Area Forecast Discussion National Weather Service Houston/Galveston TX 639 AM CDT Fri Aug 14 2020

AVIATION [12Z TAF Issuance].

Patchy fog and low clouds/stratus have resulted in MVFR to occasional IFR conditions mainly across the Brazos Valley, impacting KCLL and KUTS terminals. Fog and stratus are expected to lift by 14Z. Otherwise, VFR conditions are expected through the period. Light southwest winds will transition to the south late this morning through the evening hours.

PREV DISCUSSION. /ISSUED 356 AM CDT Fri Aug 14 2020/

SHORT TERM [Today through Saturday Night] .

High confidence in the heat still dominating the region today. North to northwest flow aloft persists across the region due to the anomalous mid to upper level ridge centered over the southwest CONUS. 850 hPa temperatures will range in the lower 20s Celsius this afternoon; resulting in another hot day. The combination of warm and humid south to southwest flow at the surface will lead to afternoon heat indices in the 105-110 range. Isolated brief heat index values up to 112 will be possible. Heat Advisories remain in effect for the entire forecast area.

Saturday will still be another hot day (or hotter than previous days). 850 hPa temperatures are progged to be in the lower to mid 20s Celsius. In fact, this is falling outside of climatological range with NAEFS and ENS values in the 99th to Max range at 850 hPa. It won't be a surprise that this will lead to heat indices from 105 to 110 degrees; therefore, have extended the heat advisory through Saturday evening.

LONG TERM [Sunday through Friday] .

The heat looks to continue on Sunday as the ridge holds strong across the southwest CONUS and surface dewpoints remain in the upper 70s. NAEFS, ENS and GEFS continue to suggest values in the 99th percentile; therefore, have included high temperatures in the upper 90s to around 100 degrees for Sunday.

The heat will begin to dwindle after Monday with temperatures ranging close to average. There is a slight chance for shower and thunderstorms late Sunday afternoon in response to weak embedded shortwaves traveling along the eastern periphery of the ridge aloft. Weather pattern begins to change after Sunday evening. The aforementioned upper-level ridge remains strong but begins to shift northward by the beginning of next week as a wave and associated front track southeastward across the southern Plains. Uncertainty arises in terms of timing and strength of this frontal boundary across our region due to differences between models. As of now, have increasing rain and storm chances Sunday night into Tuesday. Weather pattern looks more typical for this time of year by the middle of next week with near seasonable temperatures and showers/storms due to daytime heating and convergence along the seabreeze.

MARINE . Surface high pressure over the northern Gulf of Mexico continues to dominate the region, maintaining light to moderate south to southwest winds. Seas will generally be from 1 to 2 ft through the weekend. Pattern changes early next week with the passage of a a weak cold front. Showers and thunderstorms will be possible along with a shift in wind direction, mainly on Monday. East to southeast winds return by mid-week.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
