.DISCUSSION (This evening through Saturday)...
Issued at 312 PM EDT Sat May 2 2026

A relatively chilly start to the forecast period with NW flow
aloft. Tonight will again see lows in the 30s and with mostly clear
skies and light winds, there is another chance for frost over most
of central Indiana.

The start of the new week will see multiple chances for rain as some
waves move through and then a cold front Tuesday. Outside of the
rain, wind gusts of 25 to 30 mph are expected to mix down, mainly
during the afternoon hours. Late Monday into the overnight hours,
thunderstorms ahead of the front are possible with a marginal risk
of severe weather as cool temperatures aloft could help increase
lapse rates and instability. Hail and gusty winds will be the main
threat. Best chances for rain come as the front itself gets closer
and approaches from the NW, so Monday night throughout the day
Tuesday. Rain could continue to linger into Wednesday. Around half
an inch, possibly up to an inch in some spots, is expected with this
system.

Along and behind the front will again see below normal temperatures
for mid to late week. Lows for Wednesday and Thursday nights are
forecast to be in the low 40s but the potential to dip into the 30s
can`t yet be ruled out.

An upper wave late week will again lead to slight precipitation
chances but confidence is low at this point.
