Part of the met office aviation briefing service is the F215 UK low-level forecast chart. To get to the F215 you will need to sign up/register with the met office aviation briefing service. This is free just google “met office aviation briefing service”. Once you have access navigate to Briefing Charts and then Significant weather (Low Level) % Spot winds. Over on the top left side, you will see F15 select the time frame.

I believe most explain itself, let’s select zone A and break it down.
Let’s just focus on zone A
Surface vis and wx is 40 KM. Below we have the weather
OCNL 6 KM SHRA/(RA FRONTS) |
Occasional 6 KM visibility Shows rain and rain fronts moving in.
ISOL (OCNL THROUGHS) 3000 M +SHRA |
Isolated occasional throughs visibility 3000 Metres Heavy showers and rain.
In very brief terms a Through is: A trough is an elongated area of lower air pressure. Since pressure is closely linked to wind, there are often changes in wind direction across a trough. You can see it in the image at the top right.
ISOL ( 2500M +TSRAGS |
Isolated visibility of 2500 Metres and Heavy thunderstorms rain and small hail.
ISOL 300 M +SHSN MON NORWAY |
