SYNOPSIS. Deep low pressure will continue to move north over eastern Canada through today while high pressure builds in to our south and west. This high will move over the region tonight before moving off to the 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 as the next low pressure system may approach by this time.
NEAR TERM /THROUGH TONIGHT/. A tight pressure gradient remains across the area in between a strong low pressure over eastern Canada and High pressure across the Upper Mississippi Valley. This is keeping a steady west to northwest flow across the area. Now that daytime mixing has begun, stronger winds from aloft will again begin mixing down to the surface. Wind gusts of 25-35 mph, with occasional gusty of 35-45 mph will be possible across portions of the Poconos.
Embedded within this west to northwest flow a weak surface trough will move across the area through today. Meanwhile, a short wave/vorticity impulse will move across the area as well. There is some moisture being trapped underneath the inversion which is keeping partly to mostly cloudy skies across much of the area. There could be enough lift with the short wave/vorticity impulse to interact moisture and squeeze out a few sprinkles, or flurries in the Poconos, into this afternoon. Any precipitation would be light and not amount to much.
For tonight, winds will diminish quickly early this evening both due to the diurnal cycle as well as a weakening pressure gradient as high pressure moves in from the west. Skies will clear for a time as the high builds over the area but by later tonight mid and high clouds will increase ahead of the next approaching system. Nevertheless, still expect that with a period of mainly clear skies and diminishing winds this evening along with low dew points that lows should dip into the 20s to low 30s setting the stage for our next system. Most of the precip with this system will hold off until the day Monday but by late tonight there could be some light mixed precip developing over the Delmarva into southern NJ with the leading edge of light snow nearing SE PA.
SHORT TERM /MONDAY THROUGH TUESDAY/. Complex winter-weather event will unfold during this period, which may come in two fairly distinct phases. The first will occur on Monday as a surface low organizes in the southern U.S. with a strengthening baroclinic zone stretching east-northeast to the Mid- Atlantic. As the low intensifies in the right-rear quadrant of a 140+ kt 250-mb jet streak positioned from the Ohio Valley to southern New England, sustained warm advection will occur on the upstream side of a broad surface high encompassing much of the western Atlantic into New England. Precipitation will spread eastward into the northern Mid-Atlantic through the day as the strength of the isentropic lift increases, but models are disagreeing with the exact placement of the baroclinic zone and the speed with which the precipitation saturates the antecedent low- level (dry) air. The trend has been for a more southern position of the baroclinic zone (which also agrees with model errors with the system so far well to our west), so have spread higher PoPs into our area farther to the south on Monday (and have lowered them a bit farther to the north). I also am suspicious the higher-resolution output is too quick to saturate the low levels. Precipitation may not become substantive until after the Monday morning rush. Additionally, the precip will have a difficult time moving northward given the closer proximity to the surface high and farther distance from the strongest isentropic lift, suggesting areas north of the I- 78 corridor may struggle to see precipitation for a lengthy portion of the day.
The low-level thermal profiles will be favorable for snow north of the baroclinic zone at onset. However, the higher QPF may be just south of the freezing line, which will likely limit snow totals to some degree (as well as the residual effects of the retreating surface high). Finally, the timing of the event is not particularly favorable for higher snow totals (as temperatures will diurnally warm, aided by continued warm advection). Most model guidance is suggesting snow will generally be a couple inches or less in most of the area.
One of the most difficult aspects to this first portion of the event will be surface temperatures. The models are in their usual camps (NAM on the cold side; GFS/CMC warmer). The ECMWF is siding with the NAM, which tends to perform better in these types of events. I weighted the forecast on the cold side, with a much slower transition to liquid precipitation for much of the area. Could see some sleet and freezing rain mix in with the rain and snow, as the low-level thermal profile will be hovering near the freezing mark as surface temperatures slowly warm. This precipitation transition will creep northward through the day, perhaps near or just north of Philadelphia by late in the day.
Phase two of the event takes over Monday night and Tuesday, perhaps separated by a relative lull in precipitation (during the afternoon/early evening). During this phase of the event, a warm nose will develop around 800 mb (aided by a synoptically enhanced low-level jet). As isentropic lift continues to increase in advance of the surface low lifting northeast through the Tennessee Valley and Appalachians overnight, precipitation will increase once again. The near-surface air will warm more slowly than aloft, likely allowing for a period of sleet and freezing rain generally north and west of the I-276/I-195 corridors. Any remaining snow in the Poconos and northern New Jersey will slowly transition to freezing rain and sleet as well. Models are quite varied in timing the transition from south to north (and the speed of the warming in general), but the setup appears conducive for a period of icing in this general region Monday night, perhaps lingering into Tuesday morning north of the I-78 corridor. Some of the ECMWF and SREF ensemble members have substantial ice accumulations in the northern third to half of the CWA. However, other members have little or nothing, with the warmer guidance suggesting the near-surface air is scoured relatively quickly after the warm nose develops. A tough forecast, to be sure.
Currently, expect ice totals of a trace to a few hundredths near the I-76 corridor and a tenth or two north of the I-195/I-276 corridors. Uncertainty is high, as freezing rain will likely mix with snow/sleet during the transition period, and surface temperatures may warm more quickly than forecast (i.e., the window for icing would be cut short). Totals may not be much higher in the southern Poconos and northwest New Jersey, as more of the precipitation may occur as snow/sleet, and the highest precipitation totals may occur farther to the south.
Temperatures will continue to warm on Tuesday, with the transition to plain rain creeping northward to the higher elevations of the Poconos by afternoon. However, as the surface low moves offshore, colder air will filter into the area from the north and west, with precipitation type likely returning to snow late in the day in the northern CWA. That is, if the precipitation does not taper off first (a distinct possibility). For the rest of the area, precipitation should have ended well in advance of sub-freezing temperatures.
One thing to watch Tuesday afternoon into the long term is the winds. If icing is substantial in the northern CWA, the stronger northwest winds in the wake of the system may be effective in downing some tree limbs and power lines.
LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/. Precipitation should be to the north/east of the area by Tuesday night as the surface low progresses to the northwest Atlantic. However, a strong/digging trough will quickly move into the Northeast on Wednesday, allowing for some snow showers in the Poconos and vicinity. The ambient environment is favorable for snow squalls in much of the CWA, as model soundings show a well-mixed boundary layer with nearly saturated parcels at the capping inversion with non-zero CAPE. However, not sold on this potential yet outside of the far north/west (given more consistent model output to our north, in closer proximity to the strongest large- scale lift). For now, have left mention of this potential out of the forecast, pending more consistent model support.
Main concern for the end of the week will be the much colder temperatures. With strong winds looking likely Wednesday and lingering into Wednesday night, wind chills will fall into teens and twenties during the day and in the single digits and teens Wednesday night and Thursday morning (likely sub-zero in the Poconos).
High pressure will build into the region to close the week, with continued cold temperatures but dry conditions. Models are suggesting the development of a coastal low next weekend, but this is approaching la-la-land in model world. Obviously, we will monitor this potential in the coming days.
