We had a humid start to the weekend with sticky conditions across Central Indiana. It actually felt like a summer day after what has been a very unusual stretch of cool weather in late July. The cold front that brought in the rain early Saturday morning has left us with a north wind tonight and dry conditions. This north wind will not only help cool us down overnight but it will also usher in drier air. Dew points should fall from the mid 60s like we saw Saturday afternoon to the mid 50s for Sunday. This will most certainly bring back the comfort factor and another good excuse to open the windows and enjoy some fresh air!
Temperatures will be cooler on Sunday with highs only expected in the mid to upper 70s across the state. A wind from the north and mid-afternoon clouds should help to keep things below the 80s degree mark easily. But it will definitely be a comfortable day!
We’ll see several rounds of low pressure passing through the state early this coming week. The first area of low pressure arrives to the state on Monday. It’s still questionable as to how much rain we’ll get out of this first system, but for now I’m including a 30% chance for showers and storms for Monday afternoon. The atmosphere won’t be terribly moist ahead of this system so it will take some time before this fully materialized into rainfall. Trace amounts up to .10″ of rain should be about it on Monday.
Another system of low pressure will be heading in from the Great Plains on Tuesday night/Wednesday and this system has a better chance to not only give us rainfall but heavy rainfall. Isolated showers and thunderstorms will be possible Tuesday but the better chance is really that night and throughout Wednesday. Rain is likely for Wednesday as the system arrives but the path could keep rain around for several hours. This would lead to higher rainfall totals. Three different weather models that I looked at tonight had us around or just over 1″ or rainfall with the new Canadian model at 2″ of rain. Obviously, this will be tweaked in the days ahead and we’ll have more as those numbers fine tuned. The heavier rain solution is dependent on this low pressure tracking right through the middle of our state.
