Skyview Weather Overview
Now that snow is beginning to fly along the Front Range it is a good time to review Skyview Weather’s winter operations.
Forecasts: Forecasts are issued Monday through Saturday, generally between 700am and 800am. Sunday forecasts are issued only if precipitation is expected on Sunday or during the day Monday. Forecasts are typically delivered by e-mail with an abbreviated version sent to pagers/alphanumeric devices (such as blackberries and cell phones) shortly after 800am. Fax updates are still available though are discouraged, as they are the slowest method of dissemination. Additionally, forecasts can be accessed on the web at www.anythingweather.com (click the client login, top right) by using your username and password.
Complete Forecast Updates: Updates can be issued at any time if the morning forecast is not on track, however, these updates are usually issued between 300pm and 400pm, in hopes of reaching our clients before leaving the office. These updates are reserved for snow amount modifications or storm timing and are distributed the same way as the morning forecasts, via email, pagers/alphanumeric devices, fax, and updated to the web. Updates are typically not issued for non-precipitation changes such as cloud cover or temperature changes.
Minor Forecast Updates: Many times Skyview Weather will issue a brief update via email and pagers/alphanumeric devices but NOT the complete forecast document. These updates may include simple "morning forecast on track", "snowfall coming to an end", or warning information that may be issued by NWS. This information is brief, and ideally suited for pager/alphanumeric devices (Skyview encourages clients to take advantage of this service, call or email for details). These updates are NOT faxed or put on the web.
Evening Verbal Update Calls: When snow is anticipated during the overnight period, Skyview Weather will call our winter clients to provide verbal information on the timing and amount of snow anticipated. Please note that if snowfall amounts are expected to be less than 1-2", these calls may not be made. Typically, these outgoing calls are made between 4pm and 7pm. It is also important to note that Skyview Weather will NOT make outgoing calls if no snow is anticipated through daybreak the next day.
Snow Reports: Snow reports are issued after every measurable snow event, with a 2 business day delivery standard, after the snow has ended. The snow totals on the snow reports are taken from various sources including NWS reports, local storm reports using local trained spotters or from Skyview’s own spotter network. These snow totals are measured from a snowboard and reflect average “grass” amounts, these totals to not include drifting snowfall or actual snow on pavement/concrete.
Personal Attention: As a client of Skyview, an important part of Skyview Weather's service to you is that you can call for an update by calling the office line at 303-688-9175. Preferred times for calling are 7am until 9pm, but we attempt to be available during later hours during snow events to answer any questions you may have at a critical time. Please note, that we are often very busy before and during the snow event, so as a result you may have to leave a brief message. Leaving a message with your name and number at off hours is especially important as it will trigger a page to our personal pagers alerting us of your message and allowing us to get back to you. Please note, if you try our cell phones, it’s best not to leave a message on the cell phone as these messages are not checked frequently, and do not trigger our pagers. As long as it is weather related we are here for you!
Areas of drought are spreading across much of eastern Colorado as a result of our precipitation deficit year to date.
The map below shows forecasted temperature deviances for December 2008. As can be seen, it is expected that all of Colorado to have above normal temperatures for the month of December 2008.
The map below shows forecasted precipitation deviances for December 2008. Normal precipitation is anticipated for south and southwestern Colorado, with above normal precipitation northeastern Colorado.
Drought conditions are expected to improve several areas of southern Colorado over the next 3 months, with no change expected other area of the state.
We almost broke a record for the latest first snowfall of the season this November. The first snow was officially the 14th with a measly 0.1" with the latest snowfall on record occurring on the 24th in 1934. If this 0.1" were not measured we would have easily broken the record since the next measurable snow was on the 29th. Monthly snow was only 1.7" which is 9.0" below normal. The snow deficit is mounting quickly as we are now 15.2" below normal snowfall so far this winter season. This November was very warm with an average high of 57.3 degrees which is 5.8 degrees above normal. The average low was 28.8 degrees, 5.3 degrees above average. I cannot remember a month this far above normal in temperature in quite some time. This month just missed out on the 10th warmest November on record by 0.8 of a degree. With the lack of precipitation there was 79% of possible sunshine with only 64% on average. The lack of snow and cold last month will likely lead to a cold and snowy December.
The official start to winter will begin on December 21st at 6:04am MST. So far this month the weather pattern has become much more active and this is expected to continue with storm systems tracking through the state every 3 or 4 days bringing the chance for snow. This December will likely be above normal in snowfall and precipitation which will help cut into the 15" snow deficit we are already facing. With the active weather pattern temperatures will likely be at or slightly below normal for the month. The shortest days of the year are in December and with the low sun angle it becomes more difficult to melt fresh snow which will hopefully lend itself to a white Christmas!
