It still doesn’t look like there’s much of a chance of any showers as we go through the weekend. Temperatures will spike on Friday (into the low 70s) ahead of a weak cold front which will kick up some brisk winds in the afternoon, but most of the precipitation from the front will likely stay to the north of the Reno area. Temperatures will drop Saturday into the low 60s and will fall a bit more into the upper 50s on Monday as another weak cold front passes through Sunday night.
So why does 65 on a sunny day feel so much warmer than the same on a cloudy? The sun can heat you up in two ways. First (and this is how it heats thermometers that read that 65 degrees mentioned above), the sun can heat the air, either directly or indirectly, and then the air transfers that heat to your body by direct contact. That’s called heat transfer by conduction. But the air isn’t really that efficient in conducting heat. But the sun does have a secret weapon when it comes to heating things up: radiation. More on this tomorrow.
