Synopsis for the middle texas coastal waters -
winds will remain weak at 10 knots or lower today with the winds shifting to the southeast by tonight. Weak onshore flow Sunday strengthens late in the day, making the bays a bit choppy. Weak to moderate onshore flow Monday. A series of upper level disturbances expected to move across the plains will contribute to generally moderate onshore flow Tuesday through Friday.

Key Messages:
- A Elevated risk of heat related impacts from dangerous heat today and Sunday across most of South Texas
A 500 mb ridge is just to the west of the south Texas with the axis running roughly from TOP to AMA to ELP and south into northern Mexico. The ridge is expected to move east into south Texas by the end of the day on Sunday. At the sfc, there is a large, sprawling sfc high that reaches down into the Coastal Bend from just off the east coast of FL. This set up will keep the region precipitation free, and warm. Of course, it's the warmth that is of concern as we head into this week's forecast. For today and Sunday, the high temperatures will be have roughly the same high temperatures with around 90 along the Coastal Bend to around 100 along the Rio Grande Plains. The moisture is the concern with the heat, which will produce heat indices above 100 again today and Sunday, but will remain below 110F both days. The new heat risk map put together by the NWS and CDC shows minor to moderate risks of heat related impacts. There could be some heat related issues, but for most, it will just feel hot.
The only other issue to watch is fog. With the rain from today, our normal fog prone areas (ALI and VCT) will have fog, as the fog has already formed around the Victoria Crossroads and the eastern part of the Brush Country around Alice. The guidance (NBM) would suggest that the lowest VSBYs would be toward 12z/Saturday, but considering the past week, when we have had fog, it would form and then dissipate with no noticeable affects by 12z. So will have to monitor it and decide if a SPS or an Advisory will be necessary. Saturday night/Sunday looks similar as the light winds, clear skies and residual moisture looks like it there would be a 50% chance of VSBYs<5 miles Sunday morning as well.

Key Messages:
- A risk of heat related impacts Monday through Thursday across the Brush Country and southern Coastal Plains
- Heat impacts may worsen Friday over portions of the Brush Country
NWP model runs continue to predict the development of a warmer airmass over the region beginning Monday, manifested by an upper ridge that builds over the region. The upper ridge is predicted to persist and remain quasi-stationary during the remainder of the period. A progressive pattern is expected to remain over nearly all of the CONUS, except for southern Texas, with upper disturbances moving close yet generally remaining north of the CWA These disturbances will contribute to persistent onshore flow and increasing moisture over the region during the period. The GFS/ECMWF predict PWAT values to remain above normal over the CWA during the period. Subsidence associated with the upper ridge will contribute to an inversion which will suppress convection, moisture notwithstanding. Thus, no significant precipitation expected during the period. The combination of heating and greater near surface moisture will increase maximum Heat Index values over the CWA WPC continues to predict a 40-70 percent chance that the maximum Heat Advisory threshold of 110F will be met over the Brush Country and southern Coastal Plains Monday through Thursday. The GFS/ECMWF predict PWAT values to increase even further Friday, potentially resulting in even higher maximum Heat Index values. WPC predicts a 40-70 percent chance that the Excessive Heat Warning threshold of 115F will be met Friday over portions of the Brush Country.

VFR conditions are expected to prevail across much of S TX tonight. However, brief periods of MVFR CIGs across ALI, CRP and VCT will be possible overnight into early Saturday morning. VSBYs are also expected to lower to MVFR/IFR for these areas toward early Saturday morning between 09-14Z due to patchy fog. The SREF is showing the probability of visibilities less than 1SM is between 20- 50%, mainly from ALI to VCT. VFR conditions are expected by mid morning Saturday with much less cloud cover due to a ridge building across S TX. Light and variable winds tonight will gradually shift around to the east and southeast through the day Saturday.
