After a warm 1st half of October, much cooler weather has arrived in the city. This weekend will bring readings in the 40s and 50s. These will be the coldest readings since May. Also, on Saturday, we will have showers in the morning but it will be dry in the afternoon and on Sunday. The cooler weather is expected to linger through the next 7 to 10 days at least, so it's time to switch out your closest and take out the air condioner from the window.
