Area Forecast Discussion National Weather Service Newport/Morehead City NC 644 AM EST Fri Jan 17 2020

SYNOPSIS. Strong high pressure will build over the region today before another strong front impacts the area Saturday into early Sunday. Cold high pressure then dominates the region for early next week.

NEAR TERM /TODAY/. As of 640 AM Friday . No appreciable changes to the forecast. Mountain cirrus continues to stream across mainly northern zones but this will dissipate later this morning.

Prev disc . Amplified pattern continues to develop over the CONUS this morning with synoptic ridging building over the central U.S. and an upper trough digging into the Great Basin. This ridge will gradually shift east and be placed over the Carolinas by tonight with broad subsidence aloft. At the surface, strong polar high pressure was analyzed over the Great Lakes and will remain in place over the eastern CONUS for the period.

Temperatures early this morning have not dropped as fast as forecast, likely due to a combination of slowly dissipating mountain cirrus and weaker than anticipated low-level CAA. Adjusted up near term temperatures several degrees but still expect all locales except portions of OBX to reach the 30s before sunrise.

CAA will continue today before subsiding tonight as upper ridge shifts overhead. With plenty of subsidence aloft expect skies to be mostly clear apart from cirrus beginning to filter in late with the next round of low pressure developing over the central CONUS, as well as typical CAA-regime stratocumulus along the Outer Banks. 1000-850mb thicknesses of around 1290 m favor highs only in the low to possibly mid 40s, and with gusty winds it will feel even colder. Strong winds over OBX will continue today and wind chills there may not crack 30.

SHORT TERM /TONIGHT/. As of 320 AM Friday . Winds subside tonight as upper ridge and surface high pressure shift over the Carolinas. With clear skies excellent radiational cooling conditions will initially be present and expect temperatures to rapidly fall in the early evening. Main sticking point will be the aforementioned increasing cirrus associated with central U.S. cyclogenesis which could slow or stall falling temperatures overnight. Favored coolest guidance minus a degree or so and expect most inland area lows to reach the upper 20s, low to mid 30s OBX.

LONG TERM /SATURDAY THROUGH THURSDAY/. As of 230 AM Fri . Another cold front with limited moisture will cross Sat night and early Sunday with cold high pres following most of the upcoming week.

Saturday through Sunday . High pressure will slide off the coast Saturday morning with winds veering to southerly ahead of the next front during the afternoon. The SSW winds will become quite gusty late Saturday thru Sat night . espcly coast. Clouds will increase and decks will lower through the day with a chance for some prefrontal showers in the afternoon. The best coverage for showers will occur overnight Saturday . moisture is limited and expect light QPF amounts but will cont with low likely pops Sat night. Any lingering shra coast early Sunday will push offshore by midday. Ahead of the front Sat expect highs mainly 55 to 60. The best cold air advection holds off til late Sunday and expect temps again to be in the 50s with some lower 60s south.

Monday through Thu . Arctic high pressure will establish itself over the area during the first part of next week and hold temperatures well below average. A robust shortwave will dip south Monday night into Tuesday that will need to be watched. 00Z models cont to differ with GFS/Canadian progressive with little or no chc of precip. The ECMWF conts to have a much more amplified pattern aloft resulting on some precip near imd cst Tue into early Wed. Given uncertainty will cont with just slight chc pops imd cst. Airmass is cold but appears lower lvls remain above freezing across OBX so just have rain as ptype. By Thu hgts build aloft in wake of short wave but sfc high pres cont to the W with cool NNE winds cont.

Highs Mon and Tue wl be mainly in the 40 to 45 dgr range . warming slowly to lower 50s by Thu. Lows will be in the 20s inland to 30s beaches.

AVIATION /12Z FRIDAY THROUGH TUESDAY/. Short Term /through 18z Friday/ . As of 645 AM Friday . High cirrus continues just north of all terminals this morning but gradually dissipate in the next few hours. Main concern for the period are gusty N winds with some gusts to 20 kt likely. Mid-level clouds and cirrus coverage increase overnight as next system takes shape to the west. VFR conditions prevail through the period.

Long Term /Saturday through Tuesday/ . As of 230 AM Fri . VFR conditions are expected Saturday as clouds grad lower with some sct shra late ahead of approaching cold front. A few pds of sub VFR poss Sat night as cold front approaches with sct to numerous shra. VFR returns Sun as drier air grad spreads in behind front. VFR will cont Mon and Tue with cold high pres building in from the W.

MARINE. Short Term /Today and Tonight/ . As of 330 AM Friday . Gale conditions now overspreading northern and central coastal waters with 35+ kt gusts being observed as far south as Diamond Shoals. Seas have built rapidly in the past several hours with 11-12 foot seas reported in the same stretch of waters, and 6 foot seas for srn waters. Local wave guidance poorly captured this and had to manually adjust wave heights up a few feet in the forecast. Gale conditions will come to an end by this afternoon as high pressure gradually shifts over the waters but seas will likely remain above 6 feet by the end of the period for all but srn waters. SCA conditions over rivers and sounds end by evening with NE winds quickly weakening to 5-10 kt.

Long Term /Saturday through Tuesday/ . As of 230 AM Fri . Winds become srly Sat as high pres slides offshore with speeds ramping up to 15 to 25 kt late. SSW winds peak 25 to 35 kts ahead of front Sat night with some Gale conditions likely. As front crosses later Sun winds become NW mainly 15 to 20 kts. N winds 15 to 20 kts Mon increase to 20 to 25 kt Tue as pres drops a bit offshore with approaching short wave. Seas of 3 to 6 ft early Sat drop below 6 ft all waters briefly mid day them ramp up to 5 to 8 ft by evening. Seas peak 8 to 12 ft outer wtrs Sat night then slowly drop to 5 to 8 ft Sun. Seas of 4 to 6 ft early Mon drop to 3 to 5 ft late. As N winds increase Tue seas build to 5 to 7 ft.
