Area forecast discussion, Jan 23, 3:00 AM CST, 20 minutes before
AREA FORECAST DISCUSSION FOR SOUTHEAST SD/SOUTHWEST MN/NORTHWEST IA
NATIONAL WEATHER SERVICE SIOUX FALLS SD
300 AM CST WED JAN 23 2013
.DISCUSSION.../ISSUED AT 300 AM CST/
COLD FRONT WILL CONTINUE TO DROP SOUTHEAST ACROSS CWA THIS MORNING
WITH BREEZY NORTHWEST WINDS BEHIND THIS FRONT TODAY. COLD AIR
ADVECTION LAGGING A BIT BEHIND THIS FRONT...BUT SHOULD PUSH IN BY
AFTERNOON. SO HIGH TEMPERATURES LIKELY TO OCCUR THIS
MORNING...BEFORE HOLDING STEADY OR FALLING A BIT THIS
AFTERNOON...ESPECIALLY NORTHEAST CWA. PLENTY OF HIGH CLOUDS
TODAY...SO PARTLY SUNNY AT BEST. MODELS MORE IN AGREEMENT WITH COLD
PUSH TONIGHT...ALTHOUGH MAV APPEARS TO BE WAY OVERDOING COLD
AIR...ESPECIALLY WITH SOME HIGH CLOUDS PERSISTING ACROSS CWA. STILL
WILL BE QUITE COLD AND WILL LOWER MINS A GOOD 5 DEGREES MOST PLACES.
IF SKIES DO CLEAR MORE THAN EXPECTED...THAN NORTHEAST CWA COULD
EASILY DROP TO 15 BELOW TONIGHT. WITH WINDS EXPECTED TO BE A BIT
BREEZY THIS EVENING...WILL ISSUE A WIND CHILL ADVISORY ACROSS
NORTHEAST CWA FOR TONIGHT INTO EARLY THURSDAY MORNING...AS WIND
CHILLS DROP TO 20 BELOW TO 30 BELOW.
WILL REMAIN COLD ON THURSDAY WITH LOW LEVEL SOUTHEAST OFF OF ARCTIC
HIGH NOT TOO CONDUCIVE TO GOOD WARMING. IN FACT HIGH TEMPERATURES
MAY OCCUR THURSDAY EVENING AS TEMPERATURES RISE DURING NIGHT AS LOW
LEVEL FLOWS BECOMES SOUTH TO SOUTHWEST AHEAD OF NEXT WAVE. COULD SEE
A LITTLE LIGHT SNOW OR FLURRIES AHEAD OF THE ASSOCIATED WARM FRONT
OVER SOUTHWEST MINNESOTA THURSDAY NIGHT...AND WILL KEEP A SMALL
CHANCE IN FORECAST FOR THAT AREA.
ANOTHER SHOT OF COLD AIR FRIDAY BEHIND SHORT WAVE...SO ONCE
AGAIN...HIGH TEMPERATURES MAY OCCUR EARLY...ESPECIALLY NORTHEAST CWA
WHERE MAIN BRUNT OF COLD AIR ADVECTION WILL OCCUR.
SATURDAY MORNING WILL START OUT WITH SUB ZERO LOWS ACROSS EASTERN
CWA WITH HIGHS STRUGGLING THROUGH THE TEENS WITH LOW LEVEL SOUTHEAST
FLOW. WESTERN CWA WILL WARM MORE WITH HIGHS APPROACHING 30 ACROSS
THE SOUTHWEST CWA.
STRONGER WARMING ON SUNDAY WITH HIGHS ABOVE NORMAL MOST PLACES.
WAVE PUSHING EAST ACROSS CENTRAL PLAINS MAY GRAZE THE FAR SOUTHEAST
CWA ON SUNDAY AND WILL KEEP SMALL CHANCE OF LIGHT RAIN OR SNOW THERE
DURING THE DAY. WILL REMAIN MILD ON MONDAY AHEAD OF NEXT SYSTEM.
MODELS STILL DIVERGE A BIT ON SYSTEM FOR NEXT TUESDAY...WITH GFS
MUCH STRONGER THAN ECMWF. STILL EC DOES SET UP DECENT OVER RUNNING
AS ARCTIC FRONT SAGS THROUGH CWA MONDAY NIGHT...WITH SOUTHWEST FLOW
ALOFT PERSISTING ACROSS CWA ON TUESDAY. THIS SHOULD SET UP A DECENT
MID LEVEL FRONT ACROSS THE NORTHERN PLAINS. EXACT LOCATION STILL
SKETCHY...BUT WILL UP POPS TO CHANCE FOR TUESDAY. WOULD NOT BE
SURPRISED IF SOME PART OF THE CWA SEES A BAND OF 2 TO 4 INCH SNOW ON
TUESDAY WITH THIS SETUP.
&&
.AVIATION.../FOR THE 06Z TAF ISSUANCE/
AS EXPECTED...THERE IS STILL SOME MVFR CEILINGS LINGERING IN THE
EXTREME EASTERN SECTION OF EAST CENTRAL SD AND THROUGH SOUTHWEST MN.
BOTH THE LATEST NAM12 AND RUC13 MODELS ARE IN GOOD AGREEMENT IN
SLOWLY MOVING THE MVFR STRATUS EASTWARD ACROSS SOUTHWEST MN THROUGH
09Z TONIGHT. BUT THEN THE STRATUS MAY HANG UP NEAR THE MARSHALL AND
WINDOM MINNESOTA AREAS AS WINDS JUST OFF THE SURFACE SHIFT NORTHWEST
ALONG A COLD FRONT. THEREFORE MVFR CONDITIONS COULD LINGER IN OUR
EXTREME NORTHEAST ZONES WELL INTO WEDNESDAY MORNING. OTHERWISE
CONDITIONS SHOULD BE VFR FOR THE REST OF THE SIOUX FALLS FORECAST
AREA THROUGH WEDNESDAY EVENING. THERE IS A HIGHER DECK OF STRATUS
NEAR 4000 TO 5000 FT AGL TO THE WEST OF THE MVFR CEILINGS EXTENDING
FROM NEAR HURON SD...TO MOST OF NORTHWEST IA. HOWEVER VARIOUS MODELS
ALSO PROJECT THIS HIGHER BASED STRATUS TO EDGE EASTWARD THROUGH THE
REST OF THE NIGHT ALONG A WNW WIND COMPONENT IN THAT LAYER. SO THAT
SEEMS LOGICAL. AS BRIEFLY MENTIONED ABOVE...THERE WILL BE A COLD
FRONTAL PASSAGE ACROSS THE FORECAST AREA LATE TONIGHT AND VERY EARLY
WEDNESDAY. THEREFORE SURFACE WINDS WILL BE NORTH TO NORTHWEST ON
WEDNESDAY AND A BIT BREEZY. HOWEVER MOST GUSTS SHOULD STAY BELOW 25
KNOTS. /MJF
