AREA FORECAST DISCUSSION FOR SOUTHEAST SD/SOUTHWEST MN/NORTHWEST IA
NATIONAL WEATHER SERVICE SIOUX FALLS SD
315 AM CDT THU JUL 14 2011

.DISCUSSION...
SHORT WAVE MOVING THROUGH EASTERN SD AS OF 08Z WILL CONTINUE TO MOVE
EAST OUT OF CWA. SCATTERED THUNDERSTORMS ASSOCIATED WITH THIS
FEATURE WILL GENLERALLY BE EAST OF I29 BY 12Z AND WILL KEEP CHANCE
IN THAT AREA THROUGH MID MORNING.

THE OTHER ISSUE FOR TODAY IS THE WIDESPREAD STRATUS THAT IS
DEVELOPING BEHIND THIS WAVE AS LOW LEVEL MOISTURE STREAMS NORTH
UNDER INVERSION WEST OF WAVE. EXPECT EXTENSIVE CLOUD COVER MOST OF
THE DAY ACROSS THE EAST WITH CLOUDS BREAKING UP IN THE AFTERNOON
ACROSS THE WEST. THIS WILL HAVE AN IMPACT ON TEMPERATURES ACROSS THE
CWA AND DID LOWER A FEW DEGREES.

CAP BEGINS TO BUILD ACROSS CWA TONIGHT...AND IF WE CANT GET RID OF
STRATUS...IT MAY REMAIN IN PLACE ALL NIGHT AND INTO PART FRIDAY.
SOMETHING TO WATCH AS AGAIN THIS COULD HAVE AN EFFECT ON HIGHS
ACROSS TH EAST.

WAEK WAVE MOVES ACROSS NORTHERN AND WESTERN FRINGE OF CWA LATE THIS
AFTERNOON AND TONIGHT AND COULD SEE A FEW STORMS DEVELOP ON EDEGE OF
CAP MAINLY ALONG AND NORTH OF I90. SO WILL KEEP SMALL POPS IN. IF
STORMS CAN DEVELOP...THEY COULD BECOME SEVERE ACROSS THE WEST LATE
AFTERNOON OR EVENING WITH WIND THE MAIN THREAT. THE RAIN CHANCE IS
VERY CONDITIONAL ON WHETHER CAP CAN BREAK.

SURFACE FRONT WILL REMAIN LOCATED ACROSS NORTHERN CWA ON EDGE OF CAP
SATURDAY...AND WITH HEATING DURING THE DAY...MAY BE ENOUGH TO BREAK
CAP A BRING A CHANCE OF STORMS TO CWA MAINLY DURING THE NIGHT...WITH
BEST CHANCE NORTH OF I90. AFTER THAT...RIDGE ALOFT BUILDS EVEN MORE
WITH THREAT OF STORMS THEN SHIFTING OUT OF CWA SUNDAY INTO NEXT
WEEK.

HIGH TEMPERATURES ON FRIDAY WILL PROBABLY NOT MIX OUT AS WARM AS
FORECAST ESPECIALLY WITH SUCH HIGH DEWPOINTS...BUT STILL VERY WARM
AND HUMID WITH HIGHS IN THE UPPER 80S TO LOWER 90S. THE TEMPERATURES
AND DEWPOINTS WILL PUSH HEAT INDICES NEAR ADVISORY LEVEL FRIDAY
AFTERNOON ACROSS THE SOUTH...WITH HEAT ADVISORY CRITERIA BEING MET
ACROSS ALL OF THE CWA SATURDAY THROUGH AT LEAST TUESDAY OR WEDNESDAY
OF NEXT WEEK. LOOKS LIKE ONE OF THE HOTTER STRETCH OF DAYS IN THE
LAST FEW YEARS. EVEN BEYOND EARLY NEXT WEEK...IT MAY REMAIN HOT AND
HUMID AT LEAST THROUGH NEXT WEEKEND IF GFS IS CORRECT.
HOWEVER...ECMWF IS SHOWING THE RIDGE BREAKING DOWN BY NEXT WEEKEND
WITH SUBSTANTIALLY COOLER TEMPERATURES. BUT AT LEAST THROUGH
WEDNESDAY IT LOOKS HOT ON ALL THE MODELS.

FINALLY...DEWPOINTS WILL REALLY INCREASE TODAY AND WILL GENERALLY BE
IN THE 70S ACROSS THE CWA BY MID TO LATE AFTERNOON AND PERSIST
THROUGH AT LEAST MID WEEK. SO THIS WILL MAKE THE HEAT DANGEROUS.

&&

.AVIATION...
EARLY MORNING CONVECTION EXPECTED TO TRACK TO THE NORTH AND
EAST...AND DIMINISH ACROSS THE AREA BY 15Z. MORNING MVFR
CEILINGS...TO LOCALIZED IFR CEILINGS...WILL IMPROVE INTO THE VFR
RANGE BY 18Z.

&&

.FSD WATCHES/WARNINGS/ADVISORIES...
SD...NONE.
MN...NONE.
IA...NONE.
NE...NONE.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY

REGION. IF THESE STORMS CAN DEVELOP...A FEW MAY BECOME SEVERE.

DANGEROUS HEAT INDICES OF 100 TO 105 DEGREES CAN BE EXPECTED
FRIDAY AFTERNOON AND EVENING...AND IN THE 100 TO 110 DEGREE RANGE
SATURDAY AFTERNOON AND EVENING.

DANGEROUS HEAT INDICES OF 105 TO 110 DEGREES WILL PERSIST DURING
THE AFTERNOON AND EVENING HOURS SUNDAY THROUGH WEDNESDAY.
