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 State College PA 242 PM EDT Sun Jul 5 2020
SYNOPSIS. A summertime weather pattern will continue across the Commonwealth, with hot temperatures continuing for much of this week. Widely scattered thunderstorms are possible most afternoons this week.
NEAR TERM /THROUGH TONIGHT/. Nearly full sunshine across the CWA this afternoon. Radar showed a short lived isolated showers across SW Adams County that quickly dissipated as it moved south of the state. The big story is the wide range of surface dewpoint temperatures. Areas across the northern half of the CWA have seen DP temps fall into the upper 40s and lower 50s in spots. While to the south it's still quite muggy with dewpoints well in the 60s.
SHORT TERM /MONDAY THROUGH MONDAY NIGHT/. Mostly clear with just thin high level clouds. Valley fog will develop but should remain fairly benign and diminish quickly Monday morning. The proximity of a weakening back-door front from later Monday afternoon into Tuesday should combine with a destabilizing environment (ML CAPE of 1000-2000 j/kg) to touch off scattered showers and thunderstorms. Although organized severe storms are not anticipated with generally weak vertical shear foreseen, the presence of some dry air aloft and steep low-level lapse rates may promote localized strong wind gusts from some of the more robust cores.
LONG TERM /TUESDAY THROUGH SATURDAY/. Anomalous, high amplitude ridge moving east from the Central U.S. and Upper Miss Valley will flatten out as it reaches the Appalachians by Tuesday and Wednesday of next week. This weather feature will bring an increase in heat, along with an uptick in humidity.
A chance for a mid afternoon to early evening shower or thunderstorm can't be ruled out as we head into the middle of next week as minor disturbances aloft slide by near or just to the north of the region.
Much of central PA will have a shot at reaching 90 degrees for max temps for much of next week. There is still uncertainty on just how many days of 90 degree plus temperatures any one spot will string together, as cloud cover and pop up showers or thunderstorms could keep temps down a few degrees. Please see the climate section below for details on past heat waves in central PA.
Longer range guidance hints at a weakness under the ridge and maybe a coastal low developing by next weekend. As an upper trough digs down towards the low, there will be a chance for unsettled weather next weekend.
AVIATION /19Z SUNDAY THROUGH FRIDAY/. Any visibility reductions will rapidly improve this morning. High pressure will pass directly over Central PA Sunday afternoon, suppressing almost all cloud development and eliminating any chance for precipitation. Expect most locations to remain cloud-free for much of the day with, at most, scattered fair weather cumulus across southwest airfields.
Patchy valley fog again possible late in the TAF period toward daybreak on Monday, which could cause vis reductions to MVFR.
Mon-Thu . Hot daytime temperatures will persist through the week. Isolated SHRA/TSRA possible, mainly afternoon and early evening hours.
CLIMATE. A sustained period of above-average temperatures is expected over the next 7 to 10 days. A heat wave is defined as 3 or more days with temperatures greater than or equal to 90 degrees. Here are some facts about previous heat waves from Harrisburg (MDT) Williamsport (IPT), and State College (STC), which have climate periods of record dating back to the late 1800s.
Longest stretch of consecutive 90 degree days: IPT: 15 (July 4 - July 18, 1988) MDT: 11 (5 times, most recently July 22 - August 1, 1999) STC: 15 (July 4 - July 18, 1988)
Annual occurrences of 90 degree days: Average Most (Year) Least (Year) 2020 (thru 7/4) IPT 16 42 (1988) 0 (1979) 4 MDT 20 60 (1966) 3 (2004) 5 STC 8 35 (1988) 0 (11 times) 1* *Highs at STC are officially reported the next morning, whereas the others are reported at midnight.
How common are stretches of 5 or more consecutive 90 degree days? IPT: 15 times since 2000 (12 of 20 years) MDT: 19 times since 2000 (12 of 20 years)* STC: 4 times since 2000 ( 4 of 20 years)
*MDT had a stretch of 10 straight 90 degree days from July 3 - July 12, 2012. If highs on Saturday and Sunday can hit 90 degrees, we could make a run at 10 straight days exactly 8 years later.
CTP WATCHES/WARNINGS/ADVISORIES. None.

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.
