...NewARINE... .KEY MESSAGES... - Showers and thunderstorms are forecast to move into the region later this afternoon and evening. A few storms could become severe north of I-10.

- A weak front and gradually weakening, remnant showers/storms will sag toward the coast later tonight.

- A stronger, reinforcing front pushes through Wednesday morning, bringing cooler and drier conditions just in time for Thanksgiving.

Mid-upper trough will continue making its way into the Plains today. In the llvls, 25-35kt H85 winds will draw 1.5-1.8" PW's ahead of an N-S oriented frontal boundary that will be making its way toward western parts of the region later in the day. Look for some shra/tstm development across this boundary this afternoon, as it progresses toward the Brazos Valley after about 2pm or so. Main concern, however, will be any discreet cells than initiate in advance. There will be sufficient instability and shear whereas some of these isolated cells might be capable of becoming severe with all modes of severe weather a possibility. Locations north of about Columbus- Cleveland might be the place to watch between 2-10pm. Elsewhere, there's probably a lower, but non-zero threat of some stronger cells Monday evening/night as storms mainly consolidate along the surface boundary and the threat of the discreet activity lowers. This boundary will become oriented more W-E with time, and llevel jet weakens and becomes SW Monday night. This should lead to diminishing intensity as remnants tracks closer to the coast overnight. So overall, keep an eye on the stand-alone cells this afternoon & evening where severe storms are more probable. Elsewhere along the broken band, I'd look for the main issues to be some 25-50mph gusts and maybe some hail.

Hires data shows this front sagging off the coast early Tuesday morning ending the POPs inland...though some of the globals show it temporarily stalling out during the day with some lingering scattered rain shower chances in the coastal counties during the day (kind of similar to the last front). Don't have strong confidence either way, though I'd probably lean closer to the hires guidance attm.

Stronger push of cool, dry air arrives late Tuesday night and Wednesday morning which should bring some nice seasonable weather through Turkey Day.

Onshore winds resume Friday...drawing deeper Gulf moisture into the region (and warmer temps) this weekend. Global models and blends are all mostly bullish showing a fairly wet weekend...but with a mainly zonal flow and lack of a surface boundary/forcing mechanism in the vicinity, I have a bit of skepticism at this point for total washouts. 47

Look for increasing southeast and building seas overnight and into Monday. May need some caution flags west of Freeport in the morning. The next weather system will move into Southeast Texas later today, with the tail end of some showers and isolated storms toward the coast Monday night. Can not rule out an isolated strong storm in the Galveston Bay area between about 10pm and 5am. Rain chances start to taper off Tuesday depending on when a weak cold front moves off the coast. A secondary, stronger push of cool dry air will move into the waters late Tuesday night and early Wednesday morning. North winds should increase to 20 to 25 knots as this occurs along with building seas offshore. Small Craft Advisories will be required. Onshore winds resume and increase later in the week. 47
