National Weather Service Houston/Galveston TX
947 PM CST Sat Feb 18 2017

.UPDATE...
A few minor tweaks were made to the wx grids to capture forecast
fog trends. Fog is already settling in over Galveston Bay and the
nearshore waters this evening. This fog will gradually move
inland throughout the night before retreating back offshore
tomorrow. Otherwise, the previous forecast appears to be on track
with the next system pushing through SE Texas Sunday night
through Monday. 11

AVIATION...
Very few changes were made to the ongoing TAFs for the 00z cycle.
Looking for some sea fog to develop near the coast this
evening...which may impact LBX, HOU & SGR overnight. Not as
confident at IAH, but suspect we`ll see some IFR cigs fill in -
like the rest of SE Tx. Gradual improvement expected areawide
after 15Z with some VFR conditions for most after 18z. Will
introduce rain chances in the next set of TAFs for CLL and IAH as
chances increase late tomorrow evening and overnight.  47
