Arctic Blast headed to the Southern Interior…
A major change in the weather pattern will occur this Sunday. The change will take place in two steps – the arrival of a Pacific front followed by an Arctic front. On Sunday a Pacific front will sweep across the Southern Interior. The snow level will fall rapidly with this system. Rain at lower elevations ahead of the front will quickly transition to snow as the front passes through and temperatures drop.
A blast of very cold Arctic air will push south through the Central Interior Sunday night. Snow, blowing snow with near zero visibility and rapidly falling temperatures will mark the arrival of the Arctic front. Local snow accumulations are likely. The front will move through the Southern Interior Monday afternoon. By Tuesday afternoon the winds will ease to moderate and there may be only a few flurries lingering along the US border. By Wednesday sunny but chilly weather will prevail in the stubborn Arctic airmass that will persist through the end of the week.
