Farewell Indian Summer

We had a good run of above normal September like warmth this week with a string of days 70+! Today is the first day since last Monday we won't record a 70 degree reading at any part of the day. Here is a look back at the temperature observations from the past week. On Friday, the low of 64° set a record for the warmest minimum temperature for the date. This bested the previous record of 62° set back in 1991. Also of note, no other date in the past 153 years of weather recordkeeping between Oct 26 - Mar 22 saw a minimum temperature reading for the day above 63° so this kind of set another new record for that. Temperatures ran nearly 20° above normal last week. A low in the lower 40s and high in the lower 60s is considered "normal" at the end of October.

The passage of a cold front late Friday night into Saturday has and will continue to send temperatures on a downward trend. We spent most of the day on Saturday in the 50s. While we haven't received a whole lot of rain over the past week, scattered showers will continue to remain in the forecast throughout Sunday. Drier Canadian air will start to move into the region pushing the rain out by late Monday morning and ultimately driving temps into the 20s for multiple days this upcoming week starting on Halloween. We haven't had a freeze in over 6 months and we won't close out October without receiving another one.

A wave may push thru the state Tuesday night night bringing the threat for a few light snow showers or flurries but Indianapolis may be too far South and essentially "cut-off" from moisture for this event. Areas closer to the lakes, particularly N / NE, will see the greatest chance. Otherwise, expect a mostly dry week with chilly temperatures through November 1st. By November 2nd, we will get on the return flow of high pressure and temps will moderate to readings that are a little more seasonal for this time of the year.


5 DAY DETAILED FORECAST
SUNDAY: Cloudy Skies. Showers continue through early morning then may ease up with a few dry hours before returning in the afternoon and evening. Winds will be light from the North at 5 - 10 mph. Precip amounts from sunrise (8:10 AM) to sunset (6:46 PM) should be limited to a tenth or quarter of an inch. Temperatures will hover in the lower to middle 50s.

SUNDAY NIGHT: Rain will continue through the late evening and midnight hours. Winds continue to remain light but additional precip amounts may rise anywhere from a quarter of an inch to a half inch. Temperatures will cool into the 40s for much of the night.

MONDAY: Any lingering rain early in the morning should diminish and clouds should gradually scatter. Sunshine may return by the afternoon, if not late in the morning. Winds may turn slightly breezy from the NNW at 10-15 mph with occasional gusts to 20 mph. Temperatures will see very little movement from a morning low in the upper 30s to an afternoon high in the middle 40s. Wind Chill temps will be in the 30s all day.

MONDAY NIGHT: Skies will be mostly clear and calmer winds will be ideal conditions for radiative cooling. Temperature are likely to fall in the middle to upper 20s marking the first freeze of the season. Record Low is 24 set in 1988. Wind chill temps are expected to fall into the upper teens and lower 20s.

TUESDAY: After a frosty and freezing start, sunshine will greet us and we'll quickly warm back up towards the lower 40s by the afternoon. Some clouds may mix in by the afternoon. Winds may gradually increase throughout the day, gusting to 25+ mph at times.

TUESDAY NIGHT: If we miss out on early snow showers or flurries (from sunset to midnight), skies will turn mostly to partly cloudy. Winds will gradually subside. Given broken clouds and winds turning calmer, we'll likely see some frost formation and temperatures again falling into the 20s. The record low is 24 set in 2019. Wind chills are likely to fall into the teens again.

WEDNESDAY: Skies will be clear and sunny but still remaining a little on the chilly side. We'll warm from the middle 20s in the morning to an afternoon high in the middle 40s.

WEDNESDAY NIGHT: Clear skies and cold. Low temps in the upper 20s. Wind Chills in the lower 20s.

THURSDAY: Sunny and turning warmer. High in the upper 40s or lower 50s.

THURSDAY NIGHT: Mostly Clear to Partly Cloudy skies and not as cold but low temps near freezing in the lower to middle 30s.
