DISCUSSION
ISSUED AT 1226 AM CDT MON APR 20 2026
NOW THROUGH SUNDAY...
THROUGH WEDNESDAY, A DEEP UPPER LEVEL TROUGH OVER THE EASTERN
CONUS MOVES OFF AS A RIDGE THAT HAS BUILT NORTH OVER THE ROCKIES
SHIFTS EAST TO OVER THE MISSISSIPPI RIVER BY WEDNESDAY NIGHT.
GUIDANCE IS ADVERTISING SEVERAL SHORTWAVE IMPULSES PASSING OVER
THE SOUTHEAST THROUGH THE PERIOD, BUT WITH MOISTURE RETURN SLOW AS
A SURFACE RIDGE ORGANIZES OVER THE SOUTHEAST, AM NOT EXPECTING
MORE MORE THAN AN INCREASE IN MID/UPPER LEVEL CLOUDS. WITH
TEMPERATURES RISING INTO MID WEEK, BUT NOT MOISTURE LEVELS, LOW
RELATIVE HUMIDITY LEVELS WILL BE AN ISSUE WITH FIRE WEATHER
CONCERNS. MORE ON THAT BELOW. BACK TO TEMPERATURES, HIGH
TEMPERATURES IN THE UPPER 70S TO NEAR 85 RETURN TO THE FORECAST
AREA TUESDAY AND WEDNESDAY. LOW TEMPERATURES SEE AN UPTICK INTO
THE MID 50S TO AROUND 60 FOR TUESDAY AND WEDNESDAY NIGHTS.
THE UPPER RIDGE OVER THE MISSISSIPPI RIVER CONTINUES TO SHIFT EAST
THE LATTER HALF OF THE WEEK THROUGH THE WEEKEND, ALLOWING
SHORTWAVE ENERGY TO PASS CLOSER AND CLOSER TO THE SOUTHEAST.
ULTIMATELY, A WEAK SURFACE FRONT PUSHES SOUTH OVER THE SOUTHEAST
IN THE COMING WEEKEND IN RESPONSE. COMBINED WITH ONSHORE FLOW
BRINGING INCREASED GULF MOISTURE INLAND, PRECIPITATION RETURNS IN
THE COMING WEEKEND. HIGHEST POPS ARE EXPECTED TO BE CLOSER TO THE
FRONT, READ OVER THE NORTHERN HALF OF THE FORECAST AREA.
SUBSIDENCE FROM THE UPPER RIDGE WILL HELP TO KEEP TEMPERATURES
ABOVE SEASONAL NORMS.
OFFSHORE FLOW LASTS INTO TUESDAY, KEEPING THE RIP RISK LOW INTO
THE COMING WEEK. THE RETURN OF ONSHORE FLOW MID WEEK WILL BRING
BACK INCREASED SWELL TO AREA BEACHES AND A RISE IN THE RIP CURRENT
RISK TO MODERATE TO HIGH THE LATTER HALF OF THE WEEK. /16
