TRURO: Texas low brings us snow

This weather set-up is fascinating: an arctic high and a Texas Low are playing cat and mouse. The cold high is anchored over Newfoundland and Labrador and on the western edge of that high, there’s an incoming area of low pressure. Cold air is heavy and hard to move so the high will create a blocking pattern- keeping the maximum energy over south-western regions of the mainland. By the end of the day Thursday, snowfall totals should range from 5 to 10 cm. All that clears as the week wraps up but don’t store your shovel away just yet… I’m watching another developing system that will bring more snow late Sunday. This system could serve up as much as 10 cm of new snow followed by a changeover to rain on Monday.
