Marine Weather and Tides
Version 3.4 |
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. A backdoor cold front will move across the area this evening and overnight, then push to our south through Saturday. Another backdoor front may move into the area Sunday into Monday, before lifting back northward into Tuesday. A very warm and humid week is expected next week as a southerly flow develops, although there is the potential for a coastal low along the east coast late next week.
NEAR TERM /UNTIL 6 AM THIS MORNING/. The last of the convection is moving through extreme southern New Jersey and eastern portions of Delaware. All should be over in the next couple of hours.
Otherwise, drying out overnight but remaining warm and muggy. Skies becoming mostly cloudy as a stratus deck rotates in from northeast to southwest.
Lows tonight will only drop into the 70s for metro Philadelphia and Delmarva. Other areas will fall into the mid/upper 60s. Winds will become N to NE overnight. Patchy fog will develop, mainly across areas where rain fell.
SHORT TERM /6 AM THIS MORNING THROUGH 6 PM SUNDAY/. Following the weak front that crosses the area Friday night, drier and slightly cooler air will be across the area Saturday. This will probably be the most comfortable day of the next several with highs expected to remain in the 80s and dew points mostly in the 60s, so overall conditions will not be that oppressive. A minor vort max will drop south from nrn PA/srn NY during the afternoon. It's possible that a couple sct showers could develop, so we'll just keep the (mostly) slight chc pops in the afternoon fcst for now.
LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/. The long term period is forecast to be quite warm, with building humidity each day. Each day through the extended is forecast to be above normal. There is also a chance of rain each day, but it will not be a washout by any means.
On Sunday, the warm up beings again as the first backdoor front will be well to our south, before another approaches from the north. There is not much moisture forecast, nor any strong short wave/vorticity impulses expected, so Sunday is expected to be precipitation free.
By Monday, a second backdoor front approaches from the north, while moisture increases, along with a couple of short waves/vorticity impulses that may clip our northern areas. This could lead to a few scattered or isolated showers and thunderstorms during the afternoon.
By Tuesday, the backdoor front will move well to our north, and steady return flow will develop for Tuesday through at least Wednesday. This will keep warm temperatures across the area, but also lead to increasing humidity. Multiple short waves/vorticity impulses will move across the area for Tuesday- Wednesday, and will combine with an increase in moisture and lead to higher chances of showers and thunderstorms.
Questions return for the end of the week however. The ECMWF and Canadian show a coastal low moving northward along the east coast, while the GFS dissipates the low across the southeast states, but does push moisture across the Mid-Atlantic states. There will continue to be an enhanced chance for rain for Thursday through Friday.
AVIATION /04Z SATURDAY THROUGH WEDNESDAY/. The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.
Through tonight . Mainly VFR through around 06z. Development of an MVFR stratus deck around 2000 feet is expected in most areas after that time. Winds generally light and variable or light from the northeast. Moderate confidence.
Saturday . MVFR early then slowly diminishing CIGS with VFR in most areas (except coastal areas) by noon. NE to E winds 5 to 10 knots mostly. Medium confid.
Outlook .
Saturday night-Sunday night . Generally VFR expected.
Monday-Wednesday . Mostly VFR. A chance of showers and thunderstorms each afternoon and evening which may temporarily lead to lower conditions.
MARINE. Winds and seas will remain below SCA conditions tonight and Saturday. Any lingering thunderstorms will end. Winds will turn onshore tonight and remain E or NE into Saturday.
OUTLOOK .
Saturday night-Wednesday . Conditions expected to remain below advisory levels through the period, although winds could gust around 20 knots at times. There is a chance of showers and thunderstorms during the late afternoon and evening Monday- Wednesday.
Rip currents .
Today . Low Tomorrow . Low to moderate.
TIDES/COASTAL FLOODING. Astronomical high tide levels will continue to rise as there will be a full moon this weekend. The evening high tides are over a foot higher than those in the morning.
With high tides over, water levels continue to recede. The Coastal Flood Advisory expired at midnight.
Continued northeasterly and easterly flow could result in additional coastal flooding with the high tide cycles Saturday and Sunday evening in the same areas, though confidence is low at this time, so will hold off on extending the advisory for now.
For tidal portions of the Delaware River, at this point it looks like water levels will stay below advisory criteria, but will monitor the levels in the Delaware Bay closely this evening to see if it needs to be expanded.
Tidal flooding is not expected on the upper eastern shore of Chesapeake Bay.
EQUIPMENT. The NOAA Weather Radio All Hazards broadcast from Hibernia Park, PA (WNG704) remains off the air until further notice due to damage to the antenna during the June 3 Derecho.

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. |
