I still dont know why im under an advisory between the snow and ice we pretty much already reached warning criteria and they way its starting to look there may be more on the way

think it has to be a certain percentage of the county getting warning criteria. maybe that's not the case? Just guessing not really sure what county you live in.

how do Euro soundings look for Boston?

I can't get soundings but the 850 temps stay cold enough...sfc is flirting in that 34F range a lot until later tom afternoon when it drops. If we get the goods toward dawn, it should be snow there, otherwise you're probably waiting until tomorrow afternoon.

32.2\31

Garbage lol

Will, are you worried....

About the totals for this storm? Not too much at the moment. It was never going to be pretty with all these separate rounds...I think round 2 is getting its act together decently.

These molasses events are bad news for low elevations in marginal airmasses.

I'll bad I never measure more than 5" OF SNOW.

Ok alls fair. :raining: .....never would have thought you wouldn't manage 5" in three weeks of February, but it was close.

I looked for a link to donate now, but not sure where it is. Someone show me how - have my credit card here.

2.5".

Make the $20 donation, Rick.

Folks need to stop betting me...it's unhealthy for the wallet.

I think you'll end up doing pretty well overall...Boston I'd be a little more worried about. I think a lot of us will rip when this 2nd round comes in based on radar...we'll see though.

You still have tomorrow afternoon to fall back on anyway where your area will be the most favored in SNE.

1:30am Box AFD update, holding with decent totals Boston-north:

Near term /until 6 am this morning/...

130 am update...temperatures continue to hold steady or slowly

rise across southeast Massachusetts as easterly flow intensifies. Already

seeing a period of wintry mix along and south of I-90 in Massachusetts...with

areas farther south transitioning to just plain rain.

Regional radars showing a dynamic system getting ready to move

over our region later this morning. This should not only bring a

period of moderate to heavy precipitation this morning...but it

should also cause the atmosphere to cool once again before the

precipitation ends...meaning at least a little more snow before

all is said and done.

&&

Short term /6 am this morning through 6 PM Friday/...

expect periods of snow or mixed precipitation to continue for much of

Thursday as coastal low slowly meanders S of ack for much of the

day. Persistent Ely low level jet will focus the steadiest

snowfall across north zones and particularly across NE Massachusetts and the

Merrimack valley where a period of heavy snow is possible. As a

result we expanded the Winter Storm Warning eastward to include

bos northward along coastal Essex County.

South of the Mass Pike...the precipitation is expected to be lighter but

the column will also be cooling during the day as the winds back.

So we expect any rain or mixed precipitation to eventually change back

to snow before ending. Additional minor accumulate is possible away

from the S coast. In addition...gusty east/NE winds will continue

over the cape/islands and east coastal Massachusetts.

This is a difficult snowfall forecast due to the uncertainty in

the northward extent of middle level warming and how much enhancement

occurs with low level jet. Our current forecast is for 8-12"

north of the Pike and 4-8" from bos northward along coastal Essex

County. 2-6" north of hfd-pvd-tan to the Mass Pike and a coating to

2" along the S coast.

Here's a cool look at the dual pol at work....you can see how defined the sleet line is south of ORH and also look how it bends to the southeast into RI which we know should happen because the colder air was a bit deeper to the east
