Even before the heat wave struck, I was looking forward to today (Wednesday) because the computer guidance indicated a pattern shift by now. Sure enough, a cool front moved through last night causing the pattern shift and northerly winds. The north wind today has dropped dewpoint temperatures from near 70 degrees into the upper 50s in about 12 hours, which is very significant in terms of sensible weather. It feels far more comfortable today mainly due to the lack of humidity compared to the past several days. Over the years I have realized that dewpoints in the 50s don't last long this time of year. Typically about 24 hours or so, so enjoy it and take advantage of the lower humidity while it lasts. The humidity will rise a bit over the next few days, but it won't be as oppressive as the past several days, and as a matter of fact, the long range computer guidance indicates a significant cooling trend possible early next week. After this past weekend, next Tuesday might feel downright cold with highs in the upper 70s! Now, we wait and see if this materializes (and I cross my fingers hoping so).
