Thursday Morning Update
We have another cold morning, lining up a little better with the Frost and Freeze Alerts. The clearing sky allowed for temps to drop a little lower this morning than yesterday. With more sun today, we should warm back up a little, and continue that trend into the weekend for a pleasant Saturday. Looking to Sunday however, there is a big question mark about a coastal Low trying to develop and bring in showers. I’m watching this for anyone going to the Ravens game.
Morning Surface Weather
That Great Lakes Low is still spinning, now shifting to Eastern Canada. There is still enough energy to pivot clouds across the mountains. There may be a few clusters of clouds at times in the western and northern suburbs.

Freeze Warning and Frost Advisory (in place)
Not much local freezing, but these numbers do match up better with expected widespread frost.

We may have another round of Freeze Warnings and Frost Advisories issued
A warm start on Saturday will bring us sunshine and temps in the upper 60s. I’ve pulled back on the expectation for 70ºF, but a few local spots could get there.
Sunday: The modeling is having a hard time analyzing and developing that Low off the South Carolina coast on Saturday, then moving it north Sunday. The European was most aggressive yesterday, but pulled back. The GFS is still showing rain showers for us on Sunday.
Ravens Game Rain?
I am keeping the risk at 50% for now. So if you are heading to the Ravens Game, prepare for some rain showers and hope it stays east.

CONNECTION TO WINTER?
If you want a snowy winter, this is what you might want to look for in the rest of the tropical season.
