AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE OMAHA/VALLEY NE
326 AM CST MON FEB 28 2011
.DISCUSSION...
TEMPERATURES THROUGH THE WEEK...AND A SMALL CHANCE FOR PRECIPITATION
AT MID WEEK...ARE THE PRIMARY FORECAST CONCERNS.
LOW PRESSURE SYSTEM THAT BROUGHT LIGHT PRECIP TO OUR SOUTHEAST IN
THE AFTERNOON AND EVENING...AND SPARKED STRONG STORMS IN KANSAS AND
MISSOURI...WAS MOVING QUICKLY EAST THIS MORNING. SKIES HAVE CLEARED
IN OUR CWA BEHIND THIS SYSTEM AS SURFACE HIGH PRESSURE SETTLES INTO
THE REGION. TEMPERATURES WILL LIKELY DROP INTO THE SINGLE DIGITS
THIS MORNING IN NORTHEAST NEBRASKA...WITH TEENS OVER THE REST OF THE
CWA. THIS COLD START MAY LIMIT HIGHS A BIT MORE THAN PREVIOUS
FORECASTS...AND NEW MODELS CONCUR. WITH SUNSHINE AND A RETURN TO
SOUTHERLY FLOW THIS AFTERNOON...STILL THINK HIGHS IN THE MID TO
UPPER 30S ARE LIKELY...WITH SOME 40S IN OUR WEST AND SOUTHWEST.
SOUTH WINDS TONIGHT THEN SOUTHWEST FLOW TUESDAY SHOULD KEEP LOWS IN
THE 20S TONIGHT...WITH HIGHS TUESDAY APPROACHING 50. HOWEVER A MID
LEVEL SHORTWAVE MOVING THROUGH THE NORTHERN PLAINS WILL PUSH A COLD
FRONT INTO NORTHERN NEBRASKA TUESDAY MORNING...THEN TO THE SOUTH OF
OUR AREA BY THE EVENING. COOL ADVECTION IN THE NORTH WILL LIMIT
HIGHS TO THE MID 40S THERE.
COLD ADVECTION CONTINUES TUESDAY NIGHT AND WILL PUSH LOWS BACK INTO
THE TEENS TO LOWER 20S. SUNSHINE ON WEDNESDAY WILL BE OFFSET BY
COOLER EAST OR SOUTHEAST LOW LEVEL WINDS...SO HIGHS IN THE 30S
SHOULD BE ALL WE CAN MUSTER. WINDS BECOME SOUTHERLY WEDNESDAY NIGHT
AS ANOTHER WAVE ROLLS THROUGH THE NORTHERN PLAINS...INDUCING SURFACE
LOW PRESSURE IN THE NORTHERN HIGH PLAINS. THAT WAVE AND ASSOCIATED
COLD FRONT IS FORECAST TO PUSH THROUGH THE CWA ON THURSDAY...WITH
DECENT WARM ADVECTION AHEAD OF IT. CLOUDS WILL CERTAINLY BE ON THE
INCREASE WEDNESDAY NIGHT AND THURSDAY...AND MOISTURE PROFILES
SUGGEST PRECIP IS POSSIBLE...ESPECIALLY IN OUR NORTH ON THURSDAY.
TEMPERATURES SHOULD SUPPORT ALL LIQUID DURING THE DAY THURSDAY...SO
WILL MAINTAIN RAIN CHANCES THEN. AND DESPITE MORE CLOUD COVER...
EXPECT HIGHS AGAIN CLOSE TO 50 IN THE SOUTHERN CWA.
COOLER TEMPS ARE EXPECTED FRIDAY INTO SATURDAY BEHIND THURSDAY
FRONTAL SYSTEM. WILL ALSO MAINTAIN SMALL RAIN THEN RAIN OR SNOW
CHANCES IN THE SOUTH FRIDAY INTO FRIDAY NIGHT AS ANOTHER MID LEVEL
TROUGH SWINGS THROUGH THE PLAINS JUST TO THE SOUTH OF OUR CWA. THEN
NO CHANGES TO THE WEEKEND FORECAST AT THIS TIME...WITH DRY
CONDITIONS AND HIGHS NEAR 40.
