Weekend Weather Blog: May in Review

TWIN FALLS, Idaho (KMVT/KSVT) — May brought a lot of good news to southern Idaho when it comes to drought.

The image above shows how much we have improved since late April, with areas along the Snake River going from severe drought (dark orange) to moderate drought (light orange). Some areas of the region are still experiencing extreme drought, namely eastern Blaine and southern Twin Falls counties.

Nevertheless, it is safe to say that we have improved. The three climate observation stations in the observation area recorded above-average rainfall for the month of May. Twin Falls saw 1.7″ of rain, 0.24″ above the normal 1.46″. Burley saw 2.24″ of rain, 0.55″ above the normal 1.69″. Jerome saw 0.62″ of rain, 0.3″ above the normal 0.32″.

All of this precipitation has been great news over the past two months, and this trend is expected to continue over the next few days as an atmospheric river will make its way through the area on Sunday.

While precipitation was slightly above average, temperatures were slightly below average, allowing May to continue the cooler trend we have seen in 4 of the last 5 months.

At Twin Falls, the average high for May 2022 was 64°F. This as 4.7° below the normal of 68.7°F. Jerome saw an average high of 65.1°F, 4.4° below the normal of 69.5°F. Burley saw an average high of 63.4°F, 5.7° below the normal 69.1°F.

There’s no doubt that last spring was almost the opposite of last year’s spring, and that’s a welcome sign for many people. Next week’s weekend weather blog will discuss the behavior of the region throughout the period from March to May, also known as the “weather spring”.

For now, let’s keep hoping for more humidity for the rest of the summer.
