Any Rain in our Future? - Update

The upcoming weather pattern change is still on track. Warm and dry weather will be replaced by a cooler and wetter pattern. How much rain will we get and how long will it last?  Unfortunately it doesn’t look like it will be really wet or long-lasting. These spring storms typically have more uncertainty than a strong winter storm. So it’s hard to be definitive. 

A few mountain sprinkles are possible Saturday with warm temperatures and breezy afternoon winds. A better chance of rain will be on Sunday, with the highest chance of showers on Monday. 

Here’s a few computer forecasts of the total rainfall through Wednesday morning. First, I’ll start with the National Blend of Models. Like the name implies, this is a blend of a number of computer forecasts. 



Then here’s the European model. It has more rain in the Basin, less over northeast Washington. 



The US model (the GFS) is similar. 




The model below is the AI (artificial intelligence) model for the Europeans. It’s experimental so I don’t have much confidence in it yet. 



The largest disagreement between the computers is where will the band of heaviest rain set up on Sunday. These UK model puts it north of Deer Park while the European model has it down by Lewiston. 

After these 3 days of rain, the storm moves out and we'll have a few dry days mid week before another threat of showers for the weekend. 


So overall, we’re probably only looking at about 1/4” of rain for most folks, although this will obviously vary.

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 ...

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...

Uncertain Fourth

Image
In the previous blog I mentioned that there was too much uncertainty in the computer forecasts to look very far into the future. Unfortunately that’s still the case.  I’ve shown the graph below on a previous occasion, but it can be a little confusing so I try not to mention it. So I’ll try to explain. There are three computer centers that produce multiple computer forecasts.  The US, the Canadian, and the European. All together they produce 100 computer forecasts. You can easily average them all together, but this can hide possible scenarios. So another way is to look for clusters of solutions. Below shows four possible scenarios for July 2nd. It doesn’t take a meteorologist to figure out that each one is different.  Some have the hot high pressure (orange color) over the Northwest.  This would bring hot and dry weather.  But the other two have the high pressure to our east.  This would mean a cooler forecast for us, along with a threat of showers. And each...
