Pre-dawn temperatures ranged from the single digits over the normally colder valleys in southern New Hampshire and northwest Massachusetts, to the 20s along the coastal plain. Winds prevailed from a light southeasterly direction. A fast moving low pressure system will bring a variety of precipitation to the area this afternoon and tonight. Snow will spread across western Massachusetts and northeast Connecticut this afternoon, and reach coastal sections toward evening. Initially, most of the precipitation will be in the form of snow, with the exception being along the immediate south coast, Cape Cod, and the outer islands, where it should be warm enough to produce rain. Warmer air will quickly come up from the south, as well as off the Atlantic ocean, and change the snow to rain over coastal Massachusetts and Rhode Island. Snow accumulations in this region will generally be less than 1". Over the interior of central western Massachusetts, portions of northeast Connecticut and southern New Hampshire, 2 to 5" of snow may accumulate. The snow will come down very hard for a few hours. Visibilities will drop to around one quarter of a mile and roads will become snow packed. A winter weather advisory has been issued from late this afternoon into the evening hours. Snow will then change to freezing rain or rain, before ending around midnight. Partial clearing will take place on Wednesday, and a rather mild start will allow temperatures to reach into the low to mid 40s. A cold front will move through the region around sunset, and may bring with it a few snow flurries. Otherwise, colder air will make its way back into the region Wednesday night and Thursday. A complex storm system will approach the region on Friday. This will have the potential to bring a significant amount of snow, ice and rain Friday into Saturday. === === === ORH Terminal Aerodrome Forecast issued 3-Feb-2004 06:24 EST === 7am: 22005kt P6sm Ovc008; Tempo 7-10am: Sct015 10am: 12009kt P6sm Bkn010 5pm: 12011kt 1sm -sn Br Ovc008; Tempo 5-8pm: 1/4sm +sn Fg Ovc002 8pm: 10010kt 3sm Fzra Br Ovc008; Tempo 8-0am: 1/2sm Fzra Fg Ovc002 0am: 25015g25kt P6sm Bkn020
