Winter Storm to Bring Widespread Snow Sunday

A winter storm is set to impact Pennsylvania on Sunday, with some areas expecting over a half foot of snow. Snow will start in the southwestern part of the Commonwealth during the morning, increasing in intensity throughout the early afternoon hours as the storm continues to move northeast. Intense snowfall rates are likely east of the Interstate 99 corridor during the mid afternoon hours, which will create travel impacts across the Philadelphia, Harrisburg, and Scranton/Wilkes-Barre metropolitan areas. Philadelphia could see a brief changeover to sleet between 3pm and 6pm, which will lower snowfall totals across areas of the southern Delaware River Valley. Northeastern Pennsylvania is expected to receive the most snowfall, with upwards of a half foot likely after this storm system is all set and done.

Snow is expected to wind down across the Commonwealth overnight Sunday into Monday morning, with Lake Effect snow possible in Northwest Pennsylvania throughout the afternoon hours on Monday. This snowfall will be here to stay as we head into the next work week, as an arctic air mass will move in behind this system. Temperatures across the state are expected to drop below zero as you wake up for your Tuesday and Wednesday commutes. Wind chill temperatures across western Pennsylvania could drop as low as 30 degrees below zero Wednesday morning.

After a quick hitting snowfall throughout the day on Thursday, plenty of melting occurred on Friday, as temperatures peaked into the mid 30s to low 40s across the Commonwealth. Although many of these high temperatures were close to seasonal averages for this time of the year, conditions felt much more mild compared to the cold beginning of the week. Pleasant conditions were felt across much of the state, as early morning clouds subsided and gave way to more sunshine in the afternoon.

A pleasant day on Friday will be followed up by sloppy conditions on Saturday, as our next weather maker moves in, spreading a wintry mix across the Commonwealth. Snow will spread across the northwest region of the state from west to east during the morning hours. Although not much accumulation is expected, some spots may become slick. Precipitation will spread across the southwestern portion of the state, where up to a quarter of an inch of rain is expected with some snowflakes mixing into the higher elevations. The eastern half of the state can expect sprinkles of rain and some occasional flurries in the Poconos.

As the latter half of Martin Luther King Weekend arrives, we are watching a potential coastal snowmaker, with a widespread plowable snowfall likely across eastern Pennsylvania. Depending on the position of this system off the coast, some areas of central Pennsylvania may tap into the snowfall, with the western third of the state likely to remain dry. Following this snowmaker, an arctic air mass will drop temperatures into the single digits after the Monday holiday, with wind chill temperatures for the middle of next week dropping as low as 30 degrees below 0.

Hurricane Milton – October 9, 2024

As Hurricane Milton barrels towards Florida as a Category 5 storm, some residents are evacuating while others brace for the impact of yet another hurricane. Only two weeks after Hurricane Helene, resources are already stretched thin. With maximum sustained winds around 145 miles per hour and wind gusts upwards of 170 miles per hour (as of 11 am on 10/9), Hurricane Milton looks to slightly weaken as it approaches landfall.

Local Severe Weather Event, Monday June 26th

Created by: Ben Tomfohrde, Kaitlyn Potucek, Denys Khrulov

Synopsis

A rather robust setup will be impacting our region early this week, which will spark the potential for severe weather. Multiple low pressure systems will develop along a stationary front across the Great Lakes region. A low pressure system that will develop over Michigan and surrounding areas will be the one we will be closely watching. A cold front will stem from it, which may become occluded closer to the low, which will force for thunderstorms to develop across the region. Additionally, a surface trough east of the Appalachian Mountains will serve as another focal point for thunderstorm development.

Tropical Storm Bret, June 22, 2023

Tropical Storm Bret

The second named storm in the 2023 Atlantic hurricane season is currently forecast to impact the Lesser Antilles Thursday night into Friday. Abnormally warm waters have allowed Bret to strengthen into a strong tropical storm. It is currently moving west at about 14 mph and has maximum sustained winds of 65 mph with stronger gusts. Bret’s intensity is not likely to change much before it impacts the Lesser Antilles, but shortly after it enters the Caribbean it is expected to weaken. Strong wind shear in the atmosphere will tear the storm apart as it tracks towards Mexico. Bret is not forecast to impact the United States.
