You are looking at a plotted weather map.
The circle in the middle represents the cloud coverage for that area. (for example, no shading means clear, dark shading means overcast).
The long line (wind barb) represents the direction of the wind.
The smaller lines (the twigs) sticking out of the long line represent the wind speed, usually in knots.
The numbers to the right represent the pressure.
The numbers to the left (top to bottom) represent temperature, and dew point.

The circle is around the reporting location. The flagpole shows direction. The flag indicates speed. Each flag represents a range and more flags mean higher wind speeds.

The wind arrows show the wind direction. The barbs show the wind speed. Short feathers are 5knots, long ones are 10knots, black triangles are 50knots.

in the prevalent style of warmth and chilly fronts, stratiform precipitation is got here across close to and north of a heat front (regardless of the reality that throughout mid-July, you would be in basic terms as probably to verify embedded thunderstorms).
