Central PA Summer 2020: Hoping The Heat Makes a Hasty Retreat in Upstate New York/Pennsylvania Posted August 14 4 hours ago, Bubbler86 said: SO what is the meaning of areal precip? I know most of the LSV is below normal for the last 60 days so it cannot mean actual precip. Here if you take Mid June to Mid August we are about 4" below "average" The areal precip would be each county-wide average that is likely derived from their products/maps that estimate precip. So while the overall average on a county is a certain number, there can be portions of that county that actually saw less or more than that number. Centre county has been well, dead center in the driest conditions all summer so definitely no surprise that county is running significantly below average. In this county (Blair) I can pretty much assure you I've seen nowhere near the 3.7" of precip in the last 60 days in my neighborhood.
