NWS Philadelphia/Mount Holly wrote its last area forecast discussion before the first event at Jul 24, 5:42 AM EST, 3 hours 53 minutes earlier.
Area Forecast Discussion National Weather Service Mount Holly NJ 642 AM EDT Fri Jul 24 2020 .SYNOPSIS... A weak cold front will slowly sink southward through the region today. The front will finally sink to our south by Saturday as high pressure builds in from the north and remains over us through Monday. A cold front will approach on Tuesday as low pressure tracks through southern Canada. That front should move through Tuesday night or Wednesday with another area of high pressure building in towards the end of the week. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... An impulse in the mid level flow is expected to pass overhead during the morning and early afternoon hours before moving out over the ocean. Meanwhile, a weak surface front will drop slowly through our region from north to south. We are anticipating additional showers and thunderstorms today, both during the morning and afternoon hours. There is not expected to be as much instability when compared to the past few days. Mixed layer CAPE values are forecast to rise only into the 500 to 1000 J/Kg range, so the chances for severe storms with strong wind gusts should be limited but not zero. Precipitable water values will remain in excess of 2 inches for much of the day, especially from the Interstate 95 Corridor southeastward, so locally heavy downpours are possible. There may be some flooding of roadways, poor drainage areas, and small streams and creeks. It remains difficult to forecast the timing and location of any convection, since much of it will develop along remnant boundaries from the thunderstorms that occurred on Thursday and during the overnight. High temperatures should be mostly in the 80s with a variable wind less than 10 MPH. && .SHORT TERM /6 PM THIS EVENING THROUGH 6 AM SATURDAY/... The frontal boundary is forecast to sink to our south and weaken tonight. While there may be some lingering showers and thunderstorms into this evening across northeastern Maryland, Delaware and southern New Jersey, most of the night should be precipitation-free in our region. A weak impulse traveling in the northwesterly mid level flow is expected to pass overhead tonight with slightly drier air following in its wake. As a result, we are anticipating some clearing for tonight. Some areas, especially those that receive additional rainfall, may see patchy fog late tonight. The wind is forecast to be light and variable with low temperatures mainly in the upper 60s and lower 70s. && .LONG TERM /SATURDAY THROUGH THURSDAY/... Overview... After an active stretch, a more benign pattern develops for the weekend and into next week. Ridging over the center of the country begins to shift east and gradually break down as a rather strong trough, the most robust we've seen in awhile, digs into the Great Lakes region. As the ridge folds over, a chunk of warmer air from out to the west will be advected towards the region, and is likely to lead to another uptick in the heat for the start of next week. The main surface feature to watch next week will be a cold front approaching from the west as low pressure tracks through southern Canada ahead of the approaching trough. Timing of this front remains uncertain (the overall trend is slower) but when it comes through it will likely bring a round of showers and thunderstorms. A trend towards high pressure and drier weather is then favored for late week. For sensible weather concerns this period, overall it looks like a fairly low impact stretch. Sunday through Tuesday will be quite hot and fairly humid. While each day will be marginal in terms of needing any heat advisories, the combined effects of these three days, continued warm overnights, and the recent lengthy stretch of similarly hot and humid conditions with no breaks may lead to some problems. Other than that, will monitor for any severe weather or hydro concerns with the frontal passage, but it does not look too alarming at the moment with shear on the weak side and the magnitude of frontal forcing in question. Dailies... Saturday-Saturday night... Raised PoPs a bit on Saturday (mostly slgt chc, some low end chc) especially to the south. This has seemed possible for awhile, and while Saturday by no means looks like a day with widespread showers and storms, does look like some isolated to widely scattered convection is possible. This is mainly driven by a continued warm and humid air mass and the continued nearby presence of the weak and diffuse surface front from earlier in the week. Additional surface boundaries such as the sea breeze may aid in producing isolated convection. Still a mainly dry day overall as high pressure will be starting to build in from the north. Warm and humid again Saturday with highs near 90 as the "cold front" to the south is very weak and will be mostly washed out by then. Sunday-Sunday night... Rain chances drop further on Sunday with weakening high pressure to the north moving a little further south. Still a warm and fairly humid air mass in place, but little forcing for ascent so while I can't totally rule out a shower especially over Delmarva or southern NJ, should be a mainly dry day and another warm night. Heat index values during the day Sunday rise towards 95 to 100, so approaching advisory criteria but more likely to stay below. Monday-Monday night... The trend is slower with the approach of a cold front next week as weak high pressure looks to remain our primary influence on Monday. Cut PoPs back to below mentionable levels on Monday. Monday will be quite hot ahead of the front, with highs getting into the low to mid 90s. Humidity, while not oppressive, will remain elevated, and heat index values may approach advisory criteria in some areas. Another warm and humid night. Tuesday-Wednesday... Likely to be the most active part of the period as low pressure tracks towards the southern Hudson Bay and into Quebec by midweek. A cold front will approach from the west as it does so and as a large trough digs into the Great Lakes. Ahead of the front, PWAT values will rise and humidity will probably peak on Tuesday, another very warm day. A band of showers and thunderstorms will likely move through ahead of the front, but the timing remains somewhat uncertain. Current trends favor the best rain chances being late Tuesday into Tuesday night. May dry out by Wednesday, but given what's happened with the last couple of cold fronts, would not be too surprised if this one also slows down enough to keep warmer and more humid air and even a storm risk still around on Wednesday, especially to the south. Am not currently too concerned with severe or hydro issues from this system. Wind fields look pretty weak and always worry about a lack of forcing with low centers tracking this far north. Just something to keep an eye on. Later next week... Once the midweek front passes, assuming it doesn't stall or wash out, then we should trend towards drier weather towards the end of next week. With the more robust troughing digging in to our west, we may finally see a somewhat more substantial drop in temperatures or at least humidity towards the end of next week, but still some uncertainty on that. && .AVIATION /12Z FRIDAY THROUGH TUESDAY/... The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas. Today...Mainly VFR. However, scattered showers and thunderstorms will bring localized MVFR/IFR conditions along with the potential for downpours. Variable wind less than 10 knots. Medium confidence overall with low confidence in the timing of any precipitation. Tonight...Mainly VFR in the evening. Areas of MVFR developing late tonight. Variable wind 6 knots or less. Medium confidence. Outlook... Saturday-Saturday night... Mainly VFR during the day Saturday. Slight chance of afternoon showers or thunderstorms mainly near and south of PHL. Overnight, fog development is possible, with some areas of IFR or lower possible. Winds light and variable. High confidence overall except low confidence in how widespread fog will be overnight. Sunday-Sunday night... Mainly VFR. Patchy fog possible Sunday morning. Southwest wind 5 to 10 kt. Moderate to high confidence. Monday-Monday night... Mainly VFR. Southwest wind 5 to 10 kt. Moderate to high confidence. Tuesday-Wednesday... Prevailing VFR, but a band of showers and thunderstorms will likely move through the region ahead of a cold front with a period of restrictions. Winds mainly west- southwest at 5 to 10 kt, becoming more west or west-northwest on Wednesday. Low confidence. && .MARINE... A westerly wind 5 to 10 knots this morning should back to the southwest and south this afternoon. The wind is forecast to return to the west, then to the north tonight. There is a chance of showers and thunderstorms for today into early this evening. Waves on our ocean waters will be 2 to 3 feet. Waves on Delaware Bay are expected to be 2 feet or less. Outlook... Saturday through Tuesday... No marine headlines are anticipated. Rip Currents... There is a low risk for the development of dangerous rip currents for today along the coasts of Delaware and New Jersey. A west wind 5 to 10 MPH is forecast to become southerly. Breaking waves are expected to be 1 to 2 feet with a medium period swell from the south. The low risk is anticipated to continue on Saturday. A northeast wind 5 to 10 MPH is expected to become southeast. Breaking waves are forecast to range from 1 to 2 feet with a medium period swell from the southeast. && .EQUIPMENT...
