Hail in Nebraska, July 10 to 11, 2015

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HASTINGS NE
627 PM CDT FRI JUL 10 2015

.SHORT TERM...(THIS EVENING THROUGH SATURDAY)
ISSUED AT 317 PM CDT FRI JUL 10 2015

THE SHORT TERM REALLY ENTAILS THE WARM TEMPERATURES SATURDAY
AFTERNOON NEAR HEAT ADVISORY CONDITIONS AND THE CHANCE FOR
THUNDERSTORMS TONIGHT EARLY SATURDAY MORNING....AND THEN AGAIN
SATURDAY AFTERNOON/EVENING.

ALOFT WE REMAIN IN MOSTLY SOUTHWESTERLY SLOW DURING THIS TIME PERIOD
UNTIL LATER SATURDAY WHEN THE RIDGE OVER THE EAST BEGINS TO BUILD IN
WESTWARD OVER SOUTHERN PARTS OF THE CONUS AND THE FLOW ALOFT BECOMES
MORE ZONAL. AT THE SURFACE...WE WILL EXPERIENCE MOSTLY SOUTHERLY
FLOW WHICH WILL HELP KEEP DEWPOINTS IN THE MID/UPPER 60S TO LOWER
70S THROUGH SATURDAY. THESE DEWPOINTS COUPLED WITH HIGH TEMPERATURES
RANGING FROM THE LOWER 90S TO ABOUT 101 DEGREES WILL CREATE HEAT
INDICES RANGING FROM THE MID 90S TO ABOUT 105 SATURDAY AFTERNOON.
OUR NORTH CENTRAL KANSAS COUNTIES LOOK LIKE THEY WILL BE AROUND 101
TO 105 DEGREES FOR HEAT INDEX VALUES SATURDAY AFTERNOON. THIS IS
VERY CLOSE TO OUR HEAT ADVISORY CRITERIA...BUT BECAUSE IT IS VERY
BORDERLINE...A HEAT ADVISORY WILL NOT BE ISSUED AT THIS TIME DUE TO
UNCERTAINTIES.

A WARM FRONT WILL CONTINUE TO SLOWLY PUSH NORTHWARD THIS AFTERNOON
AND TONIGHT BEFORE STALLING OUT ACROSS SOUTHERN PARTS OF NEBRASKA.
THE FRONT THEN PUSHES NORTHWARD OUT OF THE OUTLOOK AREA SATURDAY.
THE BETTER CHANCES FOR THUNDERSTORMS WILL BE THIS EVENING AND
TONIGHT. HOWEVER...ITS NOT TOTALLY OUT OF THE QUESTION WE GET A FEW
STORMS TO INITIATE LATE THIS AFTERNOON. WIDESPREAD SEVERE WEATHER IS
NOT EXPECTED AT THIS TIME...BUT A FEW STORMS COULD BE ON THE STRONG
SIDE WITH HAIL NEAR THE SIZE OF A NICKEL AND WIND SPEEDS AROUND 50
MPH WITHIN THE STRONGER STORMS. TAKING A LOOK AT SOME OF THE MORE
REFINED DETAILS FOR THUNDERSTORM CHANCES TODAY INTO TONIGHT...WE
LOOK FIRST AT INSTABILITY WHERE MUCAPE VALUES RANGE FROM A FEW
HUNDRED TO ABOUT 1500 J/KG THIS AFTERNOON AND THEN ABOUT 1000 TO
2000 J/KG THIS EVENING. BULK SHEAR 0-6 KM RANGES BETWEEN 35 TO 40
KNOTS AND LOW LEVEL HELICITY VALUES RANGE UP TO NEAR 100 (M^2/S^2)
IN THE 0-1 KM LAYER. LAPSE RATES BETWEEN 925 AND 700 MB RANGE
BETWEEN 6 TO 8 (C/KM). ALTHOUGH THE PARAMETERS ARE THERE FOR
THUNDERSTORMS DEVELOPMENT...WE ARE MISSING A TRIGGERING MECHANISM TO
GET THESE STORMS INITIATED THIS AFTERNOON. THINGS COULD GET
INTERESTING IF WE CAN GET SOME AIR PARCELS TO RISE. ONCE THE WARM
FRONT MOVES FARTHER NORTH AND THE LLJ KICK IN WE SHOULD NOT HAVE A
PROBLEM GETTING THUNDERSTORMS TO DEVELOP TONIGHT WITH A FEW STRONG
STORMS NOTED.

WE SHOULD GET A BREAK IN THUNDERSTORMS BETWEEN THE EARLY SATURDAY
MORNING HOURS AND SATURDAY LATE AFTERNOON. SATURDAY IS ANOTHER DAY
WHERE WE LACK TRUE FORCING. WE WILL HAVE AMPLE MUCAPE RANGING
BETWEEN ABOUT 1500 AND 2500 J/KG...OR THE NAM WHICH WHICH SHOWS
VALUES CLOSER TO 4000 J/KG LATER IN THE AFTERNOON...AND SHEAR VALUES
ARE SIMILAR TO TODAYS VALUES WITH 0-6 KM BULK SHEAR AROUND 30 TO 40
KNOTS AND 0-1 KM HELICITY VALUES APPROACHING 100 (M^2/S^2) FOR THE
HIGH END. OVERALL...IT DOES NOT APPEAR THAT WIDESPREAD SEVERE
WEATHER WILL OCCUR BUT A FEW STRONG STORMS MAY FORM TOMORROW
AFTERNOON INTO THE EVENING HOURS.

.LONG TERM...(SATURDAY NIGHT THROUGH FRIDAY)
ISSUED AT 317 PM CDT FRI JUL 10 2015

GUIDANCE SUGGESTS SOUTHWESTERLY UPPER TROPOSPHERIC FLOW WILL BE
NOTED OVER THE CENTRAL PLAINS TO START THE LONG-TERM FORECAST PERIOD
AT 00Z SUNDAY. THIS SOUTHWESTERLY SHOULD BECOME MORE ZONAL DURING
THE DAY SUNDAY AS AN UPPER TROPOSPHERIC RIDGE MOVES FROM THE
SOUTHEASTERN CONUS INTO THE SOUTH CENTRAL AND SOUTHWESTERN CONUS
DURING THE WEEKEND. QUASI-ZONAL TO NORTHWESTERLY UPPER TROPOSPHERIC
FLOW IS THEN EXPECTED OVER THE REGION THROUGH MUCH OF NEXT WEEK.

LITTLE IF ANY OMEGA IS EXPECTED ACROSS THE REGION SUNDAY THROUGH THE
DAY TUESDAY WHICH SHOULD PROVIDE DRY CONDITIONS FOR THE MOST PART.
THE ONLY EXCEPTION MIGHT BE SATURDAY EVENING...AND AGAIN MONDAY
AFTERNOON THROUGH TUESDAY. BOTH OF THESE TIME PERIODS FEATURE A VERY
LIMITED OPPORTUNITY...NO GREATER THAN 20%...FOR ISOLATED CONVECTION
AS DIABATIC HEATING POTENTIALLY BREACHES THE LOWER TROPOSPHERIC
CAPPING INVERSION. A BETTER CHANCE FOR PRECIPITATION PRODUCTION IS
EXPECTED TO OVERTAKE THE ENTIRE CWA DURING THE MIDDLE TO LATE OF
NEXT WEEK AS AS ENHANCED UPPER TROPOSPHERIC JET DYNAMICS AND
MULTIPLE UPPER TROPOSPHERIC PERTURBATIONS INFILTRATE THE AREA. GIVEN
THIS...20-40% POPS REMAIN INTACT ACROSS MUCH OF THE CWA DURING THE
MIDDLE TO LATE PART OF NEXT WEEK.

ALTHOUGH THE PROBABILITY OF PRECIPITATION ACTUALLY BEING REALIZED
SATURDAY EVENING IS VERY LOW...THERE WILL BE AT LEAST A CHANCE FOR A
STRONG STORM OR TWO SHOULD CONVECTION BE REALIZED. THIS IS HANDLED
IN GREATER DETAIL IN THE SHORT-TERM DISCUSSION ABOVE.

THERMAL ADVECTION THROUGH THE BOUNDARY LAYER WILL PROMOTE A
NOTICEABLE WARM UP ACROSS THE REGION THIS WEEKEND...WITH GUIDANCE
SUGGESTING AFTERNOON HIGHS WILL SOAR WELL INTO THE 90S AND LOW 100S
SUNDAY AND MONDAY. THE INFILTRATION OF A SLIGHTLY COOLER BOUNDARY-
LAYER AIR MASS WILL THEN PROMOTE COOLER HIGHS TUESDAY ONWARD...WITH
HIGHS GENERALLY IN THE 80S AND 90S. AFTERNOON AND EARLY EVENING HEAT
INDEX READINGS GENERALLY IN THE 100-105 DEGREE RANGE ARE STILL
EXPECTED OVERTAKE MUCH OF THE CWA ON SUNDAY...AND MAINLY SOUTHERN
PORTIONS OF THE AREA ON MONDAY. WILL CONTINUE HEAT INDEX WORDING IN
THE HWO AS A RESULT.

.AVIATION...(FOR THE 00Z KGRI/KEAR TAFS THROUGH 00Z SATURDAY EVENING)
ISSUED AT 618 PM CDT FRI JUL 10 2015

PRIMARY FORECAST CONCERN THROUGH THE TAF LIES WITH THIS
EVENING/OVERNIGHT AND PRECIP CHANCES. SHORT TERM/HI RES MODELS
HAVENT HAD THE BEST HANDLE WITH ONGOING ACTIVITY...SO CONFIDENCE
IN WHAT THEY ARE SHOWING OVER THE NEXT 6-12 HOURS ISNT HIGH. KEPT
ANY PRECIP MENTION AT VC UNTIL THINGS BECOME MORE CLEAR FOR THE
TERMINAL AREAS. KEPT THE DAYTIME HOURS DRY AT THIS TIME...THOUGH
THERE IS A SLIGHT CHANCE OF PRECIP LATE IN THE DAY. NOT A LOT OF
CHANGE IN EXPECTED IN WINDS THROUGH THE PERIOD...WHICH WILL REMAIN
S/SERLY.
