DISCUSSION
ISSUED AT 158 PM CDT TUE APR 28 2026
RADAR THIS AFTERNOON SHOWS AREAS OF SHOWERS MOVING ACROSS EASTERN
NEBRASKA AND WESTERN IOWA. EXPECT MAYBE A FEW HUNDREDTHS OF AN INCH
OF PRECIPITATION WITH THESE SHOWERS FOR THOSE LUCKY ENOUGH TO GET
ANYTHING. DESPITE THE DECENT LOOKING PRECIPITATION SHOWING UP ON
RADAR, WE HAVE HAD VIRGA (RAIN EVAPORATING BEFORE REACHING THE
GROUND) IN SOME LOCATIONS TODAY. THIS WILL LIMIT SOME POTENTIAL FOR
ACCUMULATIONS.
HEADING INTO TONIGHT, A FROST ADVISORY HAS BEEN ISSUED FOR PORTIONS
OF EASTERN NEBRASKA. LOW TEMPERATURES ARE EXPECTED TO FALL INTO THE
LOW TO MID-30S OVERNIGHT WITH WINDS UNDER 5MPH IN MANY AREAS. CLOUDS
ARE EXPECTED TO DECREASE ACROSS THE ADVISORY AREA, BECOMING MOSTLY
CLEAR. THE MAIN QUESTION WITH THE FROST POTENTIAL TONIGHT WILL BE
HOW QUICKLY THE CLOUDS MOVE OUT. AREAS THAT HOLD ONTO CLOUD COVER A
LITTLE LONGER THAN EXPECTED MAY NOT RECEIVE ANY FROST. HELD OFF FROM
PUTTING FOG INTO THE FORECAST FOR NOW AS CLOUD COVER MAY LIMIT SOME
POTENTIAL.
WEDNESDAY, SURFACE HIGH PRESSURE MOVES INTO THE REGION BRINGING
SOME SLIGHTLY WARMER TEMPERATURES. EXPECTED HIGHS WILL WARM
INTO THE UPPER 50S TO MID-60S WITH WEST WINDS APPROACHING
5-10MPH.
A COLD FRONT DROPS IN FROM THE NORTH ON THURSDAY, USHERING IN SOME
SLIGHTLY COOLER AIR. TEMPERATURES WILL RANGE FROM THE MID-50S TO LOW
60S FOR AREAS ALONG AND NORTH OF I-80 WITH MID-60S FOR THE I-80
CORRIDOR AND LOCATIONS SOUTH OF IT. THERE WILL BE ANOTHER CHANCE FOR
A FEW SHOWERS/STORMS ALONG AND AHEAD OF THE FRONT THURSDAY
AFTERNOON. AREAS OF FROST WILL BE POSSIBLE THURSDAY AND FRIDAY
MORNINGS.
HEADING INTO THE WEEKEND, EXPECT DRY AND WARM CONDITIONS AS A RIDGE
SHIFTS EAST, PUTTING US UNDER NORTHWEST FLOW. EXPECT A GRADUAL
WARMING TREND WITH HIGHS REACHING THE 70S BY SUNDAY AFTERNOON.
AVIATION /00Z TAFS THROUGH 00Z THURSDAY/

SHOWERS ARE DISSIPATING ACROSS THE AREA SO HAVE REMOVED THEIR
MENTIONS KOMA AND KOFK DUE TO PROBABILITIES LESS THAN 30%. HAVE
MAINTAINED VCSH AT LNK UNTIL 9PM. OTHERWISE EXPECT WINDS TO
CONTINUE TO SLOW AND BECOME LIGHT AND VARIABLE OVERNIGHT (MOSTLY
NORTHWEST). FOG IS EXPECTED TO IMPACT CENTRAL NEBRASKA BUT STAY
WEST OF EASTERN NEBRASKA TAF SITES.
