Baltimore breaks 90+ degree day record

By Jason Samenow

* Drier air moving in: Full Forecast | NatCast | Early climate myths *

While D.C. is 6 days away from breaking its record for 90+ degree days (we have 62 as of this afternoon, record is 67), Baltimore has already done it. From today's Baltimore Sun:

Now, after three more days in the 90s in early September, the total for 2010 [for 90+ degree days] -- so far-- comes to 55. That beats the all-time record for Baltimore of 54 days. That one had stood alone since 1988, barely surviving threats in 1991 and 1995. Both of those years counted 50 or more days in the 90s.
The summer of 2010 saw one other hot-weather record matched. There were seven days of 100-plus readings at BWI -- two in June and five in July. That's only happened once before, in 1988.

The article is a good read, as it recaps many of this year's extremes in Charm City, discusses their impacts on human health and the economy, and attempts to put them in a longer term context.

Check it out.

Baltimore had 77" of snow last winter, compared to DCA's 56" (and IAD's 73"). Definitely a flake and bake weather year.

The Sun article noted crop losses. We were in Penna last week (Allentown-Bethlehem), and there was plenty of shortish brown corn in the field.

That was a very well written article. I disagree with one of their global warming conclusions at the end: "What the global warming component is, is if the drought starts to form, the onset is quicker, it's a little more intense and the heat waves are a little hotter,"

The "onset" of drought is simply weather and can't be any "quicker" than without global warming. But perhaps he meant to say more frequent.

As for hotter heat waves, that is debatable. There is an urban heat island factor in some of the record highs (they get adjusted for UHI when calculating global warming averages, but never for new record highs). BWI in particular has poor thermometer siting and may suffer from local heat reflection.

All in all it was a good article.
