01.22.21 Weather Bulletin: Cold Weekend; Messy Open To The New Week Ahead…

Updated 01.22.21 @ 9:20a

Focus Is On Next Week…The 1st half of the weekend is easy as high pressure builds into the area, supplying a fresh batch of cold, dry air. Enjoy the sun while you’ve got it. (Don’t anticipate much in the vitamin D department next week). Saturday morning will be very cold (middle 10s for most with single digit ‘chills).

Clouds will thicken up Saturday PM and an initial wave of moisture will arrive into central Indiana Sunday morning. This lead wave of precipitation should be on the light side but with cold air in place, it’ll likely fall as a wintry mix of sleet and potentially freezing rain across the southern half of the state. Where the cold air is a little deeper further north, the predominant precipitation type should take on the form of light snow Sunday morning.

After a potential “lull” Sunday evening, another slug of moisture is inbound Sunday night and Monday. As surface low pressure tracks along the Ohio River during this time frame, this round of precipitation will be heavier and more organized. While this will still require fine tuning, our initial thinking is the form of precipitation will likely fall as the frozen variety across the northern 1/3 of the state with more mixing across immediate central Indiana, and predominantly liquid downstate. We’ll keep a very close eye on the data throughout the weekend, but our initial idea can be found below. Where the precipitation type is predominantly snow, this should be a “plowable” event. Stay tuned.

We’ll have to track another feature by the middle of next week. This could, too, deposit additional wintry conditions across the region, but we need to get through the lead system before trying to get too cute with the mid week feature.

01.18.21 Weather Bulletin: Weak Upper Level Disturbances; Bigger Storm System Late Weekend…

Updated: 01.18.21 @ 8:45a

Parade Of Upper Level Disturbances…In what’s been a seemingly unending round of upper level disturbances, we still have 2 more to deal with before we can welcome in high pressure to allow a brief window of quieter weather by late week.

After a mostly cloudy day with a few flurries, a more organized band of snow will roll into south-central Indiana after dark (towards 9p-10p across western areas before overspreading the rest of south-central Indiana) and could deposit a quick inch of snow during the overnight for our friends in Bloomington, Nashville, Seymour, and Columbus. The snow will depart about as quickly as it arrives and will be “outta here” before sunrise Tuesday.

One last upper level feature will race through the state Tuesday evening and early Wednesday with yet another round of scattered snow showers (dusting level stuff).

We’ll then welcome in a cold front Thursday evening and early Friday morning (one of those days where the high will likely come at midnight). The frontal passage will be a dry one, but we’ll notice an uptick in gusty northerly winds during the day Friday. High pressure will then center itself over the Ohio Valley Saturday with a return of sunshine. It’ll be cold though!

A more organized storm will lift northeast into the Ohio Valley by the 2nd half of the weekend. From this distance it appears as if it’ll be one of those “wintry mix to rain” scenarios. More on this and the overall pattern to close the month later today in our Client video update!

01.15.21 Weather Bulletin: Periods Of Snow Into Early Next Week…

Updated 01.15.21 @ 7:58a

Snowy Periods Into Early Next Week…A big ole upper level low pressure system will swirl across the Ohio Valley and into the Northeast through the weekend. Individual spokes of energy will “pinwheel” through central Indiana between now and early next week. These will be efficient snow producers at times through the period. While we’re not looking at a widespread heavy snow, the persistent and rather long duration of this set-up will have most central Indiana neighborhoods accumulating between 1″ and 3″ by Monday morning. We still anticipate localized intense snow squalls to hit this afternoon and evening. If traveling during that period, please allow yourself extra time to reach your destination. We’ll have to keep close tabs on additional light snow accumulation chances Monday night into Tuesday morning as a final piece of upper level energy scoots through the state.

As for temperatures, we’ve already seen our high for the day. Temperatures will slowly fall to around freezing just after sunset. We’ll see little movement on the thermometer into the middle part of next week.

A bigger storm system looms late next week, but there are many more questions than answers right now regarding the track of this low pressure system. That picture will become clearer over the weekend.

More on all of this later today in our Client video update. Make it a phenomenal Friday!

01.14.21 Weather Bulletin: Wintry Conditions Return For The Weekend…

Updated: 01.14.21 @ 7:47a

One More Relatively Mild Day…A southwesterly air flow will combine with just enough early sun to help boost temperatures into the 40s for one more day. Enjoy as colder air arrives to close the week!

A cold front will pass through the state tonight. A broken band of showers will accompany the frontal passage later this evening. Light will be the key word (0.10″ or less). As colder air filters into central Indiana, scattered snow showers will develop by Friday morning.

Things begin to turn more interesting Friday afternoon as the upper level low pressure system drops south and individual spokes of energy ride into central Indiana. As this takes place, the combination of very cold air aloft and just enough instability (byproduct of daytime heating- yes even this time of year) will warrant conditions that should help heavier and more intense snow bursts (or squalls) develop. While we’re not talking about widespread heavy snow accumulation, these squalls will be intense enough to impact travel throughout the region when encountered. Please plan accordingly and give yourself extra drive time tomorrow afternoon/ evening if you have travel plans. Once the sun sets, the snow squall activity will quickly diminish in coverage and intensity.

Additional periods of light snow can be expected throughout the weekend as individual upper level disturbances cross through the area. At this time, Sunday appears to offer up the best chance of more widespread, organized light snow. We’ll also need to keep an eye to our northwest for one more trailing feature Monday PM into Tuesday (the “caboose,” if you will, in the seemingly unending weekend train of upper level disturbances).

By the middle part of next week, we’ll be able to catch our breath and await the potential of a bigger, moisture-laden storm system impacting the area late next week…

Make it a great Thursday! We’ll be back later this evening with an updated video discussion focused on the long range…
