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.

Rain And Storm Chances Return…

Highlights:

  • Frosty start
  • Rain chances return
  • Dry and pleasant close to the week

Wet Weather Returns…Bright and sunny conditions are in place as we open up a new work week, and many are awaking to frost out the door this morning, as well.  Light winds, dry air, and clear skies allowed temperatures to plummet into the lower and middle 30s for many central and northeast IN neighborhoods overnight.

Clouds will increase later today and showers will arrive tonight.  We’ll introduce thunderstorms into the mix Tuesday as a frontal boundary begins to settle south.  That frontal boundary will begin to stall near the region midweek and additional waves of showers and thunderstorms will impact the region (especially the southern half of the state) through Thursday.

Drier weather will return to close the week and we expect a very pleasant start to the weekend.

A new weather maker will deliver a shower chance Sunday.

Upcoming 7-Day Precipitation Forecast:

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

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 And Storms Ahead; Cooler Week On Deck…

Highlights:

  • Widespread rain and strong storms today
  • Falling temperatures, windy, and wet Monday
  • Midweek storm brewing

Flooding Concerns Remain High…Another slug of moisture will lift north through central Indiana this afternoon into the nighttime hours.  Locally heavy rain will result in big flooding concerns as saturated soils are in place and many creeks and streams are already out of their banks.  Throw in an additional 1″-2″ with locally heavier totals and you have the makings of a dangerous flood situation into early week.  If that wasn’t enough to be concerned about, we’ll also have to watch how things evolve closely this afternoon for the potential of severe thunderstorms.  Damaging straight line winds are of greatest concern.

We’ll transition to a much cooler regime to open the new work week with gusty winds and showers continuing.  Temperatures will fall through the 50s during the day.  Jackets will be required!

Tuesday will provide a brief break from the wet weather and we should also introduce some sunshine for a while.  Unfortunately, we won’t have much time to dry out as a wet, windy, and chilly storm is brewing Wednesday evening into Thursday.  Widespread rain (some heavy) will combine with a raw easterly wind and temperatures in the 50s to lead to a rather miserable Thursday.

While shower chances remain early Friday, the theme heading into next weekend is a drier one and we should finally enjoy very pleasant weather by Saturday.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 0.00″
  • Rainfall: 1.50″ – 3.00″

Gearing Up For The “2nd Half…”

Central Indiana has enjoyed a well deserved break in the rain and thunderstorms this afternoon, but, unfortunately, stormy times will return tonight.  With an increasingly moist air mass in place (warm front is currently draped across central IN and slowly lifting north), renewed heavy rain is expected tonight into Sunday.  Dew points will approach 70° and precipitable water values (PWATs) will periodically reach 2″ between this evening and Sunday night.  With that kind of moisture content in the atmosphere, locally heavy, flash flood-producing, rains are a “lock.”  Should you live near a creek, stream, or river, please keep abreast of water levels into early next week and have a plan in place to move to higher ground.

The Storm Prediction Center paints a “Slight Risk” of severe weather across central and southern Indiana tonight.

We think an eastward-advancing line of thunderstorms will blow into central Indiana later this evening (between 9p and midnight).  Some of these may reach strong to severe levels with damaging straight line winds of greatest concern.  Additionally, torrential downpours will occur within this line of storms.

Overall coverage of rain and thunderstorms should diminish Sunday morning before ramping up and increasing in overall coverage and intensity (yet again) Sunday evening and night.  In fact, we may be looking at another severe weather episode Sunday night- again with straight line damaging winds of greatest concern.  By the time all is said and done we expect an additional 1″-2″ of rain across central Indiana with locally heavier 3″+ amounts where storms train over the same area.  Obviously, with saturated soils in place across central Indiana, this amount of rain will create flood concerns into Monday morning.  By the time we get to Monday, the big weather story will be strong and gusty NW winds, much cooler air (falling temperatures through the 50s) and nuisance-level showers.

Another heavy rain maker looms Thursday and we’ll cover that in our updated 7-day later tonight or Sunday.
