Product Overview

This professional weather station is designed to allow hobbyists and weather chasers alike to get all of the information they need to navigate the unpredictable weather that often gets thrown their way. This kit comes with a multi sensor, a thermo-hygrometer, and a full color display weather hub that helps make sense of all of the data the sensors collect.

The multi sensor is able to measure wind speed and direction, while the rain funnel captures precipitation. To save you from having to clean or dry the funnel, it is equipped with self-emptying rain vents. It also can record indoor and outdoor temperatures, humidity, and create a “feels like” temperature that takes into account the heat index and wind chill.

La Crosse Technology V40-PRO

  • 915 Mhz transmission frequency
  • Sensor search button
  • Longer Transmission Range with Wireless sensors
  • Plan Outdoor Events with Confidence

The sensor connects to the weather hub, and provides the data above. However, the ability of the hub to connect to Wi-Fi brings up a host of other features as well. The hub can provide a 12-hour forecast as well as the chance of precipitation and the forecasted high and low temperatures when connected to the internet. The sensor communicates with the hub over the 915MHz frequency with a range up to 400 feet. The hub can search for multiple sensors, as each sensor has its own identifiable ID. That means you can get multiple multi sensors and get readings from each one in turn.

You can also use the La Crosse View app on Android and iTunes to get all of the weather information that you could ever want. The app not only pulls information from your weather center, it also can pull information from the National Weather Service. With this additional information, you get some advanced forecast information that will keep you informed about what is to come.

How Does Wind Affect the Weather?

When is one of the primary influences for weather around the globe. The way winds interact and the direction they move helps determine what weather a place will see at any given point in time. This is because when air moves it also creates shifting zones of hot and cold temperatures. These zones also carry moisture from one place to another.

There are four major kinds of air masses. These all have their own temperature and moisture content. For example, polar maritime air is heated by the water blow, making it moist and generally warm. Polar Continental Air is cold and dry in the winter but becomes warm and dry in the summer. On the other hand, tropical Continental Air is dry and warm while tropical maritime air is moist and warm. The way these air masses interact with each other creates different weather patterns.

The boundaries between the different air masses are called fronts. You've probably heard weather people talking about cold fronts or warm fronts moving in. When they are from one Mass travels towards another they can create or inhibit clouds and thus create or stop storms from forming. Sometimes when two masses Collide too quickly they can cause hurricanes, or even tornadoes.

Winds are also affected by the tilt of the Earth and its movement around the Sun. During summer in the northern hemisphere hot winds become warmed by the Sun and that creates the heat that people associate with Summer. In Winter, because the Earth is tilted away from the sun in the northern hemisphere, the air and Waters become cooler. This has an effect on how warm and cold fronts are created and interact.

Wind is also closely tied to barometric pressure. That is because as wind pushes air towards a mountain range, that air is pushed upwards. As the air is pushed upward it becomes cooler. As it becomes cooler it wants to sink which increases barometric pressure in that area. Likewise as wind pushes are over a mountain and into a valley, as the air gets closer to the ground it begins to warm up. This newly warm air then wants to rise and decrease is barometric pressure in an area.

The way wind interacts has a huge effect on weather systems around the world. With the way that warm fronts and cold fronts collide, they produce every type of weather that we experience. Learning and analyzing how wind patterns and air masses interact is one way that meteorologists form predictions for local areas.


This is a great weather station that will give you all the information you could desire, whether you’re looking to plan the weekend or you just want to know about the rest of the day. With the “feels like” indicator, you’ll know how to plan your clothing; whether you should bundle up thanks to some extra wind, or if the humidity calls for lighter layers. With the app you can get even more information, as much or as little as you like, with the ability to deep dive and analyze to your heart’s content.
