Dry today with strong high pressure in over the state. This will be the only completely dry day statewide this week. The rains late last week and this weekend kicked off what is going to be a very active pattern as we finish the month.
A weak disturbance will move out of northern IL across northern Indiana into southern lower MI tomorrow. This will bring rains of a few hundredths to about a third of an inch in over the northern half of the state, from I-70 northward. WE expect 60% to 70% coverage in that part of the state with the rains. Some models are trying to bring heavier rain totals in in NW Indiana, but mostly that will be in highly urban areas from Michigan City over through Hammond, Gary and others. So, the agriculture impact of the heavier showers tomorrow will be limited. Southern Indiana should be dry.
Wednesday afternoon into early Thursday morning we have a front sweeping through the entire state. This one brings .05”-.4” rains to 75% of the state. The rains are not overly impressive, but once again, it means we are not drying things down very well.
No new precipitation for the balance of Thursday, but clouds hold firm and we likely do not see much net drying. On Friday, we have another little wave moving across the northern third of the state, bringing rains of a few hundredths to a quarter of an inch in to areas north of US 24. Coverage in the northern third will be around 80%. The rest of the state is dry, but clouds will be close by.
The weekend starts off with some heavy rains. Two waves of strong rain and thunderstorms move through for Saturday and into early Sunday. Rain totals combined can be .5”-2” with coverage at 90% of the state. IT will be a soggy start to the holiday weekend. However, it dries down for the balance of Sunday, and dry weather continues Monday (Memorial Day), as well as Tuesday and Wednesday. This is a change from our outlook last week. The storm is stronger to start the weekend, but moisture is gone for the 30th and 31st, which is where we had been looking to see some more.
In the extended period, we see rains of half to 1.5” moving in for late the 1st into the 2nd with coverage at 80%, and then another front for the 5th and 6th that can have .25” to 1”. The longest dry window we will likely see at this point will be from the afternoon of the 28th (Sunday) through the morning of the 1st. But, that comes after some pretty heavy rains to start the holiday weekend, so we do not expect to be able to capture much of that dry window. The map above shows total rains now through the start of that dry window (through Sunday evening)
