Be ready to don the sweaters as the coolest air of the season thus far has arrived. This will be quite evident Wednesday morning, as many of us away from the coast could feel temperatures below 40° for the first time since early April. Despite full sunshine, temperatures will only top out in the low 60s in the afternoon.

Thursday will continue to run features well below normal. We’ll once again flirt with 40° in the morning. Temperatures in the afternoon should run a few degrees warmer as cold air advection shuts off and the airmass begins to modify with continued nearly-unfettered sunshine, but we’ll still only top out in the mid-to-upper 60s.

We look to return to the low 70s on Friday as temperatures continue to warm heading into the weekend. Copious sunshine will continue, though perhaps with a few more clouds dotting the skies than in the previous two days. Good weather looks to continue into the weekend, too, with temperatures warming closer to mid-to-late October norms (mid-70s).
