3/17-3/18 Storm Threat Discussion


Zelocita Weather

Recommended Posts

Care to explain a bit?

 

992 mb low 75 miles off Atlantic City at 234 hrs.  QPF over 1 inch.  A bit warm verbatim, but it has ensemble support from last night and the ensemble mean was also colder

 

It will probably end up being suppressed though and being a threat for Virginia again though, lol.

What do you think the chances of south shore of LI getting in on the winter weather advisory? Upton is hedging their bets with this northward shift and are still going with conservative amounts. The 18z model runs will be interesting nonetheless.

Highly doubtful. Most of Middlesex county gets less than 2 I think so advisory levels probably not reached (at least the northern part)

SREF trended a bit south and lower with the totals.  I think the north trend is done.  It now looks nearly identical to the Euro.  Go with the Euro now.

 

SREFs were definitely too far north at 9z, the mean now looks reasonable and resembles much of the other guidance except for the NAM which is now south of pretty much everything.

Just to give you an idea on the EC the past several runs.

 

Philadelphia two runs ago .8

Last run 1.8

This run 3.8

 

Belmar two runs ago .5

Last run 1.4

This run 3.0

 

New York City two runs ago .00

Last run .01

This run .08

 

Areas of Western Virginia went from 4 inches to 9 inches

 

Are you mixing liquid equivalents and snowfall here or is NYC really still getting that little snow (or are Philly and Belmar in for feet of snow, lol)?

Probably a snowballs chance in March of that happening. Would be surprised if the island saw any precipitation at all. Uptown I think is erring on the side of caution.
