.AVIATION /16Z SUNDAY THROUGH THURSDAY/...
Strong to severe storms are possible this afternoon, especially
through 00z. Damaging winds are the primary threat, but large
hail and heavy rain are possible as well. SubVFR conditions are
expected in any storms, with brief IFR/subIFR conditions
possible.
A cold front will push through this evening and shift winds to
the northwest and eventually north. There may be some rain and
low clouds near CHO on Monday through Tuesday, but the greater
risk of sub-VFR ceilings areawide will likely arrive Tuesday
night.
CIGs and VSBYs are likely to cause restrictions on Wednesday prior
to the warm frontal passage due to persistent onshore easterly flow.
CIGs will increase after the frontal passage. Winds turn more
southerly behind the front into Thursday with shower and
thunderstorm chances returning Thursday afternoon into Friday
night.
