10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. 6/2/2019. Many thanks to a user for reporting an error on one of the Edit pages. The switch to PHP 7.2 caused many pages that previously worked to quit working. I fixed many but I still depend on users to report ones I missed. Please report errors HERE or send an email to me at L-36.com. Allen |

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kphi 181948 afdphi area forecast discussion national weather service mount holly nj 348 pm edt Fri oct 18 2019 Synopsis A large area of high pressure will gradually build east towards our region through Saturday before shifting off shore Saturday night. Low pressure is expected to progress from the carolinas on Saturday night to the waters off the middle atlantic coast on Sunday and Monday. A cold front is anticipated to approach from the west on Tuesday and it should pass through our region on Tuesday night. High pressure is expected to follow for Wednesday and Thursday. Near term until 6 am Saturday morning Low pressure to our northeast will continue to pull further away tonight, and a center of high pressure will move overhead. This will cause the winds to drop off to very light levels tonight, and also present a good setup for radiational cooling with clear skies in place. The main forecast issue tonight will be the low temperatures and associated frost and freeze concerns as many places will see their coldest night of the season so far. Similar to previous forecaster, am definitely leaning on the cold side of the guidance envelope for tonight, and have generally lowered the lows another degree or two. Because of this, have expanded the frost advisory in a couple of areas, basically in an effort to surround the urban corridor, which will be too warm for frost. In addition, have issued a freeze warning for sussex county in northern new jersey. It will probably be marginal on whether we see a freeze, but temperatures often drop off very efficiently in these conditions, so felt the warning was justified. One possible inhibiting factor to cooling is that we do start to see WAA aloft tonight. However, with the high moving overhead we should decouple after sunset and see a fairly strong inversion start to develop at the surface, mitigating the warming aloft. Outside of the frost freeze concerns, it will be an uneventful overnight across the area. Short term 6 am Saturday morning through 6 pm Saturday A very nice day is expected for Saturday. The high pressure center will remain almost directly overhead for most of the day before starting to shift off to the east towards evening. Dew points remain low and we start to pick up better WAA aloft so as we mix out we should make a strong recovery after the morning's cold start. Most areas should make it into the low 60s, with a few mid 60s possible. Dry conditions expected with plenty of sunshine. Winds will also be light, gradually turning more southwesterly during the afternoon. Long term Saturday night through Friday Overview: the main periods of concern in the long term are Sunday when our area could be on the northwestern fringe of the precipitation shield of nestor, and another period Tuesday into Tuesday night with the approach of the next cold front. Changes: no significant changes in the long term forecast with this issuance. Details: Saturday night through Sunday... Tropical low pressure is expected to move northeastward across the carolinas on Saturday night, before passing off the coast near CAPE hatteras on Sunday. The low is forecast to meander off the middle atlantic coast into the early part of the new week. Our region should be on the northwestern edge of the clouds and the precipitation associated with the system from late Saturday night into Sunday. We will continue to mention a chance of rain for northeastern maryland, delaware and southern new jersey. While the NAM has a track closer to the shore, the skill of the NAM is limited at that range, so have gone with a non-nam blend through this period. Consequently, do not expect any significant wind concerns for our land zones with nestor. Monday... Surface high pressure is expected to nose down from the north and northeast for Monday as the clouds and rain push out to sea. Tuesday into Tuesday night... Strong low pressure is expected to lift from the upper mississippi river valley and the western great lakes on Monday into western ontario on Tuesday. The feature is anticipated to pull a cold front through our region on Tuesday night. Based on the expected upper level flow and the position of the surface low, we are favoring the slower ecmwf timing of the front. We will continue to mention a chance of showers ahead of and with the boundary. Wednesday and Thursday... It appears as though high pressure will build from the southeastern states on Wednesday to the waters off the middle atlantic coast on Thursday. We are expecting dry weather both days. Friday... Another cold front could approach the region at the end of the week, but the timing of this is uncertain until we see the timing of the mid week front. Aviation 20z Friday through Wednesday The following discussion is for kphl, kpne, kttn, kabe, krdg, kilg, |
kmiv, kacy and surrounding areas. Tonight... VFR. Northwest winds continuing but winds will diminish early tonight to only around 5 kt and may go nearly calm or light and variable in some areas later tonight. High confidence. Saturday... VFR. Light westerly or northwesterly winds in the morning turning to the southwest in the afternoon, but speeds remaining light at only around 5 kt. High confidence. Outlook... Saturday night... StartingVFR conditions, and should stayVFR for most TAF sites. At kilg and kmiv especially, conditions could lower to MVFR or ifr toward morning. South to east wind 6 knots or less. High confidence on most aspects except timing of MVFR or lower conditions at kilg and kmiv. Sunday... MVFR or even ifr conditions are possible, especially for the delaware valley sites (kphl, kilg, kpne, and kttn) and the coastal sites (kmiv and kacy) with rain and low ceilings. Moderate confidence we will see a period of MVFR or lower at this sites, but low confidence on the timing as it isn't likely to stick around all day. East wind 5 to 10 knots, becoming northeast. At kmiv and kacy, higher winds, especially in the afternoon are possible; wind speeds of 10 to 20 kt with gusts up to 25 kt possible. Sunday night... Lingering low clouds should clear out early in the evening leading to mostly VFR conditions. Northeast wind 5 to 10 knots, becoming north. High confidence Monday...VFR conditions expected. Northeast to east wind 5 to 10 knots. High confidence. Monday night... StartingVFR, but conditions could lower to MVFR or even ifr with rain showers, primarily at kabe and krdg late in the night. East to southeast wind 5 to 10 knots. Low confidence. Tuesday... MVFR or even ifr conditions are likely to spread across the region through the day with periods of rain showers. High confidence on conditions belowVFR, but low confidence on the timing of flight category changes. Southeast to south wind around 10 knots. Tuesday night... Starting off as MVFR or ifr, but conditions should quickly improve toVFR behind a cold front which will be crossing the region overnight. Winds starting southerly 5 to 10 kt, but will have an abrupt shift to northwesterly with the cold front. Moderate confidence on the overall pattern, but low confidence on the timing. Wednesday... MostlyVFR conditions likely. Westerly winds of 5 to 15 kt. Moderate confidence. Marine Conditions are expected to remain below SCA criteria through Saturday. Northwest winds 10 to 15 kt tonight gradually becoming southwest on Saturday and decreasing. Seas 2 to 3 ft. Outlook... Saturday night through Sunday morning... Winds and seas should stay below SCA criteria. Sunday afternoon through Monday morning... East and northeast wind gusts above 25 kt are likely. Gusts may get close to gale force, but expect conditions to stay just below gale criteria at this time. Waves are expected to build to 4 to 7 feet on our ocean waters. Monday afternoon and Monday night... While wind gusts should drop below 25 knots, waves on our ocean waters are forecast to remain in the 4 to 6 foot range. Tuesday... A southeast to south wind may gust in excess of 25 knots. Waves on our ocean waters should be around 5 to 6 feet. Tuesday night and Wednesday... An abrupt shift to northwesterly and westerly winds with gusts above 25 kt is likely Tuesday night continuing into Wednesday. Phi watches warnings advisories Pa...
