Central Indiana will still see some isolated showers and storms develop this afternoon, primarily in our eastern locations closer to the departing upper level low. But the bulk of the day will remain partly cloudy and dry, a welcomed chance for many of us! Skies stay partly cloudy again tonight and it will be muggy outside. Low temperatures will only fall into the upper 60s.
We’ll start off Monday dry, warm and muggy across the state. Rainfall should hold off past the noon hour with models only picking up isolated showers approaching our northwestern counties in the early afternoon hours. It’s during the mid afternoon and evening hours that scattered showers and thunderstorms will start passing through the state. We are not expecting any severe weather at this time on Monday but any storm can producing frequent lightning and possibly some heavy rain too. Heat will also build on Monday with highs in the mid to upper 80s in some spots! This is a big jump from what we saw over the weekend. Temperatures will be warmest in our western counties where the heat ridge tries to sneak in for the day.
This same heat ridge between the Rockies and the Ohio Valley will build for the coming workweek and several rounds of showers and thunderstorms will form along the edges. This should easily bring storms in Central Indiana both Tuesday and Wednesday. But unlikely our storm activity over the last several days, these storms could pack more of a punch. The Storm Prediction Center already has an eye on the Tuesday stronger storms and includes a “slight risk” just to our west in Illinois. We are still several days out, so this risk area could move to eventually include portions of our state.
We need to plan on scattered storms on Tuesday and more likely storms on Wednesday. We could definitely see some heavy rainfall out of this system with around 2” of moisture aloft. This means that a tropical atmosphere is still in place and slow-moving storms could easily dump torrential rainfall again.
Cooler and drier air will return after the cold front passes early Thursday morning. This means that the humidity will break and sunshine will return. For those of you sick of rainfall, look forward to Thursday afternoon and throughout the coming weekend. High pressure will take over and this ensures several dry days in a row.
