James Spann forecast possible severe weather for Alabama on Tuesday evening from the Alabama NewsCenter on Vimeo.

DRY TODAY: With a good supply of sunshine, we are forecasting a mid-60’s high over the northern half of Alabama this afternoon; Some communities in southern Alabama will see low 70’s. Clouds will increase ahead of a storm system on Tuesday and some showers could break out later in the afternoon if moisture levels rise quickly. The high will be between 67 and 71 degrees.

MAJOR STORMS TUESDAY NIGHT: We have a chance of strong to severe thunderstorms over Alabama Tuesday night through early Wednesday morning. The Storm Prediction Center has defined an elevated risk (Level 3 of 5) for the northwest corner of the state around the Shoals; There is low risk (Level 2) as far east as Decatur, Jasper and Livingston, and low risk (Level 1) across to Fort Payne, Calera, Jackson and Mobile.

A small risk exists for southeast Alabama after 6 a.m. Wednesday.

TIMED COORDINATION: A few severe storms are possible in far western Alabama as early as 5 p.m. and 8 p.m. Tuesday, but the core threat to the state’s western counties will come from 8 p.m. to 2 a.m. Severe weather danger will shift to east and southeast Alabama before dawn Wednesday.

THREATS: Storms over western Alabama Tuesday night can produce large hail, damaging winds and some tornadoes. The threat to eastern Alabama comes primarily from strong thunderstorm winds.

WIND: Away from thunderstorms, Tuesday night’s pressure gradient winds will average 15 to 25 mph, with potential for gusts up to 40 mph in certain spots.

RAIN: Amounts of 1-2 inches are likely; Floods are not to be expected.

BE PREPARED: For most of Alabama, the prime threat will come late at night and early in the morning, which means you need a reliable way to get alerts when they’re needed. The best way is a NOAA weather radio; every home and business needs one. Make sure you have wireless emergency notifications enabled on your phone and have the free weather app ABC 33/40 installed. Know the safe place in your home and have helmets for everyone. If you live in an RV, you know the location of the nearest emergency shelter or 24-hour shop that can provide shelter, and you know the quickest way to get there. have transportation available.

There is some uncertainty as to how this event will unfold. The situation with the best chances is that a large area of ​​rain develops Tuesday night before the arrival of the best dynamic support. This could keep instability low and really reduce the risk of severe storms. But there is no guarantee and we must all be ready.

REST OF THE WEEK: Skies are clearing on Wednesday and colder air is arriving over the northern half of the state with a high in the 50’s. Most locations in northern and central Alabama will fall in the 27 to 32 range by early Thursday morning, with mid-30s for southern Alabama. Thursday and Friday will feature sunny skies; the high is in the 50’s on Thursday, followed by the 60’s on Friday.

THE ALABAMA WEEKEND: Humidity will increase and we must mention that there may be showers in the northern half of the state on both Saturday and Sunday. It doesn’t look like a major rain event at the moment and the weekend certainly won’t be a washout. Weekend highs range from 67 to 73 degrees with more cloud than sun.

NEXT WEEK: Global models are pointing to showers Tuesday through Wednesday, followed by cooler, drier air in the second half of the week. Highs are in the high 60’s and low 70’s Monday and Tuesday, then in the 50’s and 60’s Wednesday through Friday.
