Unsettled Open To The Week And Looking Towards Next Weekend…

As we type this Sunday evening a few strong storms have developed across east-central Indiana.  If your travels take you east this evening, a couple of these storms have been producing large hail and strong winds.

Otherwise, a stalled frontal boundary remains draped across the Ohio Valley and will serve as the focal point for additional shower and thunderstorm development through the early stages of the week.  Rainfall coverage will likely be most widespread Monday, and come in a couple waves: Monday morning into early afternoon and again Monday evening.

By the time all is said and done late Monday night and early Tuesday, expect widespread rainfall totals between 0.50″ and 1″ with locally heavier amounts where the stronger storms track.

High pressure will build into the region through the midweek stretch and result in increasingly sunny and pleasant conditions.  With a drier air mass in place, overnight lows will fall into the 50s through the midweek period.

Our attention will then shift to the threat of active times for the Memorial Day weekend, including the 102nd running of the Indianapolis 500.  After a mostly dry Friday, shower and thunderstorm chances will be on the increase Friday night through the weekend, continuing into early Monday as of now.  While it won’t rain the entire time, it might be a good idea to have a “plan B” in mind at times for the busy upcoming weekend.  Models like the idea of a rather significant, albeit likely brief, cool down to close the month…

Timing Out Weekend Rain And Storms; Looking Towards Memorial Day Weekend…

Scattered showers and a couple of rumbles of thunder will be most numerous this morning into the early-mid afternoon hours before briefly drier conditions build in this evening.

Our attention will then shift to the potential of strong thunderstorms late Sunday.  Higher resolution guidance suggests storms will begin to rumble into western Indiana late Sunday evening (around 9p to 10p) before tracking east into the overnight hours.

With a stalled front nearby, shower and thunderstorm chances will remain in our forecast into the middle of the week.  While it won’t rain the entire time, unsettled conditions will remain into Wednesday before high pressure provides drier conditions Thursday and most of Friday.

Thinking as of now is that a new storm system will approach next weekend, which would deliver a return of unsettled weather late Friday, continuing through the all-important Memorial Day and Indy 500 weekend.  We obviously still have plenty of time to watch things unfold over the upcoming week and will get more specific as time grows closer.

A new storm system could result in an unsettled Memorial Day weekend around these parts.

From a temperature perspective, the upcoming 6-10 days will run well above average, maintaining the warm May theme.  Looking out further, there’s the possibility that the last couple of days of the month could trend cooler behind the Memorial Day weekend storm.

Pleasant Weather As We Close May…

Highlights:

  • Pleasant weather ahead
  • Storm chances return to close the week
  • Drier trend this weekend

Happy Memorial DayBefore we look forward to the rest of the week, a secondary cold front will pass this evening and a couple of showers could bubble up as sunset nears.  These won’t be a big deal and should be quick movers with cooler, drier air building in overnight.  That will set the stage for a very pleasant midweek stretch, temperature-wise.  Another round of showers are possible Wednesday, but more dry time can be expected than wet.

More widespread showers and thunderstorms will return as we close the work week and open the weekend.  A cold front will push southeast Saturday morning and we’ll turn briefly warmer and more humid Friday with increasing thunderstorm chances during the back half of the day.  Once the front slides to our south, drier and cooler air will quickly return.  From this distance the weekend doesn’t look bad, at all.  Unseasonably cool, dry air will continue next week.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 0.00″
  • Rainfall:  0.50″ – 1.00″

More Dry Time Than Not, But Keeping A Close Eye On Storm Chances…

Highlights:

  • Much more dry time than stormy
  • Timing storm chances
  • Unseasonably cool open to June

Best Storm Chances Arrive Overnight…Low clouds and areas of fog should dissipate and give way to partial sunshine as we progress into the late morning and afternoon hours.  A warm and humid feel will develop this afternoon.

The majority of the long race and holiday weekend will be free of any rain and storms, but we will continue to keep a close eye on the potential of more widespread storm activity:

Overnight tonight into early Sunday morning and again Sunday afternoon.

Data would place more emphasis on the potential of widespread severe weather across southern parts of the state tonight.  Damaging wind and hail are the primary concerns.  Additionally, as a cold front rumbles into the warm and moist airmass in place Sunday afternoon, additional strong to severe storms may develop.  These will be more scattered in nature when compared to the overnight round of storms, but any one particular neighborhood across central Indiana is fair game for getting wet for a brief time Sunday afternoon.

The cold front will sweep through the state Sunday evening and usher in a less humid and pleasant Memorial Day.  We’ll keep an eye on Tuesday into Wednesday for shower chances, but think we’ll remain mostly rain-free.  The region will be under a fast-paced northwest flow aloft and models can struggle with specifics associated with weak disturbances in that northwest flow.  The next chance of storms arrives Friday, along with a warmer feel.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 0.00″
  • Rainfall: 1.00″ – 1.50″
