This is helpful for picking out snow/mix/rain transition zones In all snow situations, dBZ values of 40 indicate 3-4”/hr snowfall rates and whiteout conditions. Anything larger than this is usually due to “bright banding” where the radar is seeing the part of the atmosphere where snowflakes are clumping together and melting into raindrops.

In cold climates during the winter months, actual dBZ values rarely exceed 40.

This is your standard radar data that shows precip or other solid/liquid particles in the atmosphere. The first type of data currently available is reflectivity. We currently have two types of radar data available with plans to add more soon. Use radar data with caution especially if your area of interest is far from the nearest radar location! A lot can happen between 0 and 5,000 feet and therefore the depiction of precipitation given by radar may differ some from what’s actually happening on the ground. Because of this phenomenon, the radar beam will only see precipitation falling through the mid levels of the atmosphere. To see this in action, imagine a circle (earth) with a straight line emanating from some point on the circle if you continue this line out into space, it will gradually get farther and farther from the circle. Because the earth is round and the radar beam is flat, the farther away from the radar tower the beam (energy) travels, the farther removed from the ground becomes.

There is a notable constraint to radar data though. This is the highest resolution radar data available which enables you to see features such as sea breeze or outflow boundaries that standard resolution radar entirely misses. This data is gathered from over a hundred radar towers located across the US.

Weather history and weather records and averages are used to determine the climate of a particular part of the world on a certain day in history or average over the course of many years of recorded weather history.

In addition to weather forecasts are ozone levels, changing climate conditions, global warming, El nino, and solar winds. If you are in the path of a storm you should be following official local weather sources for your area.Ĭlimate is the common, average weather conditions at a particular place over a long period of time. The tropical cyclone forecasts presented at this site are intended to convey only general information on current storms and must not be used to make life or death decisions or decisions relating to the protection of property. Since travel and outdoor activities are severely curtailed by heavy rain, snow, hail or fog, weather warnings can be very useful insuring the safety of human life. Severe weather events such as a tornado, tropical storm, hurricane, cyclones, lightning strikes and extreme weather affect us all. It is the goal of to promote public safety and save lives using reliable weather forecasts, weather maps, and storm tracking.
