What happened

The episode as NWS DMX wrote it up.

Low pressure intensified as it moved across Iowa during the evening of the 31st into the morning of the 1st. A strong cold front passed through the state with a very tight pressure gradient behind the low. Strong winds became established in the low levels with winds below 5000 feet AGL in the 40 to 60 kt range. Strong subsidence behind the front allowed the strong winds aloft to mix down. A widespread area of north central into central Iowa reported sustained winds of 40 to 45 MPH with spotty gusts near 60 MPH recorded over the north during the predawn hours. The strongest winds occurred on the bridge over Saylorville Lake in Polk County with a wind gust of 72 MPH. Winds of 59 MPH were reported in Hancock County at Kanawha and in Marshall County at Marshalltown. Some tree damage occurred, along with minor property damage. Spotty power outages were reported around the state as well. There were about 1000 customers out of power in the Des Moines Metro area before dawn on the 1st, with nearly 2500 out of power in the Waterloo Metro area. The winds dropped off toward sunrise, allowing many of the customers out of power to be placed back on line. A shortwave dropped southeast across the area during the day on the 1st, bring another round of high winds. Though winds did not gust to 50 kts with the second round, most locations reported sustained winds of 40 to 45 MPH with gusts to around 55 MPH for several hours through the mid morning and early afternoon. Additional power outages occurred with around 2000 more homes knocked out in the Des Moines Metropolitan area. Overall, damage was limited with the event due to a couple of factors. One was the fact that the event was a low end high wind event, the second being it was January, the tree damage is limited due to the lack of leaves.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DES MOINES IA
535 PM CST SAT DEC 31 2011

...UPDATED FOR 06Z TAF/S AND SHORT TERM...

.SHORT TERM /TONIGHT/...

05Z UPDATE...SNOW BAND OVER NORTHERN IOWA LIFTING INTO MINNESOTA BY
05Z.  SECOND AREA OF RAIN/SNOW OVER SOUTH CENTRAL IA. THIS AREA
SHOULD MOVE OUT OF SOUTH CENTRAL IOWA AFTER MIDNIGHT.  SURFACE WINDS
CONTINUED TO SLOWLY INCREASE THIS EVENING.  AS SURFACE LOW MOVES
NORTHEAST AND DEEPENS AND AS FLOW ALOFT INCREASES ALONG WITH STRONG
SUBSIDENCE...EXPECT WINDS TO CONTINUE TO INCREASE AFTER MIDNIGHT.
WITH MAIN PRECIPITATION ENDING NORTH CENTRAL AND LACK OF SIGNIFICANT
VISIBILITY RESTRICTIONS...WILL CANCEL WINTER WEATHER ADVISORY BY
06Z.

PREVIOUS DISCUSSION...DYNAMIC SYSTEM CRANKING UP AND ENTERING SW IA
CURRENTLY. WIND GUSTS IN EXCESS OF 60 MPH HAVE BEEN COMMON FROM SE
WYOMING...COLORADO AND WESTERN KANSAS AND NEBRASKA. 850 MB
SUBSIDENCE ASSOCIATED WITH THESE GUSTS WILL BE DEFLECTED A BIT TO
THE SOUTH OF IOWA OVERNIGHT THROUGH KS AND MO. HOWEVER ANOTHER SHORT
WAVE AND ASSOCIATED GOOD SUBSIDENCE IN ITS WAKE WILL ARRIVE AFTER
MIDNIGHT TONIGHT. LOW PRESSURE WILL MOVE FROM SOUTH CENTRAL IOWA
INTO SOUTHERN LAKE MICHIGAN OVERNIGHT. A COLD FRONT WILL SWEEP
ACROSS THE STATE IN THE WAKE OF THE LOW BRINGING STRONG COLD
ADVECTION AND VERY STRONG NORTHWEST WINDS. MIXED LAYER WINDS OF 50
TO 55 KTS OVER THE ENTIRE AREA. MOMENTUM TRANSFER OF THESE WINDS
WILL BE FAIRLY EFFICIENT DUE TO THE COLD ADVECTION AND
AFOREMENTIONED 850 MB SUBSIDENCE AND THUS A STRONG POSSIBILITY OF
MEETING HIGH WIND CRITERIA. IN ADDITION...A STRONG PRESSURE GRADIENT
IN EXCESS OF 50 UBARS/KM AND STRONG PRESSURE RISES OVER 14 MB/6HRS
WILL FURTHER ENHANCE WINDS OVERNIGHT. LIKELY TO BE TWO PEAK TIMES
FOR THE STRONGEST WINDS. THE FIRST WITH THE FRONTAL PASSAGE AND THE
NEXT INTO SUNDAY.

PRECIPITATION WILL BEGIN AS RAIN THIS EVENING THEN SWITCH TO SNOW.
WILL HAVE SOME ACCUMULATIONS ACROSS THE NORTH WITH 1 TO 2 INCHES
POSSIBLE AND LESSER AMOUNTS ELSEWHERE. BIGGEST QUESTION WILL BE
IMPACT OF THE WINDS WITH THE LIGHT SNOW. AT THIS TIME...APPEARS
STRONGEST WINDS WILL OCCUR OVER THE NORTH BEYOND LIGHT SNOW
OCCURRENCE AND MINIMIZE IMPACT BUT ENOUGH TO WARRANT A WINTER WX
ADVISORY. WITH BARE GROUND WOULD HAVE LIKED TO SEE 3 INCHES OF SNOW
BEFORE CONSIDERING BLIZZARD HEADLINES. REFER TO HEADLINES FOR
ADDITIONAL DETAILS.

.LONG TERM /SUNDAY THROUGH SATURDAY/...
WE WILL REMAIN IN A HIGH WIND REGIME SUNDAY AND SUNDAY NIGHT WITH A
SECONDARY 500 MB SHORTWAVE MOVING ACROSS NORTHEAST IOWA IN WAKE OF
THE LARGER INITIAL WAVE. PARAMETERS ARE ALL RIPE FOR A HIGH END
ADVISORY/LOW END WARNING WIND EVENT DURING THE DAY ON
SUNDAY...ESPECIALLY IN THE MID TO LATE MORNING HOURS...AND HAVE
CONTINUED THE HIGH WIND WARNING OF TONIGHT THROUGH 00Z SUNDAY
EVENING. AFTERWARD IT IS LIKELY THAT THE WARNING WILL NEED TO BE
TRANSITIONED INTO A WIND ADVISORY FOR AT LEAST THE FIRST PART OF
SUNDAY NIGHT...BUT WILL LEAVE THAT TO SUBSEQUENT SHIFTS TO AVOID
DOUBLE HEADLINE CONFUSION. HAVE REMOVED ANY LINGERING FLURRY/SNOW
CHANCES SUNDAY MORNING IN THE NORTHEAST AS MODELS ARE UNANIMOUS IN
PUSHING THE PRECIP OUT BEFORE 12Z. THERE IS A POSSIBILITY OF SOME
BLOWING SNOW IN THOSE AREAS EARLY ON SUNDAY...HOWEVER CONFIDENCE IN
SNOWFALL TO BEGIN WITH IS NOT THAT GREAT...AND THE AMOUNTS SHOULD BE
LIGHT ENOUGH THAT BLOWING SNOW WILL END FAIRLY QUICKLY AFTER THE
PRECIPITATION HAS STOPPED.

WE WILL SEE A PRETTY DRAMATIC COOL DOWN OVER THE NEXT COUPLE OF DAYS
BEHIND THE STORM SYSTEM TONIGHT...HAVE MAINTAINED SUNDAY HIGHS ONLY
A FEW DEGREES ABOVE MORNING LOWS WITH A NON DIURNAL TREND. LOWERED
SUNDAY NIGHT LOWS JUST A BIT BUT REMAINED ABOVE GUIDANCE DUE TO
STIFF BREEZES AND POSSIBILITY OF LINGERING STRATUS BEHIND THE
SECONDARY SHORTWAVE IN THE NORTHEAST. THE COLDEST TEMPERATURES WILL
COME MONDAY NIGHT AS A SURFACE RIDGE MOVES OVERHEAD...AND HAVE
LOWERED FORECAST BY SEVERAL DEGREES ACCORDINGLY. HOWEVER...THERE IS
A POTENTIAL FOR SOME CIRRUS LATE THAT NIGHT AND WE REMAIN SEVERAL
DEGREES ABOVE MOS IN MOST AREAS. FURTHER DROPS IN MONDAY NIGHT
TEMPERATURES MAY BE NEEDED ON SUBSEQUENT SHIFTS. FROM TUESDAY
THROUGH THE END OF THE WORK WEEK WE WILL SEE A PERIOD OF DEEP LAYER
RIDGING AND A GRADUAL WARMING TREND...WITH TEMPERATURES TOPPING OUT
THURSDAY OR PERHAPS FRIDAY IN OUR SOUTHEAST. HAVE RAISED
THURSDAY/THURSDAY NIGHT/FRIDAY TEMPERATURES BY SEVERAL DEGREES OVER
ALL BLEND AS DICTATED BY THE SYNOPTIC REGIME...TEMPERATURES
ALOFT...AND RECENT PATTERN HISTORY. SOMETIME FRIDAY OR FRIDAY NIGHT
A TROUGH WILL MOVE THROUGH BRINGING SOMEWHAT COOLER AIR FOR NEXT
WEEKEND BUT WITH LITTLE TO NO PRECIP EXPECTED.

&&

.AVIATION...01/06Z
SURFACE LOW WAS CENTERED OVER SOUTHEAST IOWA AT 04Z WITH FRONTAL
BOUNDARY EXTENDING NORTH THROUGH EASTERN IOWA.  SURFACE LOW SHOULD
MOVE NORTHEAST REACHING THE NORTHERN ILLINOIS AREA BY 09Z.  EXPECT
WINDS TO CONTINUE TO INCREASE DURING THE OVERNIGHT HOURS. AREAS OF
SNOW OR RAIN SHOULD EXIT THE TAF AREAS BY 09Z.  FOR THE BALANCE OF
THE FORECAST...EXPECT VERY STRONG NORTHWEST WINDS TO CONTINUE WITH
VFR CIGS AND VISIBILITIES. WIND GUSTS SHOULD REACH 50 KNOTS IN
PLACES DURING THE DAY ON SUNDAY.
