Cold Front Arrives Very Early Tomorrow Morning

| September 21, 2021 @ 3:19 pm

RADAR CHECK: We have scattered showers and thunderstorms in progress across Alabama this afternoon… a few of the stronger storms are producing heavy rain as they move to the east. Otherwise, there is a mix of sun and clouds with temperatures mostly in the 78-83 degree range. The average high for Birmingham on September 21 is 85.

Showers and a few storms will remain possible tonight ahead of a strong cold front, but no severe storms are expected.

FALL ARRIVES: Tomorrow is the first official day of autumn; the equinox comes at 2:20p CT tomorrow… we will have approximately 12 hours of daylight and 12 hours of darkness. And, right on time, the first good cold front of the season arrives early tomorrow morning. Showers will end for most areas before 7:00 a.m… the sky becomes mostly sunny with a stiff north breeze of 10-20 mph, gusting to 25/30 mph at times during the afternoon hours. Humidity levels will drop steadily during the day, and the high will be in the mid 70s.

We are looking at perfect fall weather Thursday through the weekend with sunny pleasant days and clear cool nights. Lows early Thursday and Friday morning will drop into the 45-55 degree range… easily the coolest air so far this season. The high Thursday and Friday will be in the mid to upper 70s, followed by low 80s over the weekend.

NEXT WEEK: Dry weather continues Monday and Tuesday with highs in the 81-85 degree range; moisture levels rise over the latter half of the week with some risk of showers returning to the state, but at the moment it looks like rain amounts will be fairly light. See the Weather Xtreme video for maps, graphics, and more details.

TROPICS: Tropical Storms Peter and Rose in the Atlantic are weak and disorganized, and won’t impact any land area. The remnants of Odette in the North Atlantic are being monitored for possible redevelopment, but if that happens it will remain far from land. And, Invest 98L in the eastern Atlantic has a high chance of becoming a tropical depression or storm over the next two days as it moves to the west/northwest, but it will turn north well before reaching the U.S.

The Gulf of Mexico remains very quiet, and tropical storm formation is not expected there for the next seven days.

ON THIS DATE IN 1938: A powerful hurricane struck Long Island and Southern New England. This Category 3 Hurricane was traveling at 47 mph when it made landfall near Bellport, New York. This storm caused at least 600 deaths and left approximately 63,000 homeless.

ON THIS DATE IN 1989: Hurricane Hugo made landfall on Isle of Palms, South Carolina as a Category 4 hurricane. This storm brought strong winds to many areas of South Carolina. In Downtown Charleston, sustained winds of 87 mph were reported; along with gusts of 108 mph.
