WINTER STORM WARNING FOR PARTS OF THE AREA
Winter Storm Warning goes into effect tonight at midnight for York, Lancaster and Adams counties. This is an area that may see a bulls-eye for higher snow accumulation. Low pressure approaches from the west and will be a slow moving system so it will be a long duration snow event. An area of low pressure will develop along the Mid-Atlantic coast. The development of this system will enhance snow accumulations in the warning area. A Snow accumulation of 4 to 8’ is possible for the counties in the warning. The low is key, so if it develops closer to the coast, it will shift the heavy snow band west. If it develops farther east, then the heavy snow band shifts east. It will develop early Tuesday morning and quickly race towards the northeast. The rest of the area is under a WINTER WEATHER ADVISORY from midnight tonight until 5am Wednesday. Snow accumulations of 2 to 5” will be possible.
Rain and snow showers will develop this afternoon and will transition to all snow late this evening. The upper low will be very low to move out of the Great Lakes through the day. Small disturbances will rotate through it, producing snow bands, which will rotate through the area. This is when you can expect the most intense snow to fall.
FRIGID PUNCH FOR VALENTINE’S WEEKEND
The coldest air of this winter season will arrive for Valentine’s weekend. Morning lows in the single digits, possibly below zero, and high temperatures in the teens. Wind chills will run well below zero with the gusty winds projected. Be prepared for a very cold couple of days.
