Fxus61 kphi 162314 afdphi area forecast discussion national weather service mount holly nj 714 pm edt Tue oct 16 2018 Synopsis High pressure will lose its influence over our weather tonight. A cold front approaching from the northwest is forecast to arrive on Wednesday afternoon. High pressure is expected to build across our region from the west on Thursday and Friday. Another cold front is anticipated on Saturday afternoon, followed by high pressure for Sunday and Monday. The next in the series of cold fronts is expected on Tuesday. Near term until 6 am Wednesday morning 700 pm update: forecast is in good shape. Made some minor adjustments to temperatures and dew points for tonight based on latest trends. Previous discussion... dry weather conditions are expected to continue into this evening with just some cirrus overhead associated with an upper level jet. An impulse traveling in the mid level flow was bringing some rain to the tennessee river valley and vicinity this afternoon. The feature is expected to progress east northeastward, passing off the middle atlantic coast late tonight. The northern edge of the area of rain is anticipated to brush across the middle delmarva and far southern new jersey overnight. The remainder of our forecast area should stay precipitation-free. Low temperatures are expected to range from the upper 30s in parts of the poconos, the lehigh valley and northern new jersey to around 50 in southern delaware and in the adjacent counties of eastern maryland. The wind should be light and variable. Short term 6 am Wednesday morning through Wednesday night A mid level trough is forecast to move from the great lakes on Wednesday morning to the northeastern states on Wednesday afternoon and evening. A surface cold front associated with the mid level feature is expected to pass through our region on Wednesday afternoon. The system will lack any significant moisture, so clouds will be limited and we will mention only a slight chance of showers from the poconos into northern new jersey. A gusty west wind is anticipated to develop on Wednesday with sustained speeds increasing to 15 to 20 mph with gusts of 25 to 30 mph. High temperatures will likely be in the 50s up north and in the lower and middle 60s in the rest of our forecast area. The sky is expected to be mostly clear on Wednesday night. Temperatures should drop into the 30s and lower 40s. The wind is forecast to be from the northwest around 10 mph, precluding the development of frost in areas that fall below the upper 30s. Nevertheless, we could see some sub-freezing temperatures in the elevated terrain of the pocono and far northern new jersey. Long term Thursday through Tuesday Thursday and Friday... The main influence through this period will be a surface high slowly building east in combination with a mid and upper level ridge propagating east as well. The combination of these two factors will lead to dry weather, and a warming trend. The warming trend will be especially noticeable Friday into early Saturday as the surface high builds east of our region, leading to low level southwesterly flow. Before the warming trend gets started, we could see a round of frost Thursday night for location northwest of the i-95 corridor. Saturday... Cold front should arrive through the second half of the day. Unlike with the Wednesday front, there should be plenty of moisture advection ahead of this front, thanks in large part to the southwesterly flow ahead of the front. For now have kept the weather type as showers, but depending on the arrival time of the front, especially if it arrives before sunset, we could see some thunderstorms across the region. Sunday through Tuesday... Dry and cool conditions are expected

through this period. Frost or even a hard freeze is possible especially Sunday night into Monday morning. Aviation 23z Tuesday through Sunday The following discussion is for kphl, kpne, kttn, kabe, krdg, kilg, kmiv, kacy and surrounding areas. Tonight...VFR with light west or southwest winds.

Northwest wind 5 to 10 knots Saturday night increasing to 10 to 15 knots on Sunday. Marine We are anticipating a westerly wind less than 15 knots into this evening.

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.
