After days and days of high-precipitation thunderstorms with embedded tornadoes and large hail, Oklahoma is finally getting a bit of a break. Just how wet was it there?
The Oklahoma Mesonet recently published rainfall totals for the past two weeks. Here's what it looked like:
Huge rainfall totals across the state. Over 12 inches in some locations in only 2 weeks. The annual percentage of normal rainfall has spiked through the roof. So far through the roof, in fact, that it's maxing out the colorbar on the Oklahoma Climate Survey plot, with most places greater than 180% of their total rainfall.
outlook from the Climate Prediction Center has drought conditions in Oklahoma and Texas "improving" over the next month...
Eastern Washington and Oregon have also been running a bit low on their precipitation and are in "drought" conditions as well. A warmer-than-average winter has allowed the western side of the Cascades to see about normal precipitation, but without much snowfall accumulating in the mountains. This is bad news for the eastern sides of the states, where they don't see as much precipitation, but rely on meltout from the snowpack to supply them with water for agriculture.
Here's a plot showing the snow water equivalent normals and what we've had this year at Stampede Pass, which is in the Cascades southeast of Seattle.
map of percentage of average snowpack as of last week, we can see pretty much everyone is basically melted out (or at least below 25% of where they should be).
