Mercury hits 91 at BWI, downtown

Heat BaltimoreThe official thermometer out at BWI Thurgood Marshall Airport has reached 91 degrees this afternoon, making this the hottest day of the year so far, and the third that's hit the 90s. The first two were back on April 6 and 7, when we topped out at 90 on both days, setting or matching records.

The afternoon is still young, so we could go higher. But at 91 degrees we are still a few degrees shy of the record of 94 degrees, set on this date in 1914.

It's also 91 here at The Sun, Calvert and Centre streets. Tomorrow's forecast calls for a high at BWI of 88 degrees, dropping to around 70 degrees on FRiday and Saturday.

Last year BWI saw three April days in the 90s, but none in May or June. July and August produced 10 days with highs of 90 or higher.

The hot weather has produced a rash of Pest calls today. Through out the Baltimore Metro we have fielded hundreds of calls for emergency service. Yet another certain indication of the link between weather and insect activity.

nice cool and mild 84 degrees today in Las Vegas, after 28 years in Baltimore County i dont miss the weather, i got to miss the 3 snow storms too!

What happened to the Sun's almanac data on temperatures and precipitation? Gardeners and weather buffs like to track rain and degree day totals from month to month and year to year. Paul

FR: It's coming. I'm told the BWI data should be available in a couple of days. In the meantime, there is still the paper version. You can also get downtown rainfall data from The Sun's weather station, at
