Details and Options
The 
region should define a geographic region on Earth. The 
region may be given as a combination of 
GeoGraphics primitives such as 
GeoDisk and 
GeoPath, geographic 
Entity[…] and 
EntityClass[…] objects, or individual 
GeoPosition locations. For extended geographic entities, the 
"Polygon" property is used. For point-like entities, the 
"Position" property is used.
Results encompass the box containing the geographic region.
Weather properties available for vector and stream plots include:
| "WindDirection" | wind direction in degrees | 
| "WindSpeed" | wind speed | 
Weather properties available for density and contour plots:
| "CloudCoverFraction" | fraction of the sky obscured by cloud cover | 
| "Humidity" | relative humidity | 
| "PrecipitationAmount" | precipitation amount | 
| "PrecipitationRate" | average precipitation rate | 
| "Pressure" | barometric pressure | 
| "Temperature" | temperature | 
| "WindChill" | wind chill temperature | 
| "WindSpeed" | wind speed | 
ResourceFunction["WeatherRegionPlot"]["WeatherProperties"] returns the properties for ResourceFunction["WeatherRegionPlot"].
The plottype formats include:
ResourceFunction["WeatherRegionPlot"]["OutputTypes"] returns the valid format types.
ResourceFunction["WeatherRegionPlot"] takes 
date to be given by 
$TimeZone unless otherwise specified by a 
DateObject.
 When 
date is omitted, results use the latest recorded values which can vary in age. Results are interpolated for the specific 
date when specified. Dates in the future use 
WeatherForecastData and are available up to a week in the future.
ResourceFunction["WeatherRegionPlot"] has the same options as specified plottype with the following additions and changes:
