WHAT HAS CHANGED

Temperatures have trended a little bit cooler for tonight, but otherwise no significant changes were needed with this update.

KEY MESSAGES

1) Dry weather and fall temperatures are expected through Tuesday with rain chances returning by the middle of next week.

DISCUSSION

KEY MESSAGE 1... High pressure will maintain influence over the region through early next week, resulting in prolonged dry weather and slightly below normal temperatures through Tuesday. Tonight will be the chilliest night of the week with widespread lows in the low to mid 40s expected at inland locations. A few spots across interior NW PA, particularly in valleys, will likely dip into the upper 30s and there is a chance that a few spots across interior NE OH drop below 40 degrees early Friday morning. As far as frost potential goes, 925mb flow may be a bit too high to allow for frost development. However, if flow lightens enough, there will definitely be sufficient clearing for very isolated instances of frost, particularly across far eastern Erie/Crawford counties in PA and perhaps typical cold spots across interior NE OH.

High temperatures will generally be in the 60s through Monday or Tuesday, although temps across the western half of the area will likely warm into the lower 70s Saturday through Monday. Widespread low 70s are expected by the middle of next week.

The next chance of rain will arrive Wednesday through Thursday as a low pressure system moves across the Great Lakes region.

AVIATION /00Z Friday THROUGH Tuesday/

High pressure building south into the region will provide VFR conditions through the TAF period. Winds will generally be northeast through the region, increasing to 10 to 12 kts during the daytime hours. High clouds will build into the region from the west during the day on Friday but should fizzle out by evening.

Outlook...Mainly VFR favored through Tuesday, though periods of overnight patchy fog are possible.

MARINE

A period of northeast winds to 15 to 20 knots is expected in the central and western basins late this afternoon into this evening, which will produce a moderate swim risk and waves of 2 to 4 feet tonight. Small Craft Advisory conditions may very briefly occur from roughly the Islands to Geneva-on-the-Lake this evening. By late tonight, winds will become southeasterly and diminish to 10 knots or less, although winds will once again become northeast and increase to 10 to 15 knots during the day Friday. Similar flow will persist through the weekend with wind direction periodically becoming more northerly. Waves will generally be 1 to 3 feet Friday through the weekend.
