AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BISMARCK ND
240 PM CDT SUN AUG 13 2000

12Z ETA RUN WAS OUTSTANDING WITH MORNING CONVECTION DUE WAA AND H5
VORT MAX. WITH THAT ONE WOULD BE INCLINED TO FOLLOW IT ON THE
DETAILS...BUT IF THAT IS DONE ALL POPS WOULD BE DROPPED FROM ZONES
FOR TONIGHT. NGM FOLLOWS THIS PATH AS WELL. THESE MODELS REDEVELOP
DEEP MOIST CONVECTION MONDAY MORNING CENTRAL AND SPREAD IT EAST IN
RESPONSE TO SURFACE TROF AND NEXT VORT MAX PASSING THROUGH. AVN ALSO
DID A RESPECTABLE JOB THIS AM AND IT HAS CONVECTION OVER THE CWA
TONIGHT. BASED ON ALL MODELS HAVING SURFACE FRONT ENTERING STATE
TONIGHT...ALL HAVING SOME LIFT AT H5 AS WELL AS AT H7...AN USTABLE
ATMOSPHERE...AND AT LEAST SOME AVAILABLE POTENTIAL ENERGY...I HAVE
OPTED TO KEEP POPS IN TONIGHT...AND ADD THE CHANCE OF SEVERE. ACTION
SHIFTS EAST AROUND 06Z BEFORE ANOTHER BATCH MOVES OVER CWA IN
RESPONSE TO THAT SECOND MAX I SPOKE OF EARLIER. THIS SHOULD KEEP
SOME CHANCE...LOW...OF STORMS IN CENTRAL ND THROUGH EARLY MORNING
MONDAY...AND UNTIL 18Z IN JMS ZONE. CONCERN MONDAY THEN GOES TO WIND
SPEED IN LINKAGE ALOFT AND TIGHTENING GRADIENT. LATEST RUN INDICATES
HIGHER SPEEDS THAN PREVIOUSLY FORECAST. WILL RAISE SPEEDS BY 5 AND
HOLD OFF ON WINDY WORDING. DRY WEATHER THEN PREVAILS THROUGH
TUESDAY. MRF HOLDS WITH IDEA OF THE NEXT STORM CHANCE COMING TUESDAY
NIGHT OR WEDNESDAY. TEMPS THROUGH PERIOD WILL BE DIFFICULT. CAA
MONDAY WILL ACT TO HOLD TEMPS BACK BUT THIS IS COUNTERED BY A GOOD
DEAL OF SUNSHINE...AT LEAST WEST. NUMERICAL TEMPERATURE GUIDANCE
LOOKS LOW TO ME THROUGH FORECAST PERIOD BASED ON FORECAST HEIGHTS/
THICKNESSES/TEMPS ALOFT. WILL ADJUST UPWARDS.

WILL LOOK FOR A WATCH TO BE ISSUED FOR WESTERN HALF OF CWA PERIOD
