AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
941 PM AST SAT OCT 27 2012

.UPDATE...VERY QUIET EVENING TODAY COMPARED WITH YESTERDAY EVENING. THE
DOPPLER WEATHER RADAR DETECTED ONLY ISOLATED SHOWERS ACROSS SOUTHERN
SECTIONS OF PUERTO RICO AS WELL AS ACROSS THE SURROUNDING COASTAL
WATERS LATE THIS EVENING. NO SIGNIFICANT PRECIPITATION WAS OBSERVED
ELSEWHERE ACROSS THE LOCAL ISLANDS. A SOUTHERN OR SOUTHWESTERLY LOW
LEVEL WIND FLOW IS EXPECTED TO CONTINUE ACROSS THE REGION FOR THE
NEXT SEVERAL DAYS. THIS FLOW PATTERN WILL INDUCE THE DEVELOPMENT OF
ISOLATED TO SCATTERED SHOWERS ACROSS SOUTHERN SECTIONS OF PUERTO
RICO DURING THE NIGHTS AND EARLY IN THE MORNING AND SCATTERED
SHOWERS WITH ISOLATED THUNDERSTORMS ACROSS NORTHERN SECTIONS OF
PUERTO RICO EACH AFTERNOON. A RETURN TO THE NORMAL TRADE WIND FLOW
PATTERN IS EXPECTED BY MID WEEK.

&&

.AVIATION...EXPECT PREVAILING VFR CONDITIONS ACROSS THE LOCAL
ISLANDS AND AT ALL TAF SITES DURING THE NEXT 24 HOURS. HOWEVER...
BRIEF MVFR CONDITIONS AND LOCAL MOUNTAIN OBSCURATIONS ARE POSSIBLE
OVERNIGHT IN ISOLATED TO LOCALLY SCATTERED SHOWERS.

&&

.PREV DISCUSSION... /ISSUED 307 PM AST SAT OCT 27 2012/

SYNOPSIS...UPPER LEVEL RIDGE WILL REMAIN THE DOMINANT WX FEATURE
INTO MON THEN BREAK DOWN TEMPORARILY ON TUE AS POLAR TROUGH
AMPLIFIES ACROSS ERN NOAM. RIDGE WILL BUILD AGAIN LATE NEXT WEEK.

DISCUSSION...CONVECTION HAS BEEN VERY MINIMAL TODAY DUE TO STRONG
SRLY DOWNSLOPE FLOW AND LACK OF SFC CONVERGENCE. HOTTER TOMORROW
WITH WARMER 1000-850 MB THICKENESSES AND STRONGER CAP. ON
MON...THICKNESSES DROP AS A RIDGE START TO BREAK DOWN IN RESPONSE
TO DIGGING TROF ACROSS ERN US. A SHORTWAVE-TROUGH EMBEDDED IN
SWRLY FLOW WILL MOVE ACROSS THE AREA MON AND LIKELY RESULT IN A
MORE ACTIVE DAY. DRIER AIR WILL START WORKING INTO THE AREA TUE
WITH LESS CVRG. MUCH DRIER AND STABLE FOR MID WEEK AS ERN US TROF
DEAMPLIFIES AND UPPER LEVEL RIDGE STARTS BUILDING IN AGAIN.
WEATHER MID TO LATE NEXT WEEK WILL BE MORE REMINISCENT OF MID TO
LATE NOVEMBER.

AVIATION...VFR CONDS WILL PREVAIL ACROSS MOST OF THE TAF SITES
THROUGH THE FORECAST PERIOD...EXCEPT IN TJSJ WHERE MVFR CONDS ARE
POSSIBLE IN PASSING SHRA/TSRA THROUGH 27/21Z.

MARINE...SEAS ARE CURRENTLY 3 TO 6 FEET BUT EXPECTED TO BUILD
RAPIDLY LATE SUN NIGHT IN NORTHWEST SWELLS. SCA AND HIGH SURF
ADVISORIES WILL BE REQUIRED FOR MUCH ON NEXT WEEK.
