NOAA Hazardous Weather Testbed

The NOAA Hazardous Weather Testbed is a joint project of the National Weather Service and the NOAA National Severe Storms Laboratory.

No experiment this week, but we’re excitedly preparing for @NOAANSSL’s big 60th anniversary celebration tomorrow.

It’s another active week in the HWT with the second week of the 2024 Watch-to-Warning Experiment.

HWT action continues this week, with the first week of the 2024 Watch-to-Warning Experiment.

And we’re back! After a month and a half off, the HWT is back in action with the first week of the brand-new Dual-Pol Phased Array Radar experiment.

There are 2 weeks left for NWS forecasters to apply for our late summer experiments. Applications due 18 June! https://t.co/HkbvjV3T6n

For the first time since 2019, it’s a 3-for-1 special in the HWT spaces this week, with week 2 of the Threats-in-Motion experiment, week 1 of the Satellite Convective Applications experiment, and week 3 of the Spring Forecasting Experiment all ongoing in-person.

We certainly picked an interesting day for the first time running two simultaneous in-person experiments in the HWT space since 2019. 😅 Both the Spring Forecasting Experiment (SFE) and Radar Convective Applications Experiment are listening to the SFE weather briefing.

Today marks the first time that data from @NOAANSSL’s Advanced Technology Demonstrator phased array radar are being evaluated in an HWT experiment.

Our second experiment of the season began this morning, with virtual focus groups getting to evaluate possible future changes to SPC outlooks in the Convective Outlook Innovations experiment.

And we’re off! The 2024 NOAA Hazardous Weather Testbed season started this morning with the Radar Convective Applications experiment.
