1. Snow will move in after midnight tomorrow night. It may taper a some by late Friday morning to midday.
2. However, new scattered, locally-heavy snow showers/squalls will pass in the afternoon-evening as strong upper trough passes through with cold, cold air aloft. This will result in gusty, convective snow showers/squalls with big, fat flakes & greatly reduced visibility at times.
3. A band of 1-2" of snow will set up for part of area with 1" or less in other places. At this point, the 1-2" band is setting up over the southeastern half of the viewing area, including Greater Lafayette. This could change. Stay tuned.
4. The accumulation will be confined to mainly grassy areas & elevated surfaces with warmer ground temperatures & the temperatures hovering around 31-32 during the snowfall.
Slushy accumulation may occur on less-traveled roads & bridges & overpasses. Main roads look wet.
5. Although most of the snow will all melt away by afternoon (highs 35-39), the showers/squall may deposit localized 1" or less accumulations in the evening with temperatures falling to around 32.
As moisture & any new slush refreezes, a few slick spots may develop Friday night with lows of 20-25 late (as skies clear).
With skies becoming mostly sunny Saturday with highs 34-36 & lows 15-19 Saturday night, we will put the kibosh on much of the fall color before all of it completely matures & the leaves fall off. Saturday will see the wind go very light in the afternoon, so despite the cold weather, the sun & less wind will help it feel a bit better.
Sunday looks a bit warmer with some clouds & more wind (from the southwest) with highs of 39-44.
After some snow showers Tuesday with 30s, it looks to turn quite a bit warmer with even some rain mid-month.
However, much colder air will arrive again after that. Some more minor snowfall could move through the area around November 19-20.
Still looks like potential Nor'Easter late month. Our clipper system & Arctic front may gell with a disturbance moving through the northeastern Gulf of Mexico to blow up coastal storm with snow showers all the way to Birmingham & Atlanta & Columbia.
It will only re-enforce the cold here. Note the large, sprawling Arctic surface high from northern Ontario to the Gulf Coast projected around November 22-23 as Nor'Easter exits.
However, also note big system coming into California. As that happens, it will force some warmth eastward. So, after Thanksgiving, we should see our temperatures warm with some rainfall until they tank in early December (after a mild start to that month).
