.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.
