The forecast max for Chicago area today from just 6 hrs ago will be wrong... Just hours before they raised the max temps UP.. lol
Looking at my map above this post looks like its full sun there.

Have bumped up forecast highs some for today, with mid 70s for almost the entire CWA. Still think the daylight hours today will
be dry, but watching the frontal location to our north closely, as
it will lead to an abrupt temperature drop in northeast Illinois
when it heads south at some point this afternoon into early
evening.
A large part of the CWA has been under little to thin cirrus and
upstream conditions would lend that to continue through early-mid
afternoon, though there are signs of mid-cloud development on
recent GOES-16 imagery in northwest/far north central Illinois.
Within the overall upper diffluence, it`s tough to peg where mid
and high clouds may blossom, and that will impact overall
temperatures. Far northern locations right now look like they
could hang a few degrees below elsewhere given the clouds.
South-southwest surface winds have been gusting to 20 to 30 mph across the area this morning, a sign that mixing and advection are ensuing well.The 925mb temperatures at DVN and ILX were both 18C,
about at record levels for late March. While that will cool a
little this afternoon, it`s a sign of the potential aloft. Given
the temperature climb this morning and RAP/HRRR trends, have felt
comfortable inching temperatures up a couple/few degrees. Given
forecast mixing profiles, it would seem like locations east of
I-55 may have potential for gusts to 40 mph.
The stationary front to the north is draped across southern Wisconsin, and lake enhanced southward to just north of the state
line. Pressure tendencies are fairly neutral on both sides of the
front, and with the surface low over the OK/TX panhandles
expected to not move north of east this afternoon, and only
slowly move at that, would expect the lake enhancement of the
front to increase. This should drop southward into northeast
Illinois, and right now lean toward this being a hair earlier than
initially forecast. With this being near peak heating in Lake
County, Illinois, the magnitude of temperature drop could be 20
degrees in 10-15 minutes. Confidence is pretty low on when
precisely this will reach the Chicago lakefront, but presently
have that forecast somewhere between 6-8 pm.
At 9am today they had 72° as the max for today.
At 10am they bumped it to 75°
at 1pm they said 77°
Now at 2pm they said 80° and its still higher! LOLOL
