Rain is arriving. Dew point up to 30F IMBY. Temp dropping. Slim chance of wet snow in SW BC especially around EVI before it transitions to a cold rain.

GFS 16-18 tonight with the defo band

ORD is actually already down into the upper 30s on the 5 minute obs. Front went through there just after 4 pm, which appears to be somewhat earlier than every model that I checked... even the latest HRRR and RAP runs. The 20z RAP didn't have ORD in the upper 30s until 7-8 pm. Will have to keep an eye on the surface temp trends. It's possible this could introduce more of a period of freezing rain later (or sleet if low level cold layer is deep enough).

42F here and it had been a dry day. Just looked out the window and it’s starting to snow lightly. Must be some cold dry air above.

If it was June Phoenix would probably make a run at 130F.
