4 FEB 2011 EXTENDED FORECAST

HIGH PRESSURE WILL REMAIN OVER IOWA TODAY BEFORE THE FIRST OF A SERIES OF WEAK WEATHER SYSTEMS MOVES THROUGH IOWA TONITE.

WARMER AIR WILL SPREAD INTO THE WEEKEND AS HIGH TEMPS REACH NEAR 30 SATURDAY AND SUNDAY.

ALONG WITH THE WARMER TEMPERATURES WILL BE SOME LT SNOW BEGINNING FRIDAY NIGHT AND CONTINUING INTO MONDAY.  WE'LL SEE A SERIES OF WEAK SYSTEMS MOVING THRU THE AREA - TIMING OF EXACTLY WHEN THE SNOWS WILL OCCUR IS TUFF AT BEST - SO HAVE OPTED WITH SNOWSHOWERS WITH ACCUMULATIONS OF 1-3 INCHES THRUOUT CENTRAL IOWA FROM EARLY SATURDAY THRU MONDAY - WITH THE BRUNT OF THE SNOWFALL COMING SUNDAY AND EARLY MON WITH QUICK SHOTS OF MODERATE SNOWFALL PRIOR TO COLD FRONAL PASSAGE.  EXPECT UP TO 1-2 INCHES IN POW CTY, WHILE JUST TO OUR NORTHEAST CAN EXPECT UP TO 3 INCHES BY NOON MONDAY.

A STRONG COLD FRONT WILL MOVE INTO IOWA MONDAY ENDING THE CHANCES FOR SNOW - BUT WILL ALSO USHER IN SHARPLY COLDER AIR ONCE AGAIN.....

HEADS-UP:  THE NEXT SHOT AT SNOW WILL COME ON WED.  THE FORECAST MODELS ARE TRYING TO INDICATE A SYSTEM DEVELOPING TO OUR SOUTHWEST AND MERGING WITH THE COLDER AIR THAT SINKS IN MON/TUE.  RIGHT NOW IT'S LOOKING LIKE THEY WILL MERGE - WITH THE HEAVIEST SNOWFALL TO OUR SOUTH.  HOWEVER, LIKE THE STORM THIS WEEK, 50 MILES IN ANY DEVIATION OF THE STORMTRACK WILL MAKE A WORLD OF DIFFERENCE IN SNOW LOCATION AND SNOWFALL TOTALS.  SOMETHING TO WATCH.


Today thru Sun 4th thru 6th - Dry Today - then Mostly Cloudy with Flurries Thru Sat - changing to Lt Snow Late Sat into Sunday (1-2 Inches) - Highs Mid to High 20's.

Mon/Tues 7th/8th - Flurries/Windy Mon (1 Inches) - then Dry/Breezy - Highs 15 decreasing to 5 Tues Lows -5 to -10.

Wed thru Fri 9th thru 11th - Snow/Breezy Wed - Dry Thurs/Fri - Highs 12 Wed to 5 Thurs - Lows near -5.

After the 11th?  Looking at a period of unsettled weather for a week or so as numurous Artic Cold pushes coupled with brief warmups brings weather thru the Central Plains. We should see some snow mixed with rain thru the 15th - and possibly ending the period out with some icy conditions turning to snow.
