Temperatures just prior to daybreak plummeted to the negative single numbers and negative teens inland to the positive single numbers along the coast. The combination of frigid temperatures and northwest winds between 15 and 25 mph with some higher gusts was creating dangerously cold wind chills. Wind chill readings were as cold as minus 30° over interior southern New England with widespread minus 15 to minus 25° wind chills elsewhere. Despite abundant sunshine, the mercury will be nearly unresponsive today. High temperatures will range from the negative single digits inland to the single numbers and some lower teens along the coast. Clouds will increase late this afternoon as low pressure over the Great Lakes tracks across the Ohio valley. Low pressure will head for the mid Atlantic coast late tonight, causing clouds to gradually lower and thicken. Light snow will develop along and south of the Mass Pike late this evening then continue overnight. The air will probably be to dry for snow to reach the ground over northern Massachusetts and southwest New Hampshire. Lows will range from the negative single numbers inland to the positive single numbers near the coast. Low pressure will track well south of New England Thursday afternoon then head out to sea Thursday night. Light snow will taper to scattered snow showers and flurries during the afternoon. The exception will be across Cape Cod and Nantucket where accumulating ocean effect snow will occur. Much colder and drier air will be ushered behind the departing low. Dangerously cold wind chills will occur again Thursday night and Friday. === === === ORH Terminal Aerodrome Forecast issued 14-Jan-2004 06:23 EST === 7am: 30014g22kt P6sm Sct250 4pm: 29012kt P6sm Bkn110 10pm: 28008kt 5sm -shsn Br Ovc070 3am: 36005kt 3sm -sn Br Bkn035 Ovc060
