As a resident of the sunny southwest, I am grateful that Intellicast DOES include Mexico in their radar summaries. They don't actually have radars in Mexico, but they get good echoes from there and include the data in their reports.
Lucky thing too, because big thunderstorms can sneak up from the south in the hot summer months, and the ability to see them coming when visually they might just look like a cloudy area of sky is important. It gives us the chance to maybe leave a little early from work, and certainly if we're home to unplug anything we'd like to keep.
Then it's time to pop a brew, sit on the porch and watch the show.
You can see the report (very boring right now) here:
