UPDATE
ISSUED AT 338 AM CDT THU SEP 3 2026
THE HEAT ADVISORY FOR SOUTHERN AND EASTERN PORTIONS OF OUR AREA HAS
BEEN EXTENDED THROUGH SATURDAY AS CONFIDENCE HAS INCREASED THAT HEAT
INDICES WILL REACH CRITERIA. AFTERNOON HEAT INDEX VALUES WILL PEAK
IN THE UPPER 90S-MID 100S THROUGH THIS TIME FRAME. HIGH TEMPERATURES
WILL PEAK IN THE MID 90S-MID 100S FOR THE ENTIRE AREA WITH LOWS ONLY
DROPPING TO THE UPPER 60S-MID 70S WITH THE HIGHEST TEMPERATURES
OCCURRING WITHIN THE HEAT ADVISORY. CHANCES FOR PRECIP WILL
REMAIN LOW (<10%) THROUGH THURSDAY AND THE DAYTIME ON FRIDAY.
THE RIDGING PATTERN OVER THE PLAINS PERSISTS THROUGH THE WEEKEND
UNTIL THE TROUGH IN THE NORTHWEST FINALLY STARTS TO PROGRESS
EASTWARD. THE RIDGING KEEPS CONDITIONS ROUGHLY THE SAME UNTIL THE
PATTERN SHIFTS. UPPER LEVEL HEIGHTS FINALLY START TO DROP SLIGHTLY
ON SUNDAY ALLOWING SOME MARGINALLY COOLER TEMPS, THOUGH HEAT INDICES
IN THE LOW 90S-LOW HUNDREDS WILL STILL BE AROUND THROUGH THE EARLY
PART OF NEXT WEEK. HIGH TEMPS REMAIN IN THE UPPER 80S-UPPER 90S
THROUGH TUESDAY.
AS THE UPPER LEVEL PATTERN SHIFTS, SHORTWAVES/DISTURBANCES MOVING
THROUGH THE RIDGING ALOFT WILL BRING BETTER CHANCES FOR PRECIP
BEGINNING FRIDAY NIGHT. CONFIDENCE ON LOCATION OF STORMS IS LOW AT
THIS TIME BUT CURRENT GUIDANCE SUGGESTS THAT OUR WESTERN AND
NORTHERN AREAS WILL HAVE THE BEST CHANCE (20-30%) TO RECEIVE PRECIP
PRECIP THROUGH THE EARLY PART OF NEXT WEEK.
DISCUSSION
ISSUED AT 122 PM CDT WED SEP 2 2026
THE MAIN CHANGE TODAY WAS THE ISSUANCE OF A HEAT ADVISORY FOR
THE SOUTHEAST PART OF THE FORECAST AREA (STOCKTON, KS TO YORK,
NE) FOR TODAY THROUGH FRIDAY. AFTERNOON HEAT INDEX VALUES MAY
APPROACH 105 DEGREES IN SOME AREAS, AND OVERNIGHT LOWS WILL BE
NEAR RECORD WARMTH (MID 70S). RAIN CHANCES REMAIN VERY LOW
THROUGH THURSDAY, ALTHOUGH A ROGUE SHOWER OR STORM CANNOT BE
RULED OUT LATE TONIGHT INTO THURSDAY MORNING (5% CHANCE).
THE HEAT POTENTIAL FOR SATURDAY IS A BIT MORE UNCERTAIN,
BECAUSE A FEW SHOWERS/THUNDERSTORMS RETURN TO THE FORECAST LATE
FRIDAY NIGHT. LINGERING CLOUD COVER COULD KEEP TEMPERATURES A
BIT COOLER ON SATURDAY, BUT IF THESE DON'T MATERIALIZE THEN IT
IS POSSIBLE THAT THE HEAT ADVISORY WILL BE EXTENDED.
LOW CHANCES FOR THUNDERSTORMS CONTINUE THROUGH THE HOLIDAY
WEEKEND AS A SERIES OF UPPER DISTURBANCES ARE EJECTED FROM AN
UPPER LOW OVER THE PACIFIC NW. TIMING WILL GENERALLY FAVOR THE
OVERNIGHT HOURS, BUT CONFIDENCE IN EXACT DETAILS REMAINS LOW AT
THIS RANGE. THE AFOREMENTIONED UPPER LOW WILL WEAKEN THE UPPER
RIDGE THAT HAS BEEN RESPONSIBLE FOR THE RECENT ROUND OF HEAT.
THIS WILL RESULT IN SLIGHTLY COOLER (BUT STILL ABOVE-NORMAL)
TEMPERATURES THROUGH THE MIDDLE OF NEXT WEEK.
