BOX not really impressed with the temps next week at this point... cold but nothing outrageous.
Appears that high pressure builds back in on Wednesday and there
could potentially be arctic air over the region, but there is a lot
of spread between the operational guidance in 850 hPa cold air
moving in. The CMC is currently the quickest bringing the arctic air
in for Wednesday, but the ECMWF/GFS/GFSv16 and ICON don`t push the
coldest air in until late week. Still sticking with the NBM guidance
given the differences. This features highs in the 20s to 30s for
Wednesday.
