As low-level winds strengthen, moisture will pull in from the south, increasing instability in this system
and producing possible severe thunderstorms across most of the central United States. These storms will be associated with heavy downpours and may produce flash flooding over Missouri and Arkansas. At the same time, deep moisture in the South and Southeast will continue to contribute to scattered showers across the region.
To the north, high pressure positioned over the Ohio Valley will bring sunny and pleasant conditions across the region, Great Lakes and
central Appalachians. Meanwhile, an area of low pressure spinning over southeastern Canada will bring unsettled conditions to the Northeast during the day. However, high pressure will move eastward from the Midwest, producing clearer skies for the evening hours.
To the west, high pressure located over the western U.S. will continue to bring mostly sunny skies and dry conditions. However, monsoon moisture will kick up scattered showers over parts of southern Arizona and New Mexico. In addition, a trough over the West Coast will bring weak onshore flow, producing morning clouds and fog along the coast.
Temperatures in the Lower 48 states Thursday ranged from a morning low of 32 degrees at Truckee-Tahoe, Calif.,
to a high of 104 degrees at Dunn Helistop, Houston, Texas.
