AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
711 AM CDT WED APR 2 2014

.UPDATE...
ISSUED AT 707 AM CDT WED APR 2 2014

PRECIPITATION CHANCES HAVE BEEN UPDATED ACROSS NORTHERN SHERIDAN
AND NORTHWEST CHERRY COUNTIES FOR THIS MORNING AS OBSERVATIONS IN
THE AREA ARE INDICATING THE COLUMN HAS BECOME SATURATED...SO LIGHT
SNOW IS NOW REACHING THE GROUND. THE MAIN AREA OF PRECIPITATION IS
CURRENTLY OVER THE FAR NORTHERN PART OF THE STATE AND WILL
CONTINUE TO LIFT NORTH THROUGH THE MORNING...WITH CHANCES BECOMING
LOWER INTO THE LATE MORNING HOURS.

ALSO...NEWEST MODEL RUNS SHOWING MORE OF A DRIZZLE SIGNAL FOR
THIS AFTERNOON AND EVENING AS THE SATURATED LAYER STAYS ABOVE -10C
INDICATING NO ICE IN THE CLOUDS. SO MAY NEED TO ADJUST WEATHER
TYPE IN THE FORECAST. DURING TIME OF ANTICIPATED DRIZZLE SURFACE
TEMPERATURES LOOK TO STAY JUST ABOVE THE FREEZING MARK. BUT ONLY A
FEW DEGREES COULD CHANGE DRIZZLE TO FREEZING DRIZZLE. NO CHANGES
HAVE BEEN MADE AS OF NOW BUT WILL NEED TO WATCH THIS TREND IN THE
COMING HOURS.

.SHORT TERM...(TODAY AND TONIGHT)
ISSUED AT 401 AM CDT WED APR 2 2014

AT 08Z...WATER VAPOR IMAGERY SHOWED WEAK MID/UPPER LEVEL RIDGING
OVER NEBRASKA...WITH A BROAD TROUGH CENTERED OVER THE WEST COAST.
IN THIS TROUGH...TWO SEPARATE CIRCULATIONS WERE NOTED. THE FIRST
OVER SOUTHERN IDAHO AND THE SECOND MOVING INTO CENTRAL CALIFORNIA.
VERY WEAK PERTURBATIONS WERE COMING OUT OF THE TROUGH INTO THE
CENTRAL PLAINS OVERNIGHT WHICH WILL CONTINUE THROUGH THE NEXT 12
HOURS OR SO. THERE WAS ISENTROPIC UPGLIDE ONGOING ACROSS WESTERN
NEBRASKA OVERNIGHT...WHICH WAS ALLOWING WEAK PRECIPITATION TO
DEVELOP OVER THE PANHANDLE INTO THE WESTERN SANDHILLS.
HOWEVER...PLENTIFUL DRY AIR IN THE LOW LEVELS WAS KEEPING ANY
PRECIPITATION FROM REACHING THE SURFACE AS CEILINGS WERE
CONTINUING TO BE AT OR ABOVE 9K FEET. THE COLUMN WAS SLOWLY MOVING
TOWARDS SATURATION IN THESE AREAS SO MAY BE GETTING A FEW FLURRIES
HERE AND THERE...BUT NOTHING MEASURABLE UNTIL FULL SATURATION
OCCURS.

FOR TODAY AND TONIGHT...THE TWO UPPER LEVEL CIRCULATIONS WILL STAY
SEPARATED AS THE NORTHERN SYSTEM LIFTS INTO NORTH DAKOTA THROUGH
TONIGHT...WHILE THE SOUTHERN SYSTEM MOVES ACROSS THE FOUR CORNERS
AND INTO COLORADO BY THURSDAY MORNING. AS THIS OCCURS...WILL
CONTINUE TO KEEP GETTING WEAK WAVES OF ENERGY MOVING ACROSS NEBRASKA
TO BRING ENHANCED LIFT TO THE AREA FROM TIME TO TIME THROUGH THE
DAY. ALTHOUGH THE AIR IS BECOMING SATURATED ACROSS WESTERN NEBRASKA
CURRENTLY...EASTERLY LOW LEVEL FLOW WILL KEEP INGESTING DRY AIR INTO
THE REGION TO LIMIT THE AMOUNT OF PRECIPITATION POTENTIAL THROUGH
THE DAY. FROM MONITORING SOUNDINGS AND CROSS SECTIONS...JUST DON/T
GET A GOOD PERIOD WITH GOOD LIFT AND AMPLE MOISTURE THROUGH TODAY TO
GIVE GOOD CONFIDENCE ON MEASURABLE PRECIPITATION SO DID DECREASE
CHANCES SLIGHTLY FOR THE DAYTIME HOURS. THAT BEING SAID...MAY BE TOO
HIGH STILL WITH PRECIPITATION CHANCES...ESPECIALLY OVER NORTH
CENTRAL NEBRASKA.

MOISTURE DOES IMPROVE OVERNIGHT AS THE SOUTHERN UPPER LOW GETS
CLOSER. BY 12Z THURSDAY...THE 700MB LOW IS CENTERED OVER SOUTHWEST
NEBRASKA...WITH A DEFORMATION BAND STARTING TO SET UP FROM NORTHERN
COLORADO INTO THE NEBRASKA PANHANDLE THROUGH THE NIGHT-TIME HOURS.

TEMPERATURES WILL STAY BELOW NORMAL TODAY...WITH HIGHS IN THE 30S
AND 40S. PRECIPITATION WILL BE SNOW ACROSS NORTHWEST NEBRASKA WHERE
THE COLDER AIR RESIDES...WHICH WILL TRANSITION TO A RAIN/SNOW MIX TO
RAIN GOING EAST AND SOUTH. THEN TONIGHT...THE COLDER AIR WILL BE
PULLED SOUTHWARD...BUT PORTIONS OF SOUTHERN INTO NORTH CENTRAL
NEBRASKA WILL CONTINUE TO HAVE AT LEAST A MIX OF LIQUID
PRECIPITATION THROUGH 06Z AS SURFACE TEMPERATURES REMAIN ABOVE THE
FREEZING MARK. SHORTLY AFTER 06Z...ALL AREAS SHOULD SEE THE SWITCH
TO SNOW.

.LONG TERM...(THURSDAY THROUGH TUESDAY)
ISSUED AT 401 AM CDT WED APR 2 2014

ANOTHER MAJOR SPRING STILL APPEARS ON TRACK FOR THE PLAINS ON
THURSDAY AND THURSDAY NIGHT. THE NAM REMAINS FAIRLY DRY FOR THE
CWA...WHILE THE REST OF THE MODELS PRODUCE A BAND OF SNOW ACROSS
THE CENTRAL OR EASTERN PARTS OF THE CWA. THE UPPER LEVEL LOW IS IN
FAIRLY GOOD AGREEMENT AMONGST ALL THE MODELS...ALTHOUGH THE SFC
LOW AS IT PUSHES ACROSS KS AND LIFTS INTO THE MID MISS RVR
VALLEY DOES SHOW MORE VARIABILITY. THE BIGGEST DIFFERENCE IS THE
AMOUNT OF MOISTURE TO WORK WITH...AND HOW FAR WEST OF THE UPPER
LOW IT CAN PUSH...IN THE WRAP AROUND. THE NAM IS A DRY
OUTLIER...ESPECIALLY ACROSS THE NW CWA WHERE LITTLE TO NO QPF IS
ACCUMULATED. THE GEM/ECMWF/UKMET ARE FURTHEST WEST AND SHOW SOME
AGREEMENT WITH THE DEFORMATION BAND. MOISTURE TRANSPORT FROM THE
GULF IS GOOD...ESPECIALLY ON THE 295K SFC...ALTHOUGH IT IS SHORT
LIVED. THIS RESULTS IN SOME CONCERN ABOUT SNOWFALL ACCUMULATIONS.
ALSO THIS WILL BE ANOTHER DAYTIME ACCUMULATION...FOR THE MOST
PART...AND WILL HAVE TO BATTLE SOME MELTING. FORECAST FOR NOW WILL
HAVE THE HIGHEST TOTALS ACROSS N CENTRAL AS THE SNOW LINGERS INTO
THURSDAY NIGHT. WILL HAVE TO MONITOR CLOSELY AS THE BAND SETS UP
EARLY THURSDAY. IF THE BAND BECOMES TIGHTER...A POSSIBILITY AS
MODELS THIS FAR OUT STRUGGLE SOMETIMES WITH THE WIDTH OF THE
DEFORMATION BAND...SNOWFALL COULD BE GREATER. AS IT STANDS SNOW
ACCUMULATIONS REMAIN BELOW 6 INCHES AND NO HEADLINE WILL BE
ISSUED. NORTHWEST WINDS WILL BE GUSTY...25 TO 35 MPH SO WHERE
THERE IS SNOW FALL OPEN AREAS MAY SEE SOME BLOWING SNOW.

SYSTEM PUSHES INTO THE GREAT LAKES THURSDAY NIGHT INTO FRIDAY.
CLEARING FROM THE WEST TO EAST THROUGHOUT THURSDAY NIGHT. AS SKIES
CLEAR...TEMPS WILL DROP. FORECAST FOLLOWED CLOSE TO OR BELOW
GUIDANCE AS ANTICIPATE AT LEAST A LIGHT SNOW COVER...AND SOME
AREAS SEVERAL INCHES OF A SNOW COVER...AND LOCAL STUDY SUGGESTS
LOWS CAN BE UP TO 10 DEGREES BELOW GUIDANCE WITH A NEW SNOW PACK
AND CLEAR SKIES. LOWS EASILY INTO THE LOWER TO MID 20S...AND COULD
SEE SOME TEENS.

REST OF THE EXTEND REMAINS ACTIVE WITH SEVERAL CLIPPERS TO PUSH
ACROSS THE AREA THROUGH THE FIRST PART OF NEXT WEEK. TIMING WITH
THE NW SYSTEMS WILL BE IRONED OUT AS WE GET CLOSER...AND LOW POPS
CONTINUE. TEMPS STILL CHILLY THROUGH THE WEEKEND...HOWEVER A
WARMING TREND IS POSSIBLE NEXT WEEK AS A RIDGE BUILDS ACROSS THE
SOUTHWEST CONUS. AS THE RIDGE BUILDS NEXT WEEK...THE CLIPPERS
SHOULD TRACK TO THE NORTH...AND A DRY PERIOD IS POSSIBLE FOR THE
MIDDLE OF NEXT WEEK.

.AVIATION...(FOR THE 12Z TAFS THROUGH 12Z THURSDAY MORNING)
ISSUED AT 707 AM CDT WED APR 2 2014

CONDITIONS WILL BE DETERIORATING ACROSS SOUTHERN NEBRASKA OVER THE
NEXT 24 HOURS AS LOW LEVEL MOISTURE MOVES INTO THE REGION. VFR
CEILINGS WILL PERSIST AT KLBF THROUGH THE MORNING...WHILE A FEW
HOURS OF LIGHT RAIN IS POSSIBLE CENTERED AROUND 18Z. CEILINGS WILL
STAY MVFR OR BETTER THROUGH THE EVENING...THEN CEILINGS ARE
EXPECTED TO DROP TO 1K FT OR LESS AFTER 06Z. OVER NORTHERN
NEBRASKA /IMPACTING THE KVTN TERMINAL/...LOW CLOUDS AT HEIGHTS
BELOW 1K FEET HAVE BEEN MOVING ACROSS THE AREA FROM TIME TO TIME
THIS MORNING AND WITH MODELS KEEPING THE LOW LEVEL MOISTURE IN
PLACE...KEPT MENTION OF SCT008 IN THE FORECAST FOR THIS MORNING.
MAY GET A PERIOD OF -SN EARLY THIS AFTERNOON...THEN WITH LOSS OF
ICE IN THE CLOUDS...BELIEVE DRIZZLE WILL BE PRIMARY PRECIPITATION
TYPE FOR LATER THIS AFTERNOON AND EARLY EVENING. TEMPERATURES LOOK
TO BE ABOVE FREEZING SO NO MENTION OF FZ DZ AT THIS TIME. BEYOND
03Z...KEPT LOWERED VISIBILITIES AND IFR CEILINGS IN THE FORECAST
DUE TO EXPECTED REMNANT LOW LEVEL MOISTURE.
