Synopsis for the coastal waters from sandy hook nj to fenwick island de and for delaware bay.. Low pressure will strengthen as it moves northeast through the mid- atlantic region tonight and into new england on Friday. Behind the low, a cold front will cross our region on Friday. Over the weekend, the low will move farther away into the canadian maritimes, while high pressure will build in from the great lakes on Saturday and then shift to our south on Sunday. A cold front is forecast to cross the area on Monday, followed by high pressure for much of the remainder of next week.

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kphi 212231 afdphi area forecast discussion national weather service mount holly nj 631 pm edt Thu mar 21 2019 Synopsis Low pressure will strengthen as it moves northeast through the mid- atlantic region tonight and into new england on Friday. Behind the low, a cold front will cross our region on Friday. Over the weekend, the low will move farther away into the canadian maritimes, while high pressure will build in from the great lakes on Saturday and then shift to our south on Sunday. A cold front is forecast to cross the area on Monday, followed by high pressure for much of the remainder of next week. Near term until 6 am Friday morning No major changes with the 630 pm update. Some of the high resolution models show the lull continuing for the next few hours. However, based on the latest radar trends, with a broad area of heavier rain off shore (which is on track to move on shore later), and a pivot point starting to develop over the region, stayed close to the previous forecast. Low pressure continues to strengthen as it is currently near the central chesapeake bay and moving northward. The highest rain amounts so far have been over far northern DELMARVA and portions of far SE pa (mostly chester, delaware, and upper montgomery counties) where up to two 2 inches of rain has fallen. As we head through the evening, the rain will continue to fall moderate to heavy at times with the heaviest continuing to be over eastern pa (we are especially concerned with the western suburbs, berks county, and the lehigh valley) as well as portions of northern delmarva. Eastern nj may also get a round of heavy rain later this evening as the area of heavy rain current off shore moves on shore later. Even though rain amounts in this area have been less than an inch so far, if the heavy rain is coincident with the high tide, it could exacerbate the tidal flooding. Additional information on the flooding and coastal flooding is in the hydrology and tides coastal flooding sections below. By the overnight period, the heaviest of the rain will begin to wind down as the center of low pressure cuts right across the area then onward towards long island. Still expecting though that some lighter rain and wrap around showers continue overnight especially for northern and eastern zones. Also, as cooler air wraps in on the backside of the low we actually expect rain to change over to snow over the southern poconos where a couple inches could accumulate. By morning, temperatures will generally be in the low 40s except 30s over the southern poconos and NW nj. Short term 6 am Friday morning through Sunday The low will continue to deepen through Friday as it moves ne through new england. Main concern for Friday and beyond will be strong winds on the backside of the system due to the strong pressure gradient, deep mixing, and cold advection pattern. Friday morning may end up mainly dry before a strong shortwave associated with the main upper level low drops S E into the area. This will result in scattered showers redeveloping that could continue to be mixed with some snow across higher elevations in the southern poconos. Otherwise main focus will be on the winds. Winds will ramp up through the day and expect by mid to late afternoon w NW winds will be 15 to 25 with gusts of at least 30 to 40 mph. Winds will likely be even stronger for a time Friday night. Highs Friday will range from the upper 30s to mid 40s over the southern poconos and NW nj to the upper 40s to low 50s elsewhere. Friday night... Secondary cold front crosses the area early in the evening potentially resulting in a surge of stronger wind gusts. Profiles indicate 40 to 50 knot winds in the boundary layer but limiting factor for full mixing will be loss of heating with the diurnal cycle. Nevertheless, still think there will be a good potential for wind gusts at least 35 to 45 mph to be realized across much of the area so wind advisory may end up be needed. Otherwise, except for some scattered snow showers continuing in the southern poconos conditions should become mainly dry. Lows by Saturday morning will range from the 20s across the southern poconos and nw nj to the low to mid 30s elsewhere. For Saturday, the low pulls away into the canadian maritimes with strong NW winds continuing in its wake as high pressure moves into the ohio valley keeping a tight gradient over the area. Otherwise it will be dry but seasonably cool under mainly sunny skies. High pressure moves in for Saturday night and Sunday resulting in winds finally diminishing with temperatures returning to seasonable by Sunday afternoon under continuing mainly clear skies. Long term Sunday night through Thursday This extended forecast period will start out with a fairly strong cold front passage on Monday, followed by canadian high pressure for Tuesday through Thursday. On Monday a shortwv trof is forecast to move east into the ohio valley with moisture spreading ahead of it across the mid-atlantic region. Both the latest GFS and ecmwf are showing precip spreading across the area on Monday and continuing into Monday night in association with this feature and with the frontal passage. Temperatures ahead of the front on Monday should be warm enough for rain everywhere, but fairly strong cold advection behind the front may result in precip changing to snow from north to south Monday night. No significant snow accumulation is expected at this time. Temperatures on Tuesday and Wednesday look to be a bit below normal, but may moderate to near normal again by Thursday. Aviation 22z Thursday through Tuesday The following discussion is for kphl, kpne, kttn, kabe, krdg, kilg, kmiv, kacy and surrounding areas. Through tonight... Low pressure will intensify as it moves northeast through coastal de and nj this evening and tonight. This will result in relatively poor flying conditions through most of tonight. CIGS will generally range between low MVFR and ifr. Vsbys will beVFR at times but will be lower in areas of heavier rainfall. Precip should end from south to north during this evening, but CIGS will remain mostly ifr overnight. Winds will veer from ene to NW with the passage of the low Friday... Conditions should improve toVFR by mid-morning but nw winds will likely gust 25 to 30 kt during day. Brief local MVFR conditions are possible in scattered showers. Outlook... Friday night and Saturday...VFR conditions expected but NW winds will continue to gust 30 to 35 kt. Saturday night through Sunday night...VFR conditions with winds generally 10 kt or less. |
Monday and Monday night... MVFR countdowns possible in areas of rain or snow showers. Winds around 10 kt shifting from SW to n on Monday. Tuesday...VFR conditions with NE winds around 10 kt. Marine Easterly and southeasterly gale force gusts are expected to continue through the evening hours. A gale warning is now effect for the delaware bay and the delaware and nj coastal waters. There may be a lull in the gale conditions late tonight as the wind direction shifts to northwesterly. However, by Friday morning, wind speeds are expected to be above gale force once again. Northwesterly gales will then continue through the day on Friday. Outlook... Friday night and Saturday... Northwesterly gales continue for much of this period, but wind speeds should gradually drop off late Saturday into Saturday night. Sunday into Monday... Winds and seas are expected to be below small craft advisory conditions. Monday night and Tuesday... Northeasterly winds are likely to increase starting Monday night and continuing into Tuesday. Seas should subsequently increase as well. Hydrology During the last 24 hours, forecast models have been trending upward with their qpf, especially across SE pa. The 72 hour precip forecast, out of the marfc, now has a large swath of 1.50 to 3.00 inches of rainfall across the southern poconos, berks county, the lehigh valley, the philly suburbs, and NW nj. As a result, our river stream forecast points are responding. We now have about a dozen gages in at least caution action stage. While we will see a significant response across nj, SE pa has a greater chance to see water over banks. Across the intricate passaic basin in northern nj, there are about 5 gages now forecast to climb above caution stage. If the heaviest rainfall expands east into this area, minor flooding would then be expected. The millstone river in the raritan basin could also see some minor flooding. With the heaviest rainfall expected across SE pa, this is where we are seeing the most significant rises. Portions of the schuylkill and brandywine are now expected to flood. The smaller creeks and streams across SE pa and across northern delaware will also see levels approach or exceed bankfull. Additionally, the perkiomen creek, the neshaminy creek and portions of the lehigh system, especially the headwaters of the little lehigh need to be monitored. In terms of timing, the heaviest rains will fall between 18z today and 06z tonight. Poor drainage and low-lying flooding, like it always does, will initiate first. That will start to develop this afternoon. This rain runoff will move into fast responding creeks this evening. That water will then bleed into the larger rivers and streams overnight. If the rainfall and the flooding comes to fruition, I would expected river flooding to persist across SE pa through at least the day tomorrow. The passaic basin in nj responds more slowly. Any flooding that might develop there will be slower to do so and most likely last into the weekend. Tides coastal flooding No changes to the coastal flood warnings advisories have been made this afternoon, with the general expectation that widespread minor coastal flooding will occur with this evening's high tide. Local moderate flooding may be observed in coastal locations of middlesex and monmouth counties, though stevens institute ensemble guidance is indicating the more likely outcome is for levels just under moderate flood stage in most locations. In the advisory area of coastal new jersey and delaware, concern is increasing for somewhat higher levels than guidance is currently suggesting. Winds have been stronger than expected this afternoon, with gale-force gusts occurring on delaware bay and the atlantic waters for the past couple of hours. Models have trended a little higher with projected gauge levels this evening, and this makes sense owing to recent conditions. Though widespread minor flooding is the more likely outcome in these areas, some spotty instances of moderate flooding cannot be ruled out. Minor flooding is also expected on the tidal delaware river overnight. Additionally, the slowing trend of the associated coastal low with today's model runs leads to somewhat increased potential of another round of minor flooding for Friday morning's high tide, especially on the new jersey coast. If current trends continue, additional advisories for this high tide will be required. Strong offshore flow will commence on Friday, which will end the coastal flooding threat for subsequent high tides. No flooding is expected on the upper eastern shore of chesapeake bay.
