AVIATION. Currently wind gusts up to 40 mph and occasional lightning is possible at the San Antonio sites. These hazards are expected to persist for the next half hour or so with vicinity showers persisting till later this evening. Wind and lightning threat has cleared AUS and never existed for DRT. VFR ceilings will persist overnight and winds will relax to at or below 5 knots. Besides convection this evening which should subside by 01Z for San Antonio terminals, no other hazards expected through the period.

UPDATE . Quick update to pull slight chances for showers and storms further to the southeast, passed the I-35 corridor. Also retrended temperatures, mainly for the Hill Country where storms that moved through have dropped temperatures into the mid to upper 70s. Convective allowing models still dissipate this activity as it moves over the I-35 corridor this evening but wanted to extend PoPs further to the southeast with new convection still firing over Bexar and northern Medina counties at this time.

SHORT TERM (Tonight through Tuesday Night) . Visible satellite imagery depicts a broad area of of mid-to-upper level clouds associated with a weak shortwave that is expected to fall apart as it traverses our area through tonight. A few light showers on radar as of 18Z over western Val Verde County may or may not be reaching the ground, but CI is ongoing with one cell over San Saba County as of this writing. Additional development of showers and isolated thunderstorms is expected this afternoon over the Hill Country, shifting SE through late evening before diminishing.
With a decent amount of low level dry air, DCAPE values near to above 1200 J/kg are in place, and thus any storms that do develop would have the potential to produce gusty winds. However, this threat is relatively low at this time and we remain in an SPC general thunder outlook area. The current forecast calls for precipitation to end by 03Z, however there are signals in the NAM and GEFS for some lingering activity to continue until closer to sunrise. Forecast updates may be needed if trends continue in that direction.
Clouds should gradually diminish with the weakening of the H5 vorticity axis overnight. Expecting overnight lows in the 70s, with a couple spots across the Hill Country maybe reaching the upper 60s. As upper level ridging to our west begins to slowly shift in this direction, calmer conditions are expected for Tuesday, with highs ranging from about 96 to 104. Heat indices should max out around 105.
LONG TERM (Wednesday through Monday) . The beginning of the long-term forecast will be hot and dry as upper level ridging builds in from the west. Highs will likely top out in the upper 90s to 103 degrees on Wednesday and Thursday with heat index values up to 107 degrees in the Coastal Plains. The ridge is expected to remain in place through the end of the forecast period keeping dry conditions in place for most of the area. However, models are progging enough low-level moisture beginning Friday across the extreme southeastern CWA for a slight chance of afternoon showers or storms. This diurnally driven rain chance should continue through the weekend and into Monday for the previously mentioned area. Otherwise, highs this weekend will remain in the upper 90s to near 103 degrees with the higher temperatures in the Rio Grande Plains. Lows will remain in the 70s.

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.
