Lows this morning ran 43-50.
It does not look like much rain Wednesday night. Trace to 0.25" will occur with a few scattered fast-moving showers & isolated t'showers.
Dry slot in Thursday morning means sun & 60s, then low clouds roll in for the midday to afternoon with northwest winds & temperatures falling into the 50s.
Friday looks rather gray & cool with 54-58 & a few sprinkles to isolated light showers possible.
It appears the clouds may hang on well into Friday night, complicating the temperature forecast. If the overcast hangs on then lows will only drop to the 40-45 range. If we see partial clearing, then 35-40. If we are completely clear with a light wind then frost & 30-34.
Right now, trend is for broken clouds, so went with lows 37-42.
Saturday looks partly cloudy as any stratocumulus depart & high & mid clouds increase a bit. Highs will run 57-62 with an east wind as front moves back north as a warm front.
With clouds, lows on Saturday night should run 40-45.
That warm front will arrive Sunday & then gradually push northward through Monday with east to southeast winds.
Some scattered showers & isolated storms are possible Sunday PM-Sunday night to early Monday AM. Temperatures should run in the 55-59 range Sunday.
Behind the warm front we should warm to 75-80 Tuesday with a strong south wind 15-25 mph with partly cloudy skies, followed by near/record warm night with lows of 62-66.
As for Wednesday, it looks partly cloudy & windy with near/record warmth day & night with highs 78-82 & lows 64-67.
Thoughts are that the main surface cold front & upper trough will pass through Thursday morning with line of storms, then some rain behind it.
Parameters suggest MARGINAL to SLIGHT RISK.
We should be back to highs of 55-60 October 29.
At this point, there is no sign of any freezing weather until around November 8. If we do not get to 36 by November 8, it would be the latest occurence of first 36 on record. The all-time record is November 7, 1940 for the first 36 or lower temperature.
We will monitor.
The latest first freeze on record occurred November 13, 1946. It does appear we will get the first freeze before then at the official daily Greater Lafayette observation site, the Purdue University Airport.

It is possible that we do not drop below 20 in November.....it is POSSIBLE.
HOWEVER, once winter roars in during early December, it will really roar in, it still appears with below to well-below normal temperatures & snow risk. There are signs we will not budge out of that pattern totally until after Christmas, then we have a 3-week long wet, mild stretch with a lack of snowfall.
