Marine Weather and Tides
12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed.
10/9/2019 Updated the Marine Zones.
9/4/2019 Fixed the weather maps due to NOAA moving them.

AREA FORECAST DISCUSSION National Weather Service Charleston WV 727 PM EDT Tue May 26 2020
SYNOPSIS. Very warm, and humid for mid week, beneath summer-like upper level ridge. Tropical disturbance Wednesday night into Thursday. Cold front Friday night/Saturday, followed by high pressure.
NEAR TERM /THROUGH WEDNESDAY/. As of 720 PM Tuesday .
Made some minor tweaks to bump up sky coverage this evening, otherwise, no changes required at this time.
As of 236 PM Tuesday .
A highly amplified upper pattern is in place with an upper level ridge across the eastern US and a deep upper low/trough across the country's midsection. Southeast flow in-between these two features has led to another warm day across the area and many locations should finish the day around 10 degrees above normal. Otherwise, conditions are fairly quiet today with satellite trends showing an increasing cu field across the region, but so far it appears that the influence of the upper level ridge and poor mid level lapse rates have generally suppressed any convective activity today. However, latest regional radar imagery does show that convection has developed to our south and west across eastern/central KY and central/western OH where the better quality moisture/instability is present. As a result, if we manage to see any convection today in our area, thinking it would occur across northeast KY/southern OH and possibly southwest VA so have added just slight PoPs in these areas, but overall coverage should be very isolated. Latest SPC mesoanalysis does suggest that SBCAPE values have reached 1000-1500 J/kg across western portions of the CWA so this will be where the best potential for any development exists, but thinking we should remain dry elsewhere for the remainder of the day given the lack of any appreciable forcing. If any convective activity does develop, these will once again be slow moving storms with heavy downpours and gusty winds being the primary hazards.
With high pressure off to our northeast, a light ESE flow tonight will be in place tonight and this should keep low stratus locked in place along the eastern slopes of the Appalachians. In addition, thinking there is at least some potential for valley fog again tonight, particularly in the deeper northern mountain valleys around Elkins as forecast soundings show a strong inversion developing off the surface. Otherwise, high and mid level clouds will be on the increase overnight from south to north as a coastal system moves into The Carolinas on Wednesday. This system is then expected to move northward through the afternoon and evening with precipitation chances increasing from the south by the end of the near term period. There still remains quite a bit of uncertainty with the track this system will take as it will be situated between a slow-moving closed low across the lower Mississippi Valley and the aforementioned upper ridge in the western Atlantic. Regardless, the majority of the area should be mainly dry through Wednesday afternoon, but expecting PoPs to increase from the south by the end of the period as the system approaches the region.
SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/. As of 205 PM Tuesday .
Remnants of a weak tropical disturbance are progged to move north across the Carolinas and into Virginia Wednesday night into Thursday. Models are divided on the trajectory of this feature. While the ARW/RUC/Canadian/GFS takes the bulk of QPF north along the east side of the Appalachians, the NAM/SREF and ECMWF suggest precipitation could reach our lowlands Wednesday night.
This disturbance will bring an increase in sfc dewpoints generally in the mid to upper 60s mainly east of the Appalachians. While the bulk of moisture and associated precipitation seems to stay way east of our area, lots of shear and streamwise vorticity can be expected to move over the area. This could produce needed forcing to initiate showers and thunderstorms Thursday afternoon and evening. Moderate to heavy rain can be expected under H850 theta-e values reaching 340 K. Convection could initiate over elevated heat sources along our eastern mountains Thursday afternoon.
Meanwhile, an upper-level low pressure system slowly approaches from the southwest Thursday night into Friday. This low will bring tropical moisture from the Gulf of Mexico to the OH Valley and WV Friday, for showers and thunderstorms likely into the weekend. These two system could pose a threat for heavy rain during the second half of the week into the weekend.
Temperatures should remain above normal throughout the short term period.
LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/. As of 205 PM Tuesday .
By Friday night, an upper low pressure, within the southern stream, gets absorbed by a northern stream trough reaching the OH Valley early Saturday. This trough will push a cold front to increase shower activity through the period. However, the timing of the front is not ideal for thunderstorms as the front crosses Friday night into Saturday.
Temperatures will remain above normal through Friday. Temperatures will drop behind the cold front to about normal values through the weekend. For the beginning of the work week, flow should turn northerly as ridging takes over leading to drier conditions and seasonable temperatures.
AVIATION /00Z WEDNESDAY THROUGH SUNDAY/. As of 128 PM Tuesday .
Mid and upper level cloudiness will continue to increase across the region through the overnight hours as moisture from a disturbance off the coast of Northeast Florida streams into the area. With ample cloud cover overnight and a little better boundary layer flow, should see minimal risk for fog formation, with any patchy fog confined to the more protected mountain valleys. Ceilings continue to lower through the day Wednesday with some rain knocking on the door by the end of this TAF period, but VFR conditions are expected to prevail until that time.
Winds remain light and southeasterly through the period.
