Good day everyone!
Based on analysis of the Global Models, it appears this current winter pattern will continue over the next 7-10 days, with continuing very cold temperatures over the majority of the country, a brief 1 – 2 day slight warming, then back to extremely cold temperatures. This can be pretty much seen in the current Arctic Oscillation (AO) signal forecast, as it fluctuates negative to positive toward negative again.
The Global Models, especially the GFS, also indicate ate least 2 – 3 more very cold shots of air after this current one, which will again extend down into the Florida Peninsula. Valid dates and times are posted in the bottom of the weather graphics. Minimum temperatures on Thursday morning will reach well below freezing over the extreme North Central Plains area, especially over MN / ND / SD.
In about 7 days, models are showing an extremely cold intrusion, which should bring frigid low temperatures over the Great Lakes, Ohio and Tennessee Valley, parts of the Midwest, and over the NE and New England areas. Being a week out in the forecast however, these temperatures could change either way.
Winds and seas around the Mid Atlantic and NE regions should begin to diminish later this afternoon.
I will be keeping tabs on the cold weather regime, however will most likely only post if we have extremes as we are experiencing now, or if a severe weather threat pops into the equation, as I have research I must accomplish.
ALL graphics are linked and will open by clicking on them.
Stay warm, and have a blessed day!
