AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HASTINGS NE
346 PM CDT TUE APR 10 2012

.SHORT TERM...TONIGHT THROUGH WEDNESDAY. THE PRIMARY CONCERN WILL
CENTER AROUND LOW TEMPERATURES TONIGHT...WHICH WILL BE INFLUENCED BY
A TRICKY CLOUD COVER FORECAST. SOME AREAS...ESPECIALLY OUR FAR NORTH
AND NORTHEAST ZONES COULD ONCE AGAIN SEE BELOW FREEZING TEMPERATURES
LATE TONIGHT INTO EARLY WEDNESDAY MORNING.

THE GFS AND NAM BOTH INDICATE THAT A LAYER OF CLOUDS LOCATED BETWEEN
850 MB AND 700 MB WILL THICKEN ACROSS THE SOUTHWESTERN TWO THIRDS OF
OUR CWA...ESPECIALLY AFTER MIDNIGHT. DEWPOINTS ARE CERTAINLY VERY
LOW REPRESENTING THE DRY AIR MASS AND WITH LIGHT WINDS TEMPERATURES
SHOULD QUICKLY COOL THIS EVENING INTO THE EARLY MORNING HOURS.
HOWEVER...SHOULD CLOUD COVER THICKEN...THEN THAT WILL EASE THE
TEMPERATURE SLIDE AND MOST LOCATIONS THAT SEE OVERCAST SKIES SHOULD
NOT FREEZE. IT APPEARS THAT CLOUD COVER WILL BE LESS EXTENSIVE
ACROSS OUR FAR NORTHEASTERN ZONES AND THEREFORE THESE AREAS WILL
ONCE AGAIN BE MOST SUSCEPTIBLE TO ANOTHER NIGHT OF SUBFREEZING
TEMPERATURES. GRAND ISLAND...HASTINGS...KEARNEY...AND POINTS TO THE
SOUTH AND WEST SHOULD HAVE ENOUGH CLOUDS AROUND TO KEEP TEMPERATURES
JUST ABOVE FREEZING. HOWEVER...IF THE CLOUDS DO NOT FORM OR REMAIN
PERSISTENT ENOUGH OVER THE TRI CITIES DURING THE LATE NIGHT TO EARLY
MORNING HOURS THEN EVEN THE TRI CITIES COULD SEE SOME FROSTY
CONDITIONS. CONSEQUENTLY...THIS IS A VERY DIFFICULT TEMPERATURE
FORECAST FOR TONIGHT GIVEN FREEZE HEADLINE CONCERNS.

WEDNESDAY...CLOUDS SHOULD PERSIST ACROSS MOST OF THE
CWA...ESPECIALLY FROM THE TRI CITIES AND POINTS OFF TO THE
SOUTHWEST. THIS WILL MAKE IT DIFFICULT TO WARM UP AND HIGHS COULD BE
STUCK IN THE UPPER 50S. SOUTHEAST WINDS WILL BE ON THE INCREASE
THROUGH THE DAY ON WEDNESDAY SO THERE WILL BE MORE OF A BREEZE
AROUND COMPARED WITH THE LIGHT WINDS WE EXPERIENCED TODAY.

.LONG TERM...00Z THURSDAY THROUGH TUESDAY.  PRIMARY CONCERN IN THE
EXTENDED CONTINUES TO BE THE TIMING OF PRECIPITATION CHANCES AS WE
WILL BE IN AN ACTIVE PERIOD...PATTERN-WISE.

BY 00Z THURS IT LOOKS LIKE THE UPPER LEVEL PATTERN WILL HAVE
PROGRESSED EASTWARD WITH THE RIDGE AXIS CURRENTLY OVER THE ROCKIES
PROGGED TO BE 500 MILES EAST AND OVER OUR CWA. AT THAT TIME THE
PATTERN OVER THE CONUS INDICATES TROUGHS ON THE EAST AND WEST COASTS
WITH RIDGING IN THE CENTRAL. BY SATURDAY MORNING THE RIDGE IS
FORECAST TO PROGRESS EAST SO THERE WOULD BE OVERALL RIDGING IN THE
EASTERN HALF OF THE CONUS WITH A LARGE BROAD TROUGH AND A COUPLE OF
CLOSED LOWS IN THE WESTERN HALF.  THIS WILL ALLOW SEVERAL SHORTWAVES
TO ROTATE THROUGH THE CENTRAL PLAINS FROM THURSDAY THROUGH NEXT
MONDAY BRINGING US OFF AND ON CHANCES FOR PRECIPITATION.  THE FIRST
OF THESE WAVES LOOKS LIKE IT WILL LIFT ACROSS THE REGION WED NIGHT
INTO THURSDAY. LOW LEVEL JET RAMPS UP AND SHOULD HELP TRANSPORT
HIGHER MOISTURE INTO THE AREA. INSTABILITY NOT THAT IMPRESSIVE AND
NEITHER ARE LOW/MID LEVEL LAPSE RATES SHOULD THREAT OF SEVERE
MINIMAL BUT WILL AT LEAST MENTION ISOLATED THUNDER. IN ADDITION TO
RAIN CHANCES...SOUTH WINDS SHOULD INCREASE THURSDAY AS THE PRESSURE
GRADIENT TIGHTENS UP ACROSS THE AREA WITH LEE TROUGH DEEPENING TO
OUR WEST.

MAY HAVE A REPEAT THURSDAY NIGHT WITH ANOTHER WAVE ROTATING THROUGH
AND WILL CONTINUE RAIN CHANCES. MODELS POINT TO AN INCREASE IN
SURFACE MOISTURE FROM THURS INTO FRIDAY WITH BETTER INSTABILITY
ESPECIALLY IN THE SOUTHWEST PART OF THE CWA. SURFACE FRONT SLATED TO
PUSH THROUGH THE AREA ON FRIDAY AND BY MAX HEATING TIME THE BEST
AREAS FOR THUNDERSTORMS SHOULD BE SOUTHEAST AND EAST OF OUR CWA IF
THE SPEED OF THE SYSTEM TURNS OUT AS EXPECTED. MAY NOT BE ABLE TO
PULL PRECIP CHANCES COMPLETELY BUT WILL WAIT FOR 12Z EC RUN AND
POSSIBLY 12Z GFS RUN...WHICH IS LATE...BEFORE DECIDING.

AS FAR AS THE REST OF THE PERIOD GO...FOLLOWED THE EC FOR THE MOST
PART. RAIN CHANCES TOUGH TO PIN DOWN EXACTLY SAT THROUGH MON BUT
APPEARS THAT AT LEAST SOME POSSIBILITY FOR RAIN EACH DAY AS WE STAY
IN CYCLONIC FLOW DURING THAT TIME WITH BIG UPPER WAVE EITHER STILL
JUST WEST OR OVER US.  ALSO WILL NEED TO CONTEND WITH STALLED
SURFACE BOUNDARIES IN THE AREA WHICH WILL ALSO BE THE FOCUS FOR
RAIN.  DID LEAVE OUT THUNDER MENTION AFTER SUNDAY AS BETTER
INSTABILITY REMAINS SOUTHEAST OF THE CWA SUNDAY NIGHT AND MONDAY.
ACTUALLY THE EARLY PART OF THE WORKWEEK COULD BE ON THE COOL SIDE
AND THE LATEST EC SHOWS THE RAIN/SNOW THICKNESS LINE NOT THAT FAR NW
OF OUR CWA BY 12Z MONDAY.  WENT AHEAD AND KEPT TUESDAY DRY AS IT
APPEARS THAT TROUGH AXIS SHOULD BE EAST OF CWA BY THEN.

.AVIATION...18Z KGRI TAF. VFR CONDITIONS WILL PREVAIL AT KGRI
THROUGH THE TAF VALID PERIOD. THE WIND WILL BE LIGHT AND OUT OF
THE EAST TODAY...BUT WILL SHIFT TO SOUTHEAST BY WEDNESDAY MORNING.
THERE COULD ALSO BE A SCATTERED TO BROKEN DECK OF MID CLOUDS
SITUATED BETWEEN 5000-7000 FT AGL THROUGH MUCH OF THIS PERIOD.
