High pressure over the state this morning moves off to the east and will allow for light south winds to warm us slightly over what we saw yesterday. We should be dry statewide with a mix of clouds and sun. Clouds will start to increase overnight tonight.
Tomorrow, minor low pressure tracks across the eastern corn belt. This will bring plenty of clouds and a few scattered showers. We expect a few hundredths to no more than .25” of precipitation but are boosting coverage to 75%. This will be a relatively quick moving system. The best rains in the upper part of the range will be in northern Indiana.
We are unchanged this morning in our outlook for the second half of the week, expecting dry weather with partly to mostly sunny skies Thursday through Saturday with warmer air pushing up from the south. We expect above normal temps to finish the week.
Clouds develop on Sunday, but we are less concerned with precipitation at this point. While we won’t rule out an isolated shower through the day, we think most of Sunday will be precipitation free. This is not a huge change, and we still see significant moisture coming for the first part of next week. That will be where the bigger rains move in. For Monday and Tuesday, we expect showers and thunderstorms that can trigger rains of .25”-1.25” with windy conditions. However, it will take the thunderstorms to get in to the upper end of the range the way we see it right now. The expectation is for the best rains still to be in central and southern Indiana. The map at right shows rain totals through midnight next Tuesday (which includes the action of tomorrow, remember). We should turn partly sunny behind the system for Wednesday the 27th and to start Thursday the 28th.
The extended period remains very active in our forecast and we are not stepping away from the potential for excessive precipitation. From Thursday the night of the 28th through Sunday the 31st, we have rain and thunderstorms coming in several waves. The heaviest action will be in central and southern again. Four day rain totals can be from 1 to 3 inches across 100% of the state. After 2 dry days to start April on the 1st and 2nd, another front brings. 25”-1” rain potential for the 3rd. A couple of models tried to back off of the heavy rains yesterday, but we are seeing no consensus that this goes away, and we want to watch to see just how everything evolves at this point.
