Previous short-term discussion:
(This afternoon through Wednesday)
Issued at 1202 PM CDT TUE MAY 21 2024

Height rises are occurring this afternoon as the mid-level ridge
axis, extending from the 594dam height center over Mexico, shifts
east across Central Alabama. The surface ridge remains in place
along the East Coast. Under the effects of deep ridging,
temperatures will climb into the mid to upper 80s this afternoon
with some spots potentially hitting 90F. Mostly sunny conditions
are expected with some fair weather cu.

A weak mid-level impulse will pass across the area tomorrow bringing
some high clouds in addition to more low-level cu, but rain is not
expected. Warm conditions are expected once again with temperatures
rising from the lower to mid 60s during the morning to the upper 80s
by afternoon as flow becomes more zonal aloft.
