..A cold front will bring showers and thunderstorms to the
Southeast and Florida through the weekend...
..Increasing rain chances expected in northern California and the
Central Great Basin to start the new work week...
..Cool conditions set to continue in the East, while the West
sees unseasonably warm temperatures...
A cold front situated over the Gulf and northern Florida will
continue to bring showers and thunderstorms to the region today. A
combination of a robust low-level jet, an inflow of comparatively
warm, moist air from the Gulf, and the presence of the front will
aid in fueling rounds of thunderstorms throughout the day.
Thunderstorms will have the potential to be severe, bringing a
risk of damaging winds, isolated hail, and the possibility of a
tornado or two. As a result, there is a Slight Risk (level 2/5) of
severe thunderstorms for Saturday, per the Storm Prediction
Center’s Convective Outlook. Meanwhile, a secondary cold front
will move through the Mid-Atlantic and Northeast through early
Sunday morning. This will bring rainfall to portions of the
Northeast, with the possibility of a wintry mix in northern
Vermont, New Hampshire, and Maine. Afterward, a coastal
low-pressure system is forecast to move northeastward along the
Gulf Stream. While the system is expected to remain offshore, it
will sustain showers and isolated wintry precipitation across New
England to end the weekend.
In California and the Central Great Basin, a slow-moving frontal
boundary will progress through the region throughout the weekend
and into early next week. An upper-level trough off the California
coast is forecast to evolve into a cut-off low and remain in place
as it becomes disconnected from the main jet stream. Early next
week, the trough will eject inland over northern California,
allowing the surface frontal boundary to gain momentum and move
eastward. This will result in increasing precipitation chances for
California and parts of the Central Great Basin. Simultaneously, a
separate frontal system in the Northern Plains and Rockies will
bring a return of precipitation to start the work week, followed
by cooler conditions.
In the eastern half of the country, cooler-than-average
temperatures are expected to continue through the remainder of the
weekend. In the Southeast, temperatures are anticipated to stay in
the low to mid-60s, while the Great Lakes region could see highs
dip into the upper 40s today. Additionally, reinforcing surges of
cool air behind the departing fronts will lead to chilly nighttime
temperatures, with the potential for frost/freeze concerns for
portions of the Ohio Valley and Central Appalachians through
Sunday morning. Meanwhile, in the Northwest, temperatures will
remain well above average. Parts of Washington and Oregon could
see highs approaching and potentially exceeding 90 degrees on
Sunday. A cooldown is then set to begin for most of the West as
the aforementioned frontal systems move through, with the
exception of the Pacific Northwest, which will remain unseasonably
warm through early next week.
