SYNOPSIS. A cold front will move through the region later today. After that, a broad surface high will move southeastward towards New England and the mid-Atlantic for the remainder of the week into the weekend. An area of low pressure may move into the region late in the weekend or early next week.

NEAR TERM /THROUGH TONIGHT/. A shortwave trough axis and associated mid-level vorticity maxima are working through the Mid-Atlantic region at this time. A cold front is currently across the PA/NY border and will track through the forecast area from north to south as the day progresses and is anticipated to be offshore/south of the area shortly after midnight.

After this morning convection moves northeast or weakens, an additional round of convection is expected to develop along or ahead of the cold front and possibly any remnant boundaries associated with the morning convection into the early/mid afternoon hours (1-4 PM), mainly across southeast PA and central NJ. This activity is expected to move southeastward and offshore during the evening hours.

There will be a threat of severe thunderstorms with any of the more robust cells that develop. Diurnal instability will be in the 1000- 1500+ J/kg range along with deep layer effective shear around 25 kts. Mid-level lapse rates around 7 C/km and DCAPE >700 J/kg could result in fairly strong updrafts and downdrafts with small hail and strong/damaging winds possible. SPC has introduced a Slight Risk for areas near and south of Philly with a Marginal Risk for most of the remainder of the forecast area. PWats around 1.3-1.5" along with a progressive storm motion should preclude any widespread notable flash flood threat, but some localized flooding may be possible.

Expect mostly cloudy skies with highs in the low-mid 70s north/west of I-95 and around 80 degrees near/south of the Philly metro. Winds will be from the west ahead of the front, then turn northerly behind the front around 5-10 mph with higher gusts during the day. Expect lows falling into the upper 40s to 50s for most tonight along with clearing skies.

SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/. Low pressure will develop and move northward over the Canadian Maritimes during this period while high pressure gradually builds in from the north and west. In the upper levels, a large closed low will wobble through SE Canada and northern New England. This pattern will result in a dry, cool northerly flow over the area. Highs Wednesday and Thursday will generally be in the 60s to low 70s under a mix of sun and some fair weather clouds. Lows Wednesday night will be mostly in the 40s to low 50s. However by Friday morning the winds will be lighter as high pressure draws closer and this may allow temperatures to drop into the upper 30s over the southern Poconos and extreme NW NJ.

LONG TERM /FRIDAY THROUGH MONDAY/. No major changes to the long range forecast with this update. A closed upper low will meander across Atlantic Canada into this weekend with upper level ridging remaining centered to our north over eastern Ontario into Quebec. Guidance still varies in how quickly this blocking pattern will break down into the weekend, but this will ultimately keep Hurricane Sam well out to sea at our latitude as it begins moving poleward. At the surface, weak and cool high pressure will remain entrenched across the region through at least Friday and likely into Saturday. This will continue to be a largely quiet and tranquil period of weather for the region, at least through Friday/Saturday and possibly right through the weekend

High temperatures will be near to a bit below normal during this period with highs mostly in the 60s to low 70s. Lows will once again be quite chilly early Saturday with temperatures potentially getting to around or below 40 across the southern Poconos into NW NJ.

Cloud coverage looks like its going to beginning increasing into the weekend. Given that a consensus in guidance suggests this pattern will begin to break down at that time, we have maintained the slight chance of showers for Sunday and Monday but for Sunday this should mainly be just for the southern Poconos and NW NJ.

AVIATION /16Z TUESDAY THROUGH SATURDAY/. The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.

Today . Prevailing VFR, but scattered showers and thunderstorms are expected through much of the daytime hours (lingering into the evening for MIV/ACY). Restrictions are probable with any showers and storms that develop near or over terminals. Winds initially westerly around 5-10 kts will shift northerly by around 00Z. Moderate confidence overall.

Tonight . Prevailing VFR. Lingering showers and storms at MIV/ACY should end in the 03-06Z time frame. Winds northerly around 5-10 kts. High confidence.

Outlook .

Wednesday through Saturday . Prevailing VFR. Some patchy fog possible in the pre-dawn hours. Winds north to northwesterly around 5-10 kts during the daytime and 5 kts or less at night. High confidence overall.

MARINE. Winds and seas will subside slightly through early this morning, then sub-advisory conditions expected. Westerly winds around 10-15 kts with gusts up to 20 kts will become northerly by around midnight. Seas 2-4 feet. Scattered showers and thunderstorms developing in the late afternoon and evening hours.

Outlook .

Wednesday through Saturday . Sub-advisory conditions expected until maybe Saturday. Winds northerly around 10-15 kts. Seas 2-4 feet . maybe some 5 foot swells this weekend as Sam passes well to our east.

Rip Currents .

A LOW risk of dangerous rip currents is expected for Tue and Wed. Showers and a few tstms expected Tue.

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