Winter Storm to Track From the West Coast Across the Upper Midwest & Northeast Through this Weekend

A Pacific storm will bring strong winds, heavy rain, and mountain snow from the Sierras to Rockies on Friday. The storm will then track east through the Midwest producing heavy snow from the Dakotas to the Great Lakes on Saturday. An icy wintry mix is expected across the northern Mid-Atlantic states Saturday night. Heavy snow will likely impact the Northeast Saturday night into Sunday. Read More >

After several days (and weeks in some areas) of warm, spring-like temperatures and dry conditions, a return to wetter and cooler conditions can be expected by early next week.

For much of February, the weather across eastern Utah and western Colorado has been dominated by a stubborn ridge of high pressure centered over the Great Basin. This has acted to deflect (or move) most of the active storm track well north of the area. The persistent ridge is expected to breakdown or shift east late this weekend, opening the door for a series of wet Pacific storms to pass through the western states.

This shift to a wetter and cooler pattern can be seen in the latest 8 to 14 day outlooks from the Climate Prediction Center (below) with several signs pointing to this changing weather pattern. This should allow us to shift back into a more progressive and wetter period as storms pass through the Great Basin and across our region. This would also bring an increased probablity for wet and cooler conditions beginning on or around March 8 for eastern Utah and western Colorado. While we await the arrival of this more active weather pattern, take a look at this blog titled, "Is El Niño AWOL?. There are a lot of factors that play into our day-to-day weather and this blog helps explain a few of the reasons conditions may be drier or wetter than expected during an El Niño pattern.

Latest 8 to 14 day precipitation outlook for the United States. This graphic shows an increased probability for above normal precipitation centered near Reno, NV. In addtion, much of the western U.S. is painted "green" and points to the shifting pattern and the breaking down of the persistent ridge of High Pressure.

Latest 8 to 14 day temperature outlook showing the probability that the temperatues will be above, below or near normal. Here we can see a pocket of cooler conditions possible across the Southwest U.S. This is something we would expect to see in such a pattern shift toward a more progressive and wetter period. Even though western Colorado is mostly in the 'normal' area, the trends are headed toward a cooler period.

Of course, all of this may change now that we have mentioned it, so be sure to check back throughout the week for additional updates!
