This Hazardous Weather Outlook is for the counties served by the National Weather Service office in Birmingham.

.DAY ONE…Today and Tonight.

No hazardous weather is expected at this time.

.DAYS TWO THROUGH SEVEN…Friday through Wednesday.

The combination of high temperatures and humidity will push heat index values to around 105 degrees on Friday afternoon and again Saturday afternoon. This will occur generally west of a line from Eufaula to Alabaster to Hamilton.

Severe thunderstorms will be possible across all of Central Alabama Friday night into early Saturday morning. A line of storms with damaging winds may enter our northern counties as early as 9 PM Friday and continue southward through 5 AM Saturday. Currently the highest threat area appears to be along and northwest of Interstate 59, where widespread wind damage is possible.

Severe storms may develop again on Saturday afternoon and evening along and southeast of Interstate 59. These storms may be isolated to scattered in nature and capable of producing damaging winds, quarter size hail, and perhaps a tornado. Currently, forecast confidence in this scenario is low.

.SPOTTER INFORMATION STATEMENT…

Activation of storm spotters and emergency management may be needed on Friday night and Saturday.
