Scattered showers move in tomorrow, and continue through the overnight, ending near sunrise on Friday. Rain totals are still expected to be minor at .1”-.4”, with coverage at 90% of the state. However, some models are trying to ramp up those rain totals a bit. We are standing pat this morning. Clouds will give way to sunshine as the day wears on through Friday.
The weekend starts nice on Saturday with plenty of sun and mild temps. However, on Sunday clouds will increase ahead of our next system. That system is coming faster and has less moisture with it this morning. Showers can start to fall already Sunday afternoon, with rain continuing through the night time hours and ending Monday morning. We are dropping rain totals back to .25”-.75” but keeping coverage at near 90%. The main reason we are dropping rain totals at this time is our belief that thunderstorms are no longer a significant concern. With out the thunderstorms, a higher rain range just is not likely. We start to see some clearing Monday afternoon. The map at right shows precipitation totals from now through Monday afternoon.
Tuesday features a mix of clouds and sun, and while we can’t rule out a shower or two, we don’t expect a lot of moisture in this time frame. However, it is becoming clear that we can’t quite get through the day with no moisture. These widely scattered showers will end up with coverage at 30% or less. Partly sunny skies are expected for Wednesday. However, rain then moves into southern Indiana Wednesday night through Thursday morning, bringing up to .3” with 80% coverage. We likely miss out up north. The rest of Thursday we turn out partly sunny and see mostly sunny skies on Friday.
The extended period stars off drier, as we are moving our bigger rain chances back a couple of days. However, there is significant disagreement among many models on how the pattern unfolds with regard to timing and intensity of precipitation going all the way back to the midweek system for next week. Right now, are going to keep the 13th and 14th mostly dry, but then look for several waves of moisture coming through for the 15th through the 18th. Those waves still can bring big rains, with 1-3” possible combined. However, again, the timing of the moisture and fronts is not set in stone by any means, and we could be seeing some changes in this forecast from next Wednesday forward over the next few days. The overall total moisture for the period is similar…but when and how does it come through?
