National Weather Service Newport/Morehead City NC
615am EDT Sunday September 22 2019

High pressure centered over the area will slowly drift offshore today, keeping the area seasonable and dry. A dry cold front will cross the area Tuesday with high pressure building back in through the rest of the work week.

.NEAR TERM Through Tonight
As of 615am Sunday...No changes to previous thinking. Deep layered high pressure will remain over the area through tonight producing dry weather with sunny skies, warm temperatures and light winds. Any patchy/shallow fog that forms early this morning will dissipate rapidly after sunrise. Highs will continue their upward trend reaching the lower to mid 80s across the region.

.SHORT TERM /MONDAY THROUGH 6am MONDAY/... As of 255am Sunday...Clear skies and light winds will prevail across Eastern NC tonight as high pressure remains in control. Can't rule out some shallow fog patches developing after winds decouple, but low level moisture is very shallow so not expecting widespread coverage overnight. Lows will be 60-65 which is warmer than past few nights.

Long Term - Monday Through Saturday
As of 3am Sunday...A robust shortwave approaches the area Monday and crosses the area Monday night into Tuesday with an attendant cold front moving across the area Tuesday. Models have varied with the timing of the front over the past several model cycles so confidence in the timing isn't that high. Moisture still looks limited however with best dynamics staying north of the area and guidance continues to show little to no precipitation and will keep minimal Probability of Precipitation in the forecast. Temps are expected to be near to a few degrees above normal Monday and Tuesday.

Dry and warm conditions continue through the rest of the week as high pressure builds back into the area Tuesday night and Wednesday with near zonal flow aloft. The high then slides offshore Wednesday night and Thursday with a ridge building aloft bringing additional warming. A backdoor cold front approaches the area late in the week and may push into the area Friday, though guidance has not in best agreement with how far south the front will push. Moisture and dynamics remain limited and guidance is primarily dry so keeping Probability of Precipitation low. Temps expected to be several degrees above normal much of the period and could see high around 90 inland Thursday and Friday. The exception being NE section/OBX if the aforementioned front pushes into the area bringing onshore flow.

Short Term Through Tonight
As of 615am Sunday...Light SW/S winds 5 to 15 kt (highest north of Oregon Inlet) will prevail across the waters through tonight as high pressure remains over the area. Diminishing long period swell will persist with 2-4 ft seas through tonight.

Long Term - Monday Through Thursday
As of 330am Sunday...High pressure will be centered offshore Monday with S to SW increasing to 10-15 kt. A cold front is forecast to push across the waters Tuesday with winds becoming N to NE around 5-15 kt. High pressure migrates across the area Tuesday night and Wednesday with wind around 10 kt gradually veering to E to SE by late in the day. Winds veer to SW and increase to 10-15 kt Wednesday night and Thursday

Seas will be around 2-4 ft Monday, then build to 4-6 ft Monday night through Tuesday night as swell from TC Jerry move into the waters. Seas are expected to subside back to 2-4 ft Wednesday afternoon through Thursday.
