GFS MOS MAV
The MAV report is a short-range forecast (6-72 hours) based on the Global Forecast System model output and is only valid for ICAO stations in the United States, Puerto Rico, and US Virgin Islands. Reports are published every six hours starting at 0000 UTC.
class avwx.Mav(code: str)
The Mav class offers an object-oriented approach to managing MOS MAV data for a single station.
Below is typical usage for fetching and pulling MAV data for KJFK.
>>> from avwx import Mav
>>> kjfk = Mav("KJFK")
>>> kjfk.station.name
'John F Kennedy International Airport'
>>> kjfk.update()
True
>>> kjfk.last_updated
datetime.datetime(2020, 4, 20, 1, 7, 7, 393270, tzinfo=datetime.timezone.utc)
>>> print(kjfk.raw)

The parse and from_report methods can parse a report string if you want to override the normal fetching process.
async async_update(timeout: int = 10) -> bool
Async updates report data by fetching and parsing the report
Returns True if a new report is available, else False
code: str
Station ident code the report was initialized with
data: avwx.structs.MavData = None
MavData dataclass of parsed data values and units. Parsed on update()
from_report(report: str) -> avwx.Mav
Returns an updated report object based on an existing report
issued: date = None
UTC date object when the report was issued
last_updated: datetime.datetime = None
UTC Datetime object when the report was last updated
parse(report: str) -> bool
Updates report data by parsing a given report
raw: str = None
The unparsed report string. Fetched on update()
service: avwx.service.Service
Service object used to fetch the report string
source: str = None
Source URL root used to pull the current report data
station: avwx.Station
Provides basic station info
units: avwx.structs.Units
Units inferred from the station location and report contents
update(timeout: int = 10) -> bool
Updates report data by fetching and parsing the report
Returns True if a new report is available, else False
