3/12 PM All Zones Update: High-Impact Blizzard Likely Tuesday Into Wednesday
Today has been what some may call the “calm before the storm”, as the day has been characterized by mostly sunny conditions across the entire area with temperatures only in the upper 20’s to low 30’s, which is below normal for this time of year. We have also seen some gusty winds across the area thanks to isobaric packing between an Arctic high pressure system centered over the central Canadian prairies and a deep low pressure system off of the eastern Canadian maritime region. As this low pressure continues to the east, winds should gradually diminish this evening as the high pressure from Canada takes control. Tonight should be an excellent night for steep radiational cooling. Under mostly clear skies and light winds, temperatures will be able to fall into the upper single digits for inland locations and teens for the rest of the region, so another very cold night is expected.
