Since Savannah's METAR
isn't reporting, looking at nearby KSVN and KLHW METARs
shows light winds and high ceilings.
The primary ceiling and visibility observations used in CVA are taken from approximately 1,650 METAR
sites across the contiguous United States (CONUS) and in the U.
observations indicated that thunder was reported during only 10% to 20% of the event.
A synoptic METAR
report will normally include: station identification, UTC time, wind at 10 m above the ground, visibility, "present weather", temperature and dewpoint at 2 m, sea level pressure, cloud cover amount, cloud base heights, and precipitation.
Pilots often pull up the METAR
at their destination right before taxiing out, and might see 7SM and SCT250, and assume things will be fine.
The procedures for generating a routine METAR
broadcast are straightforward.
are color-coded and displayed in plain language format, but don't expect radar graphics--the display is too small, anyway.
ForeFlight Mobile for Apple Watch can display textual weather, including METAR
data from the Appareo Stratus ADS-B receiver.
Aviation weather services continued using their own codes until 1965, when the ICAO and WMO cooperatively established the METAR
and TAF formats and presented them at the Second International Oceanographic Conference.
But if you aren't an early adopter (or even a middle level one) and you don't have up-to-the minute METAR
reports on display in the cockpit, Flight Watch certainly will be able to provide them to you.
Remember not to use the METAR
overlay for the future--plotting current observations on the forecast map will present an incorrect picture of future conditions.
Or, you might be concerned about the requirements if the ceiling is confirmed by the METAR
when you arrive.
