.AVIATION...
Ceilings continually lowering, winds picking up, and shower
activity increasing ahead and along of a cold front moving into
the area. MVFR ceilings already present at KBPT with KLCH not too
far behind. Ceilings and visibilities will drop into IFR / LIFR
as the front brings about widespread showers and heavy rain. While
instability remains quite low over our area, VCTS will still be
carried at all TAF sites due to tstorm activity noted across
several terminals over eastern TX. The rain will taper off behind
the front from east to west later this evening and into tonight,
however overcast skies will hold on past this forecast period.
Overnight model guidance is suggesting visibilities less than a
mile possible. By morning, visibilities will improve but the fog
will stick around leaving vis below 4-6sm.
