Highs today reached 56-64. I forecasted maxes of 60-67 lastnight, so we fell 3-4 degrees short. However, 78-84 highs for tomorrow still look good after the scattered showers/storms exit tonight & some fog develops.
Lows clouds & fog will then erode away tomorrow morning, leading to a mostly sunny to sunny, windy (south-southwest gusts to 35 mph at times) afternoon.
Lows Thursday night-Friday morning look near/record warm at 61-66. The record warm low for Greater Lafayette (records back to 1879) is 63 in 2001.
Friday cold front still looks anafrontal. Much of the shower & storm action will occur behind the front.
So, we get an initial narrow line of gusty showers & t'showers with some isolated +45 mph gusts, then showers & storms with risk of isolated hailer or two with temperatures crashing to the 50-60 range after reaching 67-78 over the area in the 11 am-2 pm time frame.
It will be warmest in the southeast counties where it will take longer for the front to pass.
Rainfall of 0.35-0.75" is possible.
Saturday looks dry, Sunday should see scattered showers & some storms develop as the front comes back northward as a warm front.
How far north the front gets will determine how warm it gets Monday & how far north MARGINAL & SLIGHT RISK parameters get Monday. There is a trend to keep us a bit north of the warm front & in the 50s.
I think it could even be a situation where it is 60s Lafayette & southward & 50s north of that. Just count on wet weather increasing Sunday & lasting periodically through Monday with risk of a few to some storms.
Total rainfall of 0.75-1.50" is possible.
Tuesday & Wednesday look cooler with it turning drier. Highs will run 47-56 Tuesday & 48-57 Wednesday north to south over the area. Overnight lows of 30-37 are likely.
