GMZ300 Synopsis For High Island To The Matagorda Ship Channel Out 60 Nautical Miles Including Galveston And Matagorda Bays 928 Am Cst Fri Dec 6 2019
Synopsis for high island to matagorda ship channel out 60 nm.. A cold front will be passing through the gulf water through the early afternoon. Drier air behind the front will help dissipate the fog that developed this morning. Isolated showers could form along this boundary as it moves through the gulf. Winds will also pick up behind the front, and are expected to be strong enough to prompt caution flags for this afternoon and into the night. Onshore winds are set to return Sunday. Another front may pass through the region Monday night with a better chance of showers with it and a moderate to strong offshore flow developing in its wake.

AVIATION [18Z TAF Issuance].

The front has pushed through the region leaving mostly sunny skies and breezy northerly flow behind it. Gusts up to 20 mph are possible through this evening. Some mid level clouds return towards sunrise tomorrow, but otherwise expect VFR conditions trough the period.

PREV DISCUSSION /Issued 942 AM CST Fri Dec 6 2019/.

UPDATE.

Cold front is just about to exit off the coast bringing an end to most of the foggy conditions. There is still some lingering fog down near Galveston, Angleton, and Bay City, but this should be dissipating within the next hour. Thus, going to let the marine dense fog advisory in Matagorda Bay to expire at 10 AM as planned. The rest of the day will be relatively quiet with partly cloudy skies with a breezy northerly wind that will continue through the evening. Temperatures behind the front are actually not that much colder, but the air is much drier. This combined with the breeze today will make today feel quite a bit cooler than yesterday.

Fowler

SHORT TERM [Through Saturday].

Surface obs show that the approaching weak cold front is still to the northwest of our area, and expectations are that it will reach College Station around or just before dawn, the Houston metro by mid-morning, and push offshore and across the Gulf mid-day into the afternoon. Until then, look for fog to develop ahead of the front, particularly near the coast, and some more dense fog is already beginning to crop up around and a little northeast of Matagorda Bay. Shouldn't be widespread enough to need a dense fog advisory, buuuuttttt . I'm not sure I'd rule it out yet either.

Taking a glance at the radar up north around the front, it is pretty sparse except around Texarkana where there are some showers. Did go with an oh, so slight chance of showers near the coast . perhaps we'll gin up enough moisture and isentropic lift closer to the Gulf to manage a couple brief showers. It'd be a surprise to get anything more than an isolated shower or two, though.

Beyond that, look for breezier northwest winds with gusts of 15-25 mph (highest in the northwest) to usher in some drier and cooler air for Saturday, which will be mostly clear and have diminishing winds.

Luchs

LONG TERM [Saturday Night Through Friday].

A return of onshore winds will begin tomorrow night (Saturday night) as high pressure starts moving off to the east. After a cool morning on Sunday (lows ranging from the mid to upper 40s inland to the mid to upper 50s at the coast), strengthening south winds will result in afternoon highs warming into the 70s across the area. This onshore flow and associated early December warming trend will continue on into Sunday night (lows in the 50s/60s) and Monday (highs in the 70s/80s that might get within a couple degrees of the records for the 9th as winds become a little more southwesterly). This short warming trend comes to an end Monday night through Tuesday morning with the passage of the area's next cold front. Right now, it looks like temperatures will fall back into the 40s/50s behind the front on Tuesday morning, and the area will only warm up into the 50s/60s during the day as high pressure begins to build in from the north. Temperatures will be staying on the cool side (below normal) for the remainder of the week. Best rain chances for the week look to come in the Monday night-Tuesday time period in association with the frontal passage, but we will continue to keep some rain in the forecast for much of the remainder of the week until models come into better agreement on the development/strength/timing of the next trof and associated shortwaves. 42

MARINE.

Visibility has dropped significantly on Matagorda Bay, and a dense fog advisory has been issued for the area until 10 am - roughly when a cold front will pass through the area and put an end to the fog threat.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
