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.
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 Wilmington OH 334 PM EST Wed Feb 19 2020
SYNOPSIS. High pressure will bring colder temperatures and mainly dry weather tonight through Friday. Expect milder temperatures on the weekend as the flow turns southwest behind the high. Precipitation returns late Sunday through Monday ahead of the next low pressure system.
NEAR TERM /THROUGH TONIGHT/. Weather map has an upper trough to the northwest, with a 1045mb surface high positioned over the northern plains behind the upper trough axis. The dry airmass and downward motion accompanying this system will produce no precipitation tonight. We could see increasing clouds late tonight in the vicinity of the right front quadrant of a jet streak arriving ahead of the trough axis. Fog is not likely to form due to scant moisture and slightly increasing surface winds late tonight. Near normal lows ranging from around 20 north to the mid 20s central and the upper 20s far south will be observed by daybreak.
SHORT TERM /THURSDAY THROUGH THURSDAY NIGHT/. Mainly dry weather conditions are expected as the upper trough axis pushes through while the surface high settles through Iowa and Missouri. A modest amount of low level humidity and upward motion in a shallow layer capped at 5000 ft will produce clouds and possibly a few snow flurries; otherwise no precip is forecast.
The main story may be chilly temperatures resulting from a prolonged period of cold advection coming on the northerly flow ahead of the large high. Afternoon readings ranging from the upper 20s north, around 30 at DAY and CMH, and up to the mid and upper 30s south will be around 10 degrees below normal. Lows in the mid and upper teens are forecast at all sites Thursday night.
LONG TERM /FRIDAY THROUGH TUESDAY/. A very dry airmass will encompass the Great Lakes and Ohio Valley Friday into Saturday. Surface high pressure of Arctic origin will settle across the Ohio and Tennessee Valleys on Friday. The high will then move to a position near the southeast U.S. coast Saturday evening. Sunny days and mainly clear nights are forecast. After a cold start Friday morning, bountiful sunshine will allow temperatures to warm into the lower 30s north to the upper 30s south. Lows Friday night will be cold once again, generally 15 to 20. Southerly return flow, airmass modification, and abundant sunshine will boost temperatures into the lower 40s north to the upper 40s south on Saturday.
Short wave energy is still forecast to eject northeast from the southern Plains to the Ohio Valley Sunday into Monday. There are some timing differences in the models in regards to pcpn onset. Also, there are differences in the strength and location of the associated surface low. All in all, it appears most of Sunday will remain dry with thickening clouds. Pcpn chances will ramp up from southwest to northeast Sunday night as low level moist/covergent ascent teams up with approaching upper dynamics. Pcpn is expected to be mostly in the form of rain Sunday night and again on Monday. The weather system will move east through the region on Monday with continued high PoPs. By Monday night, pcpn will taper off from west to east as our area will be in the wake of the system. It will be relatively cold Sunday morning with mild conditions expected Sunday into Monday (highs in the 40s to near 50).
For the remainder of the extended forecast, Tuesday into Wednesday, models try to develop a large scale mid level trough across the Great Lakes and Ohio Valley. This pattern will bring another chance of pcpn during this period. This should be in the form of rain with the chance of snow mixing in by Wednesday night as much colder air advects southeast into the region.
AVIATION /19Z WEDNESDAY THROUGH MONDAY/. Looks like VFR should persist with high pressure centered to the northwest. Cloud cover starting as cirrus will be enhanced overnight in the vicinity of an upper level jet streak, with altocumulus and possibly cumulus forming. Models show increasing low level humidity, but perhaps not enough to produce MVFR ceilings, so kept cumulus layer as SCT025 for now. Continued VFR should be observed on Thursday as high pressure settles over Iowa. Winds mainly from the north will likely remain high enough to prevent BR from forming.

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.
