02.01.21 Weather Bulletin: The Arctic Hounds Come Calling…

Updated 02.01.21 @ 6:34p

Bottom Drops Out Early Next Week…Brief high pressure will build overhead through the next 24 to 48 hours and supply a return of sunshine. We may still have a few light flurries around through the early afternoon Tuesday, but the story over the next couple of days will be improving weather, albeit still chilly.

Our next storm system will approach Wednesday night and Thursday in the form of a cold front. Precipitation should arrive Thursday morning as a cold rain (might start as a brief wintry mix, but this shouldn’t be a big deal). The cold front will then sweep through the state Friday morning. Highs will likely take place during the predawn hours with falling temperatures through the day. Any lingering morning precipitation should exit stage right relatively quickly.

Things become much more interesting over the weekend as a couple of arctic fronts sweep across the region. The first front will feature vigorous upper level energy and will likely result in a period of snow. The second front will really drop the “arctic hammer” and not only lead to the coldest air we’ve seen in quite some time, but a continuation of snow chances into early next week.

We’ll keep a close eye on the development of things for the weekend. With arctic air getting involved, it’ll likely maximize any available moisture and a couple of seemingly rather “harmless” snow events could turn into over-achievers as we grow closer. I’d keep close tabs on the weekend forecast.

Bitter air will pour into the region early next week, including dangerously cold wind chill values. Those with ag/ livestock interests should be prepared to make adjustments for the severe cold.

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.
