HEADLINERS:
Heat and air quality issues expand to cover parts of B.C., and most all of Alberta and Saskatchewan.
Heat shifts toward the Northern Rockies/Northern High Plains.
Thunderstorms with heavy rainfall are expected in the Four Corners region and from the western Gulf Coast into parts of the East.
The weather pattern remains active as we head through the final week of June. Severe thunderstorms and heavy rainfall will continue to impact parts of the Plains, Midwest, Ohio Valley, and Mid-Atlantic through the week, while dangerous heat remains locked in across portions of the South and expands eastward by early next week. Meanwhile, wildfire concerns are increasing across the Four Corners region, and a cooling trend is finally on the way for parts of the West this weekend. Residents in several regions should be prepared for rapidly changing weather conditions, including flash flooding, severe storms, and periods of dangerous heat.
