AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE OMAHA/VALLEY NE
155 AM CST SAT DEC 11 2004

.DISCUSSION...
MAIN CONCERNS IN THE SHORT TERM ARE CLOUD COVER AND MAXIMUM TEMPS 
FOR TODAY. WATER VAPOR SATELLITE IMAGERY LOOP SHOWED A LARGE MID
TROPOSPHERIC RIDGE OVER THE WESTERN THIRD OF THE NATION...A FAIRLY 
DEEP TROUGH OVER THE EASTERN U.S. AND A CLOSED LOW OVER THE GREAT 
LAKES. A RIDGE OF HIGH PRESSURE AT THE SURFACE STRETCHED FROM 
WESTERN KANSAS ACROSS NEBRASKA AND INTO WESTERN MINNESOTA. CURRENT 
LOW CLOUDINESS SHOULD CONTINUE TO DECREASE FROM WEST TO EAST...AS 
SURFACE RIDGE MOVES EASTWARD. WARM FRONT EXTENDED FROM EASTERN 
MONTANA INTO WESTERN NEBRASKA EARLY THIS MORNING...AND WILL MOVE 
EASTWARD/NORTHEASTWARD TODAY. ISENTROPIC FORECAST CHARTS INDICATE 
BEST BET FOR ANY PRECIPITATION TODAY IS OVER MINNESOTA...WHERE LIFT 
WILL BE ABLE TO CAUSE SATURATION IN THE LOWER AND MID LEVELS. IN 
OUR LOCAL AREA...TEMPERATURES TODAY WILL BE WARMER THAN YESTERDAY. 
EXPECT HIGHS TO REACH AROUND 50 OR A LITTLE MORE ALONG AND WEST OF
A LINE FROM NORFOLK TO LINCOLN...BUT ONLY MID AND UPPER 40S EAST OF 
THAT LINE. STILL NOT BAD...CONSIDERING THAT OUR NORMAL HIGHS FOR 
MID DECEMBER ARE IN THE MID 30S.

AS A SURFACE LOW MOVE EASTWARD ACROSS SOUTHERN CANADA LATE TODAY 
AND TONIGHT...A COLD FRONT WILL DROP SOUTHWARD ACROSS THE NORTHERN 
AND CENTRAL PLAINS. STRONG/GUSTY NORTHWEST WINDS BEHIND THE FRONT 
WILL BRING COOLER AIR BACK INTO THE AREA. MIGHT NEED TO ISSUE A 
WIND ADVISORY FOR SUNDAY...BUT NO HIGHLIGHTS FOR NOW.  THERE DOES 
NOT SEEM TO BE MUCH IN THE WAY OF LOW LEVEL MOISTURE WITH THE 
FRONT...SO WILL NOT MENTION ANY PRECIPITATION WITH FRONTAL PASSAGE.

NO SIGNIFICANT PRECIPITATION IS EXPECTED WITH THE BALANCE OF THE 
7 DAY FORECAST. COLD AIR WILL CONTINUE TO MOVE IN THROUGH SUNDAY 
NIGHT AS HIGH PRESSURE BUILDS SOUTHEAST FROM MONTANA. HIGHS MONDAY 
SHOULD ONLY BE IN THE 30S. TEMPERATURES ARE EXPECTED TO MODERATE 
A LITTLE ON TUESDAY AND WEDNESDAY AS THE HIGH MOVES OFF TO THE 
SOUTHEAST... AND WINDS SHIFT TO THE SOUTH OR SOUTHWEST. IT APPEARS 
THAT ANOTHER FRONT WILL PUSH INTO THE AREA FROM THE NORTHWEST 
WEDNESDAY NIGHT. HOWEVER...THE MAJORITY OF THE COLD AIR WITH THIS 
FRONT SHOULD STAY TO OUR NORTHEAST. FLURRIES COULD OCCUR BEHIND 
THE FRONT LATE WEDNESDAY NIGHT INTO THURSDAY MORNING...BUT CHANCES
ARE HIGHER TO OUR NORTH AND EAST.
