State Lucky Thus Far – Dry Months Ahead According to NOAA

Dry Months Ahead?Klaus Wolter, a meteorologist affiliated with the University of Colorado and the National Oceanic and Atmospheric Administration continues to promise a dry winter.  In an article today in the Rocky Mountain News he says, “I think we should count our blessings. We got lucky” in regards to the amount of moisture the state has seen thus far.

According to Wolter, the La Nina weather pattern present in the Pacific will persist resulting in storms tracking north of our state.  The good news though is that snowpack thus far is above normal statewide and even if their predictions bear out, we should be okay come summer.  Here are the latest readings as of today:

Avalanche Danger High – One Dies in Recent Days

Avalanche danger.Recent snows along with high winds have raised the avalanche danger in the high country to “considerable” in many areas according to the Colorado Avalanche Information Center.  This was highlighted yesterday when a 27 year old man was killed just outside of Vail in an area known as the East Vail Chutes.  This is the second avalanche death of the season, the first being on December 2nd in Larimer County.  In the most recent case, these skiers had done everything right including having avalanche beacons but that was not enough. 

Avalanche Danger - 01/05/08

Everyone who intends to ski or hike in the high country, particularly outside of established areas, needs to be aware of the danger avalanches pose.  Recent weather has made the conditions ripe for these events.  The Forest Service National Avalanche Center points out that nearly all avalanches that involve people are triggered by the victims themselves or a member of their party.  The good news about that is that means that education can help to reduce the number of accidents we see each year.  To learn more, please see:

More Snow on the Way!

Snow on the way!After receiving a few inches of snow in the metro area on Christmas Day (3.6 in Thornton), another round is on the way and it has the potential to be pretty bad.  At 4:56am this morning, the National Weather Service issued a Winter Storm Watch for the entire Front Range. 

It is pretty unusual for them to issue a warning this far in advance unless they are confident it is going to hit and hit pretty hard.  4 – 8 inches are currently predicted with the potential for locally heaver amounts.  With as cold as it has been and is expected to stay for the next few days, this could get ugly.  Please plan your travel accordingly and be safe out there!

A few Christmas snowfall notes, from the National Weather Service: 

It appears that there may be a new daily snowfall for Denver for Christmas Day. The data in the link below extends back to 1900.  The 2.4 inches recorded today at 6 AM will beat the 1.7 inches set in 1912.  After dusting off some old records here at the National Weather Service office we discovered that 6.2 inches of snowfall was recorded on December 25, 1894.   We also found that prior to 1905 snowfall was recorded from 8 PM to 8 PM. From Jan 1905 to May 1999 snowfall data was from midnight to midnight. Since May 1999, snowfall data has been recorded from 6 AM to 6 AM.  The snow in 1894 began around 8 PM on the 24th and ended  around 2 PM on the 25th. The data for December 25, 2007 will show 2.4 inches recorded at 6 AM.  The remainder of the snow that fell today will be reflected on the data for the December 26.  It will be for the period from 6 AM on the 25th to 6 AM on the 26th. So did we have a record or not? It all depends on how you interpret  the data.  No matter how you look at it, Christmas day 2007 will be memorable.  Click here to check the Christmas day statistics  for snowfall from 1900 to 2006.

On a related note…  When you look at the measurements for snowfall that we make here at ThorntonWeather.com, those are typically total accumulations for the day we actually received the snow, up until 9:00pm or so.  The National Weather Service standard of 6:00am to 6:00am measurements is fine but are not what most folks expect.  As mentioned above, the 6:00am measurements from yesterday showed 2.4 inches of snow in Denver but obviously more than that fell throughout the day.  We feel that providing a total measurement for the day the snow actually feel is more in line with what folks expect and think of. 

Christmas Day Snow!

Christmas is here!As the kids wake up early this morning to see what Santa left them, we are seeing a bit of a nasty storm system move across the area.  The National Weather Service has issued a Snow and Blowing Snow Advisory that will remain in effect until 5:00pm Christmas Day.  Forecast models are a bit unclear as to how much snow we can expect – anywhere from one to five inches depending on which models we look at.  The biggest problem will be the wind blowing things around and causing travel issues for those visiting folks on the holiday.  Be sure to be safe and as always, stay tuned to ThorntonWeather.com for the latest.

Meteorologist: Colorado drought still possible despite storms

Drought?An interesting article from USA Today today discusses the fact that despite the snow we have recently enjoyed, we can’t rule out drought in 2008.  In part it says:

Despite a series of snowstorms that rescued ski areas in Colorado just before the holidays and built up the below-average snowpack, experimental forecaster Klaus Wolter says there still is a possibility of drought next year.

“My experimental forecast guidance for the late winter season (January-March 2008) continues to show a pervasive tendency for dry conditions over the full domain. Half of Colorado, and most of Arizona and New Mexico appear most likely to experience a dry season, raising the specter of renewed drought in currently drought-free regions,” said Wolter.

In other words, we can’t count on the wet weather to continue.  It is important to note that while the southern and central mountains have had lots of snow, the South Platte River basin, from which the Front Range gets most of its water, is still below normal levels.  To read the full article, click here

Weather Outlook – Warm and Sun!

Melting snowmanThings are finally starting to look nice for us.  The recent series of storms is gone for us (and now wreaking havoc on the midwest) and we should be in for a nice week.  Temperatures should be in the mid to upper 40’s with clear and sunny skies all week.  Friday and heading into Saturday though could bring a change.  Current forecast models (below) show a chance for snowfall during that time period but of course this far out it is hard to say for sure.  Check back often for the latest! 

Precipitation Forecast for Saturday, 12/22

The snow is ending and the weekend should be nice.

ThorntonWeather.com recorded 8/10ths of an inch of snow so the system didn’t product much moisture. Lows Friday night will be down into the single digits. Saturday will be sunny and near freezing and Sunday we will finally truly warm up above 40 degrees. That may not last for too long though – long range forecasts show a chance for more snow toward the end of next week!

More snow on the way this evening – the third storm in a week.

SnowmanHere it comes again but this time won’t be as bad as the last two. This storm should move pretty quickly through the area tonight and into tomorrow morning. Current indications are we can expect between 1 and 4 inches of the white stuff. A lot of folks are already tired of the snow but remember that while the mountains have had a ton of snow, here on the Front Range we are still a good ways below normal for precipitation!
