Friday Weather Discussion: Colder air has arrived...but for how long?

Good Friday to everyone across the Foothills and Western Piedmont, the weekend is here and we have a big change in the weather pattern.


First off, in the tropics…both Maria and Lee began to accelerate eastward yesterday and is now in the middle of the Atlantic and is going to get incorporated into the mid latitude jet stream this weekend. Good riddance to Maria as its legacy is unfortunately still being written out across parts of the Caribbean.


Back to the local weather, a frontal passage yesterday has ended quite an impressive string of very warm weather. There were widespread 90’s across the Southeast US yesterday which is 10-15 degrees above late September values. Low 90’s prevailed in a few foothill spots and most Western Piedmont locations.


Today will be much different as winds are veering around to the northeast bringing colder air in. Temperatures will struggle to rise as we may see variable cloudiness, most spots will get up into the upper 70’s by late day. With the lower humidity in place it should allow for pleasant weather tonight for your local high school football games. Temps will quickly fall into the 60’s after sunset and into the 50’s by first thing Saturday morning.



A secondary push of cold air will come down through the day on Saturday, that combined with a weak tropical low off the Florida Coastline will result in a solid northeast breeze during the day. This airmass will result in temperatures in the lower 70’s for both Saturday and Sunday afternoons with cool night time values in the upper 40’s (Foothills) to around 50 (Piedmont) on Sunday and Monday mornings.


For our folks in the mountains they’ll see 60’s and low 40’s on these days…that will accelerate the fall colors above 3000 ft.




As we go into the early part of next week, continued northeast flow will keep the weather on the cool side. Daytime temperatures will be in the lower 70’s through Tuesday with periods in which clouds may increase. Night time low’s won’t be as chilly, 50’s for everyone. By mid week the surface flow will begin to veer back around to the southeast meaning warmer conditions for the second half of the week.


Have a great Friday!
