And now for the bitter cold...

It was 59 F on Monday, colder on Tuesday, and snowed on Wednesday...so it's only natural that it turn bitterly cold to complete the "spring tease to winter-to-yo-face" slide. (P.S. No one, not even the die hard skiers, were happier it ended up snowing on Wednesday than yours truly. I put out the most arrogant tweet in the history of weather on Monday night and then lost several hours of sleep as the computer models flip flopped. But, as Herm Edwards would say, "You play to win the game!")

Today: An arctic cold front is pushing through the state producing some snow squall activity. For the most part, however, the organized squall line has fallen apart as it pushed down into the coastal plain. So for the rest of the afternoon look for a few scattered bursts of snow closer to coast, but many locations remain dry with a mixture of sun and clouds. High temperatures are already in the upper 30s across southern Maine, but temperatures will be falling by late afternoon.

Tonight: The arctic air associated with today's front will sink in this evening. Look for partly cloudy conditions and bitterly cold temperatures. Lows will be in the single digits along the coastline, 0 to -5 across the interior and -15 to -20 in the mountains. A brisk west wind won't help matters making for dangerous windchills in the mountains.

Friday: There could be a few clouds hanging along the coastline in the morning as a storm passes to our south, but otherwise look for mostly sunny skies and cold temperatures. Highs will have a hard time getting out of the single digits in the mountains with even the coastline likely staying in the 15-19 F range.

A warm front will slink into the state on Saturday and provide some sneaky light snow for central and northern Maine. See, as the boundary pushes through it will create what we call "overrunning snow" which is when snow is created by warm air at the mid levels pushing over the top of cold air at the surface. Look for periods of light snow to develop in the morning over southern Maine with the brunt pushing into the Midcoast and Downeast by noon. It doesn't look like a big deal by any stretch, but I wouldn't be shocked to see a widespread coating with accumulations up to 3" along the Midcoast and Downeast.

After a quiet Sunday another arctic shot of air moves in for Monday/Tuesday/Wednesday. This shot actually looks a bit colder than what we will experience tonight/Friday with highs struggling into the teens.

Big Picture: Our overall pattern looks polar jet stream dominated. That should provide below average temperatures, but also below average precipitation. My snow loving weather weenie friends are trying to find a way around the "below average precipitation", but I don't see any compelling argument at the moment.
