Area Forecast Discussion
National Weather Service Northern Indiana
122 PM EDT Thu Oct 12 2017

Issued at 115 PM EDT Thu Oct 12 2017

Cloudy skies are expected to continue through tonight into early
Friday. Skies will become partly sunny on Friday and it will be
warmer with highs in the 70s. 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)
Issued at 416 AM EDT Thu Oct 12 2017

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.


.AVIATION...(For the 18Z TAFS through 18Z Friday Afternoon)
Issued at 114 PM EDT Thu Oct 12 2017

Cigs only slowly rising today as expected and KSBN has finally
reached MVFR while KFWA still holding in IFR conditions. Expect
slowly rising cigs rest of the day. Uncertainty tonight on whether
CIGS will maintain MVFR category or drop back down to IFR with
nocturnal cooling. Remained optimistic with MVFR cigs and some BR
development but confidence low given moist low levels. Similar
uncertainty for Friday on how fast clouds will break up. Kept a
BKN MVFR deck in both terminals through end of period.
