AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SIOUX FALLS SD
1236 PM CDT TUE APR 8 2014

.SHORT TERM...(TODAY AND TONIGHT)
ISSUED AT 344 AM CDT TUE APR 8 2014

NOT A LOT GOING ON TODAY ACROSS THE AREA AS THE TROUGH EXITS TO THE
EAST AND SURFACE HIGH PRESSURE BUILDS OVERHEAD. ONLY MAIN CONCERN IS
CLOUD COVER THIS MORNING. SEEING AN AREA OF STRATUS MOVING SOUTH
INTO THE CWA IN THE LOW LEVEL COLD AIR ADVECTION. MODELS IN PRETTY GOOD
AGREEMENT THAT AREAS EATS OF THE JAMES RIVER WILL SEE A PERIOD OF
CLOUDINESS FROM THIS STRATUS...SO WENT AHEAD AND INCREASED SKY
COVER. THESE CLOUDS SHOULD MIX OUT AROUND MID MORNING...GIVING WAY
TO MOSTLY SUNNY SKIES. TEMPERATURES TODAY WILL BE COOLER THAN
PREVIOUS DAYS GIVEN THE LOW LEVEL THERMAL PROFILE...BUT STILL
EXPECTING READINGS RIGHT AROUND AVERAGE FOR THIS TIME OF YEAR...50S
EATS TO LOW 60S WEST. AS THE HIGH SHIFTS EAST TONIGHT...A SOUTHERLY
BREEZE WILL STAY UP KEEPING THINGS SOMEWHAT MIXED. THUS THINKING
LOWS REMAIN IN THE MID 30S TO AROUND 40.

.LONG TERM...(WEDNESDAY THROUGH MONDAY)
ISSUED AT 344 AM CDT TUE APR 8 2014

ROLLER COASTER TEMPERATURES THE NEXT FEW DAYS WITH A SERIES OF
FRONTS MOVING THROUGH THE AREA.  WARM SOUTHWEST FLOW EXPECTED ON
WEDNESDAY.  SOUNDING PROFILES ARE QUITE DRY SUGGESTING TANKING DEW
POINTS DUE TO MIXING.  HAVE SIDED WITH A COMBINATION OF BCCONSMOS
AND BCCONSRAW IN TERMS OF DEW POINTS ON WEDNESDAY.  MAY STILL BE ON
THE HIGH SIDE WITH DEW POINTS...AND WITH GUIDANCE REMAINING ON THE
COOL SIDE AS OF LATE...WARMED FORECAST HIGHS TO AT OR JUST BEYOND A
FULL 850 HPA MIXOUT WHICH STILL MAY BE COOL BASED ON RECENT TRENDS
GIVEN THE VEGETATION IS STILL DORMANT.  WINDS ARE SOMEWHAT
MARGINAL...BUT CONDITIONS ARE CERTAINLY CLOSE ENOUGH THAT I WENT
AHEAD AND ISSUED A FIRE WEATHER WATCH ACROSS THE AREA FOR
WEDNESDAY.

STRONG COLD FRONT MOVES THROUGH THE AREA WEDNESDAY NIGHT.  WITH DRY
ATMOSPHERE AHEAD OF THE FRONT...DOESN/T APPEAR AS THOUGH THERE IS A
CHANCE FOR CONVECTION AHEAD OF THE FRONT...BUT COULD BE A FEW
SHOWERS POST FRONTAL.  BEST CHANCES APPEAR TO BE CLOSEST TO THE
MIDLEVEL SHORT WAVE ACROSS THE NORTHEAST HALF OF THE FORECAST AREA.

COOLER CONDITIONS EXPECTED ON THURSDAY UNDER THE INFLUENCE OF
NORTHWEST FLOW ALOFT.  925 HPA TEMPS COOL AROUND 15 DEGREES C BY
THURSDAY MORNING BUT GRADUALLY REBOUND THROUGH THE DAY. WITH
CONTINUED DRY CONDITIONS...SHOULD SEE ELEVATED FIRE DANGER BUT WITH
WINDS RAPIDLY FALLING OFF DURING PEAK HEATING OF THE DAY DO NOT
EXPECT ANY HEADLINES.

WARMER CONDITIONS EXPECTED ON FRIDAY AS SURFACE RIDGE MOVES THROUGH
THE AREA AND SOUTHERLY FLOW DEVELOPS.  GULF IS
OPEN...HOWEVER...SOUTHWEST WINDS SHUNT MUCH OF THE MOISTURE EAST
KEEPING CONDITIONS RELATIVELY DRY.

MODELS SUGGEST LOW LEVEL JET DEVELOPING FRIDAY NIGHT...BUT MOISTURE
AND INSTABILITY REMAIN A CONCERN.  HAVE KEPT THE MENTION OF
THUNDERSTORMS IN THE FORECAST FOR THE POTENTIAL OF ELEVATED
THUNDERSTORMS FORMING ON THE CONVERGENCE OF THE NOSE OF THE LOW
LEVEL JET.  STILL APPEARS AS THOUGH A COLD FRONT WILL MOVE THROUGH
THE AREA ON SATURDAY AFTERNOON AND EVENING CREATING THE POTENTIAL
FOR THUNDERSTORMS AND MAYBE A SEVERE STORM OR TWO.

MUCH COOLER CONDITIONS ARE EXPECTED THROUGH THE REMAINDER OF THE
FORECAST.  925 HPA TEMPS FALL BACK BELOW ZERO...BUT APPEARS TO DROP
BELOW ZERO AFTER THE FORCING MOVES OUT OF THE AREA...SO HAVE KEPT
ALL PRECIPITATION LIQUID FOR NOW.

&&

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z WEDNESDAY AFTERNOON)
ISSUED AT 1236 PM CDT TUE APR 8 2014

VFR WILL PREVAIL THROUGH 09/18Z AS THE AIR CONTINUES TO DRY OUT AT
LOW AND MIDDLE LEVELS. A FEW SURFACE GUSTS AROUND 25 KNOTS FROM
THE NORTH TO NORTHWEST OVER SOUTHWEST MN AND NORTHWEST IA WILL
DECREASE BY 21Z. SURFACE GUSTS MAY APPROACH 25 KNOTS FROM THE
SOUTHWEST OVER THE AREA AFTER 09/15Z.

&&

.FIRE WEATHER...
WARM...DRY AND WINDY CONDITIONS ARE EXPECTED ON WEDNESDAY ACROSS THE
AREA.  SOUTHWEST WINDS ARE EXPECTED TO INCREASE TO 15 TO 25 MPH WITH
GUST TO 35 MPH THROUGH THE AFTERNOON HOURS.  AS TEMPERATURES WARM
AND DRY AIR MIXES DOWN FROM ALOFT...RELATIVE HUMIDITY VALUES ARE
EXPECTED TO FALL TO 15 TO 25 PERCENT ACROSS THE AREA.  A FIRE
WEATHER WATCH IS IN EFFECT FOR ALL FIRE WEATHER DISTRICTS ACROSS THE
AREA WEDNESDAY.  CONDITIONS ARE EXPECTED TO SUBSIDE WEDNESDAY
EVENING AS TEMPERATURES COOL AND RELATIVE HUMIDITIES INCREASE.
