Area forecast discussion, Jul 20, 1:55 PM CST, 5 hours 30 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BISMARCK ND 255 PM CDT TUE JUL 20 2004 .SHORT TERM... FORECAST PROBLEM TODAY INCLUDES CONVECTION CHANCES AND PLACEMENT TONIGHT AND POSSIBLE FIRE PROBLEMS ON WEDNESDAY. MODELS IN PRETTY GOOD AGREEMENT IN LARGE SCALE SYNOPTIC PATTERN...AND AS USUAL DIFFERING SOMEWHAT ON STRENGTH OF INDIVIDUAL IMPULSES...PLACEMENT BETWEEN THE ETA AND GFS IS NOT TOO BAD TODAY. CURRENT MSAS DEPICTS SFC TROUGH OVER WESTERN NORTH DAKOTA WITH SFC MOISTURE CONVERGENCE MAINLY FROM BISMARCK AND MINOT EAST TO EAST CENTRAL NORTH DAKOTA. LAPS 18Z SOUNDINGS INDICATE CAPES AOA 2K J/KG OVER CENTRAL NORTH DAKOTA...WITH BIS ALREADY BEYOND CONVECTIVE TEMPERATURE. DIRECTIONAL SHEAR IS PRESENT BUT RATHER WEAK. SPEED SHEAR IS NOT REAL IMPRESSIVE EITHER. SUPERCELL DEVELOPMENT APPEARS MOST LIKELY OVER FAR SOUTHEAST CWA BUT OVERALL CHANCES FOR SUPERCELL DEVELOPMENT NOT GREAT. ALSO WITH WBZ VALUES ABOVE 14K WOULD EXPECT TO HAVE HARD TIME GETTING LARGE HAIL UNLESS WE SEE A SUPERCELL. STILL CANNOT RULE OUT ISOLATED SEVERE CELL ANYWHERE WEST OF A BIS-MOT LINE. WITH SHORTWAVE MOVING INTO EASTERN MONTANA AND RESIDUAL MOISTURE LINGERING BEHIND THE TROUGH IN WESTERN CWA...WILL EXTEND THE CHANCE OF POPS BEYOND 06Z FOR ALL BUT THE NORTHWEST CWA. SUBSIDENCE WILL BE THE DOMINATE FACTOR ON WEDNESDAY BEHIND SFC TROUGH IN NORTHWEST FLOW. SOUTHWEST CWA INDICATES RH VALUES AROUND 30 PERCENT WITH WINDS OF 15 TO 30 MPH. ACCORDING TO RED FLAG DECISION CHART THIS PUTS US IN POSSIBLE CATEGORY FOR RED FLAG WARNING. WILL HOLD OFF ATTM FOR FIRE WX WATCH ISSUANCE BUT LATER SHIFTS WILL HAVE TO MONITOR FOR POSSIBLE LOWER RH VALUES. SECONDARY CDFNT DROPS INTO NRN TIER ZONES LATE WEDNESDAY. SHOWERS CANNOT BE RULED OUT BUT QPF WILL BE MINIMAL SO WILL LEAVE POPS OUT FOR NOW. NORTHWEST FLOW CONTINUES ON THURSDAY WITH ANOTHER POSSIBLE SHOWER CHANCE IN THE AFTERNOON ACROSS THE NORTH AS TQ INDICES RAISE TO 18-20. LOWER ATMOSPHERE IS EVEN DRIER THAN WEDNESDAY HOWEVER SO AGAIN QPF WILL BE MINIMAL. NOT IMPRESSIVE ENOUGH TO INTRODUCE POPS AT THIS TIME. SFC HIGH PRESSURE SETTLES OVER AREA ON FRIDAY FOR ANOTHER DRY DAY. UTILIZED A BLEND OF ETA/GFS GUIDANCE TEMPS THROUGH THE SHORT TERM AS ONLY A FEW DEGREES SEPARATING THEM THROUGHOUT...ALSO VERY CLOSE TO PREVIOUS FCST TEMPS. .LONG TERM... SATURDAY THROUGH TUESDAY...00Z GFS AND ECMWF IN FAIRLY GOOD AGREEMENT. SURFACE HIGH PRESSURE LOOKS TO KEEP THINGS DRY...WITH H500 ENERGY REMAINING NORTH AND SOUTH OF THE STATE. BELOW NORMAL TEMPERATURES AT THE START OF THE LONG TERM...BUILD STEADILY EVERYDAY UNTIL THEY ARE A BIT ABOVE NORMAL BY TUESDAY. THIS REFLECTED WILL IN INHERITED GRIDS AND VERY FEW CHANGES WERE NEEDED OVERALL. && .BIS WATCHES/WARNINGS/ADVISORIES... NONE. && TWH/SHULZ
