.DISCUSSION...

Issued at 226 AM EDT Sat Jun 6 2026



In the upper levels, a ridge is centered over the Southeast U.S. At 

the surface, high pressure is over the Southeast. By this afternoon, 

a trough in the upper levels and a low pressure system near the 

surface will move into the Northeast bringing a boundary across the 

Ohio Valley. Dry weather will continue today. Temperatures and dew 

points will be on the rise today and Sunday as southwesterly flow 

continues. By Sunday, the aforementioned boundary remains well to 

our north. An upper level low gets somewhat stuck near KS/MO as a 

blocking ridge extends from the Southeast U.S. to Ontario, Canada. 

The remnants of this upper low will make it into the Ohio Valley 

Tues/Wed. 



Rain chances start to increase Sunday afternoon but remain low. 

Then, scattered showers and storms are likely every day next week. 

This activity will be hit and miss and mainly during the peak 

heating hours of the afternoon and evening. It looks like Monday, 

Tuesday and Wednesday may have the best coverage as the ridge drifts 

eastward. Overall, the pattern looks weak for forcing but 

instability will be high with increasing moisture (PWAT values near 

2 inches) and a high sun angle this time of year.
