(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kphi 181343 afdphi area forecast discussion national weather service mount holly nj 943 am edt Sat aug 18 2018 Synopsis A cold front will move into the region today and this evening, stalling just south of our area Sunday. Several waves of low pressure will move along the stalled boundary through the weekend and into early next week. The stalled front will lift northward as a warm front on Tuesday, followed by a cold front on Wednesday. High pressure will build in from the west from Thursday through the end of the week. Near term until 6 pm this evening Another day of potential heavy rainfall and flooding as several rounds of showers and thunderstorms will move across the area. A surface trough remains in place across the area this morning, and will remain nearly stationary through the day. A couple of short waves vorticity impulses will continue to move across the area, enhancing lift near the surface trough which will allow for some scattered showers to continue through this morning. The main threat for heavy rainfall will begin this afternoon into this evening as a cold front approaches the area from the northwest. Showers and thunderstorms are expected to become more widespread as the front approaches and moves across the area. With pw values remaining around 2 inches, heavy rainfall will likely occur. Those areas that received heavy rainfall on Friday, as well as the more urbanized i-95 corridor will be particularly susceptible to flash flooding. Therefore we have issued a flash flood watch for eastern pennsylvania, much of new jersey, and northern delaware and maryland; basically along and north of the i-95 corridor. There will be plenty on instability for thunderstorms to develop across the area through today. However, there is limited shear and the flow aloft is fairly weak. So while there could be a few strong thunderstorms, mainly due to the instability, we do not expect much in the way of severe weather this afternoon. Before the cold front and showers thunderstorms approach later this afternoon, temperatures will warm well into the mid-upper 80s, and low 90s for some areas. However, heat index values are not expected to reach advisory levels at this time across the area. Short term 6 pm this evening through 6 am Sunday Heavy showers and thunderstorms will be ongoing across the area this evening as a cold front moves across the area. However, as the cold front continues to move southward through the evening and overnight, shower and thunderstorm activity is expected to wane some. Therefore the flash flood watch will remain in effect through midnight. While the shower activity wanes overnight, it showers may not completely drop off as there will continue to be a couple of more short wave vorticity impulses overnight. So we will keep a chance of showers and thunderstorms through the night, although the threat for flooding diminishes overnight. Long term Sunday through Friday Sunday through Monday... The cold fronts forward progress starts to slow down by Sunday and the front will stall over or just south of our area. For now, the guidance keeps the front just south of the region but there is potential for it to wobble a bit as it remains nearby through Monday. Several waves of low pressure will travel along the stalled boundary on Sunday and Monday. This will keep us in a now very familiar and unsettled pattern to end the weekend and start the week. A chance for showers and thunderstorms will exist through Monday, with the potential for heavy rainfall to occur as pwats remain around 2 inches on Sunday. Expect pwats to decrease some for Monday, down to around 1.25-1.50 inches as some drier air pushes down from the north in response to high pressure building across new england. Conditions across the region remain fairly wet as we have not had very many days where significant drying can occur. So this will once again mean that there will be the potential for flooding across our already saturated region. An upper trough will dig down and move through the region late Sunday through Monday. Some cooler air will be brought southward and that should help to keep Sunday cooler than it has been of late. However, it is short lived as the airmass will start to modify and warm for Monday. Highs in the upper 70s to low 80s on Sunday, some mid 80s possible in southern delaware due to the proximity to the stalled boundary. Generally expect highs in the lower 80s for Monday. Tuesday through Wednesday... An area of low pressure will start to organize over the midwestern states and track towards the great lakes region early in the week. As this low makes its move towards upstate new york eastern canada, it will start to push the stalled boundary to the north as a warm front. There is not a lot of instability on Tuesday as the front moves through. However, pwats remain high and the lift from the front may be just enough to allow for some convection to develop. Will continue to mention a slight chance for thunder through Tuesday. The low continues to pull northward into eastern canada and as it moves along, it will drag a cold front towards and then through our region on Wednesday. A secondary front may push through the region later on Wednesday. The bulk of the moisture looks to be tied to the primary cold front so not expecting much precipitation to occur with the second frontal passage. |
Thursday and Friday... High pressure will start to push eastward and into our area on Thursday. Expect conditions to dry out for the end of the week. However, the only fly in the ointment is the location of the front that moved through the area on Wednesday. Guidance shows the boundary stalling offshore which could keep the chance for some showers mainly across our southern and coastal areas. Aviation 14z Saturday through Wednesday The following discussion is for kphl, kpne, kttn, kabe, krdg, kilg, kmiv, kacy and surrounding areas. Today... Scattered showers will continue at times this morning, which may temporarily lead to subVFR conditions. Some stratus is moving through the region this morning (around 700ft) but is transient and should clear relatively quickly through this morning. Otherwise, expectVFR conditions to prevail through this morning and into the early afternoon. Showers and thunderstorms are more likely this afternoon into this evening as a cold front approaches.VFR conditions will continue outside of the showers and thunderstorms. However, sub vfr conditions will occur as the showers and thunderstorms move across the TAF sites. The heaviest thunderstorms activity is expected after 19z-20z. Winds today will generally be south to southwest 5-10 knots early, shifting to more westerly later today. Tonight... Showers and thunderstorms will move across the area through the evening hours. GenerallyVFR conditions are expected outside of the showers and thunderstorms. However, subVFR conditions remain possible as the showers and thunderstorms move across the TAF sites. Shower and thunderstorm activity is expected to wane during the overnight hours. Ceilings are expected to lower later in the overnight period, and may lower to MVFR or even ifr for some areas. Winds will become northwest behind the cold front, before shifting to northeast overnight with speeds around 5 knots. Outlook... Sunday through Monday... Chance for showers and thunderstorms with MVFR ifr conditions possible. Light winds through the overnight periods with northeast around 5 to 10 knots through Sunday and Monday. Gusts up to 20 knots possible on Sunday. Tuesday... Chance for showers and isolated thunderstorms with MVFR ifr conditions possible. East to southeast winds around 5 to 10 knots. Wednesday... Chance for showers and thunderstorms with MVFR ifr conditions possible. West to southwest winds around 5 to 10 knots with gusts up to 20 knots possible. Marine Conditions expected to remain below advisory levels today and tonight across the area. Multiple rounds of showers and thunderstorms will occur through today and tonight which will lead to locally higher winds and waves. A cold front will move across the area this evening and tonight which will shift winds to the northwest then northeast overnight with gusts around 20 knots possible. Outlook... Sunday... Seas and winds will increase as a boundary remains stalled south of the area waters. Winds may gust near 25 knots Sunday afternoon. Seas will rise to near 5 feet by mid morning on Sunday. A small craft advisory may be needed. Additionally, a chance for showers and thunderstorms will produce locally higher winds and waves. Monday... Seas are expected to subside early and remain below 5 feet through Monday. Winds will remain below small craft advisory criteria. Tuesday through Wednesday... Conditions expected to remain below small craft advisory criteria. Winds may gust around 20 knots through the afternoons on each day. Rip currents... a low risk for the formation of dangerous rip currents is expected to continue today. However, lightning will be a concern through the day as well.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program. |
