Marine Weather and Tide Forecast for North Cape May, NJ

NEAR TERM /THROUGH TODAY/
Decent radiational cooling conditions are underway tonight due to clear skies and light winds. The winds could be just enough to prevent all areas from radiating as efficiently as previous nights. Regardless, another cold night and Friday morning is expected, though fortunately not as cold as previous nights now that the airmass is modifying. Lows mainly in the mid to upper single digits (near zero in the usual colder spots) and teens.
No cold weather headlines are warranted at this time.

For Friday, another benign weather day is expected across the Mid-Atlantic region. A decaying cold front will gradually approach from the west around midday, however no precipitation is expected as the front is quite moisture-starved. Other than just a slight increase in cloudiness with cold air advection filling in behind the front, no significant change to the weather is expected. In wake of the front, expansive high pressure will build in late in the day from the southwest. High temps should top out in the upper 20s to mid 30s.

SHORT TERM /TONIGHT THROUGH SUNDAY/
A cold front passes through the region Friday evening, and then cold air advection will be underway, and with skies clearing out late, and winds becoming nearly calm, there will be one last bitterly cold, frigid night on tap. Lows will generally be in the single digits to around 10 for most of the area, though strong radiational cooling conditions may result in even colder localized spots.

Highs on Saturday will be similar to Friday, topping off in the upper 20s to low 30s, which are some 10 degrees below normal.

High pressure over the Southeast and Mid-Atlantic on Saturday will slide offshore, and then high pressure reestablishes itself over the Midwest and the Ohio and Tennessee Valleys on Sunday.
Temperatures finally warm up to above freezing for most of the area with highs in the upper 30s north and west of the Fall Line, and in the low 40s for areas along, south and east of the I-95 corridor, and in the mid 40s in southern Delmarva.

LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/
The Long Term period will feature zonal flow at the surface with weak troughiness aloft a a closed H5 low will meander over Hudson Bay and northern portions of the Province of Quebec.
Several strong shortwaves will dive into the base of the trough over the Northeast during this time, and this will drag several weak cold fronts through the region. Arctic air remains bottled well to the north, with a brief warm up to above normal temperatures for the first half of the new week and then a return to normal temperatures towards the end of the week.

The first cold front passes through the region Sunday night producing generally mid-level cloudiness, and then skies will be mostly sunny on Monday. Lows will be in the upper teens and low 20s Sunday night, and then highs on Monday will be in the upper 30s to low 40s, though in the upper 40s in southern Delmarva.

A stronger shortwave passes north of the area Tuesday night through Wednesday morning, and this will be strong enough to allow surface low pressure to develop over the Great Lakes, and this low moves through New York and New England before moving over the Gulf of Maine and departing on Wednesday. A strong cold front will follow behind in. In terms of sensible weather, most of the area will be dry from Tuesday through Wednesday.
However, the combination of snow showers associated with the low and cold front, as well as Lake Effect Snow bands developing upstream, should spread far enough south to get into the southern Poconos and far northwest New Jersey starting Tuesday afternoon. Although the 13Z/23 NBM does not have PoPs, the 12Z CONSALL has slight chance PoPs for the northern half of the forecast area, and chance PoPs for the southern Poconos and far northwest New Jersey. NBM is too dry, and the CONSALL is probably too wet at this point, but will go ahead and introduce slight chance PoPs for snow showers Carbon and Monroe counties and Sussex county (NJ) from Tuesday afternoon through Wednesday morning.

After temperatures warm to above normal levels into Tuesday, temperatures fall back to near and just below normal normal levels for Wednesday and Thursday as reinforcing cold fronts pass through the region.

AVIATION /06Z FRIDAY THROUGH TUESDAY/
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.

Through 12Z...VFR/SKC. West-southwest winds around 5 kts or less. High confidence.

Friday...VFR with a few clouds during the afternoon. West- northwest winds around 10 kt. High confidence.

Friday Night through Tuesday...VFR. No significant weather.

MARINE
No marine headlines are in effect through Friday. West- northwest winds around 10-15 kt this afternoon will increase to around 15-20 kt tonight and persist through Friday. Seas of 2-3 feet. Fair weather.

Due to the combination of cold air/water temperatures and gusty winds, periods of light freezing spray are likely to develop tonight into Friday morning.

Outlook...

Friday night through Tuesday...Brief SCA conditions are possible Saturday night, then again Sunday afternoon. Otherwise, sub-SCA conditions until late Monday night and Tuesday. There should be a reduction in ice coverage into the weekend and early next week as temperatures begin to moderate compared to this past week. There will still be a chance for some light freezing spray Friday night into Saturday morning.
