Chilly, Windy Weather

Unseasonably cool temperatures will continue this week as a piece of the polar vortex breaks off over the eastern United States and merges with former Hurricane Sandy. While this will be a historic storm for the East Coast, the first half of this week will be mainly cold and windy across the Ohio Valley. Sustained northwest winds of 20-30 mph with gusts over 40 mph will be possible Tuesday and Wednesday, with the strongest winds expected Tuesday afternoon. Lows will be in the 30s with highs in the upper 40s and lower 50s.

Any light precipitation on the back side of former Sandy would likely impact southeast Indiana and east central Kentucky tonight through Halloween night primarily in the form of light rain.  However, temperatures tonight and Tuesday night may be cold enough for a few snowflakes to mix in with the rain east of Interstate 75.   There will be no snow accumulation, other than perhaps a light dusting in grassy areas east of a Cynthiana-Winchester line.

Below is the forecast weather map for Tuesday evening, showing Sandy centered over Pennsylvania and cold north/northwest breezes over the Ohio Valley.
