and low to mid 60s. Clouds will be on the decrease tonight, giving
way to partly cloudy skies Friday. Highs Friday will climb into
the 70's. Rain chances and perhaps even a few thunderstorms will 
move into the northwest late Friday night, and into the remainder
of the forecast area Saturday and Sunday. Highs will be in the 
upper 60's and 70's.


.SHORT TERM...(Today and Tonight)

A weak low pressure area was over east Ohio and was moving east 
early this morning. Areas of light drizzle and patchy fog were still 
quite extensive west of this system over Indiana and northwest Ohio. 
Have extended the mention of patchy fog and light drizzle given the 
latest obs and trends. The drizzle should end this moving as the low 
moves east and as drier air spreads southwest across the area. Highs 
today will be a little below normal as cool air continues to spread 
over the area. Most of the clouds should linger tonight with lows 
holding in the 50s.


.LONG TERM...(Friday through Wednesday)
Issued at 416 AM EDT Thu Oct 12 2017

Temperatures will rise well above normal again ahead of the next 
system that will arrive this weekend. The ongoing forecast appears
on track as the latest models continue to favor the low pressure 
area moving across Wisconsin into Upper Michigan by Sunday. Very 
favorable upper level support will spread over the area Sunday. 
Storms with gusty winds are possible with some storms possibly 
becoming marginally severe. Otherwise, very limited cold air
advection will be behind this system allowing temperatures to 
quickly recover and rise well above normal again early next week.

development late tonight into Friday morning at both sites, but 
confidence in this is slightly lower. Kept conditions MVFR for
