February and Early March 2019 in Montana

Forecast for February and early March for Billings Montana couldn’t be more wrong. Second coldest February on record and third snowiest. March 2 and 3 had record lows (-19) for Billings. In fact, Billings has been ~ 20 degrees below normal for over a month.

Weather in Central Montana Feb 2019

Well, I think you predicted this one all wrong for central Montana Feb. 2019 - It has been nothing but COLD COLD COLD and snowy and windy. I hope your other predictions for the rest of 2019 are more accurate.

Travel plans Mid March

March can be an odd month in CO and surrounding states. I need to drive from Colorado Springs to Dallas Tx,
In mid March. I’m wondering if we will get one of those snow storms and should not drive, I don’t want to get stuck, I’ve heard scary stories for this time of year.
Thank you
I really enjoy finding the Farmers Almanac again

Weather, end of March 2019

Driving from black hills south Dakota to Bozeman, mt through Montana, then south and west to boise,Idaho, then west into south Oregon to Grant's pass and into crecent city ca. And then back to black hills at end of March. Is there prediction of bad winter roads and weather?
