AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HASTINGS NE
500 AM CDT FRI AUG 7 2026
KEY MESSAGES
- AREAS OF PATCHY FOG DEVELOPMENT IS POSSIBLE (20-50%) THIS
MORNING, POTENTIALLY REDUCING VISIBILITIES FOR THE MORNING
COMMUTE.
- HOT/HUMID WEATHER IS EXPECTED THROUGH THE WEEKEND, WITH HIGH
TEMPERATURES RISING INTO THE 90S AND EVEN TRIPLE DIGITS. HEAT
INDEX VALUES SOARING ABOVE 100 DEGREES IS POSSIBLE (30-60%),
PARTICULARLY IN NORTH CENTRAL KANSAS.
- SHOWERS/THUNDERSTORMS ARE POSSIBLE SATURDAY MORNING AND AGAIN
SATURDAY EVENING/NIGHT. THERE IS A LOW CHANCE THAT SOME OF
THESE EVENING STORMS MAY BE STRONG TO MARGINALLY SEVERE.
- SHOWER/THUNDERSTORM CHANCES RETURN TO PORTIONS OF THE AREA
EACH DAY NEXT WEEK, ALONG WITH A COOLING TREND IN
TEMPERATURES.
UPDATE
ISSUED AT 209 AM CDT FRI AUG 7 2026
LOCALLY DENSE FOG HAS DEVELOPED ACROSS THE LOCAL AREA THIS
MORNING. AS A RESULT, A DENSE FOG ADVISORY WAS ISSUED FOR MUCH
OF THE LOCAL AREA THROUGH 10 AM CDT. NO ADDITIONAL CHANGES MADE
TO PREVIOUS FORECAST DETAILED BELOW.
WEAKENING WINDS AND SURFACE DEW POINTS IN THE UPPER 60S POSE ANOTHER
FAVORABLE ENVIRONMENT FOR FOG DEVELOPMENT THIS MORNING. THIS FOG IS
NOT EXPECTED TO BE AS DENSE OR AS WIDESPREAD AS YESTERDAY MORNING,
AS RECENT MODEL GUIDANCE HAS SUGGESTED MORE OF A LOW LEVEL STRATUS
LAYER DEVELOPING THANKS TO SOME LOW-LEVEL ISENTROPIC LIFT. IN FACT,
RECENT REFS GUIDANCE DEPICTS ONLY A 20-50% CHANCE OF SEEING
VISIBILITIES DROP BELOW 1 MILE FOR MOST OF THE AREA.
AS THE FOG/STRATUS DECK BURNS OFF MID MORNING, SKIES MAY APPEAR HAZY
THANKS TO SOME UPPER-LEVEL SMOKE BEING TRANSPORTED FROM THE PACIFIC
NORTHWEST. WARM AND HUMID CONDITIONS ARE EXPECTED TODAY, AS
TEMPERATURES INCREASE INTO THE UPPER 80S TO MID 90S TODAY ALONG WITH
DEW POINTS REACHING THE UPPER 60S TO MID 70S.
THIS HEAT/HUMIDITY WILL STICK AROUND THROUGH THE WEEKEND, AS AN
UPPER-LEVEL RIDGE BROADENS OVER THE AREA. WHILE CONDITIONS WILL
NOT BE AS EXTREME AS THEY WERE A WEEK OR SO AGO, EFI/SOT
GUIDANCE (WHICH SHOWS HOW EXTREME/RARE FORECAST CONDITIONS ARE
COMPARED TO LOCAL CLIMATOLOGY) IS SUGGESTING SLIGHTLY ABOVE
NORMAL TEMPERATURES FOR AUGUST PARTICULARLY IN NORTH CENTRAL
KANSAS, WHICH IS A SHIFT FROM THE SEASONABLY COOLER CONDITIONS
EXPERIENCED THE LAST FEW DAYS. HIGHS ARE EXPECTED TO INCREASE
INTO THE MID 90S TO TRIPLE DIGITS BY SUNDAY AND MONDAY. LREF
GUIDANCE IS SHOWING A 30-60% CHANCE OF SEEING HEAT INDEX VALUES
INCREASING TO ABOVE 100 DEGREES IN NORTH CENTRAL KANSAS EACH
AFTERNOON SATURDAY THROUGH MONDAY, THOUGH SEEING HEAT INDEX
VALUES REACHING 105 DEGREES IS NOT OUT OF THE REALM OF
POSSIBILITIES.
THE MAIN FAILURE POINT OF THESE MORE EXTREME TEMPERATURES IS THE
CHANCE OF SHOWERS/THUNDERSTORMS AS SOME "SNEAKY" WAVES MAY TRY TO
EMERGE IN THE NW FLOW ALOFT. THE FIRST OF THESE THUNDERSTORM CHANCES
COMES SATURDAY MORNING, AS SOME CAMS ARE SUGGESTING A THUNDERSTORM
CLUSTER DIVING TO THE SE FROM WESTERN SOUTH DAKOTA/NEBRASKA. HOWEVER
THERE IS QUITE A BIT OF UNCERTAINTY IN THE TIMING, COVERAGE,
AND LOCATION OF THESE STORMS. OTHER MODELS ARE SHOWING
REDEVELOPMENT OF THUNDERSTORMS SATURDAY EVENING/OVERNIGHT. THERE
IS A LOW CHANCE THAT SOME OF THESE EVENING STORMS MAY BE STRONG
TO MARGINALLY SEVERE, AS THERE IS AMPLE INSTABILITY AND SHEAR
TO WORK WITH. THE MAIN UNCERTAINTY WITH THESE STORMS IS WHEN AND
WHERE THESE THUNDERSTORMS DEVELOP.
REGARDLESS, THE HEAT WON'T LAST TOO LONG, AS MODEL CONSENSUS
SUPPORTS A COOLING TREND EARLY NEXT WEEK AS THE UPPER LEVEL RIDGE
WEAKENS AND A MORE ZONAL PATTERN EMERGES. WITHIN THIS ZONAL FLOW,
VARIOUS SHORTWAVES ARE POSSIBLE, CAUSING ENOUGH FORCING FOR
NUMEROUS PRECIPITATION CHANCES NEXT WEEK.
DISCUSSION
ISSUED AT 345 PM CDT THU AUG 6 2026
LOW CLOUDS HAVE BEEN STUBBORN TO BURN OFF TODAY THANKS TO WEAK
MIXING WITHING THE LOW LEVEL HIGH PRESSURE AXIS. THIS HIGH
PRESSURE IS SHIFTING FURTHER E AND ALLOWING FOR GRADUALLY
INCREASING S/SE LOW LEVEL FLOW AND DECREASING CLOUDS. HUMIDITY
IS BEGINNING TO INCREASE ONCE AGAIN (DEW POINTS BACK INTO HE MID
TO UPPER 60S), BUT SHOULD STILL BE A SEASONABLY PLEASANT EVENING
GIVEN THE LIGHT BREEZE AND TEMPERATURES IN THE UPPER 70S TO
LOWER 80S THROUGH SUNSET.
EXPECT ANOTHER ROUND OF STRATUS AND POTENTIALLY MORE FOG LATE
TONIGHT AND INTO FRIDAY AM WITH RETURN OF DOWNRIGHT MUGGY
CONDITIONS AND DEW POINTS IN THE LOW TO MID 70S. BUFKIT
SOUNDINGS AND MODEL PROGS SEEM TO FAVOR THIS MOISTURE ADVECTION
BEING MORE STRATUS THAN FOG, WHICH MAKES SENSE GIVEN THE STEADY
5-10 MPH SRLY WINDS TONIGHT. MODELS WERE A LITTLE OVERDONE ON
THE FOG LAST NIGHT AND ARE EVEN LESS EXCITED ABOUT IT TONIGHT,
SO HAVE MENTIONED PATCHY FOG IN THE GRIDS, BUT LEFT OUT ANY
MENTION OF DENSE FOG IN THE LATEST HWO.
MAIN STORY FOR THE WEEKEND WILL BE RETURN OF WARM/HOT AND HUMID
CONDITIONS - BUT THERE'S ALSO ONE OR TWO, ALBEIT HIGHLY
UNCERTAIN, CHANCES FOR THUNDERSTORMS TO DEAL WITH, AS WELL. DOME
OF UPPER LEVEL HIGH PRESSURE WILL BUILD/EXPAND OVER THE CENTRAL
AND SOUTHERN PLAINS AND ALLOW FOR TEMPERATURES TO SOAR INTO THE
90S, TO EVEN LOW 100S IN NORTH CENTRAL KANSAS, EACH AFTERNOON
SATURDAY AND SUNDAY. THE WARMER KS ZONES WILL ALSO SEE OVERNIGHT
LOWS CREEP BACK UP INTO MID 70S. STILL CAN'T RULE OUT THE NEED
FOR A HEAT ADVISORY FOR SOME OF THESE AREAS, ESPECIALLY TOWARDS
SUN-MON TIME FRAME, AFTER MOISTURE HAS HAD MORE TIME TO POOL
ALONG A WEAK FRONTAL ZONE. THESE AREAS WILL LIKELY SEE PEAK HEAT
INDICES NEAR THE 105F CRITERIA, AND THE WARMER OVERNIGHT LOWS
WILL ADD TO THE "ACCUMULATIVE EFFECTS" THAT COME WITH HIGH HEAT.
ON THE OTHER HAND, IT'S NOW EARLY AUGUST AND WE'RE WELL
ACCUSTOMED TO THE HEAT THAT WAS EVEN HIGHER A COUPLE WEEKS AGO.
WILL CONTINUE TO MONITOR TRENDS FOR ANY SIGNS OF AN UPWARD TICK
IN DEW POINTS OR AIR TEMPERATURES AND POTENTIAL NEED FOR A HEAT
HEADLINE - AGAIN, MAINLY ALONG AND S OF THE NE/KS STATE LINE.
SEVERAL WEAK WAVES ROUNDING THE EDGE OF THE UPPER LEVEL HIGH
COULD LEAD TO SOME SPORADIC SHOWER AND THUNDERSTORM CHANCES,
MAINLY IN THE SATURDAY TO SATURDAY NIGHT TIME FRAME. CAMS ARE
QUITE INCONSISTENT WITH DETAILS, HOWEVER - DIFFERING
SIGNIFICANTLY ON WHERE AND WHEN THE BEST CHANCES WILL BE. SOME
GUIDANCE POINTS TOWARDS MAINLY A SATURDAY AM CHANCE, WHEREAS
OTHER MODELS WEAKEN THE AM ACTIVITY BEFORE IT GETS TO US AND
PUTS THE HIGHEST CHANCES WITH POTENTIAL REDEVELOPMENT IN THE
EVENING AND OVERNIGHT HOURS. INSTABILITY PROBABLY WON'T BE A
LIMITING FACTOR REGARDLESS OF SCENARIO, AND REGION WILL BE ON
THE SOUTHERN FRINGES OF GREATER DEEP LAYER SHEAR...SO AT LEAST
SOME MENTION OF SEVERE WEATHER POTENTIAL SEEMS WARRANTED. JUST
REALLY DIFFICULT TO PIN POINT MORE SPECIFIC DETAILS AT THIS
TIME, UNFORTUNATELY.
MODELS STILL SUPPORT THE IDEA OF GRADUALLY COOLING TEMPERATURES
AND MORE ACTIVE WEATHER PATTERN FOR ROUGHLY THE SECOND HALF OF
NEXT WEEK. TEMPERATURES SHOULD DIP BACK DOWN INTO PRIMARILY 80S
FOR NEB ZONES BY WEDNESDAY, THEN AREA WIDE FOR THURSDAY. THE
UPPER RIDGE WILL BREAK DOWN SOME AND REORIENT FROM THE DESERT SW
INTO MORE OF THE DEEP SOUTH, WHICH SHOULD ALLOW FOR A STEADY
STREAM OF MONSOONAL MID TO UPPER LEVEL MOISTURE TO STREAM INTO
THE REGION AND INTERACT WITH FREQUENT SHORTWAVES EMBEDDED WITHIN
ZONAL TO NW UPPER FLOW. FAR TOO EARLY FOR MUCH IN THE WAY OF
DETAILS, BUT BROADLY SPEAKING, THE PATTERN SHOULD FAVOR AN
INCREASE IN SHOWER AND THUNDERSTORM POTENTIAL, LIKELY ON A DAILY
BASIS...AND THIS IS CONFIRMED IN RECENT ENSEMBLE PRECIP ANOMALY
PLOTS FOR NEXT WEEK. HOPEFULLY THIS PANS OUT, AS MANY AREAS
COULD USE SOME MOISTURE NOW, BUT ESPECIALLY NEXT WEEK AFTER THE
HOT, AND MAINLY DRY, WEEKEND.
AVIATION /06Z TAFS THROUGH 06Z SATURDAY/
ISSUED AT 1245 AM CDT FRI AUG 7 2026
FOR KGRI/KEAR AIRPORTS:
LOW LEVEL STRATUS CAN BE SEEN DEVELOPING ACROSS CENTRAL
NEBRASKA EARLY THIS MORNING ON LATEST SATELLITE IMAGERY. EXPECT
THIS STRATUS TO EXPAND IN COVERAGE OVER THE NEXT FEW HOURS,
WITH IFR CIGS EVENTUALLY POSSIBLE LATE IN THE NIGHT AT BOTH
TERMINALS. COULD ALSO SEE SOME MODEST BR...WITH MVFR VSBYS...BUT
MORE DENSE FOG IS NOT EXPECTED IN THIS SET-UP. EXPECT STEADY
SOUTHEASTERLY WINDS LESS THAN 10 KTS TO CONTINUE THROUGH THE
MORNING HOURS, EVENTUALLY BECOMING SOUTHWESTERLY AROUND
07/14Z...WITH STRATUS ALSO LIFTING AND BECOMING MVFR THROUGH
07/19Z BEFORE MOSTLY SUNNY SKIES (PREVAILING VFR CONDITIONS)
RETURN.
