What forecasters said that day
The local office's own words before this winter weather advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Philadelphia/Mount Holly wrote its last area forecast discussion before this winter weather advisory went out at Jan 15, 12:54 PM EST, 2 hours 19 minutes earlier.
Area forecast discussion, Jan 15, 12:54 PM EST, 2 hours 19 minutes before
Area Forecast Discussion National Weather Service Mount Holly NJ 1254 PM EST Mon Jan 15 2018 .SYNOPSIS... High pressure centered in Quebec early this morning will continue to influence our weather today. Low pressure is forecast pass across the southern and eastern Great Lakes tonight and Tuesday. A secondary low is expected to develop off the Middle Atlantic coast on Tuesday night before moving northeast toward Canada's Maritime Provinces on Wednesday. High pressure from the west is forecast to build across the southeastern and Middle Atlantic states on Thursday and Friday before moving out to sea over the weekend. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... Some ocean-effect snow has developed in eastern Sussex County, DE, late this morning and continues at this time. Needed to boost PoPs in lower portions of our Delmarva CWA for this threat. Though impacts generally should be minimal, area webcams showed a coating of snow was occurring on untreated surfaces, whereas more traveled and/or treated surfaces were generally wet. Basically kept this threat through the afternoon, using the latest HRRR as a guide for timing (for now). Did make some more upward adjustments to dew points and temperatures as well based on latest trends, with models generally a little too low in most spots with both variables this morning. && .SHORT TERM /6 PM THIS EVENING THROUGH 6 AM TUESDAY/... The influence of the high will continue to relax while a weak trough develops across the area. It will remain rather cold, but warmer than this (present) night. The trough may result in some light snow developing across wrn/nrn areas towards dawn. The airmass is still rather dry and this leads me to question how much will occur. The low confid in whether accums will occur leads me to only keep the ongoing chc pops in these areas for now. Lows tonight will be in the teens north/west and low/mid 20s elsewhere. && .LONG TERM /TUESDAY THROUGH SUNDAY/... A long wave trough is expected to settle over the eastern states for the middle part of the week. The trough should lift to our northeast late in the week, allowing ridging to build overhead from the west for the weekend. The pattern will maintain cold conditions in our region through Thursday with a warming trend anticipated after that time. It continues to appear as though weak low pressure will move across the eastern Great Lakes on Tuesday and it should pull a cold front into our region from the west on Tuesday night. We still anticipate snow on Tuesday and Tuesday night in much of eastern Pennsylvania and northern New Jersey with accumulations of 1 to 2 inches in areas to the northwest of the Interstate 95 corridor and 2 to 4 inches in the elevated terrain of the Poconos and northern New Jersey. There remains the potential for light snow from the Interstate 95 corridor southeastward. Enough warming may take place on Tuesday afternoon in advance of the cold front to cause the snow to change to rain for a time in that area. Little or no snow accumulation is anticipated for the coastal plain of New Jersey and the Delmarva with a light coating possible along the Interstate 95 corridor. The secondary low development off the Middle Atlantic coast on Tuesday night appears as though it will be too late to have any significant impact on our region. However, we will continue to keep an eye on the system in case the details regarding its development change. The low is not expected to begin deepening much until it reaches our latitude late on Tuesday night. It should lift quickly toward the waters off New England and Canada's Maritime Provinces on Wednesday. High pressure is expected to build across the southeastern and Middle Atlantic states late in the week before moving over the western North Atlantic during the weekend. The high is forecast to bring dry weather conditions and a warming trend. && .AVIATION /18Z MONDAY THROUGH SATURDAY/... The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas. Today...Generally MVFR to low VFR CIGs through the afternoon with northeast winds around 10 kts. High confidence. Tonight...CIGs will likely lower through the night, with light snow developing in the Lehigh Valley and southern Poconos by daybreak. Sub-VFR CIGs should be present in most locations by daybreak, with sub-VFR VSBYs likely at RDG/ABE once the light snow begins.
