A pattern shift is coming, but first, cold weather tonight in #StLouis & nearby areas. A warming trend takes place through the weekend. We stay mild into next week in the Midwest. In fact, forecast data points to a big time warm-up for much of the U.S. Most of the model ensembles show above normal temps, as illustrated below on the ECMWF Ensemble 850mb plots. The first temp map is for this Friday morning, the next map is for the following Friday (Dec 12th) morning. Orange color indicated mild air aloft, blue is colder air aloft, meaning we see warmer than normal conditions at the surface. Bottom line, December will start off mostly warm.
