Key MESSAGE 1, The Arctic airmass will keep temperatures below normal through Thursday. Today, highs will be in the upper 40s/low 50s with ample sunshine. Lows Thursday morning will again dip to the lower end of guidance (NBM10) as dry high pres will be centered overhead. Given that we've had very warm temps over the past several weeks, precautions should be taken to protect any vulnerable plants through Thursday.

KEY MESSAGE 2, We'll gradually warm from late-week through the weekend. On Thursday, temperatures will moderate to around or to only slightly below avg, in the upper 50s to low 60s (low 50s OBX). By this weekend, inland temperatures will be back into the upper 70s/low 80s with the beaches reaching the mid 60s to low 70s. Chances for precipitation will remain <15% through the weekend. While dry, fire weather concerns should remain rather low due to benign winds forecast through the weekend with high pres dominating.

KEY MESSAGE 3, Our next front isn't expected until later Sunday night or Monday, which will bring our next chance for showers and a resultant cooldown behind back door cold front. Models have trended stronger with aforementioned nnerly wind surge, esp near the coast. Pops have been raised into the 30-40% range early to mid next week behind the fropa.
