SPOT FORECAST FOR BRIGHTON PILE RX
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
551 PM MDT MON JUN 21 2010

.DISCUSSION...A WEAK WEATHER SYSTEM WILL MOVE THROUGH NORTHERN
UTAH DURING THE DAY TUESDAY. THIS SYSTEM IS NOW FORECAST TO BE
A BIT BETTER ORGANIZED AND SHOULD HAVE ENOUGH MOISTURE TO BRING
ISOLATED SHOWERS AND THUNDERSTORMS TO THE AREA TUESDAY AFTERNOON
AND EVENING...ALTHOUGH THE GREATEST THREAT FOR STORMS SHOULD
REMAIN EASTWARD ACROSS THE UINTAS. AS THIS SYSTEM MOVES THROUGH
THE AREA WEST-NORTHWEST WINDS ALOFT SHOULD SERVE TO ENHANCE
AFTERNOON UPSLOPE WINDS AT THE SITE.

IN THE WAKE OF THIS SYSTEM HIGH PRESSURE AND LIGHT FLOW ALOFT
WILL DEVELOP ACROSS THE AREA ON WEDNESDAY ALONG WITH AN
ACCOMPANYING DRYING TREND. THIS WILL ALSO LIMIT VENTILATION
SOMEWHAT GIVEN THE WEAKER FLOW ALOFT...HOWEVER CLEARING INDICES
SHOULD EXCEED 500 DURING THE AFTERNOON. BY THURSDAY
SOUTHWESTERLY FLOW ALOFT IS EXPECTED TO REDEVELOP ALLOWING FOR
WARMER TEMPERATURES AND CONTINUED DRYING.
