Valley highs will warm to the low 80s this afternoon, likely the warmest day of 2014 so far.  

High pressure will continue to build into the NorthState this week.  That will generally keep the skies blue and the temperatures warm.  Both Monday and Tuesday will keep highs in the low 80s (about 15° above average) and sunshine abundant.  That high pressure area will move to our east by Wednesday and will open up the door for a weak cutoff low.

That low won’t have much of a connection to the surface, and will therefore just create some sprinkles at the highest elevations, and mostly to our south.  What the cutoff will do is bring some mid and high level clouds overhead.  Those clouds will keep temperatures cooler, but not cool by any standards – expect the coolest temps this week to remain in the upper 70s.  High pressure returns behind that cutoff low and we’ll see temperatures rise once again towards the weekend.  By then highs could peak in the 15-20° above average range as forecast highs are in the mid 80s as of right now.
