Fall weather on the way

The rainy pattern of the past 2 weeks has finally shifted east today. Weak high pressure takes over this weekend before another cold front moves through Monday. However, this front will be dry. Thus, the MWN forecast reflects dry and warm weather this weekend, followed by cooler and much less humid weather behind the front for much of next week. In fact, dewpoint temperatures - a measure of humidity in the air - will be their lowest since spring. These low dewpoints will allow overnight temperatures to drop as well, with some locations in outlying areas near 50 by Tuesday and Wednesday mornings! We'll be watching for another front late in the week that could bring our next chance of rain.

Interesting fact of the day: Though there was much more accumulating rain the week before last than this past week (at least in the metro area), the manual rain gauge co-located with the WXLIVE! rain gauge recorded 13 straight days of measurable precipitation. That string will come to an end today, and it's about time! To learn more about the CoCoRaHS program, a network of volunteer precipitation observers, click here.

In the tropics, Tropical Depression #8 formed in the Atlantic a couple of days ago, but as of 3pm has deterioriated into an open wave, meaning it no longer has a closed circulation and cannot be classified as a depression.
