AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SIOUX FALLS SD
1224 PM CDT THU MAY 15 2014

.SHORT TERM...(TODAY AND TONIGHT)
ISSUED AT 356 AM CDT THU MAY 15 2014

TEMPERATURES AND ASSOCIATED FROST POTENTIAL IN COOL AIR MASS ARE THE
PRIMARY FOCUS THROUGH TONIGHT. AS OF 09Z...SEEING TEMPERATURES RANGE
FORM UPPER 20S IN OUR FAR NORTHWEST...TO UPPER 30S IN OUR FAR SOUTH.
CLEAR SKIES AND GENERALLY LIGHT WINDS AT OR BELOW 6KT THROUGHOUT OUR
SD/NE/IA COUNTIES SUPPORT CONTINUING CURRENT FROST/FREEZE HIGHLIGHTS
EARLY THIS MORNING IN THESE AREAS. HOWEVER...INCREASE IN CLOUD COVER
AND A BIT STRONGER WINDS ALONG AND NORTHEAST OF THE BUFFALO RIDGE IN
SOUTHWEST MN ALLOWING TEMPERATURES TO WARM A BIT EARLY THIS MORNING.
WITH THAT...WILL CANCEL HEADLINES IN THAT AREA. THE CLOUD COVER WILL
CONTINUE TO STREAM SOUTHWARD ACROSS AREAS ALONG/EAST OF I-29 THROUGH
THE DAY...WHILE WESTERN AREAS REMAIN MOSTLY SUNNY. EXPECT THE CLOUDS
TO BREAK UP SOME BY MIDDAY...BUT WITH LOW CONVECTIVE TEMPERATURES IN
THE COOL AIR MASS...EXPECT SELF-DESTRUCTIVE SUNSHINE THIS AFTERNOON.
CANNOT COMPLETELY RULE OUT SOME LIGHT SHOWERS/SPRINKLES OVER THE FAR
EAST...AND HAVE ADDED MENTION FOR THE AFTERNOON...THOUGH ANY SHOWERS
SHOULD DIMINISH QUICKLY TOWARD SUNSET. NORTH WINDS ALSO BECOME GUSTY
AGAIN IN THE AFTERNOON...BUT THEY TOO SHOULD DIMINISH QUICKLY IN THE
EVENING WITH APPROACH OF SURFACE RIDGE.

SURFACE RIDGE IS CENTERED OVER THE FORECAST AREA TONIGHT...AND WHILE
925MB TEMPS ARE FORECAST TO BE SLIGHTLY WARMER THAN CURRENTLY...WILL
SEE VIRTUALLY IDEAL RADIATIVE CONDITIONS WITH CLEAR SKIES AND NEARLY
CALM WINDS. THUS WILL MAINTAIN MENTION OF AREAS/WIDESPREAD FROST FOR
THE OVERNIGHT INTO EARLY FRIDAY. OPTED TO HOLD OFF ON ANY ADDITIONAL
HEADLINES GIVEN ONGOING ADVISORY/WARNING IN PLACE...BUT WILL MENTION
IN HWO AND WEATHER STORY EARLY THIS MORNING AND ANTICIPATE HEADLINES
WILL BE HOISTED BY THE DAY SHIFT FOR MUCH OF THE AREA. EXCEPTION MAY
BE IN OUR FAR SOUTHWEST...WHERE AN INCREASE IN CLOUDS SHOULD BE SEEN
LATE TONIGHT.

.LONG TERM...(FRIDAY THROUGH WEDNESDAY)
ISSUED AT 356 AM CDT THU MAY 15 2014

HIGH PRESSURE WILL CONTINUE TO DOMINATE ACROSS THE REGION ON
FRIDAY...AND WILL BANK ON IT BEING DRY WITH OUR AREA WEDGED IN
BETWEEN SYSTEMS JUST TO THE WEST AND EAST OF OUR CWA. THERMAL
PROFILES WILL MODERATE JUST A BIT OVER TODAY...AND LOOKING AT HIGHS
IN THE MID 50 TO LOWER 60S. WINDS WILL DROP OFF ONCE AGAIN ON FRIDAY
NIGHT...THOUGH WITH THE MODERATION IN THERMAL PROFILES...DO NOT
ANTICIPATE A FROST THREAT WITH LOWS REMAINING IN THE MID AND UPPER
30S.

THE HIGH PRESSURE WILL CONTINUE TO DOMINATE ON SATURDAY...THOUGH
WITH A SOUTHERLY FLOW INCREASING AS THE HIGH NUDGES OFF TO THE
EAST...IT WILL BE AN EVEN MILDER DAY WITH HIGHS INTO THE MID AND
UPPER 60S. BY SUNDAY...A WEAK SHORTWAVE TRACKS OUT OF THE NORTHERN
ROCKIES...WITH INCREASING THETA E ADVECTION IN OUR WEST AS LOW LEVEL
JET DEVELOPS THROUGH WESTERN AND CENTRAL SOUTH DAKOTA. THE BETTER
INSTABILITY REMAINS OFF TO OUR WEST...AND MOISTURE IS NOT OVERLY
IMPRESSIVE...BUT CANNOT NOT RULE OUT AN ISOLATED SHOWER THROUGH OUR
SOUTH CENTRAL SOUTH DAKOTA/MISSOURI RIVER CORRIDOR ZONES. HIGHS LOOK
TO NUDGE UP JUST A LITTLE MORE...INTO THE UPPER 60S TO LOWER 70S.

BY THE BEGINNING OF NEXT WEEK...UPPER LEVEL RIDGING BUILDS INTO THE
REGION...THOUGH PRECIPITATION CHANCES WILL BE BETTER THROUGH MIDWEEK
WITH INCREASING INSTABILITY/MOISTURE INTO THE REGION AS THE LOWER
LEVEL FLOW TAPS INTO GULF OF MEXICO MOISTURE. STILL NOT OVERLY WARM
HOWEVER WITH HIGHS MID 60S TO MID 70S...WITH LOWS IN THE 50S.
