1/11 Cutter w/strong winds - snowbank demiser

Recommended Posts

Looks like a 45-55 degree temp thaw on Saturday, with a 3-4 hour window of 25-30 mph sustained SSE winds with gusts to 45-50 mph.  850 and 925 mb winds above 65-70 knots. Heavy rain and strong winds possible as modeled now. Winds look stronger than last cutter which had 35-40 mph gusts.  Potholes and roads like the moon will be common this spring. Cyclical freeze annd thaws, means many more potholes.  Discuss.  Behind cutter nice looking Sunday w/ 45-50 degree highs.  Looks like a S. Screamer to a potent Miller B snow/blizzard chance around MLK weekend. Split and displaced PV revisited again too.  Gas, stabilizer and earplugs on stand-by for snowblow opptys.

So should we expect our leaf out in May or June this year?

The QPF for this event looks to be at least 1" to 1.5"+

 

So far the 12z GGEM is leading the pack with 1.5"+ for NNJ and 2.0"+ for the city and Long Island.

 

It will be interesting to see if the rainfall reaches excessive levels and what impacts if any that it will have on the frozen rivers.

 

The 12z GEFS ensemble mean was 1.5"+ for all areas which is pretty impressive for a low resolution ensemble mean.

RESULTING IN SIGNIFICANT RUNOFF.

STRONG TO HIGH WINDS...MAINLY EAST OF NEW YORK CITY ACROSS LONG
ISLAND AND SOUTHERN CONNECTICUT SATURDAY AFTERNOON AND NIGHT WHERE
SOUTHEAST WINDS OF 20 TO 30 MPH COULD GUST TO AT LEAST 50 MPH.

This is beginning to look like a high impact event for the area. Most of the guidance is in good agreement on multiple convective waves crossing the area beginning with late Friday night and lasting through most of the day on Saturday. If the 12z 4k NAM is correct a fire hose type feature will cross the area between 15z and 21z Saturday. The 4k NAM drops a quick 3-4"+ of rain in a narrow band centered right over I-95. The NAM also has surface winds of 75MPH plus just south of JFK valid 21z Saturday. PWAT's look to get above 1.5" which is extremely anomalous for January. The combination of potentially excessive rainfall, melting snow/ice and a frozen ground could promote high run off and flash flooding potential along with a river flooding threat for NJ.

Like most heavy rainfall events for the tristate its going to be NYC into jersey and up to the hudson valley/ catskills that get the brunt of the moisture. I can almost guarantee that LI will be light-moderate rainfall in comparison to west of us while we get the headlines for the wind part of the storm. Cannot tell you how many times LI was shown as a bulls eye and inland ends up getting the most. Not a wishcast more of a typical scenario for these types of events

The 12z ECMWF is over 2" of rain for far NNJ and over 2.5" of rain for parts of NJ.

 

HPC following through now with day 2 risk of excessive rainfall

Edited at 4:55PM 1/9/14 for 18z RGEM

 

The 18z RGEM continues the trend of being super amplified and brings a tremendous surge of moisture into the entire eastern seaboard.
