The warmest weather since early last October will surge into many areas of the East on Monday, featuring 80-degree temperatures in some locations. The warmup may bring a surge in pollen.
Mild air building in the Eastern states through Saturday will be just a tease compared to the warmth coming Sunday into Monday for many areas east of the Mississippi River.
After flirting with some of the highest temperatures of the season so far over the next few days, the warmth will be quite noticeable by early next week.
The warmth is likely to reach all the way into northern New England and the Maritimes. However, the warm weather will be accompanied by a stiff south to southwesterly breeze.
Only locations with a southern exposure to chilly ocean, sound or bay waters will stay relatively cool.
Forecast High Temperatures Monday, April 14
Despite Monday's warmth, temperatures will stop short of record levels in most areas. For many locations, record highs this time of the year are well into the 80s and lower 90s.
The combination of mild air and recent rainfall helped to bring the cherry blossoms to peak around Washington, D.C., this week.
The surging warmth will allow more lawns to green up, blossoms to emerge and early spring flowers to bloom.
Along with the surging warmth will be an explosion of tree pollen in southern portions of the mid-Atlantic and in parts of the Ohio Valley.
To some extent, the stiff breeze will allow some of the tree pollen to push northward for a time into areas where vegetation is still dormant.
The combination of tree pollen, mold, emerging grasses, old winter brush and other conditions could have some allergy sufferers running for cover.
However, these factors may not necessarily be the source of allergy symptoms for many people.
Despite the upcoming warm surge, this does not mean the end of unseasonable chill for portions of the Midwest and the East.
Another substantial dip in temperatures is in the forecast for much of the North Central states and the Northeast during the middle of next week.
Marking the change from very warm conditions to chilly weather will be a front accompanied with showers, thunderstorms and perhaps even severe weather.
A bit of wet snow is possible at the tail end of the rain at midweek in parts of upstate New York and northern New England.
