WEATHER SUMMARY FOR IOWA
NATIONAL WEATHER SERVICE DES MOINES IA
803 AM CST WED JAN 21 2015

CLOUDY SKIES WERE COMMON ACROSS IOWA WITH PERIODS OF LIGHT SNOW
ACROSS THE NORTH AND EAST. FURTHER SOUTH PRECIPITATION WAS
ISOLATED AND MORE OF A RAIN AND SNOW MIX. TEMPERATURES AT 5 AM
RANGED FROM THE UPPER 20S TO LOWER 30S ACROSS THE NORTH TO THE MID
30S ACROSS THE FAR SOUTH. A WEST TO NORTHWEST WIND AT 10 TO 20 MPH
WAS COMMON OVERNIGHT.

THE UPPER MIDWEST WILL REMAIN IN AN ACTIVE FLOW WHERE UPPER LEVEL
DISTURBANCES RIDE THROUGH THE REGION.  MOISTURE IS LACKING FOR THE
MOST PART SO THE MAIN IMPACT WILL BE CLOUD COVER WITH PERIODIC
CHANCES MAINLY ACROSS FAR NORTHERN LOCATIONS.  TEMPERATURES WILL BE
ON THE COOL SIDE TODAY AND THURSDAY BUT WILL WARM FOR THE END OF THE
WEEK INTO THE WEEKEND.  BY FRIDAY HIGHS WILL BE IN THE 40S AND 50S.
A MORE POTENT UPPER LEVEL SYSTEM IS STILL EXPECTED TO PASS THROUGH
THE UPPER MIDWEST SATURDAY NIGHT THROUGH SUNDAY.  THE TRACK OF THE
SURFACE LOW THAT WILL DEVELOP IS NOW LOOKING TO BE A LITTLE FURTHER
NORTH.  THE RESULT WILL BE A SHIFT IN WHERE THE BEST CHANCES FOR
SNOW WILL OCCUR.  IT NOW APPEARS THAT SOUTHERN IOWA AND LOCATIONS
SOUTH WILL SEE RAIN OR A RAIN/SNOW MIX AT NIGHT WHILE NORTHERN IOWA
AND LOCATIONS NORTH WILL SEE CHANCES FOR SNOW.  GIVEN THE
UNCERTAINTY OF THE STORM TRACK AND JUST HOW MUCH WARM AIR WILL WORK
INTO THE REGION IT IS DIFFICULT TO SAY AT THIS POINT WHERE THE BEST
LOCATIONS WILL BE TO SEE SNOW BUT THIS SYSTEM DOES NOT LOOK LIKE IT
WILL BE A BIG SNOW PRODUCER AND THE SNOW COULD BE WET AND SLUSHY IF
TEMPERATURES ARE IN THE LOWER TO MID 30S WHICH APPEARS LIKELY.
