DISCUSSION
A VERY WEAK COLD FRONT HAS DRIFTED INTO SOUTHERN UTAH
EARLY THIS MORNING. THE FRONT WILL DIMINISH TODAY. NET EFFECT OF
THE FRONT WILL BE A SHIFT IN THE TRANSPORT/FREE WINDS FROM THE SW
TO THE NW, WITH LITTLE CHANGE IN TEMPERATURE OR RH. FROM FRIDAY
INTO EARLY NEXT WEEK, A RIDGE OF HIGH PRESSURE WILL GRADUALLY
SETTLE INTO THE GREAT BASIN, FAVORING A WARMING TREND AND A
TENDENCY TOWARDS TERRAIN-DRIVEN WINDS. RIDGETOP WINDS WILL LARGELY
REMAIN WEST TO NORTHWEST UNTIL SUNDAY, WHEN THEY WILL BECOME
NORTHERLY. IT DOESN'T APPEAR THAT SOUTHERLY RIDGETOP WINDS WILL
MAKE A RETURN APPEARANCE FOR ABOUT A WEEK. ANOTHER CONSEQUENCE OF
THE BUILDING RIDGE WILL BE A TENDENCY TOWARDS POOR OVERNIGHT
RECOVERY, ESPECIALLY IN THE THERMAL BELT. A MODEST INCREASE IN
MOISTURE REMAINS POSSIBLE TOWARDS THE SECOND HALF OF NEXT WEEK,
ESPECIALLY BY THURSDAY AND BEYOND. HOWEVER, THERE REMAINS A
CONSIDERABLE AMOUNT OF UNCERTAINTY REGARDING NOT ONLY HOW MUCH
MOISTURE WE MIGHT GET, BUT ALSO TIMING AND LOCATION. AT THIS
POINT, THE MOST LIKELY SCENARIO POINTS TO A MODEST INCREASE IN
MOISTURE IN ABOUT A WEEK FROM NOW, MANIFEST BY ISOLATED SHOWERS
AND THUNDERSTORMS. WE'LL CONTINUE TO MONITOR THESE TRENDS.
