help me understand what happened
Yesterday Wednesday around 14:30 and 15:30 there was a storm in my city.
I would like to know what these options that I marked with the arrows mean.
That seems quite obvious
hPa is the pressure unit used for measuring the atmospheric pressure. In your screenshot the pressure was 1011 hPa, which is equivalent to 1011 mb (millibar). hPa have replaced mb in international units system.
The vertical scale in km and in flight level (FL rated in feet) is the altitude for the clouds shown in the panel (based on relative humidity). The first figures column (not shown in your screenshot) is the altitude expressed by pressure in hPa, shorten in h.
The last line is useful for flight. It is the cloud base height above ground.
@idefix37 How do I know the wind will be strong? do you have any scale?
How to identify a hailstorm?
When I'm observing INFRA+, I notice when I see the radar, this white part, it's causing rains. I wanted to know if the blue and red will give heavier rains or storms?

‘How do I know the wind will be strong? do you have any scale?’
You may refer to the Beaufort scale which gives the effects of wind on the land, as shown here in ‘land conditions’ column:
But this scale is more useful at sea because it is based on the averaged wind over 10 minutes, which is given by the Wind layer in Windy.
On the land, specialists prefer to use the gusts in order to evaluate the risk of damages by the wind. Select Wind gusts in Windy.
Between 80 to 100km/h, gusts are considered potentially dangerous, and from 100km/h and over, really dangerous causing a lot of damages (roofs, trees…)
