AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
1216 PM CST TUE JAN 6 2015

ISSUED AT 335 AM CST TUE JAN 6 2015

EARLY THIS MORNING 1036MB SURFACE HIGH ANCHORED OVER CHAMBERLAIN
SOUTH DAKOTA. LIGHT WINDS AND CLOUDY OVER WESTERN NEBRASKA. COLDEST
TEMPERATURES OVER NORTH CENTRAL KONL. 850MB TEMPERATURES NEAR -5C
EARLY THIS MORNING. FLURRIES HAVE ENDED OVER NORTH CENTRAL NEBRASKA
AND WILL LET THE ADVISORY GO WITH ZONE ISSUANCE. NORTHERN PLAINS

WILL ROTATE A TROUGH THROUGH THE NORTHERN PLAINS DRAWING A 1050MB
SURFACE HIGH PRESSURE ACROSS THE NORTHERN PLAINS WITH ASSOCIATED
ARCTIC AIR. 850MB TEMPERATURES OVER WESTERN AND NORTH CENTRAL
NEBRASKA WEDNESDAY MORNING -20C. UPSLOPE FLOW COMBINED WITH VERY
COLD TEMPERATURES WILL BRING SNOW TO WESTERN NEBRASKA BEGINNING
NORTH TUESDAY AFTERNOON AND TRANSITIONING SOUTH OVER NIGHT.
GENERALLY LESS THAN AN INCH OF SNOW EXPECTED. WINDS NOT AS STRONG
WITH THIS SYSTEM AS THE LAST. HIGHLIGHTS NOT EXPECTED FOR SNOW. VERY
COLD AIR COMBINED WITH SNOW COVER WILL APPROACH WIND CHILL
HIGHLIGHTS OVER THE NORTH EARLY WEDNESDAY MORNING. BORDERLINE AND
HAVE LEFT OUT FOR NOW.

HIGHS TODAY WILL BE ON THE COOL SIDE WITH FRONT MOVING IN NORTH
AROUND 18Z AND THEN STRONG COLD AIR ADVECTION THROUGH THE DAY. HAVE
GONE SEVERAL DEGREES BELOW GUIDANCE WITH MODELS SLOW TO RESPOND.
TONIGHTS LOW TEMPERATURES EXPECTED IN THE NEGATIVE NUMBERS OVER ALL
EXCEPT SOUTHWEST NEBRASKA.

.LONG TERM...(WEDNESDAY THROUGH MONDAY)
ISSUED AT 335 AM CST TUE JAN 6 2015

12Z WEDNESDAY AND BEYOND. A POLAR AIRMASS WILL SLIDE SOUTHEAST OF
THE ROCKIES ACROSS THE PLAINS ON WEDNESDAY PROVIDING FOR ANOTHER
ROUND OF BITTERLY COLD TEMPERATURES AND DANGEROUSLY LOW WIND
CHILLS. THE ARCTIC FRONT WILL BE WELL SOUTH OF FORECAST AREA BY
NOON WEDNESDAY...WITH A 1055MB PLUS HIGH SETTLING ATOP THE
FORECAST AREA MIDDAY. THE RELAXING PRESSURE GRADIENT WILL ALLOW
APPARENT T/S TO RISE ABOVE ADVISORY THRESHOLDS BY EARLY
AFTERNOON...HOWEVER THE BRUNT OF THE CAA WILL TARGET OUR
NORTHEASTERN ZONES AND POINTS EAST...THERE WE MAY SEE WIND CHILL
READINGS IN THE MINUS TEEN RANGE THROUGH THE AFTERNOON HOURS. WILL
RE-EVALUATE WIND CHILLS TODAY...AND ISSUE APPROPRIATE HEADLINES
THEN.

ANOTHER FORECAST CONCERN IS THE POTENTIAL OF LIGHT SNOW AND/OR
FLURRIES CONTINUING WEDNESDAY MORNING ACROSS OUR SOUTHWEST. THE CP
AIRMASS IS ANOMALOUSLY STRONG LEADING TO RATHER LOW DENDRITIC GROWTH
ZONES...WHICH IS SHOWN TO BE MODESTLY SATURATED AT TIMES...FLURRIES
AND/OR LIGHT SNOW IS POSSIBLE.  THIS IS DESPITE THE DRY CONDITIONS
THE MODELS ARE INDICATING BEYOND 12Z WEDNESDAY.

RETURN FLOW TAKES CONTROL ON THE BACKSIDE OF THE EASTWARD DEPARTING
ARCTIC HIGH.  H85 TEMPERATURES ARE SHOWN TO WARM ABOVE 10C ACROSS
SOUTHWEST NEBRASKA BY 12Z THURSDAY...SFC TEMPERATURES WILL
WARM...HOWEVER THE WARMUP WILL BE SHORT-LIVED AS THE NEXT ARCTIC
AIRMASS DIVES SOUTH ACROSS THE CENTRAL PLAINS THURSDAY AFTERNOON.
HIGHS IN THE TEEN RETURN FOR FRIDAY...SUB ZERO AND SINGLE DIGIT LOWS
WILL CONTINUE INTO THE WEEKEND.  THE FRONT MAY BRING ANOTHER
OPPORTUNITY FOR LIGHT PRECIPITATION...HOWEVER AT THIS POINT -FZDZ IS
FAVORED AS PROFILES REVEAL SUPER-COOLED SATURATED LOW LEVELS WITHOUT
ANY INFLUENCE OF ICE IN THE DGZ.  TEMPERATURES WARM ONCE AGAIN FOR
SATURDAY AS RETURN FLOW IS ESTABLISHED ON THE BACKSIDE OF THE
DEPARTING HIGH.  THE ROLLER-COASTER OF TEMPERATURES CONTINUES INTO
EARLY NEXT WEEK AS AMPLIFIED NORTHERLY FLOW USHERS ADDITIONAL ARCTIC
FRONTS THROUGH THE REGION.  THERE ARE INDICATIONS OF A PATTERN
CHANGE EARLY NEXT WEEK...WHICH WOULD SHUT DOWN THE TAP OF ARCTIC AIR
ACROSS THE PLAINS...AT LEAST FOR A WHILE.

ISSUED AT 1155 AM CST TUE JAN 6 2015

AFTERNOON...WITH CEILINGS LOWERING INTO THE MVFR CATEGORY ALONG
WITH SCATTERED SNOW SHOWERS. MOST OF THE LOWER MVFR CEILINGS WILL
REMAIN ALONG AND SOUTHWEST OF A KVTN TO KANW TO KBBW LINE.
SCATTERED SNOW SHOWERS ARE ALSO POSSIBLE AS THE FRONT MOVES
THROUGH. CONDITIONS WILL IMPROVE LATER TONIGHT...AS DRIER AIR
