Gangnam Style was a big deal musically and choreographically during the fall and early winter. For a much briefer period, springnam style will be the theme for the temperatures this weekend in the Northeast.
Much milder air will be heading into the Northeast this weekend. On Sunday, temperatures are likely to be in the 50s in Boston and 60s in Philadelphia. Chicago has temperatures in the 50s today, but by Sunday and Monday, it will be in the 20s and 30s. As the cold air comes in, an area of precipitation may arrive in time to cause slippery conditions in the Windy City Sunday morning. As the cold air moves toward the East Coast Monday and Tuesday, the warmth will be erased, but we should not expect any extreme cold with this first outbreak.
Last year was officially declared as being the warmest year in the U.S. since recordkeeping began more than a century ago. Looked at over a long period, it is a slow process... in contrast to the fast changes we can experience in the weather from day to day. As it gets colder in the Northeast next week and the week after, global warming may not be the first thing to come to mind. However, as you can see in this picture, it exists.
In yesterday's report I made an analogy about predicting snow amounts using our 16 year old American Eskimo dog Sam as an example. I told Sam about it before taking this picture, but he just looked at me.
This map shows the pressure pattern around the big storm that some people in Boston and Providence are comparing with the Blizzard of '78.
In the worst-hit areas, plan for travel bans (for all non-emergency activities) because of impassable roads and extremely poor visibility. This map shows our projection for snow accumulations by early Wednesday. In many areas the heaviest snow should fall overnight and tomorrow morning.
In the worst-hit areas, plan for travel bans (for all non-emergency activities) because of impassable roads and extremely poor visibility. If you get stranded, rescue crews may not be able to reach you. Storms like this sometimes generate thunderstorms within the heaviest snow bands. The map shows predicted snow accumulations by early Wednesday.
It appears likely that many normal activities can go on through the day Monday, as long as the typical cautions for light to moderate snowfalls are observed. Tuesday will be an <strong>entirely different story</strong>. This map shows the GFS- predicted snowfall through 7 P.M. ET Monday:
The second storm we have been talking about will affect the Middle Atlantic region late Sunday and Sunday night. This GFS forecast map is for 7PM ET Sunday and shows precipitation amounts for the 6 hours up to that time.
