Late Spring Records

These are the last days of spring, temperatures are on the rise and the region has already experienced one significant heat wave, but chilly weather is not out of the question.

The passage of last night’s cool front will introduce a different air mass to the region for a day or two. Upper level low pressure reaching from James Bay to the Mid Atlantic is settling in. The result, the jet stream is taking a little dip to the south and letting some cooler air filter down from Canada.

A quick check of the Baltimore record books shows the following for record lows for the next two days:

Wednesday, June 18 ….. 48 degrees (set in 1959)

Thursday, June 19 ….. 48 degrees (set in 1954)

Records, by their very nature, are tough to break and this air mass is not a particularly cold one so the records are probably safe. It looks like the chilliest morning will be Wednesday with some low temperatures in the region possibly dipping into the upper 40s. Whether readings at BWI-Marshall get that chilly is questionable. We’ll see what happens.

For now, enjoy the pleasant temperatures and lower humidity and pollution levels. All of summer is still ahead.
