Area Forecast Discussion National Weather Service Houston/Galveston TX 1201 AM CDT Sat Aug 8 2020

AVIATION [06Z TAF Issuance]. Very minor changes, persistence is the plan with some patchy fog at CXO/LBX possible and even a brief stint of MVFR ceilings near CLL at sunrise. Isolated to widely scattered showers and isolated thunderstorms along the seabreeze. 45

PREV DISCUSSION /Issued 927 PM CDT Fri Aug 7 2020/.

SHORT TERM [Sunday Through Monday Night]. Showers have ended and skies are mostly clear to clear with just a little streak of cirrus coming in on northeast flow aloft. Overnight expecting above normal temperatures and a good chance that Hobby will only fall to 80 degrees. So record high minimum of 79-2017 degrees is in jeopardy there. Spotty showers possible toward morning near the coast still looks on track. Daytime heating should help with the development of isolated showers and thunderstorms during the peak of heating along the I-69 corridor south and southwest of Cleveland.

45

LONG TERM [Sunday through Friday].

Low chance of rain is anticipated through early next week across Southeast TX, increasing mid week through the end of the work week.

Pulses of low level moisture will move into the local area from the Gulf and combine with temperatures in the mid to upper 90s (convective temperatures in the lower 90s) and CAPE values of 2000- 3000 J/kg. This would typically be enough to produce some shower and thunderstorm activity for our local area on a regular summer day; However, the presence of the mid to upper level ridge over the region will likely inhibit some of the shower and thunderstorm development. Even with the ridge aloft, environmental conditions along the lower levels may be able to produce some isolated to scattered activity particularly along the seabreeze boundaries each afternoon as the diurnal heating peaks. On Monday, slightly lower chances of rain are expected in response to drier air moving into the area. Although some of this drier air remains in the area Tuesday, PoPs were kept slightly higher than Monday's (albeit 30% or less), since the ridge will begin to retreat to the west in response to a shortwave moving eastward into the Great Plains, reaching the northern TX and OK region. By Wednesday, models show PW's reaching 2.0 inches across portions of the CWA. Another shortwave will move into northern TX Thursday into Friday, keeping the ridge to the west, and thus with the increase in moisture, will allow the local weather pattern to transition to a more summertime one through the end of the work week.

High temperatures each day will be in the mid to upper 90s for most of the CWA, with the hottest temperatures likely to occur over areas north of I-10. Low temperatures each night will be in the mid to upper 70s inland and in the low 80s along the coasts. Heat indices will be in the mid to upper 100s Sunday through mid week, and some areas could have indices reaching Heat Advisory criteria for a few hours in the afternoons. Make sure to plan ahead to protect yourself and your loved ones, including pets, if you are to spend time outdoors or in areas with poor ventilation. It is recommended to practice Heat Safety during these next several days.

MARINE.

High pressure over the eastern US and low pressure over the Southern Plains will maintain a light onshore flow through the weekend. The area of high pressure will shift toward the northeast Gulf by early next week. A very typical summer like pattern is expected at that time with slightly stronger winds at night over the Gulf waters and lighter winds during the day and stronger daytime winds over the bays and lighter winds at night. 43

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.
