SAVANNAH, GA (WTOC) - Cold air is building across Alaska and northwestern Canada. Some of the frigid weather is being funneled in from Siberia.
The weather pattern across North America will temporarily keep this winter chill bottled up well north of the "Lower 48". This holding pattern changes gradually over the next week. A large trough of low pressure – or dip in the jet stream – will allow cold air to spill into the northwestern United States on Monday.
By mid-week, the strong cold front will be sweeping into the central and southern plains, arriving in our region as early as Wednesday.
As the front pushes through the Coastal Empire and Lowcountry, isolated showers and gusty winds are possible. Winds may gust greater than 30 MPH as the temperatures tumble. However, the bigger story is what is expected well behind the cold front.
The coldest temperatures since last winter and threat of a widespread inland freeze are expected by next Friday and Saturday; Dec. 9-10. A hard freeze cannot be ruled out in localized areas by Dec. 10.
If you have not winterized your home, please do so this week. The First Alert Weather Team will continue to track this cold front and any impact it may bring to our region.
