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. |

The low is anticipated to pass off the virginia coast on Sunday morning, then it should move slowly out to sea. A cold front approaching from the northwest is expected to arrive on Monday night. The boundary is forecast to stall to our southeast for the middle and late parts of the new week.

SYNOPSIS. High pressure will nose into our region from the northeast today. Meanwhile, low pressure is forecast to develop in the Carolinas before moving northeastward. The low is anticipated to pass off the Virginia coast on Sunday morning, then it should move slowly out to sea. A cold front approaching from the northwest is expected to arrive on Monday night. The boundary is forecast to stall to our southeast for the middle and late parts of the new week.
NEAR TERM /UNTIL 6 PM THIS EVENING/. For today, high pressure will remain across eastern Canada and try to nose its way down the east coast into the Mid-Atlantic region, while a cold front will remain to our south through the day. Meanwhile, the flow aloft will shift from a westerly direction, to more of a southwest flow by the afternoon. Several short wave/vorticity impulses will move across the area through the day as well. Despite these short waves/vorticity impulses, much of the day is expected to be mostly rain free as the high nosing down into the area will likely keep drier air in place. However, late in the afternoon there could be some showers developing for portions of our western and southern zones as moisture begins to increase as the flow shifts to the southwest.
SHORT TERM /6 PM THIS EVENING THROUGH 6 AM SUNDAY/. An area of low pressure will move along the frontal boundary to our south from the Carolinas, to near the mouth of the Chesapeake Bay by daybreak Sunday. As the low lifts northward, a surface trough may develop on the northern side of the low and move across our area overnight. As the low lifts northward and approaches our area overnight, moisture will be increasing north of the low, especially across eastern Maryland, Delaware, and southern New Jersey where PW values approach and exceed 2 inches. Enhanced lift will move across the area as well as there will be several short wave/vorticity impulses moving across the area. As these features move across the area overnight, rain is expected to spread across much of the area, with the heaviest precipitation across the southern areas where the greatest lift and higher moisture combination will be. There is not much in the way of instability, so we do not have thunderstorms in the forecast, although a few rumbles of thunder cannot be ruled out.
LONG TERM /SUNDAY THROUGH FRIDAY/. A mid level trough is forecast to slide eastward from the Great Lakes on Sunday, settling over the northeastern states for Monday, Tuesday and Wednesday. The feature is expected to lift to the northeast late in the week. The pattern will keep temperatures from getting excessively warm. Highs should favor the 70s on Sunday, and the 80s during the new week.
Surface low pressure is forecast to be centered near the mouth of Chesapeake Bay on Sunday morning. It is expected to drift northeastward to a point about 100 miles off the southern New Jersey coast on Sunday evening. The cloud and precipitation shield associated with the system is anticipated to affect our weather on Sunday. We are expecting a mostly cloudy sky along with rain showers. The rain may become moderate to heavy for a time in parts of northeastern Maryland, Delaware and southern New Jersey. Those areas may also experience a few rumbles of thunder. The potential for significant rainfall and thunder decreases in eastern Pennsylvania, and central and northern New Jersey, farther from the low.
As the low moves out to sea on Sunday night, the precipitation and clouds should follow.
A cold front is forecast to approach from the northwest on Monday and it will likely arrive in our region on Monday night. Scattered showers and thunderstorms are possible.
There remains some uncertainty as to how far the cold front will progress to our southeast before stalling. It appears as though relatively dry air will work its way into our region for Tuesday. However, the boundary may drift back toward us for Wednesday and Thursday, bringing a chance of showers and thunderstorms at that time.
AVIATION /08Z SATURDAY THROUGH WEDNESDAY/. The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.
Today . VFR conditions prevail through today, although clouds will thicken and lower through the day. Winds begin the day out of the northeast 5-10 knots, then become easterly during the day with gusts around 15-20 knots from I-95 south and east, before shifting to the southeast late in the afternoon. High confidence.
Tonight . VFR conditions start off during the evening hours, but ceilings will lower to MVFR later in the evening and overnight as rain begins to move into the area. IFR conditions are possible by daybreak for portions of southern New Jersey, Delaware, and Maryland as rain becomes heavier. Winds begin the evening out of the east to southeast around 5-10 knots, then shift to the northeast overnight around 5-10 knots.
Outlook .
Sunday . VFR/MVFR conditions with rain showers. IFR conditions are possible around KMIV and KACY where the rain may become heavy at times. Northeast wind around 10 knots. Medium confidence.
Sunday night . Conditions improving to VFR with showers ending. Northeast to north wind around 10 knots. Medium confidence.
Monday . Mainly VFR. A chance of afternoon showers and thunderstorms. Northwest wind 5 to 10 knots becoming southwest. Medium to high confidence.
Monday night . Mainly VFR. A chance of evening showers and thunderstorms. Southwest wind 5 to 10 knots becoming northwest. Medium to high confidence.
Tuesday . Mainly VFR. Northwest wind 5 to 10 knots. Medium to high confidence.
Tuesday night . Mainly VFR. Variable wind 6 knots or less. Medium to high confidence.
Wednesday . Mainly VFR. South wind 5 to 10 knots. Medium confidence.
MARINE. Today-Tonight . Small Craft Advisory remain in effect for the Atlantic Ocean coastal waters as seas are expected to increase to 5- 6 feet today and continue into tonight. Winds may also gust around 25 knots later today into tonight.
Outlook .
Sunday . A Small Craft Advisory is in effect for our ocean waters and for Delaware Bay. A northeast wind 15 to 25 knots with gusts up to 30 knots is expected.
Sunday night . A Small Craft Advisory is in effect for our ocean waters. A northeast wind 15 to 20 knots with gusts up to 25 knots is expected.
Monday . Wind speeds and gusts are forecast to fall below 25 knots. However, wave heights on our ocean waters may remain around 5 feet, especially in the morning.
Monday night through Wednesday . No marine headlines are anticipated.
Rip currents .
For today, there is a moderate risk for the development of dangerous rip currents. Northeasterly winds will be 15-20 mph with gusts to around 25 mph. Breaking waves should be 3 to 5 feet with a medium period swell from the southeast.
For Sunday, there is a high risk for the development of dangerous rip currents. Northeasterly winds continue 15-20 mph with gusts to around 25 mph. Breaking waves building to 4 to 6 feet are anticipated with a short to medium period mainly wind wave from the east.
TIDES/COASTAL FLOODING. The northeast flow along the coasts of New Jersey and Delaware this weekend will continue to cause water levels to build gradually. Astronomical tide heights will be on the increase as we approach Tuesday's new moon. The evening astronomical high tides are generally about a foot to a foot and a half higher than those in the morning.
Tidal departures were mainly in the +0.7 to +0.9 foot range this morning along our coast. With the expected gradual increase today, it continues to appear as though we will see spotty minor flooding with this evening's high tide. It should not be widespread enough to warrant a Coastal Flood Advisory.
As tidal departures rise even further, we may see a more extensive minor flooding event with Sunday evening's high tide. An advisory may become necessary as we get closer to that high tide cycle.
PHI WATCHES/WARNINGS/ADVISORIES. PA . None. NJ . None. DE . None. MD . None. MARINE . Small Craft Advisory until 6 AM EDT Monday for ANZ450>453. Small Craft Advisory from 8 AM this morning to 6 AM EDT Monday for ANZ454-455. Small Craft Advisory from 6 AM to 6 PM EDT Sunday for ANZ430- 431.
