929 AM EST Friday, November 14, 2014
Though high pressure will build into the region from the west today and
Saturday, lake effect snow showers will continue to affect areas to the
southeast of Lake Erie. These will finally taper off on Saturday.
Some very light snows are possible again late Saturday into Sunday as a warm
front lifts north through the area. .
A more significant wave will move through the southeastern Ohio Valley Sunday
night. This is expected to bring modest rains to the southeastern Ohio Valley
and some snow to the middle Ohio Valley.
Behind this wave, arctic air will push into the basin resulting in temperatures
much colder than normal for the first half of next week.
Temperatures are expected to moderate to closer to normal by the end of next
week. There is the potential for a rain event to affect the Ohio Valley by the
end of next week and into that weekend.

The flood potential is low through this week.
