This Week’s HyperCast Moments Will Make You Say Wow

From Kansas City to Houston and up to the Twin Cities, HyperCast shows off pinpoint precipitation — and it’s on every street. Plus, why it matters!

1) HyperCast tracks a Minnesota storm as it happens, while the radar layer can’t quite keep up — on June 28th, 2017 at 5:35 PM.


2) HyperCast tracks a small but destructive storm cloud over Houston, Texas on June 30th, 2017 at 11:58 AM.


3) HyperCast catches a big storm over Kansas City on July 4th, 2017 at 9:05 AM


Someone asked me this weekend, “Why do you care about seeing the weather in this level of detail? I don’t get it.” Sure, it’s cool to observe the rainbow colors of the HyperCast’s rain dots pitter pattering over the U.S., but you really see the difference once you start nowcasting.

Nowcasting is another word for very short-term weather forecasting, from one minute into the future to a few hours. Usually, to know the future weather, you need to know the weather now, and you get that information from radar, satellite, or weather station reports.

The problem is that once the information gets to you, it’s already outdated. Most of this traditional hardware doesn’t get inputs fast enough to translate into a hyper-accurate micro-weather forecast. This is why radar might be wrong 50% of the time.
