DISCUSSION. See Aviation section for 00Z TAFs.

AVIATION. Gusty southerly winds will continue for a couple more hours. Expect low stratus to develop over the inland coastal plains late this evening with MVFR ceilings/vsbys. The southerly low level jet will remain from 30-40 knots over the coastal plains overnight. Ceilings/vsbys will fall to IFR around 08Z but not expect fog to become dense as low level flow will be from 30-40 knots. Low level flow will be weaker over the Brush Country and expect low stratus to be LIFR levels from 09-14Z with vsbys from MVFR to IFR. Ceilings will improve to MVFR and fog dissipate as low level flow veers to southwest and west with approach of the pre-frontal trough. Conditions will improve to VFR in the afternoon over the Brush Country as the cold front moves through. MVFR ceilings will hold over the coastal plains as the front moves into the Gulf waters late afternoon and north winds become gusty.

PREV DISCUSSION. /Issued 340 PM CST Sun Dec 15 2019/

SHORT TERM (Tonight through Monday Night) .

A sea breeze can be seen on radar moving inland across the Coastal Bend this afternoon. This is due to the very warm temperatures across S TX. A 40KT LLJ on this morning's upper air sounding has shifted east and weakened. This has resulted in winds being a few knots lower than anticipated, but still a breezy day. Sunny skies this afternoon will become mostly cloudy tonight with low level moisture trapped beneath a strong capping inversion. Models show the better chance for fog to be across the western CWA late tonight, where surface winds will be lighter and less cloud cover. Although, patchy fog is expected across the Coastal Bend and Victoria Crossroads, but should be light.

A strong cold front is progged to move across S TX through Monday morning, reaching the coast by early afternoon. The stronger winds and colder/drier airmass will be lagging behind, but will definitely be more noticeable by Monday evening. Monday's highs will be well above normal, followed by much cooler lows Monday night.

LONG TERM (Tuesday through Sunday) .

Post frontal airmass continues to settle into the region on Tuesday with strong CAA continuing. High temperatures will likely top out in the 50s for most areas. Breezy conditions will make it feel like the 40s through at least mid-day . but at least skies will be mainly clear to give the impression it's a bit nicer. Winds will gradually subside through the afternoon and evening as the surface ridge sinks into the region. This will set up a very cold night for Tuesday night with freezing temperatures still appearing a possibility for northern areas. NAM model, which is typically a better performer in post frontal airmasses has warmed just a bit from initial temps on the 00Z run, and is now very similar to the NBM model. Have gone pretty close to both of these, and would require a freeze warning as we get closer. Cold temperatures continue Wednesday, but winds will shift more to the east and southeast by Wednesday evening and overnight to keep temps up a few degrees warmer than Tuesday night. Moisture return will be limited before our next weak front moves through on Friday . PWATs increasing only to just above 1 inch. Will keep PoPs at only slight chance Thursday night through Friday night, and mainly in the east. Temperatures warm a bit Thursday and should not be affected much by this weak front . expecting highs around 70 by Friday through the weekend.

MARINE . Moderate to strong southerly flow is expected tonight and a Small Craft Advisory is in effect for the southern bays and nearshore waters until 7 pm this evening and the offshore waters until Noon Monday. Patchy fog will be possible near the coast and adjacent bays overnight tonight. Winds will relax somewhat through early Monday afternoon, then a strong cold front will move through the area Monday afternoon delivering strong northerly winds by late afternoon into early Monday evening. A Gale Watch is in effect Monday evening through Tuesday morning for possible Gale conditions. Small Craft Advisory conditions will then likely linger through Wednesday morning. Weak to moderate onshore flow will resume Wednesday night and Thursday.

Scattered showers and thunderstorms are expected on Monday with the front.

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.
