Marine Weather and Tides
Version 3.4 |
8/26/2020 The 7 day forecast is taking about 5 seconds to load but it will eventually load. NOAA is still working on it. 8/18/2020 NOAA continues to have trouble. Wind guest will occasionally be left off graphs. I am working with NOAA to resolve the issue. 12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed. 10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. |

GMZ300 Synopsis For High Island To The Matagorda Ship Channel Out 60 Nautical Miles Including Galveston And Matagorda Bays 1008 Am Cst Fri Jan 22 2021
Synopsis for high island to matagorda ship channel out 60 nm.. Patchy dense fog will be clearing this afternoon and evening as a weak cold front pushes into the gulf. With onshore winds returning on Saturday, conditions are expected to become favorable for sea fog once again for the rest of the weekend. Caution flags may be necessary on Sunday as moderate onshore flow develops ahead of the next disturbance. The cold front associated with this system will move through the coastal waters late Monday finally bringing an end to the sea fog threat.

AVIATION [12Z TAF Issuance].
LIFR to IFR conditions of 300-500 ft CIGs and patchy fog bringing visibility down to 2-3mi, and down to 1/2 at times, will continue through the morning hours today. A brief period of MVFR conditions when CIGs rise to 1500-2500 and only patchy fog will be possible later this afternoon into the early evening is possible, but a return to the IFR to LIFR conditions (from both low CIGs and visibility) will return late this evening and continue through Saturday morning, at least.

PREV DISCUSSION /Issued 411 AM CST Fri Jan 22 2021/.
SHORT TERM [Tonight Through Sunday].
The stationary front that sat across the area yesterday bringing about a cloudy, dreary day will slowly slide to the southeast today before stalling out again in the Gulf this afternoon. So, without this boundary to help initiate those those light showers we had yesterday, the chance of precipitation today will be lower. Mostly cloudy skies will continue today for most of the area, however some partly sunny skies may peak through across the northwestern counties as PWATs drop from around 1.4 inches to near 1.0 inch through the day. The chance of precipitation will remain low through Saturday morning, but increasing moist southerly flow ahead of a low pressure system entering the Central Plains will bring increasing POPs for beginning Saturday afternoon and overnight Saturday night.
Fog will remain a forecast concern through the short term with the chance of patchy fog, dense at times, continuing across the region. The fog threat will be highest during the overnight periods and for areas along the coast. Sea fog will also remain a possibility through the short term period as sea surface temperatures remain in the upper 50s to near 60 while dew point temperatures stay in the low to mid 60s. There may be some reprieve from fog this afternoon as the winds become northwesterly behind the slow moving boundary, but onshore flow picks up again on Saturday returning the high probability of sea fog.
Temperatures through the period will remain on the warm-side for the majority of the region. High temperatures this afternoon will be in the low the mid 70s with low temperatures tonight down into the mid to upper 50s. Saturday may be a few degrees cooler.
Fowler
LONG TERM [Sunday Night Through Friday].
A weak upper level disturbance coupled with weak warm air advection and a very weak surface trough will provide the area with a chance of showers on Sunday. The upper level disturbance will move NE in the afternoon and rain should diminish in the afternoon. Sea fog will remain a threat along the coast as SE winds will continue to advect warmer dew point air over the cooler shelf waters. A potent upper level short wave over the southern Rockies will pivot to the NE Sunday night into Monday and the trough axis associated with this feature will swing into North Texas and could provide enough lift to generate some additional showers over the northern third of the CWA Sunday night into Monday. A cold front will cross SE TX on Monday. There are still some timing differences between the faster GFS and the slower NAM/ECMWF. Not a lot of confidence in timing since the ensembles favor a faster fropa but the NAM generally handles frontal timing better than the GFS. Have leaned toward the faster GFS but this is subject to change. The front will have PWs of around 1.45- 1.55 inches and some weak jet dynamics so a band of showers and isolated storms should accompany the front. A developing offshore wind in the wake of the front should end the sea fog threat.
Another short wave trough will move across the central plains on Wednesday. Surface low pressure will develop over OK and move NE. As the low departs, a cold front will push to the E-SE amd move across the region on Wednesday afternoon. PW values only reach an inch or so not expecting much in the way of rain along the front. A 1035 mb high will drop into the central plains and ridge into Texas Wednesday night into Friday bringing dry weather and cooler conditions. Another potent short wave will move toward Texas next Saturday and this feature will bring a warm up in temperatures and rain back to the forecast. 43
MARINE.
Sea fog will remain a threat through the weekend as sea surface temperatures remain a few degrees below the dew point temperatures. However, a weak boundary will push into the Gulf waters this afternoon ushering in a weak offshore flow that will lower the chances for sea fog. This will only be temporary as east to southeasterly flow returns on Saturday bringing the return to the high threat of sea fog. This will persist through the rest of the weekend and into the first part of Monday. The onshore flow will increase to near caution flag criteria on Sunday ahead of an approaching disturbance. The associated cold front will push through the waters on Monday ending the sea fog threat for at least a few days as it ushers in drier air.
