Area forecast discussion, Jul 6, 2:15 PM MST, 5 hours 45 minutes before
UTAH AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
315 PM MDT FRI JUL 6 2001

SYNOPSIS...A MOIST AND UNSTABLE AIRMASS WILL BRING SHOWERS
AND THUNDERSTORMS TO MUCH OF UTAH THROUGH SUNDAY.

DISCUSSION...DEEPEST MOISTURE HAS STAYED OVER ABOUT THE WESTERN 1/3
OF THE FORECAST AREA. CONVECTION SO FAR HAS BEEN VERY SHORT PULSE
ALTHO SOME OF THE CELLS APPEAR TO BE TRAINING. THE SHORT WAVE OVER
AZ SHOULD BE LIFTING INTO UTAH TONIGHT AND ACTIVITY SHOULD CONTINUE
MUCH OF THE NIGHT AS THIS MOVES NORTH. VERY HEAVY RAINS HAVE BEEN
NOTED TO OUR SOUTH IN THE DEEPER MOISTURE CLOSER TO THE WAVE.
EXPECT THESE TO SPREAD INTO SOUTHERN UTAH THIS EVENING AND WILL
ISSUE A FLASH FLOOD WATCH FOR OUR SOUTHWESTERN 4 COUNTIES UNTIL
MIDNIGHT.

THIS WAVE SHOULD BRING FAIRLY WIDESPREAD PRECIP TO MOST OF THE
FORECAST AREA, ALTHO THE CONSIDERABLE CLOUDINESS ACCOMPANYING THIS
FEATURE COULD HOLD BACK CONVECTIVE DEVELOPMENT SOMEWHAT.

MODELS ALSO DISTINGUISH BETWEEN THIS SHORT WAVE AND THE CIRCULATION
MOVING INTO SRN CA. THIS SECOND FEATURE LIFTS NORTHWARD TO OUR WEST
SAT NIGHT AND SUN, AND SHOULD ASSIST CONVECTION OVER OUR AREA AS IT
GOES.

SOME DRYING IS POSSIBLE OVER THE FAR WEST BEHIND THIS FEATURE SUN
AFTERNOON, BUT SWLY FLOW IS NOT STRONG ENOUGH OR LASTS LONG ENOUGH TO
CLEAR OUT MOISTURE...AND SCATTERED CONVECTION WILL RETURN TO JUST
ABOUT THE ENTIRE AREA BY MON AFTERNOON. CURRENT PATTERN WITH RIDGE
OVER THE ROCKIES AND GENERAL SOUTHERLY FLOW OVER OUR AREA REMAINS IN
PLACE WITH LITTLE CHANGE THROUGH THE WEEK SO HAVE KEPT A CHANCE
MENTION EACH DAY THRU THE EXTENDED.
