Another cold day today over the state, but we should see some better sunshine potential through the day, as winds shift just a bit, and we see less of an influence from the Great Lakes. Do not get used to any sun you see, though. Clouds roll back in tomorrow and we finish the week with a significant rain maker.
Tomorrow, with the clouds, we can’t rule out some minor precipitation. We are likely going to see a few scattered snow showers in the north in the morning, and then a chance of sprinkles or flurries off and on later in the day farther south. Then, overnight tomorrow night, there can be a few spits and sprinkles in southern Indiana. Warm air will begin to work over the state, initiating this moisture, but we do not expect much at all…only a few hundredths to a tenth with coverage at 50% of the state. Clouds hold through the day Friday, but temps climb, and we should stave off any additional precipitation on Friday.
Big rains arrive early Saturday morning and sweep across the state through the rest of the day, all the way through midnight Saturday night. Strong gusty winds will accompany the rain, and we will not rule out a thunderstorm. Rain totals will be from half to 1.5” over 100% of the state. The storm circulation is so strong, though, that we likely see a dry slot rotate in for Sunday. Temperatures will stay well above normal for Sunday, but we can escape with little to no precipitation as the weekend ends. Still, half to 1.5” rains on Saturday will be more than we need. The map above shows cumulative rains for the event through Sunday night.
Cold air finally blasts into the state overnight Sunday night through Monday, as we get the backside circulation coming in from the north and west. This promoted some light snow through Monday, mostly north of I-70, and we can see a fresh coating to no more than an inch. Winds coming down the fetch of Lake Michigan mean we can see some lake effect snow in far northern Indiana and up in to Michigan. Southern Indiana likely just turns colder with a mix of clouds and sun. Cold air remains over the state from Tuesday through Thursday, but we are scaling back precipitation threats for Tuesday and Wednesday and leaning toward a drier forecast for those days.
No change in our extended forecast this morning. There is a small chance of light snow next Friday, but coverage and amounts are underwhelming. Better precipitation rolls in for Sunday the 9th but still looks to stay mostly north of I-70 Michigan and Ohio are in the line of fire for that event. Some leftover light snow falls to start the week after next on Monday, but then we turn warmer for the next three days, Tuesday through Thursday, with above normal temps. This will lead to another significant storm complex around the 15th or 16th.
