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…

01.09.21 Weather Bulletin: Unusually Quiet Times Continue…

Updated 01.09.21 @ 8:18a

Fighting For That Sun To Return…Skies cleared overnight across central Indiana and this allowed temperatures to dip into the middle 20s (still about 5° above normal for most). Unfortunately, clouds are once again increasing this morning and will remain with us through the day. We’ll still hold out hope for a few breaks in the cloud cover from time to time through the weekend, but we can expect mostly cloudy conditions to persist.

Looking ahead, there’s really no reason to waste a lot of pixels on the forecast as quiet times remain. Our best opportunity to see more significant sunshine will likely come Tuesday. We’ll then eye a cold front that will pass through central Indiana as we close the work week. Gusty westerly to southwesterly winds can be expected ahead of this front Thursday. This will be a moisture starved system, but we could squeeze out a few scattered snow showers Friday.

Enjoy your Saturday. We’ll be back later this afternoon with a fresh Client Video update.

01.06.21 Weather Bulletin: Watching The Southern Parade Of Storms…

All The Excitement Is South (For Now)…We’ll be “sitting on the sideline” through the upcoming 7-day forecast period as we watch two or three storm systems track through the Deep South. The first of these storms will drop an accumulating snow event for Southern Appalachia Thursday evening and Friday. Meanwhile, we’ll remain quiet back here on the home front with mostly cloudy to cloudy skies. The only other item of note will be an increasingly stiff northeast breeze during this time period (gusts of 10 to 20 MPH).

“Dirty” high pressure will keep our region dry early next week. Despite the extended dry period, we still anticipate dealing with a good deal of cloudiness (hence the labeling). We’ll watch another storm system organize well to our south to open the new work week. Low pressure will move from the northwestern Gulf of Mexico northeast- once again laying down a nice swath of snow for our friends in Southern Appalachia (as well as deeper into the south this next go around).

We still believe things here will start to get busier by the 2nd half of next week…

01.03.21 Weather Bulletin: Snow Ends; Watching Mid – Late Week Next…

Temperatures Trend Colder Late Week…Upper level energy will scoot out of the region as quickly as it arrived and will take the snow with it. Look for snow to diminish from west to east through mid morning. Heaviest bands of the white stuff set up along and north of the I-70 corridor overnight. While the system tracked a tick further north than originally expected, northern portions of our 2”-4” zone should verify once all is said and done (please keep those reports coming). Southern portions (closer to the I-70 corridor) will bust on the low end. Improving weather conditions are dialed up through the 1st half of the new work week, including a return of the sun! (ENJOY)!

Our next system of note will arrive Thursday into early Friday. Operational guidance continues to struggle with handling of features beyond 3 days out (thanks in part to the maturing high latitude blocking pattern) and this feature will require our attention for the chance of a wintry mix of rain/ snow. Stay tuned as we fine tune!

Drier, colder weather is dialed up to head into next weekend. Enjoy the down time while you have it. A fairly active period of weather seems to loom on the horizon for mid and late month…

Thank you again for your patience with posts (along with video troubles) the past few days. We’ll be settled back into the home office Monday and will resume “regularly scheduled” programming at that time.

01.01.21 Weather Bulletin: Prospects Of Accumulating Snow Increasing Tomorrow Night…

Freezing Rain Changes To Rain; Accumulating Snow Tomorrow Night? Low pressure will track into the eastern Great Lakes tonight. Temperatures will slowly rise through the day, allowing freezing rain to transition to rain. Slick roads this morning will slowly improve through the afternoon.

Attention will then shift to a trailing piece of upper level energy Saturday night and Sunday morning. While thermal profiles are marginal at best, the track and strength of the upper level energy will lead to the potential of accumulating wet snow Saturday night and Sunday morning. These are the kind of systems that can manufacture their own cold and result in “surprise” snow events for some. As things stand now, we expect a band of accumulating snow to develop across central Indiana into western Ohio tomorrow night and Sunday morning. We’ll keep a close eye on data the rest of the day and update later this evening.

Weak high pressure will nose into the region as we kick off the new work week, allowing sunshine to return.

12.30.20 Weather Bulletin: Timing Out Period Of Wet Snow By Evening; Icy Glaze To Open New Year’s Day…

Rain Ends As Wet Snow This Evening…A cold rain will continue to overspread central Indiana this morning. A cold front will slip south across the state through the afternoon and temperatures will fall into the 30s prior to sunset across most of the region. One final wave of moisture will push northeast across the area as temperatures fall into the low and mid 30s leading to a brief period of wet snow between 6p and 10p (northeast to southwest). We’re likely only looking at a window of 1-2 hours of snow at any one location, but it could fall moderate to heavy during that brief window and accumulate between a dusting and 1.5″. We’ll keep an eye on model trends through the day.

New Year’s Eve will feature dry, but gloomy and cold conditions. Look for overcast skies and highs struggling to make it to freezing.

Our second area of low pressure will lift north from the northwestern Gulf Coast into the Midwest Friday and Saturday. This will help widespread precipitation overspread the Hoosier state New Year’s Day (before sunrise for most). With cold air locked in at the surface, precipitation at the onset, continuing for a few hours north of a line from Terre Haute, Bloomington, and Cincinnati, will fall as freezing rain. If traveling early, we’d recommend caution as a light icy glaze (less than .10″ for most) is a good bet. Eventually warmer air will win out, switching things to a “plain ole rain” late morning into the afternoon.

Lingering showers will end Saturday as a trailing piece of upper level energy moves east across the Ohio Valley. Dry skies will return as we open up the new work week.

VIDEO: Strong Arctic Front Crosses The State Tonight; Looking Ahead To A Busy Close To 2020…

The day is dawning with quiet conditions, but that all begins to change in significant fashion by evening. During the transition, strong and gusty winds (SW 45-50 MPH gusts) will…
