Most of the state will be dry through tomorrow. Moisture may slip into northern Indiana later tonight and tomorrow, but mostly we expect just clouds. IF scattered showers to develop in the northern tier counties, rain totals for Thursday will be mostly a few hundredths to a tenth or two. On Friday, we do see slightly better-organized moisture sagging southward, bringing a .05”-.3” spots of rain to about 60% of the state. This will skew toward the northern and eastern sections of the state.
The weekend will be mostly dry over at least 80% of the state. The focal point for moisture coming across the great lakes region for the weekend will be more in OH. However, that track does put north central and northeast Indiana at risk of some associated showers and thunderstorms moving through for Saturday and even some on Sunday There could be a nice thunderstorms outbreak overnight Saturday night into Sunday as well, coming from Lower Michigan down into OH that will need to be watched for offshoot thunderstorms into northeast Indiana. All told, we can see showers up to half an inch over the north and northeastern most 20% of the state, with scattered coverage. The rest of the state stays dry and warm through the weekend.
Next week is dry for Monday, Tuesday, and Wednesday. We are keeping a front in for next Wednesday night through Thursday, but also keeping rain totals at a quarter inch to 1.25”. However, we are expanding coverage to about 60-70% of the state, rather than keeping action south of I-70. This system has been the subject of much disagreement between forecasters and models. At this time, we do not think it is going to be the big-time heavy rain maker for the heart of the Corn Belt that is being advertised by others and believed by the markets. Behind that front, we go dry again for the rest of the week and weekend.
In the extended period, we have a weak front for the 31st of July that can bring up to half an inch of rain, but then we go dry again for the start of August with a large upper level high and a strengthening ridge over the eastern Corn Belt. Temps will be above normal for the remainder of the month and to start next month.
