Once again, a warm southerly flow has allowed temperatures to rise in the mid and even upper 70s most places with 60s at the beaches. A diurnal cu field has formed, not as extensive as yesterday, as ample low level moisture advection continues off of the ocean. A few very light returns have appeared on radar but no ground truth of any precip actually touching the ground yet. Considering the very dry air aloft and lack of triggers, will be keeping pops today below mentionable levels. For tonight a light southerly flow will continue with high pressure dominating the western Atlantic. Lows will be in the mid 50s for most locations. Model soundings suggest another partly cloudy yet dry day as the moist southerly low level flow continues around the western Atlantic ridge. Temperatures will remain above normal with highs in the mid to upper 70s most places. A few places will hit 80.

Another in a series of dampening shortwaves will move across the Tennessee Valley and Mid Atlantic region through the period with a a cold front trailing at the surface. We continue to advertise low chance pops for the daytime hours Tuesday with slight chance either side of this to address any timing issues. The front will cross the area in the early morning hours of Wednesday. Thermal profiles look slightly warmer than recent days with the southwest flow ahead of the system. Depending on the amount of sunshine Tuesday, there could be widespread 80s. Overnight lows remain entrenched in the 50s.

A light south to south-easterly flow of around 10 kts will continue through the near term as high pressure continues its hold over the western Atlantic. Winds near shore this afternoon and Monday afternoon will be a little bit higher, in the 10 to 15 kt range, and gustier as the afternoon sea-breeze circulation sets up. Seas will remain right around the 3 ft range through the period. SHORT TERM /MONDAY NIGHT THROUGH TUESDAY NIGHT/...

Very light winds from the south, southeast initially will become better defined through the day Tuesday as a cold front approaches from the west. Not the most overpowering flow however as speeds increase to 15-20 knots briefly before backing off Tuesday evening as the front loses some of its identity. Significant seas will increase from initial 2-4 foot values to 3-5 feet Tuesday afternoon and evening with the increase in winds. LONG TERM /WEDNESDAY THROUGH FRIDAY/... as of 4 AM Sunday...Light winds Wednesday in wake of a cold front can be expected, followed by a wind-shift to the N_NE Wednesday night as a back door cold front pushes across the 0-20 NM waters. Briefly this intrusion will transition to light wind as the high moves overhead Thursday afternoon. A strong and progressive southern system will bring increasing SE-S winds late Thursday and an Advisory may very well be needed for 25 KT gusts late Thursday night ahead of its cold front. Strong storms and numerous showers appear likely on the water Friday. && .ILM WATCHES/WARNINGS/ADVISORIES... SC...None. NC...None.
