A 40-degree temperature swing in one day? That’s what some of our colder suburbs achieved today. Temperature that began the day below freezing charged to a sunny 70 degrees this afternoon. Is a repeat possible Wednesday? You bet.

Through Tonight: Skies are clear. Clear enough to easily see the moon and Jupiter less than 10 degrees apart! Temperatures drop like a rock in the colder suburbs to near freezing, but 10 degrees higher than that downtown.

Wednesday: After some morning fog, particularly in the colder suburbs, it’s another day awash in sunshine (though we may see some high cirrus clouds in the afternoon). Highs, like today, range from 65-70.

Tropics: Tropical storm Sean formed earlier today between the Bahamas and Bermuda. Currently 430 miles southwest of Bermuda, its maximum sustained winds are 50 mph and it’s crawling west northwest at 2 mph. Modest strengthening is possible over the next couple of days and Sean’s outer circulation may graze Bermuda Thursday into Friday. Sean is the season’s 18th named storm, tying 1969 as the 6th most active on record
