Area Forecast Discussion National Weather Service Newport/Morehead City NC 714 AM EDT Fri Apr 10 2020

SYNOPSIS. Cool high pressure will build over the eastern United States today and Saturday. A strong area of low pressure will push a warm front across the area Sunday into Monday, followed by another cold front approaching the coast by the middle of next week.

NEAR TERM /UNTIL 6 PM THIS EVENING/. As of 710 AM Friday . Some patchy high clouds across the region at daybreak, otherwise generally clear skies. Sprawling cool high pressure centered over Nebraska will continue to build south into the Carolinas today. Expect much cooler and drier air eastern NC today with highs generally in the upper 50s to lower 60s, accompanied by gusty NNW/N winds, gusting as high as 25-30 knots this afternoon, perhaps up to 35 knots coast. A few high clouds may impact the area early today with high-based fair weather cumulus possible in the afternoon.

SHORT TERM /6 PM THIS EVENING THROUGH 6 AM SATURDAY/. As of 405 AM Friday . With clear skies and diminishing wind tonight, the main issue will be unusually chilly temperatures for early April. Dewpoints will drop into the low/mid 20s this afternoon, but should recover to around 30 degrees later tonight. Almost all numerical guidance supports lows in the mid 30s, and given about a 5-7 degree temperature/dewpoint spread, would not expect much in the way in frost. Dayshift can monitor the situation, but not inclined to issue a Frost Advisory at this time with lows tonight in the mid/upper 30s with mid 40s Outer Banks.

LONG TERM /SATURDAY THROUGH THURSDAY/. As of 315 AM Friday . High pressure will continue to bring drier and brings drier and cooler conditions through Saturday. The next storm system will impact the area Sunday into Monday with another low forming off the SE coast mid week bringing additional rain.

Saturday . The high will become overhead across the region, then slide offshore Saturday afternoon with southerly flow returning. This will allow low-level thicknesses to increase and temperatures to reach into the 60s, though it will still be below-normal temps for this time of the year.

Sunday through Monday night . A significant shortwave over the Southern Plains will lifts towards the Carolinas, while becoming absorbed into the northern stream Sunday night into Monday as there is a sfc low over the Central Plains. The attendant surface low lifts from the Tennessee Valley across the Midwest, bringing a warm front across eastern NC Sunday with embedded disturbances aloft, prompting scattered showers to develop Sunday afternoon, though models have trended drier.

However, the best WAA does not get going until Sunday night into Monday morning, when the gradient tightens locally and a notably strong 40-50 kt LLJ moves over the area, bringing very strong low level theta-e advection. Despite the unfavorable diurnal timing, instability will quickly climb to 1000-1500+ J/kg, and showers with some embedded thunderstorms are likely during Monday morning. Strong gradient winds are expected along the coast, with gusty/damaging winds in the strongest storms possible across the entire area as ample low level shear could allow for convection to become organized. Some variability regarding timing remains between long range guidance members, and the severe threat will be further refined in subsequent forecasts. Heavy rainfall is also possible at times, though individual storms should be progressive enough to preclude a widespread flash flooding threat.

The cold front will push through Monday night with rain diminishing from west to east with a cooler and drier airmass moves in the west.

Tuesday through Friday . The aforementioned cold front stalls well south of the area Tuesday, with high pressure bringing drier conditions and temps within several degrees of normal. Forecast confidence remains low as we move into the middle of next week, but model are indicating another low pressure system developing along the stalled frontal boundary and riding up the coast and bringing more unsettled weather for Wednesday. Afterward, conditions look to be dry for the remainder of the week.

AVIATION /11Z FRIDAY THROUGH TUESDAY/. Short Term /through 12Z Saturday/ . As of 710 AM Friday . No real changes to the forecast with high confidence in VFR conditions for this TAF cycle. Skiers should remain clear except for some patchy high clouds overnight and perhaps some high-based fair weather cumulus on Friday. Gusty N/NW winds will continue today and tonight. Sufficient low- level mixing should prevent any fog or stratus formation.

Long Term /Saturday through Tuesday/ . As of 335 AM Friday . VFR conditions will dominate Saturday, then unsettled weather. A prolonged period of flight restrictions and LLWS is possible beginning Sunday night and continuing into Monday as a strong frontal system impacts the area. Flight conditions will improve Tuesday.

MARINE. Short Term /Today and Tonight/ . As of 710 AM Friday . Winds are generally NW/NNW at 10-20 knots at daybreak with seas up to 4-5 feet. High-resolution guidance shows a significant surge of gusty winds to develop around 15z this morning with NNW winds of 15-25 knots expected with gusts of up to 30-35 knots at times this afternoon and evening. Have added the Alligator River, along with the other inland rivers to the SCA as those areas are also likely to pick up 15-25 knot sustained winds with higher gusts. Seas should build to as high as 6 feet by afternoon into tonight.

Long Term /Saturday through Tuesday/ . As of 340 AM Friday . High pressure will become overhead across the region with winds becoming less than 15 knots from the NW in the morning to SW by the Saturday afternoon. Winds will gradually increase through the day Sunday before becoming strong Sunday night into Monday as a strong cold front approaches from the west. Solid Gales expected Monday morning, with a period of storm force winds possible mainly for the coastal waters during the day Monday.

Seas will be around 2-4 ft, with sea subsiding further Saturday night. Marine conditions begin to diminish as southerly winds increase Sunday, with very dangerous and large seas emerging Sunday night into Monday as Gale to Storm force winds develop. Seas are expected to peak around 15-20 ft Monday afternoon. Seas will gradually subside through Tuesday morning, but remain elevated (above 6 ft), and further subsiding to around 4 ft Tuesday night.

FIRE WEATHER. As of 415 AM Friday . The combination of gusty N/NW winds of up to 20-30 knots, and low relative humidity values in the 20-25 percent range this afternoon will lead to an increased fire danger risk for all of eastern NC. |

MHX WATCHES/WARNINGS/ADVISORIES. NC . None. MARINE . Small Craft Advisory from 11 AM this morning to 8 PM EDT this evening for AMZ136-137. Small Craft Advisory until 5 AM EDT Saturday for AMZ135. Small Craft Advisory until 2 AM EDT Saturday for AMZ131-230- 231. Small Craft Advisory until 5 AM EDT Saturday for AMZ150-152- 154-156-158.

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.
