Wind
and mid to high-level clouds meant that it only dropped to 72F last
night! It might get lower than that by 06z tonight though. It cleared
out somewhat by late morning and rose to 84F before thicker mid-level
clouds came in. Max wind is 19 kt.
Today’s forecast will be the trickiest of the week so far. Showers and
possibly a thunderstorm ahead of a cold front tonight will bring some
rain, with models differing on how much. Most likely, the heaviest will
be to the southeast, with relatively light amounts at KORD. The front
will only slowly push east, and a solid deck of high clouds lingering
behind the front will initially prevent it from warming up much during
the day tomorrow. However, clearing late in the afternoon will lead to
more of a warmup then, with the high perhaps not achieved until 21-22z.
It will be much cooler than today with the cooler air behind the cold
front, though it will still be warmer than average since the air mass is
not that cool yet! Mostly clear skies (except a few mid-level clouds)
by tomorrow night and cool advection will lead to the low being at the
end (Friday 06z), but with winds being just strong enough to prevent
strong radiational cooling (i.e. probably still near or a bit warmer
than most models). Note that the HRRR surface inversion at the end is
likely not really going to happen given the wind. Overall though, winds
will be weaker than today and will be out of the west, offshore, so no
influence from Lake Michigan is expected.
