KEY MESSAGES

- 1. Dry weather continues this week with gradually warming temperatures.

DISCUSSION

Key Message 1: Dry weather continues this week with gradually warming temperatures.

No change in the forecast thinking with the extended dry period continuing, and likely persisting through the end of October. Mostly sunny skies continue into this evening with breezy northeasterly winds which have started gusting into the 20 to 25 mph range. Upper ridge will slowly translate east through the week and flatten out by Thursday while surface high pressure remains anchored over the northeast and ridges south across the eastern seaboard. This will result in slightly warmer temperatures each day with fairly high confidence given very small NBM IQRs. Values may reach slightly above normal values by Friday and Saturday. Expect some cooler overnight temperatures, though values look to moderate into the low/mid 50s by Thursday and Friday. The pattern starts to show some signs of breaking down by late week, but rather quietly as opposed to a strong frontal passage.

AVIATION /00Z MONDAY THROUGH FRIDAY/

VFR conditions expected through the next 24 hours.

Little change in the overall pattern as high pressure continues to bring dry and breezy conditions. Passing VFR clouds from onshore flow are starting to clear. No fog remains expected as winds should remain light overnight under a dry air mass. For Monday, clear and dry conditions remain as winds pick back up to 7-10 knots by midday with occasional gusts up to 15 knots.

EXTENDED AVIATION OUTLOOK...Breezy northeast winds expected to persist into next week; although gusts may subside a bit in the 10 to 15 knots range.
