Dry high pressure will build into the region on Friday and remain in control through much of the weekend, providing seasonable temperatures and tranquil weather conditions. Warmer, more humid, and unsettled conditions will return early next week.-- End Changed Discussion --&& .NEAR TERM /THROUGH TONIGHT/...-- Changed Discussion --The cold front has slowed down substantially and has essentially stalled over the I-95 corridor as of early this morning. Residual showers continue across much of the area with a few isolated rumbles of thunder. As we progress through the day, the front will continue to slowly crawl east, so with time, showers will ever so slowly make their way toward/off the coast. Most guidance suggests that the bulk of precipitation will be located offshore by midday. However, with the front not entirely through the area, areas east of the front will still have oppressive dew points in the low to mid 70s with PWATs near 2 inches. So, with the front virtually overhead, another round of extremely isolated pop- up showers and thunderstorms are possible this afternoon. Any storm sub-severe, however with the seasonably high PWATs, heavy downpours are plausible. Skies will be mostly overcast this morning, with gradual improvement in the afternoon from west to east. High temps will mainly be in the 80s with the warmest temperatures found north and west of the I-95 corridor which will observe earlier clearing. Any thunderstorms today will cease by sunset. Skies will become mostly clear tonight with low temperatures in the 60s for most, with low 70s in/around the immediate urban heat island and along the coast.-- End Changed Discussion --&& .SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/...-- Changed Discussion --A few thunderstorms possible on Thursday, then dry, seasonable, and pleasant conditions expected for the Independence Day holiday. An upper trough axis will push through the region Thursday through Thursday night followed by strengthening ridging Friday and through the weekend. A cold front will push offshore on Thursday, which is anticipated to be accompanied by some isolated to perhaps scattered thunderstorms, mainly northwest of I-95. There could be some isolated severe thunderstorms given the cooling mid levels and steepening mid level lapse rates, however widespread severe thunderstorms are not expected. Localized damaging wind gusts and hail possible with these storms Thursday. High temperatures will be in the mid to upper 80s, though we should finally see dew points mixing out to relieve us from the persistent humidity we`ve been experiencing as of late. Any thunderstorms will quickly diminish into the evening as the front pushes offshore. Lows will be in the 60s. For Independence Day, a rather pleasant and dry early summer day is forecast. The strengthening ridge across the region will inhibit any thunderstorm chances. The post frontal regime will translate to temperatures a few degrees below normal (highs in the low to mid 80s) and dewpoints mixing out quite nicely into the 50s under sunny skies. A great day for any outdoor holiday festivities! Friday night will be the coolest night of the stretch, with low temperatures in the mid 50s to mid 60s and dry air making for a very pleasant early summer night.-- End Changed Discussion --&& .LONG TERM /SATURDAY THROUGH TUESDAY/... Dry and seasonable conditions will continue through much of the weekend, however an isolated thunderstorm will be possible Sunday afternoon. The broad ridging will dominate the region over the weekend, Which will keep convection surpressed and temperatures near normal. Saturday will be a guarantied dry day, and another very pleasant one similar to Friday as the surface high slides overhead. High temperatures remaining in the mid 80s under sunny skies and dewpoints mixing out nicely once again to provide us with some low humidity. By Sunday, high pressure will be located offshore, resulting in some return flow and thus a slight increase in temperatures and humidity levels compared to the previous days. Highs Sunday in the upper 80s to near 90 degrees. Lows in the 60s to near 70 degrees both nights. The return flow beginning Sunday will open a window for some isolated thunderstorms by the afternoon and evening hours, mainly northwest of I-95 where some upper diffluence will begin to influence the area. By and large, most areas should remain dry though. Return flow will continue into early next week as upper ridging shifts out to sea and some troughing develops near the Great Lakes. This will result in more unsettled conditions developing again, with daily diurnally driven chances for showers and thunderstorms. Any severe threats remain to be seen. Expect temperatures to start trending slightly above normal (highs near 90 degrees and lows near 70 degrees) with increasing humidity into early next week. && .AVIATION /06Z WEDNESDAY THROUGH SUNDAY/...-- Changed Discussion --The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas. Through 12Z...Visibility restrictions will remain possible in residual rain showers for all terminals. Showers continue through 10-12Z. The thunder threat has diminished, so have removed VCTS from all terminals. As of 06Z, all terminals are primarily either MVFR or VFR, however have added in a TEMPO group between 06-10Z for most terminals where some lower ceilings may become possible. Otherwise, light winds generally out of the westerly direction around 5 kt or less. Low-moderate confidence overall. Wednesday...MVFR ceilings may linger through the morning hours for the I-95 terminals, KMIV, and KACY. Improvement to VFR is expected at all terminals into the afternoon hours with lingering ceilings lifting and scattering. A slight chance of a shower or thunderstorm in the afternoon, however confidence is not high enough to include at any terminal at this time. West- southwest winds around 5-8 kt. Moderate confidence. Wednesday night...VFR with a few high clouds, otherwise SKC. Light winds favoring a westerly component around 5 kt or less. High confidence. Outlook... Thursday...VFR. Isolated thunderstorms possible. Friday through Saturday...VFR. No significant weather. Sunday...VFR. Isolated thunderstorms possible near ABE/RDG.-- End Changed Discussion --&& .MARINE...-- Changed Discussion --The Small Craft Advisory on the Atlantic coastal waters has been allowed to expire/cancelled as of 2 AM as winds/seas have both fallen below thresholds. West-southwest winds around 10-15 kt will continue this morning, before settling out of the south-southwest around 5-10 kt this afternoon. Winds will gradually turn to west-northwest tonight, while remaining around 5-10 kt. Seas of 2-4 feet. Occasional showers and thunderstorms expected through this afternoon, before fair weather returns tonight. Outlook... Thursday through Sunday...No marine hazards expected. Rip Currents... For Wednesday, winds go more west/southwesterly and lighten to around 10 MPH or less. Seas decrease as well within the surf zone to around 2 feet. There remains a 1 foot 9 second swell from the ESE along with a frontal boundary just offshore. As a result, we will have a MODERATE risk for rip currents on Wednesday. For Thursday, winds remain light around 10 MPH or less out of the west in the morning, turning southwesterly in the afternoon. Seas decrease further, to around 1 foot. The ESE swell will be diminishing to a 1 ft 8 second swell and the frontal boundary will be further offshore. As a result, we have a LOW risk for rip currents for Thursday.
