AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE ABERDEEN SD
1140 AM CST WED FEB 26 2014

.UPDATE...
18Z AVIATION DISCUSSION UPDATED BELOW.

TEMPS ARE RISING RATHER QUICKLY THIS MORNING IN AREAS OF LESS SNOW
COVER THANKS TO THE SUNSHINE AND WARM AIR ADVECTION. HAVE
THEREFORE RAISED HIGHS A FEW DEGREES IN THESE AREAS.
OTHERWISE...DEEPER SNOW PACK AREAS SEEING SLOWER RISES...SO
CURRENT HIGHS APPEAR ON TRACK FOR THE TIME BEING. STILL EXPECTING
WINDY CONDITIONS THIS AFTERNOON...MORE SO OVER THE EASTERN CWA.
EXPECT AREAS OF BLOWING SNOW BY THIS AFTERNOON FOR AREAS THAT HAVE
MORE APPRECIABLE SNOW COVER. WIND CHILL ADVISORY WAS ALLOWED TO
EXPIRE AT 15Z THIS MORNING WITH NO CHANGES TO THE WIND ADVISORY
OVER EASTERN AREAS LATER THIS AFTERNOON.

&&
.PREVIOUS DISCUSSION...
.SHORT TERM...TODAY THROUGH FRIDAY
CURRENT ANALYSIS SHOWS SURFACE HIGH PRESSURE OFF TO THE SOUTHEAST
AND A LOW PRESSURE SYSTEM MOVING INTO NORTHERN ONTARIO. WARM AIR
ADVECTION AHEAD OF THIS SYSTEM HAS ALLOWED MORNING TEMPERATURES TO
STEADY...BUT MUCH OF NORTHEAST SOUTH DAKOTA AND WEST CENTRAL
MINNESOTA IS STILL REACHING WIND CHILL ADVISORY CRITERIA...SO
CONTINUED THE HEADLINES AS PLANNED.

SOME UNCERTAINTIES AND POTENTIAL HAZARDS CROP UP THIS AFTERNOON. THE
ASSOCIATED SURFACE TROUGH IS EXPECTED TO SWING ACROSS THE DAKOTAS
AND MINNESOTA THIS AFTERNOON...WITH COLD AIR ADVECTION IN ITS
WAKE. EXPECT WEST TO NORTHWEST WINDS WILL INCREASE...WITH WIND
ADVISORY GUSTS EXPECTED ACROSS THE FAR NORTHEAST CWA. THIS REGION
RECEIVED CONSIDERABLY LESS SNOWFALL THAN AREAS FURTHER WEST...SO
WHILE THERE MAY BE SOME MINOR BLOWING AND DRIFTING SNOW
ISSUES...DO NOT EXPECT THEM TO BE OF GREAT IMPACT.
THEREFORE...ISSUED A WIND ADVISORY AT THIS TIME. AREAS FURTHER
WEST...WHERE GREATER SNOWFALL ACCUMULATIONS OCCURRED HAVE THE
POTENTIAL FOR MORE IMPACTFUL BLOWING SNOW AND VISIBILITY ISSUES.
MANY UNCERTAINTIES REMAIN HOWEVER...INCLUDING THE TIMING OF THE
STRONGEST WINDS ACROSS THE SOUTHERN CWA...AND HOW WARM
TEMPERATURES WILL GET ACROSS THE FAR SOUTHWESTERN CWA. AFTER
DISCUSSING WITH NEIGHBORING OFFICES...CONTINUED THE SPECIAL
WEATHER STATEMENT FOR NOW...AND WILL LET LATER SHIFTS MONITOR THE
FRESH SNOWFALL RESPONSE TO INCREASING WINDS THIS AFTERNOON.

CONFIDENCE IN THE TEMPERATURE FORECAST IS ALSO FAIRLY LOW.
SURFACE HIGH PRESSURE SETTLES OVER THE REGION TONIGHT...AND WITH
WINDS FAIRLY LIGHT AND CLEAR SKIES...TEMPERATURES WILL AGAIN
PLUMMET. THE PAST FEW FORECASTS HAVE BEEN TOO WARM FOR LOWS...SO
TRENDED TOWARD THE COLDEST GEM GUIDANCE. WIND CHILLS WILL ALSO BE
OF CONCERN...HOWEVER WIND SPEEDS WILL NOT BE AS STRONG AS PREVIOUS
NIGHTS.

A LOW PRESSURE SYSTEM WILL MOVE INTO THE REGION LATE THURSDAY
THROUGH FRIDAY...BRINGING SNOW CHANCES TO THE REGION. AT THIS TIME
IT LOOKS LIKE THE BEST CHANCES WILL BE WARM AIR ADVECTION INDUCED
SHOWERS AHEAD OF THE INVERTED SURFACE TROUGH...MAINLY AFFECTING THE
EASTERN CWA. THE SYSTEM IS NOT OVERLY IMPRESSIVE IN TERMS OF UPPER
LEVEL SUPPORT AT THIS TIME.

.LONG TERM...FRIDAY NIGHT THROUGH WEDNESDAY

ARCTIC AIR WILL CONTINUE ITS GRIP OVER THE REGION THROUGH THE
EXTENDED WITH PERIODIC REINFORCEMENTS. THE UPPER FLOW WILL
TRANSITION FROM ZONAL WESTERLIES TO WEAK TROUGHING AND NORTHWEST
FLOW BY THE START OF NEXT WEEK. A FEW WAVES WILL MOVE OFF THE
ROCKIES AND PRODUCE SOME LIGHT SNOW WITH THE BEST CHANCES FOR
PRECIP FRI NIGHT AND SATURDAY.

&&

.AVIATION...
18Z TAFS FOR THE KABR...KATY...KPIR AND KMBG TERMINALS

A COLD FRONT WILL DROP ACROSS THE REGION THROUGH THE DAY BRINGING
WINDS AROUND FROM WEST TO NORTHWEST. THESE WINDS WILL REMAIN
BLUSTERY/WINDY THROUGH THE AFTERNOON AS STRONG LOW LEVEL WINDS
MIX DOWN. SATELLITE SHOWS SOME MVFR CEILINGS HEADING INTO EASTERN
ND THIS AFTERNOON. THE MODELS ALSO SHOW THE LOW LEVEL RH INCREASING
IN THE EAST INTO THIS EVENING. THUS...EXPECT SOME MVFR CEILINGS TO
AFFECT ABR AND ATY THIS EVENING. OTHERWISE...SURFACE HIGH PRESSURE
WILL QUICKLY BUILD IN TONIGHT AND THEN TO THE EAST THROUGH THE
NIGHT AND THURSDAY MORNING. THE WINDS WILL FALL OFF QUICKLY THIS
EVENING AND THEN TURN NORTHEAST AND EAST THROUGH THURSDAY MORNING.
