DAYS 1-5 (DECEMBER 26-30)
The predicted colder pattern is here and will remain here for some time to come. The next winter storm threat is for Saturday, and is too far away to pinpoint any details for, but will be monitored through the week. In the mean time, it will be about the cold and dry weather, with the tiny exception of the slightest risk of a snow shower later today as a few bubbles of moisture from the Great Lakes come along in the westerly air flow delivering the arctic air, which will be in good supply all the way through this forecast period, taking until Friday for its center to migrate from the Upper Plains to the Northeast. Forecast details…
