NATIONAL WEATHER SERVICE BILLINGS MT
159 PM MDT MON JUL 23 2001
.TUE AND WED...
AVN SEEMS TO HAVE A BETTER HANDLE ON THE SHORT WAVE GOING INTO WESTERN
MONTANA...KICKING OFF SHOWERS AND THUNDERSTORMS...LOOKING HOW BOTH
MODELS LINED UP WITH THE 18Z WATER VAPOR IMAGERY. DIFFICULT TO TELL ON
THEIR ALIGNMENT WITH THE SURFACE FEATURES AT 18Z. BOTH MODELS BASICALLY
TELL THE SAME STORY...NAMELY THE SLOW EAST PROGRESSION OF THE UPPER
TROUGH. THEY DIFFER IN STRENGTH AND TIMING OF THE SHORT WAVES.
THE MAIN THETA E MAXIMA REMAINS SOUTH OF MONTANA IN WYOMING THROUGHOUT
THE PERIOD. AVN AND ETA DIFFER IN PUSHING UP RIDGES INTO MONTANA...BUT
BOTH SOLUTIONS POINT TO A CONTINUING CHANCE OF THUNDERSTORMS WITH THE
BETTER POSSIBILITIES BEING OVER WYOMING INTO SOUTHEAST MONTANA. CAPES
NOT THAT BAD FOR THE REST OF TODAY...BUT THEY LOOK PROMISING FOR
TUESDAY OVER ABOUT THE EAST HALF OF THE COUNTY WARNING AREA. THEY ALSO
BECOME RATHER HIGH WEDNESDAY OVER EXTREME SOUTHEAST MONTANA AND
SHERIDAN COUNTY. AS THE UPPER TROUGH ADVANCES...MOISTURE BEGINS
DROPPING. IT SEEMS REASONABLE TO LOWER POPS TO ISOLATED ON WEDNESDAY
OVER MOST AREAS...BUT TO KEEP SCATTERED POPS GOING FOR EXTREME SOUTHEAST
MONTANA INTO SHERIDAN COUNTY WYOMING. AM HAVING PROBLEMS WITH AVN ON
WEDNESDAY WITH A VERY STRONG DIVERGENCE PATTERN DEVELOPING OVER ROUGHLY
CENTRAL MONTANA. THIS WOULD AID IN THUNDERSTORM DEVELOPMENT AND THE
SITUATION WILL HAVE TO BE WATCHED. WILL SEE WHAT OTHER MODEL RUNS
INDICATE. CHB
.THU...FRI...SAT...SUN...MON...
AFTER WAVE PASSES WEDNESDAY MORE OF A WESTERLY FLOW BUILDS INTO AREA...
HOWEVER FLOW CONTINUES TO HAVE SOMEWHAT A CYCLONIC FLOW TO IT THURSDAY
AND FRIDAY. WOULD EXPECT A FEW WAVES TO MOVE ACROSS AREA THURSDAY AND
FRIDAY IN THIS FLOW. WESTERLY FLOW...SHOULD...DRY LOWER ATMOSPHERE TO
KEEP CONVECTION THAT DOES OCCUR LESS WIDE SPREAD...BUT ENOUGH TO KEEP
MENTION OF THUNDERSTORMS IN THURSDAY AND FRIDAY. SATURDAY...MODELS BEGIN
TO DIVERGE A BIT. MRF/UKMET DRIVE ENERGY SOUTH FROM GULF OF ALASKA INTO
PACIFIC NORTHWEST WITH DEEPENING SOUTHWEST FLOW OVER MONTANA...THEN
MOVE TROUGH ACROSS AREA...WITH WESTERLY FLOW BY MONDAY. ECMWF MORE
PROGRESSIVE WITH THIS ENERGY SLIDING IT ACROSS MONTANA SATURDAY WITH
RIDGING BY LATE SUNDAY. NEW AVN ON THE OTHER HAND HAS TROUGH MUCH DEEPER
ON WEST COAST THAN 00Z MRF...WHICH COULD OPEN US UP TO DEEPER MOISTURE
AGAIN SATURDAY AND SUNDAY...THUS WILL CONTINUE CHANCE OF THUNDERSTORMS
SATURDAY AND SUNDAY. RASCH
TUE WED THU FRI SAT SUN MON
