Dinnertime Rambles: Active Night And Sharply Colder Wednesday…

Updated 02.27.24 @ 6:42p

As we write this update, severe storms are firing across northern IL where a Tornado Watch has been issued until 11p (eastern). Meanwhile, all is quiet on the home front, thanks to strong “capping” in the mid levels of the atmosphere. Unfortunately, that cap likely won’t hold and we still anticipate scattered strong to severe storms to impact central and southern Indiana during the overnight.

All modes of severe weather remain on the table, including damaging straight line winds, large hail, and tornadoes. Initiation of convection across central/ southern IN should come around or just after midnight and end by 3a to 4a (west to east).

Please make sure you have a means to receive the latest severe weather alerts prior to heading to bed tonight.

By the time most are waking up Wednesday, we’ll be talking about an entirely different array of conditions. Sharply colder air, light snow showers, and strong northwesterly winds will ensure to remind folks it’s late-February, after all.

Monday Evening Thoughts On Storm Potential Tonight – Wednesday…

Updated 02.26.24 @ 5:51p

The Storm Prediction Center (SPC) has expanded the ‘marginal’ risk area within their Day 1 Outlook. This is for the potential of isolated strong cells developing later this evening and through the overnight (large hail being the biggest concern from any stronger cell that pops), but this shouldn’t be a widespread severe weather event by any stretch of the imagination.

The Day 2 Outlook remains largely unchanged from this morning across our immediate area.

Concern remains that all modes of severe weather will be realized across northern IL and northern IN Tuesday evening into the overnight.

We want to reiterate that the majority of the daytime should be void of any sort of significant rain or storms across the state. It’s after 7p, and more so after 9p, that we expect discrete cells to initialize and roll across northern IN. These discrete cells will be capable of rotating (TOR potential remains), but also have the potential of damaging winds and large hail. The most widespread of evening convection should be focused north of the city, itself, but we’ll keep a close eye on tonight’s and Tuesday morning’s data.

We continue to believe a more pronounced squall line will march east across the state, including central and southern Indiana, during the overnight and predawn hours and it’s with this line that an elevated damaging wind threat will be hoisted. Timing this threat out features the 2a to 5a Wednesday time block from west to east. We recommend reviewing your severe weather safety plan and have a means of receiving the latest warning information should they be issued.

Showers and embedded thunder will remain widespread through the early morning hours before pushing off to our east by mid morning. By this time, we’ll be trending sharply colder (temperatures will fall off the cliff Wednesday morning), drier, but very windy.

Predawn highs around 60° Wednesday will be shaved by 30° by late morning along with a biting northwesterly wind gusting 30-40 MPH.

High pressure will deliver a colder, but sunny Thursday before a weak system delivers a return of clouds and light (insignificant) showers to close the work week.

The weekend continues to look mighty nice, including a quick rebound in the mercury and another taste of spring ahead of our next approaching storm early next week.

Weekly #AGwx And #Severe Weather Outlook…

Updated 02.25.24 @ 7:55a

Though a bit earlier than usual this year, it’s time to “dust off” our dedicated weekly post aimed solely at looking at the potential of severe weather in the week ahead. You can expect this to be posted each Sunday morning moving forward through the spring and summer before sunsetting for another year come late September.

An anomalous pattern will dominate the period as we close February and open March. The eastern ridge will become stronger in response to a digging trough across the Western CONUS.
Well above average temperatures can be expected for the Plains and Eastern CONUS through the upcoming week. Cooling behind our midweek frontal passage will be brief before another significant warm-up late week.
The upcoming 2-week period should yield above average precipitation to the majority of the forecast area (to well above average across the Southeast).

Forecast period: 02.25.24 through 03.03.24

The “headliner” system in the forecast period is an area of low pressure tracking into the Great Lakes region Tuesday into Wednesday (02.27 and 02.28). This will drag a trailing cold front through the Ohio Valley Wednesday morning into the afternoon (west to east).

The Storm Prediction Center includes most of the region in some sort of risk of severe weather Tuesday. The greatest risk of severe appears to include an area north and west of a rough line from Evansville northeast to Bloomington and Toledo, OH. While all modes of severe weather are in play, we remain most concerned for the threat of damaging straight line winds Tuesday PM.

Ingredients aren’t off the charts (rarely are this time of year), but parameters are sufficient enough to warrant the chance of strong to severe storms Tuesday into very early Wednesday morning before the cold front moves through the region and results in falling temperatures and a much more stable airmass engulfing the entire OHV through the day. Stay tuned as we continue to fine tune specific timing of storms.

Beyond this point, an area of high pressure will settle overhead, resulting in a much more stable pattern to close the week and head through the weekend. Expect sunshine to return and another quick warm-up to get underway during this period. Highs will zoom back into the 60s next weekend.

Looking ahead, we’ll need to monitor the threat of another potential strong-severe storm window during the early to middle stages of next week. Far too early for specifics, but similar ingredients appear in play which isn’t shocking given the ‘mean’ upper air pattern shown to open this post. We also want to reiterate the above to well above average precipitation expected throughout meteorological spring. Image 3 above highlights the wet look over the upcoming couple weeks.

Upcoming Storm Dates to keep an eye on:

  • 02.26 – 02.27
  • 03.03 – 03.05

*10-day rainfall projection: 1.25″ – 2.25″
