Isaac Hangs Around To Start The Week

Good Monday and happy Labor Day everyone. The remnants of Hurricane Isaac brought soaking rains to central and eastern Kentucky Sunday. Many areas picked up 1″-2″ on the storm isn’t done with us yet. Tropical showers and thunderstorms will flare back up again today as the core of the storm works across the state. This kicks off a very busy week of weather.

Before we get into the future, let’s talk briefly about the summer that is now history. Meteorological summer runs from June through August and the numbers for Lexington look like this:

Average temp: 75.6  (Exactly one degree above normal)

Rainfall: 11.77″ ( That’s 0.57″ below normal)

History will look back at those numbers and think the summer was fairly typical. Yet, we know it was far from normal. Some of the hottest temps ever recorded were balanced out by below normal temps for June and August. Record setting dry weather in June was erased by a record setting wet July.

You would never think it, but the summer of 2012 was actually cooler than 2011 and 2010. Go figure!

Let’s talk about the first full week of meteorological fall.

Today will be another very tropical day with rounds of showers and thunderstorms going up as Isaac works overhead. Torrential downpours are likely. This tropical moisture hangs tough into Tuesday with more afternoon and evening showers and storms.

A cold front swings our way by Wednesday with another shot of showers and storms.

The weekend is getting my attention because it is likely to feature a big cut off low pressure across the Ohio Valley. This setup shows up very well on the European Model:

We could see an extended period of showers and thunderstorms from Friday through Sunday as much cooler air moves into town.

I leave you with the regional radar to track today’s stuff:

Enjoy your Monday and take care.
