It has been an off & on battle to rid the viewing area of these low, gray stratus clouds since last night. Out southwestern counties have had the most sunshine today, but high/mid clouds are overspreading the area from southwest to northeast.
In low solar winters (lack of sunspots) there tends to be a higher incidence of stratus cloudiness getting trapped & lasting for days. 2009-10 & 2014-15 are good examples of very cloudy winters......bot El Nino Modokis & both in low, low solar winters like this one.
This results in days that look sunny from a model standpoint ending up mostly cloudy or even cloudy.
Looks like the culprit today is some extra moisture from Lake Michigan that has gotton trapped & a weak surface high or "Dirty High" that has trapped the stratus deck.
Also, if you look closely at the visible satellite image, you can see snow cover in the area, especially just southwest of Crawfordsville where the snow shows up well in the rugged, wood, stream-laced terrain around Shades & Turkey Run.
A few snow, sleet & freezing rain showers are possible after 6 a.m. tomorrow morning before change to just a few scattered cold rain showers by midday-early afternoon.
Highs will run 34-40.
Any snow/ice accumulation should only amount to a trace. However, any of the precipitation that dampens roadways could lead a couple slick spots.
Friday looks tranquil, but Saturday will feature widespread, wind-driven rainfall in the morning. East winds may gust to 43 mph.
Then, rain should exit by noon & winds go to the southwest, then west with gusts up to 40 mph. Some sun may even appear at times with a scattered of showers & t'showers passing through.
With storm passing even farther north (southeastern Wisconsin), it looks warmer. Highs should range from 54 in the north to 61 in the south & 57 at Lafayette. This, after 40s & all of the rain in the morning. Sunday looks showery with highs in the 40s.
So, for the Christmas parade in downtown Lafayette, could on windy, mild conditions with some scattered showers & t'showers around. It will be on of the more spring-like parades we have seen!
0.75-1.25" of rainfall is possible Saturday-Sunday, which will lead to renewed rises in area rivers & streams. Lowland flooding will return to the Wabash.
Severe weather will occur from Oklahoma to Kentucky to the Gulf Coast.
Much colder weather will follow with snow possible early to mid-next week. The below to well-below temperatures look to be dominant right through mid-December.
