Chicago Storm

It never really looked all that cool, more seasonable to even a bit above. .

Peak of 80 here at ORD thus far today. Edit: 81 for a high.

A high of 76° on 3/26/1989 is the warmest Easter prior to April 10th on record. Tomorrow could get close. .

March 2021 was tied 10th warmest March on record for Chicago... Top 10 warmest March's 1. 53.5° - 2012 2. 48.6° - 1945 2. 48.6° - 1910 4. 47.2° - 1946 5. 45.8° - 1921 6. 45.3° - 1878 6. 45.1° - 1973 8. 45.1° - 1938 9. 44.7° - 1977 10. 44.2° - 2021 10. 44.2° - 2000

RH made it down to 16% for a time today at ORD...Which was only a few % off the record min.

first need an actual lockdown for that. .

That’s really not the case... There is no significant forcing via teleconnections, until maybe we get into mid April. Definitely could get into a stagnant pattern for a bit. .

Overdone for that timeframe. .

that’s not the same thing overall.

Sat-Mon are the only locked mild/warm days. After that there is a lot of question. That once wall to wall warm late March into mid April idea is a distant memory. .

Kudos to the RGEM/GEM, which were generally weaker/east most runs leading into today. .

Guidance did terribly with this storm system, which obviously had an affect on the severe t'storm risk for a large area...and will have an affect on the wind/rain aspects for many areas as well. As others mentioned above, the Euro was particularly bad... The 0z run had a 981MB SLP in NW IN tonight, while the new 18z run has a 992mb SLP in NW OH.

Activity to the south finally starting to interact with it a bit.

It went right over the Bibb County correctional facility.

Catch-all severe and wind thread...
