.AVIATION...
Foggy conditions have slowly improved at the terminals late this
morning, with metar reports of VFR-IFR VIS, though IFR-LIFR CIGS
continued to plague the terminals. VIS is anticipated to continue
to improve throughout the afternoon though patchy fog may linger,
whereas the CIGS will remain low. Shortly after sunset, VIS will
deteriorate back to IFR to possibly LIFR criteria whilst chances
for -SHRA commences to near klfk /perhaps as early as late this
aftn/. -SHRA will spread northward to the remaining terminals this
evening into tonight, with increasing instability leading to the
potential for VCTS. Have tried to insert the correct time-frame at
each terminal for the onset of precipitation. Otherwise, light
east-southeast winds will veer a bit to the south-southeast 
throughout the TAF cycle.
