Area Forecast Discussion National Weather Service Mount Holly NJ 513am EST Thu Jan 23 2025 Synopsis Arctic high pressure will remain in place to our west and southwest into the weekend, keeping below normal temperatures and dry conditions in place across the region through Saturday. A weak cold front will pass through on Friday. Southwesterly flow will develop over the weekend, resulting in moderating temperatures by Sunday and into early next week. Another cold front may impact the region into the middle of next week. Near Term - Through Tonight Very cold morning ongoing with lows in the single digits or even negative numbers. The office actually just hit 0! No changes made with the daybreak update. For today, mostly sunny skies are expected with some moderation to the airmass. High pressure moves offshore, fostering in a light southerly flow. Some clouds move through the southern areas as a developing coastal low slides by to the south and east. Temperatures will be in the mid to upper 20s and low 30s, a few degrees warmer than yesterday. For tonight, should see decent radiational conditions again. However, a light west/southwesterly breeze and moderation of the airmass will allow temperatures to be a few degrees warmer than this morning. Lows will range in the upper single digits in the cooler, more sheltered spots, with low to mid teens elsewhere. Short Term - Friday Through Saturday Night Benign weather and below normal temperatures continuing to close out the week and into the weekend, but with some slight improvement in temperatures compared to the frigid week we've experienced. A modestly amplified trough will approach the area Friday and pass through Friday night. Strong zonal flow will then develop in its wake into the weekend. At the surface, a decaying frontal boundary will pass through on Friday with high pressure building in from the west and southwest in its wake. The front will not be very noticeable from a sensible weather perspective, as it will mainly just bring a slight reinforcement of arctic air for another 24 hours into Saturday before temperatures rebound back closer to normal by Sunday. The dynamics aloft, lack of any moisture return, and decaying nature of the front will translate to a dry frontal passage, although a slight increase in cloud cover is anticipated. Can't completely rule out a passing flurry in the Poconos. Temperature wise, Friday should see a slight rebound in temperatures compared to today. Highs mainly in the upper 20s to low 30s. The I- 95 corridor looks to remain at or below freezing though, with only far southern NJ or Delmarva having a meaningful chance of rising a couple degrees above freezing. With the resurgence of arctic air Friday night, we should see a return of more widespread single digit low temperatures, at least northwest of I-95. Fortunately, there won't be much wind to contend with. With this update, kept single digits confined northwest of I-95 and from around 10-15 degrees along and southeast of I-95. Low temperatures Friday night will ultimately depend on the extent of the snowpack, which will probably be getting quite sparse and thinned out near and southeast of I-95. The snowpack is already down to about T-2 inches in this area, and it will probably diminish even more with temperatures near 30 degrees and plenty of sun over the next 2 days. This will be the factor limiting single digits in that region. High temperatures Saturday likely remaining similar to that of Friday with increasing cirrus. For Saturday night, temperatures will finally rebound more considerably, ranging mostly from the upper teens to low 20s. This will be due to surface flow shifting southwesterly and remaining elevated overnight, along with warm advection pushing the arctic airmass north of the area. Still cold (and below normal), but a welcomed improvement to what we've experienced the past few days! Long Term - Sunday Through Wednesday The extended period looks to start with zonal flow aloft across the Northeast, with a closed upper-level low over the Hudson Bay. This feature looks to meander southeast into portions of Quebec through the middle of the week. As it does so, subtle shortwaves will likely pass through our area, particularly Tuesday and beyond. At the surface, high pressure looks to initially be in control with low pressure confined well to our north. There may be a couple of weak frontal passages during the early part of the week, but as of right now it appears they will be dry, with the exception of maybe a few flurries in the Poconos. There is agreement amongst the models that an area of low pressure will develop in the Great Lakes vicinity, passing to our north Tuesday into Wednesday. A trailing cold front could bring increased cloudiness to the region. There is a non-zero chance that a little light rain or snow could accompany this passage as well, though confidence is not high on that front. Temperatures through most of the extended period look to be fairly close to seasonal normals across the area with only minor fluctuations from day-to-day. Marine Sub-SCA (Small Craft Advisory) conditions through tonight are expected. Winds will be around 5-10 kt through today, increasing to around 10-20 kt tonight. Seas 1 to 3 feet. Some light freezing spray is possible on the outer waters with the increase in winds tonight. Outlook... Friday through Monday No marine hazards anticipated. Winds remain around 10-20 kts and seas 2-4 feet. A chance of some light freezing spray Friday morning. We should see a reduction in ice coverage into the weekend and early next week as temperatures begin to moderate compared to this past week.
