Models Advertising Late Month Storm And Cold Front

Recommended Posts

The last part of the storm is in the upper 30's for all of us, while 850's are well below freezing.

.75" of precip falls during this timeframe.

After the storm pulls away, euro indeed does show temps below 32, even in the city for Sunday night into Monday morning.

Thanks

It would be nice if we could beat out last year by a week.

Getting the upper low to close off would help like last November.

that was a pretty sweet block right there to get that to stall and retrograde. Picked up 1 inch from storm. UKMET nailed it. I remember posting the UKMET soundings and how cold they were. It was spot on.

GFS is all northern stream. Totally sheers out the southern vort whereas the Euro is a split stream phase.

GFS has a bad bias of sheering out vorts.

It may give a similar solution but in a totally different way.

Right now the UKMET would be a GFS/EURO compromise.

GFS starts to close of 500MB low over great lakes at hour 111. Looks like it will swing right under or over KNYC but appears surface low is way OTS as it totally sheers out whatever was in the south. Euro already had storm forming over the south at this time.

Yeah, it was great early pattern for snow like the end of October back in 2008. New Jersey did well with that one.

despite losing the 'southern stream' vorticity in the upper air pattern, the gfs still shows the volatility of the pattern with the degree of northern stream trough amplification that occurs. this shortwave is very strong in itself and, being helped by a rolling ridge over the rockies and weak transient blocking near greenland, can amplify pretty rapidly. i would have to think, at this point, that the system will come farther west than the gfs indicates on it's 18z run.

The model is just atrocious beyond 84 hours with southern stream vorts, especially with a fast northern stream flow. Its dampens all of them out to the point they don't even exist. The northern stream is so potent it closes off over Michigan yet can't interact with any kind of surface reflection because what little energy is left in the southern split stream is way too far out to sea. The whole trough should be sharper as the two streams interact, but alas, the gfs craps all over it.

Even sadder is how the gfs ensembles barely show anything either, and they are supposed to offer some kind of control, yet we continously see them follow the op no matter what.

Someone should pull up the experimental GFS and see what its showing.
