Area Forecast Discussion
National Weather Service Birmingham AL
139 PM CST Mon Jan 22 2018

.DISCUSSION...

A line of showers/storms along a pre-frontal trough continues to
push E across Central Alabama this afternoon. Noticing an overall
weakening trend in the line, especially on the northern side,
over the past few hours. Although shear is present, instability
has been lacking...which has helped keep the severe threat only
marginal at best. An isolated strong to severe storm remains
possible across the SE counties, roughly along and south of the US
Hwy 80/I-85 corridor, through 7 pm this evening.

The actual cold front is just west of Tupelo, MS, and will be
passing through the forecast area later today/tonight. Rain
chances will continue to end from W to E, with all areas rain-free
by midnight. Look for post-frontal clear skies overnight with lows
in the upper 30s N and low 40s elsewhere.

No changes made to the long-term forecast. High pressure will
dominate the weather across the Deep South for the remainder of
the work week with the next chance of rain coming over the weekend
as the next upper trough approaches from the west.

few embedded thunderstorms moving eastward through Central
Alabama. This activity will affect all terminals with ceilings
and visibilities mainly in MVFR range, perhaps a transient
