.SYNOPSIS...
HIGH PRESSURE WILL BRING DRY AND SUNNY CONDITIONS TO THE AREA
THROUGH THE HOLIDAY WEEKEND. A STORM SYSTEM WILL MOVE INTO THE WEST
COAST LATE THIS WEEKEND AND IMPACT OUR AREA NEXT WEEK.
&&

.SHORT TERM...THROUGH SATURDAY NIGHT...

A STRONG RIDGE REMAINS IN CONTROL ACROSS THE SOUTHWEST TODAY WITH
THE NEAREST SUBSTANCIAL CLOUD COVER ALL THE WAY UP IN NORTHWESTERN
NEVADA.  THE HIGH PRESSURE RIDGE WILL FLATTEN OUT A BIT TOMORROW
ALLOWING SOME PASSING HIGH CLOUDS TO ENTER OUR SKIES BUT OTHERWISE A
DRY AND MILD THANKSGIVING DAY IS IN STORE WITH TEMPERATURES 5 TO 10
DEGREES ABOVE NORMAL. WARM AND DRY CONDITIONS WILL CONTINUE FRIDAY
AND SATURDAY AS THE RIDGE SLOWLY BREAKS DOWN AND THE FLOW BECOMES
MORE ZONAL ACROSS THE COUNTRY.

.LONG TERM...SUNDAY THROUGH TUESDAY...

WHILE A SLOW COOLING TREND IS IN STORE FOR THE END OF THE HOLIDAY
WEEKEND AS HIGH PRESSURE WEAKENS ACROSS THE WESTERN
CONUS...TEMPERATURES WILL REMAIN ABOVE NORMAL THROUGH MONDAY. WINDS
WILL PICK UP ALONG THE SIERRA CREST SUNDAY AS THE PRESSURE GRADIENT
TIGHTENS IN RESPONSE TO AN APPROACHING PACIFIC STORM SYSTEM. MODELS
CONTINUE TO TREND SLOWER IN ITS TIMING. HAVE REDUCED CHANCES OF
PRECIPITATION EARLY IN THE EXTENDED PERIOD TO REFLECT THIS TREND.
WINDS WILL BECOME BREEZY AND SOUTHERLY ACROSS THE AREA AS THE STORM
SYSTEM GETS CLOSER.  AT THIS TIME IT LOOKS LIKE MOISTURE FROM THE
STORM WILL REACH THE SIERRA LATE MONDAY AND SPREAD ACROSS THE
FORECAST AREA ON TUESDAY. THERE IS SIGNIFICANT MODEL DISCREPANCY
REGARDING THE STRENGTH AND TIMING OF THIS SYSTEM. CONFIDENCE IS
MODERATE IN A MODERATE PRECIPITATION EVENT ACROSS THE AREA BUT
CONFIDENCE IS LOW IN ITS TIMING AND DURATION.
