Avalanche, Alaskan Size


While avalanches are a concern in many areas of Western Wyoming during the winter months, Alaskans also have to deal with them, apparently on an even larger scale.  Over the weekend a huge avalanche buried the only land route into Valdez, Alaska.  Below is an aerial photo taken over the Richardson Highway.



Following is a Google Earth view of where Keystone Canyon is  located with respect to Valdez.



The video from a helicopter flying across the avalanche provides a true perspective of the actual size of the avalanche.

 The avalanche footage was posted by YouTube user akiwiguy101 and shot near Valdez Alaska.

More detailed information about the avalanche  can be seen at the Valdez Avalanche Center

Initial Wyoming Spring 2014 Snowmelt Flood Potential Outlook


Following is the first snow melt forecast of the 2014 Winter.


Initial Wyoming Spring 2014 Snowmelt Flood Potential Outlook---January 24, 2014

Quick Synopsis:

Mountain snowpack and associated snow water equivalents (SWEs) across Wyoming were generally above average by the middle of January.  SWEs at the peak snowmelt runoff elevations (8,000’ – 9.500’) were the highest across northeastern Wyoming at 120 to 145 percent of median; while across southwestern Wyoming, SWEs were 85 to 95 percent of median at the peak snowmelt runoff elevations.

This outlook is based on various diverse hydrological factors such as snow water equivalents (SWEs) in the mountain snowpack, basin morphology (i.e. how basins respond to snowmelt), extent of burn scars from 2012 and 2013 fires, amount of bark beetle kill, and likely temperature and precipitation trends during late spring/early summer.                                          

 
HIGHLIGHTS:

Moderate potential for flooding associated with snowmelt is expected across various headwater streams along the Powder River Drainage as well as along eastern portions of the Big Horn Basin.  Streams with the highest potential for flooding include the Middle Fork of the Powder River (Kaycee), Medicine Lodge Creek, Ten Sleep Creek (Ten Sleep), and Clear Creek (Buffalo)…

 Moderate potential for flooding associated with snowmelt is also expected along the Little Snake River near Baggs and along the Encampment River near Riverside…

…All other of headwater basins across Wyoming can expect a generallylow potential for flooding due to springtime snowmelt...

The next graphical outlook will be issued around the 25th of February.

Snow Free Days to Continue Through the Weekend

The string of basically snowless days in Star Valley as of Friday had reached 11.  With the weekend remaining snowless the string could reach close to 2 weeks in the middle of January.  Needless to say for the middle of January much appreciated by most residents.

The pattern will be changing by the middle of next week, with snow returning to the local scene.  The weekly Riverton Forecast Office discusses the next several days

Inversions Rule



Conditions are ideal  for strong temperature inversions in the valleys of  Western Wyoming with snow cover, clear skies, very dry air, high pressure and the low sun angle of January.

Here are a couple of cam view this morning of the beautiful mid winter scenes.



North View from Snow King
North View from Star  Valley Ranch
The strong ridge of high pressure which has resulted in the extended period of clear skies and dry weather for this part of the country remains in place this Tuesday morning.

 Given the still low sun angle of January and very dry airmass, even with full daytime sunshine temperatures in the high valleys of Western Wyoming, from day to day are actually gradually cooling.  Illustrating this is the weather station at Thayne Elementary School which measures the amount of solar insolation along with temperatures.

Daily Minimum temperatures and daily solar insolation for January 2014 at Thayne ES
Note that once the sunny days began on the 15th nighttime temperatures became colder reaching a monthly low of -11 this morning. 
Riverton Balloon sounding this morning illustrates the strong inversions with the warmer air above.

Riverton Radiosonde 6am 01/21/14
Just a few hundred feet above the surface the temperature is above freezing and does not go below again until around 700 mb or 10,000 feet.

Following is a map of the observed minimum temperatures for Tuesday 1/21/14 across the region

Minimum temperatures 01/21/14
Quite the contrast from below zero in most valleys to generally teens in the higher elevations.

Here is a close look at minimums in both the Star Valley and Jackson Hole regions this morning.

Minimum temperatures 1/21/14
Minimums 01/21/14
 The skiers will find slope temperatures much milder than in the adjacent valleys, both day and night.

Here are the maximums observed on Monday 1/20/14


The higher elevations afternoon temperatures are in the 40s and some 20 or more degrees colder in the nearby valleys.

The classic example of the strong radiational cooling that occurs under this regime is at Peter Sinks near Logan Pass  in North Utah.  following is the graphic showing the dramatic day to night temperature change at this location.

While a short distance to the north, no more than a mile or so, another sensor is on the rim of the Peter Sinks site where little in the way of an inversion is able to develop.

A truly spectacular illustration of micro meteorology at the extreme.  Following is a map with the two stations plotted to show their proximity  to each other.



This pattern is expected to change very little through the coming weekend, so head to the mountains if you want to warm up!

Historic California Drought

Cliff Mass, Professor of Meteorology at the University of Washington, has provided an excellent summary of the drought conditions in California.  Note also that Wyoming is doing quite well thus far.

http://cliffmass.blogspot.com/



Extreme Drought in California

California is now experiencing an extraordinary, historic drought.  2013 was the driest year on record for many California cities, and as the graphic here shows the precipitation averaged over the entire state was the driest for a record going back to 1895.   Oregon was also quite dry (4th most arid on record).  In contrast, wet conditions were observed over much of the central and eastern U.S.
The precipitation totals for all of 2013 were amazing (all in inches).  A few examples

Downtown LA 3.60
Santa Barbara 3.95
Paso Robles 1.92
Santa Cruz 4.78

All are all-time records.  I could give you a dozen more.  The total precipitation for the last three months (see graphic) shows much of California has gotten less than 1.5 inches with large areas not even getting an inch.

Snow pack in the Sierra Nevada is now at alarming levels ranging from 8% of normal in the north to 22% of normal to the south.  
 A plot of the snow water content in the snow pack for the north, central, and southern portions of the state not only show it is very low, but running lower than the worst snow pack year on record 1976-1977:

California has massive reservoir capacity and the state did get a lot of precipitation in late 2012, but the lack of rain has brought most of the reservoirs to far below capacity, particularly the critical large ones in the northern part of the State (see below). 

The big question is whether there will be any precipitation soon over California.  The models are pretty emphatic about this:  nothing during next week.  Here is the probability of getting at least 5 mm (.2 inches) of precipitation during any 24 hr period over the remainder of the month based on one of the best ensemble (many model runs) numerical weather prediction systems (NAEFS, the North American Ensemble Forecasting System).  Very low probability of getting even that modest amount.  It is even very dry over us in the NW.


The February prediction from the Climate Prediction Center (see below) is for a continuation of dry conditions over California.
The only saving grace for California is that that snow pack over Colorado and environs is above normal and thus the Colorado River, a significant water source for CA should be in decent shape.  And the huge capacity of the California's reservoirs might allow them to squeak by this year.

But this lack of  precipitation is bringing major records and is getting very serious.   This pattern of dry conditions over the the entire western U.S/southern BC. is different from the pattern suggested by many climate models for the end of the century:  very dry over southern and central CA, but wetter over the Northwest and British Columbia.

Forecast note:  the inversion over the western interior will strengthen today, but weaken greatly Saturday as clouds from a weak front approaches.   Cold and foggy over lowlands but warm along the coast (60s) and over the Cascade foothills. No rain at all in the near future, with the exception of perhaps a few sprinkles on the coast on Saturday.  No new snow.

Global Warming or Cooling or What?

The media has been having a field day with the current cold wave affecting the United States east of the Rockies.  So who do we/you believe?
I believe Cliff Mass, professor at the University Of  Washington has it right with his blog issued on the subject.



Does the Cold Wave Imply Anything About Global Warming? The Answer is Clearly No.

Long Range Forecasts: How Accurate?



With all the advance in technology and increase in computer power, combined with an insatiable appetite for weather forecasts well into the future, the question arises as to how accurate are these now available specific prognostications weeks in advance.

In particular  AccuWeather.com now makes available for every city in the United States a specific 45 day forecast.  As an example following are the daily forecasts for Star Valley Ranch through the middle of February!



So the question is how do you use this forecast in planning ahead and can it be believed.?

Cliff Mass a professor of Meteorology at the University of Washington provides a very good perspective in his recent blog on the subject.
