Area Forecast Discussion National Weather Service Mount Holly NJ 541 PM EDT Sat Jun 21 2025
SYNOPSIS
Hot and dry high pressure across the western Atlantic will build west into the Appalachian region early next week. This will result in a significant heat wave for much of the eastern US with near record breaking temperatures forecast. The high pressure system will begin to weaken and retreat to the south by the middle to end of the week, and temperatures will return closer to normal along with increasing chances for showers and storms.
NEAR TERM /THROUGH SUNDAY/
A multi-day dangerous heat event begins Sunday.
The center of a strong upper-level ridge positioned across the Ohio and Tennessee Valleys will start to expand northeastward some late tonight and especially during Sunday. As this occurs, surface high pressure will build westward from the far western Atlantic. This will all direct a hotter and more humid air mass across our area through Sunday night. A very isolated shower or thunderstorm is possible this afternoon well north and west of the I-95 corridor given ample instability but rather weak forcing. Some higher dew points pooling near the lower Susquehanna Valley has popped a few showers already, and the terrain influence from northeast Pennsylvania to northern New Jersey could assist in the development of a few isolated cells. Any of this is expected to dissipate through early this evening. Otherwise, some cirrus from upstream convection continues to dive southeastward across our area. A sea breeze is making slow inland progress this afternoon especially across eastern New Jersey.
A shortwave trough however is forecast to slide across New England later tonight and Sunday morning. Shortwave energy associated with this along with some convectively enhanced energy will drive one or more convection clusters around the northern periphery of the building ridge. The guidance has generally been settling in on a solution that keeps the convection mainly to our north through Sunday. However, there are signals in some of the guidance as the convection moves across parts of New England a trailing outflow may settle into portions of our region from the north. There is a low potential that some renewed convection occurs along this lingering boundary during the day Sunday. This is very low confidence at this time as much of the guidance is dry. We will need to watch this potential though and also if some storms can initiate over the terrain in the Pocono region and then dive southward. Given all of this, opted to keep the forecast dry on Sunday.
Sunday is the start of a multi-day dangerous heat event, with high temperatures rising into the mid 90s (some upper 90s) across much of the area. The dew points will also increase into the upper 60s to low 70s, although these could mix out a little during peak heating especially across the coastal plain. Heat indices to around 100 degrees are expected for nearly the entire region, with these a little lower in the higher elevations and closest to the coast. As a result, the Extreme Heat Warning and Heat Advisory both begin Sunday morning. For far southern New Jersey and most of our Delmarva zones, the criteria here is higher and therefore continued to not include them in a heat related headline for Sunday. A stronger breeze develops on Sunday, although given ample heating over land the wind direction may stay more southwest or south-southwest for the coastal areas keeping the New Jersey beaches especially cooler than a few miles inland.
It will be very warm and muggy Sunday night as dew points rise some and low temperatures drop only into the 70s. It may struggle to drop below 80 degrees in the highly urbanized centers.
SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY NIGHT/
Significant heat wave peaking Monday and Tuesday with dangerously hot and humid conditions expected.
A strong ridge of high hot and dry pressure will build across the eastern US Monday and Tuesday. Mid level heights, thicknesses, and 850 mb temperatures contributing to the heat wave will all peak during this time frame. The center of the ridge will be positioned to our southwest, which should maximize heat potential locally. At the surface, winds will be modest from the west or northwest. This will add a component of downsloping into the temperature equation, helping to boost temperatures by a couple degrees. The wind direction will also lessen the influence of the sea breeze, or lack thereof, for coastal areas. The pattern is checking a lot of boxes for a set up capable of producing fairly widespread 100 degree temperatures in our region, perhaps one of the most favorable patterns in a few years.
Fortunately, the pattern will favor dewpoints mixing out reasonably well into the afternoon hours, but the high temperatures will still result in heat indices of around 100-110 degrees across the board both Monday and Tuesday. At this point, Monday looks to be the most humid of the 2 days, and thus highest heat index day with heat indices around 105-110 degrees in many areas. Slightly drier air, slightly stronger northwest flow, and perhaps deeper mixing on Tuesday will favor slightly higher temperatures, but heat indices should be near or perhaps a few degrees lower than Monday. Regardless of those details, it's going to be very hot both days!
Extreme Heat Warnings and Heat Advisories remain in effect as previously issued. Around the Delaware Valley, Lehigh Valley, and northern New Jersey, temperatures could be the hottest observed in over a decade. There will be little relief overnight as temperatures Monday night and Tuesday Night are expected to be around 75 to 80 degrees. Heat tends to have cumulative effects on the body and we are currently forecasting 4 consecutive days of 95+ with Monday and Tuesday likely to feature high temperatures around 100 degrees and heat index values pushing 105-110 degrees. Take frequent breaks if outside, and drink plenty of fluids. Not much else to say to highlight the threat and main story of the upcoming week.
For details regarding the last 100 degree day and temperature records during the upcoming heat wave, see the Climate section below.
LONG TERM /WEDNESDAY THROUGH SATURDAY/
For Wednesday and Thursday...The upper-level ridge weakens a little bit and flattens out/erodes, especially on the northern periphery. While the heat and humidity looks to continue, it should decrease at least some by Wednesday, and especially Thursday and Friday with continued erosion of the northern side of the ridge. In addition, a surface trough should become better defined and introduce a bit more clouds and also the potential for at least some diurnally driven convection. There is a cold front that tries to slide southward on Wednesday, but there is a decent amount of uncertainty with how far south the cold front makes it given the strength of the ridge. Due to this front, there is a slight chance to chance (15-30%) of showers and thunderstorms late Wednesday from the Philadelphia metro on north and west. Increased cloud cover will keep temperatures a touch cooler on Wednesday, but the Extreme Heat Warning remains in for northern Delaware, the Philadelphia metro, Lehigh Valley, and central/northern NJ. Temperatures will be a few degrees cooler compared to Monday/Tuesday, but still in the mid to upper 90s, marking the 4th consecutive day of highs greater than 95 degrees. Heat indices will be near 100 degrees on Wednesday too, so a slight improvement, but still hot.
As mentioned above, the ridge erodes a bit towards the end of the week with a signal for some troughing building in from the north that could lead to showers and thunderstorms both days to end the week. The temperatures look to still hold near 90 degrees on Thursday and in the 80s by Friday, with heat indices still in the 90s but this will be lower than earlier in the week.
AVIATION /22Z SATURDAY THROUGH THURSDAY/
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.
This afternoon...VFR. Southwesterly winds 5-10 knots. An isolated shower or thunderstorm possible well north and west of KPHL.
Moderate confidence.
Tonight...VFR. Southwest winds less than 10 knots, becoming light and variable at some terminals. Moderate confidence.
Sunday...VFR. Light and variable winds becoming west to west- southwest 5-10 knots in the morning then 10-15 knots with some gusts up to 20 knots in the afternoon. The winds then diminish in the evening. Moderate confidence.
Outlook...
Monday through Tuesday Night...VFR. No significant weather.
Wednesday and Thursday...Prevailing VFR, though chances of a shower/thunderstorm (20-40%) for the I-95 and Lehigh Valley terminals, especially Thursday.
MARINE
The conditions are expected to remain below Small Craft Advisory criteria through Sunday night, despite southwesterly winds increasing some tonight and Sunday.
Outlook...
Monday through Thursday...No marine headlines expected. Winds 5-15 kts and seas 1-2 feet. Fair weather, but chances for thunderstorms return by Thursday.
Rip Currents...
On Sunday, SW winds increase to 10 to mph with breaking waves of 2 to 3 feet. This will result in a MODERATE risk for the development of dangerous rip currents for the Jersey Shore counties of Ocean, Atlantic, and Cape May. For the Jersey Shore county of Monmouth, as well as Delaware Beaches, flow will be a bit more offshore, resulting in a LOW risk for the development of dangerous rip currents.
For Monday, W to NW winds of 5 to 10 mph will turn S in the afternoon behind developing sea breezes. Since winds will be fairly light, there will be a LOW risk for the development of dangerous and life threatening rip currents for the Jersey Shore and for Delaware Beaches.
