5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues. |

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kphi 210114 afdphi area forecast discussion national weather service mount holly nj 914 pm edt Wed jun 20 2018 Synopsis A developing low pressure system and its associated fronts will traverse the region tonight. Canadian high pressure moves into the northeast late Thursday into Friday while a stalled front remains just to the south. Low pressure moving from the eastern great lakes into northern new england will lift a warm through the region on Saturday, followed by a cold frontal passage late Sunday. A sprawling area of canadian high pressure builds into the area through the first half of next week. Near term until 6 am Thursday morning Showers were scattered across eastern pennsylvania, northeastern maryland, delaware and new jersey around 9:00 pm. The precipitation is forecast to become more organized overnight. Diffuse low pressure was located in the upper ohio river valley early this evening. The feature is expected to become better developed overnight with its center reaching southeastern pennsylvania around 2:00 am. The low is anticipated to pass off the new jersey coast before daybreak. The low should be traveling along a weak surface boundary that extended eastward across southeastern pennsylvania and up into the new york city area this evening. As the low approaches, the boundary is expected to provide a focus for the development of additional showers and thunderstorms. Precipitable water values in the 2.00 to 2.25 range indicate that there will be abundant moisture available. As a result, we continue to expected some bands of heavy rain. While the model guidance has been varying with the placement of the axis of heavy rain, it seems as though the general average or consensus puts it across southeastern pennsylvania and central new jersey. Although, locally heavy showers and thunderstorms also seem likely on the upper delmarva and in southern new jersey. The expected rainfall amounts suggest some localized flooding of roadways and areas of poor drainage overnight. It seems as though we will be able to handle the situation mainly with flood advisory products. The wind should be light and variable for much of the night, with the direction favoring the south on the upper DELMARVA and in southern new jersey. The wind is forecast to shift to the north and northeast at most locations toward daybreak as the low begins to pass off the coast. Minimum temperatures are forecast to range from the upper 50s in the poconos to the lower 70s in our southern counties. Short term 6 am Thursday morning through 6 pm Thursday Most of the showers associated with the system from Wednesday night will have moved S E of the area by Thursday morning. A few showers may remain across ERN de and SE nj however. These showers will continue east and be offshore by noon. Clouds will decrease from NW SE as drier air filters into the area. Temperatures will reach the low mid 80s in most areas Thursday. Dew points will be somewhat less than Wednesday. Winds will be north to northeast around 10 mph. Long term Thursday night through Wednesday Thursday night through Sunday... there will be a brief reprieve between systems Thursday night into Friday before the next system affects the area over the weekend. To start the period Thursday night, a quasi-stationary front will be situated just south of the area while a high pressure system moves from ontario and quebec into new england. This will set up a cooler E NE flow over the area. Mainly clear to partly cloudy skies Thursday evening will give way to increasing clouds overnight as mid and upper level moisture begins streaming in ahead of the next system. In addition, there are some indications that a marine low stratus deck may form and effect portions of central and southern nj into the delmarva. The area should remain precip free for Thursday night however with lows mainly in the 60s, except 50s over the southern poconos. Tricky forecast for Friday. Moisture associated with the next approaching low over the ohio valley will continue to push eastward toward the region in the SW flow aloft. Meanwhile, at the surface, the stationary front remains stalled just to our south with cool E NE winds over the area to its north. This will be associated with the westward extent of the ridge over new england. Despite the moisture advecting in aloft, there will be a dry layer in the lower levels associated with the ridge and this will tend to limit precip over the area. That said, still think there may be some scattered to isolated showers over the area under the mainly cloudy skies so we do have chance to slight chance pops in for most areas by Friday afternoon. We also trended the forecast cooler as there will be an inversion above the cooler NE flow. Generally expect highs in the low to mid 70s but it could even be a bit cooler than this. Friday night, low pressure supported by an upper trough advances northward toward lower michigan slowly pushing a warm front toward the southern DELMARVA by early Saturday. Expect an area of showers to move through associated with the isentropic lift and shortwave energy in the SW flow ahead of the upper trough. A few rumbles of thunder will be possible but this should be mainly confined to southern areas across the delmarva closer to the front. Heading into Saturday, the warm front will continue to slowly make its way northward through the area but may not make it farther north than the i-78 i-80 corridor by late day. The initial round of showers Friday night may last into Saturday morning before there should be a lull as much of the area breaks into the warm sector... So not looking like a continuous all day rain. Depending on how much sunshine breaks out temps south of the front should at least reach the low to mid 80s, if not a bit higher, with dew points climbing into the |
upper 60s to low 70s so it will be quite muggy once again! By the latter part of the afternoon into the evening attention will then turn to the thunderstorm threat ahead of a pre-frontal trough. At this point still looking at good deep layer forcing with ml capes potentially reaching 1000-1500+ j kg and deep layer shear reaching 30-50 knots. For these reasons still see the potential for severe weather given this set up... Especially near and south of the i-95 corridor in the warm sector. Indications are for a round of late day showers and thunderstorms to affect this area before moving out Saturday night as the trough moves through. By Sunday morning, area should be in another lull however the actual cold front and associated upper level trough will still be upstream. For this reason expect that a mainly dry start to the day with a mix of Sun clouds will give way to increasing chances for showers and storms arriving from the west by late afternoon as the front and the main shortwave energy aloft approaches. Still another very warm, muggy day with temps and humidity levels similar to Saturday. Sunday night through Wednesday... showers and storms with the cold front discussed above will sweep through the area with the front Sunday night into early Monday followed by clearing skies by late Monday along with falling dew points and temperatures near seasonal. Beyond this time, a sprawling area of high pressure looks to build in from the north bringing mainly clear skies with seasonable temperatures and comfortable humidity levels through mid week. Aviation 01z Thursday through Monday The following discussion is for kphl, kpne, kttn, kabe, krdg, kilg, kmiv, kacy and surrounding areas. Overnight...VFR lowering to MVFR and ifr in showers and scattered thunderstorms. The rain will become locally moderate to heavy. Variable wind 6 knots or less becoming north to northeast toward daybreak. Thursday... Generally MVFR andVFR ceilings in the morning with some clearing in the afternoon. Northeast wind 5 to 10 knots becoming east to southeast in the afternoon. Outlook... Thursday night... MVFR ceilings possible at acy and miv, with northeast wind gusts up to 20 mph. Elsewhere,VFR. Medium confidence. Friday... PredominantlyVFR. Cannot rule out brief MVFR ceilings in shra. Easterly wind gusts up to 20 mph, especially acy and phl. Medium confidence. Friday night... Low clouds and fog will lead MVFR, with ifr possible, especially late. Easterly wind gusts up to 20 mph. Low confidence. Saturday... Conditions gradually improving to MVFR, withVFR possible by afternoon, especially i-95 corridor terminals. But shra and tsra will lead to brief ceiling visibility restrictions. Southwest winds. Medium confidence. Saturday night... A return to low clouds and fog with MVFR, and even ifr possible. Winds shifting to the northwest. Low confidence. Sunday... Low clouds and fog will dissipate with a return to mainlyVFR until a late day risk of storms could bring brief restrictions. Winds west- southwest. Medium confidence. Sunday night... Showers, storms possible along with associated restrictions. Monday... Becoming mainlyVFR. Marine Overall, conditions will remain below SCA criteria overnight. Winds overnight will be mostly SE to S around 5 to 10 knots. Showers and scattered tstms. Locally higher winds and seas near tstms. Thursday, showers will end during the morning and then fair weather will arrive for the afternoon. Winds will be north to northeast at around 10 knots. Rip currents... Low risk expected on Thursday. Outlook... winds and seas may reach SCA levels late Thursday night as low pressure develops offshore. The pressure gradient between high pressure to the north and an approaching warm front to the south likely leads to continued SCA winds seas Friday and Friday night. As the warm front moves across the waters, a brisk southwest flow promotes SCA level seas through at least Saturday. A return to more tranquil, sub-sca boating conditions is expected Sunday into early next week. Phi watches warnings advisories Pa... None. Nj... None. De... None. Md... None. Marine... None.
