SAVANNAH, GA (WTOC) - A warming trend sets up across the southeastern United States heading into this weekend ahead of our next cold front, arrival of chilly air.
By Thursday afternoon, many communities will warm above 70°. High temperatures will warm a bit further Friday and Saturday afternoons.
Saturday features unseasonable warmth with high temperatures in the 70s and 80s. Savannah's Saturday average high temperature is 70°. This warmth is occurring ahead of a strong cold front that sweeps through the Coastal Empire and Lowcountry late Saturday or Sunday morning.
A few showers and thundershowers are possible along the front, but rain is forecast to remain brief and relatively isolated.
The biggest local impact? Much cooler temperatures!
Afternoons cool back to the 50s and 60s Sunday through Tuesday of Thanksgiving week.
The big cool-down is due to a reconfiguration of the jet stream across North America, allowing warmer weather to develop across the western United States and much colder air to filter southward, across the eastern United States.
Some data suggests that a generally cool weather pattern will persist through much of Thanksgiving week, with another cold front possible around Thanksgiving Day.
As with any change in the weather pattern, there is some uncertainty. That is especially the case this time as the primary cause of the coming cool-down is still being resolved by weather computer models. If data continues to suggest the same general weather pattern for the next few days, forecast temperatures may be cooled further in future updates.
