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″

Quick Thursday Morning Comment…

Good morning, friends!  Temperatures this morning are in the lower 50s for many across central Indiana as our “hint” of fall continues to wrap up the month of August.  I…

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.

Upcoming 7-Day Precipitation Forecast:

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

The Week Opens Quiet Before More Unsettled Times Return…

High pressure will remain in control of our weather pattern through the early portions of the new week.  This will supply continued dry conditions, along with plentiful sunshine.  Humidity values will remain comfortable as we open the work week before turning increasingly muggy as midweek nears.

High pressure will keep us dry through early week.

As high pressure moves off to the east, a southwesterly air flow will help moisture return to the state by mid and late week.  As a cold front enters the picture, overall coverage of showers and thunderstorms will increase and become scattered to numerous.  We’re not expecting any sort of all-day rains, but chances of getting wet from time to time will go up Wednesday through Friday.

Thunderstorm coverage increases mid and late week.

Rainfall totals should fall in the 0.50″ to 1.00″ range for most, but there will be a few folks who pick up locally heavier amounts the second half of the week.

As of now, we think the cold front will pass Friday evening and set-up another pleasant weekend with seasonable temperatures.  The stretch of gorgeous August weekends’ appears to roll along.

What else we’re working on:  With us about to flip the page to the second half of August, thoughts continue to shift to the upcoming meteorological fall and winter seasons ahead.  Early data paints an “intriguing” look, complete with high latitude blocking and neutral ENSO look.  Winter enthusiasts should like the look overall as this will have an impact on the prospects of cold getting going earlier than recent years past.  Much more on fall and winter in the weeks ahead…  The other big item of interest has to do with the tropics.  A new disturbance will traverse the MDR (Main Development Region) this week and given the overall upper level pattern over the CONUS, we’ll have to keep an eye on the East Coast Weeks 2-3.

Considerable Cloudiness To Open The Work Week…

Highlights:

  • Mostly cloudy start to the work week
  • Another cold front moves in
  • Turning cooler late in the weekend

Comfortable Late-Summer Week Ahead…Talk about a bust of a Sunday forecast on our part.  Dry air and lack of forcing resulted in steady rains remaining across southern parts of the state.  With the exception of a couple of brief showers, central and northern portions of the state remained dry most of the day.

While we’ll remain with mostly cloudy skies today, most of the region will once again remain free of any rain.  The exception will be across southeastern Indiana where steady rains have been falling this morning.  That will continue to move east into Ohio as we push forward.  Otherwise, drier air will arrive tonight and set the stage for increasing sunshine Tuesday and Wednesday.  With low humidity and below normal temperatures, both days will be great to spend time outdoors, or perhaps a trip to the Indiana State Fair is in order?

Moisture will begin to return by Thursday and with an approaching cold front, scattered showers and thunderstorms will be with us through the weekend.  As of now, most widespread storm coverage is expected late Saturday into Sunday morning.  We’ll turn significantly cooler than normal (yet again) early next week.

Tropics:  As expected in August into September, the tropics are turning increasingly active.  This morning, Tropical Storm Franklin continues to grab headlines as he is becoming more organized and positioned to impact the Yucatan today through Wednesday.  From there, Franklin is anticipated to move into the southern Gulf of Mexico Wednesday.  With very warm waters and a low shear environment, Franklin should strengthen yet again before making a second landfall late in the work week along the east-central Mexican coast.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 0.00″
  • Rainfall: 0.50″ – 1.00″
