SYNOPSIS. A weak cold front will move through the region tonight. Strong high pressure will be centered over the Southeast on Sunday and will shift offshore on Monday. A cold front will cross the region Tuesday as weak low pressure moves to our north. Upper level low pressure dropping southward into New England will then influence our weather for the rest of next week.

NEAR TERM /THROUGH SUNDAY/. An upper trough and sfc cold front will cruise across the forecast area this evening and for the early overnight hours. Little sensible weather expected with some transient high/mid level clouds. Weak low pressure will form offshore and move north, but much of the cloudiness with this feature will remain across the waters. A brief shower on the waters is possible. Later tonight, the front will move away and clouds will diminish. Lows tonight will be low 50s for the north/west most areas and mid 50s for metro Philly and Delmarva.

The cold front will be east of the region Sunday morning. A fair weather day is expected with mostly sunny skies and a noticeable breeze. High temperatures Sunday will be in the low to mid 70s with some upper 60s across the southern Poconos. Winds will increase from the NW by mid-morning and range 10 to 15 mph with some gusts around 20-22 mph at times. Winds will diminish towards sunset.

SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY/. Expansive surface high pressure centered over the Southeast on Sunday night will shift offshore on Monday. We remain along its northern periphery which will allow the current stretch of tranquil weather to continue into the new week. A fast-moving shortwave disturbance will pass north of the region late Sunday night, but no precipitation is expected locally with that. Lows in the low to mid 50s are forecast. Monday will be another beautiful day, and a little warmer with highs in the mid to upper 70s as southwest flow develops ahead of a cold front. Warm advection and continued southwest flow will keep lows Monday night several degrees warmer than prior nights.

That cold front will likely prove to be the only weather system of note for next week. Latest trends are faster with its approach, and the fastest guidance such as the NAM suggests it could start working through the region as soon as late Monday night. A consensus timing would bring it through more during the day on Tuesday. This front is expected to be progressive and is not especially strong, so it won't be a major event for our area. However, at least scattered shower activity is likely as it passes, as we briefly get into some better moisture return ahead of it. Showers are possible by late Monday night, mainly to the north and west, if the front is fast enough. For Tuesday, have basically included chc PoPs all day owing to uncertainty with the frontal timing, but it will certainly not be a washout. Did add a slgt chc of thunder, but this will be heavily contingent on the front moving through towards the peak heating hours. If that happens, fairly steep lapse rates could allow for a couple of stronger storms with gusty winds and small hail. High temperatures on Tuesday should run above normal for most of the region, unless the front moves through several hours faster and allows cooler air to start advecting in.

LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/. Overview .

If you like fall weather, next week is the week for you. Following the cold frontal passage on Tuesday, several days of near to slightly below seasonable temperatures and mainly dry weather are expected. The large scale pattern will be dominated by deep upper level low pressure over New England, which will slowly drift south- southeast through the week. Strong ridging will be present over the Great Lakes and Midwest. Despite the close proximity of the upper low, it is unlikely to be a problem for us, with a lack of moisture and forcing over the mid-Atlantic preventing rainfall. However, the low will serve to keep away the anomalously warm air associated with ridging to our west, which at least for the time being will prevent any resurgence of summer-like air.

Dailies .

Tuesday night . The cold front from during the day on Tuesday will push offshore overnight. While a lingering shower is possible, mainly early and to the southeast, the faster trends in timing suggest the night will probably be dry for most areas, especially further northwest. Advancing cooler air will help lows drop into the upper 40s and low 50s to the northwest, while lingering clouds and a later arrival of cooler air keep coastal areas closer to 60.

Wednesday-Friday . Tranquil weather overall. With the upper low to our north gradually dropping south and a few shortwaves rotating around it, we may see some diurnally driven enhanced cloud cover and maybe a spot shower or two at times. But that would be the exception. Daytime highs will range from the mid 60s to low 70s, with lows in the upper 40s and low 50s.

Next weekend . Uncertainty increases, as the upper low continues to drop south and possibly interacts with Hurricane Sam well offshore, creating a lower predictability pattern. While it is possible tranquil weather may continue, the period around next weekend will probably be a low predictability forecast for some time.

AVIATION /19Z SATURDAY THROUGH THURSDAY/. The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.

Tonight . VFR expected with mostly just sct-bkn high level cloudiness. Sct lower clouds possible along the NJ shore areas possibly backing into KACY. SW to W winds mostly around 5 kts.

Sunday . VFR expected. NW winds 10 to 15 knots with gusts 20 to 25 knots developing after 12Z/13Z. Few clouds expected.

Outlook .

Sunday night . VFR. Winds light and variable or light southwesterly. High confidence.

Monday-Monday night . VFR. Southwest wind 5 to 10 kt with some gusts near 20 kt Monday afternoon, decreasing overnight. High confidence.

Tuesday-Tuesday night . Mainly VFR. However, scattered showers with a slight chance of a thunderstorm could bring localized restrictions. West-southwest wind gradually shifting to northwest with speeds less than 10 kt. Moderate confidence.

Wednesday-Thursday . VFR. Winds mainly from the north or north- northwest at 5 to 10 kt. High confidence.

MARINE. Winds are rather gentle on the waters today with speeds mostly under 10 knots. Seas on the ocean have been around 3 ft with 1 to 2 ft on Delaware Bay. A front remain well out to sea and with weak low pressure moving along it, some extra cloudiness is being observed for the waters. Most of any shower activity will well to the east attm. Overnight, a cold front will cross the waters and while no showers are expected, a wind shift will occur and speeds will become gusty tomorrow morning. We have issued a SCA flag for the northern two NJ coastal water zones for Sunday. Gusts around 25 knots and 5 ft seas are possible. Winds and seas will decrease by sunset Sunday.

Outlook .

Sunday night-Thursday . Mainly sub-SCA conditions are expected with seas 3 to 4 ft. Southwest winds late Monday and Monday night may gust close to 25 kt. Showers and tstms possible Tuesday with a cold front, which will shift winds from southwest to north-northeast over the waters. By Thursday, seas on the Atlantic coastal waters may approach 5 ft.

Rip currents .

Surface winds will be variable along the coast today. More onshore across northern NJ and more offshore across southern NJ and DE. Winds will be offshore everywhere on Sunday. Being light and/or mainly offshore, this will help to keep the rip current risk slightly lower than what we have seen the last few days. However, we still expect to see a moderate risk through the weekend.

PHI WATCHES/WARNINGS/ADVISORIES. PA . None. NJ . None. DE . None. MD . None. MARINE . Small Craft Advisory from 6 AM to 6 PM EDT Sunday for ANZ450- 451.
