Detailed Discussion
St. Patrick’s Day seemed to infused with a bit of mischief – as though a leprechaun snuck into the weather factory. The Sun burst forth, only to be interrupted by passing showers, even some wet snow across the higher elevations. Temperatures ranged from the 30s in the mountains, nudging 50 degrees in the warmer, sunnier valleys. Rather than a magical being, it would be the passage of a cold front, interacting with the mountains and the strengthening sun to create localized and changeable conditions. This is a typical scenario as we head into Spring, waiting in the wings for its calendar arrival late tomorrow evening at 11:06 daylight time.
Yesterday’s changeable, somewhat chaotic character, gives you some insight to the expected conditions today. Although the scattered showers and snow showers tapered off overnight, another pulse of energy and a push of colder air from Ontario and Quebec will trigger additional passing rain or wet snow showers, especially over the higher terrain north. The activity is expected to increase this afternoon and expand a bit south, primarily over the mountains. Blustery northwest winds will limit temperatures to the 30s and low 40s north, and low to mid 40s south. Once again, the activity diminishes overnight, while the colder air continues to arrive, so that Spring’s arrival will be far colder than most of the last few weeks of winter. Just a few flurries should linger over the mountains tomorrow, while periods of sun develop in the northern valleys, and most of the south. Blustery northwest winds will further the cooling trend, temperatures mostly in the 30s north, and either side of 40 south. By Wednesday, another installment of colder air forces additional clouds and snow showers to work through the region, mixed with some rain showers in the valleys. Even colder air follows for the end of the week, along with generous amounts of clouds and a few stray snow showers for the northern mountains.
