SOUTH JERSEY WEATHER CENTRAL IS IN STORM ALERT FOR 12"+ OF SNOW.
WINTER STORM WARNING IN EFFECT FOR ALL COUNTIES FROM 1AM SATURDAY TO 6AM SUNDAY.
COASTAL FLOOD ADVISORY & HIGH SURF ADVISORY IN EFFECT TONIGHT AND TOMORROW.
Here is an update to my previous forecast along with a snow map.
A nor'easter will move up the coast. It will interact with upper level energy off the NJ/DE coast and produce heavy snow and windy conditions along with other coastal problems. The heaviest snow will fall Saturday evening and night. Thundersnow with snow accumulating 1-2" per hour is possible Saturday evening. We're done with the models it is time for nowcasting!! If you check radar you can see precip is coming close to South Jersey. Some is not reaching the ground, but it is farther north than expected. That's why I moved the starting time up a little.

ACCUMULATIONS
Here is my snow map. The immediate shore may have some mixing as mentioned above in the timeline Saturday afternoon but still should get around 8-12". West of that expect all snow with amounts around 12-16" with isolated higher amounts. All areas will have higher drifts due to blowing snow. This may change slightly so please stay tuned.
OTHER PROBLEMS
Due to the storm predicted to stall off the coast it will create high seas, above normal tides, and strong winds. Winds will be sustained to around 20mph inland to 30mph along the coast with gusts up to 50mph. This will cause the blowing and drifting of snow which will cause low visibilities tomorrow. Drifts will be highest along fences, houses, and cars. There will be some moderate beach erosion as the low slowly moves past us to our east. There will also be some minor tidal flooding Saturday morning at times of high tide.
TRAVEL PROBLEMS
Try to hold off on traveling Saturday and Saturday night. Snow will be falling fast so plows will have a tough time catching up. Also, plows may not get to side streets in some towns due to it being a weekend. Please use caution. There may also be some travel problems Sunday morning but most main roads should be clear by then.
