SYNOPSIS. High pressure will briefly attempt to build southward today as the earlier front shifts further away from our region. A weak cold front is forecast to pass through our region Sunday night with another cold front slowly moving through the area Monday into Tuesday. High pressure will then build into our area Wednesday into Thursday before shifting offshore late in the week.

NEAR TERM /THROUGH TONIGHT/. Low pressure centered off the coasts of Virginia and North Carolina this morning will continue to slide farther out to sea. High pressure extending from the water off Nova Scotia to New England is forecast to build southwestward and into our region today and tonight.

A long wave mid level trough will remain over eastern Canada. A short wave dropping into the trough will continue to pass over New England this morning, then out to sea this afternoon. The feature will help to enhance the push of dry air into our region. However, a layer of moisture is anticipated to linger around 4000 to 6000 feet above the surface for much of the day. There should be a fair amount of stratocumulus this morning, with the dry air eventually causing the clouds to thin and scatter as the afternoon progresses.

Today's high temperatures are forecast to be mainly in the 70s. A northeast wind around 5 to 10 MPH is expected to veer to the east, then to the southeast.

An impulse traveling in the northwesterly mid level flow may trigger some showers from late today into tonight, mainly in Berks County, the Lehigh Valley and the Poconos. Any rainfall should be light.

Temperatures are expected to drop mostly into the upper 50s and lower 60s tonight with a light and variable wind.

Only made some minor adjustments to the forecast based on current observations and trends.

SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/. Synoptic Overview: The four corners ridge will amplify over the intermountain west over the short-term period, while conversely over the northeastern US, Canadian troughing will begin to establish itself. A low amplitude convectively-enhanced shortwave will pass through region late Sunday before a more substantial shortwave pivots into the area late Monday into Tuesday. At the surface, a weak cold front/prefrontal trough will approach the area on Sunday, however this feature should largely wash out near or over our area. A stronger front will approach the area late Monday, however there are indications this front will stall for a time near our area, and not really push through until Tuesday

Details: The main sensible weather concerns will be convection & precipitation chances, which look at least mentionable through more or less the entire period (although it will certainly not be raining the entire time). The diurnal timing for the Sunday system does not currently look favorable for strong-severe convection except perhaps for far western portions of our forecast area. For the remainder of the area expect scattered- numerous showers with maybe a few rumbles of thunder Sunday evening/night as the mid-lvl wave passes. Although the convective parameter space is reasonably impressive on Monday (MLCAPE around 1000 J/kg, bulk shear values around 40kts), there is considerable uncertainty with how far east the prefrontal trough makes it during peak heating. There seems to be growing consensus that low pressure will develop along the boundary to our south, which leads me to think the boundary will likely slow its eastward progress . and potentially not reach our area until the mid-lvl wave moves in Monday night into Tuesday. If that scenario materializes, any severe concerns would be once again limited to our far western areas (if that) . but it does still bear watching.

LONG TERM /TUESDAY THROUGH FRIDAY/. The general synoptic configuration of the Intermountain ridge/Northeast trough will hold through most of the extended, before perhaps becoming a bit less amplified and more progressive heading into next weekend. At the surface, once the cold front clears the area on Tuesday, dry west-northwest flow will prevail through the middle of the week as High Pressure to our west sags southeast. By late week, the High looks to move offshore with a northern-stream low approaching by next weekend.

In terms of details, Tuesday looks like the only day through Friday with mentionable precipitation chances, as the cold front only slowly moves out of the area and a couple mid-lvl waves pivot into our area around the base of the longwave trough. Drier air then filters in for Wed/Thursday and it should feel fairly pleasant with Highs only in the upper 70s/lower 80s and dewpoints only in the 40s and low 50s. Southerly return flow behind the departing High on Friday should warm us back into to the upper 80s, but think that any precipitation chances associated with the next system hold off until the weekend.

AVIATION /14Z SATURDAY THROUGH WEDNESDAY/. The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.

Today . Mainly VFR ceilings in the 4000 to 6000 foot range, though some few or scattered decks around 1500 to 2000 feet may remain through 16Z. The clouds may go scattered for a time late in the day. Northeast wind 5 to 10 knots, becoming east then southeast. Medium confidence.

Tonight . Mainly VFR ceilings. A chance of showers around KRDG and KABE. Variable wind 5 knots or less. Medium confidence.

Outlook .

Sunday and Sunday night . VFR much of the day on Sunday however the chance of restrictions in showers and thunderstorms will increase Sunday evening/night. Winds largely S-SW 5-10kts. Moderate confidence.

Monday and Tuesday . Predominantly VFR conditions are expected. However, brief MVFR or even IFR conditions are possible with showers and storms particularly Monday afternoon/evening. Westerly winds of 5 to 10 kts on Monday becoming northwesterly at 5 to 10 kt on Tuesday. Moderate confidence on the overall pattern, but low confidence on the timing and coverage of the showers and storms.

Tuesday night and Wednesday . VFR. NW winds around 5 knots Tuesday night becoming 5 to 10 knots Wednesday.

MARINE. As low pressure moves farther off the coasts of Virginia and North Carolina, high pressure is forecast to build over the coastal waters of New Jersey and Delaware from the north and northeast today and tonight.

A northeast to east wind 10 to 15 knots today, is anticipated to become east to southeast around 10 knots tonight.

Wave heights on our ocean waters should be around 3 to 4 feet. They could approach 5 feet at times today in the waters off Delaware, especially beyond 10 NM offshore. However, any 5 foot waves that develop are not expected to be widespread or prolonged enough to warrant a Small Craft Advisory. Waves on Delaware Bay should be 2 feet or less.

Outlook .

Sunday through Wednesday . Winds and seas should stay below SCA criteria through this period. There will be a chance of showers and thunderstorms over the waters starting Sunday night, with periodic showers/storms possible through Tuesday.

Rip Currents .

There is a MODERATE risk for the development of dangerous rip currents along the coasts of New Jersey and Delaware today due to the continued northeast to east wind. Breaking waves should be mostly in the 2 to 3 foot range.

The wind direction should become east to southeast for Sunday. The onshore flow will again result in a MODERATE risk for the development of dangerous rip currents with breaking waves around 2 feet.
