Key Messages
1) Quiet, dry weather continues into next week.
Discussion
KEY MESSAGE 1... Broad surface high pressure will maintain dry and mostly sunny conditions through early next week. Dry and clear conditions with light wind will also lead to 25-30 degree diurnal temperature ranges with lows in the 30s and lower 40s and highs in the 60s. Patchy frost potential remains possible this morning and again Saturday and Sunday mornings, though the growing season is rapidly coming to an end in those areas that have yet to experience hard freeze.
Aviation
High confidence VFR conditions continue through the weekend, save for isolated/patchy morning river valley fog. Clear skies continue with light northerly wind today.
Outlook... Outside of any morning river valley fog, VFR is highly likely through Monday under high pressure.
