DISCUSSION
HIGH PRESSURE WILL DOMINATE THE REGION THROUGH THE FORECAST AND
WILL KEEP THE AREA DRY WELL INTO NEXT WEEK. THIS WILL ALSO KEEP
WINDS ON THE LIGHT SIDE THROUGH THE FORECAST AS WELL. MIN RH
VALUES FROM DRY AIRMASS WILL BE 40-50% FOR THE AREA FOR THE
FORECAST PERIOD. MOISTURE DOES START TO SLOWLY RECOVER ABOVE THAT
FOR THE FORESEEABLE FUTURE. NO RAIN IN THE FORECAST AT THIS TIME
EITHER.
HIGH PRESSURE BRINGS GENERALLY LIGHT AND VARIABLE WINDS ESPECIALLY
NEAR SHORE WITH LIGHT EASTERLY WINDS OVER THE OUTER WATER
WEDNESDAY NIGHT. THURSDAY WE WILL SEE HIGH PRESSURE START TO SETTLE
BACK DOWN INTO THE NORTH-CENTRAL AND NORTHEASTERN GULF BEFORE IT
FINALLY BECOMES SITUATED OVER THE EASTERN GULF THIS WEEKEND. THIS
WILL CONTINUE TO LEAD TO LIGHT AND VARIABLE WINDS THURSDAY AND THEN
A SLOW BUT STEADY TURN TO SOUTHERLY AND SOUTHWESTERLY WINDS (ONSHORE
FLOW) THIS WEEKEND. THE LIGHT WINDS WILL LEAD TO LOW WAVES/SEAS
2-3 FT OR LESS THROUGH THE FORECAST.
