AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SIOUX FALLS SD
300 AM CDT SAT APR 11 2015

.SHORT TERM...(TODAY AND TONIGHT)
ISSUED AT 253 AM CDT SAT APR 11 2015

A STRONG SOUTHERLY WIND FIELD WILL CONTINUE TO DEVELOP AND
STRENGTHEN THIS MORNING AND GOOD WINDS WILL HAVE NO PROBLEM MIXING
TO THE SURFACE...THOUGH SPEEDS WILL STAY COMFORTABLY BELOW WIND
ADVISORY CRITERIA. MOISTURE SEEMS NIL AT ALL LEVELS AND SUNSHINE
SHOULD BE PLENTIFUL MOST OF TODAY WITH AN OCCASIONAL PATCH OF MIDDLE
AND/OR HIGH CLOUDS DRIFTING ACROSS...BUT EVEN HIGH LEVEL MOISTURE
FIELDS SEEM FAIRLY LOW. LATE AFTERNOON WILL PROBABLY SEE THE
DEVELOPMENT OF SCATTERED LOW CLOUDS SOUTHEAST AS A LOW LEVEL
MOISTURE FETCH STREAMS UP FROM THE SOUTH TOWARD NORTHWEST IOWA.
HIGH TEMPERATURES IN THE 70S ACROSS THE BOARD STILL
LOOK OK WITH LOWER 70S NORTHEAST TO UPPER 70S SOUTHWEST.

CLOUD INCREASE TONIGHT AHEAD OF THE APPROACHING COLD FRONT
WILL BE MODEST AND SLOW EXCEPT IN NORTHWEST IOWA AND NEARBY WITH
THAT INCREASING LOW LEVEL MOISTURE FETCH. AT THIS TIME THE LOWEST
LEVELS DO NT LOOK MOIST ENOUGH TO PRESENT A FOG PROBLEM IN THE STIFF
FLOW. THE REST OF THE MOISTURE FIELD AND MORE IMPORTANTLY THE
THERMAL LIFT PATTERN SHOULD PRECLUDE CONVECTION AHEAD OF THE COLD
FRONT TONIGHT AS WINDS AND ISOTHERMS TRY THEIR BEST TO BECOME
SOMEWHAT PARALLEL. TEMPERATURES SHOULD HOLD AT 50 PLUS THROUGH THE
NIGHT.

.LONG TERM...(SUNDAY THROUGH FRIDAY)
ISSUED AT 253 AM CDT SAT APR 11 2015

A COOL FRONT WILL BEAR DOWN ON THE AREA SUNDAY AND WITH WARM
TEMPERATURES AND DECENT LOW LEVEL MOISTURE SUSPECT A FEW
THUNDERSTORMS WILL DEVELOP. AS IS THE CLIMATOLOGICAL NORM FOR THIS
TIME OF YEAR THE BETTER CHANCES WILL BE ACROSS NORTHWEST IOWA WHERE
CAPE VALUES LIKELY TO GET UP TO AROUND 1000 J/KG OR SO. SHEAR IS NOT
TERRIBLE BUT NOTHING TO RIGHT HOME ABOUT EITHER. SHOULD BE ENOUGH TO
SUPPORT AN ISOLATED HAIL THREAT DURING THE LATE AFTERNOON AND EARLY
EVENING.

SUNDAY NIGHT INTO MONDAY A BREEZY NORTHWEST WIND WILL SET UP AS THE
COOLER AND MUCH DRIER AIR WORKS THROUGH. SHOULD STAY A BIT MIXY
SUNDAY NIGHT SO LOWS IN THE MID AND UPPER 30S. COOLER AIR ALOFT WILL
KEEP TEMPERATURES DOWN A BIT ON MONDAY BUT STILL VERY MILD WITH
HIGHS IN THE 60S.

IN THE OUTER PERIODS(TUESDAY THROUGH FRIDAY)...SHORT WAVE RIDGING
MOVES THROUGH THE REGION TUESDAY BUT A DEEPENING TROUGH TO THE WEST
LOOKS TO BRING A WEAK WAVE NORTHWARD ON WEDNESDAY. WILL GO WITH WARM
TEMPERATURES IN THE 70S...POSSIBLY A FEW 80S ALONG AND WEST OF THE
JAMES RIVER VALLEY. AS THE TROUGH DEEPENS AND THE WEAK WAVE EJECTS
NORTHEAST SCATTERED SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE
WEDNESDAY INTO THURSDAY. WILL MAINTAIN LOWER END POPS AT THIS TIME
AS CONFIDENCE IS NOT REAL STRONG GIVEN MARGINAL MOISTURE. AT THIS
TIME THE MODELS ARE SOMEWHAT CONVERGING ON A SOLUTION WHICH TAKES
THE BULK OF THE ENERGY WITH THE WESTERN TROUGH INTO THE SOUTHERN
UNITED STATES. THIS WOULD HINT AT A MILD AND MAINLY DRY PERIOD SO
AIMING FOR LOWS FROM ABOUT 35 TO 45 WITH HIGHS MAINLY IN THE 60S.

&&

.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z SATURDAY NIGHT)
ISSUED AT 1054 PM CDT FRI APR 10 2015

VFR CONDITIONS ARE EXPECTED THROUGH THE TAF PERIOD. LIGHT AND
VARIABLE WINDS WILL TURN SOUTHERLY LATE TONIGHT. WINDS INCREASE
MID MORNING SATURDAY TO AROUND 15 TO 20 KT WITH GUSTS TO 30 KT.
NOT EXPECTING WINDS TO DECREASE MUCH AT ALL IN THE EVENING
THROUGH THE END OF THE TAF PERIOD.

&&

.FIRE WEATHER...
ISSUED AT 337 PM CDT FRI APR 10 2015

WITH NO BIG CHANGES IN WIND AND MOISTURE FIELDS A VERY HIGH TO
EXTREME FIRE DANGER ACROSS THE AREA TODAY IS STILL WARRANTED.
SOUTHERLY WINDS INCREASING RATHER QUICKLY WILL BE IN THE 20-30 MPH
RANGE...TEMPERATURES WILL CLIMB INTO THE 70S...AND RELATIVE HUMIDITY
VALUES WILL FALL INTO THE 25-30 PERCENT RANGE. AFTER
COORDINATION...A RED FLAG WARNING WILL BE ISSUED FOR THE CURRENT
WATCH AREA AND STILL EXCLUDE THE SOUTHEAST...WHERE WINDS WILL BE A
LITTLE SLOWER TO COME UP AND RECENT RAINS HAVE BEEN THE GREATEST.

A COOL FRONT WILL WORK THROUGH THE AREA ON SUNDAY AND VERY HIGH TO
POSSIBLY EXTREME FIRE CONDITIONS WILL BE POSSIBLE ALONG AND WEST
OF THE JAMES RIVER VALLEY. MONDAY WILL ALSO POSE A RISK FOR VERY
HIGH TO EXTREME FIRE CONDITIONS. THE WINDS ARE JUST A TOUCH MORE
MARGINAL BUT EXPECTED AFTERNOON RELATIVE HUMIDITY IN THE TEENS TO
LOWER 20S WILL MAKE WINDS OF 15 TO 25 MPH A LITTLE MORE DANGEROUS.
TUESDAY WILL SEE WINDS TURN AROUND TO THE SOUTH AND AGAIN BECOME
WINDY. WITH RELATIVE HUMIDITY IN 15 TO 30 PERCENT RANGE TUESDAY
WILL BE ANOTHER DAY WITH POTENTIAL CRITICAL FIRE WEATHER.
