Today brings much of the same of what we’ve seen as we have the same weather pattern set up with high pressure out in the Pacific and a low pressure system just off shore starting to become closed-off from the jetstream. The low will but cut-off for only a short period before opening back up and pulling a trough currently located in the Gulf of Alaska off shore. This will usher in a much cooler air mass as a blast of arctic air will make its way to our region. We’ll start to feel the cooler temperatures starting Sunday but even more so to start next week.
There is a catch though. Hurricane Leslie in the Atlantic is forecast to continue moving north which could modify the jetstream; if this happens a ridge could push into our region keeping temperatures from cooling as much as currently forecast. Weather models are struggling with this system and for now I have moderated the temperatures to somewhere in the middle. However, as we approach next week we could in fact see temperatures cool quite a bit more, or be a few degrees warmer. I currently do not have strong confidence in the temperatures to start next week, however I am confident that they will be much cooler than this week; the question is how much cooler?
We had a few showers in east Klamath and Lake counties early this morning that developed from the monsoon moisture that I had mentioned would be moving into our region. It arrived too early in the day and had little instability to work with so were very short lived storms. This afternoon we continue to lack the instability to keep thunderstorms in the forecast.
Fun fact: Hurricane Michael is the first category 3 hurricane this season!
