Thursday will be another tranquil day across Alabama…as warm and dry conditions continue.
A cold front stretches southward across Texas and begins to make eastward progress. Showers and thunderstorms will develop along this boundary and track eastward towards the Mississippi River Valley Thursday night.
Closer to home, the high pressure ridge begins to break down some, but remains firm in place overall.
The next chance for rain in Alabama arrives late Thursday night for coastal areas of the state and on Friday for everyone as the upper level trough makes some progress to the east. The upper level ridge pushes into the Mid-Atlantic. Models indicate that the cold front stalls well back to the west as showers and thunderstorms develop along boundaries from the previous days convection.
The upper level trough will weaken and become more diffuse as it moves across the Ohio and Tennessee River valleys. Therefore the chances for severe weather are very low.
High moisture values pick up Friday night into Saturday when widespread showers and thunderstorms are expected to become likely state wide.
At this point, the rain chances appear to taper off for the northern two-thirds of the state by Sunday.
Temperatures are expected to be cooler over the weekend, largely because of the mostly cloudy and rainy conditions.
A Flash Flood Watch has been issued for the coastal counties of Alabama, from Friday night into Sunday…where extensive heavy rain may occur.
