AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ABERDEEN SD 345 AM CDT THU JUL 15 2004 .SHORT TERM...TODAY THROUGH 12Z SUNDAY. MAIN CHALLENGE THIS MORNING DEALS WITH PCPN CHCS AND TIMING TODAY. BOTH MODELS SHOW 5H WAVE DROPPING INTO NERN SODAK 12Z THIS MORNING...EXITING THE CWA FAIRLY QUICKLY. MSAS SHOWS COLD FRONT ACROSS NORTHWEST/CENTRAL NODAK WITH OLD BAROCLINIC BOUNDARY DRAPED ACROSS CENTRAL NEB. COLD FRONT FCSTD TO SLIP INTO NERN SODAK BY 18Z AND EXIT BY 00Z FRIDAY. ETA AND GFS SOUNDINGS AT 18Z TODAY ARE STILL SHOWING DECENT INSTAB...WITH CAPES ABOVE 3.1K J/KG. HOWEVER...THIS MUST BE TEMPERED WITH THE FACT THAT LOW LEVEL WINDS ARE NEARLY NON-EXISTANT...WITH FORCING ON 85H AND 7H THETA-E SURFACES DECREASING DURING DAY. ELEVATED CONVECTION IN NODAK THIS MORNING SHOULD CONT DO DECREASE IN INTENSITY AND AREAL COVERAGE AS IT MOVES INTO MORE STABLE ENVIRO...BUT BELIEVE THAT THIS WILL PROVIDE THE FOCUS FOR TSRA LATER THIS AFTN AS COLD FRONT MOVES INTO AREA. BASICALLY TWEAKED TIMING OF PCPN FOR TODAY...BUT GENERAL JIST OF PREV FCST STILL INTACT...WITH CHC POPS STILL WARRANTED. TEMPS STILL APPEAR TO BE WARM AHEAD OF FRONT. NEXT SHOT OF PCPN FOR CWA STILL APPEARS TO BE FRI NIGHT AS SFC LOW DEVELOPS IN SERN MT/ERN WY AND HELPS TO DRAW FRONT BACK TO THE NORTH...ACROSS THE WEST. DONT DOUBT THAT MINOR EMBEDDED WAVES WILL DROP DOWN BACKSIDE OF WRN CONUS RIDGE AIDING IN TSRA DEV...BUT MODELS ARE STILL STRUGGLING TO DISCERN INDIVIDUAL WAVES. OF A BIT OF INTEREST IS THAT THE GFS IS STILL INSISTING ON MCS DEVELOPMENT ACROSS CENTRAL NODAK FRIDAY NIGHT...DROPPING INTO NC/NERN SODAK OVERNIGHT. IT HAS BEEN SHOWING THIS FOR THE PAST COUPLE OF RUNS NOW. ETA/CANADIAN ARE CONSISTENT WITH CANADIAN HIGH PARKING OVER MN DURING THIS TIME...KEEPING FOCUS FOR PCPN FURTHER TO THE WEST. FOR NOW...WILL CONT TO DISCOUNT THE GFS FOR THIS PARTICULAR TIME FRAME...AND STICK WITH ETA/CANADIAN SOLN. THINGS THEN LOOK TO REMAIN CALM THROUGH 12Z SUNDAY. SATURDAY NIGHT WAA AND THETA-E FORCING RETURNS TO CWA AS HIGH MOVES TO THE EAST. NOT MUCH IN THE WAY OF MOIST RETURN SATURDAY NIGHT...BUT WITH MODELS SHOWING 85H JET INCREASING OVERNIGHT COMBINED WITH THETA-E FORCING...CANT QUITE DISCOUNT PSBL CONVECTIVE DEVELOPMENT SATURDAY NIGHT ACROSS CENTRAL SODAK. FOR NOW...WILL KEEP THIS IDEA IN BACK OF MIND AND RE-VISIT DURING LATER MODEL RUNS. .LONG TERM...SUNDAY THROUGH WEDNESDAY PERIOD BEGINS WITH UPPER LEVEL RIDGE STILL POSITIONED ACROSS THE ROCKIES AND A TROUGH ACROSS THE EASTERN US...PRODUCING NW FLOW ALOFT ACROSS THE UPPER MIDWEST. AT THE SURFACE...HIGH PRESSURE SHOULD BE POSITIONED TO OUR EAST WITH SOUTHERLY WINDS INCREASING AHEAD OF LOW PRESSURE. UPPER LEVEL RIDGE AXIS NOW HOLDS BACK TO OUR WEST THROUGH 00Z WEDNESDAY BEFORE TRANSITIONING TO WSW FLOW. COLD FRONT TIMING FOR MONDAY NIGHT INTO TUESDAY MORNING STILL LOOKS GOOD IN GRIDS SO NO CHANGES THERE. A STRONGER COLD FRONT WILL MOVE THROUGH LATE TUESDAY NIGHT INTO WEDNESDAY MORNING. OPTED TO LEAVE PREVIOUS DRY FORECAST ALONE FOR THIS EVENT FOR NOW. ONLY CHANGES TO TEMPS WERE TO RAISE HIGHS FOR SUNDAY AND MONDAY AS RIDGING LOOKS A LITTLE MORE IMPRESSIVE. OVERALL TEMPS SHOULD BE SLIGHTLY ABOVE NORMAL FOR THE FIRST PART OF THE PERIOD THEN COOL ONLY SLIGHTLY TOWARDS THE MIDDLE OF THE WEEK TO NEAR NORMAL TEMPS. && .ABR WATCHES/WARNINGS/ADVISORIES...
