Fwd:

    Winds out of the south allow mild temperatures today but plenty of moisture rides up the Atlantic Coast  Monday into Tuesday. Cloud cover will increase this evening. Low pressure center will combine with a second weaker low arriving from the Gulf. These systems will pass close enough Tuesday to toss some mixed precip in our direction tonight into Tuesday.  A few light flurries are possible late tonight/early Tuesday morning. Freezing rain is also a possibility, especially for eastern portions of West Virginia. Any snow/freezing rain will be short lived as warm air advances northward, quickly changing precip over to rain by mid morning Tuesday. Warm air will mix in to bring temperatures into the mid 40s Tuesday afternoon.
    Low pressure will continue its northeasterly trek up the Atlantic Coast. However cold air on the back side of the front will bring temps back down to around freezing Tuesday night. Precip will change over to snow and may linger into Wednesday. Accumulation will depend on the timing of cold air filling in behind the front-could be more if cold air arrives faster. Consensus is to go with minimal accumulation around 1" even in higher elevations. Seasonal temperatures & generally dry conditions are expected for the remainder of Wednesday & Thursday. Another low pressure wave will swing down from Canada, bringing more winter weather and colder temperatures early Friday.
