Scattered light showers are scooting across central Indiana this morning but our airmass still will take some time to saturate throughout all levels. As such, we don’t expect widespread heavy rain and embedded thunder until we get into the new work week. You’ll notice an increasingly muggy time of things Monday and Tuesday. Note the Gulf connection below. This will send dew points well into the 60s. Temperatures will also be on the rise (low/mid 80s) which will have things feeling very much like summer by mid and late week.
The transition of air masses will lead to a stretch of unsettled weather. We note model guidance has trended wetter over the past 24 hours for immediate central Indiana. We’re now honing in on Monday evening into Tuesday morning offering up the most widespread heavy rain and embedded thunder. Locally heavy rain will be possible during this timeframe. Some central Indiana rain gauges may pick up more than 2” of rain during this time period. Widespread 1.25” to 1.75” amounts can be expected.
Scattered, “splash and dash” storms will remain in our forecast into midweek before high pressure nudges itself into place and promotes a drier regime for the 2nd half of the week.
