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 |

SYNOPSIS. Strong low pressure will continue to our north tonight into Sunday. High pressure slides across our area Sunday night, then shifts to our north and east Monday. A warm front slowly lifts northward into our area by later Monday, as low pressure tracks eastward along it and crosses our region during Tuesday. High pressure builds in later Wednesday through Friday, then weakens into Saturday.
NEAR TERM /UNTIL 6 AM SUNDAY MORNING/. No major changes with the late evening update. Precipitation has mostly moved out of the region, with the exception of some precipitation possibly clipping the southern Poconos through late tonight.
Primary surface low is lifting quickly northeast into eastern Canada. High pressure will begin to slowly build into the region, but it won't be over our region until tomorrow night.
The pressure gradient will tighten over the area, and this will be accompanied by a 40-50 kt LLJ. Behind the departing low, winds shift to the west and increase to 15-20 mph with 30-40 mph gusts. There may be a few peak gusts approaching 50 mph, but current thinking is that the 50 mph gusts will neither be frequent enough nor widespread enough to warrant a Wind Advisory. Nevertheless, given these winds along with the nearly saturated ground from the rainfall last night and today may result in locally minor tree damage.
Lows tonight generally in the 30s.
SHORT TERM /6 AM SUNDAY MORNING THROUGH 6 PM SUNDAY/. High pressure builds into the Ohio Valley on Sunday. It remains gusty, with west winds 15-20 mph with 30-35 mph gusts through the day. The high moves offshore Sunday evening, and then low pressure begins to develop over the Tennessee Valley. A warm front begins to lift out ahead of the developing low and moves into far southeast portions of the forecast area by daybreak Monday. Will carry slight chance PoPs for Delmarva and the Delaware Valley, as some snow and/or rain may be possible.
Highs on Sunday will generally be in the 40s and lows Sunday night will be in the 20s and low 30s.
LONG TERM /SUNDAY NIGHT THROUGH SATURDAY/. Monday, Monday night, and Tuesday are shaping up to be a pretty messy period, especially Monday and Monday night. A warm front located to our south will be lifting northward through the day Monday into Monday night, before an area of low pressure moves along the front and moves into our area Monday night into Tuesday. Cold air will already be in place early Monday as weak high pressure weakens and retreats to our east. Precipitation is forecast to begin lifting over the warm front to south and move into our area during the morning hours. As the precipitation starts, the column should be cold enough for most places to start out as snow or a rain show mix for most many places. As the warm front slowly drifts northward through the day, warmer air aloft will lift across the area, eventually changing the snow to a wintry mix of sleet, rain, freezing rain. However, before the warm air moves in and the change over takes place, we could have a few inches of snow for portions of eastern Pennsylvania and northern New Jersey, especially from I-78 northward. South of I-78 down to I-95 corridor, an inch or two will be possible. South and east of I-95 are forecast to have an inch or less if any accumulation at all occurs.
As we move farther through the day Monday into Monday night, the warm air continues to push northward, and the freezing/frozen precipitation lifts northward as well. Areas along and north of I-80 may not lose the wintry mix for most of the night. Once the freezing rain begins to fall, there is expected to be some ice accumulations which will be on top of whatever snow falls. Storm total ice accumulations could reach a quarter of an inch across the Poconos, with lower amounts farther south where the freezing rain will not last as long.
By Tuesday, the surface low will lift across the area along the frontal boundary and warm air should be pushing across all areas and change all precipitation to all liquid rain. As the low passes to our northeast, precipitation will begin to dissipate. Once the winds shift to the west and northwest behind the low, winds will likely become quite gusty with wind gusts at least 25-30 mph by the late afternoon.
The longer part of the long term .
Tuesday night . The last of the previous system will be exiting the area Tuesday evening with some snow showers across the region behind the cold front. Colder and drier air will be sweeping across the region, so the snows will be done by midnight. Lows will drop through the 20s across the N/W areas and to around 30 for Delmarva and the Delaware Valley/S NJ areas. Winds will be from the W or NW with some gusts to around 20 mph early.
Wed thru Sat . A dry period is expected with an area of high pressure building across the area Thu/Fri and exiting offshore Sat. It will be cold at the beginning of the period with much below temperatures expected Thu. Highs that day will only be in the 20s N/W and around freezing for most other areas. A few mid/upper 30s are possible across Delmarva however. Temperatures will moderate back to near normal by Saturday with highs in the mid/upper 30s N/W and low/mid 40s most other areas.
AVIATION /02Z SUNDAY THROUGH THURSDAY/. Tonight . After an initial improvement earlier, we had MVFR ceilings move back in, but those appear to have dissipated now, so expect VFR conditions to continue overnight. Westerly winds around 10 to 15 knots with gust up to 30 knots possible. Moderate confidence.
Sunday . VFR. Westerly winds of 10 to 15 kt with gusts to 30 kt possible before winds gradually diminish late in the afternoon and evening. High confidence.
Outlook .
Sunday night . VFR. Light west winds. High confidence.
Monday-Monday night . Conditions lowering to MVFR, then IFR during the morning and continuing through the day and overnight. Snow develops during the morning, then changes to a wintry mix, then all rain late in the day and overnight. Moderate confidence.
Tuesday . IFR conditions with rain early, improving to MVFR then VFR by the afternoon. Northwest winds become gusty 20-30 knots by late afternoon.
Tuesday night . VFR. Occasional gusty west to northwest winds 20-30 knots in the evening, dropping off overnight.
Wednesday . VFR. West to northwest winds could gust 20-30 knots.
Wednesday night . VFR. West to northwest could gust 20-30 knots early, before diminishing overnight.
Thursday . VFR. West to northwest wind 5-10 knots.
MARINE. SCA conditions continue through this evening and then gales develop late tonight. Will go ahead and cancel the SCA and convert to gales throughout.
Gales will be in effect across Delaware Bay and Delaware ocean through early Sunday morning, and then a SCA will be needed. For the New Jersey ocean waters, gales continue into Sunday evening. Conditions gradually subside below SCA conditions Sunday night.
Outlook .
Monday . Winds remain below advisory levels during the day Monday.
Monday night-Tuesday . Southwesterly winds will increase, with gusts above 25 kt possible on the southern coastal waters late Monday night. By Tuesday afternoon, an abrupt shift to northwesterly winds is expected and gusts as high as 30 kt are possible on the coastal waters and the Delaware Bay.
Tuesday night and Wednesday . SCA conditions are expected to continue with northwesterly winds gusting as high as 30 kt at times.
Thursday . Winds and seas are expected to slowly subside below SCA criteria during the morning.
PHI WATCHES/WARNINGS/ADVISORIES. PA . None. NJ . None. DE . None. MD . None. MARINE . Gale Warning until 7 PM EST Sunday for ANZ450>453. Gale Warning until 7 AM EST Sunday for ANZ430-431-454-455.
