Nice weather ahead, once Earl departs

Today promises to be the 53rd day this year with highs of 90 degrees or more. And tomorrow we're still likely to tie the all-time record for Baltimore - 54 days, set in 1988.

But once this pesky Hurricane Earl goes away late Friday, there is a cold front due to sweep through. And that will bring some very cool, dry September weather to make our memories of the Beach hurricane Earl90s (the heat, not the decade) fade away. And it will clear the air of all this pollution, too.

The National Weather Service forecast office in Sterling is calling for highs this weekend in the low 80s, with sunny skies and low humidity. Overnight lows will dip into the the 50s and 60s Saturday night, and as low as the 40s in the mountains.

For now, we're still dealing with the hot weather. And the heat and sunshine, combined with smokestack and vehicle exhaust, are pushing ozone and particulate levels to Code Red levels today across Central Maryland. That's considered unhealthy for everybody. So it's good reason to avoid strenuous activity or outdoor exercise today.

The air quality alert on the Eastern Shore and in Southern Maryland is Code Orange - unhealthy for sensitive groups, including the very young, the elderly and people with chronic cardiac or respiratory illnesses.

So let's have everyone stay indoors, and track the heat and the hurricane online. Here's the scorecard on soon-to-be-matched 90-plus record for Baltimore:

Sunday:  High 91 degrees. Day 50  Matched in 1943, 1966, 1991.

Monday:  High 94 degrees. Day 51  Matched in 1941, 1995.

Tuesday:  High 95 degrees. Day 52

Wednesday:  Forecast high 94 degrees.  Day 53

Thursday: Forecast high 91 degrees. Day 54. The record, set in 1988.
