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 Pittsburgh PA 326 AM EST Tue Feb 25 2020
SYNOPSIS. Periodic rain is expected through Wednesday with crossing low pressure. Colder weather and snow showers are then expected to end the week.
NEAR TERM /UNTIL 6 PM THIS EVENING/. An upper trough across the Central CONUS/Plains region is expected to deepen today. A series of shortwaves in SW flow aloft ahead of the trough, and ascent on the nrn side of a weak OH Valley sfc low, should maintain occasional rain across the region today. Included the "occasional" wording in the forecast to indicate numerous breaks in the rain. Highs are expected to be around 10 degrees above average.
SHORT TERM /6 PM THIS EVENING THROUGH THURSDAY NIGHT/. Rain should taper off tonight as shortwave support and deep layer moisture decreases. The deepening Central CONUS/Plains trough is progged to approach the Upper OH Valley region Wednesday, as a sfc low redevelops across the OH Valley in response. Showers should overspread the region again with the approach and passage of the trough.
The sfc low is expected to track to the Lower Great Lakes by late Wednesday, pulling its associated cold front across the region. Rain should change to snow Wednesday night in the cold advection behind the front.
Another digging trough is expected to move out of South Central Canada and the Nrn Plains late Wednesday, and persist across much of the Eastern CONUS through Thursday night. Shortwaves rotating through the trough, along with less than optimal lake and terrain enhancement in wrly boundary layer flow, should maintain scattered snow showers through Thursday night. Generally expect an inch or less of snow for much of the area, with a couple of inches possible N of I 80 and in the higher terrain E-SE of PIT.
Gusty wind is expected Wed night through Thu night with a tightening pressure gradient behind the exiting sfc low, and mixing in cold advection, with the highest gusts around 40 mph in the higher terrain.
LONG TERM /FRIDAY THROUGH MONDAY/. The upper trough is progged to remain across the Eastern CONUS through part of Saturday, maintain periodic scattered snow showers. More lake/terrain enhancement is possible Sat as the flow veers to the NW, though the trough axis is expected to shift east through the day, with sfc high pressure also building in, ending the snow showers.
Model ensembles then indicate ridging should build in through Monday with mainly dry weather expected. Temperatures are expected to be 10 to 15 degrees below average over the weekend, but return to more seasonable levels by Monday.
AVIATION /08Z TUESDAY THROUGH SATURDAY/. Passage of a shortwave overnight will spread light rain and MVFR conditions across the region, with most visibility restrictions minor given the initially dry low levels. Although rain will taper off initially towards sunrise, ceilings will continue to slowly lower. Expect IFR restrictions to develop from southwest to northeast during the day in continued moist advection, with additional rain expected during the day. IFR should then be maintained for the rest of the TAF period, although some slight improvement is possible near and south of the Mason/Dixon line by midnight.
Outlook. MVFR/IFR restrictions in rain and low clouds will continue Wednesday. A changeover to snow showers and cold northwest flow will then keep restrictions in the forecast into Friday.

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.
