The Ohio Valley finally enjoyed a widespread rain event and while not everyone got soaked, the official reporting station at the Northern Kentucky Airport recorded .44 inch of rainfall…the first measured rainfall there since September 30th when we picked up .01” at CVG. Twelve days without measurable rainfall is pretty impressive and normally it might lead to dry ground and plant stress, but after a September with more than 7 inches of rainfall our soils are doing just fine and the dry weather allowed us to get back to needed late-season activities such as harvesting, lawn mowing and shutting down pools and putting away patio furniture as we prepare for the winter ahead.
A cold front (leading edge of colder air) crossed the Cincinnati area around midnight Thursday night followed by clearing skies, a fresh westerly wind and cooler air. Even as the storm departed, a much large storm in the upper atmosphere has become established over eastern Canada and it will impact our weather through late next week. As an example, strong winds blowing around the Canadian vortex are creating gusty winds across the Ohio Valley and after gusts to near 30 mph on Friday we’ll have steady westerly winds through Saturday with speeds of 10 to 25 mph and some gusts near 30 mph by Saturday afternoon. Other than that we can expect plenty of sunshine and highs in the low 60s on Saturday.
The winds will continue on Sunday, but from a different direction…the southwest…and they’ll push warmer air back into the region for one day as highs climb into the 70s. There may be a late-day shower on Sunday with yet another cold front coming our way, and the shower threat will continue into Monday morning.
After that, a larger storm, moving around the south side of that big Canadian system I referenced moments ago, will develop in the Midwest on Tuesday with widespread rainfall, gusty winds and a push of the coldest air so far this autumn as we head into Wednesday and Thursday of next week…and we may have a killing freeze over much of the Midwest, including the Ohio Valley, by next Thursday morning.
I hope you enjoyed the string of warm (70s to low 80s) and dry days with light winds because that kind of weather is gone for 2011, though we’ll certainly have dry and mild weather, but not both at the same time lasting for five days or more. The polar jet stream is expected to shift further south in the next two weeks and that prevents the nice weather from hanging around for too long. Aside from the chilly start and some gusty winds, the weekend will be quite nice, so enjoy it!
