Rain for the End of September

September 2025 has provided us with a lot of sunshine and warm temperatures. In fact, with a week to go, Spokane is looking at the potential for its warmest September ever.  A lot could happen in that last week, so it’s not a guarantee.  But 2025 September is currently running almost 3 degrees warmer than the current record holder of 1938.  Remarkably, second place was set last September.  The trend of the last few decades is clearly for a warmer September.



But the computer models expect the month to end on a cooler and wetter note.  We’ll have one more day in the 80s tomorrow (Thursday). And then a dry, breezy cold front will drop our temperatures back into the 70s. The wind and warmth on Thursday could cause some wildfire concerns. 

A change in the weather pattern will occur next week.  The first front on  Sunday night and Monday will bring a low chance of showers.  Tuesday and Wednesday will have a high chance of rain.  And there’s continued chances of rain for the rest of next week.  Here’s the probability of rain for the next 10 days at Deer Park.


We’re not looking at any thunderstorms like we had on Sunday.  So rainfall amounts for the week should be around 0.25”, with more in the north and less in the south.  Here’s a computer estimate of the total rainfall through Thursday.

Showers and Storms this Week

Image
The last week of July is (on average) the hottest week of the summer.  We are looking at 90s Mon-Thu this week, so this may be following the pattern.  The longest day of the year is June 20th, with 16 hours of daylight in Spokane.  By the end of July, we've already lost just over an hour of that.  Not that the length of day is the only factor of hot weather, but it obviously has an effect.  The days noticeably get shorter in August, losing about 3 minutes of sunshine each day. We were talking in the last blog about the potential for showers and thunderstorms this week.  As usual, things are becoming a bit clearer on timing and coverage.   Afternoon and evening thunderstorms will increase over the next few days over eastern Oregon, slowly creeping north each day. By Tuesday, the southern Washington Cascades could see an isolated storm.  Wednesday will see the potential for afternoon thunderstorms over most Washington mountains. Here’s the European ...

The End is In Sight

Image
We're currently in the middle of a rather unusual heat wave at the end of summer.  And some records could still be reached.  For those who aren't a fan of the heat, there's good news:  an end to the heat wave is in sight. Here's the somewhat odd weather map.  There's a skinny but strong area of high pressure over the Western US that extends up into BC and the Alaskan Panhandle. A weak low off the Washington coast is sending waves of moisture into our area at times.  This caused all of the clouds last night along with a few showers and thunderstorms.   Meanwhile, the eastern US is still experiencing fall-like temperatures.  Low temperatures in the 40s dipped all the way south into North Carolina this morning.  State College, PA has already had 3 nights in the 30s. By Thursday of this week, the weather pattern won't have changed a whole lot.  Another surge of cool air invades the Great Lakes region, while high pressure continues to dominat...

Weather After the Rain

Image
It took some patience, but eventually the rain fell in most places. It doesn’t make up for our dry spell, but it sure helped.  Here’s how much rain fell from the weekend storm.  Here’s a different view of the rainfall over the weekend.  It’s actually pretty close to the forecast graphics I was showing you last week.   So what can we expect for the next 10 days?  Kind of a temperature roller coaster.  After a showery Monday, we’ll warm up quickly on Tuesday, back into the lower to mid 80s.  A mostly dry cool front on Wednesday will bring some mountain showers, breezy winds and cooler temperatures.  We’ll be back in the 70s for Thursday and Friday with more mountain showers over northeast Washington. High pressure from the west will build into our area for the weekend, quickly sending temperatures climbing into the 80s, with 90s by Monday of next week. Beyond this things get more iffy.  There isn’t any clear cut agreement among the compute...
