AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SIOUX FALLS SD
1036 PM CDT FRI MAY 10 2013

.UPDATE...
ISSUED AT 737 PM CDT FRI MAY 10 2013

STRONG COLD FRONT PUSHING INTO THE NORTHWEST CORNER OF THE CWA AS
OF 00Z. SEVERAL FAIRLY MINOR CHANGES MADE TO SHORT TERM GRIDS...
TO ACCELERATE THE BOUNDARY A BIT AND WITH IT THE POST FRONTAL
PRECIP THREAT ENTRANCE AND EXIT TO AREA. AT MOST...A COUPLE
HOURS THREAT AT ANY LOCATION WOULD SEEM TO BE IN ORDER. NEEDED TO
ELEVATE COVERAGE WORDING SOMEWHAT AS WELL... AND IS PROBABLY MORE
OF A VERY SHORT TERM LIKELY TO CATEGORICAL THREAT FOR SHOWERS...
BUT WITH THE SOMEWHAT DRIER AIRMASS IN PLACE...CHOSE TO KEEP
WORDING SCATTERED FOR THE TIME BEING. SHORT RANGE HRRR/RAP HAVE A
FAIRLY GOOD HANDLE ON TIMING OF THE POST FRONTAL PRECIP THREAT...
AND LARGELY BASED TIMING ON THESE OUTPUT. ENOUGH INSTABILITY TO
MENTION AN ISOLATED THREAT FOR THUNDER...BUT SHOULD BE MOSTLY
LIGHT SHOWERS WORKING THROUGH. STILL EXPECT AN HOUR OR TWO PERIOD
BEHIND THE FRONT FOR WINDS TO GUST TO 30 TO 40 MPH FROM THE
NORTHWEST... LIKELY STARTING TOWARD THE END OF THE PRECIPITATION
BAND AS IT WORKS THROUGH.

&&

.SHORT TERM...(TONIGHT AND SATURDAY)
ISSUED AT 301 PM CDT FRI MAY 10 2013

COLD FRONT COMING THROUGH QUICKLY TONIGHT IS EXPECTED TO PRODUCE A
NARROW BAND OF EXTRA STRONG WINDS...PERHAPS GUSTING TO 45 MPH...BUT
WILL GO WITHOUT A WIND ADVISORY AND CONTINUE TO HANDLE WITH HWO AND
POSSIBLY SPS FOR ITS SHORT DURATION AT ANY PLACE. NORTH/NORTHWEST
WINDS WILL THEN SETTLE DOWN TO GARDEN VARIETY BREEZY TO WINDY. WITH
PLENTY OF LIFT RIGHT ALONG FRONT BUT MARGINAL MOISTURE...CONTINUING
THE CHANCE...AND ONLY CHANCE...OF THUNDERSTORMS SEEMS THE BEST WAY
TO HANDLE THE THREAT. THIS THREAT WILL ALSO PROGRESS QUICKLY OVER
THE AREA WITH AND JUST BEHIND THE FRONT. GUIDANCE LOWS AND WHAT WE
HAVE BEEN GOING FOR LOOK GOOD WITH THE FRONT MOVING SO QUICKLY THAT
THE COOLING WILL OVERTAKE A LITTLE BAND OF MIXING CAUSED WARMING IF
IT OCCURS. CLOUDS WILL ALSO QUICKLY MOVE ACROSS THE AREA WITH DECENT
CLEARING EVEN SOUTHEAST BY DAYBREAK. THE COOLER DRY AIR AND
SUBSIDENCE AHEAD OF APPROACHING HIGH SHOULD MAKE SATURDAY PRETTY
SUNNY. JUST EXPECT A FEW CU IN THE EAST DUE TO THE STRONG HEATING.
THE COOLER TEMPERATURES STILL SEEM TARGETED AT 50S TO LOWER 60S.

.LONG TERM...(SATURDAY NIGHT THROUGH FRIDAY)
ISSUED AT 301 PM CDT FRI MAY 10 2013

SATURDAY NIGHT STILL LOOKS LIKE A NEAR PERFECT RADIATIONAL COOLING
NIGHT...ESPECIALLY FOR LOCATIONS WEST OF THE BUFFALO RIDGE. NOT
ISSUING ANY HEADLINES JUST YET BUT EXPECTING LOWS FROM THE UPPER
20S TO THE LOWER 30S SO A GOOD CHANCE FOR FROST.

THIS WILL LEAD INTO A VERY NICE SUNDAY WITH COOL CONDITIONS TO
START BUT WITHOUT MUCH WIND AND A GOOD AMOUNT OF SUNSHINE HIGH
TEMPERATURES IN THE 60S WILL FEEL PRETTY NICE...VERY SIMILAR TO TODAY.

SUNDAY NIGHT INTO MONDAY WILL SEE WARM AIR SURGE INTO THE REGION
AS STRONG RIDGING ALOFT BUILDS ACROSS THE AREA. A SOUTHERLY WIND
WILL INCREASE ON SUNDAY NIGHT KEEPING LOWS MAINLY IN THE
40S...POSSIBLY SOME LOWER 50S IN CENTRAL SOUTH DAKOTA. THE WARM
AIR WILL SPREAD ACROSS THE CWA THROUGH THE DAY MONDAY WITH
TEMPERATURES CLIMBING INTO THE 90S WEST OF THE JAMES RIVER VALLEY.
HIGHS WILL MAINLY BE IN THE 70S IN SOUTHWEST MINNESOTA AND
NORTHWEST IOWA.

A MILD WEEK AHEAD STARTING OFF VERY WARM THEN MODERATING BACK TO
JUST A BIT ABOVE NORMAL THE REST OF THE WEEK. TUESDAY LOOKS VERY
HOT WITH STRONG ZONAL FLOW ALOFT AND A SOUTHWEST COMPONENT TO THE
WIND IN THE LOWER LEVELS. WITH SOMEWHERE FROM ABOUT +26 TO +30 AT
925MB AND +22 TO +24 AT 850MB THERE IS A VERY GOOD CHANCE FOR MOST
LOCATIONS TO REACH 90 DEGREES. THE ECMWF 850MB PLUMES ALSO
STRONGLY SUGGEST NEAR RECORD TO 90TH PERCENTILE 850MB TEMPERATURES
SO IF THE TIMING OF THE FRONT THAT IS COMING DOWN IS JUST RIGHT A
COUPLE OF RECORD HIGHS WILL BE POSSIBLE. WITH A LOT OF HEAT AND AN
INCOMING FRONT THERE WILL BE A CHANCE OF THUNDERSTORMS BUT WITH
ONLY SPARSE MOISTURE AVAILABLE AND MARGINAL CONVERGENCE IN THE
LOWER LEVELS THE CHANCES WILL BE PRETTY SLIM. IF SOMETHING COULD
DEVELOP SOME STRONG WIND GUSTS WOULD BE THE LIKELY SEVERE WEATHER
CULPRIT.

WEDNESDAY AND THURSDAY ARE FAIRLY AGREEABLE AMONGST THE MODELS WITH
MUCH MORE DIVERGENCE SHOWING UP FRIDAY AS THE GFS BUILDS A RIDGE
OVER THE ROCKIES WHILE THE ECMWF BUILDS A RIDGE OVER THE ROCKIES.
THE BIGGEST DIFFERENCE WOULD BE THE CHANCE FOR PRECIPITATION AND AT
THIS TIME UNFORTUNATELY NO REAL PREFERENCE ALTHOUGH THE ECMWF DOES
MATCH A LITTLE MORE CLOSELY TO THE GFS ENSEMBLE MEAN SO MAYBE LEAN A
LITTLE MORE TOWARDS THE ECMWF.

&&

.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z SATURDAY NIGHT)
ISSUED AT 1028 PM CDT FRI MAY 10 2013

VFR CONDITIONS ARE EXPECTED THROUGH THE TAF PERIOD. A NARROW BAND OF
LIGHT SHOWERS ACCOMPANYING THE COLD FRONTAL PASSAGE WILL TRACK
SOUTHEAST THROUGH THE EASTERN FORECAST AREA THROUGH THE NEXT FEW
HOURS. DRY AIR A THE LOSS OF DAYTIME HEATING WILL KEEP SHOWER IMPACT
MINIMAL AS THIS ACTIVITY CONTINUES TO DISSIPATE INTO THE EARLY
MORNING HOURS. WINDS WILL TURN NORTH RIGHT BEHIND THE FRONT BECOME QUITE
BREEZY...ESPECIALLY ACROSS SOUTHWEST MINNESOTA AND ADJACENT COUNTIES
WHERE GUSTS TO 30 KT WILL BE POSSIBLE FOR A FEW HOURS. WINDS WILL
REMAIN RATHER BREEZY OVERNIGHT FROM THE NORTH NORTHWEST...BUT ARE
EXPECTED TO INCREASE ONCE AGAIN TO 15 TO 30 KT LATE SATURDAY MORNING
THROUGH MID EVENING.
