Cold June....

So far June has not only been wet but cold as well. Truckee is running 6 degrees below average for the month. A warm up is in store today and again during the weekend, will we finally break 80 for the first time this month? We have only broken 70 2 days so far & avg. high is around 76 this week. Reno is only a 100th of an inch off the second wettest June since 1870. I will be doing a more detailed recount of the month & first half of the year at the end of June. One thing I will talk about is the temps being below avg. 5 of the last 6 months. The change in May & June as far as moisture may be the first signs of the disappearance of La Nina & the now mild El Nino that may be showing.

As far as this week there is a storm splitting off the Pac NW coast today. The southern half of that storm will slide down the coast & come in South of us across Central CA tomorrow & Thursday. We should just see some clouds & a slight chance of thunderstorms for a couple days with slightly cooler temps. Looks like things dry out & warm up for the weekend.

A ridge may finally try to build over us for the first & second week of July. This could push temps well into the 80's finally just in time for the 4th of July. Lots of people are wondering about the remainder of the summer. There is no crystal ball but looking at the pattern developing over the Pacific it suggests that the periods of cooler & showery weather could continue to show up off & on throughout the summer. It won't get really interesting until we see if the pattern holds into October so we can finally get a good early season of snow. BA

Haven't we always had weird Junes? June of 2007 was at least 10 degrees hotter than average. I think this is the first time we have gotten a cold June in years. There is only one thing that I disagree with. It won't get warmer than this. I checked the weather for where I live, inland of San Francisco. It reached the high 80's here. Today is going to be the hottest day all around CA.

Since you asked I did a little research. Truckee was 2.2 degrees below avg. in June 08 & 0.1 above avg. in June 07. Over the past 5 years June has averaged .92 below avg. Over the past 10 Junes .7 below avg. It was split even 5 above avg. & 5 below avg., but the below avg. were much colder than the above avg. Warmest June I can find in the past 10 years is 2006 at 1.4 above avg. Coldest was 2005 at 3.9 below avg., but it looks like we will break that this year.

I agree yesterday may have been the hottest of the next week with the storm off the coast bringing cooler air. I do think we have some heat possibly coming for the beginning of July though.
