Summer will makes its stand by next week. The jet stream will finally lift north after its stubborn ridge pattern for over a month, which has been keeping us cool and below normal for weeks. With the jet stream shifted into Canada winds will shift into a more southerly fashion and pump warm moist air up from the Gulf. The moisture will likely be enhanced due to the heavy rains in the Southern Plains over the last week as the Gulf air mass rushes north over these areas. With that being said the humidity will be turned on, and with temps in the 90s to 100s, heat indexes will be over 100 in much of the Midwest by the middle of next week!
