Friday February 6 FROPA / WINDEX small event

[The 4 Seasons]

@ORH_wxman @CoastalWx So did Logan get 5.2 or 5.4? Their PNS and ob on the interactive map says 5.2 but they recorded 0.2 on the 6th before midnight and Feb 7th says 5.2. 

One of them is an error 

I'm gonna go with 5.4 since thats what's in the record books

 

[ORH_wxman]

Yeah unless they change the F6 data then I’d go 5.4. 
 

Id prob hedge higher anyway since they had 4.2” at 1pm and got smoked for a while. I thought they’d finish with 6”+. 

[CoastalWx]

Yeah 5.4 makes sense.

QPF is also off...nearly 40:1 ratios. i figure bad catch again from the winds yesterday, shame they don't fix that.

ORH is more reasonable 5.2/0.31 17:1

[The 4 Seasons]

For Logan? I’ve mentioned this before, but their gauge is always off. Dendrite mentioned that it shouldn’t be based on the type, but they are always low. Always.

ORH used to have that problem. Not as much these days but check out some of their old reports from the 2000s and 2010s. Some of the storms are like 50 to 1 ratios.

Even in all rain events they’re low. Especially if wind is involved. At first I thought it was coincidence, but in the events where I’ve compared around, they are low when wind is involved. 
 

I’m sure when snow is involved it’s worse.

Preliminary snowfall totals for CT. I'll have all the final maps for CT/SNE/Tri-State done by tomorrow morning ish. May end up needing to change the ranges well see. Highest CT report is 4SW Voluntown @ 10.8"

The heated tipping buckets early in the ASOS era were terrible. I think they’re all over to weighing gauges with antifreeze now.

whats your thoughts on the 16.2 in beverly? legit? im debating whether or not to include it in. There is also a 13.6" report in SW beverly which seems to be a bit more realistic and whats in line with surrounding totals. But i still can see 16.2 being possible right in the sweet spot

There’s a guy that plays a musical instrument that went there yesterday to take measurements. This dude said no more than 8-10 anywhere there .

Much like summer thunderstorm rainfall totals, these meso-scale banding events can have extreme differences across very small distances; think lake effect snows???  I would dismiss it off hand?

But they show a 12 to 16" color zone?

They were pounding when all of those 10-12” reports came out yesterday mid morning. I honestly expected to see more 15-18” obs. Those who cleared probably did, those who let it set probably stuck around that 12-13” mark.

[dendrite]

The w.e. checks out

[dendrite]

And for shids and gigs the BOS radar estimates. Obviously the values don’t explicitly matter, but it at least gives you an idea of who had the most. Looks like that little finger of green is right where that total was.

[ORH_wxman]

Yep I’m with @dendrite, I was surprised we didn’t get more 16-20” reports when we had a bunch of 10-13” reports by mid morning. So I’d say that 16” is legit and there’s prob a few more areas that did just good near them but didn’t report.

Oh no i totally agree with you and dendrite. If you seen some of my posts from yesterday I said I expect to see 15-18" totals since some of those were from mid morning 9am to noon. Just the fact there was only one gave me some pause and the other Beverly report that was less by 3". But i do believe it, just expected more of them. I can only fit one,  so i have to choose what to include.

Of course he did. 

There's also plenty of 3-4" reports in Cumberland

Fixed ranges. So the 13" reports will pop a 12-18" color range even without including the 16.2.
