March Rainfall: A Small Fraction of Average

The rainfall numbers for March tell a story of an increasingly severe drought over Texoma. We share this problem with large portions of Texas and Oklahoma.

The maps below show March rainfall coming in at only a paltry fraction of the average, which should range from 2.70” at Ardmore to about 3” in Ada, and 3.40” in Sherman and Durant (discussion continues below map).
The long-range forecast for April suggests warmer and drier than average conditions will dominate. This is partially thanks to unseasonably strong high pressure aloft, which will tend to divert most of the storms to our north.

    Global warming beyond La Nina is showing its ugly head more and more.

    Rebecca, Thanks for your question. La Nina is indeed weakening, but that by itself doesn't guarantee an immediate shift to the pattern. Plus, a persistent pressure oscillation over the arctic and North Atlantic is tending to keep upper lows over the eastern U.S....which does not favor lots of rain for us. The "official" long-range outlook is a slightly greater chance of a drier than average summer than one with normal or above normal rainfall...but the bottom line: with the La Nina weakening, there is more uncertainty with this forecast than we had last year. So let's hope we get a wet's possible but the odds look to be slightly against it. Take Care, Steve

    I thought I read somewhere that the local drought is due mostly to La Nina and that this weather pattern would be going away soon, can you tell anymore about this?
