James Spann warns of severe weather for Alabana Thursday from Alabama News Center on Vimeo.

RADAR CHECK: We have a few spotty, light showers across central Alabama early this morning with temperatures between 57 and 64 degree s in most places. Today will be mostly cloudy and mild, with a few passing showers; afternoon temperatures reach the 70s again.

ACTIVE DAY THURSDAY: The Storm Prediction Center has introduced an enhanced risk (level 3 out of 5) of severe thunderstorms for areas west of a line from Huntsville to Birmingham to Selma to Grove Hill. The rest of the state is in a “light risk (level 2).

Here are the key messages:

• The window for strong to severe thunderstorms will open up around noon for the northwest corner of the state, with the risk spreading to the southeast during the afternoon and evening. The event will wind down a little after midnight for southeast Alabama.
• Thunderstorms across Alabama Thursday afternoon and evening will be capable of producing large hail, damaging winds and a few tornadoes. The higher tornado probabilities are across parts of west Alabama, where the SPC has defined a hatched area, meaning a strong tornado is possible (EF-2 or higher).

• Gradient winds (not related to thunderstorms) will average 15-25 mph, with gusts at times to 30 mph ahead of the storms.
• Rain amounts will be around 1 inch, with isolated heavier amounts. For now, flooding is not expected.
• Have a reliable way of hearing severe weather warnings (never an outdoor siren). The baseline is a NOAA Weather Radio; every home and business needs one. Have Wireless Emergency Alerts enabled your smartphone. Download the free ABC 33/40 Weather app.
• Know the safe place in your home or business — a small room (hall, closet, bathroom) on the lowest floor near the center, away from windows. In that safe place have helmets for everyone, air horns and hard-soled shoe.
• If you live in a mobile home, you can’t stay there if you are in a tornado warning polygon. Know the nearest shelter or business that can used as a shelter. Have transportation arranged.
• You can be a hero. If you know of a friend or loved one in a tornado warning polygon, call or text them to be sure they know the danger.
• Events like this are common in Alabama during our tornado season, which runs from November through May. There’s no need to be anxious, just be prepared and we will get through the day together just fine.

FRIDAY AND THE WEEKEND: Friday will feature a clearing sky as a much colder air mass moves into the state. Temperatures will hold in the 40s over the northern third of the state, with 50s to the south. We start the weekend with 20s early Saturday morning, followed by a high in the 50s with a sunny sky. Sunday will be another sunny day with highs in the 60s.

NEXT WEEK: The warming trend continues; we rise into the low to mid 70s during the first half of the week. A few showers are possible by Tuesday, and there will be some risk of rain statewide Wednesday, possibly into Thursday.
