Area Forecast Discussion National Weather Service Austin/San Antonio TX 329 AM CDT Sat Aug 8 2020

SHORT TERM (Today through Sunday). There is not much change in the overall weather pattern with an upper ridge dominating the short term weather. There will not be much change through Sunday as hot temperatures will prevail across the region with only the slightest chances of getting an isolated shower or storm to fire mainly from the afternoon heat and some sort of convergence. Normally that happens along the seabreeze to the SE. Yesterday it looked like a very small isolated shower was able to form along a cloud street across portions of Bexar County. Unknown if that type of isolated convection will once again occur that far inland, so the only pop being carried is along the SE zones . banking on some weak seabreeze convection. Sort of grasping for straws with this as the overall pattern, poor soil moisture, and fairly low PW and dewpoints are not allowing for much in the way of development. The mixing out of lower dewpoints will keep the area below any sort of oppressive heat and advisories. A decent surface pressure gradient will at least keep a moderate southerly breeze in place . getting gusty in the late afternoon and evening hours. Have seen an uptick in grass fires as well . and that threat will likely increase as the persistent hot, dry, and sometimes breezy pattern holds strong.

LONG TERM (Sunday Night through Friday). Mid and upper level ridging stretching from the desert southwest into the Gulf of Mexico will remain the dominant weather feature of interest through the upcoming work week. With this pattern intact, all areas can expect a continuation of above normal high temperatures, with overnight low temperatures at or just above normal. Overall, the NBM numbers appear fairly reasonable, but we did opt to nudge high temperatures upward in urban areas. We do expect most locations to remain dry for the upcoming week. However, given the above normal temperatures and some afternoon convergence along the sea-breeze, we will keep a low chance for showers and thunderstorms in the forecast near the coastal plains and Highway 77 corridor. Some of the medium range models suggest the mid and upper level ridge may weaken slightly across our region on Thursday or Friday. However, without much model support, we will stay with more of a persistence forecast which equates to hot and mostly dry weather continuing across south central Texas.

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.
