Pretty humid and blustery today. Gotta prime the atmosphere for tomorrow I suppose.

Looks like most of us will see some brief heavy rain with tomorrows thunderstorms(minor localized street flooding may be possible). But more rain is on the menu on Saturday once the main upper low kicks out.With a weak gulf low developing in response,we should see some widespread rain and Saturday may be a washout.But the rain appears to be light at this time.Even though we will need to watch just in case the gulf low develops closer to the coast which could enhance rainfall Saturday.But that doesn't look likely at this point.

Yep and the movement of cutoff low over Baja will more add some additional variables to the equation. Looks to be an unsettled pattern through next week.

From Jeff Lindner Harris County Flood Control Meteorologist

Potential for a stormy Thanksgiving Day

Cool front has progressed into the Gulf waters overnight and refreshing air mass will be short lived as winds quickly turn back SE and S by Tuesday. An upper level trough will be digging into the western US over the next few days with the northern portion of this trough being progressive and moving toward the Great Lakes which in turn will drag a cold front into TX Wednesday into Thursday. The southern portion of this trough looks to cut-off over the Baja region and remain in that area into the weekend (more on that later).

Moisture and warmth will quickly return to TX starting on Tuesday with moisture levels continuing to build into Wednesday and Thursday. Progged soundings show impressive moisture is forecast to be in place by Thursday with PWS of 1.7-1.9 inches over the region which is near maximum values for mid to late November. As the upper level flow transitions to SW aloft a series of upper level disturbances will move across the region starting on Wednesday and into Thursday. Surface cold front will move into the area on Thursday…although timing differences remain in global guidance and when exactly the front moves across the area. All this points to a period of active weather centered around Thanksgiving day with the passage of the frontal boundary in a deep moisture environment. Currently looking at instability somewhat lacking for any severe weather, but some strong storms could be possible. Rainfall amounts of 1-2 inches look likely over much of the area on Thanksgiving Day with possibly some isolated higher totals given the moisture forecast to be in place.

Front appears progressive and should be to the coast and offshore Thanksgiving evening into early Friday with rain ending from NW to SE. However, the southern portion of the trough remains back over Baja and with SW flow aloft over top of the incoming cold air mass from the north, clouds will likely be hard to clear into Friday. A cold air mass will sink into the state with highs likely only near 60 on Friday. Next question is when does the cut-off system near Baja this weekend begin to head ENE and toward TX. Current thinking is this may happen over the weekend into the early part of next week with increasing chances for showers. Such systems are hard to time and usually eject slower than guidance suggests, but they can also send disturbances out ahead of the main portion and this may happen over the weekend, so while the forecast post front on Thursday is a fairly dry one, there is uncertainly and rain chances may be needed in the post frontal air mass over the weekend.

Canadian is giving the Baja low more respect than GFS for widespread rain.

...although GFS has local heavy rain accumulation, mostly off the coast.
