Gulf of Mexico: Friend or Foe for Rain Fans

The Gulf of Mexico can be the friend as well as the enemy of wet weather systems for Central Alabama, and so far it has been the enemy of this one. I know, I know. You wet weather fans have heard it before. The Gulf of Mexico moisture was cut off by convection along the coast. But this time it is more a factor of waiting on the front to move north as the upper trough over the western Gulf of Mexico moves only grudgingly to the east and we wait on a surface low to form to our south.

NEVER FEAR: Rain is on the way, but amounts will be on the lighter side it appears. That’s not good news, since we continue to be dry across Central Alabama. Much of the area has received less than 75% of its average rainfall over the past 60 days. And now drought conditions have crept into a large part of the area as well, especially from Jefferson and Shelby Counties back to Bibb County then eastward to Chambers County.

A CHECK OF RADARS LATE THIS AFTERNOON: Shows that showers were trying to organize along the I-85 corridor in East Central Alabama. Others formed at peak heating from Bibb down through Marion Counties, but those have since mostly fallen apart. It now appears that there will be chances of scattered mainly light showers from the band near I-85 through the evening hours with a better area of rain developing over South Central Alabama after midnight and pushing into Georgia as a surface low forms over the northeastern Gulf.

This means the heaviest rainfall will be over South Central and Southeast Alabama and into southern Georgia.

Overnight lows tonight will be in the 60s with highs tomorrow probably limited to the 70s with a considerable clouds and a few leftover showers.
