Northeast - Showers and thunderstorms are likely from central and western New England and Upstate New York to the Virginias both Thursday and Friday. Only eastern New England seems to escape the shower and thunderstorm threat both days. Severe thunderstorms capable of delivering damaging wind gusts and hail are possible in West Virginia and western Virginia Thursday afternoon and evening. High temperatures Thursday and Friday reach the 70s to lower 80s in Upstate New York and New England. Warmer highs mostly in the 80s occur from Pennsylvania and New Jersey southward to the Virginias. A few neighborhoods could reach the very low 90s before any thunderstorms develop in West Virginia and Virginia.

Midwest - Hot temperatures and strong to severe thunderstorms dominate the region over the next few days. A large high pressure ridge centers itself in the Mississippi Valley through the weekend. High temperatures in the middle 90s to lower 100s are likely in Nebraska, Kansas, Missouri, southern Illinois, southern Indiana and western Kentucky into the weekend. High humidity combined with the hot temperatures gives heat indices of 98 to 110 degrees each afternoon. Not much relief comes at night with overnight lows hold in the middle and sometimes upper 70s in the middle Mississippi Valley, lower Ohio Valley and eastern Nebraska/Kansas. Scattered thunderstorms, some severe, ring the hot ridge occurring from the northern Plains to the Great Lakes, Ohio Valley and eastern Kentucky through the weekend. Thursday's severe threat stretches from eastern Minnesota and northern Iowa southeast to Ohio and eastern Kentucky. Damaging wind gusts and hail are the primary severe threats. In the stormy areas high temperatures should be mostly in the upper 70s and 80s.

South - The big heat dome centers itself in the Mississippi Valley through the weekend keeping the heat and humidity high. High temperatures reach the 90s to lower 100s over the entire region with upper 90s and lower 100s in the lower Mississippi Valley, Oklahoma and Texas through Saturday. Combining the heat and the humidity produces heat indices of 95 to 110 degrees each afternoon. Overnight lows hang in the 70s with some areas in the middle and upper 70s, so there will not be much cooling at night. The best chance of having some cooling afternoon and evening thunderstorms is over the Carolinas, northern Georgia, northern Alabama and eastern Tennessee. A back door cold front sinks southward through the Carolinas and into Georgia over the weekend. Temperatures should drop 5 to 15 degrees behind the front. There are indications that the front could make it all the way to the Mississippi River early next week.

West - Monsoonal thunderstorms will be scattered about the Rocky Mountain states again Thursday and Thursday evening. An usually strong upper low along the California coast continues to pump moisture, including some from Tropical Storm Lowell, into the Rockies. Heavy downpours, flash flooding and gusty winds are possible from any thunderstorm. Friday the upper low finally pushes into Arizona bringing drier conditions to Arizona and Utah. The heavy showers and thunderstorms should still be scattered from New Mexico to Montana Friday. High temperatures continue to be below average throughout the Rockies due to the clouds and storms Thursday. Afternoon readings range from the chilly 60s and 70s in Montana to the middle and upper 80s in northern Arizona and northern New Mexico. High temperatures reach the 70s and 80s in the Pacific Northwest and along the California coast. Warmer highs in the 80s and lower 90s are forecast in central and southeast California, southwest Arizona, southern Nevada and east of the Rockies from eastern Wyoming to eastern New Mexico.
