Mild night was the last for a while
The overnight low at BWI this morning was a balmy 72 degrees - not terribly far from the "normal" daytime highs for this time of year. But cooler, dry air is building in from the north and west behind the cold front that's passed by us today. So we can look forward to chilly nights and more seasonable days for the rest of the week.
The low of 72 this morning was only 2 degrees short of the record "high minimum" for the date. That 74-degree mark was set on this date in 1915.
The forecasters out at Sterling are calling for a high of 84 degrees this afternoon, a darn sight cooler than the 91 degrees we recorded yesterday at BWI. It was 91 here at Calvert & Centre streets, too. The rest of the week looks partly to mostly sunny, with highs in the mid- to upper-70s. The normal highs for this time of year are in the upper 70s, so we're pretty much on the beam, again. Finally.
No windows in your cubicle? That's the sky this morning, at left, from UMBC.
Nights will be cool from here on this week. So open those windows, shut off the AC, and pull up a blanket. The forecast calls for lows in the mid- to upper-50s, which is exactly right for mid-September at BWI.
There's no rain at all in the forecast for this week. We picked up 0.39 inch at BWI-Marshall on Friday, but I don't think that's representative of what many of us saw in those downpours Friday evening.
We recorded 1.09 inch here at The Sun. Some of those bursts of rain fell at rates in excess of 0.7 an hour. They just didn't last very long. We've accumulated 2.41 inches at the airport so far in September, which is about a half-inch ahead of the average September pace. The Sun has recorded 2.58 inches.
