FIRE WEATHER PLANNING FORECAST FOR UTAH
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
256 PM MDT THU JUL 24 2008
..A TEMPORARY BREAK IN MONSOON MOISTURE
BROADCAST DISCUSSION
HIGH PRESSURE CENTERED OVER THE SOUTHERN
AND CENTRAL ROCKIES WILL MAINTAIN A WEST-SOUTHWEST FLOW ALOFT
ACROSS THE REGION THROUGH FRIDAY. THE WINDS ALOFT WILL TURN
MORE SOUTHERLY FRIDAY NIGHT...ALLOWING MOISTURE TO RETURN THIS
WEEKEND ACROSS PORTIONS OF CENTRAL AND SOUTHERN UTAH.
DISCUSSION
A MORE WESTERLY FLOW HAS DEVELOPED ACROSS THE
INTERMOUNTAIN REGION WHICH HAS PUSHED THE MAJORITY OF MOISTURE
EAST INTO COLORADO. NOT ALL OF THE MOISTURE HAS BEEN DISPLACED SO
ISOLATED AFTERNOON AND EVENING THUNDERSTORMS ARE STILL POSSIBLE
OVER THE HIGHER TERRAIN OF EASTERN AND SOUTHERN UTAH THROUGH
FRIDAY. THE FLOW ALOFT BECOMES A LITTLE MORE SOUTHERLY FRIDAY
NIGHT THROUGH SATURDAY ALLOWING SOME MOISTURE TO SEEP NORTHWARD
MAINLY AFFECTING SOUTHERN AND EASTERN UTAH BUT COULD SQUIRT FAR
ENOUGH NORTH TO PRESENT A SLIGHT CHANCE OF HIGH BASED
THUNDERSTORMS OVER NORTHERN UTAH ON SUNDAY.
***THUNDERSTORMS IMPLY STRONG GUSTY AND ERRATIC WINDS***
***ALL WINDS ARE 20 FOOT...10-MINUTE AVERAGES***
