Lead Forecaster Daniel Crawley
What an incredible Saturday we had across the Western Carolinas. A nice trough settled in across the Northeast US and pushed a nice pleasant change to what has been a summer full of heat and high humidity. We experienced a mix of sun and clouds today with high temperatures in the lower 80’s, however the big story was the lack of humidity. Dewpoint temperatures were firmly in the 50’s and there were even some upper 40 degree dewpoints across the Triad Region.
Looking at what is happening at the upper levels of the atmosphere we have the northeast trough and a tall ridge across the Plains and Rockies. A conveyor belt of shortwaves will start to dive southeast and that over the next 24-36 hours will begin to provide subtle changes here across Western North Carolina. The first piece of energy is located across Northern Minnesota.
Sunday will be another nice weather day across the Carolinas, with the less humid firmly in place don’t be surprised to see a few upper 50’s dotting the landscape early Sunday morning.
By that point the winds in the lower levels of the atmosphere will veer to southeast. Once we get to Sunday night, the shortwave energy across Minnesota will morph into an upper low. That will start to transport moisture back into the region especially Sunday night. The daytime tomorrow will continue to be pleasant but expect a slow return to humid conditions by first thing Monday morning.
Showers and a scattered storm returns to the forecast on Monday as the upper level feature brings a jet streak across the Tennessee Valley and into the Carolinas. That will provide a good lifting mechanism.
