01.27.21 Weather Bulletin: Snow Builds In This Afternoon For The Southern Half Of The State; Keeping Close Eyes On The Weekend…

Updated 01.27.21 @ 7:51a

No Rest For The Weary…A fast moving area of low pressure will scoot east this afternoon and evening. This will spread a swath of light to moderate snow across the southern half of the state in the 1p (west) to midnight (exiting southeastern portions of the state) window. While still primarily a light event, models have “beefed up” snow amounts ever so slightly with this system over the past 24 hours. Our snowfall forecast for system #1 can be found below.

Colder air will pour in for all during the overnight and should be just enough to kick up some lake-generated scattered snow shower activity into Thursday morning.

Weak high pressure will then build in and supply a sunny close to the work week. You enjoy the sun and briefly quieter weather and let us worry about the weekend!

Speaking of the weekend, this is the period that continues to look increasingly likely to produce the most impactful winter storm of the season for our immediate area. We forecast early sun to quickly give way to a lowering and thickening cloud canopy Saturday (the sky will have the looks of a snow storm brewing by lunch for most). Precipitation will then overspread the region from southwest to northeast as we progress through the afternoon. The potential is there for a heavy wet snow thump Saturday PM before precipitation transitions to a wintry mix as low pressure scoot by just to our south. Before that transition, “several” inches of wet snow is looking increasingly likely. As colder air wraps back around into the region, wrap-around moisture will fall as light snow and snow showers into early next week.

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!
