Area Forecast Discussion

559 PM CST Mon Feb 20 2017

.AVIATION...
Axis of -ra should mostly be moving east of the I-45 terminals in
the next couple hours. Main trof axis is still situated to our
east and until that and the sfc front pushes thru Tues, can`t
completely rule out some additional light showers as some guidance
is depicting late tonight and early Tue morning. Won`t advertise
for now however. Do think we`ll see some fog development overnight
with wet ground, light winds and partially clearing skies. Problem
is, confidence as to when/where/visibilities is fairly low attm
and expect some amendments once trends become better established.

.PREV DISCUSSION... /ISSUED 346 PM CST Mon Feb 20 2017/
Areas of rain along with embedded showers and an occasional
thunderstorm or two continue moving northward across much of
Southeast Texas this afternoon as the mid/upper level trof axis
slowly edges eastward across the state. Have continued the
eastward trend of the rain chances overnight and on through early
tomorrow morning, but clouds/fog could linger/develop partly due
to the wet grounds and light winds. Any fog that does develop will
burn off in the morning, and then a cold front will move through
the area during the day with winds shifting to the northwest
behind the boundary. Any lingering clouds across parts of our
northeast and east counties in association with the back side of
today`s storm system should move east of here by late tomorrow
night or early Wednesday morning. It will be on the warm side once
again on Wednesday and Thursday as south winds eventually work
their way back into the area and strengthen under a tightening
pressure gradient. High temperatures both days will be
unseasonably warm with readings in the upper 70s to lower 80s
(around 10 to 15 degrees above normal). The area`s next cold front
on Friday should be on the dry side, and it will be followed by a
couple of cool and dry days over the weekend. 42

MARINE...
Scattered showers through the evening hours should taper off
tonight and will keep the SCEC up through 7 pm for the far waters
for the elevated winds and seas now that will be diminishing. Cold
front moves through tomorrow morning/afternoon and will swing
winds to the west and northwest and may briefly flirt with SCEC
conditions again over the outer coastal waters.

Elevated tide levels returning to near normal Tuesday afternoon. 45
