AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HASTINGS NE
414 PM CDT MON JUL 27 2026
KEY MESSAGES
- BRUTAL HEAT CONTINUES ACROSS THE AREA THROUGH THIS EVENING,
WITH SEVERAL INSTANCES TODAY WHERE HEAT INDEX VALUES WERE
SOLIDLY IN THE 115-120 DEGREE RANGE. EXTREME HEAT WARNING
REMAINS IN EFFECT UNTIL 10PM THIS EVENING.
- THUNDERSTORM ACTIVITY ALREADY ONGOING ACROSS PORTIONS OF THE
HIGH PLAINS LATE THIS AFTERNOON...STILL LOOKING AT THE
POTENTIAL FOR ACTIVITY TO GRADUALLY DRIFT EAST THIS EVENING-
TONIGHT INTO THE FORECAST AREA. HOW THE OVERALL COVERAGE ENDS
UP EVOLVING STILL HAS SOME QUESTIONS...MAY END UP BEING FAIRLY
SCATTERED IN NATURE. NOT OUT OF THE QUESTION SOME STORMS COULD
BE STRONG-MARGINALLY SEVERE...WITH WIND GUSTS NEAR 60 MPH THE
PRIMARY HAZARD.
- PERIODIC STORM CHANCES CONTINUE ON THROUGH THE MIDDLE OF THE
WEEK (MAINLY DURING THE EVENING-OVERNIGHT HOURS)...AND WE
FINALLY GET A BREAK FROM THE HEAT THE PAST FEW DAYS. HIGHS ARE
MORE IN THE UPPER 80S-MID 90S TUE-THU, WITH MID 80S-NEAR 90
FRI-SUN.
DISCUSSION
ISSUED AT 409 PM CDT MON JUL 27 2026
CURRENTLY THROUGH TONIGHT...
OUTSIDE OF THE BRUTAL HEAT AND HUMIDITY, OVERALL QUIET
CONDITIONS REMAIN IN PLACE ACROSS THE FORECAST AREA THIS
AFTERNOON. LOOKING ALOFT, UPPER AIR AND SATELLITE DATA SHOW
LITTLE CHANGE IN THE RIDGING DOMINATING THE PATTERN, CENTERED
ROUGHLY OVER THE OK/TX/CO/NM BORDER AREA...KEEPING FLOW ACROSS
THE CENTRAL PLAINS WEST-NORTHWESTERLY. AT THE SURFACE, AN
OVERALL WEAK FRONTAL BOUNDARY HAS SUNK SOUTH THROUGH THE
AREA...CURRENTLY STALLED OUT FROM WEST- CENTRAL KS NORTHEASTWARD
INTO SOUTHEAST NE. THIS BOUNDARY HASN'T DONE MUCH FOR
TEMPERATURES...WITH 3PM OBS IN THE MID 90S TO NEAR 100, BUT
SEPARATING THE MORE EASTERLY WINDS TO ITS NORTH TO THE MORE
SOUTHERN WINDS TO ITS SOUTH. NOT SURPRISINGLY, MOISTURE HAS
POOLED ALONG/NORTH OF THIS BOUNDARY...WITH NASTY DEWPOINTS IN
THE UPPER 70S TO MID 80S ACROSS MOST OF OUR NEBRASKA COUNTIES,
WHILE A LITTLE MORE MIXING IS KEEPING DEWPOINTS IN OUR SOUTH IN
THE MID 60S-NEAR 70. AS A RESULT, SEVERAL AUTOMATED SENSORS HAVE
BEEN SHOWING HEAT INDEX VALUES MORE IN THE 115-120 DEGREE RANGE
AT TIMES. OBVIOUSLY NO CHANGES MADE TO THE EXTREME HEAT WARNING
THAT REMAINS IN PLACE CWA-WIDE THROUGH 10PM THIS EVENING.
OFF TO THE WEST-NORTHWEST OVER THE HIGH PLAINS, BEEN SEEING THE
DEVELOPMENT OF SCATTERED THUNDERSTORMS THIS AFTERNOON. OVERALL
SUBTLE FORCING ALOFT, ALONG WITH UPSLOPE LOW-LEVEL FLOW TO THE
NORTH ACROSS PORTIONS OF SD AND THE FRONTAL BOUNDARY ACROSS
WESTERN KS IS HELPING WITH ACTIVITY. THE BRUTAL HEATING IS
ALLOWING FOR STEEPER LAPSE RATES AND NO SHORTAGE OF INSTABILITY
(SPC MESO PAGE SHOWING 3000-5000 J/KG OF MLCAPE ACROSS THE
REGION)...BUT DEEPER LAYER IS SHEAR IS PRETTY LOW. WINDS ALOFT
ARE NOT STRONG, SO NOT SEEING QUICK MOVEMENT WITH ANY OF THIS
ACTIVITY...MORE JUST GRADUALLY DRIFTING EAST WITH TIME.
THIS EVENING ON THROUGH TONIGHT...THERE REMAINS THE POTENTIAL
FOR SHOWERS/STORMS TO CONTINUE MAKING THEIR WAY EAST THROUGH
THE FORECAST AREA. PRECIPITATION CHANCES REMAIN PRETTY BROAD IN
NATURE...MODELS STILL SHOWING SOME VARIATION ON JUST HOW MUCH
COVERAGE THERE ULTIMATELY ENDS UP BEING. NOT OUT OF THE QUESTION
THAT A FEW OF THESE STORMS COULD BE ON THE STRONG TO MARGINALLY
SEVERE SIDE GIVEN THE LINGERING INSTABILITY...WIND GUSTS NEAR
60 MPH LOOK TO BE THE PRIMARY HAZARD, AND THE ENTIRE CWA REMAINS
IN THE DAY 1 MARGINAL RISK AREA.
MID-WEEK...
FOR THE TUESDAY THROUGH THURSDAY TIME FRAME, OVERALL NO NOTABLE
CHANGES IN THE FORECAST. MODELS SHOW LITTLE CHANGE IN THE UPPER
LEVEL PATTERN, WITH THE MAIN UPPER LEVEL RIDGE AXIS CONTINUING
TO RUN ROUGHLY THROUGH THE HIGH PLAINS. THERE REMAIN PERIODIC
CHANCES FOR SHOWERS AND THUNDERSTORMS...MAINLY DURING THE MID-
LATE EVENING AND OVERNIGHT HOURS...AS MODELS CONTINUE TO SHOW
THE POTENTIAL FOR SHORTWAVE DISTURBANCES RIDING AROUND THE EDGE
OF THE MAIN RIDGING AND SLIDING THROUGH THE AREA. PRECIPITATION
CHANCES TUE EVENING- NIGHT AND AGAIN WED EVENING-NIGHT REMAIN
GENERALLY IN THE 20-50 PERCENT RANGE...WITH MODELS THEN SHOWING
THE POTENTIAL FOR A STRONGER SHORTWAVE DISTURBANCE TO DIG
FURTHER SOUTH, WITH MORE WIDESPREAD 40-60 PERCENT CHANCES THU-
THU NIGHT. STILL PLENTY OF DETAILS TO IRON OUT WITH THE
TIMING/COVERAGE OF THOSE CHANCES.
MORE NOTEWORTHY FOR THE MID-WEEK PERIOD IS MODELS SHOWING A
BREAK FROM THE HEAT FROM THE PAST FEW DAYS. HIGHS TUE-THU ARE
FORECAST IN THE UPPER 80S-MID 90S...WITH HEAT INDEX VALUES MORE
IN THE 90S-NEAR 100...VS THE WELL ABOVE 100 FROM THE PAST FEW
DAYS.
FRIDAY AND ON...
THE FORECAST FOR FRIDAY ON INTO THE WEEKEND DRIES OUT...BUT WILL
SEE IF THAT ULTIMATELY ENDS UP PANNING OUT THAT WAY. THE UPPER
LEVEL DISTURBANCE THAT MOVES THROUGH THU-THU NIGHT LOOKS TO
GIVE THE MAIN RIDGE AXIS A BETTER PUSH BACK TO THE
WEST...LEAVING OUR AREA WITH MORE AMPLIFIED NORTH-NORTHWESTERLY
FLOW. AT THIS POINT MODELS AREN'T SHOWING MUCH IN THE WAY OF
DISTURBANCES IMPACTING THE AREA. THIS SHIFT IN THE RIDGING HELPS
KEEPS TEMPS CLOSER TO NORMAL FOR THIS TIME OF YEAR...GENERALLY
FORECAST TO RANGE FROM THE MID 80S TO NEAR 90 THROUGH THIS
PERIOD.
AVIATION /18Z TAFS THROUGH 18Z TUESDAY/
ISSUED AT 1232 PM CDT MON JUL 27 2026
FOR KGRI/KEAR AIRPORTS:
VFR CONDITIONS ARE CURRENTLY FORECAST...WITH THE MAJORITY OF
THIS TAF PERIOD EXPECTED TO BE DRY. MAIN TIMEFRAME OF CONCERN
FOR THESE POTENTIALLY SCATTERED SHOWERS/STORMS LOOKS TO BE AFTER
MIDNIGHT, CURRENTLY CARRYING AT PROB30 GROUP IN THE 08-13Z
PERIOD...SOME MODELS SUGGEST AT LEAST ISOLATED ACTIVITY COULD
CREEP INTO THE AREA A LITTLE EARLIER THAN THAT, SO CONFIDENCE IN
THE TIMING ISN'T OVERLY HIGH. KEPT THE PROB30 GROUP VFR AT THIS
POINT, BUT IF A STRONGER/HEAVIER STORM HAPPENS TO MOVE OVER THE
TERMINAL AREAS, A BRIEF REDUCTION IN CEILING/VISIBILITY WILL BE
POSSIBLE. WINDS REMAIN NORTHEASTERLY THE REST OF TODAY, CAN'T
RULE OUT AN OCCASIONAL GUST NEAR 20 MPH THIS AFTERNOON. MORE
VARIABLE WINDS WILL BE POSSIBLE LATER THIS
EVENING/TONIGHT...AGAIN ESPECIALLY IF A STRONGER STORM MOVES
THROUGH, A HIGHER GUST WILL BE POSSIBLE. FOR THE LATTER PORTION
OF THIS PERIOD AFTER SUNRISE, WINDS LOOK TO BE MORE EASTERLY.
