AVIATION. /00Z TAFS/ VFR conditions are expected across area sites through late tonight. MVFR cigs are expected around 10Z and 11Z Friday to affect KAUS, KSAT and KSSF and last through 15Z before VFR cigs return. Similar conditions are anticipated for KDRT around 13Z and last for a couple of hours before cigs lift back to VFR. Winds are forecast to remain from the southeast and south through Friday morning with speeds of 3 to 8 knots for the most part. Winds are forecast to remain from the southeast through Friday evening with speeds of 5 to 10 knots.
PREV DISCUSSION. /ISSUED 1257 PM CDT Thu Jun 4 2020/
UPDATE . See below for 18z aviation discussion .
AVIATION . Currently VFR at all terminals as morning stratus has mixed out leaving a scattered cumulus field. VFR conditions and south/southeasterly winds 10 knots or less are expected to prevail for the remainder of today. Another MVFR stratus deck is expected to develop around 10z Friday morning before improving to VFR once more by 16z Friday. There could be some patchy fog toward sunrise Friday, but for now have kept VSBYs at P6SM at all terminals.
PREV DISCUSSION . /ISSUED 555 AM CDT Thu Jun 4 2020/
UPDATE . Patchy fog has developed east of I-35. Have updated to include patchy fog through mid morning. Temperatures and dewpoints are also a little warmer and have trended those parameters warmer through mid morning, as well.

SHORT TERM (Today through Friday) . The mid and upper level ridge centered over Chihuahua state of Mexico gradually expands to western Texas today and the southern Plains Friday. Subsidence, capping warm mid level temperatures, and drier air aloft will accompany this expansion keeping POPs out of the forecast. However, cannot rule out an isolated shower and maybe a thunderstorm or two southeast of a Kenedy to Cuero to Speaks line during the afternoon hours along the seabreeze at peak heating. The warming trend continues with temperatures rising to above normal.
LONG TERM (Friday Night through Wednesday) . High pressure ridge over south central CONUS, with upper level troughs on either side will continue to shift eastward out of southwest Texas and southern New Mexico towards the Mississippi River Valley throughout the weekend. By this time, what currently is Tropical Storm Cristobal will have begun its approach toward the central Gulf Coast. The upper level ridge will dominate our weather pattern here in south central Texas with dry conditions and a warming trend taking hold.
Current model consensus keeps Cristobal east of the region, while there still is plenty of uncertainty will this system and still early to make any final conclusions about its track, if it were to remain well east of the region, large scale subsidence would take place over the area. This would lead to very warm temperatures, potentially record setting heat for the Monday/Tuesday timeframe. Latest Euro run has temperatures ranging from 101-103 over the I-35 corridor to 108 for Del Rio. Although above normal rainfall has fallen over much of the region, hot and dry conditions will persist through much of the long term with minRH values falling below 20 percent out along the Rio Grande on Tuesday and Wednesday. Fire weather could be of concern during this time.
As the upper level synoptic pattern continues to cycle eastward, a trough will traverse the northern and central plains late Tuesday and models want to bring a backdoor front in Wednesday, giving the next shot at some rain. We will have to see if the front is persistent in the following model runs as well as what is to come of Cristobal.

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.
