Area Forecast Discussion
National Weather Service Northern Indiana
700 AM EDT Sun Apr 23 2017

.SYNOPSIS...
Issued at 651 AM EDT Sun Apr 23 2017

Weak high pressure will remain over the area through Tuesday
accompanied by clear to partly cloudy skies and light winds.
Highs today will be in the upper 60s to around 70. Highs Tuesday
will be generally in the mid to upper 70s.

&&

.SHORT TERM...(This Evening through Sunday)
Issued at 303 PM EDT Sat Apr 22 2017

High clouds have impacted much of the area, but did little to
stop highs from reaching middle to upper 50s in most spots.
Thicker clouds in SE areas have kept much cooler (upper 40s to
around 50).

Ridge axis will be slowly dropping south, but low pressure passing
well south of the region was allowing some impedance of the
ridging, resulting in concerns as to frost potential tonight.
Skies should generally clear and winds drop once again, but exact
duration of more favorable conditions worrisome. Do think some
patchy frost will materialze, especially in areas with good
drainage that can decouple early enough. Opted for a SPS to handle
frost threat for the entire area.

Temps will rebound nicely Sunday under mostly sunny skies, with
highs well into the 60s.

&&

.LONG TERM...(Sunday Night through Saturday)
Issued at 303 PM EDT Sat Apr 22 2017

Dry forecast remains in place through at least Tuesday night and
probably most of Weds before the next trough moves towards the
western lakes. Low pressure will track along a cold front mainly
Weds ngt bringing a chance for showers and storms. Still some
concerns on timing but both GFS and EC have at least for the
moment come into better agreement. Prior to the arrival of the
system, highs will continue to moderate with the warmest day being
Tuesday.

Temperatures will head back to more seasonable levels as warmest
air is pushed well south. Low pressure will develop in the
southern Plains and possibly impact the area over the upcoming
weekend.

&&

.AVIATION...(For the 12Z TAFS through 12Z Monday Morning)
Issued at 651 AM EDT Sun Apr 23 2017

Weak high pressure will keep VFR conditions through the TAF
period. Winds should remain under 10 knots.
