Sunday September 19 2021

A cool front has slipped to our south and is the first signal of big changes this week. Our late summer heat and humidity will be a memory this week as the humidity is dropping, and much cooler weather is on the way.

If you are going to the Ravens game this evening, the weather will be ideal in downtown Baltimore, dropping into the comfortable 60s.

 

Ending Late Summer Heat

A benchmark for summer heat is when temps reach 90ºF, and the National Weather Service ran the numbers.

Baltimore average’s the last day of the year at that mark on  September 9. The latest day was October 23, 1947.

Here’s a breakdown for our region

This week may seem like we’ve finally turned the page.

 

When we check out the temperatures on the local maps, we can already see hints of autumn inland, and that will spread for more in the next few days, along with mid week rain.

 

Morning Surface Weather

The cool front slipping south is allowing a fresh air mass in, already dropping the humidity and clearing the sky.
