Gary McManus, Oklahoma Climatological Survey:
More than 3 inches of rain has fallen across east central Oklahoma, including
3.71 inches at Okmulgee. El Reno picked up another 2.85 inches to the west on I-40. Even southern Texas County got into the act with more than an inch of rain.
That gives them 3 inches in the last 7 days. Coincidentally, this is the rainfall we have to work with on this week’s U.S. Drought Monitor map. Looks like there will be some good improvements.
In those 7 days, widespread amounts of 3-5 inches fell across the NW and another
4-6 inches from central through east central Oklahoma, up into the northeastern corner. Still not quite so much across southern Oklahoma, but as that front sags farther to the south, perhaps they’ll get a bit more action down that way. All this rain has prompted a large flash flood watch over most of Oklahoma, and already there are flash flood warnings for east central Oklahoma.
The soils are quite saturated across most of Oklahoma, as evidenced by the 30- day rainfall map. Some massive totals on the map, even though some rainfall has dropped off from earlier in July.
All this rain brings the statewide average total for August up to 2.48 inches.
That’s already close to the normal total for all of August (2.75 inches), and August 2013 becomes the wettest such month since August 2009′s 3.85 inches.
The summer totals thus far were not helped much by June, even though it was fairly wet the first half of that month. Nevertheless, the statewide average for summer thus far (June 1-August 18) stands at 11.36 inches, which is 3.23 inches above normal for that period.
The kicker to this, of course, is that rain is still falling.
The longer we go into August with these rainy conditions, the chance for bigtime summer heat to return becomes less and less. Oh, it can still get hot, and with all this moisture, that would come with bigtime heat indices. But the chances of any type of extended heat wave goes down the further we get into the month and closer to September.
