Area forecast discussion, Jul 15, 6:24 PM CDT, 19 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HASTINGS NE
624 PM CDT FRI JUL 15 2011
.AVIATION...00Z TAF. THUNDERSTORMS HAVE DEVELOPED TO THE SOUTHWEST
OF KGRI TERMINAL AREA. THEY SHOULD BE REACHING THE AREA IN A
WHILE. THEY ARE SCATTERED AND COULD BE IN AND OUT FOR A SHORT
TIME. ONCE THE THUNDERSTORMS MOVE OUT OF THE AREA THE ONLY CONCERN
WILL BE SOME WIND SHEAR LATE TONIGHT.
&&
.PREV DISCUSSION... /ISSUED 402 PM CDT FRI JUL 15 2011/
SHORT TERM...TONIGHT THROUGH 12Z SUNDAY. PRIMARY FORECAST CONCERNS LIE WITH
PRECIPITATION CHANCES AND INCREASING WARMTH/DEWPOINTS.
LITTLE CHANGE IN THE INCREASINGLY AMPLIFIED UPPER LEVEL PATTERN
ACROSS THE CONUS TODAY...WITH UPPER LEVEL AND SATELLITE DATA
CONTINUING TO SHOW RIDGING THROUGH THE PLAINS AS DEEP TROUGHS SIT
JUST OFF THE EAST COAST AND ALONG THE WEST COAST. AT THE
SURFACE...THE PATTERN TOOK A LITTLE BIT TO BECOME BETTER ORGANIZED
IN THE WAKE OF THIS MORNINGS SHOWERS/ISLD THUNDERSTORMS...BUT
CURRENTLY ARE SEEING AN ELONGATED AREA OF LOW PRESSURE OVER WRN
KANSAS...WHILE A NOTABLE WARM FRONT/DRYLINE BOUNDARY LIES DRAPED
OVER THE FAR SRN FRINGE OF THE CWA. WITH THE STRONGER HEATING SOUTH
OF THAT BOUNDARY /TEMPS OF 105-110/ IS RESULTING IS SOME VERY STEEP
LAPSE RATES...AND ARE SEEING SOME SCT SHOWERS/THUNDERSTORMS
DEVELOPING...BUT WITH MID LEVEL TEMPS BEING ON THE WARM SIDE...THAT
CAPPING AT THIS POINT IS HELPING TO KEEP THINGS FROM GETTING TOO
TALL. ACROSS THE N/NERN PORTIONS OF THE CWA...HAVE SEEN A FAIRLY
SMALL BUT PERSISTENT AREA OF ACTIVITY THROUGH THE DAY...DRIVEN BY A
WEAK MID LEVEL DISTURBANCE PUSHING EAST ALONG WITH WARM AIR/THETAE
ADVECTION...AND FOCUSED PRIMARILY ALONG A LOW/MID LEVEL CONVERGENCE
ZONE. THIS ACTIVITY IS /AND SHOULD CONTINUE/ SHIFTING EAST.
DECIDED TO UP POPS TO CHANCE AND EXPAND IN COVERAGE INTO THIS
EVENING...AND THEN KEPT POPS OUT OF THE FORECAST POST-06Z WITH MUCH
OF THIS ACTIVITY BEING AFFECTED BY THE SUN SETTING. AGAIN THERE IS
PLENTY OF INSTABILITY...BUT SHEAR ISNT THE GREATEST...AND ANY
ACTIVITY SHIFT NORTH INTO OUR CWA IT WILL ALSO RUN INTO LOWER LAPSE
RATES. WILL KEEP THE MENTION OF A FEW STRONG/SEVERE THUNDERSTORMS IN
THE HWO...WITH SUCH HIGH FREEZING LEVEL HEIGHTS NEEDED FOR HAIL WILL
LEAVE SIZE AT QUARTERS...BUT OVERALL COVERAGE SHOULD NOT BE TOO
EXTENSIVE.
AS FAR AS PRECIPITATION CHANCES GO INTO SATURDAY/SATURDAY
NIGHT...MODELS CONTINUE TO VARY ON WHETHER THE MID LEVEL
TEMPERATURES WILL BE ENOUGH TO KEEP THINGS CAPPED OFF...OR IF IT
WILL BE SOMETHING SIMILAR TO TODAY WHERE WE CAN GET STEEP ENOUGH
LAPSE RATES AND ENOUGH WEAKENING IN THE CAP THAT THINGS CAN
DEVELOP. DECIDED TO STAY ON THE DRY SIDE WITH THE CONTINUED
STRENGTHENING OF THE RIDGE AND WARMER TEMPERATURES BUILDING
IN...COMPARED TO TODAY...BUT WILL STATE THAT CONFIDENCE IS NOT HIGH
THAT THE ENTIRE CWA WILL BE PRECIPITATION FREE ALL OF SAT/SAT NIGHT.
BIG CONCERN IN THE SHORT TERM LIES WITH THE RISING TEMPERATURES AND
DEW POINTS ACROSS THE ENTIRE CWA AS A RESULT OF THE AMPLIFYING RIDGE
THROUGH THE PLAINS AND PERSISTENT SOUTHERLY FLOW DRAWING WARMER/MORE
MOIST AIR INTO THE REGION. AS FAR AS HEAT INDEX VALUES GO
SATURDAY...THERE IS ONCE AGAIN CONCERN ABOUT THE POTENTIAL FOR SOME
CLOUDS /AND PERHAPS PRECIPITATION/ AFFECTING TEMPERATURES FOR SOME
AREAS. BUT LIKE TODAY...IF THERE IS CLOUD COVER...ANY /EVEN SHORT/
BREAKS IN THE CLOUD COVER WILL ALLOW TEMPS TO QUICKLY JUMP UP. AND
SEE NO REASON WHY DEWPOINTS TOMORROW SHOULD BE NOTABLY DIFFERENT
THAN TODAY...IN THE MID/UPPER 70S ACROSS MOST OF THE CWA...WITH
LOWER DPTS IN THE SOUTH WHERE BETTER MIXING POTENTIAL LIES. HEAT
INDEX VALUES ARE EXPECTED TO REMAIN ABOVE 100-105+...WITH THE
NORTHERN 2/3 OF THE CWA A RESULT OF LOWER ACTUAL TEMPERATURES BUT
HIGHER DPTS...WHERE THE SOUTH WILL HAVE LOWER DPTS BUT HIGHER ACTUAL
TEMPERATURES. DECIDED TO KEEP THINGS SIMPLE...ITS GOING TO BE
HOT...AND EXPANDED THE EXC HEAT WARNING FOR THE ENTIRE CWA.
LONG TERM...SUNDAY THROUGH FRIDAY. FOCUS IS ON THE CONTINUATION OF
HOT TEMPERATURES INTO NEXT WEEK...WITH SOME REPRIEVE TOWARD DAY 7.
THE UPPER RIDGE AXIS WILL BE ENTRENCHED ACROSS THE CENTRAL PLAINS
SUNDAY THROUGH AT LEAST ON WEDNESDAY. THIS WILL RESULT IN
ESSENTIALLY DRY CONDITIONS AND VERY HOT TEMPERATURES. AFTERNOON
HIGHS WILL RISE WELL INTO THE 90S...AND TOP 100 DEGREES AT TIMES
WHILE LOWS AVERAGE IN THE 70S TO NEAR 80 DEGREES. WITH HIGH
DEWPOINTS IN PLACE...THE COMBINATION OF THE HOT TEMPERATURES AND
HIGH HUMIDITY WILL LEAD TO A PROLONGED PERIOD OF HEAT INDICES FROM
105 TO 115 DEGREES. DUE TO THE EXTENSIVE HEAT FOR SEVERAL
DAYS...WILL JUST GO WITH AN EXCESSIVE HEAT WARNING THROUGH
WEDNESDAY.
ALTHOUGH STILL HOT ON THURSDAY AND FRIDAY...THE UPPER RIDGE AXIS
BEGINS TO SHIFT TO THE SOUTHEAST SOME AND HEAT INDICES SHOULD BEGIN
TO DROP SOME. WILL NEED TO KEEP AN EYE ON WHETHER ADDITIONAL DAYS
MAY NEED TO BE ADDED TO THE HEADLINE...BUT WILL GO WITH THE DAYS
WHERE CONFIDENCE IS HIGHER FOR NOW. AS THE RIDGE BEGINS TO SHIFT
SOUTHEAST IN THE LATTER PERIODS...CONVECTIVE CHCS BEGIN TO INCREASE
ON THE PERIPHERY OF THE RIDGE AND HAVE ADDED SOME LOW POPS INTO THE
THURSDAY NIGHT PERIOD.
