Heads up, West Alabama. Tonight as a front pushes through, we can expect some thunderstorms within a squall line. This line isn't expected until later tonight. However, the NWS Storm Prediction Center has issued a Tornado Watch to our west including much of Mississippi, Tennessee, and parts of Arkansas. Severe storms require instability to be present in the atmosphere. Instability is caused by warm air masses usually fed by daytime heating. Because the storms are expected to roll through tonight, we lose a lot of the day time heating by the time the storms arrive; therefore, the storms will be weaker and less structured. HOWEVER, we will maintain a slight, very slight, risk for severe thunderstorms tonight that are unlikely to produce tornadoes. Tomorrow leads to a different story. Tomorrow we will face a greater possibility of severe weather than this evening. Day time heating will feed the instability, setting the stage for severe weather to develop. The NWS SPC will not issue a watch area until they feel that one is necessary, so do not be surprised if you do not hear of a watch until tomorrow morning/midday.
We will be monitoring the system throughout the evening tonight and day tomorrow, and will keep you updated as weather unfolds. If you would like to join our email alert system, please email us at bamauams@gmail.com and tell us you'd like updates. We currently email 115+ people as weather occurs.
