.WHAT HAS CHANGED... Nothing.

.KEY MESSAGES... - 1) Tranquil weather is expected through the middle of the week with climbing temperatures.

- 2) A cold front will approach on Friday, leading to cooler and potentially unsettled weather for the weekend.

KEY MESSAGE 1...Tranquil weather is expected through the middle of the week with climbing temperatures.

Low overcast will persist through tonight with some spotty drizzle here and there. Some patchy fog is possible west of the Blue Ridge Mountains, but widespread low clouds will likely prevent fog from becoming dense and/or widespread. Residual moisture may remain trapped beneath the subsidence inversion with weak gradients on Tuesday, although deeper mixing will likely support more breaks of sun.

With ridging building in at the surface and aloft and light sfc winds, pattern will become more conducive for fog development, if skies clear enough. This appears more likely to happen late Tuesday night into Wednesday morning.

Temperatures will climb further Wednesday and Thursday, with more locations reaching the 80s. Some spots could even reach the upper 80s by Thursday. Developing southerly flow will lead to more sunshine. Dry weather is expected both days. With light winds and elevated dew points, some patchy fog could form during the overnight hours.

KEY MESSAGE 2...A cold front will approach on Friday, leading to cooler and potentially unsettled weather for the weekend.

Surface high pressure begins to slide offshore Thursday into Friday. Above-normal temperatures likely persist into Friday afternoon with temperatures approaching the upper-80s as upper-level ridging slowly breaks down ahead of an incoming cold front from the Great Lakes. This front could slowly begin to pass through the Mid-Atlantic by Friday evening before stalling just off to the south.

This front could potentailly linger throughout the weekend before finally pushing offshore towards the start of next week. This will lead to a much cooler weekend overall, along with chances for intermittent showers as the front lingers over the Mid- Atlantic. Rainfall probabilities remain lower (20%-40%) at this time given the weak nature of the front and remaining uncertainty in the model guidance. As this front pushes offshore, conditions could begin to clear early next week, with daily highs returning to the 60s and lower 70s in the wake of the front.

Marine
High pressure moving toward the area will provide light winds Tuesday and Wednesday. A northwesterly direction will turn southerly on Wednesday.

Southerly winds begin to pick up in strength on Thursday, with some channeling effects bringing gusts to near 20 knots over the more southern waters.

A passing cold front could bring wind gusts up to marginal SCA (Small Craft Advisory) thresholds Friday and into Saturday. Winds shift northerly by Friday evening.

Tides / Coastal Flooding
Some uncertainty exists for the remainder of the week as guidance indicates anomalies will stagnate close to 1 foot above normal. As long as it stays near this value, most locations should remain below minor flood thresholds. However, Annapolis could have minor flooding for some tide cycles depending on how exactly the water levels fluctuate.
