Steamy Thursday Ends Stormy…

The Storm Prediction Center has placed southwestern Indiana under a Slight risk of severe weather, with extreme southern Indiana now included in an Enhanced risk.

Upper level energy will push east this afternoon and combine with an unstable air mass, along with unseasonably hot and humid air (highs today will reach the lower 90s across the southern half of the state with dew points around 70°), resulting in explosive thunderstorm development this evening.  Storms will rumble east during the nighttime hours before exiting off to the east and diminishing during the early morning hours.

We target the time frame of 6p to midnight for greatest storm coverage and the possibility of severe weather.  While the greatest threat of severe is just south of the city, itself, I think all of central IN is in play for the possibility of strong to severe thunderstorms tonight.  In addition to locally heavy rain, stronger storms could pose a damaging straight line wind threat along with large hail.

A couple of storms may still fire Friday afternoon in the warm and humid air mass, but a boundary will pass Friday evening, allowing less humid air to arrive Saturday.  On that note, even cooler and less humid air awaits early next week.

Still Warm, But Much More Active…

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.
