Previous short-term discussion:
(This afternoon through Tuesday)
Issued at 1156 AM CDT MON MAY 20 2024

A large ridge over the East CONUS will support a period of warm and
dry weather. The mid-level ridge axis extends from the Lower MS Valley
northeast into New England producing northwest flow aloft. The
surface ridge is extending down the spine of the Appalachians
producing a light easterly surface wind across the area. Some weak
surface convergence may kick off a shower or two in the west this
afternoon where a field of cu has developed, but mostly sunny
skies will be the story for the next couple of days with highs in
the mid to upper 80s. Clear and mild tonight with lows in the 60s,
and a small chance of some patchy fog early tomorrow morning.

.LONG TERM...
(Tuesday night through next Sunday)
Issued at 222 PM CDT MON MAY 20 2024

Upper ridging over the northern Gulf of Mexico will keep rain free
conditions across Central Alabama Wednesday and into Thursday. The
northern edge of the ridge will begin to weaken on Friday as an
upper level short wave trough tracks along the southern fringe of
the westerlies. This will produce sufficient lift for scattered
convection across the northern half of Alabama. Once this upper
impulse slides east of Alabama, the ridge could ease back
northward and result in lower rain chances on Saturday. Above
normal temperatures during this period with highs in the upper 80s
to lower 90s.
