TH

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE EUREKA CA
906 AM PST SAT JAN 13 2007

.SYNOPSIS...COLD AND DRY CONDITIONS ARE EXPECTED TO CONTINUE OVER
NORTHWEST CALIFORNIA THROUGH THE WEEKEND. A WEAK LOW PRESSURE
SYSTEM WILL MOVE OVER THE COAST ON TUESDAY.

&&

.UPDATE...
REMOVED FREEZE WARNING HEADLINES FOR THE REDWOOD AND MENDOCINO
COASTS. CURRENT COASTAL TEMPERATURES ARE GREATER THAN 29 DEGREES AND
NO LONGER SUPPORT HARD FREEZE CONDITIONS. SOME INLAND COASTAL SITES
STILL HAVE TEMPERATURES BELOW 29 AND EXPECT PATCHY FOG TO CONTINUE
THROUGH THE MORNING.

&&

.DISCUSSION...LITTLE CHANGE EXPECTED THROUGH SUNDAY AS A COLD AND
DRY AIRMASS HAS SETTLED OVER THE FORECAST AREA. THE DEWPOINTS WILL
REMAIN IN THE LOWER TEENS TO MID 20S ACROSS THE CWA. THE
TEMPERATURES RANGE FROM THE LOWER TO UPPER 20S IN THE COASTAL
REGION. SO HAVE CONTINUED THE FREEZE WARNING UNTIL 900 AM THIS
MORNING. THE SKIES WILL REMAIN CLEAR TO MOSTLY CLEAR TODAY THROUGH
SUNDAY. STRONG RADIATIVE COOLING TONIGHT WILL MEAN ANOTHER NIGHT OF
VERY COLD TEMPERATURES. THE 1000 TO 500 MB THICKNESS VALUES BETWEEN
THIS MORNING AND SUNDAY MORNING ARE VERY SIMILAR. WITH NO COLD
ADVECTION AND SOME MODIFICATION TO THE AIR MASS BY DIURNAL
HEATING...THE LOW TEMPERATURES FOR SUNDAY MORNING MAY NOT BE AS LOW
AS THIS MORNING.  HOWEVER...MANY LOCATIONS ALONG THE COAST WILL
STILL SEE LOWS IN THE 20S...SO HAVE CONTINUED THE FREEZE WATCH FOR
TONIGHT INTO SUNDAY MORNING. THE MODELS INDICATE A MORE SIGNIFICANT
WARMING AT H85 TO BEGIN SUNDAY AFTERNOON. SO THE COASTAL REGION
SHOULD SEE A MODERATION IN THE OVERNIGHT LOWS FOR SUNDAY NIGHT AND
MONDAY MORNING.

A STRONG UPPER LEVEL RIDGE WILL BUILD OVER THE EASTERN PACIFIC
TODAY. THIS WILL KEEP US IN A DRY PATTERN AND A GRADUAL WARMING
TREND THROUGH MONDAY. THE RIDGE WEAKENS AND MOVES INLAND MONDAY
NIGHT AS AN UPPER LEVEL TROUGH APPROACHES THE PACIFIC NORTHWEST. THE
MODELS TEND TO AGREE THAT A CUT-OFF LOW WILL DEVELOP IN THE BASE OF
THE TROUGH...WITH THE NORTHERN PORTION OF THE TROUGH MOVING INTO
WASHINGTON STATE. THE MODELS ARE STILL NOT IN GOOD AGREEMENT WITH
THE MOVEMENT OF THE CUT-OFF LOW. THE GFS REMAINS CONSISTENT IN
DROPPING THE LOW SOUTHWARD ALONG THE WEST COAST...WHILE THE ECMWF
BRINGS THE LOW INLAND ACROSS NORTHERN CALIFORNIA AND SOUTHERN
OREGON...THEN MOVES IT SOUTHEASTWARD TOWARD LAS VEGAS NEVADA. I
GENERALLY FOLLOWED THE ECMWF SOLUTION...AND HAVE CONTINUED THE
SLIGHT CHANCE OF SHOWERS OVER THE COASTAL WATERS AND THE REDWOOD
COAST FOR TUESDAY AND TUESDAY EVENING. THE SYSTEM IS EXPECTED TO BE
WEAK AND MOVE THROUGH THE AREA FAIRLY QUICKLY...ANY PRECIPITATION
WILL BE LIGHT. HOWEVER...DEPENDING ON THE MOVEMENT OF THE CUT-OFF
LOW THE NORTHERN PART THE NORTH COAST INTERIOR COULD POTENTIALLY
HAVE SCATTERED SHOWERS AND MAY NEED TO BE INCLUDED IN THE AREA OF
SHOWERS.

BY WEDNESDAY...THE  RIDGE REBUILDS OVER NORTHERN CALIFORNIA SO THE
REST OF THE FORECAST PERIOD REMAINS DRY.

.AVIATION....COLD HIGH PRESSURE AND LIGHT OFFSHORE FLOW TO PRODUCE
VFR CONDITIONS. FEW CUMULUS ALONG HIGHER TERRAIN OF TWEB ROUTES
POSSIBLE AFTER 20Z. NO IMPACTS EXPECTED.
