Raw, Raw, Raw

When you combine an overcast sky, temperatures in the lower half of the 40s, and a brisk northwest to north wind, you get what I term a raw day! This is definitely one of those days. And the upcoming week has the potential to give us two more raw days, one on Tuesday and one on Friday! So no lack of action in the weather business these days!

Today the surface low heads off into the Atlantic from the North Carolina coast as it continues to wreak havoc on the Mid-Atlantic states with a snow storm of record proportion. The snow has been falling up there for the last 12 to 18 hours and will continue for several more hours bringing transportation to a halt. It is going to be a slow weekend for folks in Washington, Baltimore area with lots of snow to contend with. In the meantime, we are facing a cold northwest wind with temperatures not expected to change much today – or perhaps fall a few degrees. And no sunshine with those clouds holding tough.

Sunday I expect we’ll see a little sun by afternoon which will seem refreshing, however, temperatures will still be somewhat chilly with a high of only 47.

Monday should be mostly dry as we transition to the next storm system coming across the southern tier of the US as the southern stream remains active. Actually a short wave in the southern stream should phase with a strong upper low in the northern stream to give us another raw day on Tuesday with clouds and rain and temperatures once again holding in the 40s.

Wednesday will be chilly as we start the day off around 27 and the afternoon temperatures only climb into the mid 40s. Thursday we transition again as the next short wave in a string of these begins to get close enough to affect our weather. Like Monday, I think the day should be mostly dry with precipitation not an issue until late in the evening or into early Friday. I say precipitation because it seems likely that we could see some snow or ice. There are still model differences between the GFS and the European models, so confidence is not especially high just yet. We will need to see how this system and the forecast models evolve with it, but there certainly appears to be some potential for winter weather across parts of the Southeast US including the northern half of Alabama. Watch the video for a look at the 850 millibar temperatures.

That sets the stage for another raw day on Friday when we might not even make it out of the 30s. This is definitely a stay tuned situation!

The long range GFS modeling shows another set up for cold weather across the eastern half of the country as the winter of 2010 rolls along.

Thanks for staying tuned to the Weather Xtreme Video. I anticipate having the next one posted by 8 am or so Sunday morning. I’m headed out shortly to Joe Tucker Park in Helena for the Shelby County Amateur Radio Club’s Freezefest 2010. Hams get together for swapping/selling equipment and that is the chilly event set for this morning. I hope you have a great day, stay warm, and Godspeed.
