Highs tomorrow will reach the upper 80s to near 90. 12 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. 86/Martin && .LONG TERM...
