Denver Blizzard Live Blog

1:53 P.M.

In brief: 

So for temperatures with this storm….you wouldn’t believe that most models are going say is it going to be in the 50s tomorrow. That’s right, I SAID 50. So, I would say expect A LOT of flooding and the wet sloppy snow tomorrow. High should be in the 50-53 range. Low will be in the 20s.

I’ve also read the latest forecast from the national weather service. They say the blizzard warning (it’s a warning because it is happening right now.) will be in effect until tonight. Snow totals expected to get up to 2 feet in some areas.

In-depth: 

First let me say how dissatisfied I am with the graphics card for my modeling software. It sucks!

Now that that is over, let’s talk temperature and snow depth. Since my graphics card sucks, I mostly have MOS products offered by the national weather service. And here is what they say for temps tomorrow:

GFS MOS: 51/25

NAM MOS: 52/25

GFSX MOS: 51/25

Short to say, with a higher temperature like that, it is going to get really wet and sloppy and gross for tomorrow. I’ve been shoveling outside in preparation for the melt. Considering if has exceeded a foot here and we can now only describe the height by if it is taller than my dogs or not.

Which brings me to snow depth….as mentioned above the NWS is predicting approximately 2 feet in some areas. I wouldn’t be surprised if it is at 18 inches at my house. Needless to say, this has been crazy at least. As someone who has only lived in Colorado for 3 years now, this is the most I’ve seen in the state since then. My husband who has lived here all his life says it is close to the blizzard of 2003.

It is A LOT!

So right now, not a lot to say anymore about tomorrow. If anything changes I will keep you posted.

11:50 A.M. 

In brief: Winds will continue on the Eastern side of Colorado until about midnight tonight according to the latest model run. This information also tells us that most of the stormy weather will be on its way out overnight.

ALSO: Traction laws are in effect for Denver-Metro area. You have to have chains, all wheel or 4-wheel drive or some kind of traction tire in order to travel around town. For more info about the laws click here.

The in-depth version: 

Pressure Map

So, besides when the wind is going to leave, I wouldn’t be doing due diligence without telling you about the wind. Up above is the latest model run of the HRRR of pressure reduced to sea-level pressure.

To non-meteorologists, that may be unclear so let me explain. Pressure reduced to sea-level pressure means I am plotting the pressure at the surface. However, pressure is different at different elevations so how do I compare pressures at different locations. The answer? I use a formula to take any pressure reading and convert it into what it would be at sea-level, thus I can compare.

Now, what the heck does pressure do with the winds. The map above and the squiggly lines show me equal lines of pressure (a line telling me where the pressure is the same). The closer those lines are together, the higher the winds.

So in the picture above, you see how close the lines are together in that bulls-eye, over Colorado, that means, well the obvious, that it is really windy (it is hard to see here but that bulls-eye is over Nebraska, Kansas, Colorado, Wyoming, Missouri, Oklahoma, Texas and New Mexico.). Unlike over Texas and Oklahoma where they are more spread out.

What I do to track the storm to see when the winds could potentially leave is watch the lines get farther apart. Which in the picture below (time stamp is cut out. Sorry guys) won’t be until mid night tonight.

So hunker down. It’s going to be cold for a little longer.

HRRR Run

Good very snowy morning to you.

If you live in Denver, I do not have to tell you about the blizzard outside. A snow storm developed overnight over the area leaving up to more than a foot in some areas.

I’ve looked at all the surface observations in the areas. The highest wind speed and gusts recorded happened just a half hour ago at Denver International Airport with winds at 41 mph and gusts above 50 mph.

That being said, I just heard that Denver International Airport is at the moment CLOSED.

Here’s what I can tell you about the future of this storm. According to the latest HRRR model, the storm will leave our area later tonight. The photo above shows that the last bit of the storm will leave our state after 5 p.m.

I will delving more into the forecast throught the day. Keep it here for more information or on my social media pages.
