The calendar says January, but we’re feeling more like April in the Mid-Atlantic and Southeast with temperatures reaching as much as 30 degrees above average this Friday. What a nice way to end the week!

Washington D.C. has officially set its all-time record high temperature for January. Dulles International Airport reached 79F this afternoon and Reagan Airport got to 80F.

Back in 1950, D.C. set their first all-time record high of 79F and today's 30-degree above-average temperature knocks that down to second place. A week ago, between 3 and 5 inches of snow covered the ground, and temperatures earlier this week got to the single digits.

If you look back to last week’s temperatures and weather conditions, a deep freeze had taken over much of the eastern half of the U.S., and a snowstorm was happening across the Ohio Valley, Mid-Atlantic, and Northeast. It only took 7 days for the calendar to completely flip and give us a spring preview!

Thanks to strong southwesterly flow, temperatures will be reaching the 60s and 70s on Friday from southern Pennsylvania through the Southeast. Florida will be enjoying a mix of 70s and 80s.

A high-pressure ridge is exiting into the Atlantic, and its clockwise flow is pulling up abundant warmth out of the south and Gulf of Mexico. This warmth is about to break high-temperature records from Baltimore to western South Carolina.

These will be some of the warmest temperatures felt in late January since the 1940s and 1950s.

That’s not all. Nighttime temperatures will stay much above average for many across the Upper Great Lakes through the Mid-Atlantic and down to the Sunshine State.

It may not sound so warm but a place like Hibbing, Minn., usually has lows near 0F this time of year. Saturday morning’s forecast low temperatures will come close to the 2015 warm record of 25F with a forecast of 24F.

Further south, Tallahassee, Fla., has a forecast low of 62F, which could tie the record warm low of 62F set back in 1974.

These warmer mornings last through Sunday before we swing back to more average or slightly above-average temperatures across the East as a low-pressure trough digs in.

The storm system bringing heavy rain and thunderstorms across the Deep South on Saturday will shift east bringing heavy downpours and even some higher elevation and Northeast snow. Weather whiplash after Friday’s spring preview.

If you’ve got weekend plans, be sure to keep a close eye on the WeatherRadar. And remember, there are less than 55 days until the spring equinox!
