NATIONAL WEATHER SERVICE GREAT FALLS MT
300 PM MDT MON JUL 16 2001

THE PATTERN IS QUITE SIMILAR TO THE PAST FEW DAYS. LOW PRESSURE
CENTERED OVER WA AND BRITISH COLUMBIA...AND A TROF EXTENDING DOWN
ACROSS THE PAC NW.  MOST OF THE INDICES LOOK A LITTLE MORE
THREATENING THAN YESTERDAY...AND CERTAINLY THE WIND SHEAR PATTERN IS
QUITE A BIT BETTER FOR SEVERE WEATHER THAN YESTERDAY. MOST
IMPORTANTLY...A SHORT WAVE PUSHES THRU LATER THIS AFTERNOON AND
EVENING...WITH AN ASSOCIATED SURFACE FRONT. WATCH BOX 559 HAS ALREADY
BEEN ISSUED FOR THE ERN CWA OF MSO AND MOST OF OUR CWA. TUESDAY
ONWARD NOT TOO MUCH CHANGE GOING ON.  SURFACE TEMPS SHOULD TREND A
LITTLE COOLER AS CAA CONTINUES...BUT AT THE SAME TIME THE HEIGHTS
ALOFT WILL BE DROPPING.  THUS AIRMASS REMAINS RELATIVELY UNSETTLED.
ZELZER

EXTENDED...SOME DIFFERENCE AMONG THE MODELS...BUT DO KEEP
UPPER TROUGH OVER PACIFIC NORTHWEST FOR CONTINUED MOIST AND
UNSTABLE SOUTHWEST FLOW FOR DAYS 3 AND 4. UPPER TROUGH THEN
SLITS BY DAY 5 WITH THE NORTHERN BRANCH MOVING THROUGH AREA.
WEAK UPPER RIDGE BUILDS BY DAY 6 AND 7 FOR DRY AND WARMER
WEATHER. TEMPERATURES WILL BE A LITTLE BELOW NORMAL WITH AT
OR A LITTLE ABOVE NORMAL PRECIPITATION.
