Area forecast discussion, Aug 7, 3:15 PM CDT, 4 hours 28 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BISMARCK ND 315 PM CDT MON AUG 7 2000 SURFACE FRONT NOW ON THE MT/ND BORDER WITH A 10 DEGREE DROP IN DEW POINTS WITH IT. WIDELY SCATTERED SHOWERS INCREASING OVER SOUTHWEST ND BUT LIGHTNING STRIKES ARE LACKING. ETA IS SLOWER OF MODELS...THOUGH ALL ARE IN RELATIVE AGREEMENT. BETTER DEVELOPMENT IS IN WESTERN SD AND THIS IS INTERESTING BASED ON LATEST MESO-ETA WHICH SHOWS SPLIT ENERGY BUT INTENSIFIES THE SOUTHERN MAX...OVER SD. THIS WOULD SPREAD THE STRONGEST STORMS OVER THAT STATE AND POSSIBLY INTO SOUTH CENTRAL ND IN STRONG NORTHERN LOBE. THE ETA HAS TWO SIMILAR SYSTEMS WITH THE NORTH ONE SLIGHTLY STRONGER...INDICATING A BETTER CHANCE NORTH. THERE IS AMPLE CAPE AND INSTABILITY PRESENT...AND WITH SPC HAVING CWA IN SLGT RISK WILL WORD ZONES POSSIBLE SEVERE. ALL MODELS CUT THE STORMS OFF BY MIDNIGHT FROM MOT-BIS. WITH THAT IN MIND WILL DETAIL ENDING TIME FOR STORMS AS THIS EVENING WEST AND BY MIDNIGHT CENTRAL. THE DRIER AIR COVERS ALL OF CWA BY MID DAY TUESDAY AND WITH CONVECTIVE TEMPS ABOUT 5 DEGREES OVER FORECAST HIGHS WILL WORD MOSTLY SUNNY. THE H5 RIDGE FLATTENS BUT WITH NEARLY FULL SUNSHINE WEDNESDAY...AND CONVECTIVE TEMPS NEARLY 10 DEGREES OVER FORECAST HIGHS...TEMPS WILL STILL BE 80 TO 85 FOR HIGHS...AND WILL WORD SUNNY. DRY WEATHER CONTINUES FOR MUCH OF THE WEEK WITH A BUILDING H5 RIDGE AGAIN BY THURSDAY. BY THE WEEKEND THE RIDnGE IS SO AMPLIFIED THAT IT ALLOWS ENERGY IN TO THE BACK SIDE FOR A CHANCE OF STORMS. .BIS...NONE. JP MARTIN
