Another clear, somewhat cool and dry morning then warming into the upper 80s to lower 90s this afternoon as easterly winds become breezy at times.
.Prev /issued 455am EDT Sunday September 22 2019/
Deep layer ridging over the eastern CONUS continues as the primary influence over the region providing east-northeast flow across the peninsula while advecting drier air into the area. PW of 1.17 inches observed during the 00Z evening upper air sounding suggests moisture remains limited throughout the atmospheric column, and guidance suggests at least another few days of similar conditions as the overall pattern gradually de-amplifies into the work week.
The eastern CONUS ridging will flatten out a bit and sink south through mid-week as a mid/upper trough currently over the Intermountain West and Upper Plains pushes east into the Great Lakes and southeastern Canada. Surface high pressure currently centered over the Mid-Atlantic coast...which has been responsible for our breezy/gusty conditions of late...will gradually become displaced further east off the Atlantic seaboard as a result, allowing the gradient over our area to relax with gradually diminishing winds locally. Ridging is once again expected to build over the eastern CONUS as the week draws to a close, reinforcing east to northeast flow across the peninsula and offshore waters.
Overall, pleasant conditions are expected through the week with a gradual warming trend as the week progresses. For now it appears that any appreciable rain chances/PoPs will be absent across the area until after mid-week at best. After beginning the week within a few degrees of normal, temperatures will gradually warm a bit more above normal for early autumn by mid-week, with highs in the low to mid 90s and lows in the lower 70s.
High pressure to the northeast maintains brisk east- northeast flow across coastal/offshore waters into early week before relaxing gradient gradually allows winds to subside into mid-week. SCA (Small Craft Advisory) remains in effect until 12Z for Gulf waters for winds/seas 20 kts/5 ft...then diminishing to around 15 kts/2-4 feet late morning...diminishing further to around 10-15 kts/2-3 ft into mid-week.
High pressure to the northeast maintains filtering of drier air into region under east-northeast flow, although RH values should remain above critical thresholds. Aforementioned dry air will preclude any significant rain chances through much of the week. Only area of concern remains high dispersions associated with gusty winds continuing through the day Sunday.
