Synopsis for high island to matagorda ship channel out 60 nm.. East winds will gradually become southeast by mid week as high pressure over the great lakes moves east. Southeast winds will persist through Friday and then begin to back to the northeast as low pressure develops in the central gulf. Mariners are urged to keep up with the forecast this weekend as a tropical disturbance over the yucatan moves north into the central gulf of mexico.

Area Forecast Discussion National Weather Service Houston/Galveston TX 1104 PM CDT Mon Jun 1 2020

AVIATION [00Z TAF Issuance].

VFR conditions across the CWAs as the airmass begins to stabilize. Some mist in the SGR/LBX flying area could bring conditions to MVFR but lower visibility should stay west outside of the CWAs. Northern ceilings will be around 5000 to 6000FT AGL and increase to the mid levels towards the coastal areas. Winds will stay light overnight and increase tomorrow morning.

Chances of showers and a small area of thunderstorms are expected tomorrow mainly in the northern CWAs and showers elsewhere. Most development of convective activity will start between 21Z and 22Z due to higher convective temperatures and overall cloud coverage. By 00Z tomorrow, the short wave effecting the area will move east and skies will begin to break out across the CWAs.

BGK

PREV DISCUSSION /Issued 758 PM CDT Mon Jun 1 2020/.

SHORT TERM. Quick update to lower rain chances this evening for much of the region through 3 am then may see some increasing chances southwest and west. Skies will be mostly cloudy to cloudy but some of the mid level clouds may depart with s/w leaving mostly high thin clouds and scattered lower clouds. 45

LONG TERM [Wednesday Through Monday].

Heading into the middle of the week, expect little change to the overall pattern with warm and humid conditions persisting as we head into the weekend. With surface high pressure continuing to remain in place across the southeast US coast and weak ridging aloft, light to moderate onshore winds should continue to supply a steady influx of low-level Gulf moisture to SE Texas. This should keep PWAT values within the 1.75 to 2.0 range through Friday. As we've seen over the past few days with a similar pattern in place, differential heating and the subsequent northward propagation of the resultant sea breeze boundary should allow for scattered showers and thunderstorms to develop during the afternoon hours. Have continued to maintain 15-30% PoPs through Friday as a result. High temperatures will remain fairly close to June climatological normals through the duration of the forecast period, with most areas continuing to see values in the low 90s. Dew points in the low to mid 70s may result in some heat index values reaching the 100s by the end of the week, so be sure to exercise caution if you're planning any outdoor work or exercise.

We continue to monitor development in the tropics, with a significant amount of uncertainty entering the forecast picture as we head into next weekend. The National Hurricane Center will begin to issue advisories on a disturbance (formerly known as Tropical Storm Amanda in the Pacific Basin) over the Yucatan Peninsula later this afternoon, which will be designated as Tropical Depression Three. Global models, although showing significant variability in the track and intensity of the storm, place its center of circulation in the Central Gulf by the end of the weekend. With a great deal of divergence amongst the global deterministic and ensemble solutions, it's too early to discuss any potential impacts to SE Texas due to low confidence. The eventual path that the storm does take is likely to hinge upon the placement and amplitude of the upper ridge over the weekend, with the GFS currently favoring a more progressive solution and thus a more eastward storm track. ECMWF, on the other hand, favors a slower solution which results in a westward turn in storm motion as the system approaches the Gulf coast. Regardless of the impacts of this particular storm, we do encourage everyone to have their hurricane plans in place and emergency kits prepared for hurricane season, which did officially begin today.

MARINE.

Broad low pressure over the southern Gulf and high pressure over the eastern seaboard will maintain an easterly flow through Wednesday. Low pressure will develop over the central plains Wednesday night and winds should veer to the SE. The broad area of low pressure will become much better defined and this feature will begin to move north. Winds will once again back to the E-NE and gradually increase as the gradient tightens. Conditions look favorable for a tropical storm to develop and NHC will initiate advisories on TD 3 at 4 PM CDT. Where the TD goes over the weekend will obviously have a huge impact on marine winds/waves. Still some inconsistencies between model solutions but there is a growing consensus that a Tropical Storm will move into the central Gulf by Saturday and toward the LA coast by Sunday AM. A blocking ridge will shunt the system westward toward the Texas/LA coast Sunday night/Monday. Have remained conservative with wind speeds and waves for now until models come into better agreement. Mariners and marine partners should keep up with the latest forecasts as deteriorating conditions are expected Friday through next Monday. 43

TROPICAL.

The National Hurricane Center will begin to initiate advisories on Tropical Depression Three, currently located in the Bay of Campeche, this afternoon at 4PM CDT. As discussed above, significant uncertainty in the eventual track of this system amongst model guidance sources has kept forecast confidence fairly low at this time. With today marking the beginning of the official Atlantic Hurricane Season, it nonetheless is a time to remain vigilant of tropical weather activity and to have a hurricane plan in place with an emergency kit prepared.

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