Cooler temperatures here to stay?

Ah yes, we can finally take a breath fresh (and cooler) air! Since Memorial Day, high temperatures have ran above the seasonal average in excess of about 70% of the time. We've had 8 days that reached over 100 degrees, 24 days in the 90's, and 9 days at 88-89. Normal high/low temperature right now […]

Refreshing Pattern Change Underway!

Yes, you saw the top image correctly: July 2021 was the hottest on record (followed by the hottest June on record across the U.S.). Finally we get to have a solid week of what a typical summer across the area should look like, compliments of a weak low pressure system that will pass through the […]

Cooler temperatures, but...

A cool down is still expected, but won't occur until Sunday or may possibly hold off until Monday. This is because high pressure over our region is strong and delaying the storm system that will bring cooler temperatures (system is currently in the Gulf of Alaska and slowly trekking south because it's being impeded by […]

Heatwave update

Because of high pressure building into the region, winds have shifted and are blowing smoke into our area from the fires to the east. This is causing areas of smoke and hazy skies with an orange tint to the sun. Haze/smoke may have an impact on forecast high temperatures and could cause such to be […]

Refreshing change to cooler weather and chances of showers?

Today's been hazy with smoke filled skies across the area. Satellite imagery clearly shows the smoke being drawn north into the state from the fires in Northern California. I don't know of anyone who's enjoying the heat and humidity (and I'm sure you don't either). For quite some time now, our region has been on […]

A few more days of heat, then cooler temperatures with shower chances?

With the exception of a two to three days here and there, high temperatures have been running above the seasonal average since May 28. I don't need to mention our few days of 80+ degree high temps in April and the near 110 degree heat in June. Hasn't it also been more humid this summer? […]

Monsoon moisture + thunderstorms. Heatwave ending, rain?

I'll talk about relatively cooler temperatures and possible rain here in a bit. But first, let's discuss thunderstorm possibilities today (Friday). We're on the western periphery of strong high pressure that's just to our east. Since the circulation around high pressure is clockwise, this is drawing up warmer air and monsoon moisture from the south […]
