Guest Pamela

everything good has collapsed this year for me

I rememeber being depressed for a spell when I was your age (a long, long, time ago). Don't worry, you'll get over it. These are the best years of your life...my father told me the same thing when I was your age...didn't believe him...but now realize he was 100% correct.

Where do you think storms are worse, Plainview where you used to live, or Port Jeff? Im thinking Plaintview further west, but PJ is north so you get those nasty cells from CT...

Moved to Plainview in 1971...resided there until 1994...there were certainly some good t-storms there over the years...but as far as comparison and such...a good deal harder as there were so few weather resources outside of NOAA weather radio and TWC radar did not come along till 1982...and internet not till a decade later...as I posted a few days ago...Port Jeff seems exceptionally wet during the summer (at least during my watch)...and they seem a fair bit wetter during the warm season than say the East End where sea breezes obviously promote stability and discourage the development of cumulonimbus clouds...but as far as comparisons...I have not owned a rain gauge in recent years so I could not say for certain vs Plainview...I'm more of a winter climate guy (in terms of interest)...and can say w/o equivocation Port Jeff is a good deal snowier than Plainview...even though the period I lived in Plainview was in general a bad stretch for snow relative to normal....while the exact opposite has been true while living out here...

Smok eater just couse you dont agree with what I said doesnt mean that it's wrong so just keep your pics to your self and do what your name says and eat smoke

Is it possible that you can actually add something to the discussion, other then stupid blabbing and whining? I highly doubt it.

Thanks for proving my point, lol. I won't muck up the thread any longer with arguing, I suggest you do the same with your whining.

So when are the storms suppose to be firing today? After 2-3 or earlier than that? Rain, wind and hail being the biggest threat today i think anybody who can get under these storms today should see a pretty good thunderstorm. Cape values are more than adequete, how about the shear/mid-level lapse rates?

You can see the clouds with the front to our north across NY State. It looks like severe convection will

fire later this morning to our north and drop down toward our area around 17-18z. We are already destabilizing

quite nicely for so early in the morning.

And this is a lesson to how the grass is always greener. My mom was raised in Plainview, lived there from 1955-65, and to this day will complain about how Plainview was SO much snowier than anywhere else she's lived in the NYC area. No amount of data will convince her otherwise.

Expect Severe Thunderstorm Watch to be issued for all of NYC Metro any time now - probably be the first of at least 2 issued today the second being for areas south and possibly further east of the metro in long island and across central and southern NJ and southeast PA ..............main threat is strong straight line winds - hail and frequent lightning .........also locally heavy rain causing flooding in poor drainage areas

Looks like the worst will be moving through right in the middle of rush hour...should be a disaster of a commute home.

It's a shame that nobody reads Upton's AFD's

Pretty good one regarding todays threat.

BASED ON MESOSCALE MODELS OF HRRR AND NSSL WRF...STRENGTHENING

CONVECTIVE CELLS START FIRING UP ALONG ACROSS THE ALLEGHENY PLATEAU

AND THE HUDSON VALLEY AROUND 17Z AFTER WHICH THEY WILL BE ON A

SOUTHEAST TRACK GOING INTO THE LOCAL FORECAST REGION. FURTHER

DEVELOPMENT OF CONVECTION COULD ALSO OCCUR FROM CONVERGENCE ALONG

THE SEA BREEZE BOUNDARY ESPECIALLY WITH ANY OUTFLOW BOUNDARIES FROM

CONVECTION MOVING IN FROM THE NORTH AND WEST. WIND SHEAR OF 25 TO 30

KT FROM 0-6 KM WILL ALLOW FOR SOME THUNDERSTORMS TO PRODUCE HAIL AND

GUSTY WINDS. PWATS NEAR 2 INCHES SO HEAVY RAIN ALSO CAN BE EXPECTED

WITH THUNDERSTORMS THAT FORM. THIS IS CONSIDERED ESPECIALLY SINCE

THE FLOW WILL BE NEARLY PARALLEL FROM LOW TO MID LEVELS WHICH WOULD

ALLOW FOR TRAINING OF CELLS. THE CONVECTIVE MODE LOOKS TO BE SQUALL

LINE TO BOW ECHOES.

if we hold onto sun today, all areas will torch.

we are off to the races here with the temp - just touched 90 at 9:25 am in northern middlesex county NJ - if we continue getting enough sunshine we will hit 100 before noon - impressive to say the least .....

Poor choice of words on my part. Just seems like there are some questions on here that could be easily explained by reading their discussion.

Things should continue to destabilize as that front drops in. Already close to 55 knots of bulk shear in NY state.

...STRONG TO SEVERE THUNDERSTORMS EXPECTED THIS AFTERNOON...

A STRONG COLD FRONT WILL PUSH SOUTH ACROSS THE AREA THIS AFTERNOON.

THE HEAT AND HUMIDITY OF THE PAST SEVERAL DAYS HAS CREATED A VERY

UNSTABLE ATMOSPHERE ACROSS THE REGION...AND THIS WILL LEAD TO THE

DEVELOPMENT OF WIDESPREAD THUNDERSTORMS BY EARLY THIS AFTERNOON.

THE FIRST AREAS TO SEE THUNDERSTORM DEVELOPMENT WILL BE ACROSS FAR

NORTHERN NEW JERSEY AND THE LOWER HUDSON VALLEY...BEGINNING AROUND

NOON OR 1 PM. THESE STORMS WILL THEN MOVE FAIRLY QUICKLY TO THE

SOUTHEAST...REACHING NEW YORK CITY AND COASTAL LOCATIONS BETWEEN 2

PM AND 4 PM BEFORE MOVING OFFSHORE BY EARLY THIS EVENING.

SOME OF THESE STORMS WILL BE SEVERE...WITH DAMAGING WINDS IN EXCESS

OF 60 MPH AND LARGE HAIL. FLASH FLOODING IS ALSO POSSIBLE AS THE

MOIST ATMOSPHERE WILL ALLOW THESE STORMS TO PRODUCE 1 TO 2 INCHES OF

RAINFALL IN A SHORT AMOUNT OF TIME. FREQUENT CLOUD TO GROUND

LIGHTNING IS ALSO EXPECTED.

STAY TUNED TO NOAA WEATHER RADIO AND LOCAL MEDIA OUTLETS FOR THE

LATEST INFORMATION.
