September 5, 2008

Someone asked the other day (on another of my weather blogs) whether we’re moving into an early fall. Perhaps wishful thinking, but there are signs this may take place.

While it’s unlikely we’re completely through with hot and humid weather, the upper level pattern does favor several cold frontal passages in the period from September 8^th through 15^th.  The jet stream has dipped about 500 miles further south than usual for early September, which is the primary driver for this scenario.

Cooler air in the wake of each front along with precipitation potential should keep us with near normal daytime highs and somewhat cool overnight lows.  Beyond the 15^th…we’ll just have to see.

I’m optimistic that these factors and the overall North American weather picture point to only a low chance of a major heat wave this month (like we saw in September of 2000).

Take Care,
