A Biblical Storm Update

Image
 " The rain fell on the Earth four days and four nights " -Genesis 7:12 (paraphrased) I suppose its blasphemous to paraphrase the bible, but by the time the current storm is over tomorrow, it will be about a four-day event, so it seems appropriate.   Below are gauge-measured precipitation totals for the first 3 days of this storm (i.e., from 1500 UTC/0900 MDT Saturday to 1500 UTC/0900 MDT Tuesday). Many stations, even in valley locations, are over an inch.  2+ inches at many locations along the east bench of the Wasatch Range from Orem to Ogden.  Some statiions over 6" in the Wasatch Range.  This data hasn't been quality controlled and a few big amounts might need to be adjusted, but the normally somewhat reliable Timpanogos Divide and Snowbird SNOTEL stations are at 7.00 and 7.30 inches, respectively.   Source: Mesowest The Collins snowstake has about 8" of dense snow on it this morning.   Snowbird has 10" on theirs, giving them early b...

The Jet Stream Is Broken

Image
An upper-level trough is moving through Utah today (Thursday) and tomorrow, bringing with it some convective storms and eventually cooler temperatures.   Snow from the last storm is now almost gone.  The Mount Baldy webcam at Alta this morning shows the snow line has tretreated to nearly 10,000 feet with substantial losses even at upper elevations.  Although the Mt. Baldy summit is obscured, considerable rock and dirt is exposed in the Ballroom at center right of the photo.   Source: Alta.  Photo from about 7:45 AM 22 October 2026 Se, we are essentially starting over from here.  The situation for today and tomorrow is a bit of a crap shoot.  Today, snow levels will be too high for much in the way of accumulations.  Perhaps if we get a thunderstorm or thunderstorm complex today it can lower the snow levels down onto our highest peaks, but the RRFS ensemble shows the wet-bulb 0.5 level sitting over 11,000 feet until later this evening....

Fall and Winter

Image
October is a great month in Utah and this weekend has been a beauty.  Fall and winter seasons were in evidence this morning in Big Cottonwood Canyon.  Although past peak, golden aspens were still in abundance.   Then there's the snow on the high north aspects. I'm curious to see how much of that snow can survive this week.  Under clear skies, it can be hard to melt snow this time of year on shady north aspects, but the models are advertising a late-monsoon moisture surge later in the week with mild 700-mb temperatures, cloud cover, and snow levels that could be above 10,000 feet on Thursday.    That's a recipe for rain on snow to at least 10,000 feet so maybe we will lose some of that high north snowpack before the trough swings through and temperatures fall.   We shall see...
