WEEKEND WEATHER OUTLOOK
The coming weekend is going to be unseasonably cold and dry. The coastal storm’s track has consistently been forecast to pass south of the Philadelphia area late Sunday into Monday.
[su_note note_color=”#d9f2da”]Despite my winter long range climate forecast for a cold winter in Philadelphia posted last weekend, the latest climate models show the balance of December to be somewhat milder than average. This change is predicted to occur later next week. We’ll see if this happens. [/su_note]
