14 day weather forecast

This plot displays the 14 day temperature forecast for your selected location, Roundelay.

The red numbers show the expected high temperature for a given day, while the blue numbers show the expected low temperature. Because forecast uncertainty increases with time, we also display the range of possible high/low temperature outcomes, shown as the shaded red/blue regions. The actual high/low temp could fall anywhere in that shaded region, and the larger the shaded regions are, the higher the forecast uncertainty is.
