SHORT TERM
(This evening through Saturday Night)
Issued at 317 PM CST Fri Dec 1 2023

SHORT TERM

At 2PM, surface obs, satellite imagery and surrounding radar were showing a weak cold front extending along the coastal counties/islands and a cluster of showers and thunderstorms developing over the Coastal Bend/Matagorda Bay. This activity over the Gulf waters is related to a weak sfc coastal low and weak mid- level shortwaves. The interaction of the frontal boundary, sfc coastal low and shortwaves aloft will result in scattered showers and thunderstorms this afternoon and early evening. The best rain/storm chances will be south of I-10. Rainfall totals up to 1.0" can be expected with locally higher amounts possible along the Islands. The front will stall along the coast tonight, potentially increasing the chance of fog through early Saturday morning.
Lingering low-level moisture and light winds will also allow for patchy fog further inland through early morning. Dense fog looks more likely across the coastal counties/waters continuing as early as this evening.

Weather conditions become more stable on Saturday as the front finally moves further offshore and a drier airmass begins to filter in from the northwest with a secondary/reinforcing boundary during the day. Skies will become partly sunny at most inland locations by the afternoon and along with light northerly winds, diurnal heating and a forecast of warm 850 mb temperatures (low teens degC), this will result in highs mainly in the 70s.

LONG TERM
(Sunday through next Thursday)
Issued at 317 PM CST Fri Dec 1 2023

No changes to the previous forecast. Quieter weather on tap for later this weekend into late next week as surface high pressure takes a hold over the area. A dry cold front is expected to push through Sunday night into Monday morning followed by a second dry cold front Tuesday night. Surface high pressure will progress eastward, allowing onshore flow to return Thursday. Temperatures through the week will generally be in the 60s with some locations in the 70s. Low temperatures will be in the 40s with a few locations reaching into the 50s.

AVIATION
(00Z TAF Issuance)
Issued at 532 PM CST Fri Dec 1 2023

Passing upper level disturbances have been triggering some scattered tstms south of CXO. This activity should wane in the next couple hours, but would still anticipate a few isolated cells to pop up from time-to-time from IAH southward til 4-6z. Otherwise, a wide mix of aviation conditions expected overnight ranging from VFR for CLL down to LIFR closer to the coast and offshore. Think most of the metro are airports will remain in the lower end of MVFR cigs and perhaps 3-6nm fog. Once the rain tapers off, sea fog will probably re-establish itself right along the beaches and offshore and that's where we'll see the lowest cigs/fog thru a good part of Saturday morning. Substantial improvement is expected during the afternoon hours Saturday as drier air finally filters in and scatters this mess out. 47

MARINE
Issued at 317 PM CST Fri Dec 1 2023

Areas of fog have loomed over the nearshore waters for much of the day, and not expecting improvement going into the nighttime hours.
A Dense Fog Advisory is in effect for parts of these areas until 9 AM Saturday, and it may need to be extended through Saturday evening before a cold front moves through the area and some drier air filters on in. Shower and thunderstorm development is anticipated (better chances today/tonight and lower chances on Saturday) before the front's passage. After all this mess moves on out, light winds and lower seas can be expected on into the middle of next week.
