 Winter storm warnings are now posted for the foothills of Maine as well as the mountains.  As you head towards the coast, winter weather advisories are posted for a mixed bag of precipitation on the way.  Along the immediate coast, from about Bath southward, there are not advisories for winter weather as the bulk of the storm will be in the form of rain.  That said, there will be some accumulating snow as the storm ends Thursday and advisories may still be needed along the coast.


The track of the storm for tomorrow will hug the coast.  This track pulls warm air at high levels of the atmosphere and also brings warm air into the surface layers here at the ground.  What this means is it will be too warm to snow along the coast, at least for a good chunk of the storm.

Most of you have heard about the storm for midweek and it’s still on track.  Before it gets here we have a couple of mainly dry days with a mild one for tomorrow.

Today will see any clouds clear away and there will be a mix of sunshine and clouds. Highs will surpass freezing in much of southern Maine and make it into the upper 20s in ski country.

Overnight a weak system passes through the region. This will bring a period of snow showers, mostly after midnight. The snow will also end around or even before dawn Tuesday. Accumulation will be light with a coating to an inch or two possible. An isolated 3-inch total could show up in the hillier terrain, but this isn’t a big deal.

 I got an email from my Aunt this afternoon showing her and her husband with my parents learning about snowshoeing.  I was thinking, if there was ever a perfect March day to learn how to snowshoe, ski and skate or anything else outside, this was it.

The snow became a bit soft this afternoon in the stronger March sunshine as the après-ski season began in earnest.   While I was walking the dogs and they were getting muddy for the first time this season, I started thinking about you folks who read my blog and I was wondering what else everyone was doing to enjoy the day. I hope you got a chance to absorb some of the sunshine and the milder air, it really was a welcome change.

Sunday begins daylight saving time.  This is when sunsets make that jump and hour later to set just before 7, but the sunrise also moves up an hour meaning it won’t clear the horizon until after 7 in the morning.  If you are an early riser like me, you probably aren’t a fan of this weekend.  The good news is we are gaining light so fast; the sunrises will be back to where they were this morning in about 4 weeks.

Most of you have heard about the possible storm for next week and I will get to that shortly.  First, I wanted to write about the rest of the weekend and early next week.

 Deep cold continues across New England this morning with clear skies and enough of a breeze to make it feel even colder.  Wind chills are running at or below zero and will continue in this range the first few hours of the morning.   It’s coldest in the mountains and inland areas and less cold along the coast.   With arctic high pressure firmly entrenched there won’t be any clouds today, but highs will remain 15 degrees or more below more typical early March readings.

Temperatures begin climbing a bit on Friday when highs will break freezing from southern Maine to southern New England.  Some folks on Cape Cod will enjoy readings in the lower 40s in the afternoon.

A quick flow of even milder air arrives Saturday.  This is the day you will think you made it through winter, but don’t be lulled into a false sense of spring just yet.  Highs will reach the lower 40s in northern New England to near 50F south of Boston.  With a blend of clouds and sunshine, this will be one of the best days we’ve had in a couple of weeks. 

A cold front moves through Saturday night and pushes the above average temperatures far to the south again.   The air behind this front isn’t as cold as today, so highs will just be pushed back to slightly below average and remain there through the middle of next week.

A very cold morning for March greeted Mainers today and even the hardiest of winter enthusiasts is likely getting tired of the cold.  While not one of the top 10 coldest winters in record, the cold seems to be lingering longer this year.   According to the National Weather Service in Gray, yesterday was the coldest March day since the 8th of the month back in 2007.

Overall, winters aren’t as cold as they were in the first half of the 20th century, so for younger people this winter might be the coldest.   For those of you who experienced the winters of the 1930s 40s or 50s, the memory may have faded enough to forget how cold it was back then.

Even the winters of the mid to late 1970s and early 80s were colder on balance.  The record in Portland this morning is 21 below zero and the Jetport wasn’t even as low as zero today.   That record was set way back in 1950, at a time when Casco Bay would still freeze over. Nonetheless, perception is reality and this seems like an unusually cold winter to many of us.
