Welcome to the 5.10 Update! This update adds the RRFS model and brings a major expansion to our Australian coverage: Australian Weather Alerts, plus a revitalized Australian radar network with new dual-pol products, additional tilts, and Bureau-standard site naming. 🧵👇🏻

Heavy rain may lead to isolated flash flooding across portions of the central and southern High Plains today into tonight. A Marginal Risk (level 1/4) is in place, with repeated rounds of storms possible in the Texas Panhandle!

Fog sure does make for a spooky scene, but it's no trick on the roads! Reduced visibility can make driving dangerous. Slow down, increase following distance, and use low-beam headlights when traveling through foggy conditions.

Show us your RadarOmega setup! 📱🖥️ From your favorite radar products and color tables to custom layouts, we want to see how you make the app your own. Drop a screenshot or a photo of your setup below!

Take a different look at storm structures! The volumetric radar viewer lets you explore a radar scan in 3D and use vertical cross-sections to examine how radar returns change with height. Available to Alpha subscribers in the app!

Winter weather terminology matters! ❄️ Advisory, Watch, and Warning each represent different levels of expected impact. Knowing the difference helps you stay prepared and respond appropriately.

Don't wait for a tornado warning to figure out where to go. Identify a small, interior room on the lowest floor of a sturdy building, away from windows. Take a few minutes today to make sure everyone in your household knows the plan.

Where do North America's low-pressure systems get their start? This graphic highlights favored regions for mid-latitude cyclone development. The formation or strengthening of a low pressure system is called cyclogenesis.

It will soon be lake effect snow season, but how does lake effect snow form? ❄️ Cold air moving over relatively warm, open lake water picks up heat and moisture. Rising air helps clouds develop, which can produce narrow bands of heavy snow downwind of the lake.

Weather radar picks up more than just rain! 🦇 On June 5, 2024, radar captured bats emerging near Brackettville, Texas, shortly before an outflow boundary from nearby thunderstorms moved through. Watch the bats appear on radar as the boundary approaches!

What's your favorite weather sound? Rain tapping on the roof, distant thunder, wind rustling through fall leaves, or something else? Tell us below! 🌧️

Are you familiar with the difference between a Tornado WATCH and a Tornado WARNING? As we head into the second severe weather season, it is important to know the difference so you know what to do when a warning is issued.

Severe weather isn't just for spring! Fall's stronger storm systems can combine with warm, moist air to fuel severe thunderstorms. Damaging winds, large hail, and tornadoes are all possible during second severe season.

Ever spotted bright, rainbow-like patches of light on either side of the Sun? Those are called sundogs! ☀️ Sundogs form when sunlight is refracted through ice crystals in high-altitude clouds, creating bright spots approximately 22° to the left or right of the Sun.

Shelf cloud or wall cloud? While these thunderstorm features may look similar, they form in different parts of a storm. Shelf clouds are associated with outflow and strong winds, while wall clouds form beneath an updraft and may indicate tornado potential when rotating.

What first sparked your interest in weather? 🌩️ Was it a memorable storm, a childhood fascination with thunderstorms, or something else? We'd love to hear your story! Share it down below.

What does velocity tell us? 🌪️ Unlike reflectivity, radial velocity measures motion toward or away from the radar. Greens indicate movement toward the radar, while reds indicate movement away. This helps meteorologists identify wind patterns and potential storm rotation!

Cold, warm, stationary, and occluded: the four main types of weather fronts mark boundaries between air masses. Recognizing their symbols on a weather map can help you understand the changes heading your way!

Spring isn't the only season for severe storms! ⛈️ During fall, returning moisture, changing temperatures, and stronger wind patterns can create favorable conditions for severe weather, particularly across parts of the South. It's the second severe season!

On this day in 2015, Hurricane Patricia reached an astonishing peak intensity of 215 mph with a minimum central pressure of 872 mb. Patricia set records for the strongest 1-minute sustained winds worldwide and the lowest central pressure in the Western Hemisphere.
