THE ARCTIC AIR MASS THAT BROUGHT RECORD COLD TO THE MID-ATLANTIC STATES MOVES OFF THE COAST… A FRONTAL SYSTEM MAY BRING SOME RAIN LATE SATURDAY NIGHT INTO SUNDAY… RAIN AND MILDER TEMPERATURES SHOULD MELT A LOT OF THE SNOW AND ICE

We’re going to get a break from the bitter cold temperatures that we’ve endured the past few days. Record low temperatures were recorded in numerous locations in the Eastern part of the country. I think one of the most notable record low temperatures was the one from Lynchburg, VA, where it bottomed out at minus 11 degrees! That was their all-time record low temperature for any time of the year! Norfolk, VA had a record low of 9 degrees. Today (Saturday), we’ll see temperatures rise into the 40’s, which will begin the melting process. However, clouds will be slowly increasing as a frontal system approaches the region. If you are traveling to western VA, be prepared to encounter some wintry precipitation today. A low pressure system will drag a warm front through our region later tonight and Sunday. This should produce some rain later tonight along with fog in some areas. The cold ground along with the snow/ice cover will enhance the formation of fog. Believe it or not, temperatures may actually rise overnight Saturday night. Rain should continue on Sunday possibly tapering off later in the day. Another cold air mass will be moving into our region on Monday bringing well below normal temperatures. The week ahead looks like a chilly one for the most part. Why are we receiving such cold temperatures lately? The jet stream, that river of strong winds that steers weather systems, is to blame. It has been diving down from the Polar region into the Eastern part of the nation. Note that in the Western States all the way up through Alaska, temperatures recently have been much above normal. Note that many times when we have below normal temperatures during the winter, the west coast is warmer than normal and is also usually dry. This is not good news for those folks out there, where a very persistent long-term drought exists. The snow pack in the Rocky Mountains provides needed water for many locations and it is running much below normal. That’s it for now. Have a great weekend!
