SHORT TERM /THROUGH FRIDAY/
ISSUED AT 146 PM CDT THU MAY 28 2026
SURFACE HIGH PRESSURE OVER THE UPPER GREAT LAKES CONTINUES TO BRING
BOTH EAST WINDS AND DRY AIR TO OUR AREA TODAY. AS OF 1 PM,
TEMPERATURES ARE RUNNING IN THE LOWER TO MID 80S, WELL ABOVE THE
MORNING LOWS IN THE UPPER 50S TO LOWER 60S LAST NIGHT. ABOVE OUR DRY
LOW LEVEL AIR, WE ARE SEEING RATHER WIDESPREAD NON-OPAQUE CIRRUS ON
THE FAR NORTHEAST FRINGE OF THE CUT OFF UPPER AND SURFACE LOW TO THE
IN KANSAS. THIS LOW IS FAR TOO SOUTHWEST TO OFFER A CHANCE FOR RAIN
TODAY, BUT IS CLOSE ENOUGH TO BRING A LITTLE HIGH CLOUD COVER. THAT
GENERAL SET UP WILL CONTINUE TONIGHT AND FRIDAY, WITH LITTLE CHANGE
IN SENSIBLE WEATHER NOTED.
EAST WINDS, AND THIN CLOUD COVER WILL CONTINUE TONIGHT, WITH LOWS
FALLING TO THE LOWER 60S SOUTHWEST TO LOWER 50S NORTHEAST, AND A FEW
LOCATIONS UPPER 40S COULD OCCUR IN VALLEYS/DRAINAGE AREAS.
FRIDAY, A BIT THICKER CLOUD COVER IN OUR SOUTHWEST COUNTIES WILL
POTENTIALLY LIMIT HIGHS TO THE LOW 80S, WHILE LOWER TO MID 80S ARE
SEEN FARTHER NORTHEAST. A SLIGHT CHANCE FOR RAIN IS FORECAST IN THE
NORTHEAST MO COUNTIES INTO FAR SOUTHEAST IOWA. THIS WILL BE MINIMAL
IF IT FORMS, WELL UNDER 0.1" THROUGH SATURDAY MORNING IN THE SAME
AREA.
LONG TERM /FRIDAY NIGHT THROUGH THURSDAY/
ISSUED AT 146 PM CDT THU MAY 28 2026
THE PATTERN REMAINS STAGNANT INTO THE EXTENDED FORECAST AS AN OMEGA
BLOCK SETS UP, WITH SOME WEAKNESS IN THE HIGH PRESSURE INTO CENTRAL
IOWA, ALLOWING FOR 10-30% CHANCES FOR RAINFALL AT TIMES WEST.
ANY AMOUNTS APPEAR VERY LIGHT SHOULD RAIN OCCUR.
LOOKING FARTHER OUT, ENSEMBLE AND DETERMINISTIC GUIDANCE CONTINUE TO
SUPPORT THE OMEGA BLOCK TO REMAIN THROUGH THE MIDDLE OF NEXT WEEK.
THE WEST COAST UPPER LOW WILL EVENTUALLY LIFT NORTHEAST OVER MT AND
SOUTHWEST CANADA EARLY NEXT WEEK AND PROGRESS EASTWARD ALLOWING FOR
THE RIDGE TO START TO BREAK DOWN (HEIGHT FALLS). A SEMI-ZONAL FLOW
WILL RESULT WITH A FEW WAVES TRACKING OVER THE NORTHERN PLAINS AND
UPPER MIDWEST THAT COULD BRING US SOME RAIN ALBEIT NOT LIKELY
BENEFICIAL. AS A RESULT, DROUGHT CONDITIONS ARE LIKELY TO
WORSEN/EXPAND OVER THE COMING WEEKS. IN ADDITION, THE LATEST 6-10
AND 8-14 DAY PRECIP OUTLOOKS FOR THE CLIMATE PREDICTION CENTER HAVE
70-80% COMBINED PROBABILITIES OF NEAR/BELOW NORMAL PRECIPITATION
GOING THROUGH THE 1ST WEEK OF JUNE. UNFORTUNATELY, IT WILL BE A
WHILE BEFORE LIQUID GOLD (RAIN) COMES BACK INTO THE FORECAST.
PORTIONS OF OUR AREA WERE ADDED TO THE D-0 STATUS OF THE DROUGHT
MONITOR TODAY, AN EXPANDING AREA THAT WILL LIKELY WORSEN AND EXPAND
ON FUTURE OUTLOOKS.
AVIATION /00Z TAFS THROUGH 00Z SATURDAY/
