Area Forecast Discussion
National Weather Service Mount Holly NJ
924am EDT Sunday September 22 2019

High pressure will continue to move slowly off the Carolina coast through today. Low pressure will develop over the Great Lakes tonight and move northeast through Ontario and Quebec Monday through Tuesday dragging a cold front across the area. High pressure will build into the Northeast for midweek, with another cold front moving through the area Thursday night. Another broad surface high will follow to close the week and persist into next weekend.

Near Term - Until 6pm This Evening
930 am update: Fog is quickly dissipating in the usual spots this morning. Another warm and mostly sunny day is on tap. Made some minor adjustments to hourly temps and dew points for the next few hours, but no other changes were required at this time.

Previous discussion... Heading into the day today, the ridge aloft over the area breaks down while high pressure at the surface moves offshore. This will allow for a return flow with very warm temperatures and increasing moisture through the day. Late day, there is a chance some showers may develop to our west. They are mostly expected to stay out of our area and remain near the surface trough though there will be just a slight chance of a few showers or storms across the Poconos late in the afternoon. Highs will be mainly in the middle to upper 80s except a bit cooler along the coast, the Delaware Bay, and the southern Poconos.

Short Term - 6pm This Evening Through 6am Monday
High pressure continues to move eastward over the Atlantic Sunday night while a developing low pressure system and associated cold front moves east through the Great Lakes. This will keep the area in a mild S/SW flow resulting in warmer overnight lows compared to this morning. Skies should remain mainly clear to partly cloudy. Lows will be mostly in the middle to upper 60s...warmest over the Delmarva NE along the urban corridor through Philly. It will be a a bit cooler in the southern Poconos where lows should get down into the low 60s.

Long Term - Monday Through Saturday
Monday through Wednesday... Warmth continues Monday due to a breezy SW flow ahead of an approaching cold front. The day will begin mostly sunny followed by increasing clouds in the afternoon as this front approaches. Forecast models continue to generally back off on precipitation amounts for late day Monday with the front. It appears the timing for any scattered showers/storms approaching from the west will be towards the late afternoon into the evening by which time it will be past peak heating. This will limit instability. Also, the best deep layer forcing looks to stay to our north and west. That said, we still keep the chances for some late day scattered showers with possible storms mainly from the I-95 corridor and points N/W. Since instability will be limited, don't think any storms will be severe but they could produce some gusty winds since the flow aloft will be fairly strong. Highs Monday will generally range from the mid 80s to close to 90 across the urban corridor but it will be a bit cooler along the coast and over the southern Poconos.

The cold front moves through Monday night bringing continuing chances for some showers/storms before clearing the area by Tuesday. Tuesday then looks to be a partly to mostly sunny day with seasonable temperatures and low humidity with NW winds behind the front.

High pressure builds in Tuesday night through Wednesday bringing mainly clear skies with continuing seasonable temperatures and low humidity. Lows Tuesday night will be mainly in the 50s with highs Wednesday generally in the 70s.

Wednesday night through Saturday... The overall pattern will continue to be dominated by large scale ridging in the east meaning mostly dry and fair weather can be expected through the extended. The ridging briefly breaks down though later Wednesday night through Thursday as a cold front arrives by late day Thursday. However once again, most of the deep layer lift will remain to our north so it should be a dry frontal passage. Highs Thursday look to climb back into the 80s for much of the area ahead of the front. Ridging becomes re- established over the area for the end of next week into next weekend with sunshine and seasonably warm temperatures expected for Friday and Saturday.

Through today...Conditions expected to remain below advisory levels, although winds may gust around 20 knots at times in the afternoon.

Tonight...SW winds increase to around 15 to 20 knots with gusts 20 to 25 knots by Monday morning. Seas increase to around 4-5 feet.

Outlook... Monday through Monday night...Marginal SCA (Small Craft Advisory) conditions are likely for the coastal waters Monday into Monday night as SW winds will be 15 to 20 with gusts up to 25 knots. Seas will be around 5 feet.

Tuesday through Thursday...Conditions are expected to be below Small Craft Advisory criteria.

RIP CURRENTS... There is a MODERATE risk for the development of dangerous rip currents at New Jersey and Delaware beaches for today.
