.SYNOPSIS...

SHORT WAVE MOVING ACROSS THE CWA WITH A BAND OF ISOLATED RAIN
SHOWERS AND SPRINKLES THIS MORNING. HOWEVER...SINCE NOON A MORE
PERSISTENT BAND OF LIGHT SHOWERS HAD SET UP ROUGHLY ALONG THE I-80
CORRIDOR FROM ABOUT SCOTT COUNTY IA TO BUREAU COUNTY IL. HERE AT
THE WFO DVN WE PICKED UP .01 INCH OF RAIN. SUBSIDENCE IN THE WAKE
OF THE TROUGH HAS ENDED THE RAIN ELSEWHERE IN THE CWA AND THE SUN
WAS SHINING IN OUR WESTERN AND SW CWA...BUT MORE CLOUDS WERE
DROPPING SOUTHWARD INTO THE CWA. 3 PM TEMPERATURES RANGED FROM THE
UPPER 40S TO UPPER 50S.
WEAK LOW PRESSURE WAS OVER NORTHERN MO DRAGGING A COLD FRONT INTO

STRONGER SECONDARY COLD FRONT WAS PUSHING THROUGH THE DAKOTAS AND
NORTHERN MN WHERE CURRENT TEMPERATURES THERE WERE ONLY IN THE LOWER

&&
.SHORT TERM...(THIS EVENING THROUGH FRIDAY)
ISSUED AT 315 PM CDT THU OCT 30 2014
FORECAST FOCUS ON MUCH COLDER AND VERY WINDY THROUGH HALLOWEEN.
TONIGHT...A VERY STRONG COLD FRONT WILL SWEEP ACROSS THE CWA LATER
THIS EVENING AND OVERNIGHT. CLOUDS ALONG WITH A FEW SHOWERS SHOULD
ACCOMPANY THE FRONT WITH CLEARING...WINDY AND MUCH COLDER AIRMASS
THEN TO FOLLOW. MINIMUM TEMPERATURES WILL RANGE FROM THE MID 20S
AT INDEPENDENCE IA TO THE LOWER 30S IN OUR FAR SE COUNTIES. NORTH
WINDS WILL GUST TO AROUND 30 MPH ESPECIALLY AFTER MIDNIGHT AS THE
FRONT SWEEPS SOUTHWARD...AND STRONG COLD AIR ADVECTION ARRIVES. WE WILL
NEED TO TALK ABOUT COLD WIND CHILLS AS THEY DROP TO 10 TO 15 NW TO
THE LOWER 20S SE BY SUNRISE.
FRIDAY (HALLOWEEN)...THIS DAY WILL FEEL MORE LIKE WINTER WITH COLD
TEMPERATURES AND VERY WINDY CONDITIONS EVEN THOUGH THERE SHOULD BE
PLENTY OF SUNSHINE. A STRONG UPPER LEVEL TROUGH DIVING INTO THE
GREAT LAKES/OHIO VALLEY WILL SEND ARCTIC AIR PLUNGING INTO THE MIDWEST.
HIGH PRESSURE WILL BE PUSHING INTO THE UPPER MIDWEST SETTING UP A
TIGHT GRADIENT. NORTH WINDS WILL BE GUSTING TO NEAR 40 MPH WITH
STRONG COLD AIR ADVECTION. MAXIMUM TEMPERATURES WILL STRUGGLE TO
REACH THE UPPER 30S TO LOWER 40S...WHICH IS 15 TO 20 DEGREES BELOW
NORMAL FOR THE END OF OCTOBER. YOU WILL NEED TO REALLY BUNDLE UP
AS WIND CHILLS IN THE TEENS IN THE MORNING WILL ONLY RISE TO THE MID
20S TO LOWER 30S DURING THE AFTERNOON.
.LONG TERM...(FRIDAY NIGHT THROUGH THURSDAY)
ISSUED AT 315 PM CDT THU OCT 30 2014

FOR FRIDAY MID EVENING THROUGH SATURDAY MORNING. LOWS IN ALL
LOCATIONS SHOULD DIP TO THE LOWER TO MID 20S...WITH SOME UPPER TEENS
POSSIBLE IN THE WAPSIPINICON VALLEY LOCATIONS...AS WELL AS LOW LYING
AREAS. CLEAR SKIES AND LIGHT WINDS AFTER MIDNIGHT
SATURDAY...THE STRONG HIGH PRESSURE WILL BE OVERHEAD...WITH PLENTY
OF SUN. THE LIGHT WINDS AND VERY COLD AIR MASS WILL ONLY ALLOW FOR
HIGHS TO REACH THE LOWER TO MID 40S. EXPECT ANOTHER CHILLY NIGHT
WITH LIGHT EAST WINDS SATURDAY NIGHT...WHICH WILL FAVOR ROCK RIVER
VALLEY SITES INCLUDING MOLINE TO SEE THE COLDEST LOWS IN THE MID 20S
WHILE WESTERN SITES ONLY FALL TO THE UPPER 20S. SUNDAY WILL SEE THE
RIDGE SHIFT EAST...AS THE LARGE UPPER TROF TO IN THE WESTERN CONUS
BEGINS TO SHIFT EAST. A BROAD SOUTHERLY FLOW WILL SET UP WITH A
RATHER TIGHT PRESSURE GRADIENT OVER THE MIDWEST. SOUTH WINDS SUNDAY
SHOULD BE SUSTAINED AROUND 12 MPH EAST TO 18 MPH WEST...WITH GUST OF
20 TO 30 MPH DURING THE AFTERNOON. THOUGH TEMPERATURES SHOULD WARM
TO THE UPPER 40S TO LOWER 50S...WIND CHILLS WILL REMAIN MAINLY IN
THE LOWER TO MID 40S. IN OTHER WORDS...SATURDAYS COLD SUNSHINE MAY
BE THE MORE PLEASANT WEEKEND DAY.
MOISTURE WILL EVENTUALLY WORK UP THROUGH THIS DEEP FLOW...AS THE
SLOW MOVING TROF EMERGES INTO THE PLAINS MONDAY. WHILE MODELS ARE
DIFFERING ON THE SPEED OF THE FRONT WILL ARRIVES INTO IOWA
MONDAY...THEY ALL SHOW IT TO BE AN ACTIVE FRONT WITH WIDESPREAD
RAIN. THE CANADIAN IS MOST PHASED WITH A LOW MOVING ALONG THE FRONT
THROUGH TUESDAY...WHILE THE ECMWF IS LEAST PHASED AND MOST
PROGRESSIVE. THE GFS IS IN THE MIDDLE...AND MAY BE THE BEST FIT FOR
NOW FOR MONDAY THROUGH TUESDAY. RAIN CHANCES REMAIN CHANCE MONDAY
FOR NOW...AND ARE IN THE LIKELY RANGE MONDAY NIGHT...WHICH IS
CONTINUED NOW INTO TUESDAY EAST. AS THE SYSTEM PHASING IS MORE
CERTAIN...IT IS LIKELY THAT THESE POPS WILL NARROW INTO A MORE TIGHT
WINDOW OF TIME...BUT FOR NOW ARE OVER 3 PERIODS OF THE FORECAST.
BEHIND THE SYSTEM TUESDAY...EXPECT TEMPERATURES NEAR NORMAL IN ZONAL
FLOW WITH SYSTEM MAINLY PASSING ALONG THE CANADIAN BORDER.
