SPOT FORECAST FOR HORSE
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1057 AM MDT SAT JUL 18 2009

.DISCUSSION...A RIDGE OF HIGH PRESSURE WILL REMAIN IN PLACE
ACROSS THE REGION THROUGHOUT THE WEEKEND...RESULTING IN HOT
DAYTIME TEMPERATURES AND LOW RELATIVE HUMIDITY WITH MARGINAL
OVERNIGHT RECOVERY. WINDS WILL GENERALLY REMAIN LIGHT AND
DRIVEN BY TERRAIN FLOWS...HOWEVER A WEAK DISTURBANCE MOVING
THROUGH THE RIDGE WILL LIKELY SWITCH RIDGELINE WINDS TO THE
WEST SUNDAY AFTERNOON. HIGH BASED MOISTURE IS EXPECTED TO
SLOWLY INCREASE TODAY THROUGH SUNDAY. THIS WILL BRING A SMALL
CHANCE FOR THUNDERSTORMS THIS AFTERNOON NEAR THE BURN
AREA...WITH A BETTER CHANCE SUNDAY AFTERNOON AND EVENING.
GIVEN THE DRY LOW LEVELS IN PLACE...DRY LIGHTNING AND STRONG
WINDS WILL BE POSSIBLE WITH ANY STORMS WHICH DEVELOP...WITH
LITTLE IF ANY PRECIPITATION EXPECTED.
