Scattered showers, mainly along and east of I-45, should dissipate
early this evening. We'll be looking for some patchy fog development
in that same general area later tonight into early Thursday 
morning. Some slightly lower PW air should briefly move into the 
region from the east Thursday & Thursday night shunting the 
majority of rain chances west of the region. 

Friday, we'll see the soupy 1.5-2.0" PWs track back into the region.
Disturbances embedded in the swly flow aloft will be tracking 
newd across Texas, and combined with the higher moisture levels, 
bring chances of rain back into the forecast. Best chances and 
overall coverage currently look to occur during the daytime hours
Saturday. Heading into Halloween evening, fairly warm/muggy 
conditions will prevail for this time of year, but rain chances 
should be tapering down...and continue to do so as the night 
progresses.

Mid-upper ridging will build overhead Sunday in advance of a
deepening/digging lee side trof. This trof will sag southward 
into OK/TX early-mid next week. Timing, positioning, and details 
in regards to when its associated surface front will push through 
are somewhat fuzzy. But with time, we'd anticipate a improving 
model consensus allowing us to narrow down the time period for 
tstms and fropa. Right now there's a range between late Mon night 
and late Tue night. 47

A long easterly fetch situated across the northern Gulf will 
maintain 3 to 4 foot seas for much of the week. Isolated to 
scattered showers and thunderstorms are possible at times as weak 
disturbances pass through. Chances and overall coverage appears 
to be highest on Saturday. The next front is penciled in for 
early next week. 47
