Temperatures across the region tonight are plunging below the freezing mark. As a result, the melting snow and ice will refreeze on untreated surfaces. Unfortunately, the sunshine we saw today was limited by the clouds and several trees have retained quite a bit of snow and ice. More problems tonight can be expected with falling trees, especially with holly trees and pine trees.
A clipper will move through our region on Friday. Is system is located near Cleveland and Detroit. This will drive down to our south. This system will produce areas of snow showers or even a period of light snow. Temperatures will be around or just above freezing during the daytime hours, but the ground is cold enough, especially with snow-cover for there to be an additional coating of snowfall across the region. Some spots could even squeeze out an inch of snow. This system is unfortunately timed for the afternoon into the evening commute. Another clipper will move in for Saturday and that also has the potential to bring some more light snowfall to the area with very light accumulations of a coating to an inch. We may not see all snow along the coast. In addition, southern areas could escape the snow on Saturday as the best dynamics from the second event seem to target Northern and Central New Jersey.
This snowfall is not much, but the previous events this year with this nuisance snowfall have caused major headaches. One inch or less of snow will not keep people off the roadways and that is how we get more accidents and jams during these types of events. Since these coatings may not be uniform, I will put out a graphic highlighting the potential for periods of snow.
Sunday and Monday will be dry and will give us a break (brief) from the wintry weather. The snow on the ground will not be going anywhere as we may see temperatures only slightly above freezing.
Another middle of the week storm appears at the end of my five day forecast. At this point and time, some snow could begin Tuesday Night. I think the bulk of this storm will be on Wednesday…possibly extending into Thursday. The details of this storm are unclear as it is too far out. The models seem to indicate some wintry mix or more snow. Over the course of the next few days, we will see this storm bounce all over the place on the models and even disappear at times. The overall pattern in the end looks favorable for a winter storm.
The Wednesday snowstorm was another significant snowfall for the record books. For New York City it was the most single snow in January. In Philadelphia, it was the third biggest single snow in January. The amount of thunderstorms with system was impressive and rare. Strong upward-vertical motion produced the thundersnow and thundersleet. A strong thunderstorm off the coastline of Monmouth and Ocean Counties produced hail along the coastline in those counties as reported by trained weather spotters. That storm also exhibited some weak upper-level rotation on the radar imagery. Thunderstorms in the summer can drop one to two inches of rain, or more, in a period of time. Some were surprised by the impressive snowfall rates exceeding three inches per hour. It is the same concept in the winter, producing heavy precipitation amounts in a short period of time. So even with the ice and rain in the early evening hours, many quickly accumulated substantial snowfall accumulations. Snowfall ranged from 9 to 20 inches across the state with the highest amounts in Western New Jersey into Northern and Central New Jersey. The coastal areas saw less, particularly the southeast. This is because the center of the energy pivoted across Delaware and Cape May allowing for a dry slot to build in after temperatures cooled here.
