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.

SYNOPSIS. Cool and dry high pressure will continue to build south over the region through Tuesday. The high will then weaken and shift south and east, allowing temperatures to gradually warm to near normal by the end of the week. Rain chances will be on the increase as well late in the week.
NEAR TERM /THROUGH TUESDAY/. As of 1036 PM Monday: The cu field that moved across the Charlotte metro area early this evening failed to dissipate at sunset, and instead has morphed into a blob of stratocu trapped under the subsidence inversion that is being advected westward toward the Blue Ridge Escarpment. Chances are increasing that once this moisture reaches the Blue Ridge, we will contend with it for the rest of the night. Temps were in relatively good shape for now, but the cloud cover will affect low temps if it hangs around.
Otherwise, anomalously strong high pressure remains over New England, maintaining a breezy northeast flow into the CWA. The high looks to weaken and shift southward tonight as it comes between a trough crossing Ontario and Hurricane Teddy south of Nova Scotia. The result will be weaker winds in the PBL and more of our CWA decoupling nocturnally. Cooler min temps can be expected overall, and some patchy high-elevation frost is fcst particularly in light of the reduced wind. It is not expected to be widespread enough for an advisory. Pleasant and dry weather will continue through Tuesday, with highs beginning to climb back up slightly under the modifying air mass.
SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/. As of 215 PM EDT Monday: The cool and dry sfc high pressure will continue to weaken and begin to shift east Tuesday night thru Wednesday, as a baggy upper trough combines with the remnants of TC Beta to our west. Wednesday looks like the last completely dry day of the week, with some increasing cloudiness thru the day. Temps continuing a gradual warming trend, but still below normal.
Wednesday night thru Thursday, moisture begins to increase as deep- layer southerly flow develops. Guidance still wants to bring some light showers in the extreme western zones by daybreak Thursday, but look overdone per dry low-levels in the fcst sndgs. Showers should begin to ramp up in at least the western half of the FA on Thursday, This along with thickening clouds should result in temps being a category or so cooler than Wednesday. But lows will be near normal.
LONG TERM /THURSDAY NIGHT THROUGH MONDAY/. As of 230 PM EDT Monday: Confidence continues to increase that relatively unsettled weather will be in store for the region thru most of the medium range. A split upper flow regime sets up across the eastern CONUS, with a slow-moving southern stream trough crossing the Ohio Valley Friday. Another southern stream trough deepens over TX on Saturday and drifts NEWD thru Sunday, as a northern stream trough digs into the Upper Midwest. The 12Z GFS and ECMWF disagree on the details, and the EC has had a swath of heavy QPF across some portion of the region over the last few runs. But for now, confidence in an excessive rain/flood threat still looks low. While the remnants of Beta will enhance the moisture, PWATs will generally be around 1.5-1.75"(around +2 SD anomaly). An in-situ wedge may form by early friday and persist thru most of the weekend, until a stronger cold front pushes in from the west. And the better instability may remain south and keep the heavy rain threat south of the area. In any case, max temps will remain near to slightly below normal, while mins will be above normal under plenty of clouds. PoPs are mainly in the high-end chc to likely range for now, due to uncertainty on timing periods of greatest chcs for rainfall.
AVIATION /03Z TUESDAY THROUGH SATURDAY/. At KCLT and elsewhere: Other than the possibility of a fog/stratus restriction at KAVL around daybreak, conditions should be VFR through the period. Still a few gusts out there at sunset, and a few cu on the east side of Charlotte, but both should go away in the next hour. Clear sky and light NE to N wind overnight. Think at least an MVFR restriction is a good bet at KAVL in the pre-dawn hours and cannot rule out the VLIFR seen in the guidance, but confidence is only high enough to go temporary IFR around daybreak. Wind will be light and variable Tuesday morning as high pressure settles in. The guidance suggests bringing the wind direction around to SW in the afternoon in most places, except KCLT, which may remain light WNW. Some cirrus should invade from the west late in the day.
Outlook: VFR conditions expected thru at least Wednesday, with the exception of the typical fog/stratus risk near KAVL around daybreak. Confidence is increasing that the remnants of Tropical Storm Beta could bring precipitation and restrictions later in the week.
