400 PM PDT TUE APR 10 2007

UPDATED AVIATION DISCUSSION

.SHORT TERM (TONIGHT-FRIDAY)...WILL ISSUE A HIGH WIND WATCH THIS
AFTERNOON FOR THE MOUNTAINS THIS AFTERNOON WITH THE PERIOD OF
CONCERN LATE WEDNESDAY NIGHT AND THURSDAY WHEN THE NAM12 MODEL SHOWS
45 TO 50 KT OF WIND AT 850 MB AND A NORTH JET OF 120 KT AT 250 MB.

BOTH THE NAM12 AND THE GFS HAVE COME TO A BETTER CONSENSUS REGARDING
THE EVOLUTION OF THE SYNOPTIC PATTERN LATER THIS WEEK. BOTH MODELS
SHOW AN EVOLVING TROUGH FOLLOWING THE TRAJECTORY OFTEN REFERRED TO
AS AN INSIDE SLIDER...WHICH WOULD TAKE MOST OF THE SYNOPTIC LIFT AND
PRECIPITATION POTENTIAL EAST OF THIS DISTRICT. ACTUALLY THE LATEST
RUNS OF THE MODEL ARE TAKING THE TROUGH A LITTLE FURTHER EAST THAN
PREVIOUS RUNS...WHICH WOULD PLACE CURRENT POPS FOR WEDNESDAY NIGHT
IN JEOPARDY. WILL ADJUST THE POPS DOWNWARD IN THE NORTHERN ZONES. IT
STILL APPEARS THAT THE NORTHERN SLOPES OF THE MOUNTAINS STILL HAVE
GOOD POTENTIAL FOR SOME LIGHT SNOW SHOWERS WEDNESDAY NIGHT AND
THURSDAY WITH THE SNOW LEVEL DROPPING TO ABOUT 5000 FEET LATE
WEDNESDAY NIGHT OR THURSDAY WITH THE ARRIVAL OF COLD AIR.

THE POTENTIAL FOR WIND REMAINS UNCHANGED HOWEVER...AS A STRONG NORTH
JET RESPONSIBLE FOR DRIVING THE TROUGH SOUTHEAST INTO THE GREAT
BASIN LINES UP OVER OUR DISTRICT WEDNESDAY NIGHT AND THURSDAY.
STRONG WINDS ARE FORECAST ALL THE WAY DOWN TO 850 MB LATE WEDNESDAY
NIGHT AND THURSDAY. IF STRONG GUSTY WINDS COMBINE WITH SNOW
SHOWERS...TRAVEL COULD BE FAIRLY TREACHEROUS IN PORTIONS OF THE
MOUNTAINS DURING THIS PERIOD.

.LONG TERM (SATURDAY-TUESDAY)...ANOTHER TROUGH CIRCUMNAVIGATES THE
FORECAST AREA OVER THE WEEKEND WITH ALL OF THE ENERGY STAYING TO THE
NORTH AND EAST OF THE FORECAST AREA. BASICALLY...THIS SYSTEM WILL BE
ANOTHER INSIDE SLIDER. PARTLY CLOUDY SKIES AND BREEZY CONDITIONS
SHOULD BE THE EXTENT OF THE EFFECTS. BY EARLY NEXT WEEK...A RIDGE
BUILDS IN OVER SOUTHWEST CALIFORNIA FOR DRY AND WARMER CONDITIONS.

&&

.AVIATION...10/2300Z...
VFR CONDITIONS WILL PREVAIL AT ALL AIRFIELDS THROUGH MOST OF
TONIGHT. MAIN CONCERN WILL CONTINUE TO BE THE WINDS. GUSTY NW WINDS
WILL CONTINUE AT KSBP KSMX KPMD AND KWJF THROUGH ABOUT 03Z. LLWS MAY
BE A CONCERN AS WELL...ESPECIALLY AT KSBA AND KVNY...BUT NOT
CONFIDENT THAT IT WILL REACH +/- 20KT BELOW 020. WINDY DAY ON TAP ON
WED AND THU. STRATUS SHOULD ONLY IMPACT KLAX AND KLGB OVERNIGHT.

KLAX WILL BE VFR THROUGH MOST OF TONIGHT...WITH A CHANCE OF BKN018
CIGS FORM NEAR THE AIRPORT AFTER 10Z...BUT WILL BE PATCHY IN NATURE.
 WESTERLY SEABREEZE CONTINUE AROUND 12 KT THROUGH ABOUT 04Z...THEN
GO LIGHT. GUSTY W TO NW WINDS EXPECTED WED AFTERNOON.

KBUR WILL BE VFR THROUGH TONIGHT. SOUTHERLY SEABREEZE NEAR 10 KT
SHOULD CONTINUE THROUGH 03Z...THEN GO LIGHT. NO STRATUS EXPECTED.
STRONGER THAN NORMAL SEABREEZE EXPECTED WED.

&&

MARINE...10/2300Z...
STRONG NW FLOW WILL CONTINUE THROUGH LATE THURSDAY NIGHT...PEAKING
THURSDAY AFTERNOON AND EVENING...WITH WIDESPREAD GALE CONDITIONS
OVER THE OUTER WATERS. THE INNER WATERS SHOULD SEE SMALL CRAFT
CONDITIONS BY WED NIGHT...WITH A CHANCE OF GALE CONDITIONS OVER THE
SANTA BARBARA CHANNEL WEDNESDAY AND THURSDAY EVENINGS. IN
ADDITION...A LARGE NW SWELL AND A MODERATE SOUTHERLY SWELL WILL
BUILD THROUGH THE WEEK...WITH WIDESPREAD SEAS WELL ABOVE 10 FT OVER
THE OUTER WATERS THROUGH FRIDAY...AND POSSIBLY TOUCHING 10 FT OVER
INNER WATERS LATE WEDNESDAY. THIS COMPLEX SWELL WILL CREATE HIGH
SURF OVER THE FOUR COUNTY AREA...AND HIGH SURF ADVISORIES WILL
LIKELY BE NEEDED...ESPECIALLY WEDNESDAY AND THURSDAY.
