Forecast as of 12:31 PM CST on November 21, 2009
Synopsis For The Middle Texas Coastal Waters
A surface low pressure system will move from the northwest Gulf into the northern Gulf today and tonight. This will result in a gradual decrease in the offshore flow and seas through tonight. Weak high pressure located over the waters on Sunday morning will move east by the afternoon. This will allow a weak onshore flow to develop by Sunday afternoon. A weak to moderate onshore flow will persist on Monday. A cold front is expected to move across the coastal waters by Tuesday afternoon with a strong offshore flow developing in its wake. An upper level disturbance will bring a chance of showers and thunderstorms on Monday with a chance continuing on Tuesday along the cold front.
