WEATHER SUMMARY FOR IOWA
NATIONAL WEATHER SERVICE DES MOINES IA
550 AM CST SAT DEC 27 2014

A VERY MESSY WEATHER SYSTEM WAS SHIFTING ACROSS IOWA OVERNIGHT.  THE
PRECIPITATION THIS SYSTEM BROUGHT WITH IT RANGED FROM FREEZING
DRIZZLE TO SNOW NORTHWEST OF A LINE FROM MASON CITY TO DES MOINES TO
A WINTERY MIX SOUTHEAST OF MASON CITY TO NEWTON TO DRIZZLE AND RAIN
SOUTHEAST OF A LINE FROM WATERLOO TO CENTERVILLE.  MOST OF THE
PRECIPITATION HAS ENDED ALTHOUGH AREAS OF LIGHT SNOW AND PATCHY
FREEZING DRIZZLE ACROSS THE NORTH HAS PROMPTED THE CONTINUANCE OF
THE WINTER WEATHER ADVISORY UNTIL AT LEAST EARLY MORNING.  AT 5 AM
TEMPERATURES RANGED FROM THE MID TO UPPER 20S NORTH AND WEST TO THE
MID TO UPPER 30S FAR SOUTHEAST.  WINDS WERE SWITCHING ACROSS THE
STATE FROM A WESTERLY DIRECTION TO A MORE NORTHERLY DIRECTION AT 10
TO 20 MPH.

AS THIS WEATHER SYSTEM PULLS EAST TODAY CLOUDS WILL LIKELY LINGER
UNTIL AT LEAST LATE AFTERNOON BUT A MORE ZONAL FLOW ALOFT WILL KEEP
TEMPERATURES SEASONAL THROUGH MONDAY.  ON MONDAY A LARGE LOW
PRESSURE SYSTEM WILL DEVELOP OVER THE SOUTHWEST UNITED STATES.  IT
NOW APPEARS THAT THIS LOW WILL DIG INTO THE SOUTHWEST THEN
EVENTUALLY MOVE ACROSS THE SOUTHERN PLAINS.  PRECIPITATION WITH THIS
SYSTEM WILL FOR THE MOST PART MISS IOWA THOUGH LIGHT SNOW MAY GRAZE
NORTHERN INTO CENTRAL IOWA ON MONDAY.  AS THIS SYSTEM PASSES IT WILL
ALLOW COLD AIR TO ONCE AGAIN POUR INTO THE UPPER MIDWEST.  HIGHS FOR
TUESDAY WILL RANGE FROM THE SINGLE DIGITS NORTH TO TEENS SOUTH.
SOME MODERATION IN TEMPERATURE WILL OCCUR BY NEW YEARS DAY WITH
SEASONAL HIGHS BY NEXT SATURDAY.  HOWEVER THIS WILL BE SHORT LIVED
BECAUSE ANOTHER WEATHER SYSTEM OVER CANADA WILL BUCKLE THE FLOW OVER
THE REGION BRINING A NORTHWEST FLOW AND COLDER AIR BACK INTO THE
UPPER MIDWEST BY LATE NEXT WEEKEND.  THERE DOES NOT APPEAR TO BE
ANY BIG WEATHER SYSTEMS ON THE HORIZON FOR THE UPPER MIDWEST SO
OTHER THAN BOUTS OF COLD TEMPERATURES...WE SHOULD NOT SEE MUCH IN
THE WAY OF SNOWFALL.
