Synopsis for the coastal waters from sandy hook nj to fenwick island de and for delaware bay.. High pressure shifts to off the new england coast during Saturday into Saturday night. Meanwhile, low pressure forms over the central plains and deepens rapidly as it moves northeastward into the great lakes by Sunday morning. This intense low will continue across southeast canada Sunday and Sunday night, with an attendant cold front crossing the mid-atlantic region Sunday afternoon. High pressure will build in behind the low late Monday and Tuesday. A weak low pressure system may affect the area around Wednesday, then high pressure should return by Friday.

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kphi 230232 afdphi area forecast discussion national weather service mount holly nj 932 pm est Fri feb 22 2019 Synopsis High pressure shifts to off the new england coast during Saturday into Saturday night. Meanwhile, low pressure forms over the central plains and deepens rapidly as it moves northeastward into the great lakes by Sunday morning. This intense low will continue across southeast canada Sunday and Sunday night, with an attendant cold front crossing the mid-atlantic region Sunday afternoon. High pressure will build in behind the low late Monday and Tuesday. A weak low pressure system may affect the area around Wednesday, then high pressure should return by Friday. Near term until 6 am Saturday morning For the 930 pm update, some temperature adjustments were needed as the more sheltered areas especially (such as the new jersey pine barrens) are cooling faster. Low temperatures were adjusted down some for several areas as a result. No other significant changes were needed at this time. Lower dew points remain across much of the area and this trend may continue overnight as the strong surface high starts to become more centered to our north- northeast. A wealth of high level cloudiness continues to move across the region associated with an upper-level jet. Some sprinkles and light rain south and southwest of southern delaware is anticipated to remain there due to drier air northward. Short term 6 am Saturday morning through 6 pm Saturday Biggest change in this period was to delay the onset of rain through the day time hours. Most of the region, with the exception of DELMARVA and far south jersey, will likely not see any rain during the day time hours. This slower arrival of rain makes sense given how slow the surface high will be to shift off shore away from our region. Highs look to be mostly in the 40s across the region. Long term Saturday night through Friday Most of the action in the long term is in the first couple of days, i.E., Saturday night through Monday. An upper level shortwave ridge and surface high pressure off the new england coast will give way to a strong shortwave trof and assocd deepening low pressure, moving into the great lakes by Sunday morning. Precip will overspread the area from SW to NE during Saturday evening and may become moderate to heavy at times overnight. Temperatures should slowly rise overnight, however they may hover around freezing for a few evening hours in the poconos. Thus a bit of freezing is possible, but confidence is not high, and duration would be rather brief. Otherwise, the heaviest rain should occur in a 6- to 12-hour window centered around 12z Sunday. Expected total rainfall is around an inch and no significant flooding is expected. See the hydro section below for more info. Rain will end with a sharp cold front passage Sunday afternoon. Forecast instability is very limited, but showers with the front could contain some isolated thunder. High temps Sunday may reach mid 50s to mid 60s, especially after rain ends and winds with the frontal passage mix the pbl. Behind the front, the main issue becomes the wind. Continued deep low pressure over southeast canada with result in a strong pressure gradient and gusty wnw winds. Winds a few thousand feet aloft are forecast to reach 50-60kt, but downward mixing of momentum will be limited as the surface cools after sunset. A wind advisory could eventually be needed late Sunday into Sunday night. A post-frontal trof is forecast to move through around 12z Monday with an apparent secondary surge of winds. Also daytime heating will promote mixing and enhanced downward mom xfer. Thus the strongest winds are expected Monday morning, when gusts could reach 50kt requiring a high wind warning. By Tuesday the low finally pulls away into the gulf of st. Lawrence and high pressure builds in over the mid-atlantic from the west. This will in fair and relatively calm conditions. The forecast grids beyond next Tuesday were not changed for this package. There is considerable uncertainty and variation between the GFS and the ECMWF regarding temps and possible light precip, but as of now no significant weather is expected at least through mid-week. Aviation 02z Saturday through Wednesday The following discussion is for kphl, kpne, kttn, kabe, krdg, kilg, kmiv, kacy and surrounding areas. Overnight...VFR with high level cloudiness. Northerly winds around 5 knots, becoming light and variable to locally calm. Saturday...VFR overall, however ceilings will gradually lower as |
some light rain starts to arrive from the southwest late in the day. For the phl area northward, any light rain should hold off until Saturday evening. Light and variable winds, becoming northeast to east around 5 knots, then southeast 4-7 knots in the afternoon. Outlook... Saturday night... Cig vsby restrictions expected in rain and fog. Winds E SE 3-8 knots. High confidence. Sunday... Am restrictions in rain and low clouds, but with pm improvement. W SW winds increasing to 15 to 25 knots with gusts of 30 to 35 knots by late day continuing into the evening. Moderate confidence. Monday...VFR but with strong W NW winds expected at 20-25 potentially gusting 40 to 50 knots. Moderate confidence. Tuesday...VFR with NW winds 5-10 knots. Moderate confidence. Wednesday... MainlyVFR but with occasional reduced CIGS vsbys possible in scattered rain or snow showers. Moderate confidence. Marine Winds and waves are expected to remain below small craft advisory conditions through Saturday. Outlook... Saturday night thru Sunday... Winds seas increasing with sca conditions possible by late Saturday night into early Sunday and gale conditions possible by late day Sunday. Sunday night thru Monday night... W NW gales expected. Storm force winds possible Monday. Tuesday and Wednesday... Winds seas diminish to below sca levels on Tuesday and remain so on Wednesday. Hydrology There are a couple changes to note with the 12z GFS nam solutions. One, the onset of the precipitation is slower. Two, qpf has come up a little bit. So other than the delmarva, the rains may now hold off until Saturday evening for much of the forecast area. The majority of the rain will fall Saturday evening through midday Sunday. The marfc is using between 1.00 to 1.50 inches of rain to drive their hydrologic models today. Before discussing stream river response, I wanted to mention that much of the snow we received a couple days ago has melted. Other than far NW nj and the southern poconos, there isn't much left on the ground. It doesn't even look like it snowed here in burlington county. This will help as much of the melted snow is moving through the river systems now vs. This weekend as it's raining. The only real swe to mention is up across carbon and monroe counties where up to 0.25" remains. Elsewhere, the swe is pretty much hydrologically insignificant. Using the 1.00 to 1.50 of qpf, we are seeing responses at our forecast points. No flooding is currently forecast, but models do put some crests near bankful. Over the weekend, keep an eye these forecast points... The north branch rancocas at pemberton, the millstone river at blackwells mills, the passaic river at millington and pine brook, and the rockaway river at boonton. Outside of the passaic river, flooding potential is low on our other mainstem rivers. So as the event unfolds Saturday night, look for minor flooding across areas of poor drainage and in low-lying areas. Some smaller creeks that have been prone to high water the last six months will be prone once again this weekend. This water will runoff make it into the above mentioned larger creeks and streams on Saturday night. Rises can be expected late Saturday night, Sunday, Sunday night, and maybe into Monday. If flooding occurs at any of our forecast points, it appears the flooding wouldn't initiate until Sunday night. Phi watches warnings advisories Pa... None. Nj... None. De... None. Md... None. Marine... None. Synopsis... Amc gorse near term... Gorse short term... Johnson long term... Amc fitzsimmons aviation... Amc gorse marine... Amc johnson hydrology... Kruzdlo |
