AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DES MOINES IA
328 PM CST MON NOV 10 2014

.SHORT TERM /TONIGHT/...
ISSUED AT 325 PM CST MON NOV 10 2014

STRONG COLD FRONT CURRENTLY STRETCHING ACROSS THE NORTHWESTERN
THROUGH THE WEST CENTRAL CWA...AND IS EXPECTED TO CONTINUE TO TRACK
EAST/SOUTHEASTWARD THROUGH THE ENTIRE CWA BY MID EVENING. SHARP
TEMPERATURE DROP NOTICED BEHIND THE FRONT...WITH STRONG CAA AS H85
TEMPS FALL FROM AROUND +5C TO +10C TO AROUND -10C BY EARLY TUESDAY
MORNING. THIS WILL SEND TEMPS PLUMMETING INTO THE 20S AND 30S...WITH
READINGS AT ESTHERVILLE ALREADY AT 28F DEGREES. LOW CLOUDS TO SPREAD
ACROSS THE ENTIRE CWA AS WELL...WITH WINDS BECOMING STRONG AND GUSTY
AS WELL. STRONGEST PRESSURE RISES TO MOVE THROUGH THIS EVENING INTO
THE OVERNIGHT HOURS ACROSS THE WEST CENTRAL INTO SOUTHWESTERN CWA
WITH WINDS ALOFT IN THE 30KT TO 40KT RANGE. BUFKIT ALSO ADVERTISING
30KT TO 40KT WINDS THROUGHOUT THE MIXED LAYER WITH STRONG CAA
EXPECTED TO HELP THESE WINDS MAKE THEIR WAY TO THE SURFACE.
THEREFORE WILL ISSUE A WIND ADVISORY FOR THE WESTERN THIRD OF THE
CWA WHERE THE PRESSURE RISES WILL COUPLE WITH THE MOMENTUM TRANSFER
OF STRONG WINDS ALOFT. REMAINDER OF THE CWA COULD TOUCH ADVISORY
CRITERIA WINDS OCCASIONALLY...BUT EXPECT IT TO BE MORE CONSISTENT
ACROSS THE WEST THUS HAVE ONLY ISSUED FOR THAT AREA. DEF ZONE PRECIP
TO MOVE INTO CENTRAL IOWA TONIGHT...AS THE SFC LOW LIFTS INTO SRN
WI/NRN IL AREA BY LATE TONIGHT. AS THE LOWER LEVELS SATURATE AND
PRECIP BEGINS...MAY INITIALLY HAVE SOME LIGHT FZDZ OR FZRA UNTIL THE
COLUMN SATURATES AND ICE IS INTRODUCED QUICKLY CHANGING THE PRECIP
TO SNOW. OVERALL LITTLE ICE ACCUMULATION IS EXPECTED WITH ONLY A
LIGHT GLAZING IN SOME AREAS. AS FOR SNOW AMOUNTS...PRECIP IS
EXPECTED TO BE LIGHT SO MUCH OF THE AREA MAY ONLY SEE A DUSTING TO
MAYBE HALF AN INCH AT MOST. AREAS ACROSS THE NORTH WILL HAVE THE
BEST CHANCE AT SEEING SOME LIGHT ACCUMULATIONS OF AROUND AN INCH TO
AN INCH AND A HALF OVERNIGHT. WITH THE STRONG WINDS AND POTENTIAL
FOR LIGHT SNOW...MAY BE A BRIEF PERIOD OF REDUCED VISIBILITIES
ESPECIALLY ACROSS THE NORTH WHERE MAY SEE SOME LIGHT ACCUMULATIONS.
RIGHT NOW IT APPEARS THAT THIS WOULD BE ON THE ORDER OF AN HOUR OR
TWO AT MOST AS THE MOST INTENSE SNOWFALL BAND WOULD QUICKLY MOVE
THROUGH...SO WILL NOT ISSUE A WINTER HEADLINE AT THIS TIME. WILL
HAVE TO MONITOR THROUGH THE EVENING AS THE AREA DEVELOPS TO SEE IF
ONE MIGHT BE WARRANTED FOR A PORTION OF THE OVERNIGHT HOURS.

.LONG TERM /TUESDAY THROUGH MONDAY/...
ISSUED AT 325 PM CST MON NOV 10 2014

VERY LIGHT SNOW MAY LINGER BEYOND 6 AM TUESDAY MORNING OVER THE
FAR EAST FROM MASON CITY TO WATERLOO AND OTTUMWA BEFORE ENDING.
STRONG MID LEVEL SUBSIDENCE AND DRYING BEHIND THE UPPER LEVEL
SHORT WAVE WILL ARRIVE SHORTLY AFTER THAT TIME. COLD ADVECTION
WILL CONTINUE THROUGH THE DAY AND WILL KEEP HIGH TEMPERATURES IN
THE 20S TO LOWER 30S FOR MOST LOCATIONS. THESE TEMPERATURES
COMBINED WITH BREEZY NORTHWEST WINDS WILL MAKE IT FEEL MUCH COLDER
WITH APPARENT TEMPERATURE VALUES FROM THE SINGLE DIGITS TO AROUND
20. THE BREEZY WINDS WILL KEEP TEMPERATURES FROM BOTTOMING OUT AT
NIGHT THROUGH. ANOTHER STRONG SHORT WAVE WILL DROP THROUGH THE
NORTHERLY FLOW AND INTO MONTANA AND NORTH DAKOTA ON TUESDAY THEN
CLOSE OFF. THIS SYSTEM WILL BRING ANOTHER ROUND OF COLD ADVECTION
LATE TUESDAY AND TUESDAY NIGHT. H85 TEMPERATURES BY WEDNESDAY WILL
BE NEAR -15C ACROSS THE ENTIRE STATE. HAVE DROPPED HIGH
TEMPERATURES FURTHER FOR WEDNESDAY INTO THE 20S. MAY STILL BE A
FEW DEGREES TOO HIGH. CENTRAL IOWA IS EXPECTED TO BE BETWEEN TWO
SYSTEMS FROM THE NORTH AND SOUTH WEDNESDAY NIGHT. HAVE KEPT NEARLY
THE ENTIRE AREA WITHOUT POPS WEDNESDAY NIGHT GIVEN THE AMOUNT OF
DRY AIR AND LACK OF FORCING.

THE NEXT CHANCE FOR PRECIPITATION WILL BE SATURDAY AND SATURDAY
NIGHT AS PACIFIC MOISTURE OVERRIDES THE COLD DOME. THIS SYSTEM WILL
BRING THE POTENTIAL FOR LIGHT SNOW ACCUMULATIONS. OTHERWISE...THE
DEEP FREEZE WILL REMAIN THE PROMINENT WEATHER STORY THROUGH THE
FORECAST PERIOD AND QUITE POSSIBLY WELL BEYOND. A LARGE OMEGA
BLOCK WILL BECOME ESTABLISHED THROUGH THE WEAK...FEATURING TWO
LARGE AREAS OF LOW PRESSURE. THE FIRST LOW WILL BECOME ESTABLISHED
NEAR TO JUST SOUTH OF HUDSON BAY WITH THE OTHER WILL BE CENTERED
NEAR THE ALEUTIAN ISLANDS. THIS WILL RESULT IN A RIDGE FROM THE
FAR WEST COAST NORTH ACROSS WESTERN NEBRASKA AND KEEP THE DEEP
NORTH FLOW DRAINING THE VERY COLD AIR SOUTH INTO THE UPPER
MIDWEST. ANOTHER VERY COLD PUSH ON TARGET TO ARRIVE BY NEXT
MONDAY WHICH COULD BRING HIGHS IN THE TEENS TO MID 20S.

&&

.AVIATION...10/18Z
ISSUED AT 1239 PM CST MON NOV 10 2014

STRONG COLD FRONT HAS ALREADY PUSHED INTO NORTHWEST IOWA AND WILL
CONTINUE TREADING ACROSS THE STATE THROUGH THE AFTERNOON INTO THE
EARLY EVENING HOURS. WINDS WILL SHIFT AROUND TO THE NORTHWEST
AND INCREASE TO BECOME QUITE GUSTY BEHIND THE FRONT. CIGS WILL
LOWER INTO THE MVFR RANGE WITH EVEN A FEW IFR OBSERVATIONS
POSSIBLE. FOR NOW HAVE JUST MENTIONED IFR WITH A SCT DECK.
PRECIPITATION EXPECTED TO SPREAD ACROSS THE TAF SITES THIS
EVENING...WITH AN INITIAL CHANCE FOR RAIN CHANGING TO VERY LIGHT
FZRA OR FZDZ BEFORE COMPLETELY CHANGING OVER TO SNOW. THE SNOW
SHOULD TAPER OFF FROM SOUTHWEST TO NORTHEAST BY TUESDAY
MORNING...WITH MVFR CIGS REMAINING THROUGH THE DAY.

.DMX WATCHES/WARNINGS/ADVISORIES...
