SYNOPSIS. High pressure slowly builds across the region through the weekend before exiting Sunday afternoon. A series of low pressure systems moving up from the south look to affect the region for the early to middle part of next week. Low pressure should eventually depart to the north and east by late next Thursday into Friday.

NEAR TERM /UNTIL 6 AM SATURDAY MORNING/. High pressure extending from the southern Great Plains to the Ohio River Valley will continue to build eastward tonight. The air mass will bring a clear sky and a very light west wind to our region. Low temperatures will be in the teens and lower 20s.

SHORT TERM /6 AM SATURDAY MORNING THROUGH 6 PM SATURDAY/. The core of the area of high pressure is expected to be located in the southeastern states on Saturday. We are anticipating another sunny day.

A developing west southwest wind around 10 mph with gusts of 15 to 20 mph should begin to draw milder air into our region. Highs will likely favor the upper 40s and lower 50s in northeastern Maryland, Delaware, New Jersey, southeastern Pennsylvania and the Lehigh Valley. Readings should reach only the lower and middle 40s in the elevated terrain of the Poconos and far northern New Jersey.

LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/. Saturday night through Sunday night .

Dry and relatively mild conditions persist through this period as high pressure to our south slowly moves off the coast resulting in a SW flow. As a result, Saturday night will be milder than Friday night with lows mainly in the 20s to low 30s under mainly clear skies. This will be followed by sunshine for Sunday with highs mainly in the low to mid 50s except 40s over the southern Poconos. The quiet weather continues Sunday night as high pressure moves off the coast and low pressure approaches from the west. The continuing SW flow will result in overnight lows on the milder side for this time of year with lows mainly in the upper 20s to mid 30s.

Monday through Friday .

The pattern becomes unsettled for much of next week as a trough deepens in the east resulting in multiple waves of low pressure moving up from the south bringing mainly rain to the area. For Monday, low pressure will slowly move from Oklahoma to Tennessee through the day resulting in increasing cloud cover with time. The day should be mainly dry however by very late day, the leading edge of some light rain could begin moving into the Delmarva as well as SE PA and southern NJ. Monday's highs will once again be mainly in the 50s.

The initial wave of low pressure described above looks to spread some rain into the area Monday night into Tuesday with some snow at the onset possible over the southern Poconos. Following this initial wave, there looks to be a lull for a time Tuesday night into early Wednesday as the low re-organizes to our south in response to a stronger shortwave rounding the base of the deepening long wave trough over the east. This looks to eventually drive the low northward through the area late Wednesday into early Thursday as the system deepens. While it's a little early to get into any specifics, this part of the system could be more significant possibly bringing a period of heavier rainfall through the region. Since the low looks to track close to the area with no real cold air in place ahead of it, it should again be mainly rain area wide. Colder, drier weather looks to return by the end of next week in the system's wake with some possible snow showers around, mainly over the southern Poconos.

AVIATION /00Z SATURDAY THROUGH WEDNESDAY/. The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.

Tonight . VFR under a clear sky. Westerly wind around 5 knots or less. High confidence.

Saturday . VFR under a clear sky. West southwest wind increasing around 10 knots with gusts of 15 to 20 knots. High confidence.

Outlook .

Saturday night . VFR. Southwest to west wind less than 10 kts. High confidence.

Sunday . VFR. Southwest wind 5 to 10 knots. High confidence.

Sunday night . VFR. Southwest wind 6 knots or less, becoming south toward morning. High confidence.

Monday . Mainly VFR. Increasing cloud cover through the day with a slight chance of rain late in the day. S/SW wind 5 to 10 knots. Medium confidence on timing of any rainfall.

Monday night . MVFR likely. A chance of rain. South wind 5 to 10 knots. Medium confidence on timing and coverage of any rainfall.

Tuesday . MVFR with periods of IFR possible in rain. Southeast wind 5 to 10 knots. Medium confidence.

Tuesday night through Wednesday . Periods of Sub VFR conditions likely. There could be a lull in the rain though for Tuesday night before additional rain moves in for Wednesday. Winds light and variable Tuesday night becoming east 5-10 knots Wednesday.

MARINE. The north wind will continue to diminish into this evening and wave heights will subside. The Small Craft Advisory will be allowed to expire at 4:00 PM for the remaining waters off New Jersey. After further consideration, the Small Craft Advisory will be extended until 7:00 PM for the waters off Delaware to allow wave heights a little extra time to fall below 5 feet.

A westerly wind near 10 knots overnight should increase around 15 knots for Saturday. Wave heights on our ocean waters will favor the 2 to 3 foot range. Waves on Delaware Bay should be 2 feet or less.

Outlook .

Saturday night . Sub-SCA conditions expected with seas generally running 2-3 ft and gusts up to 20 kts.

Sunday through Monday . Sub-SCA conditions expected with seas generally running 2-3 ft and gusts of 10 to 15 kts.

Monday night and Tuesday night . Sub-SCA conditions expected with seas increasing to 3-4 ft and gusts mainly 15 kts or less.

Wednesday and Wednesday night . SCA conditions likely by Wednesday night with southeast winds increasing to 10 to 20kts and seas ramping up to 4 to 6 feet by Wednesday evening.

PHI WATCHES/WARNINGS/ADVISORIES. PA . None. NJ . None. DE . None. MD . None. MARINE . Small Craft Advisory until 7 PM EST this evening for ANZ454- 455.

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.
