.AVIATION...

KGPT, KBIX and KPQL continue to show ceiling between 300 and 700
feet at noon. At the same time, other sites have mixed from 2kft
to 9kft. Will continue to use VCSH at all taf sites through 03z
Saturday as TSRA should remain well northwest of the area. A
return to IFR or lower conditions is likely after 00z Saturday.
Any threat of TSRA at an individual terminal is too low to justify
carrying in the forecast through 18z but 00z evening package will
have to insert some convection after 18z Saturday. 18
