Boulder, CO – The weather pattern dominating the U.S. over the next week or so is going to be one of fast-moving, consistent storms.nSometimes the jet stream (storm track) makes big dips to the south (troughs) or bulges up to the north (ridges), and this helps to create stronger, longer-lasting storms.
The next week is not one of those times.
Instead, the jet stream will generally move in a straight line from west to east, which will
not allow any individual storm to be very strong or last all that long. The graphic below shows
the faster winds colored in blues and purples, with the general position of the jet stream
noted with the thick black line.
With the jet stream across the northern third of the U.S., the northern mountains around
Wyoming, Montana, Idaho, Oregon and Washington will be favored for the most snow. Areas around Lake Tahoe, Utah and northern Colorado will also see some flakes, but accumulations will be lower.
This is one of those weather patterns where you’ll see just about all snow conditions in the span of a day or two. When the storms roll through, it will get colder, windier, and snowy. On the day between the storms, the sun will shine and the strong March sun will do a number on the snow surface (think spring skiing). And the next day – a new storm will roll in. Just lather, rinse and repeat!
The weather models are saying that a stronger, longer-lasting storm is possible in about
10 days, but these forecasts are not very reliable so we’ll just have to wait and see.
