This week’s seasonal temperatures are courtesy of a transitional ridging pattern out West. The good news is that the southern jet stream could actually bring in moisture during this transitional period, October 13th-17th, offering us the best rain potential we’ve seen in awhile. Even severe weather could return this weekend.
Chilly weather returns for the latter half of the month, including Halloween, so enjoy the mild temperatures for the next week. As we head toward the end of the month, a deep trough will set up and looks to dominate the weather pattern across the eastern two-thirds of the country. This northwesterly flow leads to cooler conditions across the Midwest and Southeast. The much talked about El Niño remains weak with little effect on the overall pattern.
For the Heartland expect below normal temperatures from the 17th through the end of the month, as we will continue to have numerous cold fronts diving through the area. This will also lead to quick hitting rain chances, if we can squeeze out any moisture.
