.DISCUSSION...HIGH PRESSURE ALOFT OVER SOUTHEAST NEW MEXICO AND A
PACIFIC TROUGH OFF THE PACIFIC NORTHWEST COAST WILL RESULT IN
A STRONG SOUTHWEST FLOW ACROSS THE FIRE SITE BY WEDNESDAY. THE
MOISTURE NEAR THE FIRE SITE WILL SPAWN SHOWERS/THUNDERSTORMS THROUGH
MID-EVENING. ERRATIC WINDS AND LIGHTNING WILL BE THE PRIMARY
CONCERNS TODAY.

THE PACIFIC NORTHWEST TROUGH IS STRONGER THAN IS TYPICAL FOR LATE IN
THE SUMMER. THE ASSOCIATED COLD FRONT WILL REACH NORTHWEST UTAH
LATE WEDNESDAY...AND WILL DRIVE STRONG SOUTHWEST WINDS AT THAT
SITE UNTIL THE FRONT PASSES BY EARLY THURSDAY. ENOUGH MOISTURE
WILL REMAIN OVER THE AREA TO OFFER A THREAT OF SHOWERS/THUNDERSTORMS
ALONG THE COLD FRONT THROUGH WEDNESDAY EVENING. A SOMEWHAT COOLER AND
MUCH DRIER AIR MASS WILL FOLLOW THE FRONT...WITH MOISTURE NOT
RETURNING TO THE AREA UNTIL EARLY NEXT WEEK
