Forecast Discussions mentioning "ACARS", "MDCRS", or "AIRCRAFT" received at FSL on 02/06/02

ONLY THING TO WORRY ABOUT OVERNIGHT IS THE FORMATION OF FOG WHICH MAY BE LOCALLY DENSE. KVBG SOUNDING SHOWED A 500 FOOT DEEP MARINE LAYER AND EVENING ACARS DATA AROUND THE LA BASIN REALLY DID NOT SHOW MUCH OF A MARINE LAYER AT ALL. SAT PIX SHOWING LOW CLOUDS POOFING AROUND PT CONCEPTION AND LPC. ALSO NOTED THAT LOCATIONS ALONG ALL OF THE IMMEDIATE COAST ARE NEARLY SATURATED. IN FACT KSMO IS SATURATED IN THE LOWER 50S WITH LIGHT FOG ALREADY REPORTED. SINCE THE MARINE LAYER IS SO SHALLOW...ANY FOG THAT DOES FORM WILL LIKELY BECOME DENSE. AS YOU MOVE INLAND DEWPOINTS DROP CONSIDERABLY...SO STILL EXPECT TO SEE A CHILLY NIGHT AWAY FROM THE COAST. WILL UPDATE ZONES THIS EVENING TO ADJUST MINS ALONG THE COAST UP A LITTLE...AND TO OPEN UP A LARGER SPREAD IN THE MTNS. MANY LOCATIONS IN THE MTNS WILL ONLY GET DOWN INTO THE 40S...WHILE THE HIGHER VALLEYS WILL STILL SEE SOME TEENS.

OVERALL...THE NEXT WEEK LOOKS BENIGN. THE UPR RIDGE FLATTENS WED AND THURS AS ENERGY AND MOISTURE STREAMS INTO THE PAC NW. GRADS WILL TREND ONSHORE THE NEXT TWO DAYS...YIELDING A STRONGER SEA BREEZE INFLUENCE...AND COOLER TEMPS COASTSIDE. LOW CLOUDS AND FOG WILL PROBABLY BE MORE PREVALENT WED NIGHT AS SOME WEAK SHORTWAVE ENERGY PASSES BY. THEN UPR RIDGE BUILDS BACK OVER THE AREA FOR THE WEEKEND...WARMING THINGS BACK UP A LITTLE.

.SYNOPSIS...SLOW DAYTIME COOLING WILL DEVELOP INLAND FROM THE COAST THROUGH FRIDAY WITH NIGHT AND MORNING COASTAL LOW CLOUDS SLOWLY RETURNING. BUILDING HIGH PRESSURE ALOFT AND WEAK OFFSHORE FLOW WILL BRING MOSTLY CLEAR SKIES AND WARMER TEMPERATURES FOR THE WEEKEND. LOCALLY BREEZY AND A LITTLE COOLER FOR EARLY NEXT WEEK AS A WEAK TROUGH OF LOW PRESSURE MOVES INLAND ACROSS SOUTHERN CALIFORNIA.

.DISCUSSION...AVN IS NOW IN GOOD AGREEMENT WITH THE ECMWF THRU THE WEEKEND. PREFER THE WKR ECMWF SOLUTION FOR MON/TUE IN MOVG A WKR UPR TROUGH INLAND ACROSS SRN CA. PATCHY STRATUS HAS RETURNED OVR THE CSTL WTRS EXTENDING LCLLY INLAND. WITH ACARS SOUNDINGS SHOWING A NR SURFACE BASED INVERSION...STRATUS SHOULD BE CONFINED CLOSE TO THE CST THIS MORNING...MOSTLY IN THE FORM OF DENSE FOG. HEIGHTS ALF LWR A LTL DURG THE NEXT 24 HOURS ALLOWING THE MARINE LYR TO DEEPEN A LTL TONIGHT AND THU WITH STRATUS EXTENDING A LTL FARTHER INLAND. GREATEST STRATUS COVERAGE THE NEXT FEW NIGHTS SHOULD BE THU NIGHT INTO FRI MORNING WITH LOW CLOUDS EXTENDING LCLLY INTO THE LWR CSTL VLYS. OFFSHORE FLOW FOR SAT/SUN MORNINGS SHOULD BE MOSTLY SURFACE GRADIENT DRIVEN WITH SURFACE HIGH PRESSURE ONCE AGAIN CNTRD TOO FAR E...UT AND WRN CO...TO PUSH WINDS TO ADV LEVELS. WITH A LTL STRONGER RDG ALF AND WK OFFSHORE FLOW...WEEKEND TEMPERATURES SHOULD BE A LTL WARMER THAN THOSE OF THE PAST TWO DAYS. A LTL COOLER FOR MON AND TUE AS THE WK UPR TROUGH MOVES INLAND ACROSS SRN CA.

CSTL WTRS...NW SWELL GENERATED BY THE STORM IN THE GULF OF AK AND NORTHEAST PAC WL BRING AN INCR IN SURF TO SW CA BEACHES THU... SUBSIDING FRI. SURF SHOULD REMAIN JUST BLO HVY SURF LVLS DURG THE PK OF THE EVENT.

.SAN...NONE.
