Wind Advisory: Light Rain Overnight, High 67 Thursday, High 40 Friday

On Wednesday afternoon, Chicago officially passed 53° for the first time since Oct 31, 2018, topping out at 57°F. That marks 132 consecutive days below 54°F, which is the second longest “below 54” streak since records began in 1871.

A deep low pressure system near 970 mb broke some records in Colorado with 80 MPH winds and a blizzard in Denver, and showed a distinct, vast commahead structure this afternoon on satellite and radar images. The system, known as a Bomb Cyclone for its rapidly intensifying low pressure, also includes a severe blizzard in Rapid City, South Dakota.


There is not a lot of rain forecast for Chicagoland with this system, but thunder, and high south-southwest wind gusts are forecast to peak at about 50 MPH about 1:00 to 2:00 p.m. Thursday, March 14, 2019. The highest wind gusts will be in Chicago and southeast to Indiana. Wind gusts won’t be back under 30 MPH until about 1:00 a.m. Friday.

Air pressure is expected to dip to 994 mb from noon to about 3 pm Thursday as the “eye” of the “diminishing bomb cyclone” will be passing to the north through Wisconsin on its trip from southeast Colorado.

Temperatures will begin falling about 3:00 p.m. and fall from 67°F at 1:00 p.m. to 43°F by midnight. Temperatures will stay above freezing overnight Thursday/Friday, but the high Friday will only reach 40°F in the afternoon.
