Warm Days For Alabama; Tropics Remain Active

| September 18, 2017 @ 7:01 am

SUMMER HANGING ON: The “official” end of summer is four days away; it happens at 3:02p CT Friday when the sun is directly over the equator, the autumnal equinox. We have some fairly routine late summer weather this week with warm afternoons, high humidity, and the risk of “scattered, mostly afternoon and evening showers and thunderstorms”.

Showers/storms will be most numerous over the southern half of the state today and tomorrow; a decent part of North Alabama will be dry over the next 48 hours. Highs today and tomorrow will be in the 87-90 degree range.

Scattered showers and thunderstorms will increase statewide Wednesday through Friday as moisture deepens. The best chance of showers will be from about 12:00 noon through 8:00 p.m… otherwise we will forecast a mix of sun and clouds with a high in the mid to upper 80s.

THE ALABAMA WEEKEND: Warm, humid weather continues thanks an upper ridge; expect a partly sunny sky Saturday and Sunday with the continued threat of “scattered, mostly afternoon and evening showers and thunderstorms”. Highs over the weekend will be in the mid 80s.

NEXT WEEK: Not much change for the first half of the week, but medium range model guidance suggests we should get into some cooler, drier continental air in about 10-15 days as we get into October.

TROPICS: Out in the eastern Atlantic, Lee is a tropical depression that is in the process of becoming a remnant low. No worries there.

Closer in, we have Jose and Maria to discuss.

JOSE: Jose doesn’t look especially healthy on satellite images this morning; it is 270 miles east/southeast of Cape Hatteras, NC, and is packing sustained winds of 85 mph. While the center is expected to remain offshore, it will bring potential for tropical storm force (39 mph or higher) winds to the upper Atlantic coast through mid-week, along with dangerous surf and rip currents…

A tropical storm warning is in effect from Fenwick Island, DE to Cape Cod, MA.

MARIA: Hurricane Maria continues to grow stronger; it is now packing sustained winds of 110 mph, and is currently about 85 miles east of Martinique in the Leeward Islands. Maria is expected to be a major hurricane (category three or higher) very close to Puerto Rico Wednesday.

The hurricane will begin to gain latitude later this week, and confidence is high that it will not enter the Gulf of Mexico. For now it is too early to determine the threat to the Bahamas or the U.S. East Coast.

Interesting to note there is a chance that Maria could impact Jose (if it is still around) in 5-10 days off the U.S. Atlantic coast, with potential for the Fujiwhara effect… a case where they would orbit cyclonically (counterclockwise) about a point between the two systems.
