NEXT WEEK.

ISSUED AT 1029 AM CDT FRI JUL 10 2026
SATELLITE SHOWS AN UPPER-LEVEL SHORTWAVE IS BRINGING A GROUPING
OF 2-3 MESO-VORTICIES THROUGH TODAY, LEADING TO OUR CURRENT
SITUATION WITH A BROAD CLOUD SHIELD OVER EASTERN NEBRASKA AND
SOUTHWEST IOWA. RAIN SHOULD STAY MOSTLY CONFINED TO SOUTHEAST
NEBRASKA AND SOUTHWEST IOWA, BUT CAMS DO DEVELOP A FEW ISOLATED
SHOWERS/STORMS OVER NORTHEAST NEBRASKA LATER THIS AFTERNOON
INTO THE EARLY EVENING. RAIN LIKELY CLEARS OUR AREA BY 9PM. GOOD
NEWS IS LIMITED SHEAR SHOULD KEEP SEVERE POTENTIAL LOW, BUT
STRONGER STORMS COULD PUT DOWN A FEW ISOLATED GUSTS TO 60MPH,
ESPECIALLY THIS AFTERNOON INTO THE EARLY EVENING WHEN CAPE WILL
BE HIGHEST. TEMPERATURES TODAY WILL STAY FAIRLY MILD WITH HIGHS
IN THE MID 80S.
WE'RE SEEING A SIGNIFICANT SHIFT IN THE UPPER-LEVEL PATTERN
GOING INTO THE WEEKEND, WITH HIGH PRESSURE AND RIDGING BUILDING
OVER MUCH OF THE CENTRAL CONUS. THIS WILL BE BRINGING IN AN
EXTENDED STRETCH OF HOT AND HUMID CONDITIONS WITH CHANCES OF
RAIN NEAR ZERO THROUGH MUCH OF THE EXTENDED FORECAST. WE DO SEE
A TREND IN THE LATEST LONG-RANGE GUIDANCE TO SHIFT THE RIDGE
BACK WESTWARD TOWARD THE END OF NEXT WEEK, PUTTING US BACK IN A
PATTERN OF NORTHWESTERLY FLOW. THIS WOULD ALLOW SHORTWAVES TO
BRING RAIN CHANCES BACK TO THE FORECAST STARTING FRIDAY.
HOWEVER, WITH A LOT OF TIME BETWEEN THEN AND NOW, MUCH CAN
CHANGE. CONFIDENCE REMAINS LOW IN WHEN RAIN CHANCES WILL RETURN
TO THE FORECAST.
THE BIGGEST CONCERN THROUGH THE NEXT WEEK WILL BE AN EXTENDED
PERIOD OF HOT AND HUMID WEATHER. WHILE HIGH TEMPERATURES WILL
NOT SEEM TOO EXTREME, HUMIDITY WILL BRING HEAT INDICES UP INTO
THE LOW-TO-MID 90S, ONLY INCREASING TOWARD THE END OF THE WEEK.
GUIDANCE LIKELY DOES NOT HAVE A GOOD HANDLE OF HOW MUCH "CORN
SWEAT" WILL CONTRIBUTE ADDITIONAL HUMIDITY AT THIS TIME, AND
WITH BIAS CORRECTION TOWARD RECENCY AND CLIMATOLOGY, I'D ASSUME
THAT FORECAST DEW POINTS ARE LIKELY TOO LOW, ESPECIALLY FOR DAY
THREE (MONDAY) AND BEYOND. FOR NOW, NOT MAKING ANY SIGNIFICANT
CHANGES TO DEW POINTS (AND RESULTANT HUMIDITY) IN THE EXTENDED,
BUT DON'T BE SURPRISED IF HEAT INDICES INCREASE AS WE GET CLOSER
TO EACH DAY NEXT WEEK. STILL, WE'LL LIKELY STAY UNDER "HEAT
ADVISORY" CRITERIA AT LEAST THROUGH THE FIRST HALF OF NEXT
WEEK. WITH POTENTIAL FOR ADDED MOISTURE ADVECTING IN FROM THE
GULF THURSDAY AND FRIDAY, WE COULD GET CLOSER TO CRITICAL
THRESHOLDS.
AVIATION /12Z TAFS THROUGH 12Z SATURDAY/
ISSUED AT 538 AM CDT FRI JUL 10 2026
VFR CONDITIONS ARE ANTICIPATED TO PREVAIL. A DECAYING STORM
COMPLEX HAS LARGELY BEEN REDUCED TO SHOWERS AS IT ENTERS THE
AREA FROM THE WEST. MOST OF THIS ACTIVITY WILL REMAIN SOUTH OF
INTERSTATE 80. SCATTERED RAIN SHOWERS AT LNK ARE EXPECTED WITH
A LOW (20%) CHANCE OF THUNDER. DESPITE SHOWERS, CEILINGS SHOULD
REMAIN BETWEEN FL035 AND FL045 WITH VISIBILITY GENERALLY GREATER
THAN 6SM. RAIN MOVES OFF TO THE EAST BETWEEN 15-16Z. ADDITIONAL
AFTERNOON STORM DEVELOPMENT REMAINS POSSIBLE, BUT THIS THREAT
IS LOW (20%) WITH LITTLE TO NO AVIATION IMPACTS ANTICIPATED.
WINDS REMAIN LIGHT OUT OF THE EAST TO SOUTHEAST THROUGH THE
PERIOD.
