Area forecast discussion, Jul 19, 1:59 PM CDT, 6 hours 47 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BISMARCK ND 159 PM CDT TUE JUL 19 2005 .SHORT TERM...TONIGHT THROUGH FRIDAY NIGHT THE MODELS ARE IN FAIRLY GOOD AGREEMENT THROUGH FRIDAY NIGHT. CURRENTLY A COLD FRONT IS WORKING ITS WAY ACROSS THE STATE. AT 17Z IT WAS ROUGHLY ALONG A LINE FROM MINOT TO DICKINSON...AND SHOULD MOVE EAST ABOUT 100 MI BY 20Z. THE NAM WEAKENS THE CAP THIS AFTERNOON ALONG THE FRONT AND WITH A WEAK SHORT WAVE MOVING ACROSS THE STATE AT THE SAME TIME...COULD SEE CONVECTION DEVELOP. WILL BE A QUESTION OF TIMING FOR BISMARCK AND MINOT...AS THE RUC AND NAM DIFFER ON THE SOUNDINGS...WITH THE NAM MUCH MORE DYNAMIC. CONSEQUENTLY...WILL LIMIT THE CHANCE OF TSTMS TO CENTRAL AND EASTERN COUNTIES...WITH THE BEST CHANCE IN THE EAST. THE NEXT CHANCE OF TSTMS WILL BE ON THURSDAY AS A SHORT WAVE MOVES ACROSS THE AREA ALONG WITH AN ASSOCIATED WEAK SURFACE LOW. TIMING WOULD PUT THE LOW IN CENTRAL ND AT 18Z. SPEED OF THE LOW WILL MAKE FOR A SORT LIVED EVENT AND LOOKS LIKE MAIN CHANCE OF AFTN/EVE TSTMS WILL BE IN SOUTHEAST COUNTIES. ANOTHER UPPER LEVEL SHORT WAVE/SURFACE LOW COMBINATION WILL MOVE ACROSS THE STATE LATE FRIDAY AND FRIDAY NIGHT AND APPEARS TO BE A LITTLE STRONGER WITH BETTER DYNAMICS. .LONG TERM...SATURDAY THROUGH TUESDAY NIGHT. LITTLE CHANGES ONLY FOR THE EXTENDED FORECAST PACKAGE. LARGE AREA OF UPPER LEVEL HIGH PRESSURE REMAINS OVER THE CENTRAL UNITED STATES. THE NORTHERN PLAINS REMAINS UNDER MOSTLY ZONAL FLOW BEFORE GRADUALLY TRANSITIONING TO A MORE NORTHWESTERLY FLOW ALOFT BY THE MIDDLE OF NEXT WEEK. A FEW WEAK FRONTAL BOUNDARIES LOOK TO MOVE THROUGH THE AREA...BUT THESE FEATURES ARE DIFFICULT TO TIME SO LEFT POP AND WEATHER GRIDS VIRTUALLY UNTOUCHED BESIDES SOME MINOR COSMETIC EDITS. && .BIS WATCHES/WARNINGS/ADVISORIES... && TSW/NH
