Area forecast discussion, Aug 13, 3:19 PM CDT, 4 hours 55 minutes before
AREA FORECAST DISCUSSION FOR SOUTHEAST SD/SOUTHWEST MN/NORTHWEST IA NATIONAL WEATHER SERVICE SIOUX FALLS SD 319 PM CDT MON AUG 13 2007 .DISCUSSION... TEMPERATURES NOT A WARM AS ANTICIPATED...BUT NOT FOR LACK OF WARM AIR ALOFT. 18Z ABR SOUNDING SHOWED VERY WARM AIR IN THE 800 TO 600 MB LAYER. WARMEST SFC TEMPERATURES WEST OF THE SFC TROF IN CNTRL AND WRN SD WHERE READINGS ARE IN EXCESS OF 105 DEGREES. FARTHER EAST THE STORY IS MORE WITH THE HUMIDITY...DEWPOINTS HAVE RISEN INTO THE MID 70S OVER MUCH OF SE SD AND SW MN...EVEN A DEW 77 DEG READING IN TO NW IA. HIGH DEW POINTS IN COMBINATION WITH TEMPERATURES IN THE UPPER 80S TO MID 90S YIELDING HEAT INDEX VALUES OF 100 TO 105. DESPITE WARM HUMID AIR IN PLACE...THE CHANCES FOR THUNDERSTORMS REMAINS LOW ACROSS THE AREA. STRONG CAP IN PLACE OVER THE ERN CWA DUE TO THE VERY WARM AIR ALOFT...SO NO CHANCE FOR SURFACE BASED CONVECTIVE DEVELOPMENT THIS EVENING. STILL A VERY SMALL CHANCE IN THE WEST ALONG THE SFC TROUGH WHERE HEATING CONTINUES...BUT EVEN HERE THE CAP WILL PROBABLY HOLD. WILL HAVE TO WATCH CONVECTION OVER ERN ND THE REST OF THIS AFTERNOON...AS THERE IS AN OUTSIDE CHANCE STORMS COULD MAKE IT INTO THE MARSHALL MN AREA. MOST LIKE STORMS AND SEVERE WEATHER WILL REMAIN TO THE EAST. LOOK FOR SOME PATCHY FOG TO DEVELOP AFTER MIDNIGHT. TUESDAY SHOULD BE A SEASONAL DAY WITH EASTERLY WINDS...SOME HUMIDITY AND A LESS THAN 20 PERCENT CHANCE FOR PRECIPITATION ALL DAY. GUIDANCE SEEMS IN LINE WITH MID 80S TO LOW 90S. COULD BE SOME PATCHY MORNING FOG OVER THE NORTHERN TWO-THIRDS OF THE CWA...BUT DO NOT EXPECT WIDESPREAD LOW VISIBILITIES. TUESDAY NIGHT POSES A PRETTY DECENT THREAT FOR RAINFALL FOR MANY LOCATIONS. FRONT DROPPING THROUGH TODAY WILL STALL IN CENTRAL NEBRASKA...THEN TRY TO LIFT BACK NORTH ON TUESDAY AFTERNOON AND EVENING. UPPER LEVELS ONLY MARGINALLY SUPPORTIVE...SO DO NOT PLAN ON ANY HIGH END POPS. MAIN CONCERN WILL BE IF THUNDERSTORMS DEVELOP CLOSE TO THE SFC BOUNDARY...WHICH SHOULD BE A LITTLE TOO FAR SOUTH TO GET US RAIN. HOWEVER...BELIEVE SOMETHING CLOSER TO 925MB WILL WORK AND THIS WOULD AT LEAST INCLUDE OUR SOUTHERN THIRD IN DECENT POPS. BY WEDNESDAY AND WEDNESDAY NIGHT...COULD BE A LOT OF CLOUD COVER AND AN OUTSIDE CHANCE FOR PRECIP AS MAIN UPPER LEVEL PUSH COMES THROUGH WEDNESDAY NIGHT...DRIVING COOLER AND DRIER AIR IN FOR THURSDAY. BEST CHANCE SHOULD BE IN THE SOUTHERN HALF OF THE CWA. OTHERWISE...FOR THURSDAY...WENT WITH COOLER THAN NORMAL HIGHS AND PRETTY MUCH DRY FOR ALL LOCATIONS. IN THE LATTER PERIODS(FRI-MON)...THE CONTINUATION OF QUICK WARM UPS AND QUICK COOL DOWNS AS RELATIVELY FAST FLOW CRUISES THE NORTHERN TIER OF THE U.S. FRIDAY NIGHT IN TO SATURDAY STILL LOOKING LIKE THE BEST SHOT FOR PRECIPITATION...BUT FAR FROM PERFECT. WILL CONTINUE MID RANGE POPS DURING THIS TIME. INDICATIONS FROM THE MODELS HOWEVER IS THAT WE WILL TEND TO REMAIN IN A SLIGHTLY COOLER REGIME THAN WE HAVE BEEN IN...WITH A TENDENCY FOR SFC WINDS TO RANGE FROM NORTHEAST TO SOUTHEAST MOST DAYS. WITH THIS TYPE OF FLOW PATTERN...ALSO DIFFICULT TO SUGGEST DRY ON ANY ONE DAY...SO WILL HAVE SOME LOWER END POPS IN MOST PERIODS. DID NOT STRAY SIGNIFICANTLY ON TEMPERATURES OR POPS IN ANY ONE PERIOD. && .AVIATION... VFR SHUD CONT THRU MIDNIGHT...PATCHY MFVR FOG IS LIKELY AT THE TAF SITE AFTER MIDNIGHT...ESPECIALLY ALONG AND SOUTH OF I90. && .FSD WATCHES/WARNINGS/ADVISORIES... SD...NONE. MN...NONE. IA...NONE.
