AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ABERDEEN SD 350 PM CDT SAT JUL 16 2005 .SHORT TERM...TONIGHT THROUGH TUESDAY. MAIN FORECAST CHALLENGE IS PRECIP CHANCES FOR TONIGHT AND TOMORROW. WATER VAPOR IMAGERY CURRENTLY SHOWING LOCATION OF IMPRESSIVE SUMMER LOW FEATURE ROTATING ACROSS SOUTHERN SASKATCHEWAN. A LEADING SHORT WAVE AROUND THIS LOW IS RESPONSIBLE FOR THE ONGOING CONVECTION PUSHING NORTHEASTWARD ACROSS CENTRAL NORTH DAKOTA AT THIS TIME. MEANWHILE...ABR CWA REMAINS UNDER STRONG CAP WITH H7 TEMPERATURES REACHING FROM +12 TO +16C E/W AND WARM FRONT NOW STRETCHED JUST NORTH OF CWA. ASSOCIATED LOW PRESSURE CENTER IS LOCATED IN SOUTHEASTERN MONTANA AS ANALYZED ON 18Z SUBJECTIVE MSAS ANALYSIS. THIS LOW CENTER WILL ELONGATE AS IT ENTERS THE DAKOTAS UNDER THE INFLUENCE OF MAIN UPPER TROUGH AROUND THE LOW. THIS RESULTS IN A DISTINCT COLD FRONTAL BOUNDARY WITH DECENT LOW LEVEL CONVERGENCE. ALTHOUGH TEMPERATURES REMAIN WARM ALOFT...SOME CONVECTION HAS DEVELOPED ALONG THIS CONVERGENCE ZONE INTO NORTHWESTERN SOUTH DAKOTA. DID INTRODUCE CHC AND ISOLATED POPS IN NW COUNTIES...HOWEVER SUPPORT FOR CONVECTION INTO FORECAST AREA APPEARS TO DIMINISH INTO THE NIGHT WITH EXISTING THERMAL CAP AND LOSS OF SURFACE FORCING. SPC DID ISSUE SEVERE WATCH FOR THREE OF NORTHWEST COUNTIES AS WELL UNTIL 04Z WITH STEEP LAPSE RATES AND LARGE AMOUNT OF INSTABILITY PRESENT AHEAD OF SURFACE BOUNDARY. THUNDERSTORM DEVELOPMENT MAY BE POSSIBLE SUNDAY MIDDAY ALONG THE FRONT AS IT CROSSES EASTERN ZONES. INSTABILITY REMAINS SUFFICIENT WITH NAM SOUNDINGS INDICATING NEAR 3000 J/KG SBCAPE AHEAD OF FRONTAL BOUNDARY. CAP ALSO BEGINS TO WEAKEN RAPIDLY WITH PERSISTENT CAA IN NORTHWESTERLY FLOW. HOWEVER...NAM AND GFS NOW INDICATING A FASTER PROGRESSION OF THE COLD FRONT AND HAVE IT EXITING CWA BY MID AFTERNOON. THIS MAY NOT ALLOW ENOUGH TIME FOR SURFACE CONVERGENCE AND DAYTIME HEATING TO BREAK THE STRONG CAP. THEREFORE...LEFT ONLY A SLIGHT CHANCE FOR THUNDERSTORMS IN THE EASTERN ZONES FOR TOMORROW. BEHIND THE FRONT...NORTHWESTERLY WINDS WILL PICK UP AS NEAR 10MB PRESSURE GRADIENT DEVELOPS ACROSS CWA. WINDS SHOULD STAY UNDER ADVISORY CRITERIA AS H925 WINDS PICK UP ONLY BRIEFLY TO 30-35KT BEHIND COLD FRONT. HIGH PRESSURE THEN MOVES IN FOR MONDAY AND COOLER CONDITIONS ARE EXPECTED WITH H85 TEMPS FALLING TO +10 TO +14C. RETURN FLOW STARTS AGAIN ON TUESDAY IN RESPONSE TO NEXT SOUTHERN CANADIAN TROUGH. .LONG TERM...WEDNESDAY THROUGH SATURDAY WITH THE EXCEPTION OF THE GFS MODEL...WHICH HAS BEEN RATHER INCONSISTENT WITH FEATURES THE LAST COUPLE OF DAYS...MEDIUM RANGE SOLUTIONS APPEAR TO HAVE A HANDLE ON THE WEATHER PATTERN IN THE OUT PERIODS. WEDNESDAY OPENS WITH AN UPPER LEVEL WAVE TRAVELING THROUGH SOUTHERN CANADA...DRAGGING A COLD FRONT THROUGH THIS AREA. LEFT THIS PERIOD DRY THOUGH AS 700HPA TEMPS TOO WARM TO SUPPORT CONVECTION. MOSTLY ZONAL FLOW OVER THIS AREA WITH A FEW WEAK SHORT WAVES SKIRTING THE NORTHERN PLAINS THURSDAY THROUGH SATURDAY. WEDNESDAY FRONTAL BOUNDARY RETURNS TO CWA AS A WARM FRONT LATE THURSDAY NIGHT INTO FRIDAY...BUT AGAIN...BY THE TIME FRONTAL BOUNDARY REACHES CWA...MID-LEVEL THERMAL PROGS ARE WARM ENOUGH TO CAP THE ATMOSPHERE AND KEEP CONVECTION FROM DEVELOPING. COOLING TREND IN PLACE FOR WEDNESDAY AND THURSDAY AS HIGH PRESSURE DOMINATES THE CWA THOSE TWO DAYS. THEN...WAA ENSUES IN RETURN FLOW SET-UP FRIDAY AND SATURDAY. && .ABR WATCHES/WARNINGS/ADVISORIES... SD...NONE. MN...NONE. && LILES/DORN
