AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
533 PM CST MON NOV 16 2015

.SYNOPSIS...
ISSUED AT 343 PM CST MON NOV 16 2015

CLOSED LOW OVER 4 CORNERS TODAY WILL BE MOVING OUT ONTO THE CENTRAL
PLAINS TONIGHT. RIDGE FROM THE SOUTHEAST CONUS THROUGH THE GREAT
LAKES INTO THE HUDSON BAY.

&&

.SHORT TERM...(THIS EVENING THROUGH TUESDAY)
ISSUED AT 343 PM CST MON NOV 16 2015

TONIGHT AND TOMORROW.

THE IMMEDIATE CONCERN IN THE SHORT TERM INVOLVES THE POSSIBILITY OF
SEVERE THUNDERSTORMS ACROSS SOUTHWEST NEBRASKA.  MOISTURE CONTINUES
TO STREAM NORTH ACROSS THE CENTRAL PLAINS IN ADVANCE OF A DEVELOPING
SFC LOW OVER SE COLORADO.  AN AXIS OF 50F TD HAS NOSED INTO
SOUTHWEST NEBRASKA...MAINLY OVER HAYES AND FRONTIER COUNTIES AND
POINTS EAST. MODERATE INSTABILITY IS DEVELOPING AS LAPSE RATES
INCREASE WITH THE APPROACH OF A THE FOUR CORNERS UPPER TROUGH. 50KTS
OF DEEP SHEAR WILL PROMOTE STORM ROTATION AND MAINTENANCE...WHICH
COULD PRODUCE HAIL TO THE SIZE OF QUARTERS AND WIND GUSTS TO 60 MPH.
THE SHEAR ALONG AND NEAR AN ADVANCING BAROCLINIC ZONE FROM THE SOUTH
WILL ALLOW FOR THE POSSIBILITY OF AN ISOLATED TORNADO.  THE ACTIVITY
MAY SPREAD NORTH OF INTERSTATE 80 AFTER DARK.

THE WINTER STORM...FORECAST CONFIDENCE IS SUFFICIENT FOR THE
ISSUANCE OF WINTER WEATHER HEADLINES FOR A LARGE PORTION OF WEST
CENTRAL NEBRASKA.  THE WINTER STORM WATCH WAS UPGRADED TO A WINTER
STORM WARNING AS THE MODELS CONTINUE TO PLACE SOUTHWEST NEBRASKA IN
THE CROSSHAIRS.  A WINTER WEATHER ADVISORY HAS BEEN ISSUED
BOOKENDING TO THE NORTH AND EAST OF THE WARNING AREA TO ACCOUNT FOR
LESSER...BUT STILL POTENTIALLY SIGNIFICANT ACCUMULATIONS.  THERE
REMAINS UNCERTAINTY IN THE FORECAST AS LOWER TO MID LEVEL
TROPOSPHERIC TEMPERATURES ARE PROGGED TO BE ONLY MARGINALLY
SUPPORTIVE FOR SNOW. IN FACT...AS WAS THE CASE WITH LAST WEEK/S
SYSTEM...IT WILL TAKE STRONG DYNAMIC COOLING UNDER THE EVENTUAL
DEFORMATION BAND TO SUFFICIENTLY COOL TEMPERATURES THAT SUPPORT
ACCUMULATIONS.  AT THIS TIME...THE MODEL CONSENSUS PLACES THIS BAND
ACROSS SOUTHWEST NEBRASKA NORTHEAST THROUGH WEST CENTRAL PORTIONS OF
THE SANDHILLS. THE MODELS RELUCTANTLY DEVELOP THIS BAND EAST...BUT
WEAKEN IT THROUGH THE DAY ON TUESDAY.  THUS THE GREATEST OPPORTUNITY
FOR HEAVY SNOW IS ACROSS SOUTHWEST NEBRASKA. WE MUST CAUTION HOWEVER
THAT CONVECTIVE STORMS /JUST DEVELOPING/ WELL SOUTH AND EAST OF THE
EVENTUAL DEFORMATION MAY FORCE THE DEVELOPING LOW SOUTH AND EAST AS
WELL.  IN ADDITION...THE DEEP MOISTURE FEEDING INTO THE BANDED SNOW
MAY DIRECT EAST.  IF THIS WERE TO OCCUR...THE HEAVIEST QPF/SNOW
ACCUMULATIONS COULD SHIFT EAST OR SOUTH...WHICH WOULD REQUIRE AN
EASTWARD SHIFT IN OUR HEADLINES IF TEMPERATURES SUPPORT SNOW.  THIS
IS A DYNAMIC STORM...WE ARE FOCUSING ON THE POTENTIAL...BUT
REMEMBER...NOT ALL AREAS WILL SEE SIGNIFICANT SNOW.  THIS MAY BE A
CASE WHERE WESTERN PORTIONS OF LINCOLN COUNTY SEE UPWARDS TO 10
INCHES OF SNOW...AND EASTERN PORTIONS SEE LESS THAN AN INCH. UPDATES
MAY BE NEEDED TO THE FORECAST...ALL INTERESTS NEED TO MONITOR THE
WINTER ASPECT OF THIS STORM CLOSELY AS A SMALL WOBBLE IN A MODEL
COULD AMOUNT TO MAJOR DIFFERENCES IN THE FORECAST SNOW.

.LONG TERM...(TUESDAY NIGHT THROUGH MONDAY)
ISSUED AT 343 PM CST MON NOV 16 2015

TUESDAY NIGHT DEFORMATION ZONE WITH ENHANCED VERTICAL
MOTIONS WILL MOVE SLOWLY NORTH NORTH EAST ACROSS WESTERN NEBRASKA
ROUGHLY ALIGNED ALONG A LINE FROM NORTH PLATTE TO AINSWORTH. SNOW
WILL CONTINUE ALONG THIS LINE OVER NIGHT WITH A MIX IN THE ONEILL
VICINITY. WINDS WILL SLOWLY DIMINISH OVER NIGHT. TEMPERATURES
TOWARM INTO THE 40S ON WEDNESDAY WITH RAIN ENDING IN THE
ONEILL VICINITY THROUGH THE DAY. HAVE CUT TEMPERATURES BACK WITH
SNOWCOVER. WEDNESDAY HAVE COOLER TEMPERATURES OVER SNOW COVER
WITH CLEARING SKIES AND WINDS DROPPING OFF. THURSDAY AS THE UPPER
LOW MOVES NORTHEAST TOWARDS THE HUDSON BAY IT WILL DRAW MUCH
COOLER AIR FROM CENTRAL CANADA INTO THE NORTHERN PLAINS WITH
TEMPERATURES DROPPING INTO THE 30S AND 40S OVER WESTERN NEBRASKA.
WITH SOME MOISTURE IN PLACE FRIDAY AND ANOTHER SHOT OF COLD AIR
WITH HIGHS IN THE 30S ANOTHER ROUND OF LIGHT SNOW FRIDAY.
TEMPERATURES WARM AS HIGH PRESSURE BUILDS IN FROM THE WEST
THROUGH THE WEEKEND WITH HIGHS IN THE 40S AND DRY.
