Unseasonably Cool; Heavy Rains…

  • Heavy rain
  • Unseasonably cool
  • Turning warmer
  • Active, stormy time later in the week

Jacket And Rain Gear Needed…The first of two rounds of widespread, soaking rains is pushing across central IN this morning.  Periods of moderate to heavy rains will develop later tonight as round two arrives on the scene.  Localized flooding is likely tonight and Monday morning.  The overall set-up is one that features a stationary front draped across the region with ripples of energy (low pressure) moving along the boundary.  In addition to the wet weather, this will also set up quite the temperature gradient across the state today.  Here across central IN, jackets will be needed all day with highs struggling to climb much out of the middle 60s.  Downstate, temperatures will zoom into the 80s with a severe component added into the mix tonight for southern IN (with the focus primarily being straight line winds).

Showers and thunderstorms will continue Independence Day, but we’re still hopeful in thinking we begin to dry things out for the afternoon and evening.  That’s great news for the fireworks and festivities planned tomorrow evening.

We begin to heat things back up and add storms into the mix for mid and late week as the region gets into an active NW flow regime.  The potential is there for a couple of rather noisy storm complexes later this week.  We’ll keep a close eye on things.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 0.00″
  • Rainfall: 3.5″-4.5″ (locally heavier amounts)

Unseasonably Cool; The Calm Before The Storm…

The morning is off to a dry and unseasonably cool start, including filtered sunshine.  Temperatures are running 15-20 degrees below normal across the state, with many central IN neighborhoods currently in the lower to middle 50s.

t0Mid and high level clouds will spread over the region today, but we’ll stay dry.  We’ll notice a lowering and thickening cloud deck by evening and this is a hint at things to come Sunday.

Screen Shot 2016-07-02 at 7.44.09 AMRain will overspread the region Sunday morning, increasing in coverage and intensity as we progress into Sunday evening.

hires_ref_indy_31Rain will turn locally heavy at times and we expect a widespread swath of 2″-3″ totals through the heart of the state, with localized heavier amounts.  Precipitable water values exceed 2″ across central and southern IN Sunday evening and will likely promote a flash flood threat.
1Most of the rain falls Sunday morning-Monday morning before drier air begins to try and work in here as Monday afternoon arrives.  As of now, we think Monday evening firework shows should be a go!

Sunday will also be a chilly day for the time of the year as temperatures north of I-70 likely remain in the 60s most of the day.

We’ll have a video update posted later this evening with fresh thoughts from the 12z model suite.

Enjoy The Dry Time While We Have It…

  • Pleasant air in the short-term
  • Storm chances Friday
  • Widespread soaker

Looking Increasingly Wet For The Holiday Weekend…High pressure will supply continued dry times Thursday, but clouds will increase during the evening and give way to scattered showers and embedded thunder Friday. This doesn’t look like a huge deal, but don’t be surprised by rain and/ or a clap of thunder to close the work week.  That said, there will be more dry time than wet Friday.

As we rumble into the long Independence Day weekend, confidence continues to increase for a widespread soaking rain to develop.  Thankfully, Saturday still looks mostly dry, but we think clouds will be on the increase late in the day, followed by rain overspreading the region from west to east as Sunday afternoon approaches.  Widespread rain should continue into Monday.  We still have questions on timing and precise placement of heaviest rains (2″+ totals), but it’s safe to say most, if not all, of the region can expect a long-duration rain event developing Sunday.  Stay tuned.  It’ll also be cool.  Areas where heaviest rains set up Sunday likely won’t climb out of the 60s.

Drier air will return late Monday into the middle of next week, but we caution that another wet weather maker appears to have eye on the region beginning next Thursday.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 0.00″
  • Rainfall: 1.5″-2.5″

Catching Up On Tuesday Night…

June to date is running warmer (+3.6°) and wetter (+0.71″) than normal in Indianapolis.


That said, drastic changes have taken place over the past 24 hours for the cooler and drier. In fact, as we write this, many central IN neighborhoods are enjoying temperatures in the lower 60s already at the 10 o’clock hour. An unseasonably cool night is in store with widespread low-mid 50s come Wednesday morning. (Anyone else craving fall)?!🍂


Highs Wednesday afternoon will only reach the upper 70s for most.


Our next chance of rain will arrive on scene to close the work week, however, moisture return still doesn’t look terribly impressive. We’ll continue advertising widely scattered coverage Friday. 


The plot thickens as we roll into the crucial Independence Day weekend. Latest data suggests a hefty rain storm will be in our general vicinity, but we caution many details have to be ironed out. Our forecast, locally, Sunday-Monday may differ drastically over a relatively short piece. Fine tuning on track, timing, and amounts will have to be adjusted.


GFS ensemble members also show the challenging times ahead.


Stay tuned! In the meantime, get those window opens and enjoy the weather!
