Marine Weather and Tides
8/26/2020 The 7 day forecast is taking about 5 seconds to load but it will eventually load. NOAA is still working on it.
8/18/2020 NOAA continues to have trouble. Wind guest will occasionally be left off graphs. I am working with NOAA to resolve the issue.
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.
7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports.

AREA FORECAST DISCUSSION National Weather Service Charleston WV 313 AM EDT Mon Sep 21 2020
SYNOPSIS. High pressure maintains dry weather and plenty of sunshine for the first half of the week. Weak system Thursday/Friday brings rainfall to the south.
NEAR TERM /THROUGH TONIGHT/. As of 305 AM Monday .
River valley fog is currently developing across much of WV, E KY, and SW VA (per GOES 11.2-3.9 micrometer imagery) thanks in part to cool ambient air temps over warm water temps. This fog should gradually mix out by mid morning with cobalt blue skies then prevailing for the remainder of the day, as high pressure continues to influence area weather.
Max temps this afternoon should be very similar to yesterday's values. Interestingly, all 00z guidance came in a little cooler than previous runs for today's highs . perhaps due to a brief backing of the 925mb flow during the early/mid afternoon hours. Given the very dry airmass, I still think the warming potential exits to reach (or get very close to) Sunday's highs.
Tonight also features more of the same. Unseasonably cool temps and areas of frost across the NE CWA. Have undercut guidance by a coupe of degrees for overnight lows, owing to a continued very dry airmass in place.
SHORT TERM /TUESDAY THROUGH THURSDAY NIGHT/. As of 245 AM Monday .
High pressure dominates until Wednesday when the ridge flattens and the blocking pattern weakens and eventually falls apart allowing the area to be vulnerable once again. Thursday is when moisture is finally back and advected in from the southwest associated with a cut off low forecast to spawn a system over Texas. This fairly stacked system will affect us by late Thursday raising chances for unsettled weather and adding POPs from slight to chance as the system rides along to our south with the northern half of the area mainly avoiding most of the action. Chances for showers will be confined along the southern mountains and the extreme south along with low probability for thunderstorms into Friday until its associated upper level trough exits completely. Not a whole lot of moisture/PWATs with this system about average for this time of year so not expecting a lot of rainfall accumulations, if any.
LONG TERM /FRIDAY THROUGH SUNDAY/. As of 245 AM Monday .
Chances of showers will remain for the rest of Friday then high pressure briefly builds in for Saturday although there will be chances for showers later in the day as another disturbance to the south funnels warm moist air into the region. For late Saturday into Sunday, a broad trough will move in from the west, originating from the Pacific, and will eventually bring a stout upper level cutoff low in. Southerly flow along with a disturbance in the south, which will merge with the aforementioned system, will continue to bring moisture in from the Gulf. A surface low will form in the wake of the main feature as it amplifies which will push a cold front closer to the area promoting showers all day Sunday. An increase in POPs and thunderstorm probability will be on tap as the frontal band pushes through into Monday. PWATs are 2 standard deviations above normal, therefore rain chances and higher amounts will be on the higher side of average. Accepted central guidance since models seem like they have a good handle on the system as far as timing and intensity goes and added in just a tad more likely POPs for Sunday.
AVIATION /07Z MONDAY THROUGH FRIDAY/. As of 1257 AM Monday .
River valley fog development is starting to occur across the region, per GOES imagery. This should eventually lead to IFR or worse conditions at KCRW/KEKN and possibly KPKB. Elsewhere, lack of moisture and slightly stronger 925mb wind fields should preclude anything but VFR conditions.
All aerodromes should be VFR by mid morning Mon with mainly clear skies prevailing from thereon.
Weak ENErly sfc winds 5kts or less overnight, exception being KBKW where more prevalent ESErly flow of 5 to 10 kts will be common.
FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 06Z TUESDAY . FORECAST CONFIDENCE: High for KBKW/KHTS/KCKB. Medium elsewhere.
ALTERNATE SCENARIOS: Timing of onset of fog may be slower than what TAFs currently indicate.
