A Just After Midday Nowcast for Tuesday; Strong to Severe Storms Possible on Wednesday

| November 24, 2020 @ 1:07 pm

AS OF 1:00 PM

Skies across Central Alabama are mostly clear to sunny as it is a very nice and cool last Tuesday for the month of November. Temperatures as of the 1:00 pm roundup were in the lower 60s to the lower 70s across the area. Haleyville was the cool spot at 60 degrees while Selma was the warm spot at 70 degrees. Birmingham was at 64 degrees.

REST OF TODAY

Skies will continue to stay mostly clear through the afternoon and into the evening hours, but clouds will be on the increase from the west and northwest during the late-night and overnight hours. A few showers will be possible over the northwest corner of Central Alabama starting after the late local news time. Afternoon highs will top out in the lower 60s to the lower 70s across the area from northwest to southeast with overnight lows only dropping into the lower to mid-50s.

A FEW STRONG STORMS POSSIBLE ON WEDNESDAY

A strong cold front will be approaching Central Alabama on Wednesday and will move southeast through the area Wednesday night. There will plenty of shear and enough instability out ahead of the front that a few strong to severe storms may develop. The SPC has all of Central Alabama north of the I-85 corridor in a level 1 Marginal Risk for severe storms mainly for Wednesday afternoon through the pre-dawn hours on Thursday morning.

Timing for the threat of strong to severe storms will be from around 3:00 pm Wednesday afternoon until around 10:00 pm Wednesday night. The main threats will be from isolated damaging wind gusts up to 60 MPH and the potential for a brief tornado or two.

While it will not rain all day and you may get a good time spread of dry weather, but remember showers and thunderstorms will be likely along and west of the I-59 corridor and a good chance of showers and thunderstorms east of that. The cold front will actually stall out somewhere in between the I-59 and I-85 corridors, so we really won’t notice a difference in temperatures across the area. Afternoon highs will be in the upper 60s to the mid-70s across the area from northwest to southeast.

THE TROPICS

A non-tropical area of low pressure located a couple of hundred miles south-southeast of Bermuda has merged with a frontal system and is producing gale-force winds, along with showers and thunderstorms to the east of its center. By Thursday, the system could become separated from the front, allowing it to possibly develop some subtropical characteristics later this week while it meanders over the central Atlantic. The NHC is only giving it a 30% chance of development over the next 120 hours.

ON THIS DATE IN WEATHER HISTORY

1982: Hurricane Iwa lashed the Hawaiian Islands of Niihau, Kauai, and Oahu with high winds and surf. Winds gusting to 120 mph caused extensive shoreline damage. Damage totaled 150 million dollars on Kauai, and fifty million dollars on Oahu. The peak storm surge on the south shore was six to eight feet. It marked the first time in 25 years that Hawaii had been affected by a hurricane.
