I say it all the time, but Billings and the high Plains are the toughest part of the country to forecast for. Let’s try our luck today, shall we?
At 1153PM, MT, Billings was reporting a temperature of 73 degrees with clear skies. Eastern Montana was clear for the night, and under the influence of a fairly table upper level pattern.
Despite the ridging across the northern High Plains, there is a bit of a jet maximum over the northern Rockies, inducing some lee troughing across the region. As it has the last couple of days, this feature is expected to generate more isolated afternoon showers and storms, though most of the activity will hug the mountains. The greatest threat for Billings is that the storms will touch off wildfires that impact Billings’ air quality. A deeper trough providing the southwesterly jet streak will begin to shift east through the period. As there will be an increase in upper level vorticity, there will be an additional increase in surface cyclogenesis by Thursday. As a result, don’t be surprised to see storms get nearer to Billings, though the threat for any actual precipitation in the area will remain low, as the surface will be quite dry. That southwesterly flow will ensure it gets quite warm during the afternoon.

Hot! It’s interesting to me to see how different the various forecasts are. I am looking closely at the short range temperature forecast, as everything else (like what the NWS used earlier in the evening) is trending too cool. Here is a pretty relaxed satellite image of Montana.
