SPOT FORECAST FOR DUCK CREEK
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
607 AM MDT THU OCT 21 2010

.DISCUSSION...THE UPPER LEVEL LOW PRESSURE SYSTEM ACROSS SOUTHWEST
ARIZONA THIS MORNING WILL TRACK EAST INTO WESTERN NEW MEXICO BY
THIS EVENING. MOISTURE WRAPPING AROUND THE LOW PRESSURE WILL
MAINTAIN SHOWERS AND A FEW THUNDERSTORMS ACROSS SOUTHERN UTAH TODAY.
MOST OF THE SHOWER/THUNDERSTORM ACTIVITY WILL BE LATER THIS
AFTERNOON AFTER A LULL IN THE ACTIVITY THIS MORNING. CLEARING
INDICES WILL BE LOWER MUCH OF TODAY DUE TO LESS PRECIPITATION AND
LIGHT TRANSPORT WINDS.

A WEAK WEATHER DISTURBANCE WILL CROSS WESTERN UTAH FRIDAY. THIS
DISTURBANCE WILL BRING A MODEST INCREASE IN TRANSPORT WINDS...BUT
ONLY A MINIMAL THREAT FOR ADDITIONAL PRECIPITATION. WINDS WILL
INCREASE OVER THE WEEKEND AS A SERIES OF WEATHER DISTURBANCES RACE
EAST ACROSS NORTHERN UTAH. NOT LOOKING AT ANY SUBSTANTIAL THREAT FOR
PRECIPITATION FROM THESE PASSING DISTURBANCES UNTIL SUNDAY AT THE
SOONEST. COOLER TEMPERATURES AND A BETTER CHANCE OF SNOW WILL EXIST
DURING THE EARLY TO MIDDLE PORTION OF NEXT WEEK.
