SYNOPSIS. A weak cold front will move across the east coast today. High pressure will build across the Mid Atlantic and northeast states Saturday and Saturday night, before shifting offshore on Sunday. A warm front is expected to lift northward across the area on Monday, followed by a cold front Tuesday into Tuesday night. High pressure builds back across the Mid Atlantic region Thursday into Thursday night, before shifting offshore through Friday.
NEAR TERM /UNTIL 6 PM THIS EVENING/. Potent trough that brought some lake-effect precipitation all the way to the northern CWA on Thursday is finally moving off the coast early this morning. Descent on the upstream side along with nocturnal decoupling (aided by an approaching surface ridge) has aided in the dissipation of lower clouds, with temperatures falling quickly the past few hours. However, the lower clouds will return this morning as the next northwest-flow shortwave trough digs southeastward into the Northeast. An attendant surface low will migrate eastward through New York today, with a southwestward- extending cold front approaching the area this afternoon. Though this system is fairly moisture- starved, do expect a few showers to develop along and in advance of the front today via fairly stout large-scale lift. Best chances look to be during the afternoon. Precipitation amounts will be quite light, and temperatures will be warm enough for rain, except possibly the Poconos and vicinity.
With warm advection in advance of the approaching system, temperatures should be a little warmer today, though this will be tempered by increasing/lowering cloud cover. Generally have max temps about 5 degrees warmer than Thursday's values. Winds will diurnally swing upward this afternoon, aided by an increasing surface pressure gradient as the low to our north makes its closest approach to the CWA. A few gusts of 20 to 25 mph or so can be expected this afternoon.
SHORT TERM /6 PM THIS EVENING THROUGH 6 AM SATURDAY/. The aforementioned cold front will move through the area this evening, switching winds to northwest (perhaps gusting for a bit around the time of frontal passage). Showers (scattered and light in nature) may occur near the time of frontal passage, with best chances along/southeast of the urban corridor given anticipated location of the front. The front should move offshore around/after 06z with skies rapidly clearing upstream. Though winds should diminish somewhat overnight, they will probably remain elevated enough to prevent ideal radiational cooling conditions. As such, kept temperatures fairly close to consensus and continuity, which are not too different than the readings being observed this morning.
LONG TERM /SATURDAY THROUGH THURSDAY/. Quiet weather begins the long term period over the weekend, then unsettled weather returns for the beginning of next week, then quiet weather returns for the end of next week.
High pressure builds across the area later in the day Saturday then centers itself across the region Saturday night, before shifting offshore on Sunday. This will keep dry weather in the forecast Saturday through Sunday. Winds may be a little gusty at times Saturday morning, as well as during the day Sunday, but gusts should remain mostly 15 to 20 mph, with occasional high peak gusts around 25 mph.
As we move into Sunday night, a warm front is expected to be lifting north toward the area, then lift across and through the area during the day Monday. At the same time, there will be multiple short wave/vorticity impulses moving across the area starting late Sunday night and continuing through Monday night, even once the warm front lifts through the area. With enhanced moisture across the area, this is expected to lead to several possible periods of enhanced rainfall chances across the area through Monday night. If any precipitation starts early enough Sunday night while temperatures a cold enough, a brief wintry mix may be possible for portions of northeast Pennsylvania and northern New Jersey before changing to all rain.
Then as we move into Tuesday, a cold front is expected to move across the area later during the day into the evening. This will lead to another period of enhanced rainfall chances, especially during the afternoon and evening. PW values will likely exceed 1.00 inches and approach 1.25-1.50 inches Monday-Tuesday, so there could be period of moderate to heavy rainfall at times.
The cold front will have moved offshore by Wednesday morning, then our area will be under the influence of strong northwest flow. Wind gusts are expected to increase to at least 20 to 30 mph with occasional higher gusts around 35 mph possible. Lake effect snow showers will likely be ongoing through the day to our north across New York and northern Pennsylvania where the steepest lapse rates and enhanced moisture will be located. The low-mid level flow will likely keep the showers to our north, but there is still a slight chance if the flow turns a little more south some lake effect showers could make it down into our area.
The chance for showers cuts off by Thursday as high pressure builds across the area, so dry weather is expected for Thursday into Thursday night.
AVIATION /09Z FRIDAY THROUGH TUESDAY/. The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.
Rest of tonight . VFR with mid/high cloudiness increasing. Winds light west or southwest. High confidence.
Friday . Mainly VFR with a lengthy period of CIGs around 5000 feet. Cannot rule out a passing shower during the day, but any impacts would be minimal. Winds west or southwest around 10 kt with perhaps a few gusts to 20 kt or so. Moderate confidence.
Friday night . VFR with any CIGs rapidly dissipating overnight. Northwest winds 5 to 10 kt, perhaps a little stronger in the evening. High confidence.
Outlook .
Saturday-Sunday . VFR conditions expected. Northwest winds Saturday shift to the northeast Saturday night, then southeast and south on Sunday. Winds may gust around 15-20 knots at times Saturday and Sunday. --High confidence.
Sunday night . Conditions may lower to MVFR later in the overnight ahead of a lifting warm front. South winds may shift to southeast late in the night. --Moderate confidence.
Monday-Tuesday . An extended period of MVFR and IFR conditions likely as periods of rain move across the area. Southeast winds early Monday become southwest once a warm front lifts across the area Monday. Winds shift to the northwest behind a cold front later Tuesday into Tuesday night. --Moderate confidence.
MARINE. Have allowed the small craft advisory for the Atlantic waters to expire early this morning, but this will be short-lived. After a lull in winds that should last much of the morning, expecting south to southwest winds to increase rapidly around midday, with advisory conditions expected to return on the Atlantic waters this afternoon. It is not out of the question that gales are observed, but the regime is not climatologically favorable for gales (harder to reach in pre-frontal southwest flow versus post-frontal northwest flow) and model soundings are fairly marginal both in terms of magnitudes of gusts and duration. As a result, issued another small craft advisory beginning at noon today. A cold front will move through the waters this evening/tonight, switching winds to northwest. This may be the best timing for a few gusts to reach marginal gales, but confidence is too low to issue a warning at this time. Winds should diminish slowly late in the night, so the advisory expiration time is 6 am Saturday.
For Delaware Bay, expecting mostly sub-advisory winds today (though a few gusts to 25 kt or so may occur this afternoon). However, as the front moves through this evening, expecting a few hours of marginal advisory conditions with the switch to northwest wind directions and favorable channeling effects. Therefore, issued a small craft advisory for lower Delaware Bay from 9 pm this evening to 6 am Saturday.
Seas may approach 5 feet late this afternoon into this evening near the time of frontal passage.
Cannot rule out a few showers near the front late this afternoon into this evening. These showers may be accompanied by stronger/erratic gusts.
OUTLOOK .
Saturday-Sunday night . Conditions are expected to be below Small Craft Advisory levels.
Monday-Tuesday . Small Craft Advisory conditions likely as winds and seas increase as a warm front lifts across the area Monday, then a cold front moves across the area Tuesday.
PHI WATCHES/WARNINGS/ADVISORIES. PA . None. NJ . None. DE . None. MD . None. MARINE . Small Craft Advisory from noon today to 6 AM EST Saturday for ANZ450>455. Small Craft Advisory from 9 PM this evening to 6 AM EST Saturday for ANZ431.
