Discussion

Let’s take a look back before we look ahead to this week’s weather. First of all, 2011 will go down as the wettest year ever in Philly with 64.33” of rainfall (normal is close to 40”). Also, December will go down as the 5th warmest ever with temperatures averaging about 5.5 degrees above normal. Now for today, winds will increase to 20-30 mph behind a strong cold frontal passage, and then an Arctic front will pass through tonight and that will open the flood gates for the first invasion of Arctic air into the Mid-Atlantic this season. The big weather story at this afternoon’s outdoor hockey game in South Philly between the Flyers and Rangers will be the strong winds gusting up to 20 to 25 mph as temperatures hold steady or even drop slowly into the 30’s. Tuesday promises to be a brutal day throughout the Mid-Atlantic region with temperatures likely not even able to reach 30 degrees and wind chills will be considerably lower. Wednesday will also be very cold, but the Arctic air will retreat by the time we reach Friday and Saturday. Longer range, there is the potential for a storm to deal with early to middle part of next week somewhere along the east coast. Additionally, other Arctic blasts are destined to reach our area during the second and third weeks of January.
