DISCUSSION
ISSUED AT 109 PM CDT SUN MAY 3 2026
TONIGHT THROUGH SATURDAY NIGHT:
SURFACE HIGH PRESSURE CONTINUE ACROSS THE AREA TONIGHT THROUGH
MONDAY. ANOTHER COOL NIGHT IS ON TAP FOR TONIGHT, WITH LOWS RANGING
FROM THE MID 50S IN THE WEST TO AROUND 50 IN THE EASTERN PORTIONS OF
MISSISSIPPI. THE SURFACE HIGH WILL CONTINUE TO SHIFT TO THE EAST
TONIGHT THROUGH WEDNESDAY AND THIS WILL ALLOW FOR SOUTHERLY FLOW TO
INCREASE AND THUS EXPECT WARMER TEMPERATURES. HIGHS ON MONDAY WILL
CLIMB TO AROUND 80 DEGREES ACROSS THE AREA. TEMPERATURES WILL
CONTINUE TO CLIMB ON TUESDAY, WITH THE DRY WEATHER CONTINUING.
CHANGES ARE ON THE WAY ON WEDNESDAY AS A COLD FRONT DROPS DOWN INTO
THE NORTHERN MISSISSIPPI.
MOISTURE WILL INCREASE OUT AHEAD OF THE FRONT, WITH SHOWERS/STORMS
DEVELOPING WEDNESDAY AFTERNOON ACROSS MOST OF THE AREA. WITH
SUFFICIENT MOISTURE, INSTABILITY AND SHEAR, A SLIGHT RISK HAS
BEEN INTRODUCED AND THIS IS ALREADY BEING ADVERTISED ON OUR SITE.
HEAVY RAINFALL WILL ALSO BE A FACTOR WEDNESDAY AND WEDNESDAY NIGHT
AS THE BOUNDARY SLOWLY DROPS SOUTHEAST ACROSS THE AREA. DEPENDING
ON WHICH GLOBAL MODEL YOU LOOKS AT, SHOWERS MAY CONTINUE TO BE
POSSIBLE ACROSS THE SOUTHERN PORTIONS OF THE AREA THURSDAY INTO
THE WEEKEND, AS THE BOUNDARY HANGS UP ALONG THE COAST. /15/
