Tuesday PM update:
Everything is still on track for the most part. Front looks just a touch slower than it did this morning. I think snow will be slower to develop tomorrow morning than earlier expected. While we might get a few inches tomorrow by day’s end, I do NOT see Wednesday as the day to go skiing. Thursday should be significantly better as we’ll see most of our snow in the post frontal instability. Friday should be good as well.
Storm late Saturday night and Sunday morning continues to look good. Sunday funday?
Warm and becoming windy today (Tuesday) before big changes arrive on Wednesday. Storm system will keep off and on snow going over Utah mountains statewide on Wednesday and Thursday. Total accumulations by Friday will be 6-12″ in the northern mountains with 4-8″ in the mountains of Southern Utah. Warmer and dry on Friday on Saturday before another system is possible for Sunday.
Complicated pattern setting up and therefore plenty to talk about. Warm southerly flow will exist today before things change tomorrow. Temps today will likely top 70F in the valleys with 50s in the mountains! Winds will also be picking up throughout the day, becoming potentially strong by this evening.
Tomorrow, a cold front will move through Northern Utah during the morning hours — reaching SLC area by 8am. Snow will likely develop in the mountains by lift opening and continue through much of the day. Accumulations by the end of the day Wednesday should be 3-6″ in the mountains.
Off and on snow showers will continue through the day on Thursday with an additional 3-6″ falling. Total accumulations in the mountains of northern Utah should be in the 6-12″ range by Friday morning. Southern Utah mountains will see slightly less, but 4-8″ is likely down there as well.
Here is a quick look at the NAM forecasted amounts for the Upper Cottonwoods:
Showing up to 18″ of snow by Friday morning! Personally, I think this is overdone, but who knows….?
Because of the timing of this system, and its relatively long duration, it’s hard to pick one day that is the absolute best powder day. Wednesday should be storm day, but you’ll still be able to feel a definite crust on bottom most of the day. Thursday could be a bit deeper, but at this point it’s hard to say it’ll be fantastic as models do suggest a break in the action on Wednesday night. Friday might also be very good as it’ll have the deepest total snowfall, although most snow should have wrapped up by then. My recommendation is to just keep a very close watch on how this system evolves and be ready to pull the trigger on a sick day when the timing is right. I’ll do my best to pass along the latest developments via our Facebook and Twitter pages.
We clear out Friday and Saturday for more Spring-like weather. Models now in agreement on bringing a fast-moving system through the area Saturday night and Sunday morning. This could be good news for weekend warriors as it will give us a chance for a bit of powder on Sunday. The system doesn’t look strong, but every little bit helps.
Models bring shortwave ridging back for Monday of next week, however winds will be picking up again ahead of yet another trough that is forecasted to move in next Tuesday. This is another deep and cold system — and another very good shot for snow. We’ll keep you informed…
P.S. Whether we like it or not, the season is starting to draw to a close. If you’ve been happy with the service provided by WSF this winter, please consider donating to the cause. Obviously, waking up early and scouring Wx resources to bring you a detailed forecast takes a tremendous amount of time and effort. These discussions will always be free, however, donations do help me justify to my wife why it’s worth getting up at 5am every day to look at weather models. Even just a few bucks will be very much appreciated! Thanks again!
