bridge Samanatha as it moves east southeast. This storm will stay just north of Lake Tuscaloosa. The Greene County storm will cross I-59 around Eutaw and Knoxille before 8:15.

4. Approaching Pickens and Lamar Counties: Strong to severe storms in eastern Mississippi from Amory to Aberdeen to West Point will be reaching West Alabama’s Lamar and northern Pickens Counties starting around 815 p.m. The storms should reach Vernon before 8:30 and Millport before 8:45.

The storms are not severe at this time, but have the potential to become severe thanks do some fairly significant wind shear for summer. All of the storms will be capable of deadly lightning, very heavy rain and strong gusty winds.

The polygons in peach are Significant Weather Alerts from the NWS.

Severe Thunderstorm Watch in Our Future?

| 6:20 pm July 3, 2015

7-3-2015 6-17-47 PM

Strong thunderstorms have developed afternoon across Central Alabama. One storm that has moved out of Chilton County and is now crossing Coosa County around Lake Mitchell has produced hail to 1.5 inches in diameter, including numerous reports of large hail back in Bibb County and in the Jemison area. Numerous reports of 1 inch hail were received from around Jemison. Some trees were also reported down in Bibb County.

0.72 inches of rain was reported in Thorsby in 20 mins according to @nightnurse24 (Tracy McDaniel). Justin Gentry reported 0.71 inches in Jemison. Back in Tuscaloosa County, Wallace Williams reported 0.72 inches at Cottondale.

This storm is a little weaker now, but a trailing storm is catching up to the first storm and the two are about to merge over Coosa County west of Rockford.

Other storms are over northern Hale and much of Bibb County at this hour. They will be moving across much of Shelby County over the next couple of hours. These storms are not as strong as the Chilton/Coosa County storms for now.

The storms are tapping an instability-rich airmass to the south of an outflow boundary that settled into North Central Alabama this morning. South of I-20, CAPE values are over 2,000 j/kg. The storms should continue to be strong for the next few hours thanks to decent winds aloft at about 18,000 that are blowing across Central Mississippi and Central Alabama. These winds of up to 50 mph are producing a decent amount of speed shear that is allowing our storms to lean over and not choke on their own updrafts like garden variety summer storms do.

This speed max will be shifting eastward across Alabama this evening. As it does, it will allow storms to continue strong. A complex of thunderstorms back in western Mississippi and additional strong to severe storms over eastern Mississippi will track west to east across the state through the evening and overnight.

A severe thunderstorm watch may be issued for Central Alabama a little later.

Damaging winds and some hail will be the severe threats, along with very heavy rain and intense lightning.

Stay weather aware tonight, especially if you have outdoor holiday plans.

Showers and thunderstorms continue forming over North-Central Alabama this afternoon. Storms are also affecting Southern Walker County and Cullman Counties, moving eastward toward Blount and northern Jefferson County. A Significant Weather Alert has been issued for Blount County.

These storms will affect northern portions of the Birmingham Metro area over the next hour with the threat of lightning, heavy rain, and gusty winds.

All across North Central Alabama, the airmass is moderately unstable with CAPE values over 3,000 joules/kg. There is a nice instability maximum from Walker County down through the Birmingham Metro where those CAPE values are over 3,500 joules. This energy will fuel the strong storms. These storms could increase to become more severe through the afternoon hours. All storms will produce deadly lightning, heavy rain and gusty winds.

The line of thunderstorms passing through Nashville extends down the Tennessee Valley and into Northern Alabama, rolling toward Decatur, Athens and Huntsville. A Severe Thunderstorm Warning has just been issued for Limestone and Madison Counties.

The Severe Thunderstorm Watch continues for North Alabama through 6:00 p.m. Further south, the SPC maintains their standard slight risk severe weather forecast as far south as Vernon, Alabaster, Sylacauga and Lineville. Damaging winds is the main threat. The North Alabama storms will have some small hail.

A cluster of storms is moving through Fort Payne, Centre, and Albertville. Winds gusted to 43 mph at Albertville at 1:15 p.m.
