A little OT, but the amount of warnings on thunderstorms from Mt Holly is becoming peculiar. Most of these storms don't look severe. I might be wrong, but it seems to me that the importance of the warning itself is taken away when so many non-severe storms are warned.

THIS STORM HAS A HISTORY OF PRODUCING WIND DAMAGE ACROSS THE

FLEMINGTON AREA. THIS IS AN EXTREMELY DANGEROUS SITUATION. SEEK

SHELTER NOW INSIDE A STURDY STRUCTURE AND STAY AWAY FROM WINDOWS!

Seems severe enough to me. Would you prefer they issue a warning 15 minutes AFTER the worst severe weather has passed, like OKX did last time, (and ONLY issued because EWR gusted to 60 MPH)?

LWX warns every shower that has an orange pixel for 1 scan.

I'm not referencing any specific storm that's going on right now.

The point is if you're working in the NWS, with the mission "to save lives and property", in a borderline situation, you should just go and issue the warning. I'd rather have the storm weaken and be warned, than have it pulse up and damage property with no warning.

And then people wonder why the general public doesn't take the warnings seriously sometimes. Because the majority of the time, if you follow the gameplan you advertised, warnings are issued for garden variety storms.

Yeah, that's what im talking about. I've seen 40 dbz sea breeze thunderstorms get warned over three counties. I'm not calling anybody out, it ju

st is peculiar to me. I'm sure they have their reasons.

John, my father lives in Flemington and that storm was NOT severe (technically speaking) the lightning was bad and very heavy rain but no damage in the immediate vicinity of him. These severe warnings do get overhyped on a daily basis.

Another thing to take into account is if you issue a warning for an area, and a very small portion of that area verifies, the warning is verified and was needed. Most of the time, even in verified warnings, everyone doesn't see severe weather. The general public is always going to have this perception. What would your game plan be? Wait until the storm is over, or somebody already calls in damage? It's easy to verify 100% then, but when NWS wants increased lead time, you're not doing your job,

Someone reported wind damage. Last week, the storm that produced 60 MPH winds at EWR (only 2 miles from here), and apprently knocked over a light pole on 1 & 9, only produced 35-40 MPH winds here- nice storm, but nothing that special. Sometimes, severe elements of storms can be very localized, especially in a small cell. NWS can't issue a warning for a 1X1 area. They have to issue a warning when damage is reported.

I get the impression they are loose with warnings of all types to pad their lead time rates. There is no incentive not to warn on marginal or sub-severe activity that *might* become severe. The false alarm rate is a big problem that needs to be further addressed. There are lots of people who don't take severe warnings to mean anything because it's so common to get one with nothing major happening.

The only times I really see them overwarn is when a storm is pulsing up, or when there was damage reported somewhere, like the "derecho" line. Most of the warnings out of the referenced NWS office have been verified.

Your right, it must of been a very localized area nearby.

I meant "they" as NWS as a whole.

Sussex Co warned again currently...must be the 10th warning we have had this year so agreed with the over warning. No major damages from most of them.

Sussex is a large county. If you issue a warning for Sussex County, and there's a wind damage report somewher in the county, it verifies. And it doesn't really have to be "major" damage.

The bigger problem for LWX is the amount of TOR's the last few years.

31 in 2010, 96 in 2011, 28 in 2012 for a total of 155 in 2 and a half years.

Only one tornado during that span reached greater than EF-1 strength.

The public in the highly-populated Balt-Wash corridor might be getting

confused as to what a Tornado Warning actually means anymore.

Mt. Holly has had a great year with verifying SVR's, but today does look to be a little

bit much. Pulse storms are always difficult, and with a younger warning forecaster

on call for the northern half of the CWA today, sometimes days like this happen.

The intial SVR's were issued by the younger forecaster, which is why a few may have been

a little bit much, however the southern half of the CWA was covered by the veteran, who also

assisted with the SVS/SPS's in the other half. "Rainshadow" might be the best warning

forecaster at any of the 122 offices. Always one to have for a major severe event.
