AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE OMAHA/VALLEY NE
257 AM CST SUN FEB 12 2006

.DISCUSSION...

WINDS TODAY AND TEMPERATURES INTO MIDWEEK ARE THE MAIN FORECAST
CONCERNS IN THE SHORTER TERM WITH POTENTIAL SNOW EVENT THEN THE
FOCUS IN THE EXTENDED.

SHORT TERM...TODAY AND TONIGHT.  WATER VAPOR IMAGERY SHOWED AN
EMBEDDED UPR TROF DROPPING SWD ACROSS THE ERN DKTS. WK WARM ADVCTN
AHEAD OF IT WAS SPREADING A BAND OF MID CLOUDS ACROSS THE CWA WITH
STRATO CU DVLPG AND SPREADING SWD ACROSS ND AND PARTS OF NRN SD. PER
MID LVL QG FORCING FM BOTH NAM AND GFS MOST OF THE LIFT ASSOCD WITH
THE AFOREMENTIONED TROF WAS THE WARM ADVCTN THIS MORNING. WITH A
DRY SUB-CLOUD LYR CURRENTLY IN PLACE....IT MAY BE HARD TO GENERATE
ANY FLURRIES UNTIL BLYR COOLS AND MOISTENS A LTL AS STRATO CU
MANAGES TO WORK INTO THE AREA. EVEN THEN IT APPEARS A LTL MARGINAL
AS DECK CURRENTLY NOT SOLID AND LIFT ABATES FAIRLY QUICKLY.
TRIMMED BACK FLURRY MENTION TO JUST NWRN ZONES WHERE SOME LIFT AND
LOW CLOUDS COULD COINCIDE FOR A BIT THIS MORNING. AT THE SFC A
WIND SHIFT/CDFNT WAS JUST SPREADING INTO THE FAR NWRN CWA AS OF
08Z. A WEDGE OF SLIGHTLY MILDER H85 AIR HAD WORKED JUST AHEAD OF
THE UPR SHORTWV TROF AND THIS WAS MIXING DOWN TO THE MID TO UPR
20S AT THE SFC AS THE WINDS SHIFT TO THE NW. HOWEVER...A LTL
FARTHER TO THE N COLDER TEENS WILL ATTEMPT TO OVER TAKE THIS
SLIGHTLY MILDER AIR AS IT CROSSES CWA. FELT IT WARRANTED THAT WITH
SOME SUNSHINE AND COLD ADVCTN NOT ARRIVING UNTIL LATER THIS
MORNING TO BUMP UP TEMPS A BIT OVER PARTS OF THE W AND S INTO
LOWER 30S. COLD ADVCTN THEN LATER THIS MORNING SHOULD ATTEMPT TO
MIX DOWN H85 WINDS. WITH MERRIMAN PROFILER ALREADY INDICATING 55 KTS
AT 850 MB...NAM/GFS FCST OF 35-45 KTS OVR WRN ZONES SEEMS REASONABLE.
THUS WL ISSUE A WIND ADVSRY WRN ZONES FOR MOST OF TDA. EVENING
LOWS WITH STEADY OR RISING TEMPS STILL LOOKS ON TRACK TNGT...SPCLY WRN
CWA...AS FLOW BACKS AHEAD SHORTWV RIDGING THAT IS STILL FORECAST
TO SPREAD SEWD OVER CNTRL PLAINS. LTL/NO CHANGES THERE.

DEEP MIXING LIKELY ON MONDAY AS SFC TROF SWINGS THROUGH AND WINDS
SHIFT BACK TO NW.  STILL A LITTLE CONCERNED THAT MINOR SNOW COVER
AND SLIGHT AFTN COOL ADVCTN COULD LIMIT FULL POTENTIAL NERN ZONES
AND TRIMMED BACK JUST A TOUCH THERE.  FOR TUE AND TUE NGT...00Z RUNS
NAM/GFS AND SOME EXTRAPOLATION OF THE ECMWF ALL POINT TO A FRONT
SETTLING S A LTL FASTER THAN PREV RUNS.  THUS KNOCKED SVRL DEGREES
OFF OF HIGHS TUESDAY ACROSS THE N AND LOWERED LOWS CNTRL AND S TUE
NGT AND HIGHS WED AS IT APPEARS FRONT SHOULD BE SOUTH OF THE
FORECAST AREA BY TUE NGT.

ARCTIC AIRMASS MOVING SWD INTO THE NRN PLAINS BY LATE NEXT WEEK IS
STILL FORECAST TO BE QUITE A BIT COLDER THAN THE CURRENT ONE...SOME
15-20 DEGREES AT 850 MB USING A GFS/ECMWF BLEND. HOWEVER...STILL
MANY QUESTIONS TO HOW QUICKLY OR HOW MUCH OF THIS COLD AIR SETTLES
OVER THE CWA AND TIMING OF ANY WAVES THAT WILL BE EJECTING OUT OF
THE LARGER SCALE UPR TROF THAT WL EXTEND FROM A POLAR VORTEX SWWD
TO A POSITIVELY TILTED TROF OFF THE W COAST. THUS WILL GENERALLY
NOT MAKE ANY PCPN CHANGES TO EXTENDED PART OF THE FORECAST OTHER
THAN TO INCREASE POPS SLIGHTLY IN THE WED NGT/THU PD. THERE IS
SOME CONSENSUS BTWN GFS/ECMWF AND EVEN CMC OF A WAVE POSSIBLY
CAUSING SOME SFC CYCLOGENESIS OR INVERTED TROF MOVING ACROSS THE
PLAINS DURING THAT PD.
