The upper air pattern that brought us all the mild weather for much of this winter season has now reversed. Now the large ridge of high pressure that was responsible for the recent warmth has been replaced by a rather large trough of low pressure for much of the Eastern US. What does this mean to the layman? Well, basically that the cold air that has returned to the region will remain with us for at least another week, maybe longer. Current weather models are hinting at a formidable shot of cold air due to arrive here over the weekend. Should this scenario play out, we could be looking at the coldest temperatures we’ve seen so far this winter season as highs struggle to reach the middle and upper 20’s while lows dip back into the teens. In addition to the cold, we can look forward to lots of clouds, strong northerly winds and snow showers. Stay tuned…
