.DISCUSSION...AS THE RIDGE OF HIGH PRESSURE MOVES OFF TO THE EAST AND
A PACIFIC TROUGH TRACKS EAST ALONG THE CANADIAN BORDER...THE PRESSURE GRADIENT
WILL INCREASE AND SOME INCREASE IN WIND SPEED IS ANTICIPATED FRIDAY.
THE CHANCES OF PRECIPITATION WILL GRADUALLY INCREASE THROUGH EARLY NEXT WEEK
AS A LOW PRESSURE SYSTEM FROM THE SOUTHWEST UNITED STATES INFLUENCES OUR
WEATHER AND A NORTHERN STREAM CANADIAN TROUGH APPROACHES THE NORTHERN ROCKIES
FROM THE NORTH. HOWEVER...THE SPLITTING NATURE OF THIS FLOW PATTERN OVER
WYOMING WILL LOWER THE CHANCES OF A SIGNIFICANT PRECIPITATION EVENT. THE
TEMPERATURES WILL BECOME COOLER DURING THE WEEKEND.

...THUNDERSTORMS IMPLY STRONG GUSTY AND ERRATIC WINDS...
