Strong/Severe Storms Possible Later Today

ACTIVE PATTERN: We will have two opportunities for strong to severe storms across Alabama this week… the first will come this afternoon and this evening as an upper trough lifts out of the southern Great Plains. This system brought storms with large hail to parts of North Texas and Oklahoma late yesterday last night.

SPC has parts of North and West Alabama in the standard “slight risk” for severe storms this afternoon and tonight… with a “marginal risk” down to Jackson, Montgomery, and Auburn…

Surface based CAPE values (instability) are expected to climb to nearly 2,000 j/kg this afternoon, and with relatively cold air aloft hail seems to be the biggest threat; overall wind fields will be slowly weakening.

TIMING: The main risk of strong to severe storms will come from roughly 3:00 p.m. until 8:00 p.m.

THREATS: Heavier storms this afternoon and early tonight could produce large hail and strong, gusty winds. The tornado threat is very low.

RAIN: Rain amounts of 1/2 to 1 inch are expected; no flooding issues.

Away from the storms, the sky today will be mostly cloudy, and we expect a high between 76 and 79 degrees this afternoon.

TOMORROW/WEDNESDAY: A moist airmass remains over Alabama, but there is no real trigger for rain tomorrow… so we will mention just the chance of a few widely scattered showers with a mix of sun and clouds. The high will be in the upper 70s. Then, Wednesday looks warm and dry with ample sunshine and a high in the low 80s.

MORE STORMS THURSDAY: The next upper wave will bring more rain and storms to Alabama Thursday afternoon and Thursday night; SPC has much of the state in a severe weather risk on their “Day 4” outlook…

We need to get past the storms this evening to really focus on the event Thursday. Model details are not very consistent, but the overall synoptic pattern does look favorable for strong to severe storms.

FRIDAY AND THE WEEKEND: Showers should end very early in the day Friday, and the sky becomes partly sunny by afternoon. And the weekend looks nice with ample sunshine Saturday and Sunday. Highs on these three days will be in the 70s, close to seasonal averages for late March and early April in Alabama.

NEXT WEEK: Yet another wave will bring rain and storms back to Alabama by Monday night or Tuesday… see the Weather Xtreme video for maps, graphics, and more details.

STORM SPOTTER TRAINING: We will be on the road through early April offering free storm spotter classes. We need more trained spotters in Alabama; by attending you can make the severe weather warning process better. No need to register; just come with a curious mind. And, there is no age limit… kids that love weather will enjoy it. You will never look at a storm the same again. Next week we are at Oxford tomorrow (at the Oxford Civic Center) and Jasper Thursday (at the Jasper Civic Center).
