8-14 day precipitation anomaly outlook from the Climate Prediction Center on December 23, 2016.

Not much has changed in the outlook. Snow is on it’s way to Northern Arizona. After a windy morning, accumulations in the 8-12 inches will mostly arrive this afternoon and evening(Storm Warning text is below the graphic). Ta-da! White Christmas!

Be very careful with travel!!!

What’s possibly more interesting is that it looks like a repeat is over the horizon for next weekend. It looks like another one-two punch is focused around New Years. One storm comes in from the west, followed by a second storm rising from the south-southwest. The current computer model projections have both bringing significant snow to the Northland.

White Christmas Storm Watch

 Northern Arizona Weather, Winter Storms  Comments Off on White Christmas Storm Watch
Dec 232016
 

Updated: Friday Afternoon, Dec 23, 2016. Winter Storm Warning

It’s almost here. But first, an admission (I mean I got something wrong, not a ticket to the movies). I got the timing wrong on the arrival of the rain in the Northland. It came earlier than I expected. I was watching the White Christmas event too closely.

And, the White Christmas will be delivered on time and in healthy form. Below is the Winter Storm Watch from the National Weather Service in Flagstaff.  Precipitation will probably come and go until it strengthens around lunch time on Saturday. From then, until Sunday morning, there will be significant accumulation of snow. If you are coming to or trying to leave the Northland for Christmas, leave before the snow begins.

Depending on terrain effects, 6-12 inches should fall on the Flagstaff area. As you can see below, Snowbowl should get much more snow.

Not a big post today. As we get closer to the weekend, higher resolution computer models are available. The White Christmas picture keeps looking better and better…assuming you will not be driving this weekend. In the higher resolution North American Mesoscale model (NAM), Flagstaff is easily in the lighter shades of red/pink. 8-14 inches of snow are possible. More and less in areas with terrain effects. Snowbowl could get 12-22 inches of fresh snow!!!

Snow Miser (Christmas Specials Wiki)

Monday morning forecasts are tricky. Everything seems to change as people show up to work and pay more attention to what’s going on with the weather and the computer models. Still, this morning, there is more agreement between the GFS and Navy models.

The Navy model shows precipitation starting on Friday afternoon and lasting at least into Saturday. It may even last through the entire day. Also, the Navy model shows easily over half an inch of water. The storm appears to be a cut-off low pressure system. The Navy seems to do better at forecasting these. Their temperature model show relatively high snow levels. I think the precipitation is most likely to be snow.

The GFS model from the Climate Prediction Center shows a storm arriving later and producing but producing similar precipitation amounts. It also shows warmer temperatures through the day on Saturday. This would limit snowfall.

We’ll see what happens. Everything seems to change by Monday afternoon.

I used the image below as the featured image. Here is a link to the page that talks about the Snow Miser. It’s worth a read, and the TV show is worth watching. I think it sums up this upcoming storm.

6-hour precipitation outlook from the U.S. Navy's NoGaps computer model for Friday evening, December 23, 2016.

I was feeling under the weather. Both because I have a cold, and the GFS computer model was not predicting any precipitation. Below is the 24 hour precipitation GFS model forecast for Friday, December 23, 2016. You’ll notice that the Arizona is covered in white, meaning no rain or snow. The rest of the intervening time has no snowfall predicted for Flagstaff.

So, I decided to check with the Navy to see if they thought the previously forecasted storm had vanished. They have a much different outlook for a similar time period. Their forecast below is for 6 hours, ending late Friday evening.

This is a much different picture. The Navy has the precipitation starting on Friday morning and continuing through Saturday morning. If the Navy is correct, there could be significant snowfall during this time.

6-10 and 8-14 day precipitation outlooks from the Climate Prediction Center, December 9, 2016)

I’m hoping I can bring some winter with me next weekend. And, it looks very much like I can. The jet stream shift continues in the computer models. The timing of the storm is Friday morning through Saturday afternoon. Here is the 24 precipitation total ending

24 hour total precipitation ending Saturday morning, December 17, 2016. (GFS Model from TropicalTidbits.com)

I used the precipitation total instead of snowfall because the temperatures will most likely be warm. The snow levels will be higher than recent storms. As a result, the snowfall picture isn’t as pretty or colorful. With the warm temperatures and high precipitation amounts, the snow could be wet and heavy around Flagstaff.

But wait, there’s more. Looking beyond next weekend, the pattern continues to breakdown. A strong system may move up from the southwest and across Arizona during the week before Christmas. It’s still a long way off. Both events are leading to great 6-10 and 8-14 precipitation outlooks.

Jet stream forecast for Saturday morning, December 17, 2016. (Tropical Tidbits)

The jet stream is pushing storms mostly to the north of Arizona. Many strong storms have recently missed Arizona, but left snow and rain from Northern California to Colorado. Currently, the jet stream seems to be stable in it’s northerly trek. Notice the reds and purples in the image below. Will this be the trend for the whole winter?

I hope not. A storm has been dropping in and out of the computer models around December 17. The jet stream will drop south across the state and move a low pressure system across the state. This should be good news.

While it is good news, the current precipitation forecast is not very high.

It’s at least a shot at a change to a wetter pattern. I’m skeptical.

Global Tropical Sea Surface Temperature Animation from the Climate Prediction Center. (23 November 2016)

Over the last week, I’ve watched the computer models bounce around. For the most part, the precipitation part of the models has calmed down to indicate two weeks of mostly dry weather for Arizona…or so I thought. The temperature models have been worse the last few days. Devastating cold and wonderful warmth are the walls the models are bouncing off. Yesterday, I almost wrote a post about how incredibly warm it would be next week. This morning, December 8 shows up in the computer models with Flagstaff 7-10 degrees below normal. By the following weekend, temperatures are 4 or 5 degrees above normal. I’m positive it will look different again tomorrow. But, why?

So, a few years ago, in a place off the western coast of North America, an anomalous blob of warm water (aka The Blob) gathered. It was following the Ridiculously Resilient Ridge. (How can a resilient ridge of high pressure, and a blob of warm water can get Wikipedia pages, and I can’t?) Both of these features interfered with forecasting because of the alterations they made to the weather patterns.

Well, the ridge is gone. Most likely this is because it ran out of ridiculousness. The warm blob is now gone, too. Not only gone, but currently replaced by a “cold blob.” The cold blob has yet to ascertain Wikipedia status. Below is the global sea surface temperature and temperature anomaly animation from the Climate Prediction Center.

Global Tropical Sea Surface Temperature Animation from the Climate Prediction Center. (23 November 2016)

Global Tropical Sea Surface Temperature Animation from the Climate Prediction Center. (23 November 2016)

You can watch the remnants of the warm blob fade away as the cold blob migrates from Eastern Russia to the east. Also, you can see the weak La Niña grow across the Equatorial Pacific. Both of these cold water features are going to make forecasting more complex. I think that’s why the forecasts keep bouncing around.

The Navy’s NoGaps forecast model has a bit of moisture in the forecast for the middle of next week. The GFS model has none, as of this post. This will be an interesting winter.

6-10 day precipitation anomaly outlook from the Climate Prediction Center on November 28, 2016

Computer models need tweaking to adjust to what’s really going on in the world. It looks like quite a bit changed between Sunday and Monday. The real timeline is probably between last Wednesday and Monday. On weekends and holidays, the computer models more or less independently produce the 6-10 and 8-14 day outlooks at the Climate Prediction Center. On normal workdays, they are adjusted by real humans. Like every Monday after Thanksgiving, huge adjustments were required.

I saved the outlooks from Sunday, and they are below.

Looks like the future storm track will shift well to the north, and oddly to the south. Flagstaff ends up in the dry middle for two weeks.

48 hour total snowfall forecast from the GFS model at Tropical Tidbits. (tropicaltidbits.com)

With 5-10 inches of snow on the way for Flagstaff, and more for other areas, what the heck do all the National Weather Service’s key words and catchy phrases mean.

Advisories mean, “Hey, there’s something you should probably keep in the back of your mind as you plan your activities.” From a kid’s point of view, a Winter Weather Advisory can mean you will most likely see snow, and have to go to school.

Watches mean, “Hold-on there, there’s a chance of some serious hazards possible over the next two days. You should consider changing your plans.” From a kid’s point of view, a Winter Storm Watch means there’s a good chance you won’t have school in a few days. It’s not sure enough to where you shouldn’t get your homework done and study for your test.

Warnings mean, “Stop, change your plans. There will probably be serious impacts from the weather.” From a kid’s point of view, a Winter Storm Warning means it’s almost positive that you won’t be going to school, but not guaranteed. Only shoveling snow will get you out of homework. The more snow you shovel, the less homework you have to do.

Okay, on the serious side, from the National Weather Service’s NWS Reference Guide:

  • Winter Weather Advisory – Snow and/or sleet and ice accumulations causing an inconvenience to society and commerce are imminent or occurring. (Specific criteria varies greatly per region.)
  • Winter Storm Watch – Possibility of accumulating snow, sleet and/or freezing rain causing severe impacts to society and commerce.
  • Winter Storm Warning – Heavy snow and/or sleet and ice accumulations are imminent or occurring. Society and commerce are expected to be greatly impacted. Precipitation may be accompanied by gusty wind. (Specific criteria vary by region)

Maybe that wasn’t clear. I looked at the NWS-Flagstaff site and couldn’t easily find their definitions for trigger points, such as 2-4 inches of snow for the Winter Weather Advisory.

Flagstaff is under a Winter Weather Advisory. I recommend full school preparedness for Monday.
