Temperatures will run slightly above normal (for a change) across a good chunk of the country through the upcoming 7 days. Only exception to this will be across the South.
The Heartland will be in the cross hairs of a multi day heavy rain event this week. Meanwhile, from the central and Ohio Valley and points east we’re looking at a continued dry stretch.
Central Indiana can expect between 1” and 1.5” of rain in the week ahead on average.
This will be an active week for the Plains as a multi day severe weather episode compliments what will also be an evolving flood risk.
Forecast Period: 05.15.21 through 05.22.21
Change is ahead over the upcoming week towards a pattern more typical of what we’d come to expect this time of year. We’ll say goodbye to the cool, crisp air in the short term period and replace it with an increasingly warm and muggy feel of things. Scattered showers and thunderstorms will accompany this transition. While the chances of widespread heavy rain are diminishing, we will see scattered to numerous showers and storms during the early and middle part of the work week. These will be of the “splash and dash” variety and certainly won’t require any cancellation of outdoor plans. High pressure appears like it’ll nudge its way into the region Wednesday night, allowing us to enjoy another stretch of dry conditions as we close the work week and head into next weekend.
Temperatures will moderate from the unseasonably cold conditions as of late. We’ll make a run for 80° by Tuesday here in central IN.
Above normal rainfall is expected in the week ahead from the mid MS Valley and Gulf Coast into the Ohio Valley and Great Lakes.
We forecast most central IN rain gauges to receive between 1.75″ and 2.25″ in the week ahead.
A new spring storm will emerge out of the Plains Tuesday and likely ignite a round of severe weather throughout tornado alley.
Forecast Period: 04.24.21 through 05.01.21
A relatively weak storm system will lead to plenty of clouds today and a couple of light passing showers (better chance of steadier rain downstate). This system will blow by to our east tonight and allow a drier air mass to build into the region as we move through the 2nd half of the weekend, complete with a return of sunshine! Enjoy the sunny and much warmer open to the week as significant changes await by Wednesday. Before this, a strengthening southwesterly air flow will push high temperatures into the lower 80s Tuesday! Attention will then shift to a complex and multifaceted storm system that will deliver heavy rain and thunderstorms (potential present for a couple stronger storms midweek that we’ll continue to monitor) in rounds Wednesday through Friday. While it won’t rain the entire timeframe, periods of heavier rain can be expected. We’ll dry things back out heading into next weekend.

A cooler trend will develop this week from the Plains into the Ohio Valley. Meanwhile, unseasonable warmth will hang on a couple more days across New England.Below normal precipitation is expected this week across a widespread chunk of the Lower 48. One major exception to that will be found along the Gulf Coast.
Rainfall totals should fall within 0.25” and 0.50” for immediate central Indiana this week and most of that will come today.
Another round of severe weather is expected across Florida today, unfortunately impacting spring breakers. All in all this will be a quieter week on the severe front as the cooler pattern settles in.
Forecast Period: 04.11.21 through 04.18.21
Central Indiana will continue to feel the affects of the low pressure system that resulted in periods of storms yesterday through the remainder of the weekend. A rather persistent light to moderate rain is expected today along with gusty winds and cooler air. This system will pull east of the region Monday and allow for drier air to return. The bulk of the remainder of the forecast period looks dry and seasonably cool. We’ll continue to keep an eye on upper level energy scooting to our east midweek. This is expected to result in a few instability-driven showers for our friends across northeastern IN into OH, but continues to look like it’ll just miss central IN.
Frosty conditions are still possible Thursday morning, especially if we can clear out any lingering clouds from the aforementioned upper energy. The next opportunity for better coverage of light showers won’t come until next weekend. Overall we only expect 0.25” and 0.50” of rain in the week ahead- most if not all of which falls today.
