Skyview Weather

A New Lightning Warning System

New this year Skyview Weather is developing a new piece of equipment, a lightning warning/notification system.  The system consists of warning horns and a flashing strobe light that can be mounted on a pole, clubhouse roof or on a building wall.  The warning system is activated by phone through a relay switching system, allowing Skyview Weather to provide lightning warning information to locations without an office or full time personnel.

Skyview Weather will monitor weather conditions and storm development, and utilize the National Lightning Detection Network to locate cloud to ground lightning strikes.  When a strike is detected at a predetermined distance from the site, Skyview Weather will phone the system via telephone, triggering the horn and strobe lights.  Warning horns will sound for 30 seconds, and the strobe will continue to flash while the lightning threat continues  When the threat has passed, another call is made to the warning system to deactivate it, again triggering the horns for 30 seconds, and turning off the strobe.

We feel that a system such as this would be perfect for ball fields, swimming pools, and parks where numerous games and other outdoor activities occur.  Umpires or other personnel would be instructed to suspend play when the horn sounds and strobes light. Signs will also be posted alerting the public as to what the horn and strobes indicate.

Skyview Weather will begin testing this new system in Douglas County this spring.  Call Skyview Weather at 303-688-9175 for my information or to schedule a demonstration.

Weather Stations

Most people know Skyview Weather for its timely and accurate weather forecasts, but Skyview Weather also carries a fully operational weather station.  The weather station is one of the most complete on the market.  Not only does is measure all the important weather parameters such as temperature, humidity, winds and precipitation, but with the included software, data can be stored and displayed on the web.  With a web cam, images from your location can also be displayed on the web.  Sensors mounted outside, with data wirelessly sent to the computer system inside for display on the receiving computer’s screen.  With the wireless feature, installation is simplified, with no wires to run, nor holes to drill.  The software will automatically connect to the internet and updates your information at regular intervals.  The installation of weather stations provides valuable information to Skyview Weather and others, and can be invaluable with regard to heavy rains, high winds, or hazmat situations.   Contact Skyview Weather for more information on the wireless weather station.

Online Forecasts Available Again

Skyview Weather is happy to announce that online forecasts and snow reports are again available on our sister www.anythingweather.com website.  Forecasts and snow reports are password protected, but an email to Tim@Skyview-WX.com requesting your forecast and/or snow reports be available online will result in an account being setup for you.  As always, forecasts and snow reports are for client use only, but with the online access, forecasts and snow reports are just a click away from any computer with an internet connection!

February Preview

February has a reputation as a rather grim month in many parts of the country.  However, that is not usually the case in Denver.  Even though it may not be grim, it is still winter with below freezing temperatures occurring almost every night.  Snowfall for the month averages 6.3 inches, making it the 6th snowiest month.  February stands out as having relatively uneventful weather and joins September and October for the quiet months of the year.  February is a transitional month between the occasional severe cold of mid-winter and the spring storms that are common along the Front Range.

Many times during February we enjoy plenty of sunshine and temperatures in the 60s giving Denver residents a false sense of spring.  The month of March usually dispels most thoughts of spring though.
