AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ABERDEEN SD 752 PM CDT SAT AUG 2 2008 .UPDATE... VFR LOW CLOUDS ARE EXPECTED TO BREAK UP BEHIND EXITING SHORT WAVE ACROSS NORTHEAST SOUTH DAKOTA AND WEST CENTRAL MINNESOTA THROUGH MIDNIGHT. NEXT SHORT WAVE WILL BE AFFECTING THE REGION AFTER MIDNIGHT INTO SUNDAY MORNING. THE NAM...GFS...AND RUC ALL POINT TO THE CONVECTION IN MT COMING ACROSS THE NORTHERN PART OF THE REGION LATER TONIGHT AND SUNDAY MORNING. THE NAM WAS THE FURTHEREST SOUTH WHERE THE CAP WAS THE STRONGEST. WILL HAVE TO WAIT AND SEE. TOOK OUT POPS FOR THIS EVENING AND MAY HAVE TO ADJUST POPS FOR AFTER MIDNIGHT A LITTLE YET. && .PREV DISCUSSION... .SHORT TERM...TONIGHT THROUGH SUNDAY NIGHT FORECAST CHALLENGES INCLUDE CONVECTION TONIGHT THROUGH SUNDAY NIGHT AND HIGH TEMPERATURES SUNDAY UNDER CLOUD COVER. CURRENTLY...A TROF AXIS SITS ACROSS THE FAR WESTERN FORECAST AREA WITH PLENTY OF LOW LEVEL MOISTURE/INSTABILITY AROUND. THE CAP AT 700HPA IS FORECAST TO UNDERGO CAA THIS EVENING...WITH TEMPS COOLING FROM AROUND +17C TO +13C...WHICH WOULD LIKELY BE ENOUGH COOLING ALOFT TO ALLOW FOR ISOLATED TO WIDELY SCATTERED SUPER CELLULAR THUNDERSTORMS TO DEVELOP WITHIN THE TROF AXIS. THERE IS ALSO 700HPA WARM AIR ADVECTION AND 850HPA MOISTURE ADVECTION ONGOING ACROSS THE EASTERN CWA INTO THIS EVENING. WHEN THE LOW LEVEL JET CATCHES UP TO IT...THE NOSE OF THE LL MAY HELP INDUCE ISOLATED TO WIDELY SCATTERED ELEVATED SUPER CELLULAR THUNDERSTORMS ACROSS THE EASTERN THIRD OF FORECAST ZONES LATE THIS EVENING BEFORE THEY MOVE OFF INTO MINNESOTA. HAVE INSERTED T+RE+ MENTION FOR THESE TO POSSIBLE SCENARIOS AT OPPOSITE ENDS OF THE FORECAST AREA. WILL ALSO HAVE TO KEEP AN EYE ON THE CONVECTION OVER NORTH DAKOTA THAT NOW APPEARS TO BE TRYING TO BUILD SOUTHWARD ALONG THE LEADING EDGE OF 700HPA WAA. LATE TONIGHT ANOTHER MID-LEVEL IMPULSE OF LOW PRESSURE WILL MOVE OUT ONTO THE NORTHERN HIGH PLAINS. LOW LEVEL RESPONSE WILL BE A SURFACE LOW DEEPENING OVER SE MONTANA/NW SOUTH DAKOTA WITH 850HPA MOISTURE ADVECTION AND BACKING LOW LEVEL WINDS POINTING RIGHT INTO EXPECTED THUNDERSTORM CLUSTER THAT WILL BE WORKING WED INTO THE DAKOTAS. EXPECTING THIS STORM CLUSTER TO LATCH ONTO INSTABILITY GRADIENT AT 850HPA OVER THIS CWA AND WHERE THE BEST LOW LEVEL JET SUPPORT SETS UP...RUMBLING EASTWARD OVERNIGHT INTO SUNDAY MORNING. T+RE+ MENTION FOR LATE TONIGHT INSERTED INTO CENTRAL SOUTH DAKOTA ZONES WHERE 20 TO 40 POPS WERE INTRODUCED WITH THIS PACKAGE TO COVER POTENTIAL CONVECTION LATE TONIGHT. ONCE THE MCS DISSIPATES/PUSHES EAST INTO MN...WILL WATCH THE LOW LEVELS RESET ONCE AGAIN WITH LIKELY A REPEAT PERFORMANCE SUNDAY NIGHT INTO MONDAY MORNING. NO SEVERE MENTION AS OF YET...THOUGH...IN THE GRIDS FOR SUNDAY NIGHT. UNDERCUTTING NUMERICAL GUIDANCE HAS BEEN QUITE SUCCESSFUL TODAY. JAMES RIVER VALLEY SOCKED IN WITH STRATUS CLOUDS ALONG THE LEADING EDGE OF 850HPA MOIST TONGUE SLOWLY ADVECTING EAST...AND JUST NEVER FULLY DISSIPATED TODAY. AS SUCH...DID NOT SEE TRUE MAX T POTENTIAL OF MID/UPPER 80S ACHIEVED ACROSS SAID AREA. WITH CONVECTIVE DEBRIS CLOUDS EXPECTED TO BE AROUND DURING THE DAY ON SUNDAY AND SLIGHTLY COOLER 850HPA TEMPS TO MIX OUT ON AN ENE BOUNDARY LAYER WIND...EXPECTING HIGHS ON SUNDAY TO BE AROUND 3 TO 5 DEGREES COOLER THAN TODAY. .LONG TERM...MONDAY THROUGH SATURDAY MODELS CONTINUE IN GOOD AGREEMENT IN OVERALL PATTERN CHANGE FOR THIS WEEK. WITH ZONAL FLOW ACROSS THE CWA TRANSITIONING TO NORTHWEST FLOW AS FAIRLY STRONG TROF DIGS INTO THE EASTERN CONUS...AND WESTERN CONUS RIDGE REESTABLISHES. THIS PATTERN WILL ALLOW FOR COOLER AND DRIER AIR TO FILTER SOUTH OUT OF CANADA AND INTO THE CWA...AND ALLOW FOR NEAR TO BELOW NORMAL TEMPERATURES THROUGH THE LASTER HALF OF THE WORK WEEK. AS FOR PRECIPITATION CHANCES...BEST OPPORTUNITY IS EARLY IN PERIOD WITH ZONAL FLOW ALOFT AND SERIES OF SHORTWAVES SKIRTING THE DAKOTAS. HAVE ADDED ADDITIONAL CHANCE FOR PRECIPITATION IN SOUTH CENTRAL SOUTH DAKOTA AS BACKDOOR FRONT REINFORCES AN EARLIER CANADIAN AIRMASS UNDERGOING MODIFICATION. && .AVIATION... VFR SKIES AND VISIBILITIES ARE EXPECTED TO CONTINUE THROUGH THE NIGHT AND DAY SUNDAY. ANOTHER UPPER LEVEL SHORT WAVE WILL BE AFFECTING THE REGION LATER TONIGHT AND SUNDAY FROM THE WEST. WE MAY SEE SOME TSRAS DEVELOP OUT ACROSS THE WEST AND MOVE ACROSS THE NORTHERN PART OF THE REGION. AT THIS POINT...DONT FORESEE ANY TSRAS OR VICINITY THUNDER OCCURRING AT ANY ONE OF THE TAF STIES. WILL WATCH AND AMEND IF NECESSARY. && .ABR WATCHES/WARNINGS/ADVISORIES... SD...NONE. MN...NONE. && UPDATE...MOHR SHORT TERM...DORN LONG TERM...CONNELLY AVIATION...MOHR WEATHER.GOV/ABERDEEN
