What happened

The episode as NWS FSD wrote it up.

Widespread icing from freezing rain made travel difficult, and at times impossible. Damage to power lines and trees occurred, especially in the Spirit Lake area, where significant power outages were reported for the second time in a week. One to three inches of snow fell on top of the ice, except in northwestern Lyon County where up to 5 inches fell.

335 AM CST THU MAR 14 2002

SNOW COVER WILL LARGELY DRIVE TEMPS OVER THE NEXT FEW DAYS...WITH
FRESH SNOW COVER RANGING FROM 19 INCHES IN HURON /NEARLY MATCHING
THEIR SEASON TO DATE TOTAL UP THROUGH WEDNESDAY/...TO BARE GROUND IN
KSUX AND KSLB.  PROBABLY WILL NOT SEE TEMPS CLIMB TOO MUCH TODAY...
ESPECIALLY WEST AND NORTH WITH AT LEAST PARTIAL SUNSHINE REFLECTING
OFF THE FRESH SNOW.  SHOULD GENERALLY SEE HIGHS RANGE FROM MID 20S
WEST AND NORTH...TO MID-UPPER 30S IN THE SOUTHEAST.  TONIGHT WILL BE
COLDEST NIGHT BY FAR...AS SURFACE RIDGE AND ASSOCIATED SUBSIDENCE
MOVES THROUGH...BRINGING MOSTLY CLEAR SKIES AND LIGHT WINDS MUCH OF
THE NIGHT.  PERFECT RADIATIONAL COOLING SCENARIO WITH FRESH SNOW...
AND WILL GENERALLY SEE LOWS FROM SINGLE DIGITS WEST AND NORTH...TO
UPPER TEENS IN THE SOUTHEAST.

SOME WARMUP MOST AREAS ON SATURDAY ON THE BACK SIDE OF THE HIGH.
SOUTHEAST FLOW GENERALLY NOT THE BEST FOR MIXING...BUT IT SHOULD
HELP ERODE SOME OF THE SNOW COVER FROM THE SOUTHEAST.  COOLEST
READINGS AGAIN IN THE WEST AND NORTH...BUT EVEN THERE READINGS
SHOULD MAKE IT TO THE LOWER TO MID 30S.  CLOSER TO MID 40S ACROSS
THE SOUTHEAST.

BROAD UPPER TROF IN THE WESTERN CONUS WILL EJECT SHORTWAVES OVER OUR
AREA THROUGH THE WEEKEND AND EARLY NEXT WEEK...AND THE FIRST OF
THOSE WILL AFFECT THE AREA LATE SATURDAY THROUGH SUNDAY MORNING.
WILL BRING AN INCREASE IN CLOUDS TO THE WEST SATURDAY AFTERNOON...
WITH A CHANCE OF LIGHT SNOW SPREADING WEST TO EAST OVER MOST OF THE
CWA SATURDAY NIGHT.  THIS WILL LINGER INTO SUNDAY MORNING ACROSS THE
NORTHEAST...WHILE THE WEST AND SOUTH AREAS OF THE CWA BECOME PARTLY
SUNNY.  MORE CLOSELY FOLLOWING THE ETA WITH THIS SCENARIO.  THE AVN
IS TRYING TO DEVELOP A STRONGER SHORTWAVE FOR SUNDAY...STRENGTHENING
THE WAVE AS IT ROUNDS THE BASE OF THE TROUGH...WITH RESULTING QPF
VALUES FROM 1/4 TO 1/2 INCH THROUGH THE DAY...WHILE THE ETA REMAINS
DRY.  HAVE A HARD TIME SEEING WHY THIS WAVE WOULD INTENSIFY AS THE
AVN REFLECTS...AND WILL LEAN TOWARD THE ETA.  THIS HAS AN IMPACT ON
TEMPS AS WELL...SINCE THE STRONGER WAVE KNOCKS TEMPS BACK SOME. AS
A RESULT...WE ARE SEEING AROUND 5-7 DEG C DIFFERENCE IN 850MB TEMPS
FOR SUNDAY AND SUNDAY NIGHT.  GREATEST EFFECT FROM THIS DIFFERENCE
WOULD BE IN HIGHS ON MONDAY...BUT DO NOT HAVE ENOUGH CONFIDENCE TO
RAISE HIGHS AT THIS POINT.
