Weekly #AGwx And Severe Weather Outlook…

Updated 06.06.21 @ 8:28a

The upper pattern this week will feature a dominant upper ridge across the northern tier, centered over the Great Lakes region. Meanwhile, a stubborn upper low will move slowly northeast out of the southern Plains early and mid week.
The immediate western seaboard will run below to well below normal this week, while the upper Plains into the Great Lakes run well above average.
Well above normal rainfall can be expected through the period across the Ohio Valley, TN Valley, and Mid Atlantic regions.
We forecast between 1.5″ and 2″ on a widespread basis across central IN in the upcoming 7-day period, but there will be locally heavier amounts with this setup.

Forecast Period: 06.06.21 through 06.13.21

Our weather pattern will be dominated by a stubborn upper low moving slowly northeast out of the southern Plains. Eventually, this upper low will get entangled in the westerlies and begin to lose influence on our weather towards the tail end of the week. Before that, we’ll notice a rather marked difference in the type of airmass this week compared to what we’ve seen of late. A deep tropical flow, straight out of the Gulf of Mexico, will bring moisture-rich air into the Ohio Valley, including dew points that will approach the oppressive level (65° to 70°). While daytime highs will be kept cooler with the clouds and rain around, overnight lows will be elevated with such a humid airmass in place. A daily dose of showers and thunderstorms can be expected in this pattern- most numerous during the afternoon and evening hours. Given the humidity, locally heavy rain is a good bet at times. While coverage of showers and storms should slowly begin to diminish towards Friday and Saturday, we’ll still keep mention of scattered storms in our forecast into next weekend.

Change Is On The Horizon…

Updated 05.16.21 @ 7:40a

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.
