.AVIATION /06Z SUNDAY THROUGH THURSDAY/...
Conditions are VFR at the terminals early this morning, but
ceilings are expected to drop to MVFR as showers and
potentially a few thunderstorms associated with a cold front
approaching from the west move through. For now the thunderstorm
potential has been highlighted in the TAFs with PROB30 groups,
but if confidence in their occurrence increases, TEMPO groups
may be introduced. Winds are currently gusty out of the south,
but will shift to the west and then northwest as the front moves
through. Improvement back to VFR conditions is expected this
afternoon, as northwesterly winds gust to around 20-25 knots.
VFR condtions will then persist through at least the middle of
the week.
Breezy to windy conditions expected today through Tue with gusts to
30 kt, mainly during the daylight hours. Winds begin to diminish Wed
afternoon.
