January 2nd/3rd Storm Observations

Recommended Posts

Blizzard warnings have a low rate of verification. Being conservative with them is probably the way to go.

Every coastal community from Rockland ME to Provincetown to Long Island NY has blizzard warnings. Boston does not. What is different about the 5 mile stretch of suffolk county coastline? Absurd

 

Hey @NWSBoston, "close call for Boston but expect near blizzard conditions tonight." What's different in Boston vs Revere, just up the road?

I'm about to drive from KSNOW at CN Mountain to West Roxbury, MA.

Jumping Ship for the First Time Ever for a big storm!

I WILL TRY TO GET TO JIM CANTORE AND PLAY ON TV SO:

- If you know where he is, Tell Me!

- If you know Jim, Tell him I'm Coming!

- If you are in Boston and want to hang like Weatherfella and such, Tell me!

Thanks to all the responses on TDWR vs. traditional NEXRAD for OES.

 

Re: wavelength / resolution, I've read TDWR uses 5cm vs. 10cm on standard WSR-88D radars. The shorter wavelength gives it higher resolution, but it also results in attenuation by things like heavy rain drops which can more easily scatter the shorter wavelength beam. But the wavelength / resolution is not what allows better depiction of OES.

 

So as for the OES, the elevation explanation makes sense. Why the difference in elevation? TDWRs were designed to alert airports of low-level issues that could impact takeoff/landing, so the radar beam is pointed very close to the ground, so lowest tilts are 0.1-0.3˚ vs. the lowest elevation angle of WSR-88D radars which is 0.5˚.

 

We don't get to appreciate this much in SNE. Cool learning point!

appreciate box mentioning the potential screw zone I just hope it is east of here..actually  I  hope no one gets screwed with it and theres just a big snowstorm area wide tonight!

something unique will need to  happen for that 12-16 stripe or necn's 12 to verify in this area though

 

lol.  I agree with you, a foot seems unlikely out here.  Nexrad suggests a hellacious band is overhead, but really the vis wasn't too bad at all.  Accumulating reasonably well but tiny flakes presumably due to weak lift.

Amazing short duration temperature change at ALB today ... just incredible

Every coastal community from Rockland ME to Provincetown to Long Island NY has blizzard warnings. Boston does not. What is different about the 5 mile stretch of suffolk county coastline? Absurd

Well the line has to get drawn somewhere, and it looks like the other zones (except Long Island) are east of Boston, so perhaps that has something to do with it.

The thinking behind verifying these warnings is the higher winds at the coast. Point being, there should be no difference between here and most of those other places. More people here though, which increases danger I would think. But I digress

And for cryin out loud, give me a blizzard warning... the Box snowfall map just highlights how skipping Boston metro is puzzling

 

Well it has nothing to do with snowfall amounts, just visibility, wind speed, and duration.

 

It's silly because in all likelihood it was done to avoid putting their largest city in the blizzard warning. But they are up surrounding BOS so this storm will be called a blizzard whether they wanted it or not. Heck it was called one before today.
