Good Sunday, folks. It’s another typical late July day in the bluegrass state, but stormy changes are a brewin’ for the week ahead. This is the week we make the transition from July to August and those storms will begin to knock the temps back down, with a bigger blast of cool air possible in the first full week of the month.

Temps today are back into the middle and upper 80s as we hang on to a mix of sun and clouds. A shower or thunderstorm will go up during the afternoon and evening hours, but this looks fairly scattered…

A system is dropping in from the northwest later Monday into Tuesday and will bring a much bigger increase in showers and storms, especially Tuesday…

Temps will come back down during this time and may not get out of the upper 70s for some on Tuesday. The trough digging in splits with one piece slowly working into the south. That may keep scattered showers and storms in the forecast through the week, with a possible uptick by the end of the week and next weekend.

That’s when a deeper trough looks to dig into much of the eastern half of the country. This has been pretty well advertised for a while and fits the overall pattern across the Northern Hemisphere. The Ensembles show what I’m talking about…

GFS Ensembles

Canadian Ensembles

European Ensembles

That shows the developing -EPO very well with the trough developing to the east of Hawaii and ridging over top it into Alaska. Here’s a different way of looking at it…

For those who have been reading me for years, you know a -EPO is usually a good indicator for a trough to develop across the eastern part of the country.

Have a great day and take care.
