Weather Eye: Month on track to be one of warmest Julys on record

There was a strong enough push of ocean air Monday morning to help develop some low cloudiness to start the day. However, it quickly burned off and we enjoyed sunny skies. One could see some advancing high clouds to our south. The marine air kept our highs in the mid-80s.

With 90-degree highs over the weekend, we have now logged in 12 days this year with highs at 90 degrees or above. The average over the past five years or so is between 15 and 20 days. The average mean temperature for the month so far as of Monday in Vancouver was 7 degrees above normal. Our average high temperature for the month is 90 degrees. This month is on track to be one of the warmest Julys in the record book.

Today’s heat advisory is an indication that hot weather is with us and looking at the days coming up through the weekend show highs close and above 90 degrees each day. Some ocean air may filter in at times and keep some locations in the mid- to upper 80s but hotter air is probable later in the week through the weekend. We could add another five days or so of 90 or above weather, increasing our 90-degree tally.

This warm dry spell seems relentless, doesn’t it? It is great for the garden and outdoor sun-loving enthusiasts. It is not good for fire concerns and a fire watch is out today through Wednesday. Those clouds to our south Monday were a precursor of an increasing southerly flow from a weather system off the California coast.

That low will advance northward and bring warm, unstable and humid air to our region. Be on the lookout for late nocturnal thunderstorms tonight and daytime storms Wednesday, mainly along the mountains.

I’m expecting little if any rain with thunderstorms that do develop as moisture is limited. This would be a dry lightning event. Not good for wildfires. After that low moves out of the region, high pressure to our east will move westward and keep hot days and warm nights over us.

I cool off thinking about July 2011 where we didn’t even reach 90 degrees and several days were only in the 60s and we had over an inch of rain that month. Ah, memories. Take good care.
