Area forecast discussion, Mar 30, 10:45 AM CDT, 3 hours 47 minutes before
AREA FORECAST DISCUSSION FOR SOUTHEAST SD/SOUTHWEST MN/NORTHWEST IA
NATIONAL WEATHER SERVICE SIOUX FALLS SD
1045 AM CDT SUN MAR 30 2008
.DISCUSSION...
850-750MB FRONTOGENESIS STRENGTHENS OVER THE SOUTHEAST HALF OF THE
CWA THROUGH THE AFTERNOON...AND HAVE BEEN SEEING CLOUD TOPS COOLING
ON IR SATELLITE IMAGERY IN RESPONSE. RADAR ECHOES HAVE BEEN PICKING
UP A BIT JUST SOUTH/SOUTHWEST OF OUR CWA...AND MID CLOUD DECK HAS
BEEN LOWERING TO THE SOUTHWEST OF KSUX WITH LIGHT RAIN REPORTED IN
THE LAST HOUR AT KBVN SOUTHWEST OF KOFK. RELATIVELY DRIER NORTHERLY
FLOW TO OVERCOME...BUT THIS POINTS TO A LITTLE BETTER CHANCE OF -RA
REACHING THE GROUND ACROSS THE FAR SOUTHEAST PART OF THE CWA THIS
AFTERNOON AND HAVE BUMPED POPS UP INTO SCATTERED RANGE.
AWAITING CLOSER LOOK AT 12Z MODEL RUNS BEFORE RESOLVING WATCH INTO
ANY OTHER HEADLINES...BUT QUICK GLANCE AT NAM STILL POINTS TO GOING
WATCH AREA FOR GREATEST HEAVY SNOW POTENTIAL. MAIN CONCERNS TO IRON
OUT WILL BE HOW QUICKLY PRECIP WILL TURN TO SNOW...AND MORESO SNOW
INTENSITY AND WHETHER INTENSE LIFT/SNOW GROWTH POTENTIAL WILL BE
GREAT ENOUGH TO OVERCOME RELATIVELY WARM GROUND/NEAR SURFACE AIR
DURING THE DAYLIGHT HOURS MONDAY. CURRENT FEELING IS A GENERAL LIGHT
SNOW DURING THE DAY WOULD SEE MORE MELTING THAN ACCUMULATING...AS
HAS BEEN THE CASE IN RECENT COUPLE OF SYSTEMS. HOWEVER PERIOD OF
STRONGEST LIFT COINCIDENT WITH DENDRITIC SNOW GROWTH ZONE OCCURS
DURING THE EARLY MORNING AROUND 12Z ACROSS THE WESTERN HALF OF THE
CWA...AND SNOW INTENSITY DURING THIS TIME COULD BE ENOUGH TO FOR A
QUICK FEW INCHES TO PILE UP BEFORE OR RIGHT AROUND SUNRISE.
&&
.AVIATION...
KHON WL BE VFR THRU TODAY...HOWEVER MVFR TO IFR CONDS MAY BEGIN TO
DEVELOP BY LATE THIS EVENING AS SNOW BEGINS TO MOVE TOWARD THE SITE.
KFSD SHOULD ALSO BE VFR FOR MUCH OF TODAY. STRENGTHENING MID LVL
FRONT MAY PRODUCE SOME MVFR CIGS AND VIS AT KFSD DURING THE LATE
AFTERNOON...MORE LIKELY AND GRADUALLY DETERIORATING INTO IFR CONDS
AS THE EVENING PROGRESSES...IN ADVANCE OF A POWERFUL STORM SYSTEM.
KSUX MAY SEE A FEW LIGHT SHOWERS THIS AFTERNOON WITH MID LEVEL FRONT
STRENGTHENING OVER THE AREA...THOUGH SHOULD REMAIN VFR CIGS/VSBYS
FOR THE DAY. PROBABLE MVFR TO IFR CONDS THEN DEVELOPING THIS EVENING
IN ADVANCE OF THE STORM SYSTEM. BASIS FOR THIS FCST WAS PRIMARILY
THE NAM MODEL RH TIME SECTIONS WITH A BLENDING OF THE NAM AND GFS
SFC WINDS.
&&
.PREV DISCUSSION...
WEAK COLD FRONT PRESENTLY LOCATED FROM AROUND BROOKINGS TO
YANKTON...AND HAS YET TO PRODUCE ANY PRECIPITATION IN OUR CWA. AREA
OF SHOWERS OVER EASTERN NEBRASKA IN ASSOCIATION WITH THE FEATURE ARE
PUSHING TO THE NORTHEAST...AND WITH ANTICIPATION THAT THE FRONT WILL
BECOME NEARLY STATIONARY ONCE IT PASSES INTO CENTRAL IOWA...LEFT
SMALL POPS OVER OUR EXTREME SOUTHEAST THROUGH THE DAY.
OTHERWISE...MID LEVEL CLOUDS WILL INCREASE ACROSS THE CWA DURING THE
EARLY AFTERNOON IN ASSOCIATION WITH AREA OF MID LEVEL FRONTOGENESIS
LIFTING NORTHWARD OUT OF NEBRASKA THIS MORNING. OTHER THAN THE ABOVE
MENTIONED POPS...EXPECT THE REMAINDER OF THE FA TO REMAIN
PRECIPITATION FREE WITH DRY AIR IN THE LOWER LEVELS.
OUR ATTENTION THEN TURNS TO THE NEXT SYSTEM TO BEGIN AFFECTING OUR
AREA BY TONIGHT. DEVELOPING LOW PRESSURE OVER THE CENTRAL AND
SOUTHERN ROCKIES WILL BEGIN PUSHING OUT INTO THE CENTRAL PLAINS BY
THIS EVENING...PULLING GULF MOISTURE NORTHWARD INTO OUR AREA BY
EARLY TONIGHT. MEANWHILE...MIDLEVEL WAVE TAKES SHAPE OVER THE
WESTERN HIGH PLAINS...WITH STRONG ISENTROPIC LIFT/MID LEVEL
FRONTOGENESIS DEVELOPING OVER OUR SOUTHWEST BY THIS EVENING...THEN
PUSHING ACROSS THE SOUTHERN TWO THIRDS OF OUR CWA DURING THE
OVERNIGHT HOURS. WOULD EXPECT PRECIPITATION TO INCREASE ACROSS THE
AREA THROUGH THE NIGHT...BECOMING HEAVY IN OUR SOUTHWESTERN ZONES
LATE AT NIGHT. THERMAL PROFILES SUGGEST THAT IT WILL BE COLD ENOUGH
ALOFT TO SUPPORT SNOW OVER MOST OF THE NORTH AND WEST...THOUGH THE
DENDRITIC LAYER MAY NOT BECOME SATURATED IN OUR SOUTHEASTERN HALF
UNTIL AFTER 09Z. FARTHER TO THE SOUTHEAST...THROUGH NORTHWESTERN
IOWA..DRY AIR IN THE MID LEVELS MAY PRECLUDE ANYTHING BUT DRIZZLE OR
VERY LIGHT RAIN INITIALLY...IN ADDITION TO THE FACT THAT IT MAY JUST
BE TOO WARM ALOFT TO SUPPORT SNOW ANYWAY.
SYSTEM IS BEGINNING TO LOOK VERY FRIGHTENING BY MONDAY...WITH
INCREDIBLE MID LEVEL FORCING AND LIFT ACROSS THE SOUTHERN AND
EASTERN PORTIONS OF THE CWA. IN ADDITION...LOOKS TO BE UNSTABLE
ACROSS OUR SOUTH PER EPV AND 500 TO 700 MB THETA E LAPSE RATES
FIELDS. MODEL QPF AMOUNTS ARE ALSO OUTSTANDING...AROUND AN INCH PLUS
IN AREAS EAST OF INTERSTATE 90 DURING THE MORNING TO EARLY AFTERNOON
HOURS. AS IS TYPICAL HOWEVER...TEMPERATURES ALOFT WILL BE AN ISSUE OVER
OUR SOUTHEASTERN ZONES. LOOKS LIKE MIXED PRECIPITATION OVER MUCH OF
OUR IOWA ZONES...TO EVEN PLAIN RAIN IN THE EXTREME SOUTHEAST. THINK
ANY MIXED PRECIPITATION WILL BE IN THE FORM OF RAIN/SNOW/AND SLEET.
WHILE SLEET IS NOT USUALLY VERY COMMON...ESPECIALLY THIS TIME OF
YEAR...MODEL SOUNDINGS INDICATE A DEEP ENOUGH COLD LAYER IN THE LOW
LEVELS TO SUPPORT SLEET. DO NOT THINK FREEZING RAIN WOULD NOT BE
MUCH OF AN ISSUE THOUGH...WITH SURFACE TEMPERATURES HOVERING IN THE
LOW TO MID 30S IN OUR FAR SOUTHEAST. KEPT POPS IN THE FORECAST INTO
MONDAY NIGHT WITH PASSAGE OF UPPER WAVE AND BROAD POTENTIAL
VORTICITY PRESSURE ADVECTION ACROSS THE REGION DURING THE NIGHT.
IN LIGHT OF ALL THE ABOVE...AND THE POTENTIAL FOR SIGNIFICANT SNOW
ACCUMULATIONS...ELECTED TO ISSUE A WINTER STORM WATCH FOR MUCH OF
OUR NORTH AND WEST FOR LATE TONIGHT INTO MONDAY EVENING...WITH THE
POSSIBILITY OF AT LEAST 5 TO 7 INCHES OF SNOW IN THIS AREA AFTER ALL
IS SAID AND DONE. THERE IS THE POSSIBILITY THAT AMOUNTS COULD BE
MUCH HIGHER THAN THAT PER MODEL QPF FIELDS...IF EVERYTHING SETS UP
RIGHT.
