Potential major phasing event this weekend

Wow, a lot seems to be depending on this block, and heights NE of this thing preventing an exit east, as the upper low comes in from the west and captures it. This was headed for an escape before it hit the brick wall over NE Canada, and then the upper low swooped in for the kill. I would take westerly or offshore winds here anyday over easterly or onshore winds like the GGEM yesterday showed with a track into NJ, but the effects here would still be horrendous. Eastern New England would get a devastating blow.

& you have to imagine we would have major damage In the tri state area as well.

It really looks like very subtle differences are going to make the difference between capture and OTS.

In all honesty, it seems to make sense. Follows the path of least resistance. It gets wedged between the sharpening trough and atlantic ridge. With a block over the top it seems to get captured by the energy diving into the trough depicted by the euro. Then its game over.

936mb? :o

Just to compare, Hurricane Andrew's landfall pressure was 922mb. Does anyone know offhand what the 1938 hurricane's landfall pressure was? Have to think this is overdone, but anywhere close to this intensity would be beyond a nightmare scenario for many of us. We're lucky this is still 6 days out.

Just to point something out, some of the modeled wind fields have shown the strongest winds on the NW side as opposed to the right front quadrant, and a rather large wind field. Just because the winds would be more NNW over this area doesn't mean that we wouldn't get very stong winds. This isn't your typical, classical landfalling tropical cyclone.

941mb I believe.

Yea there are several other factors that add to the wind factor including, but not limited to, the tight pressure gradient and the jet associated with the trough. Regardless, with the euro setup, your going to get winds and substantial winds at a minimum.

I see a number of similarities between this setup and the 12/26/10 storm, besides it obviously being October and a tropical feature being in play. The massive block then prevented the low from exiting out to sea, slowed it down, and a well-timed phase provided for the wicked storm we have. That block makes me believe the nightmare solution is in play. If it weakens in subsequent runs, the odds of an escape or weaker coastal low feeding back to Sandy make more sense. A slightly quicker phase or slower Sandy means another slam into NJ solution. Nothing off the table at this point.

Yeah, the 500 mb composites are close at 120 hrs before the models diverge with track. Some very anticipated model runs

over the next several days to say the least.

Even if this doesn't happen, to have it depicted on model guidance for many runs is historic in itself. Underscores the insane potential here, very anomalous pattern.

Isotherm according to the euro it looks like sustained winds of 65-70kts. Wonder what the gusts would be? Not only that but this storm in itself is gonna be nothing short of memorable for all in the northeast if it happens as the euro forecasts

Upton Put a HWO out.

HAZARDOUS WEATHER OUTLOOK

NATIONAL WEATHER SERVICE NEW YORK NY

355 PM EDT TUE OCT 23 2012

.DAY ONE...THIS AFTERNOON AND TONIGHT.

HAZARDOUS WEATHER NOT EXPECTED AT THIS TIME.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY.

THERE IS LOW POTENTIAL FOR A MAJOR COASTAL STORM WITH HEAVY

RAINFALL...HIGH WINDS...COASTAL FLOODING AND BEACH EROSION EARLY

NEXT WEEK. THIS WILL ULTIMATELY DEPEND ON THE EVENTUAL TRACK AND

EVOLUTION OF TROPICAL CYCLONE SANDY AS IT INTERACTS WITH A

DEEPENING UPPER LEVEL LOW PRESSURE SYSTEM APPROACHING THE EAST

COAST. THE STORM MAY VERY WELL JUST MOVE OUT TO SEA...AND HAVE

LITTLE IF ANY IMPACT ON OUR WEATHER.

AGAIN...FORECAST CONFIDENCE IS LOW AT THIS POINT...SINCE SANDY IS

STILL IN THE CARIBBEAN SEA...AND ANY POTENTIAL IMPACTS ARE STILL

AROUND A WEEK AWAY. PLEASE REFER TO THE NATIONAL HURRICANE CENTER

FOR THE LATEST FORECASTS ON SANDY...AND MONITOR THE LATEST

NATIONAL WEATHER SERVICE FORECASTS THROUGHOUT THE WEEK.
