Weather for New Year’s Eve and Day

After a cold start – this morning’s low temperature was 19 degrees (F) at the UMW weather station – the last day of 2012 will bring a southwest flow both at the surface and in the upper levels as the region sits on the northern edge of a high pressure system centered over Florida.  This wind direction will both warm things up (today’s high will top out in the upper 40′s) and bring in a thickening cloud deck as the day wears on.   The good news for New Year’s Eve revelers is two-fold:  there won’t be any precipitation to mar the midnight celebration and the clouds will keep temperatures somewhat milder than this morning’s lows, with the projection for midnight’s air temperature to be in the upper 30′s with light winds.

By dawn on New Year’s Day, however, there will be a good chance of light precipitation that could begin as mixed rain and snow before turning to all rain later in the morning.  The total amount of available moisture is relatively small but the chance for more mixed rain and snow reenters the picture Tuesday night until the faucet shuts off by about midnight.  High temperatures on New Year’s Day will climb into the mid-40′s ahead of the next cold air mass that will drop temperatures for the rest of the work week.  And as for that potential storm system later in the week?  It now appears that the northern and southern parts will not join forces (“phase”) so the ‘Burg will likely only see clouds on Thursday, altho’ I wouldn’t rule out a stray shower or snow flurry.

Happy New Year!!!! (And be safe!)
