I’ve looked at a new site for computer model data. I think the pictures are prettier than the US Government site. No surprise there. The snow fall pictures are purple and orange for this weekend. It looks like the Flagstaff groundhogs will have a bit of digging to do to get to above the snow on Groundhog Day. In the image below, Flagstaff has a big 12 printed on it.

The colors are definitely more dramatic. The reaction to this storm from the National Weather Service hasn’t been until tonight. This storm is going to be big. It has shown up in the computer models as a big storm for a while. Just on Friday evening did they get excited.

There could be local effects causing the total to be more or less than the forecast. This is especially true with the windy start to the storm.

I don’t know if a groundhog living in Flagstaff will see his shadow on February 2. But, it will see some fresh snow. Next Sunday and Monday should be snowy. For the last few days the GFS model has repeatedly shown snow for these days. The amounts have varied. Some model runs have over 1.5 […]

I’m looking at Wunderground‘s, the National Weather Services and Accuweather‘s precipitation forecasts.

I think Flagstaff is easily going to receive a foot of snow this week. I’m not sure I buy the NWS’s forecast for the majority of it showing up at the end of the week. I think there will be two serious rounds of precipitation. First between today and Wednesday. Second, at the opposite end […]

After a drier than normal December, El Niño will get 2016 off to a wet start. The average monthly precipitation for Flagstaff in January is about 2 inches. Next week’s outlook from the GFS model at the Climate Prediction Center forecasts that amount to arrive between today and next Saturday. Multiple storm systems will move […]

December has been low on moisture compared to normal, and near normal for the average temperature. Low precipitation in an El Niño December probably is not very unusual. I’ll have to look. But, it all changes in the start of January. A series of storms is due next week. Arizona will get plenty of moisture […]

I haven’t seen any forecasts that without a high likelihood of a white Christmas for Flagstaff. As it is often the case, the exact timing and total snowfall amounts are changing in the forecast, but several inches in or around Christmas Day are very likely. The 6-10 precipitation outlook is below. I don’t see a […]

Since moving to Germany last summer, I kept hearing stories about a man in Bavaria that could forecast the long-range winter weather with high accuracy. Over lunch last week, I got more of the details. Details that leave me wondering if his forecast method could work in Northern Arizona. I can’t remember anyone mentioning it […]

2 or 3 storms are on their way to Arizona. The next two weeks will be mostly, seriously, cold with occasional snow. It looks like the storm track is shifting to the south and splitting, as we expect for an El Niño winter. More later… Tweet

Thanks to an Eastern Pacific hurricane and very strong northerly storm track, the next couple weeks will be very dry in Arizona. Tweet
