AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
630 PM CDT WED AUG 6 2014

.SHORT TERM...(THIS EVENING THROUGH THURSDAY)
ISSUED AT 330 PM CDT WED AUG 6 2014

PRECIPITATION CHANCES TO HEADLINE THE SHORT TERM DISCUSSION
...WITH A LESSER EMPHASIS PLACED ON FOG POTENTIAL THURSDAY
MORNING.

THIS EVENING AND TONIGHT...SHOWERS AND STORMS ARE CURRENTLY
POPPING UP ACROSS THE WESTERN SANDHILLS AS A WEAK WAVE PROGRESSES TO
THE EAST.  THIS ACTIVITY SHOULD REMAIN ISOLATED AS DRY AIR IS
ADVECTING IN FROM THE SOUTHWEST.  CURRENT MESOANALYSIS SUPPORTS AT
LEAST A MENTION OF A STRONG STORM OR TWO...DESPITE RATHER WEAK LOW
AND MID LEVEL LAPSE RATES AND ONLY MODEST SHEAR...INSTABILITY HAS
INCREASED SOME ACROSS SOUTHWEST NEBRASKA AND THE EASTERN
PANHANDLE...A WET MICROBURST OR SUB-SEVERE HAIL WOULD BE POSSIBLE IF
A STORM WERE TO REALLY GET GOING.  PWATS HAVE DECREASED NOTICEABLY
FROM YESTERDAY...BUT STILL LINGERING IN THE 1.25-1.50" RANGE...AND
WITH SLOWER THAN AVERAGE STORM MOTIONS...HEAVY RAIN IS POSSIBLE.

THURSDAY...PROGRESSIVE QUASI-ZONAL FLOW ALOFT WILL USHER ANOTHER
WEAK MID-LEVEL IMPULSE ACROSS THE CENTRAL PLAINS...PROVIDING FOR
INCREASING CHANCES OF SHOWERS AND STORMS CAPABLE OF PRODUCING HEAVY
RAINFALL AND POSSIBLY SEVERE WEATHER.  WITHIN A WEAK LOW LEVEL
UPSLOPE REGIME...FORCING FOR ASCENT SHOULD BECOME MAXIMIZED DURING
THE AFTERNOON HOURS...WITH STORM FORMATION FAVORING A STALLED HIGH
PLAINS BOUNDARY. IF SUFFICIENT CLEARING OCCURS...MODERATE
TROPOSPHERIC DESTABILIZATION IS ANTICIPATED...WITH UPWARDS OF 1500
J/KG OF CAPE AVAILABLE.  0-6 KM BULK SHEAR IS SHOWN TO INCREASE IN
EXCESS OF 35 KTS BY LATE AFTERNOON ACROSS WESTERN NEBRASKA...FURTHER
SUPPORTING A SEVERE THREAT.  HEAVY RAINFALL IS ALSO A
CONCERN...ESPECIALLY BEYOND 00Z FRIDAY IF A CONVECTIVE COMPLEX
FORMS.   THE AVAILABLE CAPE IS SHOWN TO BE SPREAD THROUGH A LARGE
LAYER OF THE TROPOSPHERE...WITH WARM CLOUD LAYERS OF 6000FT OR
SO...BUT WHEN COMBINED WITH PWATS OF 1.25"-1.50" AND RELATIVELY SLOW
STORM MOTIONS...MINOR FLOODING MAY BE POSSIBLE BEFORE 00Z FRIDAY.

STRATUS AND/OR FOG IS ONCE AGAIN ANTICIPATED OVERNIGHT
TONIGHT...GENERALLY FAVORING THE SREF WHICH INDICATES THE BEST
OPPORTUNITY OF LOW CLOUDS ACROSS THE CENTRAL SANDHILLS AND POINTS
NORTH OR EAST.  THE PATTERN IS FAVORABLE WITH WEAK LOW LEVEL UPSLOPE
OVERNIGHT...AND WITH THE RECENT RAINFALL...FOG SHOULD BE REALIZED.
THE X-OVER TEMPERATURE IS GENERALLY IN THE MID 60S...OVERNIGHT LOWS
SHOULD ECLIPSE THAT MARK.

HIGHS ON THURSDAY WILL ONCE AGAIN BE MODERATED BY THE PRESENCE OF
CLOUDS/SHOWERS AND WEAK EASTERLY UPSLOPE FLOW.  HIGHS IN THE UPPER
70S TO LOWER 80S SHOULD PREVAIL FOR MOST OF THE SANDHILLS AND POINTS
EAST...BUT ACROSS OUR FAR WESTERN AND SOUTHWEST ZONES...RETURN FLOW
OFF THE HIGH PLAINS WILL HELP PUSH MAX T/S INTO THE MID 80S.

.LONG TERM...(THURSDAY NIGHT THROUGH WEDNESDAY)
ISSUED AT 330 PM CDT WED AUG 6 2014

HIGHER CONFIDENCE FOR THE POTENTIAL OF A THUNDERSTORM COMPLEX
DEVELOPING ACROSS SOUTHWEST NEBRASKA THURSDAY EVENING. MODELS ARE
IN GOOD AGREEMENT WHERE CONVECTION THAT DEVELOPS ON THE HIGH
PLAINS BY EVENING WILL DEVELOP EAST SOUTHEAST. AS THE H85
JETSTREAK STRENGTHENS TO 35-40 KTS SEE STORMS ONGOING TO EVOLVE TO
CONVECTIVE COMPLEX THAT WILL MOVE SLOWLY SOUTHEAST THROUGH 06Z FOR
LIKELY POPS OVER THE SOUTHWEST. FURTHER NORTH AND EAST OVERNIGHT
POPS TAPERED OFF. BEYOND THUNDERSTORMS THE LOW CEILING WILL RETURN
WESTWARD OVERNIGHT FOR STRATUS AND AREAS OF FOG FRIDAY MORNING.
LOWS TEMPERATURES IN THE UPPER 50S TO MID 60S.

LONG RANGE MODELS ARE SIMILAR WITH BUILDING HEIGHTS TO THE WEST
FRIDAY THROUGH SUNDAY. THE STATIONARY/DECAYING FRONT LINGERS TO
THE WEST THAT WILL REMAIN A FOCUS FOR THUNDERSTORMS EACH DAY. THE
UPPER RIDGE BUILDS AND DEVELOPS EAST TO THE HIGH PLAINS MONDAY FOR
MORE ISOLATED CONVECTION THROUGH WEDNESDAY. DAYTIME HIGHS TO
TREND UPWARDS INTO THE 90S MONDAY THROUGH WEDNESDAY.

&&

.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z THURSDAY EVENING)
ISSUED AT 629 PM CDT WED AUG 6 2014

SCATTERED THUNDERSTORMS IN WESTERN NEBRASKA ARE LIKELY TO DECREASE
SIGNIFICANTLY IN COVERAGE AS THE HEAT OF THE DAY WANES. ACCORDING TO
THE CURRENT RADAR TREND...THUNDERSTORMS IN AND AROUND OGA WILL MOVE
NEAR LBF AROUND 01Z. HOWEVER...WITH THE COVERAGE BEING SPOTTY...
THERE IS STILL UNCERTAINTY IF THUNDER WILL OCCUR AT LBF. STILL IT
WILL BE CLOSE ENOUGH THAT INCLUDING VCTS IN THE TAF IS
APPROPRIATE.

LATER TONIGHT...WIDESPREAD STRATUS WILL BRING LOW CEILINGS TO MUCH
OF CENTRAL AND NORTHERN NEBRASKA. IN THE NORTH...OUR CONFIDENCE IS
HIGH THAT THE CEILINGS WILL BE BELOW 1000 FEET AGL. THAT WOULD
INCLUDE VTN...ANW...ONL AND BBW. FARTHER SOUTH AND WEST...THAT
IS...MHN...TIF...LBF AND OGA...THERE IS MORE UNCERTAINTY.
