Synopsis for the coastal waters from sandy hook nj to fenwick island de and for delaware bay.. A series of boundaries will meander through the region, finally pulling northward as a warm front by Tuesday with scattered afternoon showers and Thunderstorms possible through much of the week. These fronts will work northward as a warm front by Tuesday. An area of low pressure will form along the gulf coast and work its way towards the carolinas by late week, possibly impacting us as a coastal storm into the weekend. A cold front is then poised to impact the region Sunday behind this system.

Area Forecast Discussion National Weather Service Mount Holly NJ 948 PM EDT Sun Jul 5 2020

SYNOPSIS. A series of boundaries will meander through the region, finally pulling northward as a warm front by Tuesday with scattered afternoon showers and thunderstorms possible through much of the week. These fronts will work northward as a warm front by Tuesday. An area of low pressure will form along the Gulf Coast and work its way towards the Carolinas by late week, possibly impacting us as a coastal storm into the weekend. A cold front is then poised to impact the region Sunday behind this system.

NEAR TERM /UNTIL 6 AM MONDAY MORNING/. Convection has dissipated across the area, as diurnal instability has waned and larger-scale lift has diminished. Weak transient ridging/descent will occur for the next few hours before another low-amplitude vorticity maximum moves through the region late tonight. Not out of the question a stray shower develops in advance of this perturbation, but think this potential is too low for mention in the forecast at this point.

Potential for fog is lower tonight, especially with dew points noticeably lower in the northern/central portions of the CWA. Some localized fog is probable, but this potential seems too sparse/low for mention at this time. One thing that is expected to occur beginning late tonight is an increase in near-surface moisture from south to north, as some pooling begins to occur in advance of the next backdoor front approaching the area on Monday. Get ready for a muggy Monday.

SHORT TERM /6 AM MONDAY MORNING THROUGH TUESDAY NIGHT/. On Monday, another backdoor front approaches from the north and settles across the area, while moisture increases as PW values increase to 1.50-1.75 inches. A couple of short waves/vorticity impulses are forecast to move across the area, which will lead to an increasing chance of showers and thunderstorms through the day, especially in the afternoon. CAPE values will be between 2,000- 3,000+ J/kg, but shear continues to be marginal around 25-30 knots or less. However, with dry mid levels, DCAPE values are near 1,000+ J/kg, so some strong gusts could occur. Also, wet-bulb 0 heights are around 10,000-11,000 feet, so hail will also be possible. With the elevated PW values, heavy rainfall will also be a concern, especially where storms move slowly.

The backdoor front will remain in place Monday night, but CAPE values drop after sunset. However, there will continue to be a couple of short waves/vorticity impulses moving across the area during the evening and overnight. PW values remain around 1.50-1.75 inches, so any showers or possible thunderstorms could produce heavy rainfall.

The stalled out frontal boundary will remain across the area during the day Tuesday, but will start lifting northward later in the day into Tuesday night. There will continue to be a couple of short waves/vorticity impulses moving across the area, which will continue to lead to a chance of showers and thunderstorms. The thermodynamic/kinematic environment will be qualitatively similar to Monday, except for possibly somewhat weaker instability. Consequently, similar hazards are expected with any convection on Tuesday versus Monday.

The backdoor front will lift northward overnight Tuesday, and CAPE values drop after sunset. However, there will continue to be a couple of short waves/vorticity impulses moving across the area during the evening and overnight, so some chances of convection remain in the forecast.

LONG TERM /WEDNESDAY THROUGH SUNDAY/. A very summer-like pattern continues to hold strong through the upcoming week as the polar jet remains anchored well to the north across the Northern Tier of the country. Weak steering flow associated with a mid-level impulse will begin to organize itself in the form of a surface low by Thursday, with increasing confidence in this low impacting our region as some form of a coastal low by the end of the week and into the early portion of the weekend. A cold front looks to follow this low as a stronger mid-level trough works into the eastern U.S. Highs look to sit near to five degrees or so above average in the upper 80s to lower 90s through the week.

By Wednesday, a surface low will begin to organize beneath a southern stream shortwave perturbation somewhere along the Gulf Coast. This low will slowly work its way north and east toward the Carlina Coast through the end of the workweek. Guidance appears to have a solid handle on this leg of the forecast so far but things begin to tank from this point onward.

Yesterday, we discussed the lack in track agreement, but it appears this has improved but not at the expense of timing agreement. The EC has now come into better agreement on a further westward track taking the low over our region up the East Coast Friday into Saturday, but the GFS now progresses the low even faster, clearing our region by Friday night, yielding almost a 24 hour timing divergence. A large portion of this disagreement appears to center over the wavelength of the incoming synoptic trough over the Midwest. The EC brings a much stronger shortwave trough on the backside of this synoptic trough, something largely missing in the GFS, which keeps a more uniform singly curved trough.

Given these track differences, it is no surprise that a conflict in precipitation forecasts is also occurring. The GFS keeps the bulk of the rainfall in the eastern quadrant of the storm over the Atlantic, but brings heavier rainfall with the approaching cold front associated with the incoming trough to our west. The EC merges these features to our north after the southern low passes overhead, dry- slotting us to a greater extent ahead of the approaching cold front. At this time, anywhere from 1 to 2 inches looks possible across the region, unless significant track changes occur.

By Sunday, the surface low pulls to our north, but guidance seems unsure of the placement of the incoming cold front. Showers and thunderstorms are possible with this front, especially if it trends slower, crossing the region into the afternoon and evening. Highs Sunday look to remain similar with upper 80s to near 90 in the urban corridor. Taking a middle of the road approach, keeping the mention of Chance PoPs through early Saturday.

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

Tonight . Mainly VFR, though cannot completely rule out some patchy fog/low clouds late. Light/variable winds. Moderate confidence.

Monday and Monday night . Mainly VFR; however, a good chance of storms exists during the afternoon and evening. Sub-VFR conditions should be expected with any storms affecting the terminals. Storms may produce strong wind gusts and torrential downpours. Outside of any convection, mainly light west or southwest winds are expected, possibly becoming more southerly on Monday night. Moderate confidence overall, but low confidence on the timing of storm impacts on the terminals.

Tuesday and Tuesday night . Very similar conditions expected to Monday and Monday night. Moderate confidence.

Outlook .

Wednesday and Thursday . VFR conditions prevail with temporary restrictions in afternoon showers and thunderstorms possible. Winds generally out of the south from 5 to 10 knots with gusts to 20 knots possible in stronger showers and thunderstorms. Moderate confidence.

Friday . MVFR conditions possible with lowering CIGs amidst onshore flow ahead of an approaching surface low to our southwest. East- southeasterly winds from 10 to 15 knots with gusts to 20 knots. Low confidence in timing of this low, however.

MARINE. Tonight-Tuesday night . Conditions expected to remain below advisory levels through the period, although winds could gust around 20 knots at times. There is a chance of showers and thunderstorms each day which could lead to locally higher winds and waves.

Outlook .

Wednesday and Thursday..Sub-advisory conditions are forecast through the end of the workweek. Southeasterly winds from 10 to 15 knots and gusts around 15 knots. A few gusts to near 20 knots possible at times each afternoon, especially with afternoon showers and thunderstorms. Seas ranging from 2 to 3 feet.

Friday . Sub-advisory conditions anticipated with easterly winds from 5 to 10 knots with gusts from 15 to 20 knots. However, seas may build to 5 feet, especially across the southern three Atlantic zones.

Rip Currents .

There is a low risk for the development of dangerous and life threatening rip currents through Tuesday. However, conditions may be locally moderate near the times of low tide owing to increasing southerly flow through the period.

TIDES/COASTAL FLOODING. Minor tidal flooding is occurring with this evening's high tide again on the Atlantic coast. However, as expected, the observed levels are lower than yesterday. As a result, no coastal flood advisory will be required.

EQUIPMENT. The NOAA Weather Radio All Hazards broadcast from Hibernia Park, PA (WNG704) remains off the air until further notice due to damage to the antenna during the June 3 derecho.

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