What it says

Field	Value	What that means
Flight category	MVFR	Marginal VFR — ceiling 1,000 to 3,000 ft and/or visibility 3 to 5 SM.
Wind	120° at 4 kt	Direction is degrees true, as reported.
Visibility	10+ SM	10 SM is the maximum an automated US station reports; it means 10 or greater.
Ceiling	2,600 ft OVC	Lowest OVC layer, 2,600 ft above the field.
Sky	Overcast at 2,600 ft AGL	—
Temperature	11°C (51°F)	—
Dewpoint	10°C (49°F)	—
Temp/dewpoint spread	1°C	A spread of 2°C or less favours fog or low stratus forming.
Altimeter	30.03 inHg	Set this in the Kollsman window; it is the field’s current sea level pressure setting.
