Area Forecast Discussion National Weather Service Mount Holly NJ 934 PM EDT Mon Jun 1 2020

SYNOPSIS. High pressure will settle off of the Carolina coast later tonight, then a warm front lifts north through the region later Tuesday. A cold front will approach by late Wednesday as low pressure moves out of the Great Lakes. That cold front will stall over the region through the end of the week. Another cold front will then approach Friday or Saturday as another area of low pressure moves out of the Great Lakes. High pressure should finally start to build back in from the west by later in the weekend.

NEAR TERM /UNTIL 6 AM TUESDAY MORNING/. As of 930 PM, some mid level clouds continue mainly across the northern areas within the northwesterly flow aloft. Meanwhile, some cirrus is working in from the west well in advance of a warm front and associated low-level warm air advection. The presence of strong mid to upper level jets is helping to pull the cirrus into our area on the northeast edge of a ridge. A short wave riding the periphery of the ridge is located in the upper Great Lakes this evening and this feature is forecast to drop southeastward toward our area nearing daybreak. Some showers should occur with it to our west, however given the dry air in place over our area in the lower levels it is less certain if any of those showers survive this far east. Otherwise, clouds are expected to be on the increase and thicken at least some through the night. The winds have settled now and temperatures will drop quicker in the more rural areas before stabilizing as more clouds arrive. Just made some tweaks again to the hourly grids to keep them current.

SHORT TERM /6 AM TUESDAY MORNING THROUGH 6 PM TUESDAY/. A weak trough will develop near or over portions of the region on Tuesday. Models indicate that some showers may develop along the boundary as some mid level energy rotates through. While confidence is not high that we will see much in the way of showers, will continue to mention some rain in the forecast with better chances as we head towards the evening when the trough starts to push to the east.

Skies will become cloudy by early morning and ceilings will lower some through the day. Winds will be out of the west to southwest around 10 to 15 mph with a few higher gusts possible through the afternoon.

With a west to southwest flow at the surface and up through the lower levels of the atmosphere, we should see some warming take place. 850mb temps will continue to rise through the day and surface temps should respond in kind. Expect highs to reach into the low to mid 70s through much of the region with some 60s across our northern and western most areas. If only we didn't have building cloud cover, temperatures would be able to build into the low to mid 80s. We will just have to wait another day before things really start to heat up .

LONG TERM /TUESDAY NIGHT THROUGH MONDAY/. Overview .

Active weather likely for the mid and late week period as multiple disturbances impact the mid-Atlantic. Initially, large scale ridging over the central US will begin to break down in favor of more zonal flow over the East. Multiple shortwave disturbances will track along the northeast flank of the weakening ridge, with accompanying surface lows. These "ridge riders" will bring several chances for showers and thunderstorms during the mid and late week period. By the weekend, high amplitude ridging will likely develop over the center of the country with troughing on either side of it, over both the Northeast and the Northwest. The ridge positioning should favor surface high pressure building into our region, bringing with it a cooling and drying trend towards the weekend and early next week. Main concerns for this period will revolve around potential for severe convection, especially on Wednesday and Thursday.

Dailies .

Tuesday night . Could be an unsettled night with a warm front draped to our north and a surge of elevated instability moving in by later in the night. The first of multiple shortwaves riding along the ridge's edge also tracks just to our north overnight. This combination should bring a risk of showers or even a couple of thunderstorms overnight. Best rain chances will be closest to the warm front, which right now looks to be over the northern half of the area, but some risk exists everywhere.

Wednesday-Wednesday night . Ridging over the center of the country will flatten out considerably on Wednesday. Meanwhile, another shortwave disturbance gets caught up in the fast west-northwest flow around the eastern flank of the decaying ridge. At the surface, the warm front will remain over or just north of the region as a wave of low pressure dives southeast out of the Great Lakes, with a cold front trailing behind it. Conceptually, this is a classic Northeast US severe weather setup. Strong mid level flow (50 to 60 kt at 500mb) and indications for a remnant EML to be advected into the region are major positives for severe weather. Guidance indicates highs in the upper 80s to low 90s Wednesday, which should allow plenty of instability to build especially as moisture also increases. In terms of failure mechanisms, the main thing to watch would be a potential round of morning convection from upstream which could stabilize the atmosphere if it does not push away in time. There is also a chance that the next shortwave may come in too slowly to take advantage of peak heating. So while this event has a fairly high ceiling potential if all comes together right, for now we are in more of a watch and wait period. SPC Day 3 Outlook has western portions of the area in a slight risk for severe weather with a marginal risk further east, and given confidence levels at this stage that seems a reasonable starting point.

Thursday-Saturday . Mid and upper level flow turns fairly zonal over the region during this period. For Thursday, sensible weather will be impacted by how far south the cold front makes it on Wednesday night. If it fails to clear the region, which seems probable, then another round of convection would be expected, especially in southern areas. A lower, though non-zero, severe risk on Thursday as shear decreases. May be more of a locally heavy rain concern, but plenty of time to watch that. Another warm to hot day likely even north of the front, which will be starting to decay.

By Friday, additional uncertainty arises as another shortwave moves into the Great Lakes. By then, a deepening trough over the West will be aiding in downstream ridge development over the central US. This in turn will favor a deepening of this next shortwave as it approaches our region. Another area of low pressure will pass through southern Canada and send another cold front towards the region by Saturday. Meanwhile, the cold front from the midweek period may still be lingering over our area on Friday, although it will have largely washed out by then. Still, with multiple boundaries in play, this is a recipe for continued unsettled weather. Plenty of spread in the guidance, and confidence is low on when the rain chances will be best. Have mainly chance PoPs on both days; most indications are Friday will have the better opportunity, and if the trailing front is fast enough Saturday may stay mainly dry as seemed to be the general trend in the 01.12z guidance. But this will all be largely dependent on timing. The overall dynamics are not as impressive as they are during the midweek period, so am not too concerned about severe weather late week, more likely just ordinary convection. Warm conditions continue Friday and Saturday.

Sunday-Monday . Regardless of what happens late this week, the pattern is supportive of drier weather for this period. Upper level troughing moves overhead Sunday then shifts east Monday, while surface high pressure begins to build in from the northwest. Should be a quiet and pleasant couple of days with low humidity and temperatures near or a bit below average.

AVIATION /02Z TUESDAY THROUGH SATURDAY/. The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.

Overnight . VFR. Southwesterly winds around 5 knots, becoming light and variable at several terminals. Increasing high level clouds. High confidence.

Tuesday . VFR ceilings. West to southwest winds around 10 knots with some afternoon gusts 15-20 knots. A few showers possible. Low confidence with timing and coverage of any showers.

Outlook . Tuesday night . Sub-VFR possible especially north of PHL due to low clouds and showers. Light southwest flow. Low confidence on extent of sub-VFR conditions.

Wednesday-Wednesday night . Prevailing VFR conditions expected, however scattered showers and thunderstorms with localized restrictions will be possible. Some storms may be strong to severe. Westerly wind around 10 to 15 kt becoming light northwest overnight. Moderate confidence.

Thursday-Thursday night . Prevailing VFR, with scattered showers and thunderstorms possible mainly in the afternoon and overnight and mainly south of PHL. Light northwest winds becoming light southwest in the afternoon then light and variable overnight. Moderate confidence.

Friday-Saturday . Mainly VFR, but additional rounds of showers and thunderstorms are possible especially Friday. Light southwest winds Friday becoming light northwest on Saturday. Moderate confidence.

MARINE. Sub-advisory conditions expected through Tuesday. West to southwest winds mainly 10 to 15 knots with gusts up to 20 knots. Seas 2 to 4 feet.

Outlook . Tuesday night-Friday . Winds and seas are expected to remain below SCA criteria. Several chances for showers and thunderstorms are expected.

Rip Currents . A low risk for the development of dangerous rip currents continues through Wednesday, as winds turn more southerly and with waves in the surf zone only about 2 feet.

PHI WATCHES/WARNINGS/ADVISORIES. PA . None. NJ . None. DE . None. MD . None. MARINE . None.
