Area forecast discussion, Jun 22, 12:30 PM MDT, 8 hours 36 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BISMARCK ND 130 PM CDT SAT JUN 22 2002 500 MB PROG INDICATES THAT MID/UPPER LEVEL LOW WILL SLOWLY MOVE FROM UTAH TO NE NORTH DAKOTA BY MONDAY AFTERNOON. THE APPROACH AND PASSAGE OF THIS FEATURE WILL BRING LARGE SCALE ASCENT TO A MOIST AND UNSTABLE ATMOSPHERE FOR THE NEXT 48 HOURS. THIS EVENING WILL BRING A H5 VORT MAX INTO THE WEST...WITH A WARM FRONT IN NORTHERN SOUTH DAKOTA. PROG SOUNDINGS INDICATE SOME CAPPING ABOVE THE WARM FRONTAL INVERSION EARLY TODAY AND LATE TONIGHT...WITH A WINDOW OF OPPORTUNITY FOR CONVECTION AROUND 00Z. THUS IT LOOKS LIKE A REPEAT OF LAST NIGHT. AGAIN THE NORTHERN HALF OF THE STATE WILL STAND THE BETTER CHANCE OF ACTIVITY BECAUSE OF THE CAPPING. I WILL GO WITH HIGH POPS...A CHANCE OF SEVERE...AND BECAUSE OF THE WARM FRONTAL POSITION I WILL ADD MENTION OF HEAVY RAIN. ISENTROPIC ANALYSIS INDICATES THE BIG NORTHWARD LIFT WILL OCCUR AFTER 9 PM CDT TONIGHT...SO THE SPC FORECAST OF A LATE NIGHT MCS LOOKS GOOD. SUNDAY EVENING AND NIGHT WILL BRING SOME SURFACE CONVERGENCE AS AN INVERTED TROUGH SLIDES ACROSS THE WEST AND CENTRAL PORTIONS OF THE STATE...WITH THE UPPER LEVEL SYSTEM DIRECTLY OVER THE STATE. SO IT LOOKS LIKE ANOTHER ROUND OF THUNDERSTORMS. MONDAY WILL BRING IMPROVING WEATHER WITH THE APPROACH OF A MID LEVEL H5 RIDGE. .BIS...NONE. RSL
