From the wind advisory text at weather.com: A TIGHTENING PRESSURE GRADIENT IS BRINGING BLUSTERY WINDS IN EXCESS OF 35 MPH TO PARTS OF CENTRAL ILLINOIS TODAY...AND GUSTS UP TO 50 MPH. WINDS ARE EXPECTED TO REMAIN GUSTY THROUGHOUT THE DAY...EVENTUALLY FALLING BELOW WIND ADVISORY CRITERIA THIS EVENING.
A WIND ADVISORY MEANS THAT SUSTAINED WINDS OF 30 MPH ARE EXPECTED...WITH GUSTS TO 45 MPH. WINDS THIS STRONG CAN MAKE DRIVING DIFFICULT...ESPECIALLY FOR HIGH PROFILE VEHICLES. USE EXTRA CAUTION.
Aside from making me wonder why forecasters used so many ellipses (these are not omissions), and also what a 'high profile vehicle' is, which then made me flash on that gigantic red white and blue bus we saw in Austin last year, the one with police escorts and a motorcade and which claimed it was carrying the Declaration of Independence, this advisory made me wonder vaguely what a 'tightening pressure gradient' is, and more interestingly, what all this means for those of us who don't drive high profile vehicles. So when Tillie asked to go in the backyard to play, I found out.
Leaves were swirling over from my neighbor's back yard at a height way above my head, and Tillie, a little freaked, stood very still in the center of our yard looking at me. Slowly the wind lifted her ears up, up. Kind of like the legendary Marilyn Monroe dress shot. I called her inside, and she didn't protest one bit.
