We have to kick up the arrival of our next system here today. Moisture is expanding quickly across the Corn Belt, and we can see showers developing in western parts of the state already at mid-morning, all the way through this afternoon. The action starts in west central Indiana and southwest parts of the state but spreads north this afternoon to encompass parts of NW Indiana by sunset. The rains then continue overnight tonight and tomorrow but look to lift more northe3ast. That means we can see some parts of southern Indiana, particularly southeast Indiana, missing out on the rains. We are keeping rain totals at .25”-1”, but dropping coverage to 70% of the state, and it may actually be less than that. The best rains will be in northern Indiana, particularly NW parts of the state. The above map shows rain potential through the end of the day tomorrow.
Behind this next system, we are dry Thursday through Saturday with sunshine, normal to above normal temperatures and some good breezes developing. We like strong southwest winds over the state for Friday and Saturday, providing some good drying.
Our second system moves in a little sooner as well, with rains now developing for Saturday night and Sunday. The initial rains there only affect the northern third of the state, mostly from SR 28 northward. This will be very similar to a warm front set up, with plenty of warm air overrunning the frontal boundary and causing long, drawn-out rains north of the front, but nothing south. So, in northern areas, we can see rains of .25”-1” with 80% coverage. But, south of SR 28 we see nothing for Saturday night or Sunday. A cold front finally comes through Sunday overnight bringing .1”-.4” to 90% of the state.
Next week still looks dry all week. Sunshine will combine with near normal temps. Good drying is expected. The extended period still features one good frontal set up. It should work in around the 21st over the state, bringing up to .75” and 80% coverage set up.
