Below normal temperatures through the week. Chance for scattered rain showers Friday & Saturday. pic.twitter.com/58y82Me5ol— NWS Chicago (@NWSChicago) October 17, 2018
While not high impact, it's been a windy start to the week & will end so. Today's gusts to peak around 25 mph while Fri & Sat forecast to be at 35+ mph. Active pattern to the north is causing the winds, & systems will pass closer at week's end bringing precip chances. #ILwx #INwx pic.twitter.com/hcEOd0IbHI— NWS Chicago (@NWSChicago) October 17, 2018
More rain for flood-stricken areas of Texas, with temperatures 5-15 degrees below average in the Eastern U.S. by the weekend. We are LIVE with your local forecast and the latest on #Hurricane #Michael recovery. pic.twitter.com/18fWGdTxMg— The Weather Channel (@weatherchannel) October 17, 2018
I'm probably in the minority but I'm looking forward to this cooler weather. Get the details on the tumbling temps with @TevinWooten, @GregPostel & I...9am-1pm ET. pic.twitter.com/ViNz3cu9vF— Alex Wallace (@TWCAlexWallace) October 17, 2018
The first half of October saw warmer-than-average temperatures in much of the East but the second half will be much different: https://t.co/pbA6HuktlT pic.twitter.com/CVYd5sDUHP— The Weather Channel (@weatherchannel) October 17, 2018
Ensemble means suggest stalled front over the Gulf of Mexico next week, then upper-level energy running over the top. Could -> some locally heavy rain along parts of the Gulf Coast next week. (Images: @TropicalTidbits) pic.twitter.com/PdrivaUdhJ— Jonathan Erdman (@wxjerdman) October 17, 2018
