Windy Labor Day!

For weeks, we have been stuck in hot, humid and stagnate air! That has changed! In the above map, I have plotted the winds (colors), wind direction, and pressure. The reason it is colder is because we had a cold front push through, but the reason it is breezy is because of the pressure gradient between Tropical Depression Lee and the center of High Pressure NW of us. Click image to enlarge.

The green lines are lines of equal pressure. Like a topographic map, the closer the lines are together... the "steeper" the gradient is... and the windier it is.Can you see how close the lines are over Arkansas? The shades of blues also indicate the winds at 20-30 mph.

I'd venture to say that this is the most comfortable Labor Day we have had in a long time! Enjoy it!

I'm laboring on this Labor Day, but it is the greatest job on Earth... so no complaints. I'll see you at 5:00 and 6:00 from the weather deck!
