AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE ABERDEEN SD
1124 PM CST WED JAN 22 2014

.UPDATE...
SEE UPDATED AVIATION DISCUSSION BELOW.

&&
.PREVIOUS DISCUSSION...
.SHORT TERM...TONIGHT THROUGH FRIDAY NIGHT
STRONG SURFACE HIGH CONTINUES TO BUILD INTO THE REGION THIS
AFTERNOON. WINDS ARE SLOWLY DECREASING ACROSS THE REGION. WEB
CAMS ACROSS THE EASTERN CWA REVEAL IMPROVING VISIBILITY AND CALLS
PLACED ACROSS THE REGION TELL THE SAME STORY. ALTHOUGH...WEST
CENTRAL MINNESOTA STILL RATHER NASTY SO WILL HOLD ON TO THE
BLIZZARD WARNING HERE UNTIL 00Z FOR THE TIME BEING. ELSEWHERE
THOUGH...HAVE CANCELLED THE BLIZZARD WARNING BASED ON THE
IMPROVING REPORTS AND WEB CAMS. HAVE ALSO UPGRADED THE WIND CHILL
ADVISORY TO A WARNING FOR A PORTION OF THE REGION. LATEST WIND
CHILL FORECASTS BASED ON HOURLY WIND SPEEDS AND TEMPS OVERNIGHT
SHOW VALUES FROM 30 BELOW TO 40 BELOW ZERO. WILL LEAVE NO
HEADLINES FOR WIND CHILLS OVER CENTRAL SD AS WINDS WILL GO NEARLY
CALM HERE TONIGHT AND LOWS SHOULD BE WARMER DUE TO THE FACT THAT
THERE IS NO SNOW ON THE GROUND.

AS THE SURFACE HIGH DEPARTS ON THURSDAY...WARM AIR ADVECTION
PATTERN RETURNS AGAIN WITH WARMING TEMPS. CENTRAL SD WILL FEEL THE
MILD TEMPS THE MOST DURING THE DAY THURSDAY AS THE EAST WILL ONLY
WARM INTO THE SINGLE DIGITS. ALTHOUGH...WITH THE WARM FRONT MOVING
ACROSS THE REGION THURSDAY NIGHT...WILL SEE RISING TEMPS THROUGH
THE NIGHT. BY FRIDAY MORNING...MOST LOCATIONS SHOULD ACTUALLY BE
IN THE 20S TO LOW 30S. STILL LOOKING AT A PRETTY GOOD SETUP FOR A
DOWNSLOPE WIND EVENT YET AGAIN OVER THE COTEAU REGION. 925 MB
WINDS RANGE FROM 40 TO 55 KNOTS BASED ON WHICH MODEL YOU LOOK
AT...AND FROM A VERY FAVORABLE WIND DIRECTION OUT OF THE
SOUTHWEST. WITH FRESH SNOW ON THE GROUND...THERE COULD BE SOME
BLOWING SNOW ISSUES AND HAVE INCLUDED MENTION OF THIS IN THE
GRIDS.

WITH THE REGION IN THE WARM SECTOR ON FRIDAY...STILL EXPECTING
RATHER MILD TEMPERATURES IN THE 30S AND 40S. DID SHAVE A DEGREE OR
TWO OFF THE EAST AS RECENT SNOWFALL MAY HINDER THINGS JUST A
BIT...BUT STILL EXPECTING HIGHS IN THE 30S NONETHELESS. WILL ALSO
BE SEEING SOME SHORTWAVE ENERGY DROPPING SOUTH OVER THE REGION
WITH THE POSSIBILITY FOR PRECIPITATION. GIVEN THE MILD
TEMPS...WILL HAVE TO DEAL WITH MIXED PRECIP TYPES AS WELL.

.LONG TERM...SATURDAY THROUGH WEDNESDAY
THE LONG WAVE PATTERN WILL REMAIN PERSISTENT THROUGH THE LONG
TERM PERIOD...WITH AN UPPER RIDGE OVER THE WEST COAST AND A LOW
SPINNING OVER THE HUDSON BAY REGION. THIS LEAVES THE NORTHERN
PLAINS UNDER NORTHWEST FLOW ALOFT. THE MOST NOTABLE CLIPPER SYSTEM
IS EXPECTED DURING THE SATURDAY NIGHT AND SUNDAY TIME FRAME. MODELS
ARE FAIRLY AGREEABLE...INDICATING AN INITIAL WARM AIR ADVECTION
BAND OF SNOW SETTING UP SOMEWHERE ACROSS THE NORTHEAST
CWA LATE SATURDAY NIGHT...FOLLOWED BY AN ARCTIC FRONT SLAMMING INTO
THE REGION ON SUNDAY. ADDITIONAL LIGHT SNOW AND STRONG NORTHWEST
WINDS ARE AGAIN ANTICIPATED ALONG THE FRONT. THE BUFKIT MOMENTUM
TRANSFER TOOL IS INDICATING 30 TO 40 KTS AT THE TOP OF THE MIXED
LAYER...WHICH IS CERTAINLY ENOUGH TO CAUSE BLOWING SNOW ISSUES FOR
ANY AREAS RECEIVING FRESH SNOWFALL. COLD AIR AND HIGH PRESSURE
THEN SETTLES IN MONDAY. 850 MB TEMPERATURES DROP INTO THE UPPER
20S BELOW TO 30S BELOW ZERO BY MONDAY MORNING...AND STAY IN THAT
REALM THROUGH TUESDAY. ALTHOUGH THERE ARE STILL LARGE MODEL
DIFFERENCES...ANOTHER CLIPPER SYSTEM MAY IMPACT THE REGION BY THE
VERY END OF THE PERIOD.
