MLK Weekend Winter Storm

The Winter Storm Threat for this weekend is growing but how close will the Rain/Snow line come to the Philadelphia area? Will it be all snow/rain, will we have a blizzard?

Our team is monitoring the track and models for the Sunday into Monday Winter Storm. At this point we are still in “threat” mode as the threat is there but for who? The models have been going back and forth and we are hoping to see more agreement either today or tomorrow.
Here is the latest GFS that just ran this morning. Some areas could see a lot of snow, some will see snow to rain and some will see rain. At this point it appears we will see some snow on Sunday afternoon then a wintery mix/rain on Monday but again this can and will change over the next few days.

The Euro above shows interior PA getting CRUSHED while areas along i95 are mix/rain.

The 06z GFS is NOT a forecast from us, we are just showing the latest model run for this storm.



Here is a guide that we tend to follow with winter storms to bring you the latest information. 7-10 Days out – Pattern Recognition and watching for THREATS 5-7 days out- Paying close attention to TRENDS3 days out- Timing and precip type detailed out 1-2 days out- final calls, detailed timing, nowcasting.
Updates will come throughout the next few days, and a full detailed post will come as early as late tomorrow/Friday.

Winter Storm Update Final Snow CALL

A winter storm will blanket the area with 3-5″ of snow late tonight into the early morning. Friday morning commute will be a mess. If you can stay home please do so and allow the snow plow operators time to clear the road without vehicles on the road.


WINTER WEATHER ADVISORY REMAINS IN EFFECT FROM 10 PM THIS
EVENING TO 10 AM EST FRIDAY...

* WHAT...Snow expected. Total snow accumulations of 3 to 5
  inches.

* WHERE...Central and southwestern New Jersey, southeastern
  Pennsylvania, northeast Maryland and central and northern
  Delaware.

* WHEN...From 10 PM this evening to 10 AM EST Friday.

* IMPACTS...Plan on slippery road conditions. The hazardous
  conditions could impact the morning commute.

* ADDITIONAL DETAILS...A narrow band of heavy snow may result in
  a brief period of snow rates up to 2 inches per hour late
  overnight and locally higher snow totals, though where this
  band may set up is uncertain.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Slow down and use caution while traveling.

SNOWFALL TOTALS:
Along i95 and in the Philly Metro area a general 3-5″ of snow is projected with some areas getting close to 6″ depending on banding setting up. The latest NWS map is attached below as well. Between 3 and 5 inches is currently expected along much of the Interstate 95 corridor from New York City to Philadelphia and Washington..

Winter Car Survival Kit.
If you are going to be traveling during the height of the storm, have the following in your vehicle in the event you get stranded.

A kit with essential items can help keep you warm while stranded, so make sure your vehicle is packed with these things before you hit the road:

  • Food: such as snacks such as protein bars, nuts, dried fruit, whole-grain pretzels and crackers.
  • Water
    Warm extra clothes: Scarves, mittens, socks and hats. If you’re not wearing the warmest shoes (say, sandals or Crocs), you might also want to throw in a pair of snow boots.
  • Blankets: When you can’t rely on your car’s heater to keep you warm, you can prevent hypothermia by having blankets to keep your body temperature up. Make sure to have enough for yourself and any other passengers.
  • Hand warmers, small candles and matches: Keep toasty when rationing fuel.
  • A flashlight with spare batteries: With daylight being much shorter during winter, there’s a good chance that you may find yourself stranded in the dark. If your car breaks down and there are no inside or outside lights, a flashlight can be an important tool.
  • Whistle, flares, red bandanna or bright cloth: You can signal for help with these items.
  • Phone charger: Whether you’re snowed in, you crash or your car breaks down — especially in a low-traffic area — a fully charged phone is a must. Opt for a cellphone adapter to plug into the lighter or, even better, a USB portable battery pack (charge it fully before departing.)
  • Shovel and cat litter: When your car gets stuck in the snow, digging it out might be the way to go. With a portable snow shovel, you can dig around each wheel. Sprinkling cat litter — or sand — can add traction to get things moving again.
  • Ice scraper: Snow and ice can impede visibility. Make sure you clear off every inch of your vehicle before hitting the road and after any storm.
  • Jumper cables: Cold weather can be hard on a car. If your battery fails, having your own set of jumper cables could save you an expensive tow.
  • Personal hygiene items: Taking care of hygiene inside a car is challenging, but you can keep moist towelettes, period products, garbage bags and plastic ties — to seal any waste — for sanitation. If you wear contacts, have lenses and solution ready. You may want to throw in a travel-size toothbrush and toothpaste kit.
  • Medication: If you take prescription medication, have at least enough stored for a 72-hour emergency.
  • Supplies for pets, babies and children: If you’re traveling with animals and children, make sure you have enough supplies for their needs. Include pet food, diapers, infant formula, bottles, wipes and diaper rash cream. To keep small children entertained, stash paper, crayons, books and toys.
