Christmas brought a good soaking, as almost 6 inches of rain fell in the Tulsa area alone.
We could see even more rain because of the ocean-atmosphere system disruption known as El Niño.
"The main impacts from El Niño typically start later in December and then last through February, March," said State Climatologist Gary McManus. "So, possibly, the wettest part of this El Niño is still to come."
Snow has been in short supply so far, and that will likely continue.
"It does look like we will be warmer than normal and wetter than normal for much of this cool season," McManus said. "With the majority of the United States much above normal in temperature, there's just really no way for that Arctic air to seep down here."
El Niño events happen when surface temperatures in the Pacific Ocean are unusually warm near the equator. 2015 is the wettest year on record for Oklahoma as of mid-December. The previous record was set 58 years ago.
Most of Oklahoma's 44 reservoirs are at or over capacity, thanks to the record-setting year, and the water supply should be set for awhile.
"It's really when we start to warm up in the spring and then get into the summer that we'll start to worry about some of those reservoirs again," McManus said. "Now, eastern Oklahoma is just fine. In fact, most of those are at flood stage or above. For central and western Oklahoma, some of those are still a little bit below normal."
Right now, even the reservoirs that are low are at around three-fourths full. In May, the lowest reservoirs in Oklahoma were less than one-third full.
