Area Forecast Discussion
National Weather Service Northern Indiana
638 AM EDT Tue Apr 24 2018

Issued at 323 AM EDT Tue Apr 24 2018

Light rain showers and sprinkles will gradually end from west to
east tonight. Cool conditions will prevail the next 3 days with
highs in the 50s to around 60. A brief intrusion of cold air will
allow lows to dip to near freezing Wednesday night. After a small
chance for rain Friday, dry conditions will follow with much
warmer weather ahead early next week.


.SHORT TERM...(Today through Wednesday night)
Issued at 316 AM EDT Tue Apr 24 2018

An upper low was near Nashville early this morning and will move
northeast over the Smokey Mountains tonight. This system combined
with a trio of upstream upper level trofs will provide a chance
for areas of light rain and sprinkles today, then end from west
to east tonight ahead of a cold front. Precipitation amounts will
be light as the bulk of the system passes to the southeast. Highs
today and Wednesday will be cooler than yesterday and should be
mostly in the 50s. A brief intrusion of cold air will allow lows
to dip to near freezing Wednesday night.


.LONG TERM...(Thursday through Monday)
Issued at 316 AM EDT Tue Apr 24 2018

More showers are possible with one more system Friday. Moisture
flux ahead of this system should be very limited allowing a
somewhat narrow band of showers to develop along or just ahead of
the front. Otherwise, much warmer weather is ahead with highs
rising well above normal early next week as an upper level ridge
builds over the region.


.AVIATION...(For the 12Z TAFS through 12Z Wednesday Morning)
Issued at 636 AM EDT Tue Apr 24 2018

Continued expectation of lowering conditions today as higher low
level moisture and associated cold pool advects westward through
northern Indiana with lowest ceilings relegated to northeast
IN/KFWA vicinity. Improvement late in forecast period, especially
at KSBN as shortwave dropping southeast through the Upper Great
Lakes serves to expunge moisture associated with Tennessee Valley


LM...Small Craft Advisory from 2 AM Wednesday to 2 AM EDT Thursday
     for LMZ043-046.
