Area Forecast Discussion National Weather Service Austin/San Antonio TX 214 PM CDT Sun Aug 9 2020
SHORT TERM (Tonight through Monday Night). Upper level high pressure remains anchored across much of the Southern United States for the beginning of the week. This will continue the hot and mostly dry weather pattern for South Central Texas. Where the upper ridge is centered more over Texas, the surface ridge is situated across the Central Gulf of Mexico keeping sometimes gusty southerly flow off the Gulf at the surface. This will keep dew points and precipitable water values elevated, aid in the development of morning low stratus, and help push the sea breeze inland to the Coastal Plains.
High resolution models have so far today accurately depicted the shower and thunderstorm activity to the east of the area more from an Edna to Columbus to Brenham line as opposed to along the coast south of our area. This should keep most activity east of the I-35 corridor today, but as we have seen the last few evenings one or two showers and thunderstorms may approach parts of the I-35 corridor late this afternoon into the early evening hours. This will give a lucky few a brief shot at some rainfall. Models generally show less activity for Monday afternoon, and anything that does form should be more confined to areas of DeWitt and Lavaca Counties.
The other thing of note over the short term will be the temperatures. Highs today and tomorrow will range from the upper 90s to about 104 for most of South Central Texas, with the exception of the Hill Country where the mid 90s will prevail. Although dew points have been mixing out decently in the afternoon keeping heat index values relatively low, a few spots on Monday could hit or exceed the criteria of 108 degrees. These higher values will be isolated and more likely from Austin south to Seguin and along the Coastal Plains. With the more sporadic coverage of these higher heat indices combined with it being the climatological hottest week of the year will not go with a heat advisory at this time. This heat is more along the lines of a typical Texas summer.
LONG TERM (Tuesday through Sunday). Still no significant changes to the weather pattern in the long term forecast. The upper level ridge will remain over the southern US. This will suppress most convection and keep temperatures above normal. The low level flow will remain from the southeast. There will be low chances for showers and thunderstorms each afternoon and evening over the Coastal Plains. There is an even smaller chance that a few showers could make it as far north and west as I-35. High temperatures across South Central Texas will be from the upper 90s to near 105. Heat index values will be above 105 over most of the area except the Hill Country and Edwards Plateau. Heat index values look like they will peak Monday and Tuesday afternoons and we may need to issue heat advisories, but advisory level values may be too localized to warrant the product.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
