Synopsis
Surface high pressure remains off the NC coast through the end of the weekend. A weak cold front will push across the area Monday night. High pressure returns Tuesday.

Near Term - Until 6am This Morning
As of 945pm EDT Saturday... Pleasant weather continues this evening as surface high pressure remains immediately off the NC coast. Mostly clear as SCT-BKN mid level clouds over the mountains have struggled to move ewd. Temperatures are milder than the past few evenings ranging from the upper 60s to mid 70s. Another comfortable night is expected, though not as cool as the past couple. Lows in the low/mid 60s.

.SHORT TERM /6am THIS MORNING THROUGH TUESDAY/... As of 205pm EDT Saturday... Turning a bit warmer Sunday with increasing S flow...resulting in highs 85-90F inland and low to mid 80s near the coast.

Surface hi pressure becomes elongated ENE-WSW from the warning Atlantic to the SE CONUS and ridge aloft flattens out by Mon. At the same time...an upper trough moves E from the Great lakes to the St Lawrence Valley. Locally...Monday will be very warm w/ SW winds and partly to mostly sunny conditions. Probability of Precipitation remain aob 10% through the day with highs in the m-u80s...around 90F from I 95 W to over the Piedmont.

A cold front will be entering the mountains Monday afternoon which may throw a bit more significant cloudiness into the Piedmont by late in the day. The front will be weakening significantly as it exits the mountains Monday evening with the best moisture and dynamics staying well to our N. Will have 20-30% Probability of Precipitation confined to the N and NE sections of the FA (for ISOLD/SCT SHRAs-tstms)...w/ Probability of Precipitation at or below 14% elsewhere. Lows Monday night ranging from around 60F NW to the upper 60s SE.

Clearing out and not warm nor as humid Tuesday as winds turn NW ahead of surface hi pressure building E through the OH Valley. Highs mainly in the l80s...u70s at the coast.

Long Term - Tuesday Night Through Saturday
As of 150pm EDT Saturday... Other than a small opportunity for isolated SHRAs-tstms w/ a (weakening) cold front Thu...dry weather and temperatures averaging aoa normal will prevail through the extended forecast period.

Highs Wednesday min the u70s E to 80-85F inland...mainly 85-90F Thu...in the l80s at the coast and m80s inland then from 80-85F at the coast to the m-u80s inland Sat. Lows in the m50s-l60s Tuesday night...l-m60s Wednesday night and m-u60s Thu and Fri nights.

Marine
As of 330pm EDT Saturday... Surface high pressure is just off of the NC coast this afternoon and lee trough over the VA Piedmont, giving us winds S 8-13 kt along the Atlantic coast. SCA (Small Craft Advisory) will be allowed to expire at 4pm for the oceans zones along Delmarva as seas are continuing to subside to below SCA (Small Craft Advisory) threshold. As of this afternoon, it appears the SCA (Small Craft Advisory) for the southern zones will be allowed to expire on time as well. However, buoy 44014 is still reporting sig waves of 6-7 ft.

Winds are expected to remain south 8-15 kt through the weekend. An upper trough will be over the eastern Great Lakes Sunday, which will tighten the pressure gradient over region as a surface high remains off the coast and another lee trough develops in the Piedmont. This will lead to winds S 13-18 kt on the Chesapeake Bay, and S 18-22 kt for the northern ocean zones and S 15-20 kt for the southern zones. Wind gusts may reach SCA (Small Craft Advisory) threshold for oceans zones off the Maryland coast and in the Chesapeake Bay Sunday night through Monday morning.

A cold front will approach the area from the NW late Monday night/Tuesday morning. Winds will turn NW 10-15 kt behind the front then decrease to NW 5-10 kt Tuesday evening as the center of surface high pressure move near.

Winds will remain light and variable Wednesday as the surface high moves slowly off our coast. Winds will once again turn south on Thursday as a front approaches the area once again at the end of the week.
