1134 PM CST SAT MAR 1 2014
.SHORT TERM...(THIS EVENING THROUGH SUNDAY)
ISSUED AT 333 PM CST SAT MAR 1 2014
AS FORCING FROM THE PV ANOMALY INTERACTS WITH THE MID LEVEL
FRONTAL BOUNDARY OVERHEAD...SEEING ONE LAST ENHANCEMENT OF THE
SNOW SOUTH OF INTERSTATE 90 INTO NORTHWEST IOWA. STILL EXPECTING A
MAJORITY OF THE ACCUMULATING SNOW TO END AROUND 6 PM...WITH SOME
LIGHT SNOW OR FLURRIES LINGERING FOR A FEW MORE HOURS...ESPECIALLY
SOUTH OF INTERSTATE 90. TOTAL ACCUMULATIONS OF 3 TO 5 INCHES IN
THE ADVISORY AREA STILL LOOKS GOOD...ALTHOUGH A FEW SPOTS MAY END
UP CLOSE TO 6 GIVEN THE COUPLE OF LOCALLY HEAVIER BANDS SEEN ON
RADAR. AMOUNTS OF 3 TO 4 INCHES EXPECTED JUST NORTH OF THE
ADVISORY...WITH GENERALLY AN INCH OR TWO AS YOU APPROACH
INTERSTATE 90. FOCUS LATER TONIGHT WILL THEN SHIFT TO THE FRIGID
TEMPERATURES AND WIND CHILLS.
WINDS WILL BE ON A DOWNWARD TREND OVERNIGHT...BUT SHOULD STILL STAY
IN THE 5 TO 15 MPH RANGE...HIGHEST ACROSS SOUTHWEST MINNESOTA AND
NORTHWEST IOWA. SKY COVER A BIT UNCERTAIN...BUT EXPECT THE DRY AIR
PUSHING SOUTH FROM THE ARCTIC HIGH TO OUR NORTH WILL HELP SCOUR
CLOUD COVER. THUS AT THIS TIME THINKING WE BECOME PARTLY TO EVEN
MOSTLY CLEAR BY LATER TONIGHT...ESPECIALLY NORTHEAST HALF...WITH THE
GREATEST COVERAGE OF CLOUDS FROM SOUTH CENTRAL SOUTH DAKOTA TOWARDS
SIOUX CITY. THERE IS A DECENT AMOUNT OF UNCERTAINTY WITH LOWS
TONIGHT. THINK WINDS WILL BE LIGHT ENOUGH TO RESULT IN DECENT
RADIATIONAL COOLING...ESPECIALLY GIVEN THE NEW SNOW COVER...BUT
PROBABLY NOT LIGHT ENOUGH FOR TEMPERATURES TO COMPLETELY DROP OFF.
AND GIVEN SKY COVER UNCERTAINTY...DID NOT WANT TO GO TOO OVERBOARD
WITH LOWS. DID STILL LOWER THEM A BIT...WITH READINGS IN THE TEENS
TO AROUND 20 BELOW ZERO JUST ABOUT EVERYWHERE. THIS RESULTS IN WIND
CHILLS OF 30 TO 40 BELOW ZERO NORTH OF INTERSTATE 90 AND EAST OF A
IVANHOE TO IDA GROVE LINE...THUS WENT AHEAD AND UPGRADED TO A WIND
CHILL WARNING THERE. ELSEWHERE WIND CHILLS SHOULD END UP BETWEEN 25
AND 35 BELOW ZERO...AND SO THE ADVISORY LOOKS GOOD. SHOULD BE A
PARTLY TO MOSTLY SUNNY DAY SUNDAY. BUT EVEN MIXING TO 925 MB WILL
RESULT IN HIGHS STRUGGLING TO GET ABOVE ZERO. DID NOT MAKE MANY
ADJUSTMENTS TO THE GOING HIGHS...AND IT WILL LIKELY BE ONE OF THE
COLDEST MARCH DAYS IN RECORDED HISTORY.
.LONG TERM...(SUNDAY NIGHT THROUGH SATURDAY)
ISSUED AT 333 PM CST SAT MAR 1 2014
THE NEAR RECORD TO RECORD COLD WILL CONTINUE ONE MORE NIGHT AS
HIGH PRESSURE MOVES OVER THE AREA. WINDS WILL BE LIGHT MOST OF THE
NIGHT...ESPECIALLY ALONG AND EAST OF THE JAMES RIVER. WITH PLACES
NOT EVEN EXPECTED TO RISE ABOVE ZERO TOMORROW...MANY LOCATIONS
WILL HAVE A CHANCE TO REACH THEIR ALL-TIME MARCH RECORD LOWS. THE
ONLY THING WORKING AGAINST THIS IS INCREASING MID AND HIGH CLOUDS
MOVING IN FROM THE WEST OVERNIGHT. THESE CLOUDS WILL REACH KHON
DURING THE LATE EVENING...SIOUX FALLS AROUND MIDNIGHT AND HWY 71 IN
MN AND IA TOWARD 3 OR 4 AM. THE QUESTION IS IF THIS WILL BE LONG
ENOUGH TO GET TO ALL-TIME MARCH RECORDS WHICH ARE -23 AT SIOUX
FALLS AND -22 AT SIOUX CITY. CURRENT THINKING IS THAT THESE CLOUDS
WILL INHIBIT RADIATION COOLING ENOUGH TO KEEP LOWS BETWEEN -15 AND
-20. FOR SIOUX CITY THIS WILL STILL BE A RECORD THE DATE...WHICH
IS -7...BUT NOT FOR THE MONTH. THE COLDEST TEMPERATURES ARE LIKELY
TO BE AROUND SPW AND SLB WHERE IT WILL FALL BELOW -20.
SOUTHERLY FLOW WILL GRADUALLY INCREASE THROUGH THE DAY ON MONDAY.
BOTH THE GFS AND ECMWF SHOW A FAIRLY RAPID WARM UP IN SOUTH
CENTRAL SD WHERE 925 MB TEMPS WILL RISE INTO THE SINGLE DIGITS
BELOW ZERO. WERE IT NOT FOR THE RELATIVELY FRESH SNOW COVER AND
CLOUDS...THESE AREAS MAY APPROACH 30. INSTEAD BOTH CLOUDS AND
SNOWCOVER WILL KEEP HIGHS IN THE UPPER TEENS TO AROUND 20. IT
WILL BE MUCH COLDER TO THE EAST WITH MOST OF NORTHWEST IOWA AND
SOUTHWEST MINNESOTA IN THE SINGLE DIGITS ABOVE ZERO.
A WEAK UPPER LEVEL WAVE WILL MOVE SOUTHEAST FROM NORTH DAKOTA INTO
MINNESOTA MONDAY NIGHT. THE NAM IS THE FARTHEST SOUTH WITH THIS
WAVE AND JET STREAK BUT THE GFS AND ECMWF KEEP THE JET STREAK NEAR
THE MINNESOTA RIVER WHICH SHOULD KEEP THE BEST LIFT AND CHANCE OF
SNOW TOWARD THE MINNESOTA RIVER. STILL THERE WILL BE SOME WARM
ADVECTION AND FRONTOGENESIS ACROSS MUCH OF THE AREA SO FLURRIES OR
A BIREF PERIOD OF LIGHT SNOW ARE POSSIBLE ON MONDAY
NIGHT...BASICALLY NORTHEAST OF A HURON TO STORM LAKE LINE...WITH
THE BEST CHANCE IN SW MN. WITH CLOUDS AND SOUTHERLY WINDS LOWS ARE
EXPECTED TO REMAIN ABOVE ZERO...WITH THE EXCEPTION OF SOME
SHELTERED AREAS IN NW IA. THIS SYSTEM WILL EXIT BY TUESDAY MORNING
BUT ANOTHER MORE ORGANIZED WAVE WILL APPROACH LATE TUESDAY
AFTERNOON AND BRING A CHANCE OF SNOW TO THE ENTIRE AREA ON TUESDAY
NIGHT. THE TOTAL SNOWFALL IS NOT EXPECTED TO BE MUCH...PERHAPS
AROUND AN INCH. AT THIS POINT THE BEST CHANCE LOOKS TO BE FROM
HURON THROUGH SIOUX FALLS TO SPENCER...BUT MAY BE ADJUSTED THE NEXT
COUPLE OF DAYS. THE WARMING TREND WILL CONTINUE WITH HIGHS ON
TUESDAY EXPECTED TO BE IN THE TEENS AND 20S AND LOWS FROM 5 TO 15
ABOVE.
IN THE EXTENDED...THE GENERALLY FAST NORTHWEST FLOW WILL CONTINUE
WITH A SERIES OF WEAK WAVE MOVING THE THROUGH THE FLOW. THE
PREDICTABILITY OF ANY OF THESE WAVES IN BOTH LOCATION AND TIMING IS
LOW AT THIS POINT. THEREFORE...POPS REMAIN LOW AND SPREAD ACROSS A
RELATIVELY LONG PERIOD. AS THESE DAYS APPROACH EXPECT THAT THE
PRECIPITATION CHANCE WILL COME INTO BETTER FOCUS. ONE THING THAT
IS MORE CERTAIN IS WARMER TEMPERATURES...ESPECIALLY ON THURSDAY AS
LOW PRESSURE MOVE NORTH OF THE AREA ALLOWING MUCH WARMER AIR INTO
THE REGION. TEMPERATURES LOOK TO AT LEAST REACH NORMAL AND...IF
THE ECMWF IS RIGHT...WOULD BE ABOVE NORMAL. FOR NOW GENERALLY HAVE
30S AND 40S ACROSS THE AREA BUT HIGHS COULD BE ANOTHER 5 TO 10
DEGREES WARMER IF THE ECMWF IS RIGHT. ALL MODELS SHOW ANOTHER
WAVE THEN MOVING THROUGH SOMETIME FROM THURSDAY NIGHT THROUGH
FRIDAY NIGHT. THE ECMWF IS STRONGEST WITH THIS SYSTEM AND BRINGS
MUCH COLDER AIR IN FOR FRIDAY WHILE THE GFS AND CANADIAN GEM ARE
WEAKER. THERE IS A LARGE SPREAD IN ENSEMBLE SOLUTIONS...BOTH WITH
THE ECMWF AND GFS IN TERMS OF TEMPERATURES FOR FRIDAY AND
SATURDAY. FOR NOW KEPT TEMPERATURES IN THE 20S AND 30S BOTH DAYS
AND ALSO HAVE A CHANCE OF SNOW PRIMARILY NORTH OF I90 ON FRIDAY.
