SPOT FORECAST FOR LAKE FORK
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1101 AM MDT SUN JUL 26 2009

.DISCUSSION...WEATHER PATTERN IS GOING THROUGH A TRANSITION TODAY
THROUGH MONDAY. INSTEAD OF THE RIDGE OVER THE FOUR CORNERS REGION
CONTROLLING OUR WEATHER A MAJOR TROUGH DEVELOPING OVER THE HIGH
PLAINS WILL IMPACT US FOR MOST OF THIS COMING WEEK. THE WINDS
ALOFT WHICH HAVE BEEN SOUTHERLY AND IMPORTED DEEP MOISTURE ACROSS
UTAH THE PAST SEVERAL DAYS HAVE SHIFTED TO WESTERLY TODAY AND WILL
TRANSITION TO NORTHWEST THIS AFTERNOON AND REMAIN NORTHWEST THROUGH
THE WEEK. THIS MEANS DRIER AND SLIGHTLY COOLER CONDITIONS ARE
COMING. MEANWHILE...LAKE FORK IS UNDER THE NORTHERN PORTION OF THE CONVERGENT
AREA BETWEEN THE MOIST AIR MASS AND THE DRIER AIR MASS TRYING TO
MOVE IN FROM THE NORTHWEST. THIS CONVERGENT AREA SHOULD REMAIN
OVER YOUR AREA THROUGH EARLY AFTERNOON AND THEN MOVE SOUTH OF THE
FIRE THIS AFTERNOON. THEREFORE THE BEST CHANCE OF SHOWERS AND THUNDERSTORMS
WILL BE MID AFTERNOON WITH PERHAPS ONLY AN ISOLATED THUNDERSTORM
REMAINING INTO THIS EVENING. ANY SHOWERS AND THUNDERSTORMS THAT
FORM THIS AFTERNOON WILL MOVE FROM NORTHWEST TO SOUTHEAST.
