SHORT TERM [Tonight through Friday Night].

Overall, not much change to the synoptic pattern over the past 24 hours with weak surface high pressure continuing to reside over the area and wind speeds remaining light. With winds expected to become calm once again tonight and model soundings indicating favorable low- level saturation and a relatively strong nocturnal inversion, another period of fog looks to be in store. SREF probabilistic guidance shows the best potential for dense fog roughly along and south of the I-10 corridor, and another Dense Fog Advisory may be needed. As we saw this morning, conditions may once again be difficult for travel come morning commute time and as a result those planning to be on the roads early tomorrow morning should consider leaving themselves some extra time.

A pattern shift will develop tomorrow as the dominant surface high pushes eastward into the Tennessee Valley, allowing for a redevelopment of a more persistent onshore flow. Precipitation chances will start to creep upward by the afternoon along the coast as a more robust plume of moisture pushes towards shore. The greatest chances for showers and storms will remain centered around Matagorda Bay before expanding on coverage on Saturday.

Temperatures continue to run above seasonal normals, with daytime highs in the mid to upper 80s and overnight lows mostly in the upper 60s to lower 70s.

LONG TERM. [Saturday through Thursday] .

Tightening pressure gradient over the region (via falling surface pressures to our west and the surface high to our east) will help to strengthen onshore winds and increase moisture levels over the CWA this weekend. Warm/humid conditions will persist with perhaps isolated to widely scattered activity developing over the coastal waters early in the morning and spreading inland during the after- noon each day. Highs this weekend will be in the mid to upper 80s with lows in the 70s.

We're still looking for increased POPs next week as the generally zonal flow aloft begins to transition in response to the next mid level trof deepening in the lee of the Rockies. Rain chances will likely be further enhanced as this system taps into Pacific moist- ure (from a possible tropical cyclone) ahead of the a strong cold front by Tues on into Wed. The latest long-range solutions appear to be coming together in terms of timing with these next systems, but we're still talking days 5-7 at this time. For now, will keep with the isolated to scattered POPs (20-40%) already in the grids for this time frame. 41

MARINE.

With very similar conditions to last night expected for tonight, we could see the return of patchy dense fog along/near the immed- iate coast/bays. These lower visibilities should burn off by mid morning tomorrow. Otherwise, no major changes from the generally quiet conditions over our marine waters. Light E/SE winds should continue through Sat. A tightening pressure gradient in response to the next storm system moving into and then deepening over the Southern Plains will likely produce slowly strengthening S to SE winds by late Sat . along with increased chances for showers and thunderstorms. Conditions could approach SCEC criteria Sat night and persist into Sun. This moderate to strong onshore flow is ex- pected to remain in place through first part of next week. 41
