SOUTHEAST UTAH THIS EVENING. COMBINED WITH THE CONTINUED MOIST

SATURDAY...ALLOWING FOR A BRIEF DRYING TREND. MODELS INDICATE PWS
DROPPING IN THE 0.5 TO 0.75 RANGE BY SATURDAY AFTERNOON ACROSS THE

WARMING TREND...ALLOWING TEMPERATURES TO RISE TO NEAR CLIMO OVER
NORTHERN AND CENTRAL UTAH BUT STILL A BIT BELOW THOSE VALUES OVER
SOUTHERN UTAH.

GFS/EC STILL SHOWING THE RIDGE SHIFTING JUST EAST OF THE AREA
SUNDAY AS A WAVE MOVES UP INTO THE STATE SUNDAY/MONDAY...ALLOWING
MONSOONAL MOISTURE TO MOVE BACK NORTHWARD FOR EARLY NEXT WEEK.

TRENDS. NO OTHER UPDATES ANTICIPATED THIS EVENING.
