Unsettled Stretch Of Weather Ahead…

Highlights:

  • Scattered storms
  • Turning cooler next week
  • Continued unsettled

Periods Of Storms In The Days Ahead…While we’ll have more dry time than not into the weekend, multiple rounds of showers and thunderstorms can be expected as we close the work week and move into the weekend.  With a moisture-rich air mass in place, locally heavy rain is possible.  Storms will reach most widespread coverage during the afternoon and evening hours through Saturday.

A cold front will sweep through the state Sunday with scattered to numerous showers and thunderstorms followed by drier, cooler air for Monday.

As we progress through next week, the region will remain in a much cooler, challenging northwest flow.  Individual disturbances will race southeast and result in continued unsettled weather as race weekend and the Memorial Day holiday draws closer.  We’ll keep a very close eye on things.  The balance of next week will be significantly cooler than average.

Upcoming 7-Day Precipitation Forecast:

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

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.

Upcoming 7-Day Precipitation Forecast:

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

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!

Heavy Rain And Flooding Update…

Unfortunately, we don’t have any changes to our ongoing forecast.  Widespread rain will continue through Friday, occasionally heavy.  By the time all is said and done, many local rain gauges will check in between 3″-4″.  Lets break it down:

This morning’s radar shows rain intensifying across central and western portions of the state this morning, especially west of I-65.

7:30a radar snap shot.

Plan on steady rains to continue today, periodically heavy.  If you live near a body of water, remain aware of current water levels.  Significant rises will begin to take place this afternoon as the periodically heavy rains add up.

12p forecast radar.

Widespread rain will continue overnight into Friday morning.  As low pressure slowly tracks northeast, we think a “deformation zone” will set-up shop across central Indiana Friday.  Within this large band of rain, multiple intense rain bands will pivot through central Indiana.  Flood concerns will remain high through Friday.

We should finally get into drier air Friday night before one last round of showers pushes southeast across the state Saturday morning.  As of this update, we bracket the 4a-10a timeframe for renewed wet weather.  By Saturday afternoon, drier air should win out and result in a much more favorable forecast Saturday night into Sunday.

By the time all is said and done, widespread 3″-4″ storm totals are expected, and will most certainly lead to flooding.  Even localized 4″+ amounts can be expected within areas where the heaviest rain bands persist.

In closing, as drier air begins to arrive on the scene Saturday evening, much cooler conditions will result in areas of frost into early next week.  Lows in the lower to middle 30s will be common Sunday and Monday mornings across central Indiana.

Flooding Concerns Return…

Highlights:

  • Heavy rain returns
  • Unseasonably cool
  • Drier weather returns late in the weekend

Live Near A Body Of Water? Keep An Eye On The Level…Central Indiana will deal with an extended period of rain, occasionally heavy, tonight through Friday afternoon.  With saturated soils in place, an additional widespread 2.5″-3.5″ (with locally heavier amounts) between now and Saturday morning, flooding concerns are very high.  As the lead off states, please remain aware of water levels if you live near a creek, stream, or river.  The other aspect of this storm will be unseasonably chilly air and gusty easterly winds that will shift to the north Friday night into Saturday.

The weekend will provide a drier trend, but the improvements will be slow to occur.  Showers remain in our Saturday forecast before drier air finally wins out Sunday with sunshine.  The worry once to Sunday and Monday mornings will be the potential of frost and freeze conditions- especially in communities away from downtown.  Remember, no planting around these parts until after Mother’s Day!  😉

Shower chances return by the middle of next week!

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 0.00″
  • Rainfall:  3″ – 4″
