.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
Upper level low over southwestern Ontario will keep cool northwest
flow flowing off of the Great Lakes today.
This afternoon could see some gusty winds with 15-20 knots at
times, most likely in the early to mid-afternoon, along with an
increase in VFR stratocumulus.
Isolated showers may linger in the northern tier over the next
few hours, but coverage and intensity is expected to be low.
Skies will gradually clear out this afternoon into the evening
as the upper low pivots out to the northeast. This gives way to
clearer skies tonight and calm winds into Wednesday morning.
Model guidance hints at patchy morning fog building in
tomorrow morning with signal strongest in the northern
airfields. IFR to LIFR restrictions are possible with fog that
develops. Once fog burns off in the morning, VFR conditions are
expected through the end of the TAF period.
Outlook...
Wed...Patchy morning fog, otherwise mainly VFR conditions.
Thu...Restrictions possible in scattered afternoon showers and
storms.
Fri...Still a slight chance of a shower, VFR otherwise.
Sat through Sun...Clearing conditions, VFR favored.
