The Start of Summer

If you’ve seen the forecast, you’re probably thinking that summer starts on Monday (or has already started). As we’ve said before, summer starts on the Fourth of July in the Inland Northwest. Yes, we will see some 90s for the first few days of this week as high pressure moves in from the Pacific. 


But most of the time, these hot spells that move in from the Pacific are short-lived, and this will be one of those.  By the evening of the 3rd, the high pressure is well east of us, with cooler air moving in from the west.

This will cool us back down into the 80s starting Thursday and continuing through the weekend.  

But then, we’ll see the true start of summer.  Our old friend the 4-corners high will develop around the 8th.  See the Big H in the desert southwest? That is the indication that we usually look for to start the hot summer days.  More 90s than 80s.


How about rainfall?  The first chance of rain will be around the 2nd or 3rd of July.  But the odds are very low.  Most likely this will amount to thunderstorms developing over northeast Oregon and move across southeast Washington, staying south of Spokane.  But there is always a chance that the storms could move a little farther north.


There is also a small chance of showers on the Fourth, as well as days after.   But the chances will be very small, less than 10%.


It will also be a little breezy again in the middle of this week, Wednesday through Friday.  Probably too much wind for dew formation on Thursday morning, and possibly Friday morning as well.

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...
