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. VFR and light winds continue for the remainder of today and this evening before low ceilings and fog develop near the coast toward midnight. This layer will expand from E-W and should reach LRD by daybreak. Highest confidence in IFR ceilings and/or visbys remains over the eastern terminals late tonight and continuing through all day Saturday, with some drizzle possible by late morning as this stratus grows deeper.

PREV DISCUSSION. /Issued 359 AM CST Fri Jan 22 2021/

SHORT TERM (Today through Saturday) .

The boundary just offshore has nudged just slightly north and east overnight and is currently just draped right along the coast if not pushing inland across the Northern Coastal Bend where a southerly wind is present. Sea fog has developed along the coast as warm moist air flows over the cooler shelf waters. Visibilities have been fluctuating throughout the night from roughly 1-3 miles per the vis sensors along the coast. Further inland, winds are light and variable with patchy fog and low level stratus present. Looking further north on satellite and radar, a shortwave is pushing across Central Texas with showers in place across the Hill Country. An associated weak boundary/surge of high pressure will advance south early this morning and will move offshore around sunrise. A few isolated showers will be possible as this boundary moves through, mainly across the Coastal Bend and over the waters. Drier air will lag behind the boundary by a couple of hours but once this drier air arrives, visibilities will improve across the region. Despite the passage of a weak front this morning, temps will warm into the low 80s out west to mid 70s along the coast as a result of downsloping winds.

This morning's boundary will stall offshore this evening and push back as a warm front overnight and into Saturday. As a result, another round of sea fog and low level stratus is expected as isentropic lift kicks in. Temps will be a few degrees cooler tonight as the slightly drier airmass is in place. Another reinforcing surge of high pressure will move south across the state during the day. If it can make this far south before the warm front advances too far north, we may see lows a couple of degrees cooler than expected across the Northern Brush Country. For Saturday, the warm front will advance north through the with low level stratus spreading across the region. Trended on the cooler side of guidance for highs as dense stratus will keep us cool with temps in the low to mid 70s. Model soundings show a fairly saturated column up to roughly H85. Therefore, isolated light showers/drizzle are possible on Saturday across the region.

LONG TERM (Saturday Night through Thursday) .

Southerly low level flow increasing to 25-30 knots Saturday night will bring in deeper moisture to the coastal plains with precipitable water values rising to around 1.5 inches Sunday morning. Isolated to scattered streamer showers will be possible over the coastal plains Saturday night into Sunday with the best chance for rain in the Victoria Crossroads. Advection fog will continue along the coast Saturday night into Sunday morning. Southwest flow aloft will maintain strong mid level inversion to maintain strong cap over the region inhibiting thunderstorm development.

Upper low over the Desert Southwest Sunday morning will open into a wave as it moves into the southern plains Sunday night. This will send a cold front into the region early Monday morning. There will be enough instability over the Victoria Crossroads in advance of the front with lift along the front and weakening convective inhibition to warrant mentioning a slight chance of thunderstorms Sunday night. Drier air will move into the area behind the front Monday. Surface high will be over south Texas Monday night leading to cooler lows.

Models are in agreement with another upper low moving into the Great Basin Monday and Monday night. This low will also weaken into a wave as it kicks out Tuesday with system moving into the southern plains a little more to the north. A weak trough will be over the northwest Gulf of Mexico Tuesday night into Wednesday that will limit moisture return. Could see isolated showers affect the coastal plains Wednesday ahead of the next front. It will be dry and cool behind the front Wednesday night into Thursday.

MARINE .

Isolated showers have developed along the coast early this morning. Showers will remain possible through the morning as a weak boundary moves offshore. Ahead of the boundary, sea fog will continue to reduce visibilities to near 1 mile or less at times as warm moist air flows over the cooler shelf waters. A light offshore flow will develop this morning as the front moves offshore. Winds will shift back to the east-southeast this evening as the boundary moves back north as a warm front. Sea fog is expected to develop once again tonight and persist through the day Saturday. Isolated showers will also be possible throughout the day. A weak to moderate southeast flow will occur Saturday night with sea fog lingering over the bays and near shore waters until Sunday morning. Onshore flow will increase to moderate levels/SCEC Sunday and reach SCA levels Sunday night over the Gulf waters. Isolated to scattered showers will be possible Saturday night through Sunday night. A cold front will move through Monday morning providing a weak to moderate northerly flow through Monday night. A weak to moderate northeast flow is expected Tuesday. A weak trough will form over the northwest Gulf of Mexico Wednesday with isolated showers possible. Another front will move through the area Wednesday night with a moderate offshore flow through Thursday.

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