DISCUSSION
(THIS AFTERNOON THROUGH SATURDAY)
ISSUED AT 122 PM CDT SUN APR 19 2026
COLD AND DRY ADVECTION HAS DRIED OUT THE LOWER LEVELS, AND
SATELLITE IMAGERY SHOWS THAT THE MID/HIGH LEVEL CLOUD DECK WILL
ALSO SOON CLEAR OUT OF CENTRAL ALABAMA. THAT WILL LEAVE MOSTLY
CLEAR AND CHILLY CONDITIONS ACROSS THE AREA OVERNIGHT.
LATEST COMPUTER MODEL RUNS SHOW THE UPPER LEVEL FLOW TRANSITIONING
TO A MORE ZONAL CONFIGURATION EARLY IN THE UPCOMING WEEK, AS THIS
WEEKEND'S UPPER LOW EXITS TO THE EAST. THIS WILL ALLOW
TEMPERATURES TO MODERATE TO NEAR/SLIGHTLY ABOVE SEASONAL NORMALS.
A LACK OF SYNOPTIC SCALE LIFT (THE STORM TRACK STAYS WELL TO OUR
NORTH) AND RELATIVE LACK OF LOW LEVEL MOISTURE MEANS ANOTHER
SEVERAL DAY PERIOD OF DRY WEATHER IS ON TAP. IT IS NOT UNTIL
FRIDAY, WHEN A SUBTLE UPPER LEVEL SHORTWAVE TROUGH MOVES THROUGH,
THAT THE NEXT CHANCE OF SHOWERS AND STORMS COMES BACK INTO THE
FORECAST.
