SYNOPSIS
An upper-level high pressure ridge will build along the East coast, with unseasonably warm temperatures expected Monday.
A backdoor cold front will then arrive Monday night and hang across our region on Tuesday, while an upper-level trough approaches. Showers and thunderstorms may threaten later Tuesday and possibly linger into Wednesday, before weak high pressure builds in for Thursday. A cold front could approach from the west later Friday and pass through during the weekend.

NEAR TERM /THROUGH MONDAY/
A warm spring afternoon is underway with a warm advection regime in place across the region along with building upper ridging. The morning stratus has mixed out and the sea breeze is beginning to move inland from the coast. Some diurnal cumulus will likely develop before dusk, otherwise some scattered cirrus will persist.
Temperature should peak near 80 degrees in most areas.

A weak shortwave trough will round the top of the ridge into this evening, passing from the eastern Great Lakes into Upstate New York.
CAMs continue to indicate that this feature will initiate some isolated to scattered showers and a few storms within the 5-10 PM time frame, most likely impacting areas north and east of a line from Allentown to Trenton. Instability are forcing are fairly weak, although shear is modest near 30-40 kts. This activity is unlikely to be severe, but cannot rule out some gusty winds or small hail with the activity through the evening. Lows tonight will be about 10- 15 degrees above normal, mainly in the mid 50s to near 60 degrees with clearing skies behind any convection.

The main story heading into early next week will be the strengthening ridge across the East Coast. 500 mb heights look to increase to near 580 dam by Monday, values more typical of summertime. At the surface, high pressure will remain centered offshore of the Carolinas, helping to advect warmer and more moist air into the region. The result will be much above normal temperatures. Monday will be the warmest day of the stretch and likely the warmest day so far this year, with high temperatures soaring into the mid to upper 80s in most interior locations under partly cloudy skies. Highs in the more urbanized areas could top out closer to 90 degrees, though readings of 90 degrees or higher appear unlikely at this time. The northwest flow will add a downsloping component to the winds and thus also help to boost temperatures locally near the urban corridor. The offshore wind will also allow for a notable warmup even along the immediate coast, with highs getting to the low to mid 70s before the sea breeze kicks in.

As the gradient flow weakens and shifts eventually to the southwest then south, the sea breeze will likely make significant inland progress into the I-95 corridor and perhaps even farther inland from there during the evening. This will cool temperatures off into the 70s and 60s by late evening. Dewpoints will be near 60 degrees, so the Heat Index won't be much different than the air temperature on Monday. No heat headlines are anticipated. With some additional weak wave rounding the top of the ridge, some isolated showers or storm are possible north of Philly, however the subsidence will be quite strong and any convection will likely struggle to materialize.

SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY/
Beginning on Monday evening, we may see a few lingering shower mainly across northern New Jersey, perhaps extending down to northern portions of the shore, but those will likely dissipate quickly after sunset with very weak synoptic-scale forcing and a mid/upper-level ridge axis aloft. Otherwise expect a mainly dry and quiet night. Low temperatures will be quite mild across much of our region, with many areas south and west of about Trenton forecast to stay above 60F, which would be the mildest night since last October. The exception, with lows into the lower 50s, will be toward the northern NJ shore. Surface high pressure presses southward across New England and sends a shallow backdoor cold front into the northeast corner of our area. That can be seen in the wind fields of the latest hi- resolution models.

While that ridge axis will start to give way to an approaching upper-level trough Monday night into Tuesday, shifting off the East Coast, mid-level temperatures will only lower slightly.
That warm air aloft will not manifest at the surface for northeast portions of our region, though, thanks to that back- door front. Models disagree on how far south that cooler airmass will seep, but expect most of the shore to stay in the 60s with east to southeast winds off the still chilly Atlantic waters.
Water temperatures are still mainly in the low to mid 50s. As the warmer air aloft overrides that cooler airmass, low clouds will develop late Monday night and may reach as far south as near Philly to Brigantine NJ early Tuesday morning. Some of those clouds should lift out heading toward the afternoon, especially away from the shore, but will still keep temperatures much cooler than Monday. For now we are still forecasting low 80s in Philly, but it will be a tricky forecast. Expect most areas northeast of there to struggle to reach higher than the low to mid 70s, with some model guidance suggesting parts of northern NJ to the Poconos will stay mostly cloudy and in the 60s on Tuesday.

Aside from the temperatures Tuesday, we will have to keep an eye out for showers and thunderstorms developing across central and eastern PA ahead of the approaching upper-level trough. The southern stream portion of the trough will split and hang back across the Tennessee Valley, with the northern stream shortwave tending to 'pull-up' and weaken as it approaches. Additionally, a new surface low will develop around SE PA into northern Delaware on Tuesday, before tracking ENE offshore Tuesday night.
All of this will tend to limit instability and forcing from the Delaware Valley eastward across NJ, so that storms will eventually weaken as they head into that airmass. That said, guidance does indicate 1000-2000 j/kg of CAPE and perhaps 30-35 kt of deep layer shear, so that while the absence of a distinct surface cold front and weaker forcing aloft may limit thunderstorm potential, anything that does develop across eastern PA could be rather strong, even locally severe, before it weakens. Do not expect widespread storms though, with fairly limited rainfall area-wide Tuesday afternoon and evening.

Even on Wednesday, as low pressure pushes offshore, a fairly moist atmosphere will remain in place, while some model guidance slows the upper-level trough passage enough so that it will not pass by portions of our area until the afternoon. That may allow a few spotty showers to linger, along with a fair amount of cloud-cover. Lowered high temperatures a bit from NBM guidance otherwise area-wide, as much of our region will be more exposed to cooler east-northeast flow, keeping highs mainly in the low to mid 70s from the Delaware Valley west, and in the 60s toward the shore.

LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/
High pressure will take control heading into the last couple days of the work-week. While upper-level ridging will start to shift eastward across the Appalachians toward Friday, another surface high pressing southward from New England may bring another 'back-door' shot of cooler air in, keeping at least much of the shore and perhaps much of northern NJ in the 60s to low 70s. Dry weather is expected with fairly plentiful sunshine, and slightly above normal temperatures farther southwest from the marine influence. Some showers may threaten as early as late in the day Friday, with increasing clouds toward eastern PA, as the next storm system approaches. That looks to be another surface low lifting across the Great Lakes, with a weakening surface cold front heading our way over the weekend. Stayed with NBM POPs. Not looking like a washout, but some scattered showers and possibly some thunderstorms possible. Temperatures should remain pretty close to typical values for early May, if not slightly above normal.

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

Rest of today...VFR conditions with scattered clouds. Winds mainly from the southwest near 5-10 kts. Some scattered SHRA/TSRA possible at ABE/TTN after 21Z. Included VCSH to highlight this for now, although cannot rule out some thunder possible through 03Z or so.
High confidence on prevailing conditions.

Tonight...VFR with some scattered clouds possible. Winds mainly 5 kts or less favoring a southwest direction initially, then shifting northwest overnight. Some isolated SHRA/TSRA possible through 03-06Z at ABE/TTN. High confidence in prevailing conditions.

Monday...VFR conditions with scattered clouds. Winds initially from the northwest near 5-10 kts will shift to to southwest or even south after 18Z. A 10-20% chance of an isolated shower. High confidence in prevailing conditions.

Outlook...

Tuesday and Wednesday...Mainly VFR but occasional MVFR and even briefly/locally IFR conditions possible in scattered showers and thunderstorms later Tuesday afternoon and evening. Some of those showers may linger into Wednesday.

Thursday and Friday...VFR conditions expected.

MARINE
No marine headlines anticipated through tonight. South to southwest winds through this evening near 10-15 kts will shift briefly toward the northwest early Monday morning due to a land breeze. Winds shift back to the south by late morning. Seas 2-3 feet. A 20-30% chance of a shower or thunderstorm tonight north of Atlantic City.

Outlook...

South to southeast winds may pick up to near 15 kt off the southern NJ and Delaware coast enough to raise seas above 4 ft.
Some scattered showers and even a stray thunderstorm will threaten by Tuesday evening and may linger into Wednesday.
Winds will tend more E to NE on Wednesday but still just around 10 kt or so, with seas near 3 ft. Expect very similar conditions for Thursday as high pressure builds southward from New England for the end of the work-week, with winds tending more southerly by Friday. Small Craft Advisory conditions are not anticipated through the week ahead.
