SYNOPSIS
High pressure at the surface becomes centered offshore of New England through tonight and then gradually shifts southeastward through this week. A warm front lifts across our area on Monday, and with building high pressure aloft all of this week will result in a prolonged stretch of increasingly hot and dry conditions.

NEAR TERM /THROUGH MONDAY/
Surface 1027 mb high pressure over New England this afternoon will migrate eastward to be just offshore by this evening.
Though we will still feel the influence of the surface high offshore through tonight, a warm front from the southwest will lift northwards and approach with time. This warm front is posed to cross through our region sometime Monday morning.

A dry forecast with quiet conditions is on tap for the near term.
Though the warm front will approach with time tonight, no precipitation is expected thanks to the strength and proximity of the surface high.

A building 500mb ridge across the Southeast U.S. will continue to expand north through the Mid Altantic on Monday. Maximum temperatures on Monday will be in the 80s to around 90 with dewpoints in the lower 60s.

SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY NIGHT/
Excessive heat is expected to start building during this period.

A building 500 mb ridge across the Southeast U.S. will continue to expand north through the Mid-Altantic through Wednesday as surface high pressure shifts more offshore. As the warm air advection increases, the heat will build with highs Tuesday and Wednesday into the low to mid 90s for much of the area.

As the ridge builds, subsidence starts to become enhanced and temperatures at the surface will therefore be hot. The placement of the ridge aloft though and surface high pressure offshore but lighter southerly flow does not favor much in the way of increasing low-level moisture. This is seen in the dew point forecasts from several of the models, which show dew point values on the lower side Tuesday especially. Due to ample heating of the boundary layer and a continued drying of the top layer of the soil tends to result in lowered dew points especially during peak heating. Therefore, the heat indices forecast for Tuesday afternoon and Wednesday afternoon are lower than previously forecast. There also looks to be some slower development in the building heat with at least some guidance a little cooler both days. There should be some moisture recovery Wednesday however even then some lowering of the dew points during peak heating should occur given the significant heating of the boundary layer. The southerly flow will continue and it will be on the light side and therefore sea and bay breeze circulations are expected. This will provide cooling closer to the coast, although it is possible that these make their way well inland by later afternoon or early evening.

This heat will be several consecutive days and factoring in more of the impacts and not solely on the heat index criteria values, Heat Risk for Pennsylvania and inland New Jersey is forecast to increase to moderate with portions of the I-95 corridor increasing to Major.
The concern with the heat is that the temperatures will be building throughout the week and externally, this is early in the season for an extended heat event with increasing numbers of vulnerable communities/events due to school years ending and a federal holiday in the middle of the week. Despite some lowering of the temperatures and dew points, some high temperature records Tuesday may be challenged Tuesday. We continued the Heat Advisory for the I-95 corridor to the north and west, especially as the urban corridor from Wilmington to Philadelphia to Trenton has a slightly lower heat index criteria for an advisory (96 degrees). Wednesday may also not be quite as hot given the ridge still building, however the highest heat looks more likely once we get into the long term portion below.
Given that this is a multi-day heat event and while heat index warning criteria may not occur, opted to go with an Excessive Heat Watch starting Wednesday for the same areas of the Heat Advisory based on increasing impacts (increasing Heat Risk categories) from a prolonged excessive heat event. The initial core of the heat looks to start across our northern to central areas before eventually sliding southward some later in the week, therefore no heat related headlines farther south at this time.

LONG TERM /THURSDAY THROUGH SUNDAY/
Summary...Excessive heat probable with little to no rain chances.

The model guidance continues to show that the upper air pattern supports an extended period of heat across much of the area (high temperatures in the 90s). There's been almost no change to the forecast of an expansive and deep-layer ridge that will be centered across our region with additional warming expected through Friday.

With warm air advection in place during the early potion of the week and strengthening of the 500 mb high towards the end of the week, the latter half of the week is more likely to be the hottest. The heat dome will maintain surface high pressure to our east with the surface flow more out of the south. The southerly flow looks to be fairly light and the moisture advection is not much, and therefore surface dew points should not be crazy with this heat. In addition, many days of hot temperatures tends to lower the dew points some during peak heating and this can be enhanced some by a dry to drying ground. There will also be less relief at night as time goes on especially in the urban centers with lows dropping only into the 70s. The southerly flow however should keep the coastal areas noticeably cooler than inland, and if the flow is light enough especially under this ridge then a sea/bay breeze many days could get farther inland during the later afternoon hours. The ridge will feature plenty of dry air aloft which tends to limit cloud development and therefore rain especially given warm air aloft. As a result, convective chances are little to none.

While the model guidance does differ some on the timing and extent, the large ridge is forecast to start pushing southward some and elongates more west to east Friday through Sunday as a trough in south-central Canada starts to flatten the northern side of the ridge. The main concern for this event is that the multi-day heat tends to have more impacts especially in urban centers when combined with less relief at night. Heat Risk impacts show Major or higher impacts through next Sunday.

Confidence is high in widespread heat related impacts across the region through the week, however as we get into the weekend the ridge should be flattening some on the north side which lowers the heights some and also the temperatures aloft. However despite this, the potentially dangerous heat looks to continue and the Excessive Heat Watch runs through Saturday. There may also be some opportunity for a few showers or thunderstorms later in the weekend especially for our northern zones which will be closer to the Canadian trough.
Given the presence of the ridge though, PoPs are only in the 20-30 percent range mainly across the northern into the central parts of the region at this point.

AVIATION /20Z SUNDAY THROUGH FRIDAY/
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.

This afternoon...VFR. Winds becoming SE 5-10 kts. Moderate confidence.

Tonight...VFR. SE winds 5-10 kts becoming S overnight. High confidence.

Monday...VFR. S wind 10 to 15 knots. Moderate confidence.

Outlook...

Monday night through Friday...VFR with no significant weather.

MARINE
No marine headlines expected through Monday. SE winds 8-12 kts this afternoon, S winds 5-10 kts tonight, and S winds 10 to 20 knots Monday. Seas 2-4 feet.

Outlook...

Monday night through Friday...The conditions are anticipated to be below Small Craft Advisory criteria.

Rip Currents...

With lighter winds around 10 mph and lower waves of 2-3 feet this afternoon, there is a LOW risk for the development of dangerous rip currents for both the New Jersey Shore and Delaware beaches.

On Monday, winds will increase back to 10-15 mph but look to be out of the south. This wind direction would result in largely shore parallel winds except for the more south facing beaches in Cape May and Atlantic Counties. Additionally, waves in the surf zone are forecast to remain 2-3 feet with a short-medium period swell. Combining all these factors together, we are forecasting a LOW risk for the development of rip currents for now.
