HEAVIEST SHOWERS ARE WELL INTO CENTRAL IOWA THIS AFTERNOON, BUT
AS FORECAST, LIGHT RAIN SHOWERS HAVE DEVELOPED OVER THE SOUTHERN
HALF OF THE CWA THIS AFTERNOON WITH A WEAK SHORTWAVE QUICKLY
PASSING OVERHEAD. EXPECT TO LOSE THOSE RADAR RETURNS AROUND
SUNSET. QPF IS NEGLIGIBLE.
SOUTHERLY WINDS PICK UP SPEED OVERNIGHT WITH 50-60 KNOT WINDS
AT H9. SUSTAINED SURFACE WINDS OF 15-25MPH ARE EXPECTED WITH
WIDESPREAD GUSTS OF 35 MPH.
BREEZY SOUTHERLY WINDS ARE REPLACED OVER THE COURSE OF THE DAY
ON WEDNESDAY WITH NORTHWESTERLY WINDS AS A COLD FRONT SLIDES
SOUTHEAST. IT'LL FIND ITS WAY THROUGH COLUMBUS AROUND NOON AND
THROUGH THE REMAINDER OF FAR SOUTHEAST NEBRASKA/SW IOWA AROUND
7PM. WITH PARTLY CLOUDY SKIES FORECAST, TEMPS SHOULD MANAGE
WIDESPREAD 70S WITH SOME 60S RESERVED FOR THE SOGGIEST AREAS OF
THIS MORNING. NBM WAS OVERZEALOUS IN ITS POPS ALONG THIS FRONT
THROUGH WEDNESDAY'S FIRST HALF, SO I PUSHED THEM CLOSER TO
20-25% UNTIL 4PM- ISH DURING THE DAY'S MAXIMUM HEAT. WITH THE
STEEP LAPSE RATES FORECAST, SOME THUNDER IS EXPECTED FOR AREAS
ALONG AND SOUTH OF I-80 THOUGH SEVERE WEATHER CHANCES ARE
NEGLIGIBLE ON THIS SIDE OF THE KANSAS STATE LINE.
THE STALLED FRONT MAY HELP INITIATE MORE SHOWER ACTIVITY ON
THURSDAY AFTERNOON AS A LEE SFC TROF PUSHES ALONG THE BOUNDARY.
FORECAST SOUNDINGS SUGGEST ENOUGH SHEAR AND INSTABILITY TO
PRODUCE STRONG TO SEVERE STORMS.
EXTENDED FORECAST
REGULAR CHANCES OF SHOWERS SEEM LIKE A SAFE BET (60-80%) THROUGH
THE WEEKEND AS STRONG MOISTURE RETURN DEVELOPS AHEAD OF WEST
COAST TROFING. PWAT VALUES BY SATURDAY NIGHT OF 1.5" ARE NEAR
THE 99TH PERCENTILE FOR THIS TIME OF THE YEAR, SO DESPITE NOT
YET BEING FORECAST, HEAVIER RAIN IS POSSIBLE. THE WEEK'S WARMEST
TEMPS COINCIDE WITH THE WEEKEND. SATURDAY'S HIGHS SETTLE NEAR
70F WITH ANOTHER FIVE DEGREES ADDED ATOP FOR SUNDAY.
MONDAY SEES AN UPPER LEVEL TROF DRIVING ANOTHER COLD FRONT
THROUGH THE AREA. THIS ALLOWS DRIER AND COOLER AIR TO SWEEP IN
FROM THE NORTHWEST FOR TUESDAY. THE SPC HAS ALREADY HIGHLIGHTED
SOUTHEAST NEBRASKA AND SOUTHERN IOWA AS HAVING A CHANCE FOR
SEVERE WEATHER NEXT MONDAY AHEAD OF THAT COLD FRONT.

ISSUED AT 654 PM CDT TUE APR 7 2026
SOME LINGERING SCT/BKN MVFR-LEVEL CLOUDS WILL PUSH OUT EARLY IN
THE PERIOD. VFR CONDITIONS ARE EXPECTED THEREAFTER WITH MOSTLY
PASSING MID-LEVEL CLOUDS. EXPECT SOUTHEASTERLY WINDS OVERNIGHT
GUSTING 20-25 KTS ALONG WITH SOME LOW LEVEL WIND SHEAR
(SOUTHERLY TO SOUTHWESTERLY AT 50-55 KTS AROUND 1500 FT AGL).
SURFACE WINDS WILL BECOME SOUTHWESTERLY WEDNESDAY MORNING WITH
GUSTS OF 25-30 KTS. BY LATE MORNING/EARLY AFTERNOON, A WIND
SHIFT WILL WORK THROUGH THE AREA, WITH WINDS BECOMING
NORTHWESTERLY AND WEAKENING A BIT.
