Area Forecast Discussion
National Weather Service Houston/Galveston TX
1134 PM CST Mon Jan 16 2017

.AVIATION...
Weak, shallow frontal boundary continues to sag into northern 1/3 of
se Tx. This feature will be slow moving and eventually pull up
stationary from maybe roughly Edna-Houston-Cleveland late Tue
afternoon. Moisture will override this boundary, and weak impulses
in the upper flow will initiate periods of shra (maybe some very
iso tstms) along and north of the front overnight thru at least
Wed. Flying conditions will be varied depending on frontal
location and precip, but in general anticipate MVFR/IFR conditions
to mostly prevail. Sea fog will also be a concern in and around
the Galveston Bay area late tonight and Tue morning as well.
Potential for heavier rain exists after 5z Tue thru Wed.  47

.PREV DISCUSSION... /ISSUED 1054 PM CST Mon Jan 16 2017/
Widely scattered showers moving across the northern CWA this
evening...or in the vicinity of a stationary boundary draped
roughly between Brenham and Columbus (southwestern CWA) to between
Conroe and Lufkin (over the northeastern CWA). With no upper
trough/shortwave passage in the short term forecast pushing this
front off the coast...this waffling boundary will remain through
Thursday. An unseasonably high pwat air mass (near 99th
percentile) will be advecting in from the Gulf...within a
marginally unstable regional atmosphere over the next couple of
days...will maintain at least moderate POPs for primarily showers
with isolated thunderstorms. As has been the case over the past 24
to 36 hours...there is enough lower level turning of the winds
that...if a passing shower/storm puts out a strong enough gust
front...downstream lift may rotate. Thus...there continues to be a
mentionable chance for either funnels or weak tornadoes through
mid week. 31
