Gfs and cms show a big storm next weekend

Euro and gfs on board with a coastal rainstorm. Now the question will be how strong ?

Alot of snow for interior new england

And it's gone on the 12z Euro Very fickle situation All about timing

It wasn't that far off from the Euro solution. A ton of energy on the backside.

Strong signal on the gefs and eps for a noreaster.

Hurricane force winds for New England coast in the Euro If this was a little big earlier to phase. Wow big potential

What a bomb on the Euro Hurricane force winds for New England coast. If this was a little big earlier to phase. Wow big potential

The storm at 240 is well into Canada. The 850 line is off the coast.

Canada

This is with a sloppy phase. Imagine a cleaner phase? Pattern supports a big coastal storm

Euro shows alot of rain and wind for next weekend. Low goes over NYC. Sub 1000. Sloppy phase.

Euro ensembles still show a decent signal for a coastal storm at the end of this month.

43 here

12z gfs has the coastal storm again. Cmc is also close.

For now the models lost it but the pattern does support it.

Earthlight "The threat for a significant storm along the East Coast from 10/25 - 10/30 can be traced back to the larger scale pattern evolution in the North Pacific Ocean. A jet extension and poleward amplification of a ridge into British Columbia jump starts the pattern change."

55 right now in Brooklyn

18z gfs shows a strong coastal rainstorm for the area

Agree with snow possible in New England

Big storm is quite possible with the pattern depicted.

Euro crushes new england at 240

Larry Cogrove "The turn to colder air over much of the U.S. in this past week is really only the start of some major weather changes. Because as we approach Halloween, the threat for a large scale major storm and follow-up cold spell will be increasing. A prominent Kelvin wave is solidifying over the westernmost Pacific Ocean above Indonesia. As the Madden-Julian Oscillation is expanding eastward, this impulse may link with the polar westerlies (see shortwaves in the PRC and east of Japan), and start the process of amplifying the jet stream with a ridge over Alaska and western/northern Canada. That action would force digging of a 500MB shortwave into the lower Great Plains around Oct 25. Now this is the important part! At the same time that cold air drainage and central U.S. disturbance is taking shape, the tropical Atlantic Basin may supply a warm-core impulse or moisture fetch into the Gulf of Mexico. There are two viable candidates for warm-core cyclogenesis (Caribbean Sea and Lesser Antilles), and one or both of these systems could get drawn into the deepening extratropical storm as it approaches Appalachia and the Eastern Seaboard Oct 27-29."

Euro is also gearing up for the big storm at the end
