While no one day will be a rain-out through your weekend, we are expecting a soggy weekend here in Central Indiana. Overall rain totals could approach an inch and a half to two inches of rain in some isolated spots with most likely seeing about an inch of rain. Temperatures will remain unseasonably warm through Saturday ahead of a potent front that will arrive Sunday morning. Temperatures will drop to the 40s for a couple of mornings behind the front.
Friday highs should hit the 80s again after we hit 82 degrees for a high on Thursday. Technically we will be in the ‘warm sector’ today through Saturday meaning isolated storms with some light rain will be possible. A vigorous upper low is sliding in from the Rockies and will take shape and become better defined today. This is where our front is coming to come from and we could still be drying out and clearing out on Monday depending on the exact track of the upper low. Models sometimes have a difficult time accurately tracking lows as they move over the Rockies, but I expect possible tracks of the storm from model data to tighten up today as the storm takes shape. It also looks like we will see some sunshine today as we head into the afternoon after some clouds and light rain pass through the state this morning.
Saturday is looking wet with scattered to widespread showers with some storms sliding through the state all day long. It looks like the rain will be picking up throughout the day. Front slides through on Sunday morning with strong storms being possible along the leading edge. There will be a risk of severe weather as the front slides through.
Behind the front we get a little taste of fall with lows falling to the 40s and possibly thirties in a city or two. Highs on Monday and Tuesday will struggle to hit 70 degrees. Next work week will be dry though.
