Cool, Damp Open To The Weekend…

As we get set to open the weekend, our weather pattern remains unchanged from the past couple of days. The Ohio Valley will continue to be dominated by a cut off area of low pressure sitting and spinning overhead. Unseasonably cool air, along with periods of showers will be the result. Similar to Wednesday, stronger showers could contain small hail, particularly during the afternoon.

Steadiest and most concentrated rain appears to come during the morning hours Friday. Here’s what the radar may look like predawn and mid morning Friday. Rain will be tracking west or southwest (pivoting around the upper low).

Additional scattered showers and embedded thunder will remain in our forecast Saturday.

In general, additional rainfall should be in the 0.50″-1″ range, but there will be isolated heavier totals under more persistent rain bands.

It’ll be a continued cool stretch with highs both Friday and Saturday in the mid 60s (at best).

The second half of the weekend certainly looks like the better of the two, but we caution that these cut off lows can be fickle and surprises can result in regards to timing. At any rate, a drier pattern will build in early next week, along with moderating temperatures.

Looking ahead, a significant storm system looms just beyond the 7-day that will require our attention in the days ahead.

Rinse And Repeat…

Continued unsettled and unseasonably cool

Rinse And Repeat Pattern…Our weather pattern will be dominated by a “cut off” upper low through Saturday. While it won’t rain the entire time, we’ll maintain mention of scattered showers and embedded thunderstorms each day. It still appears as if Friday will serve up the most widespread rain coverage. Similar to today, stronger thunderstorms could contain small hail, especially during the afternoon hours. Temperatures will remain significantly cooler than normal through the period.

A drier regime will build in late this weekend into early next week. Ridging will continue to expand as we move into mid week with needed dry time and moderating temperatures. Our next storm system appears to be slated for an arrival next Thursday. Storms will accompany the front followed by much cooler air.

Upcoming 7-Day Precipitation Forecast:

Snowfall: 0.00″
Rainfall: 0.50″ – 1.00″

Time Is Ticking On Summer-Like Feel…

A cold front has it’s eyes set on Indiana and will pass through the state Monday morning. Ahead of the front, scattered thunderstorms that we’re seeing on radar this evening (around 8p as we type this up) will transition into more widespread showers and embedded thunder during the wee morning hours Monday as the front moves through.

In general, rainfall totals should be around one half inch, but we do note some locally heavier totals can be expected where evening thunderstorms track.

Storm total rainfall should be around half an inch for most.

Once the front blows through Monday morning, winds will shift to the northwest and help usher in a much cooler feel of things. In fact, we expect highs tomorrow afternoon only in the upper 60s for most neighborhoods. Temperatures will then fall quickly into the 40s tomorrow night.

It'll feel like fall tomorrow. — It’ll feel like fall tomorrow.

The majority of the upcoming work week will feel much more like fall, including an extended stretch of lows in the 40s to lower 50s and highs in the 60s. We’ll have to keep a close eye on the late week forecast for rain prospects in association with a cut off upper low. More details on that in the AM. Make it a great evening.

Much Cooler Air On Deck…

Dry, warm close to the work week
Warm weekend
Much cooler air awaits

Summer Feel Gives Way To An Autumn Chill…A backdoor cold front will press into central IN over the weekend and will serve as a focal point for increased clouds at times (northern portions of the state today and more of central IN Saturday). While an isolated to widely scattered shower is possible with this front, most will remain rain-free straight through the weekend. Temperatures will remain well above normal across the region.

A stronger cold front will march towards the area to open the work week. Showers and embedded thunder will accompany the frontal boundary as it pushes through the region. We’ll then note a marked NW wind shift by evening and that will help usher in a true push of fall air. A stretch of mornings with lows in the 40s and highs in the 60s during the day will take us through mid week. Those cooler readings will really being to ignite the color change across central IN.
