Area Forecast Discussion
National Weather Service Northern Indiana
1230 PM EDT Mon Oct 3 2022

.SYNOPSIS...
Issued at 312 AM EDT Mon Oct 3 2022

A large high pressure area will settle over the region and will help
keep skies clear to mostly clear with light winds into Wednesday.
Large diurnal temperature spreads are ahead with lows 35 to 45 and
highs 65 to 75. Patchy frost is possible tonight. The arrival of
colder air will bring a good chance for a widespread frost Friday
night.

.SHORT TERM...(Today through Wednesday)
Issued at 312 AM EDT Mon Oct 3 2022

A large surface high was over northern Lower Michigan early this
morning. This system will drift south and settle over northern
Indiana and is likely to bring patchy frost tonight as temperatures
dip below 38 degrees in some locations. Light winds and clear to
mostly clear skies will persist into Wednesday. Large diurnal
spreads are a good bet with highs exceeding lows by 30 degrees or
more in some places today and Tuesday. Lows will be from 35 to 45
with highs 65 to 75.

&&

.LONG TERM...(Wednesday Night through Sunday)
Issued at 312 AM EDT Mon Oct 3 2022

High pressure will be retreating to the southeast Wednesday as a
front approaches from the west. The strong cold front is expected to
be accompanied by scattered showers Thursday into Thursday evening.
Little instability, limited moisture and some upper level support
should should be just enough for scattered showers. Any precipitation
should be light. Much colder air will settle over the area late
in the week. At this time, the coldest nights appear to be Friday
night and Saturday night according to the latest EC, GFS and
Canadian GEM. Believe widespread frost is likely with the chance
for a hard freeze both Friday night and Saturday night. Lake
clouds may limit frost development downstream of Lake Michigan.

&&

.AVIATION...(For the 18Z TAFS through 18Z Tuesday Afternoon)
Issued at 1230 PM EDT Mon Oct 3 2022

High pressure will remain in control through the TAF cycle with
VFR conditions, light winds, and little in the way of cloud cover.
