SPOT FORECAST FOR WILDFIRE INVESTIGATION TRAINING
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
944 AM MDT TUE APR 30 2013

.DISCUSSION...A COLD FRONT IS STALLED ACROSS CENTRAL UTAH THIS
MORNING...AND SHOULD REMAIN NORTH OF THE TRAINING SITE THROUGH
THE DAYLIGHT HOURS. THIS SHOULD ALLOW GUSTY SOUTHWESTERLY WINDS
TO DEVELOP LATE IN THE MORNING...WITH A CHANCE THAT WINDS REMAIN
LIGHT AND VARIABLE OR LIGHT NORTHWESTERLY UNTIL EARLY AFTERNOON.
THROUGH THE AFTERNOON...THE TRAINING SITE WILL LIKELY DEVELOP
THESE SOUTHWESTERLY WINDS WITH LESS STRENGTH THAN MORE EXPOSED
AREAS CLOSER TO ST. GEORGE AND THE ARIZONA BORDER.

THE COLD FRONT WILL FINALLY PUSH THROUGH THE AREA
OVERNIGHT...LIKELY AROUND MIDNIGHT. THIS WILL LIKELY TRANSLATE TO
A NORTHERLY OR NORTHWESTERLY WINDS AT THE TRAINING SITE...WHICH
SHOULD PERSIST THROUGH THE DAY WEDNESDAY TO GO ALONG WITH
CONSIDERABLY COOLER TEMPERATURES. THURSDAY WILL REMAIN VERY DRY
WITH WARMING TEMPERATURES. THERE IS A SLIGHT CHANCE THAT CLEARING
COULD BE MARGINAL ON THURSDAY AS HIGH PRESSURE BUILDS...BUT THE
MORE LIKELY SCENARIO RIGHT NOW LOOKS TO BE CLEARING INDICES ABOVE
500 AND NORTHEASTERLY SURFACE WINDS OF 5 T0 10 MPH THROUGH MUCH
OF THE DAY.
