| Area Forecast Discussion National Weather Service Newport/Morehead City NC 628am EST Sat Dec 13 2025 Synopsis Weak high pressure slides through today. A strong cold front will cross the region Sunday, with strong and cold high pressure building back in through Monday. High pressure shifts offshore by the middle of next week with moderating conditions expected. Another cold front moves through Thursday night. Near Term - Today As of 3am Sat...Heights/thicknesses rise ahead of a strong cold front as swrly winds inc today. This will bring much warmer conditions (briefly) with highs expected to reach the 60s inland. The cold shelf waters will keep the beaches chilly in the 55-60 range. Short Term - Tonight As of 3am Sat...Much warmer tonight as WAA (Warm Air Advection - the movement of warm air) strengthens ahead of approaching cold front. Temps will range from the 45-50 range northern tier to the low 50s south. Cold front will reach the FA by morning, thus the daytime highs will be realized around sunrise Mon, wherein temps fall quickly through the day Mon. Long Term - Sunday Through Friday As of 3am Sat... Key Messages... - Strong cold front to move through Sunday with sharply falling temps and breezy conditions through afternoon. - Dangerous cold expected with wind chills in the 5-15 degree range Sunday night/Monday morning. Sunday through Sunday night...A closed low will travel across the Great Lakes region through the weekend with a robust upper trough digging across the East Coast and an attendant cold front pushing across the area Sunday. Moisture is somewhat limited but favorable jet dynamics and strong frontal forcing should be sufficient to bring some precipitation across the area. Most guidance a bit drier than NBM, so overly eager NBM probability of precipitation have been toned down to the 50-70% range, highest chances southern and eastern areas. Bulk of precipitation is rain, but a stray flake or two may mix in with rain as precipitation comes to an end in the afternoon. No impacts with warm ground in place and meager moisture. Aforementioned high temps should be realized in the morning Sunday, before plunging through the 30s in the afternoon hours. Breezy conditions develop in tandem with the strong cold air advection, and it will feel quite raw by late day. Coldest night of the season thus far will be realized Sunday night/Monday morning. Guidance and thicknesses suggest lows 15-20 interior zones, with 20s OBX zones. Very well mixed atms will prevent lows from reaching their lowest potential, and where NBM is usually too warm on lows with radiational cooling, it tends to be a couple degrees too warm on well mixed nights. Have forecast a multi model MOS blend as a result. With the wind in place, apparent t's will reach the upper single digits to low teens for most, and likely a cold wx advisory will be needed. Monday...Arctic high traverses ENC with cold and brisk temps expected. Highs in the 30s area-wide. Breeziest conditions expected through the morning, then winds abate later in the day. Monday night expected to be cold once again, and with very dry atms and light winds in place, temps should reach the lower end of guidance, with teens interior zones and 20s nearer the coast. Light return flow may kick in later in the night with temps leveling off. Tuesday through Thursday...High pressure slides offshore Tuesday with SW flow returning bringing a warming trend through mid week. Precip chances increase Thursday (20%) and Thursday night (30-40%)with a cold front approaching and moving through the region. Highs expected in the 40s Tuesday, 50s on Wednesday, and 60s on Thursday. Friday...Cold front pushes east by week's end, with dry conditions returning. Trough will be low amplitude and thicknesses/heights don't drop too drastically. Therefore temps will cont mild behind the frontal passage. with above climo readings expected. Marine As of 3am Sat... Key Messages - Gale conditions Sunday afternoon through Sunday night for nnwrly winds 30-40 kt expected. Through Tonight Good boating conditions will persist in the short term through today as high pressure eases offshore.

Remainder of the waters will remain under a strong marine inversion and 10-15 kt expected. Seas in the 2-4 ft range through tonight. Sunday through Sunday night...Strong Cold Air Advection begins Sunday with passage of arctic front. Winds build to gales first in the coastal waters north of Ocracoke Sunday afternoon, and have upgraded to gale warning here. Rest of the waters, sounds, and Alligator River build to gales Sunday night, and remain in a 4th period gale watch. Seas peak 6-10 ft in the relatively short-lived gale Sun night.
