VISIBILITIES. OCCASIONALLY BELOW A HALF MILE. 

IN ADDITION...STRONG NORTHWEST WINDS WILL USHER IN ARCTIC AIR
WITH DANGEROUSLY COLD WIND CHILLS APPROACHING 20 BELOW ZERO

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE DES MOINES IA
1142 PM CST SUN JAN 11 2009

UPDATED AVIATION DISCUSSION

.DISCUSSION...
IT IS A TALE OF TWO SYSTEMS FOR THIS FORECAST...THE FIRST COMING
LATE TONIGHT AND MONDAY AND THE SECOND ON TUESDAY NIGHT INTO
WEDNESDAY. BOTH OF THESE PERIODS ARE FRAUGHT WITH THE POTENTIAL FOR
SIGNIFICANT WEATHER IMPACTS.

AS TO THE FIRST SYSTEM...AND AMPLIFYING MID-LEVEL SHORTWAVE AND
SURFACE LOW WILL MOVE QUICKLY DOWN THE NORTHERN PLAINS TONIGHT AND
ACROSS IOWA ON MONDAY. THIS SCENARIO HAS BEEN WELL ADVERTISED FOR
SEVERAL DAYS WITH THE DETAILS GRADUALLY COMING INTO BETTER
ALIGNMENT. THERE WILL BE A DOUBLE SHOT OF SNOW WITH THIS
SYSTEM...THE FIRST COMING IN THE FORM OF A BAND OF MODERATE TO HEAVY
SNOW TRAVERSING WEST TO EAST ACROSS THE STATE DURING THE MORNING
HOURS. FORECAST MODELS INDICATE VERY GOOD LIFT ASSOCIATED WITH THE
SHORTWAVE FEATURE AND WELL COLLOCATED WITH A SATURATED DENDRITIC
LAYER. IT APPEARS LIKELY THAT THIS BAND WILL PRODUCE SIGNIFICANT
SNOWFALL RATES...HOWEVER ITS TRANSITORY SPEED WILL LIMIT
ACCUMULATIONS SOMEWHAT. DURING THE AFTERNOON THE LIFTING WILL FADE
IN THE WEST AND GRADUALLY DIMINISH IN THE EAST AS THE SHORTWAVE
PULLS AWAY...BUT ENOUGH WILL REMAIN WITH GOOD MOISTURE IN THE COLUMN
FOR LIGHT TO MODERATE SNOW TO PERSIST...PRODUCING ADDITIONAL
ACCUMULATIONS ESPECIALLY IN THE EAST WHERE THE LIFT WILL REMAIN
LONGER.

A STRONG COLD FRONT TRAILING FROM THE LOW WILL CROSS THE STATE
BETWEEN THESE TWO SNOW AREAS...WITH A VERY TIGHT PRESSURE GRADIENT
ON THE BACK SIDE OF THE LOW PRODUCING VERY STRONG WINDS IN THE
AFTERNOON AND EVENING. BUFKIT SOUNDINGS ARE CONSISTENTLY SHOWING
GUSTS EXCEEDING 40 KT AT TIMES. COMBINED WITH THE NEW
SNOW...PRE-EXISTING SNOW PACK...AND STRONG COLD AIR ADVECTION BEHIND
THE FRONT...WE WILL SEE A THREE-PRONGED HAZARD OF SNOW...BLOWING
SNOW...AND DANGEROUS WIND CHILLS FROM MONDAY THROUGH MONDAY NIGHT.
THE BLIZZARD WATCH ISSUED EARLY THIS MORNING HAS BEEN EXPANDED TO
INCLUDE OUR SOUTHEASTERN COUNTIES AS IT APPEARS THAT THE SNOWFALL
AND WINDS WILL BE AS HIGH THERE AS IN OTHER PARTS OF THE WATCH. A
WINTER WEATHER ADVISORY HAS ALSO BEEN ISSUED COINCIDENT WITH THE
BLIZZARD WATCH FOR THE MORNING HOURS BECAUSE OF THE BAND OF MODERATE
TO BRIEFLY HEAVY SNOW MOVING THROUGH...WITH SIX HOUR ACCUMULATIONS
OF 2 TO 3 INCHES ACROSS THE ADVISORY AREA.

AS TO THE SECOND SYSTEM...AFTER A BRIEF RESPITE PROVIDED BY QUICKLY
MOVING HIGH PRESSURE ON TUESDAY...ANOTHER SHORTWAVE/SURFACE LOW
COMBO WILL SHOOT DOWN THE NORTHERN PLAINS...FOLLOWING A TRACK ALMOST
IDENTICAL TO THAT OF THE FIRST SYSTEM AND CROSSING IOWA ON WEDNESDAY
MORNING. AS WITH THE FIRST SYSTEM WE WILL FACE A TRIPLE THREAT OF
SNOW...BBLOWING SNOW...AND DANGEROUS WIND CHILLS. HOWEVER...IN THIS
CASE THE LIFT AND MOISTURE DO NOT APPEAR TO BE AS IMPRESSIVE AND
MOST OF THE SNOW ACCUMULATIONS WILL BE LIMITED TO THE NORTHEAST ON
THE EAST AND NORTH SIDES OF THE SURFACE LOW. IT IS TOO FAR OUT TO
PREDICT WHETHER A SNOW/BLOWING SNOW ADVISORY OR WORSE WILL BE
WARRANTED BUT IT IS POSSIBLE. IF NOTHING ELSE A WIND CHILL HAZARD
PRODUCT IS A VIRTUAL LOCK FOR WEDNESDAY NIGHT AND THURSDAY NIGHT
WITH BITTERLY COLD ARCTIC AIR STREAMING IN BEHIND THIS SYSTEM.

OTHER THAN THE VERY COLD TEMPERATURES AND WIND CHILLS THE FORECAST
FOR THE REMAINDER OF THE WEEK INTO NEXT WEEKEND IS RELATIVELY
BENIGN. THE GFS IS PERSISTENT IN ATTEMPTING TO BRING
ANOTHER...WEAKER SYSTEM THROUGH ON THURSDAY NIGHT OR FRIDAY.
HOWEVER...THIS IS OCCURRING BECAUSE OF A PATTERN SHIFT RESULTING
FROM THE GFS MOVING THE LARGE MID/UPPER GYRE NEAR HUDSON BAY
EASTWARD IN THE MIDDLE OF THE WEEK. THE GEM AND ECMWF ARE KEEPING
THIS CYCLONE MORE STATIONARY DURING THAT TIME...AND AS A RESULT
HOLDING HIGH PRESSURE NEAR THE AREA. THIS WILL BE MONITORED BY
SUBSEQUENT SHIFTS AS IT IS STILL AT LONG RANGE AND WE HAVE TWO MORE
POTENT SYSTEMS TO GET THROUGH FIRST.

&&

.AVIATION...12/06Z
APPEARS THAT A SOLID MVFR CEILING WILL BE OVER CENTRAL IOWA
OVERNIGHT...GENERALLY 500 FT EITHER SIDE OF 1800 FT...THOUGH AT
TIMES IT COULD DIP BELOW 010...ESPECIALLY AT KFOD AND KMCW. WARM
FRONT OR FORCING ON NORTHEAST SIDE OF ADVANCING SFC LOW WILL PASS
THROUGH AFT 12Z...WITH A 1-3 HR WINDOW OF HEAVIER SNOWFALL RATES AND
LIFR TO POTENTIALLY VLIFR CONDITIONS. EXACT TRACK OF PARENT SFC LOW
THROUGH CENTRAL IOWA WILL BE A LARGE FACTOR IN DETERMINING EXACT
DIRECTION AND SPEED OF WIND AT ANY GIVEN LOCATION BETWEEN 15-21Z.
HAVE GIVEN IT MY BEST ATTEMPT AT THIS POINT. I HAVE DELAYED THE
ONSET OF STRONG WINDS BY AN HOUR OR TWO DUE TO SLOWER MOVEMENT IN
00Z MODELS. HOWEVER...AFT 20Z NW AND 23Z FARTHER SOUTHEAST...NW
WINDS WILL BE INCREASING SUBSTANTIALLY AND THERE WILL LIKELY BE
ANOTHER SURGE OF SNOWFALL...THOUGH LIGHTER IN INTENSITY. BLOWING
SNOW WILL BECOME A SIGNIFICANT CONCERN IN THE LAST 9 HOURS OF THE
TAF PERIOD.
