Pleasant Close To The Week; Harvey Questions…

Highlights:

  • Dry and unseasonably cool close to the week
  • Shower chances return
  • Watching Harvey

Can’t Ask For Anything Better…Our weather to wrap up the work week will be dominated by cool Canadian high pressure.  This will supply plentiful sunshine and unseasonably cool conditions.

A cold front will approach early next week before “washing out” over the Ohio Valley.  Shower chances will increase in association with this frontal boundary late Sunday night into early next week.  Dry conditions will return by the middle of next week along with slightly cooler than average temperatures.

Tropics: Harvey continues to dominate the headlines and rightfully so.  Devastating impacts will be dealt to Texas from a rain, surge, and wind perspective.  He will be upgraded to a major hurricane today.  It’s still far too early to know how far north Henry will eventually make it late next week before getting absorbed by an approaching trough.  Portions of the Ohio Valley are still on the table for potential rain impacts from Harvey late next week.  Stay tuned.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 0.00″
  • Rainfall: 0.25″ – 0.50″

Tuesday Storms Then Much Cooler…

Highlights:

  • Scattered storms with locally heavy rain
  • Early fall-like feel arrives
  • Dry weather returns

Cold Front Arrives…A cold front is pressing into the state today and generating unsettled weather across the region.  Widespread heavy rains fell overnight across northern parts of the state (areas just west of Lafayette have picked up 3″-4″ of rain during the past 24 hours).  Scattered to numerous showers and thunderstorms can be expected through early evening before a much drier and cooler air mass arrives tonight behind the frontal passage.

That drier and cooler regime will set the tone for the rest of the week and weekend.  High pressure will settle in and provide plentiful sunshine.  Additionally, cool, Canadian air will pour south as we progress through the second half of the week.  This will result in well below normal temperatures and conditions that will feel more like mid to late September rather than late August.

Tropics:  Harvey is likely to stage a comeback over the next few days once he emerges into the southwest Gulf of Mexico.  Folks with interests along the Texas coastline should certainly monitor Harvey for tropical implications as the weekend approaches.  An interior heavy rain/ flood threat will result, as well.

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.

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.
