Synopsis for the middle texas coastal waters.. A weak to moderate onshore flow will persist overnight. Increasing moisture and isentropic lift will bring scattered showers to the region tonight. Rain chances will increase on Sunday and Sunday night as a cold front moves through south texas and into the coastal waters. Anticipate numerous showers with isolated Thunderstorms on Sunday and more numerous showers Sunday night. Winds will gradually transition from a weak to moderate southeast flow Sunday to moderate northeast flow Sunday night as the front enters the coastal waters. A coastal trough will develop Monday and contribute to additional scattered to numerous showers, along with weak to moderate northeast flow. The trough will move farther offshore Tuesday and decrease the chance for precipitation, and north to northeast flow will increase to moderate levels. The coastal trough will redevelop Wednesday in response to an upper level disturbance and increase the chance for shower activity, along with weak to moderate east to northeast flow. As the upper system moves east, drier conditions will develop Thursday and decrease the chance for rainfall.

Aviation Cigs will gradually decrease this evening and tonight for all sites becoming MVFR to ifr. With increasing moisture expect some moderate vis restrictions to develop as well. Light showers will be possible through the night. A cold front currently in north texas will move southward through the night and is expected to be to victoria by mid-morning and through other sites by mid-day. Generally MVFR CIGS are expected behind the front with the chance for showers continuing. Gusty north winds will also develop behind the front. Previous discussion issued 419 pm cst Sat nov 17 2018 short term (tonight through Sunday night)... tonight moisture will continue to increase across the region with a moderate onshore flow. A few light showers and sprinkles have already begun developing across the coastal bend and coastal plains late this afternoon. Isentropic upglide will produce scattered showers overnight, with coverage increasing across the coastal bend into the victoria crossroads after midnight. Additionally, patchy fog to areas of fog may develop late tonight into early tomorrow morning. By early Sunday morning a cold front will be positioned across the hill country. A cold front is still expected to push south and through the region during the day tomorrow. Confidence is not too high on the exact timing of the fropa, as the NAM continues to surge the front more quickly through the region and the coastal waters, while the GFS and ecmwf bring the front through more gradually throughout the day. Leaned towards a slightly slower solution, though still have the front moving through the northern counties by 18z and to the coast by around 00z. Anticipate the front to then stall over the coastal waters, with a coastal trough then developing late Sunday night into early Monday morning. Scattered to numerous showers will develop over the region tomorrow morning, with the highest coverage over the coastal waters and coastal bend. A few thunderstorms may develop over these areas, but the majority of the activity should be showers. Overrunning showers will persist through the afternoon and into tomorrow night with the boundary positioned over the coastal waters. Temperatures on Sunday are a bit tricky, with highs being entirely dependent on timing of the frontal passage. Anticipate highs will be reached closer to noon in the mid upper 60s across the northern cwa, and in the low 70s to the south and along the coast, with temps falling through the afternoon. If the solution were closer to the swift timing of the |
nam though, the high temperatures across the south and coast could be a bust. Lows tonight will be in the lower 60s, with tomorrow night cooler in the upper 40s to mid 50s. Long term (Monday through Saturday)... concur with the deterministic gfs ECMWF which predicts a coastal trough to develop Monday, likely in part due to a weak upper disturbance (identified with 700-300mb q-vector convergence.) anticipate at least scattered convection in response. Tuesday, concur with the gfs ECMWF with respect to the movement of the surface trough offshore (yet ECMWF slower with this movement.) for Tuesday night Wednesday, in response to another yet stronger upper disturbance, the coastal trough redevelops. The combination of the upper surface forcing likely to generate scattered convection by Wednesday. Thursday, the upper disturbance moves east of the region (gfs ECMWF gfs ensemble mean) resulting in drier conditions. Although the GFS predicts pwat values to be above normal Friday Saturday, high condensation pressure deficits are predicted to remain over the cwa, and do not anticipate significant precipitation. Marine... onshore flow will persist overnight with a chance for showers. A cold front will move into the waters overnight and stall. Scattered to numerous showers will be possible Sunday and Sunday night. A coastal trough develops Monday and contributes convection, moves offshore Tuesday in response to the upper pattern, resulting in a decreasing chance for convection and scec wind, then moves back to the coast Wednesday in response to an upper level disturbance and thus increasing the chance for convection. Drier Thursday as the upper system moves east. Isentropic lift weak condensation pressure deficits may contribute to isolated showers patchy light rain Thursday Friday.

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. |
