After a long dry spell, and over an inch below normal for rainfall, showers are helping those newly planted crops in the Brazos Valley.
What took so long?
It wasn't for lack of moisture that we didn't get the rain. With Southerly winds, Gulf moisture has been pumped into the Brazos Valley for days now. Dewpoints (a measure of how much water vapor is present in the air) have been in the upper 50s and lower 60s since last week.
What's been killing our rain chances is the high pressure area over the Southeast United States. That high wasn't so strong that it wouldn't allow clouds to form, but strong enough where the air particles couldn't rise high enough to cause rain to precipitate out of those clouds.
We've been on the fringe of that high pressure system, and while there's been plenty of activity just to the West of us, it couldn't make it to the Brazos Valley.
Two things happened with the high pressure system today. First, it weakened slightly. The center of the high wasn't as strong as it had been this last week. Second, the position of that high pressure system moved further to the East. It's now positioned over the Carolinas, whereas it had been sitting over Georgia and Alabama.
Of course why we're getting the rain isn't as important as that we're getting the rain, and chances look just as good for another round of rain tomorrow (Thursday), so you can keep your fingers crossed and know that if you didn't see any showers today, there's still hope for tomorrow!
