    Even though under WWA expect maybe 1" of slop far SE McHenry. Maybe 2-3" up on the IL/WI border 

    Depends on where the F-Gen band sets up.

    Wherever it does, there will likely will be a corridor of up to 6", maybe even higher.

    Blocking pattern looks to setup beyond mid month given the ongoing significant SSW and prolonged disruption/decay of the stratospheric PV (perhaps the final warming). Would think moderation of some of the warmth should occur during that period along with a decrease in severe weather chances.

    It most definitely is the demise/final warming of the SPV, no question on that at all.

  3. February 2024 finished as the warmest February on record for Chicago.

    Driest February's
    1. 0.06" - 1877

    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".

  6. 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.

  8. 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.

  9. 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.

  10. 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. 

    I wasn’t talking about the threat, just that they didn’t mention that region.
  11. Posted this in the Chicago record thread, but figured it was worth the cross-post here as well.

  13. The big dog one to watch...

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

  14. 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.

    There’s essentially no chance at a heat index that high, with relatively low dew points expected. (DP’s will be high by Feb standards, but low for getting a 90°+ HI.)
