.SYNOPSIS...

The cold front that tracked through central Indiana yesterday will
move farther southeast into the Tennessee Valley today. However,
there will be some lingering showers and thunderstorms this
morning until the associated upper low moves east of the forecast

into next week with the next chance for any showers and
thunderstorms next Wednesday. Meanwhile, temperatures through the
period will be below normal initially with a warming trend commencing
early next week.

.NEAR TERM /Today/...

Issued at 345 AM EDT Fri Jul 28 2017

The main focus of the near term period will be shower and
thunderstorm chances this morning in association with an upper
low. Currently, there are just some isolated showers over the far
southeast counties. However, will carry mention of slight chance
pops across the eastern two-thirds of the forecast area into early
this afternoon as an upper low rotates through lower Michigan and
into Ohio triggering isolated showers and thunderstorms with it.
In addition, patchy fog will be possible this morning with
lingering moisture and light winds. Temperatures this afternoon
are progged to top off in the upper 70s to mid 80s.

.SHORT TERM /Tonight through Sunday Night/...

Issued at 345 AM EDT Fri Jul 28 2017

High pressure will strengthen both at the surface and aloft across
the Midwest. As a result, dry and sunny conditions can be expected

the period will be below normal with highs generally in the upper
70s to mid 80s and overnight lows dipping into the 50s and 60s.

&&

.LONG TERM /Monday through Thursday/...
Issued at 300 AM EDT Fri Jul 28 2017

Dry weather and seasonal temperatures will be the rule Monday
through early Wednesday as high pressure over the southern
great lakes and Middle Mississippi valley drifts southeast
across Indiana.  Confidence of it remaining dry is pretty good
through early Wednesday...but lower after that.

A weak cold front will move into the southern great lakes late
Wednesday and to central or north central Indiana by late Thursday .
Most models keep central and southern sections dry through
Wednesday...while the latest euro has trended wetter then.  For now
will indicate slight chance POPS far northwest late Wednesday and
chance POPS all areas by Thursday with the arrival of the cold
front.

a lower diurnal range Thursday with more clouds across the area.
