It’s not a hurricane but the disruption to travel and daily routines is going to seem like one for parts of the Southeast this week.
A complex winter storm is beginning to take shape today throughout the next few days as another round of very cold air makes its way south out of Canada. This Arctic air, combined with a low pressure area forecast to form off the Southeast coast, will likely bring heavy snow, periods of sleet and even freezing rain to areas that are not used to this type of event.
Since I am not a winter storm expert, I am not going to even begin to try and speculate on possible snow totals. After reading numerous National Weather Service forecast discussions from around the region, it is clear that this storm is going to be quite challenging. The main issue is how much snow falls versus how much sleet and freezing rain. The colder the air column is higher up in the atmosphere, the more snow will fall – making total accumulations potentially over a foot in some areas. However, if warmer air runs up and over the top of the cold, dense Arctic air, then it’s more likely that sleet and freezing rain will fall, cutting down snow accumulations. The bottom line is that areas within the winter storm warning are in line to receive enough snow and ice to cause major travel issues and even power outages.
Another problem is going to be the wind. A tight pressure gradient, or the difference between the Canadian high pressure and the Atlantic low pressure, will force the wind to increase across the Southeast- especially near the coast. This is the main reason behind the possible power outages as ice and snow will weigh down trees and powerlines only to be toppled by winds reaching 30 mph or higher. Coupled with the bitter cold, this issue can be a real problem for those who are not prepared to stay warm.
I am going to provide live coverage of this event from across a good deal of southeast North Carolina beginning this evening. My plan is to have a live streaming cam set up and running throughout the event. It will go where ever I go. I’ll take it with me in my Chevy Tahoe, the same one used for hurricane intercepts. I can provide live wind and temperature readings and of course, video and audio along the way.
I will also set up one weather station out near the airport here in Wilmington to capture wind and pressure readings (sorry, no temp on this one since we don’t typically record temperature readings during hurricanes). The unit will also have a live web cam image that will be posted every 60 seconds from the site. All of the data and the web cam image will be available via our app – Hurricane Impact. I will also post occasional screen shots from the app to Twitter and Facebook to keep those who do not have access to the app up to date on weather conditions.
In addition, I will post video blogs to the app throughout the event as I travel around southeast North Carolina. I will take snow measurements from time to time and will report in to the NWS here in Wilmington with that info – including wind gusts and temperature readings. This will be an interesting change of pace since I am not used to this type of weather.
I will have the live cam up and running by early this evening from my home office in Wilmington. Then, tomorrow morning, I will head out to provide live coverage of the winter storm from around the area. You may follow the live stream here: http://www.ustream.tv/hurricanetrack
