Monsoon Update

Things are getting hot and a little humid out there thanks to our southerly monsoonal flow. And they’re about to get a little wet. In the previous blog I mentioned a small stationary low off the Washington coast that was predicted to move across northwest Washington on Thursday. That is still the plan. And when it does, it will draw monsoon moisture into it, creating rain and thunderstorms, but mainly west of the Cascades. 

But on Thursday night and Friday morning there could be a second impulse that could bring showers and storms to northeast Washington. Here’s the predicted rainfall for this event from the European model:


You can see mostly light amounts of rainfall (less than 0.10”) for northeast Washington.  There’s an equal chance that we will see no rainfall or just sprinkles.

This will knock our temperatures back a bit from the near 100F on Thursday. But it looks like we’ll stay in the 90s through the end of the month.

We’ll also see some drier air, allowing our low temperatures to drop to around 50 over the weekend. We might get morning dew over the weekend, but the relative humidity should be high enough to do some early morning baling.

Theres a small chance of rain each day next week, but probably not enough to change any plans at this point. The best chance of rain will be on 22 or 23 July.

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...

When Can You Start Cutting?

The answer to this blog’s title isn’t an easy one, and it’s going to depend on what risk you’re willing to take. The overall set up is this. The large low pressure system will wobble around the Northwest and vicinity for the next few days. But even when the low is east of us, we’re not out of the woods. Rainfall over Montana or even BC can wrap around the low into our area, even as late as Tuesday. So if you want a sure-fire dry forecast, you’ll probably have to wait until Wednesday.  But some folks have a lot of hay to cut and can’t wait that long. So here’s some probabilities of rain and amounts to consider.  If you live up north near Colville or Newport, odds are pretty high that you’ll see more rain, especially on Sunday night and Monday.  And it could be as much as a third of an inch. If you’re closer to the Deer Park area, the story is similar, but the amounts and probabilities are a bit lower.  Maybe a quarter inch? And if you’re down by Spokane, well then the...

Rain Returns - Update

Image
The computers are remaining true to their word.  Our long dry spell will be ending on Wednesday, with the potential for a nice rainfall.  More showery chances of rain then continue through the weekend. First I’ll show you the average of all of the computer forecast rainfall for Wednesday. 0.1” around Spokane, with 0.25” north and east of the metro . Here’s a few of the individual computer forecasts.  The US GFS model gives around a half inch to parts of northeast Washington. . The UK is similar to the blend of models. The European AI forecast is a bit more generous with the rainfall.  And lastly the European model predicts over an inch for parts of Ferry and Stevens counties.  There could be some thunderstorms on Wednesday as well.  So everyone should get a little rain, but some folks could get more. Tuesday: Sunny and very warm.  Highs in the 80s. Wednesday: showers and thunderstorms.  Highs in the mid to upper 60s. Could be gusty in the afternoo...
