Cold Weather Expected for Saint Louis
Following the passage of a cold front over the area overnight, a surface high is heading into the region this morning. The first northwesterly low and mid-level flow behind the cold front will advect colder air into the area, resulting in temperatures that are several degrees lower today than they were yesterday, even though the sun will be shining brightly under a cloudless sky.
Cold Weather Expected for Saint Louis and the rest of Northeast Missouri
Because of the advent of a dry, seasonal airmass and the presence of a benign zonal flow above, dry and calm weather may be anticipated in the near term. The cold front that passed through last night has brought in a much more normal mid-December airmass, with temperatures in the 20s and even the high teens in some of the coldest locations early this morning.
