Live data Fetch live weather data for your nearest airport from noaa.gov. You need a working internet connection. Weather is generated automatically, once a valid METAR is received. Manual input Enter your favorite METAR weather. A valid METAR syntax is required. Core high pressure region The center of a high pressure region, characterized by descending air and hence only weak cloud development with high visibility. High pressure region A high pressure region, characterized my moderate to strong Cumulus development in the afternoon and fairly good visibility conditions. Border of a high pressure region The border of a high pressure region, in which the airmass becomes unstable and various convective and stratiform clouds may appear. Border of a low pressure region The border of a low pressure region, in which the airmass is unstable and convective clouds start to form layers and merge into stratiform clouds. Low pressure region A low pressure region, characterized by rising air, widespread formation of stratiform clouds and beginning rain. Core low pressure region The core of a low pressure region, characterized by overcast clouds, bad visibility on the ground and significant rainfall. Warm sector A warm sector, characterized by high moisture in the air and haze extending up to high altitudes, but otherwise largely convective cloud development. Fair weather A lovely day for trip to your favorite 100$ hamburger airfield Thunderstorm A hot and damp summer day with thunderstorms developing in the afternoon. Be prepared for reduction of visibility in showers and strong gusts near thunderstorms Stormy Monday You're out for an adventure? Gusty winds blowing from the west and isolated thunderstorms should be avoided. Fasten your seatbelt! Marginal VFR After the storm - limited visibility and some showers. Go or No-Go? CAT I minimum If you just got your IFR rating, this is what you are allowed to do. But can you? CAT II minimum With just a 1/4 mile visibility and clouds at 100ft, you don't see much of the runway until seconds before touchdown. Trust your instruments to stay alive. CAT IIIb minimum This is expert level. You will barely see the taxiway from the cockpit, even if you are on ground. Fog and light drizzle, freezing level at 1000ft. Early morning fog Fog developed this autumn's morning. Expect good visibility above the layer. However - getting through it can be a challenge. Stay alive for a 500' climb and you'll see the sun!
