SPOT FORECAST FOR STUMP SPRINGS
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
113 PM MDT THU OCT 29 2009

.DISCUSSION...BROAD UPPER LOW SPINNING OVER THE FOUR CORNERS WILL
CONTINUE TO SLOWLY PROGRESS EASTWARD TODAY THROUGH TONIGHT...BUT
THE REGION WILL REMAIN UNDER DEEP NORTHERLY FLOW THROUGH THAT TIME.
THAT SAID...WINDS ACROSS THE BURN SITE THIS AFTERNOON SHOULD
CONTINUE TO BE DOMINATED BY MEAN FLOW OUT OF THE NORTH TO NORTHEAST
WITH ONLY BRIEF PERIODS OF EASTERLY TO SOUTHEASTERLY DIRECTIONS DURING THE
PEAK HEATING HOURS BETWEEN NOW AND 4PM. PEAK SPEEDS DO NOT APPEAR TO HAVE
BEEN REACHED YET TODAY...WITH GUSTS INTO THE MID 20 MPH LIKELY ALONG THE
UPPER ELEVATIONS OF THE PROPOSED BURN AREA BY MID AFTERNOON. ENHANCED
DRAINAGE COUPLED WITH MEAN FLOW IS EXPECTED TO KEEP NORTHERLY WINDS OF
10 TO 15 MPH THROUGH THE NIGHT TONIGHT.

AN APPROACHING WARM FRONT CURRENTLY OVER CENTRAL NEVADA WILL PASS THROUGH
THE REGION TONIGHT TURNING WINDS MORE NORTHWESTERLY BY DAYBREAK FRIDAY.
STABILITY WILL BE INCREASING SIGNIFICANTLY OVER THE NEXT 24 HOURS...BUT
CLEARING INDICES AT THE ELEVATIONS OF THE SITE STILL LOOK TO REMAIN
ABOVE 500 INTO SUNDAY AT LEAST. HIGH PRESSURE BUILDING IN OVER THE
WEEKEND WILL CONTINUE TO HOLD STRONG THROUGH MID WEEK OF NEXT AT LEAST.
CLEARING INDEX TRENDS SHOULD CONTINUE TO FALL GRADUALLY THROUGH THAT TIME
WITH LITTLE HOPE OF SIGNIFICANT RECOVERY.
