Area Forecast Discussion
National Weather Service Northern Indiana
317 PM EDT Mon Oct 16 2017

Issued at 307 PM EDT Mon Oct 16 2017

High pressure will dominate the weather this week with a warming
trend and dry conditions. High temperatures will rise into the
60s Tuesday and continue into the 70s by mid to late week. Low
temperatures Tuesday morning will be in the upper 30s to lower
40s. Patchy frost is possible in sheltered areas where winds
become calm. The next chance for measurable rainfall will not
arrive until Saturday night or Sunday.


.SHORT TERM...(This Evening through Tuesday)
Issued at 307 PM EDT Mon Oct 16 2017

A few sprinkles showing up this afternoon with weak flow still off
lake along with weak cyclonic flow in northeast. These should
dissipate quickly late this afternoon and evening followed by
clear skies and light winds. With high pressure to our south a
weak gradient does look to keep sfc winds in the 3-5 knot range
overnight with a slight increase toward daybreak. This will
hopefully preclude frost formation but expect any outlying and
sheltered areas could see some patchy frost.

Dry and mild Tuesday with high pressure dominating.


.LONG TERM...(Tuesday Night through Monday)
Issued at 307 PM EDT Mon Oct 16 2017

Gradient with high pressure to our south will keep daytime winds
in the 10 to 15 knot range this week but skies to be mostly clear
and no impactful weather. Temps will slowly climb into the 70s,
well above normal. Next chance for rainfall looks to be late
Saturday night and Sunday. Blends yield likely pops and basically
for purpose of consistency among neighbors have stayed with these
values. However...approaching front to likely encounter staunch
ridge and models probably overdone or off on timing so expect
some temporal adjustments later this week to grids and pcpn
