To Show Weather Forecast for Selected City ( in City Selection Box ) you need to first have Templatic-AdManager plugin downloaded ,installed and activated at your sites backend.
The Service for showing the Weather forecast is provided by Forecast ( http://blog.forecast.io/forecast-embeds/ ).
The Forecast Embed is an HTML code which when used in theme will show a concise little display of current conditions, the weekly forecast, and weather alerts (if any) for whatever location you specify.

How to Use the HTML code with Templatic Ad – Manager Plugin

• First install and activate Templatic AdManager plugin at your site ( themes backend )
• Go to wp-admin -> Tevolution -> Manage Locations -> Select ‘Manage Ads’ checkbox in Activate location management for option.
• Go to -> Manage Ads -> Add New Ad .
• Now give appropriate Title to this Ad like “New York Weather” ( for New York City ) (Please Note that this code will only work for Cities added in Manage Locations section at themes backend. )
• After giving the Title, Select the Country, State and City ( Location & Map ) for which you want to show the Weather forecast.
• Then in Advertisement Settings first select the Advertisement type as ‘Code’.
• In the Next step add the below HTML code at ‘Enter HTML code’ textarea.

The embed takes a few parameters (bold text): the longitude and latitude of the point you want the forecast for, the name of the location as you want it to appear at the top of the embed, and the width of the embed (which can either be in pixels or percentage). The height is fixed at 245px.
