TUESDAY NIGHT: : Rain and snow developing this evening, changing to snow late. Roads may become slippery late. Low: 32
WEDNESDAY: Blustery with snow, some heavy, creating difficult travel. 6-12” for much of the area with locally higher amounts. 3-6” far west and less toward the shore. High: 35
WEDNESDAY NIGHT: A leftover snow shower or two in the evening; otherwise, mostly cloudy and brisk. Low: 29
Ready or not, here we go again. For the second time in less than a week, a strong coastal storm will deliver a harsh reminder that it is still indeed winter, at least for another two weeks. While the strong and damaging winds were the most notable aspect of last Friday's storm, the winds will not be as strong with the latest storm. The snow, however, will be heavier and more widespread.
Clouds will continue to thicken Tuesday evening, with a light mix of rain and snow developing across the area from west to east. Given the milder temperatures in place initially, don't be surprised for it to likely be predominantly rain, at least before midnight, for many of us.
As the colder air becomes more established, expect any rain to change to all snow overnight, and some light accumulations are expected by sunrise Wednesday. Temperatures will drop to the low-30s, and winds will remain fairly light overnight, although that will change come Wednesday.
The crux of the storm will occur Wednesday in terms of both snow and wind, with periods of snow, some heavy at times, pretty much from sunrise to sunset. The heaviest snow is most likely to occur from mid-morning through mid- to late-afternoon on Wednesday, with some bands of very heavy snow, with snowfall rates of 1 to 2 inches per hour, likely setting up across parts of far eastern Pennsylvania and much of northern New Jersey.
Winds will increase as well, but not to the level of the intense 60 mile-per-hour gusts we had last week. This time, winds will blow briskly from the northeast, sustained up to 20 miles per hour and gusting at times to 30 to 40 miles per hour. The combination of the blustery winds and the heavy and wet snow accumulating on power lines and trees (some weakened by last week's storm) means that additional power outages and tree damage are both possible.
All of eastern Pennsylvania and northern New Jersey is under a winter storm warning through Wednesday for the likelihood of at least six inches of snow. In fact, our snowfall forecast calls for a widespread 6 to 12 inches of snow from north and west of the Interstate 95 corridor through most of eastern Pennsylvania, including the Lehigh Valley and the Poconos, as well as all of North Jersey. Within that large area, there will likely be a swath of locally more than 12 inches of snow, especially where those heavier snow bands set up shop for a few hours.
The heavier snows will also extend west into Berks, Schuylkill, and eastern sections of Lancaster and Lebanon counties, where at least six inches of snow is likely. Farther west from there, amounts will diminish, perhaps rather sharply. South and east of the I-95 corridor, rain and sleet are expected to factor in for a longer time and therefore, less snow is expected, with 3-6" across interior southern New Jersey, just southeast of Interstate 95, and 1-3" southeast from there, with perhaps very little along the shore. Winter weather advisories are in effect for southwestern New Jersey and northern Delaware due to the rain/snow line uncertainty.
Snow should end from southwest to northeast early Wednesday evening, with winds still blowing briskly Wednesday night and shifting from the northwest behind our departing storm.
Thursday and Friday look largely dry, rather breezy with west-northwest breezes continuing, and a little chilly for early March, with temperatures in the upper 30s. Our average high for this time of year is in the mid-40s, so we'll be running below that with a brisk breeze adding an extra chill. A stray snow shower or two can’t be ruled out late Thursday or anytime on Friday, but no accumulation is currently expected.
The second weekend of March looks nice with cool sunshine on Saturday and then some increasing clouds on Sunday. Another ocean storm is expected to develop on Monday, but latest indications are that it may stay safely to our south and east and slide out to sea underneath us. A chance of rain and snow is kept in the forecast just in case late Sunday and early Monday, but hopefully that can be taken out if these southerly trends continue with this next storm. The cool pattern looks to remain indefinitely through at least the first half of next week.
