So far, May-to-date has run well above average in the temperature department (+8.5°) and below average from a precipitation perspective. While we’ll continue to run much warmer than normal through the second half of the month, we’ll begin to make up for “lost time” in the rainfall department, and that starts this week.
Daily chances of showers and thunderstorms are included in your latest 7-day and, at times, storm complexes will likely reach strong to severe levels as disturbances ride the periphery of an upper level ridge off to our south. It certainly won’t rain the entire time over the upcoming week and we’ll still enjoy more dry hours than wet and stormy. That said, for a region running around 1.5″ below average, the more active times will be a welcome sight for many. By next Sunday, we expect many area rain gauges to accumulate 1.5″ to 2.5″ of rain with locally heavier amounts.

Warmth will continue to dominate through the next couple of weeks.

For a change, above normal precipitation is expected over the upcoming week.
2.) Sunshine will develop as the day progresses Friday and we’ll notice an increasingly muggy feel through the afternoon and evening. A true taste of summer can be expected as we put a wrap on the work week, including highs in the middle 80s and dew points climbing into the mid and upper 60s.
Also note the tight temperature gradient across the state. That temperature gradient will serve as the focal point between a mostly dry central Indiana through the first half of the weekend and “busier” times across northern parts of the state into the southern Great Lakes region. Locally heavy rain will fall at times with storms for our friends “up north!” We’ll remain very summer-like here into next week.
4.) The balance of next week will run significantly warmer than normal and feature an almost daily threat of showers and thunderstorms. While there will be some “haves and have nots,” most area rain gauges should accumulate 1″ to 2″ of rain by the end of next week.

5.) Speaking of rain, the new European Weeklies in tonight, courtesy of weathermodels.com, also point towards wetter times in our future. This is encouraging as it supports the going idea shown this morning from the JMA Weeklies, CFSv2 Weeklies, and GEFS. Needless to say, despite the recent dry shift, we’re not concerned for long term moisture issues (or lack thereof ;-)).
