SPOT FORECAST FOR COVE MTN TIMBER PILES
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
814 AM MDT THU APR 25 2013

.DISCUSSION...INSTABILITY AIDED BY AN UPPER LOW MOVING INTO
ARIZONA WILL ALLOW FOR EXCELLENT CLEARING THIS AFTERNOON AT THE
COVE MTN SITE. LIGHT SLOPE FLOWS ARE EXPECTED TO BECOME MORE
WEST/SOUTHWEST TODAY WITH SPEEDS GENERALLY IN THE 10 MPH RANGE.
THIS SAID...CAN NOT RULE OUT AFTERNOON CONVECTION/BUILDUPS OVER
NEIGHBORING TERRAIN AND A BRIEF AND GUSTY SHOWER/STORM AFTER
1400. WETTING RAINS ARE NOT EXPECTED HOWEVER. AS THE LOW SHIFTS
EAST TOMORROW STABILITY WILL INCREASE BUT COMBINATION OF MARGINAL
TRANSPORT WINDS AND LOW LEVEL INSTABILITY WILL ALLOW FOR GOOD
CLEARING ONCE AGAIN.

WEAK HIGH PRESSURE BUILDING INTO THE AREA WILL FURTHER INCREASE
STABILITY SATURDAY AND TRANSPORT WINDS WILL BE NEAR NIL. AS
A RESULT CLEARING NOW LOOKS TO BE POOR ATTM. INCREASED
SOUTHWESTERLY FLOW ALOFT ON SUNDAY INTO MONDAY LOOKS TO ALLOW
FOR GOOD TO EXCELLENT CLEARING HOWEVER.
