Snow Chances in the Next Week?

There may be quite a bit to talk about weather-wise over the next week. It's quiet for now, with southwesterly breezes boosting temperatures close to 60 tomorrow afternoon, ahead of the next cold front. The chill behind the front will produce afternoon readings in the mid 40s on Friday. Then another disturbance in the northern stream will throw its energy to a developing system off the coast this weekend. This coastal low will be too far east to bring us any precipitation, but the upper energy transferring to the coast may be enough to trigger some morning snow showers here on Sunday.

A more significant event next week...

What's more intriguing is a storm that is likely to affect the East Coast the middle of next week. By later Tuesday, a developing low across the south will spread moisture into our area. There will be mild air ahead of this system, so expect rain to arrive by later Tuesday. What happens after that could be rather interesting. Take a look at the latest European model run showing the surface low off the Carolina coast by early Wednesday.






















The GFS (American) model shows the low tracking off the coast as well, but a bit later. The following map is effective Wednesday evening at 7 P.M. This could potentially bring a change to snow, with colder air oozing in from the north and west. The big problem for winter weather lovers is the lack of a cold high to the north.

















The upper level pattern shows a trough going negative over the area, but will everything happen in tandem to create the necessary conditions for a change to snow? That is very much up in the air, and climatology doesn't really favor it. However, it will be interesting to watch how this situation evolves on the model data over the next few days. Stay tuned...
