GMZ300 Synopsis For High Island To The Matagorda Ship Channel Out 60 Nautical Miles Including Galveston And Matagorda Bays 928 Pm Cst Thu Feb 27 2020
Synopsis for high island to matagorda ship channel out 60 nm.. The continued presence of surface high pressure over southern texas will allow for light seas and north to northwest winds to continue through Friday. Winds may briefly approach caution thresholds on Friday afternoon but a widespread increase in winds is not anticipated until the redevelopment of onshore winds on Saturday as the surface high moves off to the southeast. By Saturday night caution flags or advisories will likely be needed across the nearshore and onshore waters with seas reaching 5 to 7 feet. We are continuing to Monitor the potential for possible sea fog development early next week but at this time wind speeds continue to be a limiting factor.

PREV DISCUSSION /Issued 544 PM CST Thu Feb 27 2020/.

SHORT TERM [Tonight through Friday]. The immediate forecast term will be characterized by calm and largely uneventful weather. Surface high pressure is expected to remain in place over Southern Texas heading into the weekend, which will allow for the lighter north to northwest winds and dry conditions to continue. Another cold night looks to be in store this evening with temperatures dipping into the 30s across most of the area, although a drop below freezing like we saw across the northern portion of the area last night is not expected. Friday is shaping up to be a gorgeous day with clear skies, temperatures around 70 degrees, and dew points in the mid 30s to low 40s. An onshore flow pattern will begin to redevelop overnight on Friday as high pressure slides eastward, which should pave the way for warm and moist conditions this weekend.

LONG TERM [Saturday Through Thursday]. Warm weather will be in full swing Saturday as southerly flow strengthens and upper ridging spreads across TX. Temperatures should climb into the mid 70s inland Saturday and Sunday with increasing dewpoints as WAA strengthens. Isolated showers possible Sunday mainly north of the I-10 corridor but again just isolated sprinkles beneath the strong subsidence inversion. Monday starts off very warm with lows in the lower to mid 60s and moderate to strong southerly winds. Fog threat looks low given the speed and trajectories. Rain chances gradually increasing to 30 percent across Walker/Polk counties northward for showers and climbing into the mid to upper 70s. Warmer still Monday night/Tuesday morning with abundant cloud cover as strong WAA prevails (overnight temperatures may be steady or even rising) and a vigorous upper level trough and s/w approaches the region. Tuesday expect showers and thunderstorms to develop along and ahead of a mild Pacific cold front sweeping quickly eastward through the state. Models of course differ on timing but in general late Tuesday afternoon-Wednesday 3 am looks to be the window for the greater impacts. Soundings support the potential for strong thunderstorms and SPC even has the area in a 15 percent Day 6 outlook. Wednesday should be much drier with wrap around cloud cover as low tracks off through LA and weak CAA takes place over SETX.

MARINE. Continued surface high pressure over Southern TX will provide light seas and offshore winds through Friday. Caution flags may briefly be required on Friday afternoon as winds look so strengthen to around 15 knots, but increases in winds should not become widespread until an onshore flow pattern redevelops on Saturday. Caution flags and/or advisories appear likely by Saturday night as departing surface high pressure will allow for the development of moderate southerly winds, with seas reaching around 5 to 7 feet. We are continuing to monitor the potential for possible sea fog development early next week, but at this time wind speeds continue to be a limiting factor.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
