Fall chill in store for weekend in Baltimore

The Baltimore area is in for a third straight October day in the 80s on this Orange Friday, but a cold snap is ahead.

Highs at BWI Marshall Airport reached 81 Wednesday and 80 Thursday, with lows, respectively, of 70 and 62 degrees. That is well above the normal 70-degree highs and 50-degree lows this time of year.

But temperatures are expected to drop well below normal once a cold front passes through the region Saturday afternoon. As WBAL's Tom Tasselmeyer pointed out in a tweet this morning, the front has already passed the Chicago area, which plunged to 45 degrees this morning, but out ahead of it in Cleveland, it's still in the 60s.

Saturday could reach the mid-70s in the afternoon before the front arrives, but things will cool off quickly once it gets here and the sun sets. The National Weather Service is forecasting an overnight low of 51 degrees Saturday night.

It might be a struggle to break 60 on Sunday, with a high of 57 degrees in the forecast. With the cold comes a chance of showers, as well.

Overnight Sunday and Monday, lows could dip below 40 degrees in outlying areas, reaching the lower 40s in the city.

The early warmth this month has October running more than 7 degrees above normal with an average temperature of 68 degrees, though we are just five days in.
