Friday: Expect a partly cloudy sky today with lower humidity than previous days thanks to a wind change behind the weak system which has moved east of us. the lower humidity/slightly drier air will lead to more sunshine during the afternoon and less clouds or storm chances. We'll mention a slim chance for a late day storm, but the chances of one popping in your town are very low. Highs will reach the low 80s in the Upstate with middle-upper 70s in Western NC.
Saturday: Similar to Friday, Saturday will be a great day! You'll be able to enjoy plenty of sun with highs in the low 80s for Upstate towns and upper 70s for Western NC communities. If you are headed out to the Greek Festival or any other local events, don't expect rain to ruin your plans!
Sunday: Humidity will begin to build back on Sunday and so too will a few more afternoon clouds. Still, we'll enjoy a nice day with some sunshine mixed in as well. We have to include some isolated storms back into the forecast for Sunday, although it looks like there will be a better chance for scattered clusters of rain and storms on Monday and Tuesday of next week.
Worth Another Mention: Since it was tucked so far down on my post from yesterday, I wanted to mention the lack of any sort of heat wave in May. After looking back through our recent climate records from over at GSP Airport, the highest temperature recorded at GSP so far this spring was on April 2nd at 88°. That's right... we have yet to reach higher than that since and we still haven't hit 90° at GSP for May (yet at least). This is surprising considering the kind of heat we are used to around here in May!
Also, the average high temperature so far this month (through the first 16 days of May) at GSP is 79.93°. It doesn't look like the next seven days will offer any 90°+ sort of heat... in fact, we may not get above 85° on any afternoon.
