The Latest Weather XtremeVideo: Storms Return Sunday Night

HEATING UP: With a partly sunny sky today, we expect a high in the mid 80s across much of North/Central Alabama today… the average high for April 28 is 77. An isolated shower could fire up late this afternoon as the air becomes unstable, but the chance of any one spot getting wet is only about one in ten.

Both the NAM and the GFS models are suggesting a high at 90 degrees for Birmingham tomorrow; if we can achieve that level it will beat the old record high for April 29 of 89 set in 1915. We will mention a chance of widely scattered thunderstorms tomorrow afternoon and evening as moisture levels will be a tad higher. Otherwise, we expect a mix of sun and clouds tomorrow.

To the west, active storms will fire up across the ArkLaTex region tomorrow and tomorrow night, and those will move into Alabama before the weekend is over.

SUNDAY: It will be a warm and windy day; much of the daytime hours should be dry with only isolated showers. Thunderstorms will push into Alabama Sunday night ahead of a cold front, and those could pack a punch. SPC has the western quarter of Alabama in the standard “slight risk” Sunday night, with a “marginal risk” of severe weather for much of the rest of the state…

Seems like the main limiting factor for severe weather Sunday night will be the lack of surface based instability; CAPE values are forecast to be under 500 j/kg as the storms move through.

The main window for thunderstorms will come from 6:00 p.m. Sunday through 6:00 a.m. Monday. The main risk will come from strong, gusty straight line winds, although some hail is also possible. For now the threat of tornadoes looks rather low. We will keep a close eye on things over the weekend as the event gets closer.

Rain amounts of 1-2 inches are likely Sunday night; not bad news since much of North/Central Alabama is still in a drought condition.

NEXT WEEK: Monday will feature a clearing sky and cooler temperatures; the high will be in the low 70s. And, by daybreak Tuesday, upper 40s are possible. Then, the next chance of rain and storms will come late Wednesday into Thursday. See the Weather Xtreme video for maps, graphics, and more details.
