WEATHER SUMMARY FOR IOWA
NATIONAL WEATHER SERVICE DES MOINES IA
811 PM CDT SUN APR 13 2014

WITH A HIGH TEMPERATURE OF 86 DEGREES ON SATURDAY...DES MOINES
WAS 1 DEGREE SHY OF SETTING A DAILY RECORD HIGH TEMPERATURE. 24
HOURS LATER...DES MOINES DID SET A RECORD...BUT NOT ONE RELATED TO
TEMPERATURES. WITH 1.51 INCHES OF PRECIPITATION AS OF 7 PM
SUNDAY...DES MOINES ALMOST DOUBLED THE PREVIOUS DAILY
PRECIPITATION RECORD OF 0.80 INCHES. TEMPERATURES WERE ALSO 40
DEGREES COOLER ON SUNDAY AT 4 PM THAN THEY WERE ON SATURDAY AT 4
PM. ACROSS THE REST OF THE REGION...FROM CENTRAL IOWA INTO WESTERN
WISCONSIN AND DOWN TO ILLINOIS...IT RAINED ALMOST NON STOP FOR ALL
OF SUNDAY. AS OF 7 PM...WATERLOO HAD 1.56 INCHES OF RAIN FOR
SUNDAY...GIVING THEM 3.52 INCHES OF RAIN SINCE SATURDAY AFTERNOON.
MARSHALLTOWN HAD 1.68 INCHES...GIVING THEM A 24 HOUR TOTAL OF 3.89
INCHES...AND THE NATIONAL WEATHER SERVICE IN JOHNSTON MEASURED
1.91 INCHES OF RAIN...GIVING THEM A 24 HOUR TOTAL OF 2.08 INCHES
OF RAIN. HIGH TEMPERATURES WERE GENERALLY SET SHORTLY AFTER
MIDNIGHT SUNDAY MORNING...AND VALUES DROPPED DOWN TO THE LOW TO
MID 40S BY THE AFTERNOON. BY 7 PM...TEMPERATURES IN NORTHWESTERN
IOWA AND SOUTHWESTERN MINNESOTA HAD FALLEN TO THE LOW 30S...WHICH
TRANSITION THEIR PRECIPITATION FROM RAIN TO SNOW. SUNDAY
AFTERNOON WINDS WERE ON THE BREEZY SIDE...BLOWING FROM THE NORTH
AT 20 TO 30 MPH...WITH SOME GUSTS APPROACHING 40 MPH.

EXPECTED THE TRANSITION SNOW FROM RAIN TO SNOW TO CONTINUE TO
CREEP SOUTHWARD INTO MONDAY MORNING. THE COLD TEMPERATURES
RESPONSIBLE FOR THIS TRANSITION ZONE WILL MAKE IT ALL THE WAY
THROUGH IOWA BY MONDAY MORNING. AIR TEMPERATURES WILL BE IN THE
MID 20S TO MID 30S ACROSS IOWA AND WIND SPEEDS WILL BE FROM THE
NORTH AT AROUND 25 TO 35 MPH. THIS WILL DROP WIND CHILL VALUES
DOWN TO THE SINGLE DIGITS IN NORTHWESTERN IOWA AND THE MID TO
UPPER TEENS ACROSS CENTRAL TO SOUTHERN IOWA. BY THE TIME THE VERY
COLD TEMPERATURES MAKE IT INTO THE DES MOINES METRO...MUCH OF THIS
PRECIPITATION SHOULD BE TO THE EAST...MEANING THERE SHOULD BE
LITTLE TO NO SNOWFALL. MONDAY AFTERNOON TEMPERATURES WILL BE IN
THE UPPER 30S TO LOW 40S ACROSS THE REGION SO ANY SNOW THAT DOES
FALL SHOULD MELT FAIRLY QUICKLY. SNOW TOTALS ARE EXPECTED TO REACH
1 TO 2 INCHES IN NORTHWESTERN IOWA...WITH A FEW POCKETS OF 3 INCH
ACCUMULATIONS. WITH THE AFOREMENTIONED STRONG WINDS...VISIBILITIES
COULD BE REDUCED TO LESS THAN ONE MILE ALONG WITH ROADWAYS
BECOMING SLIPPERY DURING PERIODS OF SNOW.

THE REST OF THIS WEEK LOOKS TO FEATURE NEAR TO BELOW NORMAL
TEMPERATURES WITH TUESDAY MORNING LIKELY FEATURING LOWS IN THE
20S. AFTER MONDAY...THE NEXT BEST CHANCE FOR PRECIPITATION WILL
BE WEDNESDAY INTO FRIDAY.
