September ended on a dry note. In fact, as Sarah mentioned in her post, OKC has gone 17 straight days without any rain. Total OKC rain for September was .59″, which is 3.25″ below normal.
October will start off dry the first few days. I am seeing signs of a chance of thunderstorms next Sunday into Monday. Take a look at this:
A strong upper storm system will be moving through the western United States, toward the Plains. At the same time at the surface, moisture will be streaming north from the Gulf of Mexico. Dew point temperatures should climb into the 60s by Sunday. Thunderstorms could break out in the central and perhaps southern Plains Sunday into Monday. One thing that will likely happen is an increase in southerly winds starting Friday and continuing into the weekend. Gusts of over 30 mph will be possible.
The different computer models are not in agreement on how this will all work out. In fact, some models vary wildly from run to run. I have low storm chances in the forecast for Sunday and Monday. While much will change between now and then, I would not be surprised to see some severe storms in the Plains by late in the weekend. More on this tomorrow.
