.AVIATION /06Z TUESDAY THROUGH SATURDAY/...
VFR conditions are expected at the terminals through the day
Wednesday, although rain may be possible at times during the
daylight hours on Wednesday. Ceilings may lower for a brief time
Wednesday evening before conditions return to VFR late Wednesday
night. VFR conditions will then continue through the day
Thursday.
Winds will generally be light out of the south to southwest both
today and Wednesday. LLWS may be possible for a few hours this
evening. Winds will turn out of the northwest Wednesday night as
a cold front moves through the area. Northwest winds will likely
gust to around 20-30 knots Wednesday night through the day
Thursday.
Mainly VFR conditions are expected Friday into Saturday, though some
shower activity could wander east of the mountains Saturday. At the
moment, winds look to be westerly Friday morning, then southerly
Friday afternoon through Saturday evening before becoming west to
northwesterly again late Saturday night. This will be contingent on
the passage of a couple fast-moving waves which come with inherent
lower predictability. Some gusts of 15-20 knots are quite possible
during the daylight hours each day, but overall winds less than 10
knots are most likely during this time.
