Humidity Increases; Late Week Storms Then Cooler…

Highlights:

  • Sunshine and warmth continues
  • Increasingly muggy feel develops
  • Storm chances return
  • Much cooler next week

Very Warm And Increasingly Humid…High pressure will supply continued dry conditions, along with unseasonably warm temperatures through midweek.  A southwesterly air flow will help push an increasingly muggy feel into the region by Wednesday.  “Air you can wear” will be an appropriate way to sum things up!  🙂

That increasing moisture will eventually yield better coverage of showers and thunderstorms as we move through late week into the weekend.  It certainly won’t rain the entire time, but periods of scattered thunderstorms will be with us Thursday through Monday morning.  With high moisture content, locally heavy rains will be possible.

A cold front will move through the state Sunday night and Monday and result in a significantly cooler trend next week.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 0.00″
  • Rainfall:  1.50″ – 2.00″

Storms Rumble In During The Overnight…

Central Indiana was blessed with a very pleasant start to the work week (despite that frosty open to the day), with plentiful sunshine and highs in the lower to middle 60s.  Unfortunately, the pleasant weather won’t hold, as changes are in the offing as early as the overnight period.  We’ll enter a rather challenging northwest flow regime over the next couple of days and periods of showers and thunderstorms will ride in a northwest to southeast fashion from time to time.

We believe greatest coverage of thunderstorms will ride into north-central Indiana during the overnight period, and bracket an arrival between midnight and 1a, with heavier rain and embedded thunderstorms increasing in overall coverage from 3a-4a.

Here are a couple images of what the radar may look like overnight: 1a and 4a.

Showers and thunderstorms will continue to impact the central portion of the state through the rush hour before storms diminish and give way to dry time early Tuesday afternoon.

Another batch of showers and thunderstorms may fire during the prime heating hours Tuesday evening and impact areas from mainly Indianapolis and points south.

Unsettled weather will continue as we push through midweek, including another round of showers and thunderstorms late Wednesday into Thursday (likely following a similar path to what tonight’s storms take).

While we’re confident on the overall setup, details with regard to timing and rainfall amounts are much less certain in this fast-moving northwest flow aloft.  There will likely be some neighborhoods that receive between 1″-2″ of rain between Tuesday morning and Thursday morning, while other neighborhoods receive an 1″, or less.  It would appear heaviest rainfall totals will paint themselves in a thin line from northwest Indiana, through central Indiana, including Indianapolis, and on into far southeastern portions of the state.

Frosty Mornings; Heavy Rain Returns Next Week…

Highlights:

  • Needed dry time
  • Frosty mornings
  • Heavy rain and storms return

Drier, But Unseasonably Cool…Much-needed dry time has arrived.  High pressure will dominate our weather pattern this afternoon through Monday, supplying dry skies.  Despite the return of the sunshine, temperatures will continue to run much cooler than average.  In fact, with drier conditions in place, overnight lows will tumble into the frosty range Sunday and Monday mornings. Cover up that tender vegetation.

Our next weather maker will arrive on the scene by the middle of next week as a frontal boundary stalls out over the region.  Unfortunately, this is a rather ominous signal for heavy rains to return.  We forecast periods of showers and thunderstorms Tuesday through Thursday before wrapping up the work week with scattered showers.  We’ll keep a close eye on the data over the next few days as additional heavy rains are the last thing we need.

More Heavy Rain Today, But Improving Conditions As We Move Into The Weekend…

After a relative “lull” in the rainfall coverage and intensity overnight, rain is expanding in coverage and intensity yet again this morning.  While there will be a rather sharp cut-off to the west, additional heavy rains are ahead from northwestern Indianapolis ‘burbs (including places such as Brownsburg, Whitestown, and Sheridan), Indianapolis, and points south and east.

HRRR simulated radar shows this rain shield nicely as we progress through mid and late morning.

Additional rainfall of 1″-1.5″ is likely from Indianapolis and points south and east with this band of rain before drier weather finally works in here this afternoon and evening.  Otherwise, expect continued windy, cold, and raw conditions today as temperatures remain in the 40s this afternoon, including wind chills in the 30s.

Looking ahead, one last batch of rain will arrive on the scene Saturday morning.

We’ll finally get rid of the rain and introduce a drier regime Saturday afternoon into Sunday, including a sunny close to the weekend.  With the drier air, overnight lows will fall to frosty levels Sunday and Monday mornings (lower to middle 30s).

More on the longer range this weekend!
