FORECAST SUMMARY
Monday was the aperitif. The main course arrives later this week. Prepare for a winter week in advance, with plenty of cold and a major winter storm in much of the area later Wednesday through Thursday in the early hours of the morning. If you think it’s been a while since we’ve seen major snow, you’re right! Remember that last winter was one of the least snowy on record, with little snow, let alone a box office storm. The last time there was widespread snowfall in Lehigh Valley and Berks County was far behind on the first day of spring in March 2018. But it is possible that many of us measured at least one foot of snow on Thursday morning.
Monday’s winter mix, which brought a one- or two-inch coating for some, especially at higher elevations, has moved, and cleaning and drying took place last night. Now we will enjoy an “intermediate” event of cold and dry calm, with a good amount of sun and highs in the 30s.
Even on Wednesday it will start to dry out, but expect a very different end as the snow develops later in the day, sometimes it gets windy and heavy on Wednesday night and shrinks early on Thursday. in the morning. Double-digit accumulations are likely to occur in much of the area before the storm leaves, giving way to a cold but dry climate to end the week and start the weekend.
DETAILED FORECAST
TODAY AND TODAY
The high pressure over eastern Canada will provide a partly mostly sunny, cold, dry day between our appetizer and main course. The highs will be in the 30s, as the colder air will set in and set the stage for our mid-week Nor’easter.
This same Canadian maxim will provide a continuous source of cold air during the storm, keeping most of us mostly snow. Look for the clouds to gradually increase tonight, as the lows drop to fairly cold levels in the 1920s.
WEDNESDAY AND WEDNESDAY NIGHT
It will begin to dry out on Wednesday as the clouds thicken, and snow will develop from southwest to northeast during the afternoon. The snow will be light at first, but will quickly become stronger and intense at times, Wednesday evening until most of Wednesday night, before subsiding early Thursday.
Expect the heaviest snow and most accumulations to fall between sunset on Wednesday and sunrise on Thursday, when snow can fall at a rate of several centimeters per hour. The winds will also increase and cause some snow to blow and drift.
The mix will be a factor along the southwest of the Highway 95 corridor through the Delaware Valley and central and southern New Jersey, especially with rain, wind, and tidal flooding toward the coast.
By now, apart from any change in the forecast or intensity of the storm, a heavy generalized snowfall 12 to 18 inches is expected in much of eastern Pennsylvania and northern New Jersey. 8-12 inches An amount of snow is expected in southeastern Pennsylvania, more if there is little or no mixture, less if there is a longer change in rainfall. 4-8 inches there is probably snow near the I-95 corridor from Trenton to the south, and the amounts continue to drop drastically as you continue south through southern New Jersey. When you get to the shore, just wait for a cover at most, as things will rain mostly here.
THURSDAY
The remnants of light snow or snow showers around Thursday sunrise should subside as our coastal storm picks up quickly. A lively northerly breeze will persist, as will many clouds, with some gusts in the afternoon. Temperatures won’t move much, hovering for the low 30s most of the day as cleaning and digging begin. Add the wind and keep the chills below the ice cream all day.
FRIDAY, SATURDAY AND SUNDAY
High pressure increases, winds decrease and seasonal cold air settles during the beginning of the weekend. Don’t expect the snow to melt so quickly, with afternoon highs in the mid-30s and night lows until teenagers thanks to clear skies and a deep layer of snow. On Sunday, a weak cold front will approach from our west increasing the clouds. We’ll get a warmer touch ahead of the front as the highs return to the top 30s close to 40 degrees … more seasonal. The front can cause rain or snow in the late hours of the day or night, but right now we don’t expect it to be a big deal.
