Hot, Humid Weather Gives Way To Much Cooler Times…

Highlights:

  • Hot and humid open to the week
  • Scattered early week storms
  • Much cooler and less humid times loom

Time To Sweat…A hot and increasingly humid airmass will be with us as we open a new week.  While most of the upcoming 24-48 hours will remain rain-free, we will mention chances of an isolated to widely scattered thunderstorm Monday.  Most will remain free of rain and storms, but those lucky folks who do find themselves under a storm Monday can expect to pick up a quick 1″ of rain.  Better overall coverage of showers and thunderstorms will develop late Monday night into Tuesday.

Typically, a pattern change such as what we’ll undergo this week (summer-like to early fall-like) would yield widespread showers and thunderstorms.  However, a look at short-term, higher resolution data isn’t particularly “excited” about widespread significant rainfall across central Indiana.  We expect a weakening complex of thunderstorms off to our northwest to drift southeast Monday night.  Depending on how quickly this complex weakens will determine rainfall amounts, locally.  Additionally, it’s very possible this weakening storm complex will serve to limit new thunderstorm development Tuesday as the cold front moves closer.  We do note high resolution data places emphasis on northern and southern parts of the state for heaviest rains and it’s tough to disagree with that idea given what we’re looking at right now.  Stay tuned.

Regardless of the rain and storm situation, locally, we’ll all turn significantly cooler by midweek.  In fact, temperatures will grow cool enough to feel like mid-September.  Dry conditions will carry us into next weekend.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 0.00″

Warm And Muggy; “Splash And Dash” Storms…

Highlights:

  • Scattered storms
  • Saturday showers
  • Surge of heat ahead of a late week cool down next week

More Dry Time Than Stormy…A warm and moist southwesterly air flow will have things feeling quite muggy today.  This tropical feel will also help fuel scattered thunderstorms by evening, continuing into tonight.  While everyone won’t get wet today, those that do have the potential of picking up a quick 1″ in a short period of time.  A cold front will cross the state Thursday and will keep scattered showers and thunderstorms going.  While this isn’t a uniform soaking, we’ll take what we can get as things have been bone dry around these parts lately.

After a quiet and slightly cooler Friday, an upper level disturbance will deliver another round of showers and embedded thunderstorms Saturday.  Dry weather will return to wrap up the weekend Sunday.

Looking ahead, a surge of heat, albeit brief, will have things feeling quite toasty around the Mid West early next week.  We think we flirt with, or exceed, the 90° mark both Monday and Tuesday.  Thunderstorms will increase Tuesday as a cold front drops in from the northwest.  Behind the front, data still paints a much cooler regime for the second half of next week; fall-like!

Classic Mid-August Weather…

Highlights:

  • Dry open to the work week
  • Unsettled times return
  • Cooler air heading into the weekend

Storm Chances Begin To Increase…While southern portions of the state will get wet today, dry air should result in a rain-free Monday here across central Indiana.  That will begin to change later this week as moisture returns and that muggy summer feel develops for midweek.  In addition to the increasingly humid nature to our airmass, a cold front will approach from the west.  Coverage of storms tomorrow should remain few and far between (isolated), but overall coverage will increase Wednesday into Thursday (scattered to numerous).

The cold front will sweep to our east Thursday night and result in a beautiful close to the work week, complete with cooler temperatures and lower humidity levels.  The weekend will feature a disturbance dropping in from the northwest and this will be sufficient enough to kick up scattered showers and thunderstorms Saturday afternoon and evening before dry times return Sunday.

Gorgeous Weekend; Humidity Returns Next Week…

Highlights:

  • Beautiful weekend dialed up
  • Humidity returns
  • Scattered storms late week

Refreshing Conditions Continue…A cold front settled south of the region last night, allowing drier and slightly cooler air to filter in during the overnight.  That sets the stage for the weekend as we can expect dry and refreshing conditions, along with below average temperatures.

Dry skies will continue into the new work week, but humidity will slowly begin to increase once we get to midweek.  A southwesterly air flow will develop ahead of our next storm system that will deliver scattered thunderstorms by Thursday.  Shower and thunderstorm chances will continue Friday morning, however, early indications suggest next weekend is also dry.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 0.00″
  • Rainfall: 0.25″ – 0.75″

Cool August:  The month has opened impressively cool with a CONUS average anomaly of – 2.75° through the 10th.  More specifically to Indianapolis, we’re running 3° below normal through the 11th.

Scattered Storm Chances Return…

Highlights:

  • Scattered t-storm chances return
  • Mostly dry, pleasant weekend
  • Rain chances return early next week

Frontal Boundary Moves In Friday…Another sunny, pleasant late-summer day is on tap before a cold front approaches late tonight. This frontal boundary will be responsible for creating scattered thunderstorms Friday across central IN.  Current indications suggest rain won’t be widespread or particularly heavy, but don’t be surprised by a local downpour or two as we wrap up the work week.

Dry and pleasant weather will return over the weekend, complete with plentiful sunshine.  Our next storm system approaches Sunday night into Monday with the potential of more widespread rain.  With that said, there’s considerable model disagreement with regard to overall rain coverage and amounts Monday (European is the most aggressive with widespread rain).  We’ll go with a blend of the two for now (scattered thunderstorm chances) and hope for better agreement later today.  We’ll provide updates after taking a good look at 12z data.
