How Canada's Wildfires Are Warming the Stratosphere 0823
As Simultaneous Crop Failures Threaten Food System Collapse, Plutocrats vs Us 0723 - Falling temperature contrast between the tropics and the polar region weakens and slows the "polar" jet stream (~40-55°N). So meanders are larger and more frequent in the north polar jet stream, leading to longer and hotter droughts, as well as longer rains and floods. These can decrease crop yields in North America, Europe and China simultaneously. The threat is worldwide famine.
‘Virtually Certain’ Extreme Antarctic Events Will Get Worse without Drastic Action 0823 - Some of them will affect the south polar jet stream, in somewhat similar ways to the north polar jet stream. Problem for crop yields in southern South America, and -somewhat less so - in Australia and New Zealand, south Africa, and temperate South America.

Climate Change in the Midwest - UCS 0809 - PDF, 24 pages
Average summer temperatures and rainfall for 1961-90, 2010-39, 2040-69 & 2070-99.
Red is for the high emissions scenario, orange for the low emissions scenario.
Northeast
Weather changes in other parts of the US (and the world) will be broadly similar to those projected for the Northeast. By 2100, places in the Northeast would get 50-60 more days over 90°F and 3-20 more days 100°F. A larger fraction of rain would come in intense events (days with more than 2 inches would rise 40-50%). 1-3 month droughts would double, 3-6 month droughts triple, and droughts longer than 6 months quadruple. Winter days with snow on the ground would fall to 1/4 to 1/2 as many as now.
Migrating Climates in the Northeast & Their Impacts - UCS 0707 - PDF, 160 pages
The UCS maps of migrating climates show how the climate in states now will feel like states further south (& a little west) in mid-century, and much further late this century. Averaged across all 15 states, in the high emissions case, it's like moving 330 miles SSW for 2040-69 and 660 miles SSW for 2070-99.
For example, by the end of the century, New Hampshire would feel like the Piedmont today in North Carolina and Virginia, unless we cut carbon emissions deeply. Rhode Island's climate would be like Savannah's. Indiana's climate would resemble today's Virginia in winter and Oklahoma in summer. Minnesota's summer climate would resemble the Kansas climate of today. By 2100, absent steep carbon emission cuts, western Pennsylvania's climate would feel like Alabama's today.
See www.climatechoices.org/ne/impacts_ne/climates.html for maps of how climate would change for 9 Northeast states. Similarly, see www.ucsusa.org/greatlakes/glimpactmigrating.html for maps of how climate would change for 9 Great Lakes states.
