SHORT TERM (Today through Friday).

Patchy dense fog will be an issue this morning across the southern Brush Country due to light winds and dry air advection over a moist boundary layer. Latest HBV observation measured visibilities <1/4 mi and nighttime microphysics satellite enhancement was picking up on a developing area of fog. Expect patchy fog to potentially expand across the inland Coastal Plains from ALI-BEA-VCT by sunrise. Fog should dissipate by around 14z. Expect deepening moisture throughout the day today with PWATs climbing to 1.9". However, only isolated showers/storms are expected along the sea breeze as ridging/ subsidence increases aloft. Patchy fog is possible again tonight due to light winds and mostly clear skies. Coverage of precipitation will be higher on Friday as a deeper surge of gulf moisture moves in along the mid TX coast with pwats around 2.3". Mid/upr level support isn't great given the ridge aloft, but still expect scattered activity along the sea breeze. Can't rule out a tropical funnel or two given the continued weak flow. Temperatures will be seasonal with heat indices in 105-109 range most areas today and Friday.

LONG TERM (Friday Night through Wednesday).

An upper level high over the Great Plains builds southeast this weekend before retreating back towards the north west as a deepening trough over the east coast expands southwestward early next week. Meanwhile, a low in the Southwestern Gulf moves west over Mexico bringing an inverted trough near the Texas coast on Sunday.

As the aforementioned trough deepens into east TX, a back door cold front will surge southward through the state. Guidance has picked up more on this feature over recent runs and the GFS has it moving towards us Monday into Tuesday before stalling. Meanwhile the Euro has it further east of our area. It's possible it could make it through our CWA Thursday/Friday but confidence is too low at this time.

Isolated showers and thunderstorms are possible Saturday but mainly along the seabreeze in response to the inverted trough. Sunday and Monday are expected to remain dry. Isolated coverage will spread across South Texas with scattered coverage for the eastern portions starting Tuesday through Thursday in response to the proximity of the trough promoting general weakness aloft.

Surface heating combined with increasing PWAT's around 1.80-2.00" will raise heat index values to SPS/Advisory levels each day through the period. It is advisable to stay in an air conditioning as much as possible and caution should be exercised whenever outdoors as heat indices exceeding 110 are possible. Also, remember to hydrate.

MARINE.

Weak to moderate onshore flow will dominate the period. Isolated to scattered showers and thunderstorms are possible Today through Saturday. Dry conditions are expected Sunday and Monday. Then isolated to scattered showers and thunderstorms will be possible Tuesday and Wednesday of next week.
