.AVIATION /08Z MONDAY THROUGH FRIDAY/...
VFR conditions are expected through Wednesday as high pressure
dominates the weather pattern. A weak cold front will approach
Wednesday, but likely won't result in any flight restrictions.
Gusty winds are expected this afternoon though as a weak cold
front pushes through from the north. Winds could gust up to 25
knots at times out of the NW. High pressure builds over the
area, then shifts offshore on Tuesday, shifting winds once again
out of the south to southwest at around 20 to 25 kts.
By Wednesday night, the aforementioned frontal boundary will
start to lift north through the region. This could bring sub-VFR
CIGs.
A cold front will approach Thursday with a chance for brief sub-VFR
conditions in showers and low clouds. Southerly winds may gust above
20 kt as well. The next low pressure system may arrive on Friday,
but confidence in timing and impacts is low.
