Area Forecast Discussion
National Weather Service Houston/Galveston TX
1148 PM CST Tue Jan 17 2017

.AVIATION...
Will be keeping with a fairly messy forecast as the unsettled wx
pattern remains in place. Moisture moving in from the Gulf along
with disturbances tracking across from the SW being the main is-
sues. Sea fog starting to develop at this time and GLS should be
dealing with this through the early morning...and possibly again
early Wednesday morning. Have timed TAFS with a round of TSRA at
to around sunrise...then another during the afternoon/early eve-
ning hours. We are also seeing a smattering of fog/VIS issues at
sites not yet affected by the approaching activity. 41

.PREV DISCUSSION... /ISSUED 916 PM CST Tue Jan 17 2017/

Just minor adjustments to the forecast for the update. Shallow
frontal boundary has stalled inland and not expecting it to move
much overnight...and just slowly back north on Wed. Nearly steady
temps expected for most.

Combination of Gulf moisture overrunning this boundary along w/
the addition of impulses and Pacific moisture associated with the
messy sw flow aloft will aid in increasing precip coverage moving
into the region overnight. Rain totals will eventually add up w/
nearly steady light/moderate rains. Will however need to keep eye
on heavier cells/bands that manage to develop as training precip
is expected.

Between roughly I-10 and the coast, in the vicinity where the
frontal boundary is parked, we`ll also need to keep an eye for
some isolated strong/severe cells later tonight into Wed.

Beaches and offshore areas may be left out of much excitement in
the short term, but will have to suffice with some thickening sea
fog again. May eventually need to throw out some dense fog advsys. 47
