Thursday Showers

Our dry weekend cool front has moved through giving us our expected windy Sunday. Monday will drop back into the 70s but that doesn’t last long as high pressure will bring us right back into the 80s for Tuesday and Wednesday. This is ahead of the next Pacific weather system due arrive on Thursday. Tuesday and Wednesday morning should have light winds and dew points in the 40s so expect a light to moderate dew.

As we talked about in the previous blog, this next weather system will go right over us, instead of moving by to our north like this weekend system did. And the difference in track will mean a difference in weather. Instead of just wind like we got on Sunday, the system on Thursday will bring us the threat of rain showers. The probability of showers has been increasing, now above 50%.


You can see in the graphic above that there actually is a small chance of rain on Wednesday.  This would mainly be from sprinkles ahead of the front and shouldn’t amount to much if any rain.  But a few of the computer forecasts do show enough rain to wet the ground from these showers.  So only a 10% chance of any rain on Wednesday, and even less of a chance that we’d see measurable rain. That said, if you have baled hay in the field, it may be a consideration for you. 

The rain amounts on Thursday could be around a tenth of an inch, with the best chance of rain near the BC border.  Here’s the National Blend of Models forecast of rainfall amounts.  It’s rather pessimistic, especially south and west of Spokane.



The European model has some heavier pockets of rain, as well as a bit more rain in the Basin. 


The GFS model is in some ways similar to the European model. 


Winds on Wednesday and Thursday will be breezy.  This will eliminate any chances for dew on Thursday morning.



This storm moves by quickly.  After a high only around 70F on Thursday, temperatures will warm to around 80F by Saturday.

You can see a couple of other items of note from the images above. First, we could see some more showers next Sunday and Monday. The details on this are pretty vague at this point. Also, things could be breezy during this period as well as the following week. This would be good for drying hay but could affect dew formation.

Very Snowy and Cold Next Week

Image
As we discussed in our previous blog, our mild winter weather is coming to an end.  We'll see some light snow tonight (Friday night), but then it should be snowing most of the day on Saturday, with snow showers continuing Saturday night and into Sunday morning.   The European model isn't too excited about the snowfall amounts with this system for the Spokane area (0.7"), but gives a healthy 3-5" to the northern valleys.  It has been very consistent with this forecast over the past couple of days. Meanwhile the GFS is much more excited about this storm, bringing 6" to Spokane and Sandpoint.  The difference is that the GFS lingers the storm over our area much longer than the European model.   There are lots of other models that give us snowfall amounts somewhere between the GFS and ECMWF forecasts above.  With temperatures right around freezing, this snow will be on the heavier wetter side.  Snow-liquid ratio (SLR) will be around 10:1, which means if you get 0.25&q

Wetter Weather Ahead

Image
In our last blog, we talked how broad low pressure was forecast to develop over the western US.  The details on this are starting to take shape.  I'll probably provide an update on this during the middle of the week, but here's where things stand now. First, we'll have a few dry and warmer days after our cold front on Saturday night.  High pressure will build into the area Monday through Wednesday.  Temperatures will be in the mid to upper 60s on Tuesday and Wednesday, with a little cooling on Thursday. But it won't last.  The low pressure in the above graph that is off the California coast will merge with the small low off the west coast of Canada.  This will create a broad area of low pressure over the western US by the end of the week. This weather pattern will bring us a cool and wet Thursday night and Friday.  The rain could reach our area by Thursday afternoon, but the best odds are for Thursday night, with showers on Friday.   That said, if the timing slows down,

Looking Ahead to Spring and Summer

Image
With the snow having melted and the road weight limit signs going up, our thoughts are naturally turning to Spring.  Will the mild temperatures and rain continue?  First, let's look at where we are on moisture. In the Northwest, things overall are on the drier side, with pockets of above normal precipitation. Zooming in a bit, we can see that the Columbia Basin overall has had above-normal precipitation, while much of the rest of the state has had near- or below- normal precipitation.  This makes sense.  We have had very little wind this winter (only one windy storm I can think of).  So the Cascade rain shadow hasn't been a factor this year. Looking even closer at a few locations, we see precipitation is very close to normal for mid-February.  In fact, it's rare that it is so close to normal (I know, that sounds strange).  Here's the Spokane Airport trace since October 1st.  The green line is the actual accumulated precipitation for this winter, while the brown line is
