AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE OMAHA/VALLEY NE
900 PM CST THU MAR 1 2007

.UPDATE...

UPDATED HEADLINES DUE TO SNOW ENDING MORE QUICKLY THIS EVENING.
GRIDS AND TEXT PRODUCTS HAVE BEEN SENT.

&&

.DISCUSSION...
SNOW WAS DWINDLING OVER WESTERN IOWA COUNTIES...WITH ONLY EASTERN
SECTIONS OF MONONA AND SHELBY COUNTIES SEEING FALLING SNOW. ALL
AREAS STILL HAD WINDS GUSTING TO OR ABOVE 35 MPH. SO HAVE KEPT
BLIZZARD WARNING GOING FOR THOSE TWO COUNTIES WHERE REDUCED
VISIBILITIES IN FALLING AND BLOWING SNOW WILL OCCUR. AREA
OBSERVATIONS INDICATE BLOWING SNOW IS NOT MUCH OF A
PROBLEM...HOWEVER BETWEEN OB SITES EXPECT BLOWING OR DRIFTING SNOW
TO STILL CAUSE TRAVEL PROBLEMS. WHEN WIND DIMINISHES SOMEWHAT
THROUGH THE REST OF THE EVENING...THESE TRAVEL PROBLEMS SHOULD
SUBSIDE.

A QUICK LOOK AT THE JUST-ARRIVING 00Z NAM SHOWS UPPER TROUGH
WRAPPING BACK WEST MAY TRIGGER SOME MORE LIGHT SNOW IN NORTHEAST
NEBRASKA BY MORNING. CURRENT GRIDS HAVE THIS TREND SO ONLY MINOR
ADJUSTMENTS WERE MADE THERE.

&&

.PREV DISCUSSION... /ISSUED 346 PM CST THU MAR 1 2007/

SHORT TERM...TONIGHT THROUGH SUNDAY.
CONTINUING BLIZZARD CONDITIONS TONIGHT...THEN POTENTIAL SNOW AND
BLOWING SNOW ADVISORY FRIDAY AND FRIDAY NIGHT...ARE THE PRIMARY
FORECAST CONCERNS.

STRONG LOW PRESSURE SYSTEM CONTINUES TO STRENGTHEN AS IT MOVES
INTO EAST CENTRAL IOWA. MOST OF THE SNOW HAS PUSHED EAST OF THE
MISSOURI RIVER THIS AFTERNOON AS DEFORMATION BAND SNOWS CONTINUED
ACROSS WESTERN IOWA STRETCHING NORTH INTO MINNESOTA. ONE INTENSE
BAND WITHIN THE DEFORMATION ZONE HAS SET UP FROM MONONA COUNTY
INTO POTTAWATTAMIE COUNTY...LIKELY DROPPING AT LEAST AN INCH AN
HOUR SNOWS THERE. SOME SLIGHT WESTWARD DRIFT TO THE SNOW WAS ALSO
NOTED ON RADAR LOOPS FROM NEAR TEKAMAH TO OMAHA. WINDS ARE NOT AS
STRONG AS EARLIER...BUT 30 TO 40 MPH WINDS WERE STILL WIDESPREAD
ACROSS MOST OF THE CWA. SO FOR THE SHORT TERM...WILL MAINTAIN
BLIZZARD WARNINGS WHERE SNOW IS STILL FALLING...AND BLOWING SNOW
ADVISORIES JUST WEST AND SOUTH OF THE OMAHA METRO.

SNOWFALL HAS BEEN QUITE HEAVY ACROSS EASTERN NEBRASKA AND WESTERN
IOWA. LATEST REPORT RANGE FROM 6 TO 10 INCHES SOUTH AND SOUTHWEST
OF OMAHA AS WELL AS FAR SOUTHWEST IOWA. THE OMAHA METRO HAD
AMOUNTS FROM ABOUT 7 TO 14 INCHES...WITH THE HIGHER TOTALS FALLING
OVER WESTERN SECTIONS OF DOUGLAS AND SARPY COUNTIES WHERE AN
INTENSE BAND HAD SET UP EARLIER IN THE DAY. AMOUNTS WERE EVEN
HIGHER NORTHEAST OF THE METRO...WITH ONE REPORT OF 16 INCHES THUS
FAR IN HARLAN IOWA. GIVEN THE CONTINUED DEVELOPMENT FROM
POTTAWATTAMIE COUNTY NORTH...EXPECT ANOTHER 1 TO 3 INCHES THERE
THIS EVENING.

ALSO EXPECT THE SNOW TO SLOWLY WANE IN FAR EAST CENTRAL NEBRASKA
THIS EVENING...SO AM GOING TO ALLOW BLIZZARD WARNING TO EXPIRE AT
6 PM FOR THE METRO AREA...BUT HOLD ONTO IT FOR WESTERN IOWA WHERE
AT LEAST LIGHT SNOW IS LIKELY OVERNIGHT.

MAIN LOW PRESSURE SYSTEM IS FORECAST TO LIFT NORTHEAST INTO
WISCONSIN LATER TONIGHT THEN STALL. MEANWHILE A LOBE OF VORTICITY
WILL ROTATE BACK WEST...PROVIDING ANOTHER CHANCE FOR SNOW DURING
THE DAY FRIDAY AND FRIDAY NIGHT. LAYER Q-VECTOR CONVERGENCE WILL
OVERSPREAD NORTHERN NEBRASKA FRIDAY ALONG WITH DECENT
FRONTOGENESIS IN THE 600-650MB LAYER. SPECIFIC HUMIDITIES OF 1 TO
2 G/KG SUGGEST ANOTHER INCH OR TWO OF SNOW IS POSSIBLE FOR MOST OF
THE NORTHERN CWA...BUT A MORE PROLONGED PERIOD OF LIGHT SNOW COULD
ADD UP TO NEAR 4 INCHES IN FAR NORTHEAST NEBRASKA. WINDS WILL
CONTINUE TO BE A PROBLEM...AVERAGING 20 TO 30 MPH...SO SNOW OR
BLOWING SNOW ADVISORIES MAY BE NEEDED FOR PARTS OF NORTHEAST
NEBRASKA FRIDAY AND/OR FRIDAY NIGHT. WILL DEAL WITH THOSE
HEADLINES ON THE OVERNIGHT SHIFT.

THE REST OF THE WEEKEND WILL BE MORE TRANQUIL. UPPER LOBE WILL
ROTATE SOUTHEAST OF THE AREA LEAVING MOSTLY CLEAR SKIES IN ITS
WAKE. SURFACE HIGH PRESSURE WILL SLIDE INTO THEN SOUTH OF NEBRASKA
SATURDAY INTO SUNDAY. GUSTY NORTHWEST WINDS SATURDAY WILL KEEP
TEMPERATURES COOL IN THE 30S...BUT WARM ADVECTION SUNDAY WILL PUSH
HIGHS TOWARD 40 IN AREAS WITH MINIMAL SNOW COVER OUT WEST.

LONG TERM...SUNDAY NIGHT THROUGH THURSDAY.
PERIOD WL EXPERIENCE AN UPPER LEVEL PATTERN CHANGE THROUGH THE
EXTENDED. UPPR LVL RIDGING OVR THE WRN US WL START TO EXPAND EWD
INTO THE CNTRAL PLAINS. GLOBAL MODELS ARE GENERALLY IN AGREEMENT
WITH THIS PATTERN...BUT DIFFER MAINLY WITH THE STRENGTH OF A
SHORTWAVE TO TOP THE WRN US RIDGE ON MON AND HOW MUCH COOLING
INFLUENCE THAT WILL HAVE FOR THE CWA ON TUES/WED. GFS CONTS TO INDC
A COOLER PATTERN THAN THE EC. PREFER A BLENDED APPROACHED AT THIS
TIME...WHICH ALLOWS FOR A FRONT TO DROP INTO THE AREA MONDAY
NIGHT...BUT NOT HAVE THE DEGREE OF COOLING INDICATED BY THE GFS. SFC
FNT LIKELY TO LIFT/DEVELOP NORTH BY THURS WITH ABOVE NORMAL TMPS
RETURNING. HAVE INDICATED THAT IN THE FORECAST FOR THURS...BUT
REMAIN BELOW OPERATIONAL MEX GUIDANCE. THE PERIOD SHOULD ALSO REMAIN
DRY WITH GENERAL ZONAL OR NW FLOW ACRS THE FA.
