Area Forecast Discussion National Weather Service Newport/Morehead City NC 1003 PM EST Mon Jan 20 2020

SYNOPSIS. Cold high pressure will prevail across the region for most of the week. Low pressure and its associated cold front will impact the area this weekend.

NEAR TERM /UNTIL 5 AM TUESDAY MORNING/. As of 10 PM Monday . Forecast continues in good shape with minimal changes for this update. Some clouds continue to skirt the immediate coast and will keep the very small chance of rain/snow flurries in the forecast overnight as shallow moisture persists with a weak trough offshore. Any precipitation would be very light with no impacts expected.

Very chilly air to remain in place over the next few days. Lows tonight will drop into the low/mid 20s area-wide, and gusty north winds will push wind chill values into the teens.

SHORT TERM /5 AM TUESDAY MORNING THROUGH 6 PM TUESDAY/. As of 3 PM Mon . Arctic high pressure will continue to build over the area from the west, while upper low pushes through the Carolinas aiding in sfc cyclogenesis well to the south off the coast of FL. Weak coastal trough will push towards the NC coast, which could trigger some isolated showers along the coast. Can't rule out some flurries or very light snow showers along the coast (mainly OBX) first thing in the morning, but not expecting any impacts. Wind chill values in the teens for most locations Tue morning. The gradient will tighten between the high and low, with northerly wind increasing through the day, strongest along the coast. Issued Wind Advisory for the Outer Banks, where could see gusts to 45 mph develop late afternoon into Tue night. Low level thickness values and northerly flow support temps well below normal, with highs again in the upper 30s to low 40s. Breezy northerly winds combined with cold temperatures, will keep wind chill values in the 20s to low 30s.

LONG TERM /TUESDAY NIGHT THROUGH MONDAY/. As of 300 PM Mon . Settled and cold conditions persist into Thursday ahead of the next storm system, which will impact the area Thursday night into the weekend.

Tuesday night through Thursday . High pressure will continue to build in from the west, while a low pressure system develops off the Florida coast Tuesday night into Wednesday. Though, it will be mostly dry across the area, except for the immediate coast from Cape Lookout to Hatteras as modest low level moisture under a northerly flow. Additionally, the gradient will tighten as the high encroaches from the west and the low remains parked offshore, with gusty north winds on tap, especially for the Outer Banks, later Tuesday through Tuesday night.

CAA will remain strong through midweek, with highs Tuesday near 40 away from the beaches, and lows once again well into the 20s for most Tuesday night. Airmass moderation begins as the high builds closer Wednesday, but temps will still be several degrees below normal despite mostly sunny skies.

The ridge will move overhead Thursday, bringing lighter winds/weaker CAA and continued mostly clear conditions aside from some cirrus streaming overhead. Temps will be within a couple degrees of normal.

Friday and Saturday . Friday will be a transition day as heights aloft fall in response to troughing digging across the central US. At the surface, ridging will slide offshore as a complex frontal system works toward the eastern seaboard. Moisture transport will bring increasingly clouds, with rain chances dependent on the erosion of mid-level dry air/subsidence, which looks to persist through the day Friday, limiting POPs to slight chance in the forecast. However, deep moisture transport ensues by Friday evening, with high-end chance POPs in the forecast ahead of the approaching frontal system Friday night and Saturday. While specifics of the system remain uncertain, as longer range guidance is inconclusive about the track of the surface low and the potential for a secondary low/wave to develop closer to the area, confidence is beginning to increase in the general timing of the precip. Additionally, ensemble guidance indicates that most solutions bring instability into the area ahead of the primary front Saturday, and slight chance thunder has been introduced into the forecast for the eastern half of the area.

Sunday and Monday . Mild high pressure builds in from the southwest Sunday into early next week, resulting in mainly dry conditions and near-seasonable temps.

AVIATION /03Z TUESDAY THROUGH SATURDAY/. Short Term /through 00Z Wednesday/ . As of 655 PM Monday . VFR conditions expected at all TAF sites through this cycle. Some lower stratus may linger along the Outer Banks and Downeast Carteret County with a very small chance of flurries, but minimal impact expected. May issue with aviation will be the continuation of gusty north winds tonight into Tuesday. Wind gusts to 20 knots or greater will possible at times, especially Tuesday. A dry airmass will preclude any potential for fog overnight.

Long Term /Tuesday night through Saturday/ . As of 300 PM Mon . VFR conditions and mostly clear skies prevail into Friday. Gusty north to northeast winds are possible at times later Tuesday night into Wednesday.

MARINE. Short Term /through Tuesday/ . As of 10 PM Monday . Gusty north winds continue at late evening with gusts as high as 31 knots at Diamond Buoy and well into the 20s elsewhere. Seas continue in the 5-7 foot range. Arctic high pressure will continue to build over the area from the west, while upper low pushes through the Carolinas aiding in sfc cyclogenesis well to the south off the coast of FL. The gradient will tighten between the high and low, with northerly wind increasing tonight and through the day Tuesday. Upgraded to Gale Warnings for the coastal waters and Pamlico Sound, with SCAs for the Alligator/inland rivers, and Albemarle/Croatan/Roanoke Sounds beginning late Tue morning and afternoon. N winds 20-25 kt tonight with seas building to 6-9 ft, highest north of Ocracoke. Northerly winds 20-30 kt Tue morning, increasing to 25-35 kt by late afternoon. Seas 6-9 ft Tue morning building to 7-11 ft late.

Long Term /Tuesday night through Saturday/ . As of 300 PM Mon . High pressure pushing into the area from the west as low pressure develops well off the Southeast coast will result in a tightening of the gradient Tuesday night. Given the cold airmass advecting into the area, stronger winds should mix readily to the surface, brining solid gales to the coastal waters and larger inland waterways Tuesday night. Seas will continue to build Tuesday night, and peaking around 6-12 ft early Wednesday morning. Conditions will gradually improve Wednesday into Thursday as the high builds overhead, but elevated seas persist across the coastal waters mainly south of Oregon Inlet. Winds begin to veer and increase Friday as the high moves offshore and a frontal system approaches from the west Friday night into Saturday.

TIDES/COASTAL FLOODING. As of 3 PM Mon . Gusty north to northeast winds Tuesday into Wednesday morning could cause minor water level rises across the southern Pamlico Sound from Hatteras Island to the Lower Neuse River, with inundation of around 1 ft or less possible for very low lying areas. Additionally, low pressure moving from off the Southeast coast toward the central Atlantic could result in elevated tide levels on the ocean and near inlets mid-week into the weekend.

MHX WATCHES/WARNINGS/ADVISORIES. NC . Wind Advisory from 4 PM Tuesday to 7 AM EST Wednesday for NCZ203>205. MARINE . Small Craft Advisory from 10 AM Tuesday to 11 AM EST Wednesday for AMZ136-137. Gale Warning from 11 AM Tuesday to 10 AM EST Wednesday for AMZ135. Small Craft Advisory until 1 PM EST Wednesday for AMZ131-230- 231. Gale Warning from 11 AM Tuesday to noon EST Wednesday for AMZ152-154-156-158. Gale Warning from 4 PM Tuesday to 7 AM EST Wednesday for AMZ150.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
