MOUNTAIN RANGE AND THE WESTERN CORDILLERA CENTRAL.

SCATTERED SHOWERS IS EXPECTED. FRIDAY AND SATURDAY MAY SEE SIMILAR
CONDITIONS AS TODAY...AS POCKETS OF MOISTURE FROM THE EAST COULD
MAKE THEIR WAY OVER THE ISLANDS. HOWEVER...AS THE MID-LEVEL HIGH
MOVES EASTWARD INTO THE CENTRAL ATLANTIC BY SATURDAY...THE
ASSOCIATED TRADE WIND CAP WILL INTERVENE AND LIMIT DEEP CONVECTION
FROM FORMING. BY SUNDAY AND INTO MONDAY...THE MID-LEVEL RIDGE
MOVES FURTHER EAST AND THE TRADE WIND INVERSION CAP MAY BEGIN TO
SHOW SINGS OF BREAKING. CONDITIONS ARE EXPECTED TO REMAIN FAIR AND
NO SIGNIFICANT AMOUNT OF PRECIPITATION IS FORECAST. PRECIPITATION
TOTALS OVER PUERTO RICO ARE EXPECTED TO STAY BELOW 0.2 INCHES FOR
THE NEXT FIVE DAYS.
