Feb 27 Storm

Well, it seems we can't for more than a few days without the threat of significant snow here in New England.  We're back at it again tomorrow as another strong low pressure system will push through the region.

The good news for some is that it will be warm enough for all rain or mostly all rain.  The bad news is that where it will be cold, there is going to be quite a bit of snow.  I've outlined my thinking in the graphic below.

Again, credit goes to Plymouth State for the underlying map.  Please excuse my poor drawing skills.

Anyway, the headline of this storm should be "Elevation Snow".  Places that are generally above 1500 ft or so are going to have quite a bit of snow from this one.  Ski resorts throughout New England, Rejoice!

This will be quick hitting storm, arriving during the pre-dawn hours of Wednesday morning and continuing into the early evening before departing Wednesday night.  It will impact 2 commutes however.  Most places outside of I-495 in MA will start with snow Wednesday morning.  As the morning progresses, temperatures at the surface will begin to warm and the snow will begin to mix with and then change over to rain.  The further north and west you are away from Boston, and the higher you are in elevation, the snow will begin to pile up quickly after 10 AM.  I expect that Central and Northern NH and Western Maine will see the most snowfall, similar to the storm over the weekend.  I wouldn't be surprised to see a few spots have a bit more than 12", but those locations should be isolated and mainly on higher terrain.

This is going to be a wet heavy snow again.  Take care when you do your digging out!

Storm progress

So that lack of confidence in my forecast is paying off.  Warmer temperatures are hanging in a lot longer than I expected along the coast of Massachusetts.  This is going to result in much lower snow totals inside of I-95/MA-128.  Eventually colder air will take hold and the majority of the rain will transition to snow, but the snow will not live up to my forecast totals.  It looks like along the I-495 corridor into Central and Southern New Hampshire will see the highest snow totals.

Even those numbers will not be impressive.  I don't expect to see many reports of over 6" when this storm is over.  Here in Hudson, we have about 2" of heavy, wet snow.

The location that is going to have the most snow from this system is going to be in Maine.  It's been cold enough there from the beginning.  The snow will continue there for a good portion of the day.  I expect to see a few spots that top off around 10".  I didn't focus on this area too much because I don't have too many readers from this area.

Overnight last night and early this morning, areas around Concord had a prolonged period of moderate to heavy snow.  This put anywhere from 1-6" of snow down, most places received about 3-4".

Expect the rain/snow to continue through at least the early afternoon before gradually tapering off in Eastern MA and Southern NH. Central NH and Maine may continue to receive snow into the first half of the night before the storm begins to weaken and pull away.

I'll share some links tomorrow that show the final snow totals so I can show you how badly I forecasted this event!  :-)  I'm not afraid to admit I blew it.

Thanks for reading!
