Sunshine dominates today and tomorrow. High pressure moves over the eastern corn belt. South winds will develop and that should take temps back to above normal levels. However, we are making some tweaks to the forecast for Thursday, bringing better chances for showers into the picture. Clouds build early Thursday, and then scattered showers end up with about 60% coverage. Totals will be up to .25”, but still generally will be light. This will be priming the pump for Friday and Saturday. On Friday, Scattered showers a few hundredths to .3” or .4” with 70% coverage. Then we see better organized and stronger intensity action from overnight Friday night through Saturday. This will bring an additional .25”-1” to 90% of the state. All action will be done by Sunday morning. Combined, that means we see three day rain potential at half to 1.4” over 80% of the state, with the remaining 10 percent getting wet, but likely falling short of the half inch lower threshold. The best chance of seeing the lower end of the range will be in central to southern Indiana. The map shows cumulative precipitation through Sunday morning.
We should turn out dry for Sunday, although clouds may take a while to break up in spots. WE see colder air coming in overnight Saturday night into Sunday as well. AT this point in time, we think moisture will be gone before the coldest air is here, so while we are keeping snow potential on the backburner for now, it could easily be cold enough for it. We will be below normal for Sunday. Then we start to see moderation as we kick off next week. We should be sunny and dry for Monday the 1st through Wednesday the 3rd. We can’t rule out some light rain on Thursday the 4th, bringing .1”-.6” and 80% coverage.
The rest of the extended period is unchanged at this time. Scattered showers linger through Friday the 5th, with 60% coverage and amounts up to .4”. After a dry start to the following weekend, we have rain back form Sunday the 7th and Monday the 8th. Combined totals can be from .35”-1” over 100% of the state, although rains for Monday the 8th will be mostly from I-70 north. Drier weather completes the extended period for the 9th and 10th.
