Here is a look at the Alabama weather situation as we approach 11:30.

Dr. Tim Coleman is preparing a thorough analysis of the morning model data and will have it up in about an hour.

A band of weakening showers extends Cullman and Blount Counties through Jefferson, Shelby, Bibb, Perry and Dallas Counties. Lightning is nearly gone, but an occasional strike as well as some moderate rain and gusty winds could be produced by these showers.

Skies are mostly cloudy over the state, but there are some breaks in the overcast over the eastern half of the area. This has allowed temperatures to warm into the upper 70s in spots like Montgomery (79F) and Alex City (79F). Instability values are going up over this area and we are already seeing development of showers and storms over Chilton, Autauga and Lowndes Counties, this activity will push northeast into Coosa and Elmore Counties.

Radars will begin to light up this afternoon over northeastern Texas into southern Arkansas as strong upper level winds approach from the west, triggering the development of a strong surface low. A very unstable, strongly sheared atmosphere will exist from eastern Texas across extreme northwestern Louisiana, southern Arkansas and into northwestern Mississippi and western Tennessee. A significant outbreak of tornadoes including long track and violent tornadoes could occur in these areas. The SPC is adding to the high risk outlook area they were already carrying from this morning, extending into into Mississippi and Tennessee.

This activity should congeal into a big mass of thunderstorms tonight that will move across western Tennessee and northern Mississippi and into Northwest Alabama during the predawn hours. These storms will produce some severe weather, as well as heavy rain.

This activity should stall out and wait for the final push from another upper level disturbance, which will come during the day tomorrow. Thunderstorms will start increasing again over North and Central Mississippi during the morning hours and fire off into Alabama. it looks like thunderstorms will rapidly become severe over North and Central Alabama during the late morning and afternoon hours.

It also looks like the parameters will be there for a significant outbreak of severe weather, including the possibility of tornadoes across our area tomorrow. Please keep monitoring the situation during the next 36 hours and stay close to a reliable source for weather watches and warnings.
