KDOX issue:

Dec 24 2020 22:42:02

Dover AFB Radar (KDOX) is currently experiencing some data quality errors due to an ongoing equipment issue.  While velocity (V) data appears representative, reflectivity data (Z) is running high/"hot". Technicians have been notified and will continue to troubleshoot the radar over the coming days. Please use this data with caution for the time being. Thank you and we apologize for the inconvenience

Just finished dinner waiting on dessert and the winds! The sustained winds are so far more impressive then gust atm

Most models show some gust 50+ starting 10 or so let’s see there’s a lot of 35-40s starting to pop up 

[nycsnow]

00z hrr more impressive has more widespread 70+ gust

Starting to gust 35 or so out here, steady roar now.

Yeah last 30 min or so you can def hear the winds above surface 

[nycsnow]

00z nam looks like it might be over 100 at 850

Virtually no wind here at my parents' house in Allentown. I'm hoping to see some good gusts before bed.

[nycsnow]

Actually had my strongest gust so far today under this rain. Upton was mentioning rain will mix winds down 

[Big Jims Videos]

Windows just began to rattle here in Point Pleasant Beach 4 blocks in. Merry Christmas everyone.  Hope you all have a safe night and let's hope it's not as bad as it can be.

Getting some bigger gusts now in Lindenhurst, highest so far is 41 mph but that is probably going to get broken soon. Temperature has risen a couple degrees to ~57.5. My snowpack is officially dead too, not one spot left in my backyard

Hanging on to the last patches of snow in north Lynbrook. Very apparent now that significantly more frozen precip occurred here then at my Dads in south wantagh.

Winds are still pedestrian. Going to do a drive to the beach during peak winds 

I wonder how much the difference was?  we got 8" here

The most rain would be in upslope areas in NY/NJ that typically do well in SSE flow events like this. Otherwise I wouldn’t expect more than 2” in any particular place. Main story from this would be winds-which are kicking up here in Long Beach. Having an eggnog and paying a vigil to the few remaining snow piles. 

the key is drinking just enough not to care about disappearing snow piles lol

or maybe a little more than that

It’s not often you can stand in 40-50 sustained gusts in the 60s (70?) right on the beach front. I have done it a few times, the last being March 2010. I was at work on the uws during Isaias and sandy was too dangerous to get near a beach. 

we need to compile a list of all the 70+ mph wind gust events in our area, I bet the list isn't that long.

Intense radar returns down in DE/MD and radar getting quite robust to our south. Heading north.

whats that area of yellow and red thats been stationary over SE PA and DE for hours now?  How much rain have they gotten there?  Why hasn't it moved?

I was at the beach during Isaias.  The sand blasting I received was brutal and it was tough to stand.  

Could you imagine being at the beach for the Boxing Day Blizzard?  You'd be getting both sand blasted AND snow blasted!

I think that was the highest winds we've experienced in a pure snowstorm?

Per weatherwiz in NE forum it’s more likely something funky is happening with that radar. Observations/ground truths I’ve seen don’t match appearances 

I was thinking that too- it's been stationary for hours over the same area for no apparent reason at all.

Agreed, you can see it on RadarScope that the one radar, KDOX, is funky down there making it look much worse. 

Yeah and there's no reason it would be like that over one area for hours on end.

Yeah definitely no way we have 75 DBz+ echoes happening at the moment. That’d have to be indicative of some seriously incredible rain rates  which again, don’t match ground truths.

I have seen this occur before when looking over some radar imagery in the Desert Southwest—indicative of a bad radar algorithm. Here was an example from this past summer. At this point in time the areas shown here were high and dry without any precipitation occurring.

Isn't there some way for them to fix this?

Like using other radars to compensate and shutting the bad one down?

Yeah that was for like 10 min around 6:30 PM  Outside of that, no rain here

Thanks!  I heard it's been raining there most of the day!  how are your winds?

[nycsnow]

Wall of water coming up jersey shore should see some nice gust starting in that 

[TJW014]

Now occasionally gusting over 35 here. 50+ at the beach

[jhotdog]

Bell.. winds r basically non existent....just heavy rain

[nycsnow]

The NAM is overdoing it. As walt said use the HRRR at this point.
