Area forecast discussion, Jul 3, 3:00 AM CDT, 46 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BISMARCK ND
300 AM CDT TUE JUL 3 2007

.SHORT TERM...TODAY THROUGH THURSDAY NIGHT
PROBLEM FOR TODAY WILL BE TIMING THE THUNDERSTORMS MOVING RAPIDLY
ACROSS WESTERN AND CENTRAL ND THIS MORNING AND WILL WAIT UNTIL LAST
TO MAKE FINAL DECISION.  IN GENERAL...WILL LIKELY REMOVE CHANCE OF
TSTMS FROM THE NW AND POSSIBLY N CENTRAL THIS MORNING...BUT CONTINUE
A SLIGHT CHANCE THIS AFTERNOON. THAT SHOULD BE THE END OF THE TSTM
THREAT FOR REMAINDER OF THE SHORT TERM AS THE UPPER LEVEL RIDGE
AMPLIFIES AND SHIFTS BACK TO THE WEST.

.LONG TERM...FRIDAY THROUGH MONDAY...
THE UPPER LEVEL RIDGE FLATTENS WITH TIME FOLLOWING A PATTERN SIMILAR
TO THE PAST WEEK AND BRINGING YET ANOTHER CHANCE OF TSTMS TO THE
AREA SATURDAY NIGHT AND SUNDAY. MONDAY AND TUESDAY WILL SEE THE
RIDGE REAMPLIFY TO THE WEST AGAIN...SHUTTING DOWN THE POTENTIAL FOR
TSTMS.  TEMPS WILL REMAIN AT OR ABOVE THROUGH THE PERIOD.

&&

.AVIATION...
THUNDERSTORMS WILL MOVE THROUGH SOUTHWEST...CENTRAL...AND EASTERN
NORTH DAKOTA THIS MORNING. CONDITIONS SHOULD IMPROVE THIS
AFTERNOON...ALTHOUGH AFTERNOON HEATING WILL CAUSE SOME INSTABILITY
AND A WEAK POTENTIAL FOR TSTM DEVELOPMENT.

&&

.BIS WATCHES/WARNINGS/ADVISORIES...
NONE.
