Thanks to a weak surface front that moved through Central Alabama last night, temperatures will be running about 5-10 degrees cooler than highs on Tuesday. That front has stalled out over the central part of the state. Skies at the midday hour are mostly cloudy across much of the area, with a little less cloud cover in the southern locations in Central Alabama. There are a few scattered light showers out there mainly east of I-65 and south of I-20. These are moving off to the east.
For the remainder of the day across the area, the sky will be mostly cloudy and a little light rain is possible in spots, especially in the northeastern 2/3rds of the area, but most of the day will be dry. Afternoon highs will be in the mid 60s to the mid 70s across the area from north to south. Showers will be on the increase tonight, and a few thunderstorms will be possible as well. The risk of rain is small in the southeast, and increases as you move northwest. Lows will be in the lower 50s to the lower 60s across the area.

Birmingham’s Climatology And Records
The normal high for January 18th is 52, while the normal low is 32. The record high for today was set back in 1929 at 76 degrees. The record low was set back in 1977 at 6 degrees.
An Active Thursday Possible
The Storm Prediction Center has a “marginal” risk of severe storms for a decent part of Alabama tomorrow afternoon and into the early, pre-dawn hours on Friday. An upper trough will approach from the west tomorrow while the current surface front over Central Alabama lifts northward during the day, putting the state in an unstable airmass.
Fortunately, forecast soundings are fairly saturated. You usually need dry air in the mid levels for a big severe weather threat (the best convective instability occurs when dry mid-level air advects over warm and moist air in the lower troposphere).
The main window for strong to severe storms will come from about 4:00 PM tomorrow through 2:00 AM Friday, with the main threats including damaging straight line winds and small hail, although an isolated, brief tornado can’t be ruled out. Rain amounts of around one inch are likely. There could be some minor flooding issues, but major flash flooding is not expected. As always, be sure you have a way of getting severe weather warnings in the event they are needed tomorrow night.

On This Day In Weather History: 1988
A storm in the southwestern U.S. produced a 15 to 20 foot surf along the southern coast of California resulting in more than fifty million dollars damage. A small tornado in Orange County CA lifted a baseball dugout fifteen feet into the air and deposited it in the street, 150 yards away. The same storm also produced 26 inches of snow at Duck Creek UT.
