.SHORT TERM...(Today and Tonight)
Issued at 352 AM EDT Thu Apr 19 2018

An upper level system was over the center of the forecast area
early this morning and was moving southeast. Aircraft soundings
indicated thermal profiles were just cold enough for snow with
surface temperatures just above freezing. Northern Indiana road
pavement temperatures were in the mid to upper 30s. All
indications are that any travel issues should be minor and limited
to early this morning. Skies should clear by early afternoon as
subsidence increases behind the departing wave. Lows tonight
should drop a few to several degrees below freezing. Agricultural
indications are that fruit trees are up to 3 weeks behind the
normal development for this date due to the coldest start to
spring in over 30 years. In this regard, any frost/freeze
headlines will not be issued at this time.

.LONG TERM...(Friday through Wednesday)
Issued at 255 AM EDT Thu Apr 19 2018

A progressive but relatively slow upper level flow will persist
into the middle of next week. During this time, an upper level
system will move east across the CONUS, but will track south of
the Ohio River. North of this system, a weak upper level ridge
will help bring fair skies and warmer temperatures early next
week. Highs should be around 60 to 65 Monday through Tuesday.
Chances for rain will increase by Wednesday as the next system
arrives.
