AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
627 PM CDT TUE SEP 22 2015

.SYNOPSIS...
ISSUED AT 314 PM CDT TUE SEP 22 2015

H5 ANALYSIS THIS MORNING HAS RIDGING EXTENDING FROM
TEXAS NWD INTO THE CENTRAL PLAINS. CLOSED LOW PRESSURE WAS LOCATED
EAST OF THE RIDGE OVER SERN ALABAMA WITH ANOTHER LOW LOCATED OVER
CENTRAL ARIZONA. THE LATTER IS THE REMNANTS OF A TROPICAL
DEPRESSION WHICH TRACKED ACROSS SOUTHERN CALIFORNIA AND NRN BAJA CA
OVER THE PAST 24 HOURS. CURRENT WV IMAGERY HAS THIS FEATURE TRACKING
THROUGH FAR NERN AZ. A SECOND LEAD SHORTWAVE WAS LOCATED OVER SERN
COLORADO ATTM. ACROSS WESTERN AND NORTH CENTRAL NEBRASKA...A WARM
FRONT EXTENDED FROM NERN COLORADO...ROUGHLY ALONG THE FAR SRN TIER
OF COUNTIES IN NEBRASKA. NORTH OF THE FRONT...EASTERLY WINDS AND LOW
LEVEL CLOUDINESS WAS PREVALENT THIS MORNING. AS OF 3 PM CDT...THIS
STRATUS AND FOG HAD BURNED OFF SOUTH OF A LINE FROM ANTIOCH TO
STAPLETON TO BROKEN BOW. NORTH OF THIS LINE...STRATUS HAS HELD IN
PLACE THIS AFTERNOON AND HAS LED TO COOL TEMPERATURES IN THE 60S TO
AROUND 70. ELSEWHERE TEMPS WERE IN THE 70S AND 80S WITH READINGS
APPG 90 IN THE FAR SOUTHWESTERN CWA. IN ADDITION TO LOW
CLOUDS...ELEVATED INSTABILITY WAS PRESENT ON THE LATEST VIS
SATELITE IMAGERY WITH CONVECTIVE CLOUDS DEVELOPING OVER PORTIONS
OF CENTRAL NEBRASKA...INVOF OF A MID LEVEL FRONT.

&&

.SHORT TERM...(THIS EVENING THROUGH WEDNESDAY)
ISSUED AT 314 PM CDT TUE SEP 22 2015

MAIN FORECAST CONCERN OVER THE SHORT TERM...THROUGH WEDNESDAY
AFTERNOON...IS PRECIPITATION. ABUNDANT MOISTURE IS SET TO MOVE INTO
WESTERN NEBRASKA OVER THE NEXT 24 HOURS WHICH MAY LEAD TO
WIDESPREAD RAINFALL TOTALS GREATER THAN ONE INCH.

A WARM FRONT DRAPED ACROSS THE FORECAST AREA...GENERALLY ALONG
INTERSTATE 80...WILL BE THE FORCING MECHANISM FOR THE PRECIPITATION.
A BROAD AREA OF ISENTROPIC UPGLIDE IS SHOWN BY THE NAM...PROMINENTLY
SEEN ON THE 305K SURFACE LATE THIS EVENING ACROSS THE NORTHERN HALF
OF THE FORECAST AREA. STRATUS HAS BEEN PRESENT OVER THE AREA ALL
DAY...INDICATING SUFFICIENT LOW LEVEL MOISTURE. WITH MORE MID LEVEL
MOISTURE AND THE NOSE OF A 250HPA JET ARRIVING THIS EVENING...HAVE
INCREASED POPS FROM 23/00Z TO 23/06Z ALONG AND NORTH OF U.S. HIGHWAY
20.

THE MORE SUBSTANTIAL WAVE ENTERS THE SOUTHWEST PORTION OF THE
FORECAST AREA TOWARD 23/06Z. AS THE SURFACE LOW DEEPENS OFF THE
FRONT RANGE AND MOVES NORTHEAST...BREEZY SOUTHERLY WINDS WILL HELP
PULL IN AMPLE MOISTURE. DEW POINTS WILL INCREASE THROUGHOUT THE
NIGHT TO NEAR 60F ACROSS THE SOUTH. STRONG ISENTROPIC UPGLIDE AT
305K EXPANDS TO NEARLY THE ENTIRE FORECAST AREA BY 23/12Z...AND NAM
FORECAST SOUNDINGS SATURATE THE COLUMN AT KLBF. ON THE EDGE OF THE
HEAVIER PRECIPITATION...WINDS MAY BE LIGHT ENOUGH TO SUPPORT SOME
PATCHY FOG AROUND DAWN. THE AREA OF CONCERN IS THE EASTERN PANHANDLE
AND FAR NORTHWEST NEBRASKA...BUT CONFIDENCE IS TOO LOW TO WARRANT
MENTION IN THE CURRENT FORECAST.

WEDNESDAY MID MORNING THROUGH THE AFTERNOON...INCREASED POPS TO
LIKELY ALONG AND EAST OF HIGHWAY 83 AS CONFIDENCE IS HIGH FOR
ACCUMULATING RAINFALL. FORECAST SOUNDINGS SHOW VERY DEEP MOIST
PROFILES AND NEAR RECORD CLIMATOLOGICAL PRECIPTABLE WATER VALUES.
DESPITE HIGH QPF VALUES...BETWEEN 0.5 AND 1.0 INCH FOR THE
AREA...NOT CONCERNED ABOUT FLOODING AS AMOUNTS ARE WELL BELOW FLASH
FLOOD GUIDANCE. WITH MARGINAL CAPE AND INSTABILITY DURING THE
AFTERNOON...NOT CONCERNED ABOUT SEVERE THUNDERSTORMS EITHER.

TEMPERATURE WISE...HAVE UPPED LOW TEMPERATURES TONIGHT A DEGREE OR
TWO TO ACCOUNT FOR PERSISTENT LOW CLOUD COVER. TRENDED TOWARD MET
GUIDANCE FOR MAX TEMPS ON WEDNESDAY...STAYING NEAR PREVIOUS FORECAST
HIGHS IN THE SOUTH AND COOLER ACROSS THE NORTH. HIGHS IN THE LOWER
70S ARE REASONABLE GIVEN CLOUD COVER AND 850HPA TEMPS OF 15 TO 17C.

.LONG TERM...(WEDNESDAY NIGHT THROUGH TUESDAY)
ISSUED AT 314 PM CDT TUE SEP 22 2015

WEDNESDAY NIGHT THROUGH FRIDAY...LINGERING PCPN CHANCES WEDNESDAY
NIGHT THROUGH THURSDAY NIGHT ARE THE MAIN FORECAST CHALLENGE IN THE
MID RANGE. THE REMNANTS OF THE BEFORE MENTIONED TROPICAL LOW WILL
TRACK SLOWLY ACROSS CENTRAL AND EASTERN PORTIONS OF THE FORECAST
AREA WEDS NIGHT INTO THURSDAY MORNING. DECENT ISENTROPIC LIFT WILL
CONTINUE ROUGHLY EAST OF A LINE FROM CODY TO IMPERIAL WEDS
EVE...THEN EAST OF A LINE FROM VALENTINE TO HAYES CENTER OVERNIGHT.
SOME DIFFERENCES WERE NOTED WITH RESPECT TO THE LOCATION OF THE BEST
ISENTROPIC LIFT WEDS NIGHT WITH THE GFS...CONFINING THE BEST LIFT TO
THE FAR EASTERN CWA...WHILE THE NAM SOLN WAS ACROSS THE CENTRAL AND
EASTERN CWA. THE NAM SOLN WAS CONSISTENT WITH YESTERDAYS SOLNS...AND
HAVE OPTED FOR A MORE WESTERLY TRACK OF THE BEST ISENTROPIC LIFT.
THAT BEING SAID...HAVE DONE LITTLE TO THE ONGOING POP FCST WHICH HAD
THE HIGHEST POPS ALONG AND EAST OF HIGHWAY 83 FOR WEDS NIGHT. AS WE
HEAD INTO THURSDAY AFTERNOON...WEAK ISENTROPIC LIFT WILL CONTINUE
ALONG AND EAST OF HIGHWAY 183 THURSDAY AFTERNOON AND EVENING WITH A
LIMITED THREAT FOR PCPN TO CONTINUE. WEST OF THIS ROUTE...LOOK FOR A
SHARP CUTOFF IN PCPN AS ISENTROPIC DOWN GLIDE AND MUCH DRIER AIR
PUSHES INTO CENTRAL PORTIONS OF THE CWA. THE REMNANTS OF THE
LOW...WILL DRIFT TO THE SSW ON FRIDAY AS A POSITIVELY TILTED RIDGE
BUILDS INTO WESTERN NEBRASKA FROM THE FOUR CORNERS. INHERITED FCST
HAD SOME SLIGHT CHANCE POPS IN THE SERN AND FAR SRN CWA FRIDAY AND
HAVE LEFT THEM IN AS THE REMNANTS OF THE LOW DRIFT SOUTH INTO WESTERN
KS. AS FOR TEMPERATURES IN THE MID RANGE...HIGHS THURSDAY WILL
STRUGGLE TO HIT 70 IN THE EAST WHERE CLOUDS WILL PERSIST...WHILE
READINGS NEAR 80 ARE EXPECTED IN THE WEST. HIGHS ON FRIDAY WILL BE
IN THE UPPER 70S TO NEAR 80. WITH RESPECT TO QPF/S OVER THE NEXT 12
TO 48 HRS...PWATS IN ASSOCIATION WITH THIS SYSTEM INCREASE TO 1.5
INCHES TONIGHT...THEN TO 1.75 INCHES IN THE EASTERN HALF OF THE CWA
ON WEDNESDAY. FOR LBF...THE 1.5 INCH PWATS TONIGHT AND TOMORROW ARE
ROUGHLY AT THE TOP END OF CLIMATOLOGY...SO THE MOISTURE FOR HEAVY
RAIN IS THERE OVER THE NEXT 12 TO 48 HRS. FOLLOWING THE NATL
GUIDANCE WHICH SEEMS TO AGREE FAIRLY WELL WITH THE LATEST ECMWF AND
NAM QPF FCST...YIELDS A LARGE SWATH OF 1 TO 2 INCHES OF RAINFALL
EAST OF A LINE FROM IMPERIAL TO VALENTINE. THIS AGREES WITH THE SREF
PLUMES FOR NORTH PLATTE...BROKEN BOW...ONEILL AND THEDFORD...WHICH
THE MEAN IS ROUGHLY 1.5 INCHES FOR THE EVENT.

FRIDAY NIGHT THROUGH TUESDAY...A POSITIVE TILTED RIDGE WILL BUILD
INTO THE CENTRAL PLAINS FROM THE FOUR CORNERS FRIDAY INTO SUNDAY
WITH DRY WEATHER EXPECTED. A BRIEF COOL DOWN WILL BEGIN NEXT WEEK AS
A PACIFIC COLD FRONT USHERS IN A GLANCING BLOW OF COOLER AIR.
ATTM...DYNAMICS FOR PCPN REMAIN NORTH OF THE AREA OVER THE
DAKOTAS...SO A DRY FCST CONTINUES. AFTER A TEMPORARY COOL DOWN ON
MONDAY...READINGS WILL REBOUND BACK INTO THE 80S AS A LARGE RIDGE OF
HIGH PRESSURE BUILDS INTO THE CENTRAL CONUS. BY WEDNESDAY NEXT
WEEK...THE ECMWF HAS A 5900 H5 HIGH OVER NWRN KS WITH H85 TEMPS IN
THE MID 20S CELSIUS...WHICH WOULD LEAD TO HIGHS IN THE 80S TO LOWER
90S...WHICH IS NEAR RECORD HIGHS FOR THE END OF SEPTEMBER.

.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z WEDNESDAY EVENING)
ISSUED AT 626 PM CDT TUE SEP 22 2015

FOG/STRATUS IN NORTHERN NEBRASKA ARE LIKELY TO CONTINUE UNTIL

SYSTEM WILL BE DOMINATED BY A STEADY LIGHT TO MODERATE RAIN WITH
MARGINAL VISUAL METEOROLOGICAL CONDITIONS.
