NATIONAL WEATHER SERVICE HASTINGS NE
439 AM CDT TUE JUN 24 2025
KEY MESSAGES
- PERIODIC ROUNDS OF SCATTERED THUNDERSTORMS WILL REMAIN
POSSIBLE TODAY THROUGH THURSDAY, GENERALLY FAVORING THE LATE
AFTERNOON INTO OVERNIGHT PERIODS.
- WIDESPREAD SEVERE WEATHER AND HEAVY RAIN IS NOT EXPECTED.
HOWEVER, ISOLATED INSTANCES OF MARGINALLY SEVERE HAIL/WIND,
ALONG WITH QUICK BURSTS OF 1-2" OF RAIN, WILL BE POSSIBLE.
- TEMPERATURES TREND WARMER, CLOSER TO SEASONABLE LEVELS, TODAY
THROUGH THURSDAY BEFORE A RETURN TO HOT AND MAINLY DRY
CONDITIONS FOR FRIDAY AND INTO THE WEEKEND.
- THE NEXT COLD FRONT LOOKS TO ARRIVE SUN/SUN NIGHT AND BRING
OUR NEXT CHANCE FOR MOISTURE AND DROP TEMPERATURES BACK TO
SEASONABLE LEVELS FOR EARLY NEXT WEEK.
DISCUSSION
ISSUED AT 435 AM CDT TUE JUN 24 2025
QUIET CONDITIONS ARE IN PLACE EARLY THIS MORNING AS THE AREA
REMAINS TO THE COOL SIDE OF YESTERDAY'S COLD FRONT. COOL
CONDITIONS WILL CONTINUE THROUGH THE MORNING HOURS AS THE AREA
REMAINS ENTRENCHED UNDER WIDESPREAD STRATUS. MAY ALSO BE SOME
PATCHY AREAS OF LIGHT TO MODERATE FOG OVER PORTIONS OF SOUTH
CENTRAL NEBRASKA FOR A FEW HOURS AROUND DAWN THANKS TO T/TD
SPREADS OF 1-3 DEGREES AND WEAK ERLY UPSLOPE FLOW. WHILE
MECHANICAL MIXING WILL REMAIN WEAK THROUGH MIDDAY, ESSENTIALLY
MAX ANNUAL SUN ANGLE SHOULD HELP TO LIFT AND DISSIPATE THE
STRATUS GRADUALLY THIS AFTERNOON. THIS WILL COINCIDE WITH THE
AFOREMENTIONED BOUNDARY FROM YESTERDAY BECOMING MORE DIFFUSE AND
LIFTING NORTHWARD AS A WEAK WARM FRONT. THUS, NO CHANGES MADE TO
FORECAST HIGHS FOR TODAY (UPPER 70S FAR N, TO UPPER 80S ALONG/S
OF THE STATE LINE) AS SHOULD SEE A QUICK WARMUP AS CLOUDS THIN
OUT THIS AFTERNOON.
SCATTERED THUNDERSTORMS SHOULD REDEVELOP AT SOME POINT LATE THIS
AFTERNOON INTO EVENING, THOUGH LATEST HI-RES GUIDANCE AND HRRR
TRENDS REMAIN MIXED ON DETAILS - SUCH AS EXACTLY WHERE, WHEN,
AND COVERAGE. TYPICALLY A NORTHWARD RETREATING WARM FRONT IN
LATE JUNE WOULD RAISE EXPECTATIONS FOR ORGANIZED SEVERE
WEATHER...HOWEVER THAT DOESN'T APPEAR TO BE THE CASE THIS GO-
AROUND DUE TO WEAK WIND SHEAR AND RELATIVELY POOR LAPSE RATES.
SEASONABLY MODEST INSTABILITY (CAPE OF 1000-2000 J/KG) AND
EFFECTIVE DEEP LAYER SHEAR OF 20-25KT COULD SUPPORT AN ISOLATED,
MARGINALLY SEVERE STORM, OR TWO...BUT ORGANIZED SEVERE RISK IS
UNLIKELY. LATEST SPC DAY 1 OUTLOOK FEATURES A MARGINAL RISK
(LEVEL 1 OF 5) FOR THE ENTIRE FORECAST AREA TO COVER THIS
POTENTIAL. MORE PROBABLE ISSUE, IF THERE'S GOING TO BE ONE,
COULD BE PERIODIC/SCATTERED INSTANCES OF HIGH RAIN RATES AND
LOCALLY HEAVY RAINFALL AMOUNTS. 00Z EPS PUTS PWATS AT 1.8-2.0"
AFTER 21Z INTO THE OVERNIGHT...WHICH IS OVER 150 PERCENT OF
NORMAL OR 2.5-3.0 STANDARD DEVIATIONS ABOVE NORMAL. COULD
CERTAINLY ENVISION LOCALIZED INSTANCES OF 1-2" IN ONLY 30-60
MIN. FORTUNATELY, THESE TYPES OF RATES SHOULDN'T BE WIDESPREAD
OR PERSISTENT...THUS KEEPING IMPACTS ISOLATED.
KIND OF A WASH, RINSE, REPEAT FOR WEDNESDAY AS THE AM TO EARLY
AFTN HRS APPEAR MAINLY DRY. MAY NOT BE QUITE THE AMOUNT OF LOW
CLOUDS IN THE AM, SO EARLIER START TO THE WARMUP, ALONG WITH
STRONGER SRLY FLOW, SHOULD SUPPORT WARM/HOT TEMPERATURES IN THE
MID 80S TO MID 90S FROM N TO S. SIMILAR TO TODAY, EXPECT
SCATTERED THUNDERSTORMS TO DEVELOP ONCE AGAIN DURING THE LATE
AFTERNOON AND EARLY EVENING HOURS. THIS ROUND LOOKS TO FAVOR
AREAS W THROUGH N OF THE TRI-CITIES, AT LEAST INITIALLY, AS
ACTIVITY DEVELOPS ALONG A SW TO NE BOUNDARY/BAROCLINIC ZONE.
ONCE AGAIN, INSTABILITY IS A BIT MODEST FOR LATE JUNE...BUT
THERE ARE SOME INDICATIONS FOR MAYBE SOME SLIGHTLY STRONGER
DEEP LAYER SHEAR THANKS TO SUBSTANTIAL LOW LEVEL VEERING AND
TAIL END OF 25-35KT FLOW BETWEEN 700MB AND 500MB. MARGINALLY
SEVERE HAIL, 60MPH DOWNBURST WIND GUSTS, AND LOCALLY HEAVY RAIN
WILL AGAIN BE THE PRIMARY THREATS WITH STRONGEST CORE.
THUNDERSTORMS WILL BE POSSIBLE JUST ABOUT ANYWHERE, THOUGH SREF
CALIBRATED SEVERE PROBS ARE INDEED SLIGHTLY HIGHER THAN TODAY,
AND FOCUSED HIGHEST OVER AREAS ALONG/N OF HWY 92.
MODELS SAG A WEAK TROUGH/COLD FRONT INTO THE AREA ON THURSDAY,
SO HIGHS SHOULD FALL BACK INTO THE 80S AS SCATTERED SHOWER/STORM
CHANCES CONTINUE FOR ONE MORE DAY. STILL EXPECT A PERIOD OF
MAINLY DRY CONDITIONS AND HOTTER TEMPERATURES TO RETURN FRIDAY
AND PERSIST INTO THE WEEKEND. LATEST BLEND PUTS HOTTEST TEMPS ON
SATURDAY WITH WIDESPREAD HIGHS IN THE 90S - PERHAPS EVEN LOW
100S IN FAVORED WARM SPOTS IN THE SW PART OF FORECAST AREA.
THERE ARE STILL SOME SPORADIC LOW-END POPS EACH DAY, BUT THIS
APPEARS TO BE TIED TO CONVECTION THAT MAY OR MAY NOT MOVE OFF
THE HIGH PLAINS DURING THE OVERNIGHT HOURS. A MORE COHERENT
TROUGH/SURFACE FRONT LOOKS TO ARRIVE SOME TIME LATER ON SUN INTO
SUN NIGHT. THIS SHOULD DROP TEMPS BACK TO SEASONABLE LEVELS AND
BRING US NEXT DECENT CHANCE (40-50 PERCENT) FOR RAIN. HOPEFULLY
WE CAN SPREAD OUT THE MULTIPLE RAIN CHANCES OVER THE NEXT WEEK
AND GIVE EVERYONE SOME NEEDED MOISTURE AFTER LAST WEEKEND'S
MULTIPLE-DAY BOUT OF VERY HOT AND VERY WINDY CONDITIONS.
AVIATION /06Z TAFS THROUGH 06Z WEDNESDAY/
ISSUED AT 1258 AM CDT TUE JUN 24 2025
FOR KGRI/KEAR AIRPORTS:
SIGNIFICANT WEATHER: IFR TO LIFR CIGS THIS MORNING.
ONGOING MVFR CIGS ARE FORECAST TO DIP LOWER TO IFR OVER THE
NEXT FEW HOURS, AND PERHAPS EVEN MAKE A RUN INTO LIFR TERRITORY
AROUND SUNRISE FOR A FEW HOURS. WITH THE LIFR CIGS COULD ALSO
COME MVFR VSBYS. CAN'T RULE OUT AN HOUR OR TWO OF IFR VSBYS.
HIGH SUN ANGLE SHOULD ALLOW FOR SOME GRADUAL IMPROVEMENT MID TO
LATE AM - RETURNING TO MVFR BY AROUND 16-18Z.
HAVE VFR CIGS FOR LATE AFTERNOON INTO TUE EVE, BUT THIS IS
LOWER CONFIDENCE AS SOME GUIDANCE JUST CONTINUES THE MVFR CIGS.
VARIOUS HI-RES MODELS DEVELOP ISO-SCAT CONVECTION AT SOME POINT
IN THE REGION LATE AFTERNOON INTO EARLY EVENING, BUT DISAGREE ON
SPECIFIC COVERAGE AND TIMING. THUS, WILL BROAD BRUSH THE
21Z-06Z TIME FRAME WITH PROB30S, FOR NOW. WINDS WILL BE
RELATIVELY LIGHT THROUGH THE PERIOD, VEERING FROM NNE NOW, TO E
BY AROUND MIDDAY, TO SERLY THIS EVENING AND OVERNIGHT.
CONFIDENCE: CIGS/WIND - MEDIUM TO HIGH, VSBYS - MEDIUM, TSRA
DETAILS: LOW.
