A little bit of minor moisture moves into the northern part of the state today, creating a north vs. south kind of set up. From I-70 northward, we have to be on the lookout for a few hundredths of an inch of rain up to about three tenths, with coverage at 80% of the region. South of I-70, we get nothing today. This is an offshoot of a system coming out of the upper Midwest and moving across the great lakes.
A warm front lifts north across the state Friday, bringing scattered showers in over the northern half to third of the state, but coverage will be significantly lower than tomorrow’s action. Then we continue to see scattered showers for the Weekend, with Sunday still looking slightly better for amounts and coverage. All told, from Friday through the weekend, we will keep our combined rain estimates at .25”-75” with 70% coverage.
Monday and Tuesday remain dry and she should see a decent amount of sunshine. The front for midweek next week on Wednesday remains stronger this morning, with rain totals of .25”-1”. WE think there can be a few areas that could go higher in southern Indiana, if a second wave of action spill into the state overnight next Wednesday night into Thursday. Coverage of rain from that system will be at least point, 80%.
A final system works in late next week and straddles into the start of the extended window bringing rains of .25”-.75” with 80% coverage for late the 21st into the 22nd. A very powerful system also is in for the 25th-26th with rains up to 1 inch. However, behind that system, we see a strong high and potential for an upper level ridge to support it for the last of the month. Other models suggest colder than normal air will be in for that period, but we are not on that bandwagon yet. We think talk of a cold finish to April is overdone at this point, but are alerting you to it in case you hear someone else advancing that theory.
Temps for most of the upcoming period will be normal to above normal, with a large percentage of the period having high temps of 3-10 degrees above normal for this time of year.
