OK, so it was 90 degrees on the car's thermometer at 9:30 this morning. That's danged hot. And the forecast warns of highs near 100 degrees this afternoon - AT THE AIRPORT. Downtown, on the streets, on the rooftops, it's sure to be hotter. Heat advisories are up again today for the afternoon and evening. Once again, it's going to be hot nearly everywhere across the lower 48.

Humidities, too, will be high - even worse than the relatively mild dew points in the 60s yesterday. And air quality is sure to be nasty, as well. So heed the advice coming from public health officials and stay indoors as much as possible, find a cool place to hunker down and wait it out.

Relief, of a sort, is en route in the form of a weak "cold" front from Canada. It should drop the highs for the rest of the week into the normal range for this time of year in Baltimore - upper 80s to low 90s. The front's approach could bring a few thunderstorms, some of which could become severe. In the meantime, the heat and humidity afford us a small chance of storms throughout the week.

Here, while we're at it, are some other stories about summer weather gone amok in China, South Korea, and the United Kingdom.
