AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
343 AM CDT WED SEP 23 2015

.SHORT TERM...(TODAY AND TONIGHT)
ISSUED AT 343 AM CDT WED SEP 23 2015

SHOWERS AND THUNDERSTORMS MOVING ACROSS SOUTHWEST NEBRASKA MOVING
NORTH NORTHEAST INTO THE NEBRASKA SANDHILLS EARLY THIS MORNING.
STATIONARY BOUNDARY LYING ACROSS THE SOUTHERN NEBRASKA PANHANDLE AND
THEN EAST JUST NORTH OF INTERSTATE 80 INTO EASTERN NEBRASKA. VERY
SHARP CUTOFF TO THE PRECIPITATION TO THE WEST. BACK EDGE TO CURRENT
PRECIPITATION ALONG KANSAS NEBRASKA BORDER WITH ANOTHER ROUND SOUTH
OF GOODLAND. WILL USE A BLEND OF NAM AND GFS FOR THE NEAR TERM
FORECAST WITH A GLANCE AT HRR. WOULD HAVE MORE CONFIDENCE IF QPF
FROM CURRENT AREA OF PRECIPITATION WAS HIGHER. HAVE ADJUSTED POPS
ACROSS WESTERN NEBRASKA WITH THE EASTERN NEBRASKA PANHANDLE BEING
LEFT OUT OF MOST OF THE PRECIPITATION AND A SHARP CUTOFF OVER
SOUTHWEST NEBRASKA INTO NORTHEAST COLORADO. NORTH OF THE FRONT TODAY
IN THE SANDHILLS TEMPERATURES WILL STRUGGLE AGAIN IN THE UPPER 60S
TO AROUND 70. SOUTH OF THE FRONT TEMPERATURES GENERALLY IN THE 70S
WITH TEMPERATURES AROUND 80 AT IMPERIAL.

HAD A COUPLE OF INCHES OF RAIN EARLY TONIGHT OVER NORTH CENTRAL KEYA
PAHA AND BOYD COUNTIES. STRONG SIGNALS FOR TRAINING PRECIPITATION
OVER NORTH CENTRAL NEBRASKA THIS EVENING AND OVER NIGHT.
COORDINATION BETWEEN OAX AND FSD HAVE A FLASH FLOOD WATCH OVER BOYD
AND HOLT COUNTIES BEGINNING TODAY AT 18Z AND RUNNING THROUGH 12Z
THURSDAY. GONE WITH DEFINITE POPS AND MODERATE RAIN OVER THIS AREA.
LOWS TONIGHT IN THE MID 50S.

.LONG TERM...(THURSDAY THROUGH TUESDAY)
ISSUED AT 343 AM CDT WED SEP 23 2015

LINGERING PRECIPITATION CHANCES ON THURSDAY INTO POSSIBLY FRIDAY IS
THE MAIN FORECAST CHALLENGE IN THE EXTENDED.

THE REMNANTS OF A TROPICAL LOW WILL CONTINUE TO RELUCTANTLY WOBBLE
EAST ACROSS EASTERN PORTIONS OF THE FORECAST AREA ON THURSDAY.
UPGLIDE CENTERED ALONG THE 305K SURFACE WILL SHIFT EAST THROUGH THE
DAY...BUT STILL WILL PROVIDE FOR QPF ACROSS OUR NORTHEASTERN AND
EASTERN ZONES. WEAK INSTABILITY DEPICTED IN PROXIMITY SOUNDINGS ACROSS
NORTH CENTRAL NEBRASKA ON THURSDAY MAY PROVIDE FOR A FEW RUMBLES
OF THUNDER...SO WILL CONTINUE A MENTION. THE SLOW SYSTEM MOTION
AND ABOVE NORMAL PWATS WOULD SUGGEST SOME HEAVY RAIN POTENTIAL
INTO EARLY THURSDAY...ESPECIALLY IF A CONVECTIVE ELEMENT IS
REALIZED. BUT IT SHOULD BE NOTED THAT THE ATMOSPHERE WILL BECOME
INCREASINGLY UNFAVORABLE FROM WEST TO EAST AS DRY AIR WORKS IN BEHIND
THE ADVANCING REMNANT LOW.

THERE ARE NOTABLE DIFFERENCES BETWEEN THE ECMWF AND GFS IN THE
HANDLING OF THE TROPICAL LOW.  THE GFS LIFTS THE LOW
NORTHEAST...WHEREAS THE THE EC INITIALLY LIFTS NORTHEAST...BUT THEN
DROPS THE LOW SOUTH INTO CENTRAL KANSAS.  IF THE EC CAMP IS ONTO
SOMETHING...THEN RAINSHOWERS/THUNDERSTORMS CHANCES WOULD LINGER WELL
INTO FRIDAY...ESPECIALLY ACROSS SOUTHEASTERN PORTIONS OF THE FORECAST
AREA.

FRIDAY AND INTO THE WEEKEND...MID-LEVEL RIDGING WILL EXPAND NORTHEAST
ACROSS THE PLAINS FROM THE DESERT SOUTHWEST. THIS WILL ALLOW FOR A
GRADUAL WARMUP. ENOUGH CLOUDINESS ASSOCIATED WITH THE SLOWLY
DEPARTING LOW WILL KEEP TEMPERATURES SEASONAL THURSDAY AND
POSSIBLY FRIDAY...BUT INTO THE WEEKEND TEMPERATURES RETURN ABOVE TO
WELL ABOVE AVERAGE.

A OVERALL LACK OF TROPOSPHERIC OMEGA WILL ALLOW FOR A DRY FORECAST
THIS WEEKEND. THE NEXT SHOT AT QPF ARRIVES EARLY NEXT WEEK WITH THE
APPROACH OF FAVORABLE UPPER LEVEL DYNAMICS AND A WEAK SHORTWAVE.  A
FRONT WILL BE FORCED THROUGH THE CWA ON MONDAY...PROVIDING FOR A
SLIGHT COOLDOWN TUESDAY.

.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z WEDNESDAY NIGHT)
ISSUED AT 244 AM CDT WED SEP 23 2015

FOG AND STRATUS IN NORTHERN NEBRASKA ARE LIKELY TO CONTINUE UNTIL
SHOWERS/THUNDERSTORMS AGAIN MOVE INTO THE AREA AROUND 10Z.
ANOTHER...MORE ORGANIZED THUNDERSTORM SYSTEM IN SOUTHWEST NEBRASKA
INITIALLY WILL CONTINUE AT LEAST INTERMITTENTLY THROUGH THE NIGHT
AND SPREAD INTO CENTRAL NEBRASKA. AFTER 11Z...THE SYSTEM WILL BECOME
DOMINATED BY A STEADY LIGHT TO MODERATE RAIN WITH VISIBILITY AT OR
BELOW 3SM WITH CEILING 1000-1500 FEET AGL.
