Wonder if all the model flip-flopping is satellite related?

 

SENIOR DUTY METEOROLOGIST NWS ADMINISTRATIVE MESSAGE NWS NCEP CENTRAL OPERATIONS COLLEGE PARK MD 2331Z WED OCT 22 2014   NCEP IS NOW RECEIVING THE FOLLOWING NESDIS SATELLITE DATA FOR 00Z MODEL INGEST..   NPP - CRiS AND ATMS DATA GOES SATELLITE DERIVED WINDS GOES RADIANCES GOES SOUNDING PRODUCTS   THE FOLLOWING DATA TYPES CONTINUE TO BE UNAVAILABLE FOR THE MODELS..   MODIS IR AND WV WINDS OMI OZONE DATA AIRS HYPERSPECTRAL SOUNDER DATA COSMIC GPS-RADIO OCCULTATION DATA   NESDIS CONTINUES TO WORK ON RESTORING ALL THEIR SATELLITE DATA PRODUCTS..   IT IS DIFFICULT TO ESTIMATE THE EXACT IMPACT OF THE SATELLITE DATA OUTAGE ON NUMERICAL GUIDANCE AT THIS TIME.. BUT THE DEGRADATION OF THE MODELS INCREASES WITH AN EXTENDED OUTAGE..   SHRUELL/SDM/NCO/NCEP

I don't see the flip-flopping day 7 on to be unusual.

It could just be a coincidence, but the 7-10 day has been seeing some pretty big swings this week.

The Euro ens 500 mb chart usually doesn't fluctuate this much with trough and ridge positions.

Frankly, the OP Euro looks ridiculous.

Both the GFS and Euro are showing a trough along the east coast next weekend - the details of where any storm system will develop are stll in question - what is interesting is snow cover is forecasted to increase dramatically in Canada next week as colder air shifts south towards the U.S. and if a storm does develop it will have some cold air to work with..........

My bet is on if this storm is the right position that still only the people in the highest elevations may see some accumulating snow. Regardless the dramatic increase in canadian snow cover is promising and may add us further as we head into december for all concerned in our area

DT just posted something on this storm on his fb page

and look what he posted just 2 days ago - I am still not buying into the extreme solution for this potential storm because of the models posssible reaction to the missed satallite data.......plus the AO and NAO aren't exactly that favorable for an extreme solution - in fact that dramatic buildup of Canadian snowcover might be wrong too

Over the past several years, we've found that the best way to look at situations and storms like this is "always highly unlikely, always very possible". In just 5 years, we've had several blizzards and huge "100-year" snowstorms, "100-year" flooding, an October snowstorm and a hurricane. Nothing is out of the realm of possibility

Agree 100 % - Also I think we should wait till we are within 5 days of the possible event before we start showing intense interest in this storm especially since there is missing satallite data which could have an effect on the longer range model solutions - but I am sure someone here will try and make a new storm thread very soon

 

In addition lets see if that increase in Canadian snow cover forecast verifies next week
