SUMMARY OF FWF DISCUSSIONS

Discussion from LAXFWFSGX


PERIODS OF GUSTY NORTHEAST WINDS WILL CONTINUE ALONG THE COASTAL
SLOPES OF THE MOUNTAINS AND ADJACENT FOOTHILLS AREAS THROUGH
SATURDAY MORNING. WEAKER WINDS WITH CONTINUE BELOW AVERAGE
TEMPERATURES FOR SUNDAY AND MONDAY. FOR TUESDAY THROUGH THURSDAY OF
NEXT WEEK...A COLD LOW PRESSURE SYSTEM FROM THE NORTH COULD BRING
PERIODS OF PRECIPITATION AND GUSTY WINDS WITH WELL BELOW AVERAGE
TEMPERATURES.


Discussion from LAXFWFLOX


A STRONG...BUT RATHER DRY...COLD FRONT WILL SWEEP ACROSS THE AREA
TONIGHT AND CHRISTMAS MORNING. AT THIS TIME...THE ONLY SHOWERS
EXPECTED WITH THIS FRONT WILL OCCUR ON THE NORTH-FACING SLOPES
TONIGHT AND CHRISTMAS MORNING...WITH SNOW SHOWERS POSSIBLY IMPACTING
THE I-5 THROUGH THE GRAPEVINE. THE BIGGER IMPACT FROM THIS FRONTAL
PASSAGE WILL BE STRONG NORTHWEST TO NORTH WINDS TONIGHT AND CHRISTMAS
DAY. POTENTIALLY DAMAGING GUSTS TO AROUND 65 MPH ARE LIKELY IN THE
LOCAL MOUNTAINS...WITH GUSTS OF 30 TO 50 MPH LIKELY ACROSS MANY VALLEY
AND COASTAL LOCATIONS. THE NORTHERLY WINDS WILL USHER IN A VERY COLD
AIR MASS...AND HIGHS ON CHRISTMAS DAY WILL BE SEVERAL DEGREES BELOW
SEASONAL NORMALS.

FOR THURSDAY NIGHT THROUGH SATURDAY...THE FLOW WILL TURN TO THE
NORTHEAST...AND MODERATE NORTHEAST WINDS ARE EXPECTED ACROSS THE
AREA. THE COMBINATION OF A COLD AND DRY AIR MASS...ALONG WITH THE
DRYING EFFECTS OF THE OFFSHORE WINDS...WILL RESULT IN LOW RELATIVE
HUMIDITY THROUGH THE PERIOD WITH ONLY POOR TO MODERATE OVERNIGHT
RECOVERIES.

ON SUNDAY...THERE WILL BE A BIT OF A LULL WITH RESPECT TO OFFSHORE
WINDS. HOWEVER BY LATE SUNDAY NIGHT AND MONDAY...ANOTHER ROUND OF
MODERATE NORTH TO NORTHEAST WINDS IS POSSIBLE.


Discussion from SFOFWFHNX

A RIDGE OF HIGH PRESSURE WILL BUILD IN FROM THE
PACIFIC THROUGH SATURDAY PROVIDING DRY CONDITIONS. A TROUGH OF
LOW PRESSURE IS EXPECTED TO MOVE IN FROM THE NORTH EARLY NEXT
WEEK AND BRING INCREASED WINDS AND A CHANCE OF PRECIPITATION.


Discussion from RNOFWFVEF

A COLD NORTHERLY FLOW WILL REMAIN OVER THE REGION
RESULTING IN NORTH WINDS CONTINUING THROUGH SATURDAY MORNING. THIS
COLDER AIR MASS WILL REMAIN IN PLACE THROUGH THE WEEKEND AND
ANOTHER...POTENTIALLY COLDER SYSTEM WILL APPROACH THE AREA BY EARLY
NEXT WEEK BRINGING ADDITIONAL COLD AIR ALONG WITH A SLIGHT CHANCE OF
LOW ELEVATION SNOW.


Discussion from PHXFWFPSR


A COLD...BUT DRY LOW PRESSURE SYSTEM WILL LINGER OVER THE REGION
TODAY. EXPECT LOCALLY GUSTY NORTH TO NORTHWEST WINDS AT TIMES ALONG
THE LOWER COLORADO RIVER VALLEY...WITH GENERALLY LIGHT SURFACE WINDS
ACROSS THE REMAINING DISTRICTS. THE DRIER AIR WILL YIELD MOSTLY SUNNY
SKIES...AND IT WILL GRADUALLY TREND DOWN DAYTIME HUMIDITY LEVELS OVER
THE NEXT COUPLE OF DAYS.

NOTE...ADDITIONAL FIRE WEATHER FORECAST INFORMATION CAN BE FOUND
IN THE AREA FORECAST DISCUSSION. SEE PRODUCT PHXAFDPSR.
