Synopsis for Eastern North Carolina coastal waters - AMZ100

National Weather Service Newport/Morehead City NC
248pm EDT Sunday Oct 25 2020

Weak low pressure will develop near the coast this evening and move offshore tonight. High pressure will dominate the weather early to mid next week before a complex frontal system and low pressure area impacts the area late in the week.

Near Term - Through Tonight
As of 245pm Sun... Short wave will push thru this evening and subsidence in its wake will bring an end to accumulating precipitation inland this evening. However, low pressure passing off the coast will continue to advect moisture in, overrunning the shallow post- frontal ridge/wedge. This moist layer will get compressed as mid level subsidence strengthens through the night, with very low stratus and drizzle expected to prevail through much of the night and stratus possibly building to the surface as fog occasionally. Scattered showers remain possible near the coast thru the evening and should diminish or end later tonight. Mild temps overnight given overcast skies, with mid/upper 50s inland to low/mod 60s beaches.

Short Term - Monday
As of 245pm Sun...Shld be dry as low pressure moves further offshore and high pressure builds in. Main question is how much sun we get as low clouds will be slow to lift/erode and may not see breaks til late if at all some spots. Leaned a bit twrd cooler guidance with upper 60s/lower 70s.

Long Term - Monday Night Through Sunday
As of 330am Sun...High pressure keeps settled weather conditions in place through mid week. A complex low pressure/frontal system will lift from the Gulf Coast and TN Valley then zoom across the eastern US, bringing the potential for unsettled weather Thursday into Friday.

Tuesday and Wednesday...High pressure should dominate this period, as fairly strong upper ridge will reside over the swarning Atlantic keeping dry and warm conditions in place over eastern NC. Continued above climo temps with highs in the 70s, possibly around 80 by Wed. Lows will be mainly in the 60s.

Thursday And Friday
Low pressure, which the National Hurricane Center currently expects to become tropical over the next 24-48 hrs, will lift from the Gulf Coast towards the interior eastern US later next week. The track of this low is highly uncertain, but the overall expectation is increased deep moisture transport across the Southeast and a more warm/humid/unsettled period as the tropical system gets absorbed in a fast moving shortwave that will move quickly eastward. Rainfall timing, amount, intensity, and the severe weather potential are low track dependent, and will be refined in subsequent forecasts. Have continued high chance probability of precipitation Thu into Fri.

Short Term - Through Tonight: As of 245pm Sun...Weak front is now thru most of the waters with only buoy 41025 showing SE flow. As weak low develops on front and pushes E winds will become NNE all waters and may see some gusts 15 to 20 kt late. On Monday high pressure will build in from the NW with mainly N winds 10 to 15 kt...possible a few higher gusts outer waters early. Seas cont to run above all guidance central and northern waters and currently are in the 6 to 8 foot range. Have extended the SCA (Small Craft Advisory) til midnight these waters and given trends later shifts may have to extend further in time. Think for Monday seas should be mainly in the 3 to 5 foot range.

Long Term /Monday night through Thu/... As of 330am Sat...High pressure dominates Tuesday and Wednesday, bringing more favorable marine conditions with light to moderate winds and 3 to 4 ft seas. Strong cold front and low pressure system approach on Thu, with winds and seas increasing to SCA (Small Craft Advisory) levels in strengthening swrly flow.
