Looking At The Week Ahead: Relatively Quiet Open Gives Way To Active Times…

High pressure will dominate our early week weather.  With the exception of an isolated shower or thunderstorm across eastern portions of central Indiana this afternoon, most should remain rain-free through the daytime hours Tuesday.

High pressure will keep the majority of the region quiet to open the new week.

The pattern will begin to turn busy once again as we move into midweek.  An approaching storm system will increase shower and thunderstorm chances late Tuesday night through Thursday.  While it won’t rain the entire time, locally heavy downpours are expected at times during the midweek stretch.

Most of central Indiana can expect to pick up 0.75″ to 1.25″ of rain during the aforementioned period, but there will be locally heavier totals.

Looking towards next weekend, forecast models generally agree on active times continuing, but disagree on the important specifics.  We’ll go with a “blend” right now and increase rain chances again Saturday and Sunday- after a briefly drier Friday.  The ranges are anywhere from a flood threat, such as the European currently suggests, to typical scattered showers and thunderstorms, per the latest GFS.  Stay tuned as we continue to fine tune through the upcoming week.

This is all part of a continued active weather pattern that will likely produce above normal precipitation as we close out the month and look towards September…

Unsettled 24-36 Hours And Looking Beyond…

A cold front is slowly sinking south and will feature a weak wave of low pressure that will track along the boundary Tuesday.  The end result spells for increased chances of showers and thunderstorms across central Indiana over the upcoming 24-36 hours.

Initially, we expect an area of thunderstorms to push south and potentially impact north-central portions of the state later tonight.  The latest high resolution NAM forecast radar gives us an idea what the radar may look like late tonight- just after midnight.

Some of the storms across the northern third of the state may “pulse” to severe levels this evening, including the potential of large hail and damaging winds.  (This complex will weaken as it surges south later tonight).

As we turn our attention to Tuesday, scattered to numerous showers and thunderstorms are expected, especially during the afternoon and evening hours.  A few strong storms are possible, including locally heavy rain.

Eventually, drier times will return by mid-week.  Beforehand, most central Indiana rain gauges should receive somewhere between 0.50″ to 1″ of rain.  With a rich, tropical airmass in place, there will be some locally heavier totals.

As the cold front moves south during the midweek stretch, drier times will return Wednesday and Thursday.  With that said, the drier regime won’t last long, as a cut off upper low “mucks” things up over the weekend.  While it certainly won’t rain the entire time, daily rain chances will return late Friday, continuing throughout the weekend.  There’s no need to cancel any outdoor plans, but have the rain gear handy, as you’ll likely need it at times throughout the weekend.

Speaking of rain and overall unsettled times, the pattern sure looks active around these parts into the mid and longer range.  More on that in future updates…

Mostly Dry Weekend; Active Times Return Early Next Week…

A summer-like feel will return as we move through the weekend. While the heat and humidity won’t be excessive by any means, you’ll certainly notice a different feel when compared to the cooler air we’ve enjoyed over the past 10 days, or so.  We forecast highs in the mid-upper 80s with plentiful sunshine through the weekend.  While an “isolated” thunderstorm is possible, most will remain rain-free until early next week.  That said, best rain and storm chances will be confined to northern Indiana Thursday evening and forecast radar products are picking up on a skinny line of showers and thunderstorms.

The weekend will be highlighted by plentiful sunshine with only isolated storm coverage and an increasingly muggy feel.  Note the southwest air flow returning around an area of high pressure off the East Coast and our next approaching storm system to the northwest.

That storm system will settle south and begin to impact central Indiana early next week with storm chances increasing Monday into Tuesday.  With rich tropical moisture in place, locally heavy rain will be likely as the front moves in.

Models are in overall agreement of additional significant rainfall early next week (widespread 1″ to 2″).
