The High Resolution Limited Area Model (HIRLAM) is a numerical weather prediction model. It is run by the Royal Netherlands Meteorological Institute (KNMI) which is the Dutch national weather service.
On TheWeatherOutlook (TWO) a selection of charts generated from the HIRLAM model data is now freely available. The charts update four times each day and go out to 48 hours hours ahead. The data used has a horizontal forecast resolution of approximately 11km and is stepped at hourly intervals.
The initial range of charts on TWO is:

Updates on our website are every 6 hours and take place at approximately 04:00, 10:00, 16:00 and 22:00 GMT.
It is our intention to increase the amount of HIRLAM based charts and data on TWO so look out for further updates.
At the present time the charts are not available on the native Android and IOS apps but they should be included in the next release.
The HIRLAM charts on TWO are a very useful tool to help with in-depth short range weather forecasting. They are made freely available and permission is granted to:

2) Copy individual charts and use them on social media or web pages as long as it is not for financial gain. Please also credit TheWeatherOutlook as the chart source and provide a link back to our website (https://www.theweatheroutlook.com).
