More sunshine as High Pressure (“Arch” shape with blue arrows) continues to dry us out and keep us warm. It seems the next frontal system that has any chance to change our weather won’t be seen until Saturday. By Monday the frontal system is well East of us, so it looks like we’ll have a nice day for the 4th of July (actually the whole long weekend).
