A LOW IS PROGGED TO TRACK ALONG THE CALIFORNIA COAST THROUGH
TOMORROW BEFORE QUICKLY MOVING EASTWARD BEGINNING
THURSDAY...MAKING ITS WAY ACROSS SOUTHERN UTAH ON FRIDAY. MOISTURE
WILL BE ON THE INCREASE OVER SOUTHWEST UTAH TOMORROW...ALLOWING
FOR A FEW SHOWERS OVER THE TERRAIN. INCREASED MOISTURE ALONG WITH
INCREASED INSTABILITY AHEAD OF THE LOW WILL ALLOW FOR BETTER
COVERAGE OF CONVECTION OVER SOUTHERN UTAH ON THURSDAY. INCREASED
CLOUDS WILL ALSO RESULT IN A DECREASING TEMPERATURE TREND FOR THE
SOUTH BY THURSDAY. MEANWHILE...MAXES IN THE NORTH WILL BE AS HIGH
AS 10F ABOVE CLIMO AWAY FROM THE CLOUDS AND CONVECTION.
THE SYSTEM IS EXPECTED TO PUSH ACROSS SOUTHERN UTAH
FRIDAY...ALLOWING PRECIPITATION TO BECOME MORE WIDESPREAD AND
SPREAD INTO NORTHERN UTAH BY FRIDAY AFTERNOON. ABUNDANT CLOUD
COVER AND COOLER 700 MB TEMPS SHOULD BRING TEMPS BACK AROUND CLIMO
OVER THE NORTH...AND UP TO 10F BELOW THOSE VALUES OVER SOUTHERN
UTAH. PRECIPITATION WILL MOSTLY FALL AS RAIN...WITH SNOW POSSIBLE
AT HIGH PEAKS ABOVE ABOUT 9000 FEET. THE LAST FEW MODEL RUNS HAVE
SHOWN VERY GOOD RUN-TO-RUN CONSISTENCY...AND GLOBAL MODELS ARE
SHOWING BETTER THAN USUAL AGREEMENT...SO FORECASTER CONFIDENCE IS
HIGHER THAN USUAL.
MODELS INDICATE THE STORM SYSTEM WILL QUICKLY EXIT THE AREA ON
SATURDAY...ALLOWING FOR A DRIER NORTHWESTERLY FLOW TO DEVELOP.
COMPUTER MODELS INDICATE A RIDGE WILL GENERALLY DOMINATE THE WEATHER
PATTERN THROUGH EARLY NEXT WEEK...THOUGH A TROUGH MOVING OVER THE
RIDGE WILL WEAKEN IT AND GRAZE NORTHERN UTAH DURING THE DAY MONDAY
BEFORE HIGH PRESSURE BUILDS BACK BEGINNING AT DAY 7.
