We're capping off the warmest weekend of the year with filtered sun and highs in the 70s.

The shelf life on dry weather is set to expire after dark, as a band of rain and gusty storms arrives around or shortly after midnight in western Indiana. This wave of storms will move across central Indiana between 1-4am, with perhaps another wave arriving toward sunrise Monday.

Though we're not anticipating widespread severe weather, a localized severe gust (>= 58mph) is a possibility. Balmy air remains in place overnight and you'll wake up to temperatures in the 60s.

However, the passage of a cold front late morning/early afternoon opens the gates to unseasonably cold air. Expect temperatures in the upper 30s/lower 40s by 5pm and rain will mix with and change to snow Monday night into pre-dawn Tuesday morning.

Accumulation is not expected, but this will certainly be a jolt to the system after this weekend. Lows Tuesday morning will be in the 20s and highs will struggle to return to the 40s. A widespread frost/freeze appears likely Wednesday morning as clouds clear and the wind diminishes.

But this also marks a turning point, as the air mass quickly modifies and temperatures return to normal Thursday. Have a great evening.
