High pressure returns to the region briefly today with warm temperatures and clear skies. A couple of weak disturbances Monday and Tuesday keep things somewhat cool and unsettled. Dry and warmer conditions return Wednesday through the middle of the week. The next disturbance approaches towards the end of the week in to the weekend.

Near Term - Through Tonight
Dense fog early this morning has now mostly dissipated, with any lingering patchy fog expected to dissipate by 5AM. The frontal boundary that crossed the area this morning is forecast to stall well south of the area, with a weak high building across the central Appalachians and Mid-Atlantic today. Breezy northwest winds could gust up to 25mph at the higher elevations and along/north of Interstate 66. Abundant sunshine will help afternoon temps reach the 60s to lower 70s, except for 50s along the Allegheny Front. Winds decrease quickly this evening as high level clouds build in from the west. Lows tonight settle in the 40s.

Short Term - Monday Through Tuesday Night
The work week starts out cloudy and showery as a weak mid-level shortwave trough and associated surface low pass to the north of the area. A warm front quickly lifts north through our area, bringing an increase in moisture and shifting winds to easterly. The highest rain chances (50-60pct) are forecast along the Alleghenies, with around 40-50pct elsewhere. Afternoon temperatures will range from the mid 50s along the MD/PA border to upper 60s in central VA.

A cold front crosses the region Monday night as high pressure builds over the area on Tuesday. Cooler air that filters in behind the front Monday night will drop temps to the mid 30s to lower 40s. Near normal highs on Tuesday as highs reach the 50s, with around 60F in central VA and 40s for the Alleghenies. Another mid-level shortwave trough is forecast to reach the Mid-Atlantic Tuesday afternoon, and it could bring a few showers to the Alleghenies. However, no accumulation is expected. A few showers are possible south of I-66.

Tuesday night lows are forecast to drop below freezing in the Alleghenies, with mid 30s to around 40F elsewhere.

Long Term - Wednesday Through Saturday
For Wednesday through the end of the week an upper ridge develops over the central CONUS and pushes east towards the region. Meanwhile surface high pressure slides eastward as well and eventually pushes offshore late week. Temperatures will gradually rise throughout this period, with a return to above normal temperatures possible by Friday.

A trough begins to develop over the central CONUS towards the end of the week and pushes towards the Great Lakes on Saturday. A warm front associated with this system could bring some showers back into the region as early as Friday night.

The associated cold front eventually traverses the region on Saturday, but looks to be rather dry and lacking significant forcing at this time. Do expect well above average temperatures on Saturday though in the wake of the warm front Friday night.

Small Craft Advisories are in effect for the upper Tidal Potomac and central to northern Chesapeake through this afternoon for winds gusting up to 25 knots. Conditions quickly improve this evening as winds decrease.

Sub-SCA (Small Craft Advisory) conditions are expected Monday. SCA (Small Craft Advisory) conditions are possible again late Monday night into Tuesday.

Winds on Wednesday and Thursday have come down in intensity from what was expected over the past couple of days, but SCA (Small Craft Advisory) conditions remain possible. Wednesday night provides the best shot as southerly winds channel up the Chesapeake Bay. Winds on Thursday will likely be a bit stronger, with SCAs (Small Craft Advisories) a bit more likely.

Tides / Coastal Flooding
Tidal anomalies have remained elevated this morning, thus the more sensitive tidal locations could reach action stage for the next couple of high tide cycles. No flooding is expected at this time.
