DISCUSSION.

Updated for 06Z aviation discussion.

AVIATION.

MVFR conditions have developed west this evening, but VFR continues east. Guidance continues to indicate CIGS should decrease overnight as onshore flow increases. IFR conditions are possible for all terminals by late in the night. Light fog is possible, but vis restrictions should be minimal. MVFR conditions persist during the day Monday with a light to moderate onshore flow.

PREV DISCUSSION. /Issued 345 PM CDT Sun Apr 5 2020/

SHORT TERM (Tonight through Monday Night) .

Stalled frontal boundary over the northwest Gulf of Mexico is expected to drift westward back into Middle Texas coastal waters tonight and move inland on Monday. Moisture will steadily increase with the passage of the warm front with models depicting the precipitable water values increasing to 1.8 inches Monday afternoon. There will be a weak mid level disturbance that moves across south Texas on Monday. Lift associated with this feature should be enough to produce isolated to scattered showers on Monday with better chances for rain over the coastal plains. Air mass will become unstable by the afternoon leading to a slight chance of thunderstorms. Rain chances will be limited to the Brush Country Monday night where weak low level warm air advection will occur. Higher boundary layer moisture will lead to areas of fog for most inland areas late Monday night.

Tide levels remain about 1.5 feet above expected at Bob Hall Pier and has reached slightly above 2 feet this afternoon around high tide. Will continue Coastal Flood Advisory until 01Z tonight.

LONG TERM (Tuesday through Sunday) .

Southwest flow aloft will continue through most of the extended period as the region remains situated between a mid level ridge to the south and a developing upper closed low to the west over Baja California. Daily rain chances will exist Tuesday through Thursday as a series of disturbances disrupt the upper pattern and track across the area. With plentiful available moisture and weak to moderate instability in place, isolated to scattered convection is expected during the aforementioned time frame. As we head into the latter part of the week, the closed low will be transitioning into Desert Southwest and later on into the Southern Plains sending an associated cold front through the state and enhancing the convective potential. Timing of this front still remains uncertain at the time as current long range models solutions continue to diverge significantly. The GFS is the fastest solution pushing the front across the region on Friday, while the ECMWF holds the frontal passage until Saturday. With this in mind, have gone with the blended solutions until models come into better agreement, having the front push through South Texas on Friday, which leans towards the faster progression. Will continue to carry low-end PoPs over the weekend in case the front aligns better with the slower ECMWF solution.

Above normal temperatures can be expected through Thursday with highs in the mid 80s to the lower 90s and lows in the lower 70s. Cooler conditions will develop behind the front late in the week, with highs in the mid 70s to the mid 80s and lows in the mid 50s to the mid 60s.

Tides will remain elevated through the week and minor tidal overflow will be possible especially during periods of high tide Wednesday through Thursday. PETSS shows tide levels will be a little lower on Monday around time of high tide. Tides may be just below advisory levels on Monday.

MARINE .

Weak to moderate northeast flow over the Gulf waters will become easterly tonight as the frontal boundary drifts back toward the coast. Elevated seas will keep SCEC conditions over the offshore waters this evening. A weak to moderate easterly flow will occur on Monday as the warm front moves inland. Isolated showers will be possible Monday.

A weak to moderate onshore flow can be expected through Thursday. Winds will shift to the northeast Friday as a cold front pushes through the region. Showers and thunderstorms will be possible on and off through the period.

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.
