Synopsis for the middle texas coastal waters.. Weak to moderate onshore flow is expected to continue today with showers and the possibility of Thunderstorms across the bays and open waters until this afternoon. Beginning tonight after the passage of the front, the winds are expected to pick up to about 20 to 25 knots out of the north-northwest. Therefore, a small craft advisory might be needed for the local waters during that period. High pressure will build into the area on Wednesday resulting in a weak to moderate offshore flow with waves up to 6 feet.moderate onshore winds develop Wednesday night ahead of the next upper disturbance. This system will bring scattered to numerous showers Thursday into early Friday, before moderate to strong offshore winds with a cold front bring drier conditions throughout Friday afternoon. Weak to moderate offshore winds on Saturday become onshore by Sunday, then increase to moderate to strong on Monday afternoon with some showers at times ahead of another upper disturbance.

SHORT TERM (Today through Wednesday).

Rain showers are expected across the area today with the possibility of thunderstorms. Several models such as the GFS and RAP are showing decent amounts of CAPE across the area today which may lead to some thunderstorms associated with the passage of the cold front. Therefore, a chance of thunder was included in the forecast over the majority of the CWA. After the passage of the cold front late this morning/early this afternoon the weather is expected to improve rapidly and remain pleasant as high pressure builds in behind into the area. Southerly winds this morning will advect some warm air that will allow the high temperatures to range between the mid 70's to the lower 80's. Minimum temperatures tonight are expected to be in the 40s across the entire CWA with the colder temperatures being inland. Tomorrow we can expect sunny skies with high temperatures in the mid to upper 60's.

LONG TERM (Wednesday Night through Tuesday).

Models are converging nicely with the next upper trough diving through the Desert Southwest Wed night before passing over South TX Thu night. Although the finer mesoscale details and QPF output vary considerably between models, the overall pattern remains favorable for potentially two rounds of showers - the first beginning Thu afternoon with the onset of isentropic lift, and the second and much more deeply forced round expected Thu night with the arrival of the upper trough,140+ knot jet around 200 mb, and richest PWATs just over 1 inch. By 12Z Fri, a cold front will be sweeping offshore ahead of breezy north winds and much drier air. PoP grids on Fri were split in half to better capture this drying theme. In the wake of Thu night's trough, a trailing impulse is progged to dive into northern Mexico Fri night while retrograding over Baja CA and closing off into a weak low. The remnants of this low should phase with a northern stream trough late in the weekend before lifting over S TX on Mon. Moisture recovery ahead of this wave is looking meager at the moment, but just enough to keep some shower chances on Mon across the eastern third of our domain.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
