SREF's are decent. Plume mean at IAD is close to 3".

Interesting map! I was going to ask about the source, but I see the College of Dupage Weather url at the bottom.

It's kinda funny how none of us are really taking this seriously or talking it up.   If this was 2 weeks ago, this place would be hopping.  

 

I guess it depends on what one considers exciting. Outside of the far burbs, there won't be any more societal impact than a rain storm. Top end closer to the cities is probably 2" if it falls hard enough to stay ahead of the melt. If I get an honest inch I'll be pretty happy. I'll have to make sure I time the measurement because it's gonna get zapped pretty quick. 5:1 ratios might be close to best case.

I think it's due to ground temperatures. Two weeks ago we still had a snow pack. Now we have nice 60F days and even stronger March sun.

Good snow generally doesn't happen this late esp near the cities. It could in the period ahead I guess but this event looks way marginal except maybe a lucky elevated zone. Plus people keep mentioning algorithm snow which is way off on this one from what I've seen.

We just don't know yet.

we may still be saying that about the NAM for Friday on Saturday

personally, I've been keeping an eye on Friday but at this time of year I won't feel very confident until Thursday's runs are showing accumulating snow

Exactly. This is far from a 10:1 event. 5:1 might be generous if it comes in sporadic bursts. We need a solid 4 hour period that drops .3-.4 or there won't be much to measure.

Sun angle?

 

Maybe once the temps crater tonight people will think about snow.  Right now, people are thinking about outdoor activities.

rain to heavy wet snow to rain for Friday morning :lol:

Accums are loltastic as always on the NAM

1-2" doesn't seem all that crazy or loltastic to me if this works out.

ETA: tropical tidbits shows 1-2, while instantwx shows 3-5.

I think it's obvious which one is more trustworthy, but any fault in the clown map is on the algorithm, not the model itself.

btw, 15z SREF plumes were interesting :lol:

ETA: And so are the 21z ones too

What do you think the odds are that you will be copy/pasting a government issued winter weather product for our region within the next 48 hours?
