Hottest Day So Far, Even Hotter Tomorrow

video preview image

A ridge of high pressure will be strengthening and moving inland during the day today, this will act to warm inland areas to the warmest of the year so far, bring abundant sunshine to the region and return the marine layer to the coast. This evening clouds will be increasing at the coast as the high pressure moves inland we’ll see onshore flow return and that will bring the marine layer stratus overnight. Inland areas will continue to heat up, the temperatures to beat for the hottest of the year so far are as follows:

  • Medford: 91 degrees on May 10 & 11…Forecast: 93 degrees
  • Klamath Falls: 83 degrees on May 11…Forecast: 84 degrees
  • Mt. Shasta: Record breaking 88 degrees on May 11…Forecast: 89 degrees
  • Yreka: 90 degrees on May 12 & 13…Forecast: 94 degrees

Tomorrow high will be a degree or two warmer! A cut-off low will form off the central California coast tomorrow and Thursday; if it’s able to tap into monsoonal moisture it could bring Siskiyou county isolated late afternoon thunderstorms. The favored spots are south of our viewing area, but some could form south of Siskiyou county and make their way north into the county. I’m keeping a slight chance for thunderstorms, but more areas will most likely just see a few more afternoon clouds albeit still mostly sunny.

Next week a cold front will bring us cooler temperatures and perhaps even some rain! We just need to get through this hot week first. Thanks for logging on and be sure to follow me on Facebook for more weather updates and to share your weather photos!
