.AVIATION...

The main concern for the 12z TAF package will be the chances of
TSRA affecting terminals today, and the possibility for either
reduced flight categories due to fog and/or low clouds at sites
later tonight. The favored areas for convection today will be in
the higher terrain of the mountains initially, but expect some
drift into lower elevations this afternoon and evening. Whether
storms will affect any given terminal is not concrete, so left it
with just a mention of VCTS at all sites to cover it for now. For
the low clouds/fog chances for tonight, I went with a persistence
forecast there and will just advertise SCT025 towards the end of
the period at KCHA, and will go with 5SM at KTRI as MOS guidance
is strongly hinting at lower vsby there.
