.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Using \fIWeather::Com::Forecast\fR objects is the way to access weather 
forecast information for one specific location (city) and 0 (today) to
9 days in the future.
.PP
Each time you call the \fIWeather::Com::Location\fR objects' \f(CW\*(C`forecast()\*(C'\fR
method, you'll get an updated \fIWeather::Com::Forecast\fR object. This 
object is used to access the 10 \fIWeather::Com::DayForecast\fR objects
containing the actual data.
.SH "CONSTRUCTOR"
.IX Header "CONSTRUCTOR"
.Sh "new(hash or hashref)"
.IX Subsection "new(hash or hashref)"
You usually would not construct an object of this class yourself. 
This is implicitely done when you call the \f(CW\*(C`forecast()\*(C'\fR method of 
a \fIWeather::Com::Location\fR object.
.SH "METHODS"
.IX Header "METHODS"
.Sh "\fIall()\fP"
.IX Subsection "all()"
Returns an arrayref of all \fIWeather::Com::DayForecast\fR objects if called
in scalar context, an array if called in list context.
.Sh "day(day number)"
.IX Subsection "day(day number)"
Returns the \fIWeather::Com::DayForecast\fR object that corresponds to the day
number you provided. 
.PP
The day number can be any number between 0 and 9.
.PP
Day 0 is usually \fItoday\fR. Due to a bug (I think it is one) in the \fIweather.com\fR
\&\s-1XOAP\s0 \s-1API\s0, you may get the full forecast data of \fIyesterday\fR if you call for
day 0 just after midnight. I think this may have do something with the timezone.
I have not fully investigated this issue, yet. Please contact me, if you have!
