A Review of Skyview Services 

As was witnessed during the very active month of December, forecasts can change with time and updates become necessary.  The weather along the Front Range of Colorado is at times to very difficult to predict and conditions constantly change.  Skyview Weather updates clients in many ways, and it is important for our clients to know what type of products and information is available from Skyview Weather.  Generally speaking, there are 5 ways that we deliver information to our clients.

First and foremost, forecasts and updates are delivered via e-mail. As you know forecasts are issued every morning with updates issued as needed if any change in the forecast has occurred.  Other details may also be passed along through e-mail, such as watches, warnings, and brief 1 or 2 line updates.  The benefit of e-mail/electronic delivery is the rapid delivery speed, though you would obviously need to be near your computer to receive the information.  E-mail typically has greater detail and is issued at the same time as the paging information.   

A second way that Skyview Weather delivers its products is via electronic devices such as alpha pagers, cell phone text messages, blackberry, and PDA type devices.  This delivery method is basically available if your device has an electronic address (typically an email type address) that we can access via the internet.  This delivery mechanism provides for rapid updates to personnel that may be in the field, eliminating the need for internet access.  Skyview constantly monitors conditions through the region, and makes updates for weather conditions through our paging system.  Daily forecasts, storm updates, forecast changes, NWS watches, warnings and more can be received this way.  This method is the most rapid way to receive updated information if you are in the field and do not have a computer available.  However, Skyview Weather is limited to 232 characters or less for these updates, so the information is short and to the point.  Please note that we are unable to deliver this information to dial in type messaging services, we do need an email or internet type address to deliver the information.

A third way forecasts are delivered is via our password protected web site.  Each morning, after the forecast is written, the web site is updated with the daily forecast.  This provides the ability to see forecasts that may typically be sent to your office while at home, which is helpful during after hours.    However, unless a full forecast update is issued, minor updates and warnings are not added to the site.

A fourth, though slower way of receiving our forecasts is via fax.  At this time, fax delivery is not the suggested method of receiving our forecast information, though we do continue to deliver via fax to support those customers that still have the need for fax delivery of forecasts.

Lastly, you can always call Skyview Weather; the office is usually open at 7am through 5-6pm.  During a significant weather event we will continue to take incoming calls well into the evening to keep you informed of the current situation and give you our professional opinion of what to expect in the near future.  During off hours a message can be made and we will be notified of a new message via our pagers and will try to get back with you as soon as possible.  The greatest benefit of being able to call Skyview Weather is that we can take care of your business needs in your specific area in greatest detail.  Please note that the most effective way to reach us via phone is to call the 303-688-9175 office number, and if we do not answer, leave a message.  Upon leaving a message, we will be paged.  We do not suggest calling our cell phones and leaving a message, many times the message is not found in a timely manner.

We at Skyview Weather work hard to ensure that you are kept up to date with forecasts and any changes that may occur. In addition, look for new services from Skyview Weather in 2008 which will include automated alerts to electronic devices that can be customized with virtually any data variable from weather stations in your area that may help you keep abreast of the current situation in the ever changing weather here in Colorado!  

If you are interested in changing or adding to how information is delivered, the best way to let us know would be to send an email to tim@skyview-wx.com .

Drought Update

Over the month of December, most of Colorado saw precipitation that was well above normal

The map below shows forecasted temperature deviances for January 2008. As can be seen, much of Colorado is expected to have above normal temperatures for January 2008.

The map below shows forecasted precipitation deviances for January 2008.  Normal precipitation is anticipated statewide for January 2008.

Little change in conditions is anticipated over the next 3 months, with normal precipitation anticipated statewide.

December Summary

      December 2007 became the 6th snowiest December on record!  Two storms produced the majority of the snowfall with the first on Christmas day and another just a couple days later on the 27th.  The 7.8" on Christmas day was the highest snowfall ever recorded for the day since records began all the way back in 1882.  20.9" for the month was the sixth highest in history, but well behind the monthly record of 57.4" set in 1913.  There were 10 days with measurable snowfall indicating that the frequency of storms during the month was quite high. For the year we ended up with 14.0" which was 1.81" below normal.  As far as temperatures go the month was rather cold with an average high of 38.2 degrees which was nearly 6 degrees below average.  The average low was 15.1 degrees which was 1.3 degrees below normal.  Despite the cold weather and frequent snows the month had quite a bit of sun with 76% possible sunshine compared to 67% which is normal.  I think we can chalk that up to most of the snow falling through nighttime hours.  This December has made up for the lack of snow in November as the 12.2" above normal for this month has helped push the seasonal total to 2.8" above normal.

January Preview

     January is the coldest month of the year for the Front Range and holds the all time record low temperature of -29 degrees set way back in 1875.  Since the month is so cold the atmosphere cannot hold much moisture resulting in relatively light snowfall on average compared to other winter months.  The average for the month is 7.7" which ranks as the 5th snowiest month of the year.  January is the 2nd driest month of the year in terms of total precipitation, but last year was an exception and we area off to a good start so far this January.  The record high for the month is 76 degrees and the record low in -29 which results in a temperature spread of 105 degrees!  Not many places in the US can claim such a dramatic difference from record highs to record lows.  We can typically expect an arctic outbreak or two with temperatures falling well below zero as well as a January thaw which already happened early this month.
