The precipitation map from the GFS for next Saturday evening looks hauntingly familiar to the one from last week, which did not pan out in a snow event, except for the favored lake-effect areas.
But the key to this one would be colder temperatures, frozen ground in many areas, and most importantly a long duration -- the model shows snow over most of Pennsylvania for more than 60 hours. The only other model which runs in that time frame is the DGEX, which runs from GFS conditions at 84 hours. It is much higher resolution and shows the event as only happening in the higher elevations of the Appalachians Saturday:
It's hard to tell if this is just the difference in resolution talking but it seems that, unlike the GFS, the DGEX never really shows snow outside of the higher mountains.
AccuWeather.com Professional's Joe Bastardi (PRO) is also hyped, predicting a 28.80" Hg low pressure Saturday in the Gulf of Maine (the equivalent of a Category 2 Hurricane according to Saffir Simpson [Wikipedia]). He also says:
"Heavy to excessive rainfalls from Texas to the mid-Atlantic, with heavy precip that could very well turn to snow from the Upper Midwest through the Great Lakes and interior Northeast, strong winds that can gust over 60 mph in the cold part of the storm driving flurries and squalls as far south as we will see them go now, perhaps even further."
History was made by Hurricane Iselle this week and I have some of the most impressive images and maps from the storm.
We're monitoring a total of six storms in the Atlantic and Pacific, and some of them are record-breakers.
As is often true this time of year, the tropics are busy, with five notable named storms. Among them are three storms near Hawaii, and Bertha is back for the seventh time.
There's been a lot of news on amateur drones since I tested the DJI Phantom Quadcopter for storm chasing purposes last fall. Not to drone on, but let's take it from the top.
Today I'm pleased to announce a new suite of world radar maps and advisories from the national weather services of several countries on AccuWeather.com.
There's much ado this week about the polar vortex visiting the U.S. this week, but it wasn't long ago that we set over 7,800 cold records in July.
