With the snow at ORD last Friday evening and the t'storms last evening at ORD, the pursuit of a top 10 driest February has ended. The monthly precip total for February 2024 is now up to 0.63".

Chicago/O'Hare had a high temperature of 71° on February 26th, which broke the record high max temperature for the date of 64°, which was set in 2000.

Chicago/O'Hare had a low temperature of 52° on February 27th, which broke the record high min temperature for the date of 42°, which was set in 1896.

All-time and daily record temperatures in jeopardy the next few days...

•Winter all-time record max temp - 75° (2/27/1976)

•February all-time record max temp - 75° (2/27/1976)
•February all-time record min temp - 54° (2/8/1925)

•Monday, Feb 26th Max Temp - 64° (2000)
•Tuesday, Feb 27th Max Temp - 75° (1976)
•Tuesday, Feb 27th Min Temp - 42° (1896)

Broke the record high max temp on Feb 26th and the record high min temp on Feb 27th.

However, just barely missed the record high max temp on Feb 27th, the all-time record Feb high max temp, and the all-time record winter high max temp with a high of "only" 74° at ORD yesterday. Also, just missed the all-time record Feb high min temp with a low of "only" 52° at ORD yesterday.

it's been over.

if OHweather or myself are not posting tl:dr posts about the long range, there's nothing to see for you winter loving people.

The line of severe t'storms that swept through the metro ended up producing a peak wind gust of 41MPH and 0.50" hail at ORD.

It wasn't anything too exciting, but solid for February. The lightning/thunder production may have been the best I can remember in February.

Anyone else notice the super sharp dryline forming over Missouri and Illinois?  I don't think I've ever seen a dryline like that so far north and east.

That's part of why there is a risk today.

74° at ORD currently.

Just shy of all of the records in play...

Wish I were able to be chasing today, but couldn't swing it at work.

There two targets overall that I would have considered...

•N Illinois near the SLP/CF/DL/WF intersection. However, it's unknown if this activity will be surface based or not.
•I-80/southern Chicago suburbs down into E IL/IN. Dryline play for discrete supercells, should the cap erode.

Typically this time of year the lakes keep warm frontal boundaries from surging northward past the MI/IN/OH borders, but this year the water temps are well above average and no ice - albeit still cold enough to create a stable boundary layer, just not as profound. They’re probably thinking that the warm frontal surge along with cooler waters will slow the forward propagation of the aforementioned surge while keeping the threat suppressed further south… but for interior regions of southern Michigan, especially away from the lake, I would beg to differ. 
 
Pretty conditional still, but may be in for a surprise.

lol the SPC basically ignored Michigan in the text

They tend to do that at times, and there's no real rhyme or reason as to why.

I didn’t realize the scale of the streak in the 1870s and 1880s. Is measurement error a possible blame there?

It's more-so that the observation location was either by the lake or downtown.

Posted this in the Chicago record thread, but figured it was worth the cross-post here as well.

The big dog one to watch...

No chance at the warmest winter on record, but getting into the top 5 is certainly possible.

Warmest Winter’s
1. 37.2° - 1877/88
2. 35.7° - 1931/32
3. 35.2° - 1879/80
4. 35.1° - 1881/82
5. 34.6° - 1889/90
6. 34.4° - 2023/24 (Thru 2/24)
7. 33.6° - 1875/76
8. 33.2° - 1997/98
9. 33.1° - 1918/19
10. 32.8° - 2011/12
10. 32.8° - 1920/21

Just saw in today's St. Louis Post Dispatch that Fox 2 in STL is predicting 80 degrees for high in the St. Louis area on Tuesday.
I am going to go on a limb and predict that at least one point in the immediate St. Louis area will not only surpass 80 on Tuesday, but have at least a 90 degree heat index for a time as well.  On Feb. 27.

Picked up a T here and at MLI/DVN.  Not sure what the records are for least snowy February but MLI will probably be in the top 5 with their 0.6" lol.

Several things to watch as we head towards the conclusion of February...

A tie for the least snowiest February is in serious jeopardy this evening/tonight.

Luckily, I'm working... 

And just like that... We are not only out of the running for least snowy February on record, but we are out of the running for top 5 least snowy as well.

we should still get warmest or near there I imagine 

Running the numbers just roughly off of the NWS forecast (Likely underdone a bit early next week), we are in the running for the top 5 warmest, but not close to 1st.

We would need temps to overperform their current forecast by quite a bit to make a run at the record warmest.

A tie for the least snowiest February is in serious jeopardy this evening/tonight.
