Is This Arctic Blast Ending?

Strong arctic air brings another cold night to the region. Find out how the pattern looks for the long term...

Subzero temperatures are expected for much of the region tonight as clouds continue to clear and radiational cooling takes affect.  If you are sick of the cold, there is some good news with the forecast for the end of the week!

Here is a look at the forecast for around dawn tomorrow morning, at the 850 mb level...


This is when we will see the coldest temperatures of the next 24 hour period, with -20°C air pushing in overhead. At the surface, most areas will sit several degrees below zero, with areas of Ohio even reaching near -9°F! This is extremely cold air settling in, so you will need to allow time to warm up your car tomorrow morning.

The good news is that this extreme arctic air is looking to retreat for the next couple of days...


Notice how the dark red color (which indicates -20°C air) is nowhere to be seen for the next few days. In fact, by Saturday temperatures at 850 mb are forecasted to climb near 10°C, which would bring a surface temperature of about 45°F to even 50°F!

Looking further out into the forecast, it seems that this dreaded -20°C air will remain to our noth until February 11th...


The magenta colored line cutting through S. Ohio and West Virginia is the -20°C isotherm (for 850 mb).

So when temperatures warm late this week, keep in mind that the arctic air isn't gone for good. I have a feeling this will be a long winter...
