Well, a small chance of scatter showers looks pretty good now. But, the reality is that we won’t see much precipitation. For most of the Easter Weekend, we will have clouds and cooler temperatures and occasionally light rain. It’s very dry out there.
I haven’t written much lately. Mostly because our weather continues as mostly unremarkable and harmless. As warm and dry as it has been, we haven’t really set any significant records. This morning, our temperatures are in the mid-40s, roughly 20 degrees above normal. The next few days should have low winds, and plenty of sunshine. Next weekend, we have some showers.
Looking way out, there may be a chance that next winter will be a strong El Nino winter. Don’t hold your breath.
The computer models don’t agree and are not even consistent between runs. It looks like an April Fool’s Day joke. Back in 1999, we had a similar experience. Beautiful, above average temperatures and sunshine were in the forecast for April 1. On the afternoon of March 31, it started to snow. I remember because my wife and I were buying a used Ford Bronco that afternoon. It snowed for the next 4 days. You can review that week at Wunderground. Temperatures dropped into the 20s and stayed there. Stay tuned.
It’s been windy lately, which is typical for spring time. Yesterday, it was very windy. I usually don’t look at wind that much. But yesterday was superlative. From the National Weather Service:

Last weeks storm provided some needed relief to many parts of Arizona. We didn’t get as much as expected. There is a chance for another bit of rain on Friday or Saturday. It isn’t steady in the computer models. But, the Climate Prediction Center posted a new one-month outlook.
Unfortunately, the Climate Prediction Center based this chart on the last storm being a bigger hit. So, we shouldn’t expect much more. From the discussion notes:
THE AREA OF FAVORED BELOW-MEDIAN PRECIPITATION HAS BEEN REMOVED AND THE FAVORED
ABOVE-MEDIAN PRECIPITATION AREA IS SHIFTED CONSIDERABLY SOUTH ACROSS THE
SOUTHWEST. THIS CHANGE REFLECTS IMPACTS VERY EARLY IN MARCH RATHER THAN ANY
CONFIDENCE IN A LONGER TERM PATTERN CHANGE OF WHAT HAS BEEN SO FAR A DRY WINTER
IN THESE AREAS.
The radar summary below from Intellicast tells the story. As band of rain and thunderstorms moved across the state, they were too far south. I don’t know about how you feel, but I don’t like being stuck in the middle between storm paths. There isn’t much more in the next week or so. Sorry.
As expected, temperatures around Flagstaff are warm this morning; in the upper 30s and low 40s. The outlook for snow is pretty weak because of the high temperatures. However, Arizona Snowbowl could receive 2-3 feet of new snow with this storm. The National Weather Service hasn’t posted any alerts, yet. If temperatures drop, our outlook could change.

Thursday will usher in a wetter pattern. With the “polar vortex” moving into the Midwest and Eastern United States, our temperatures are going to stay warm until the weekend. We probably won’t see significant precipitation until Friday night. While the precipitation will continue until Monday, the intensity will drop during the day on Sunday. Since temperatures will be warm, I don’t know how much of the precipitation will fall as snow.
There will be a significant amount of moisture with this system. Here is the 5-day precipitation outlook from the National Weather Service’s Weather Prediction Center. Notice the 2.5 inch peak precipitation amount. This won’t make up our 4 inch precipitation deficit to average since September, but it could nearly cut it in half. On another note, this storm will proceed to the east. It could be come a major spring storm.
As we closer to the start of March, the storm track shifts to the south. A couple of storms had faded in and out of the models. Currently, the GFS and NoGAPs models for Saturday, March 1, align and show moderate storm moving quickly across Arizona.
Below is an image for the GFS model run by the National Center for Atmospheric Research. It shows up to half an inch of water falling around the Flagstaff area next Saturday.
We still have a week, so the outlook could change.
As most of the world seems buried in snow, Flagstaff and Sochi are basking in the sun. The East Coast is getting beat-up again today by another major winter storm. We shouldn’t see any snow for a while. We will see lost of sun courtesy of our friendly local high pressure system. Over the next few days, our high temperatures will climb from about 50 degrees today to the mid-60s for the weekend. Most of the records for this time frame are in this range. Wednesday’s is a bit lower at only 58. It could be close or we could easily blow past a couple.
Wednesday, February 12 58F Thursday, February 13 68F Friday, February 14 64F Saturday, February 15 65F Sunday, February 16 70F
Below is the temperature anomaly outlook for the next 3-7 days. New England suffers while the Southwest has an early taste of spring. Arizona is comfortably in the 15 degree F above average region. This could change at the end of next week.
UPDATED: 5:45pm AZ time – See below
The Weather service is being clear about their expectations for the end of the week. On their forecast, they have Thursday night as the period with the heaviest precipitation. This is their Weather Story for today.
But the North American Mesoscale(NAM) model has us drawing a blank for the next few days. The lower resolution GFS model shows a situation similar to the Weather Story above. Aaarrrggghhh!
2-5 Inches is probably a good guess. At this point, 4-8 seems like a stretch. The computer models are often and by large amounts. We’ll see. It’s possible the next few days could be just like the last few.
UPDATE - So, just to make the point…. The NAM model has shifted tonight. We are back in the 3-8 inch range for snowfall amounts between now and midday Friday. All I can say is “Be ready.” It will probably snow. We may receive a decent amount.
