9pm Sunday…
It’s a new workweek for me but for most of you it was a fantastic end to the weekend. Sunshine covered the entire Pacific Northwest this afternoon and we ended up right at normal here in Portland = 66 degrees.
If you’ve been outside the past couple of hours you know temps are cooling off quickly. With high pressure overhead, a dry airmass, and clear skies, temperatures will plummet tonight. Lows drop way down into the 40s with even a few upper 30s in the colder outlying parts of Portland. Hopefully you didn’t plant your warm weather veggies yet…it’s a bit too early. Not just because of another chilly night but we see quite a change in the pattern after Wednesday.
The good news is that we have 3 warmer days ahead. We should be somewhere between 70 and 80 degrees each of the next 3 afternoons. But then the cold showers return. Take a look at the ECMWF ensembles showing 24 hour precipitation amounts the next 15 days:
You can see the very good agreement among the ensemble members showing pretty solid .10 to .30″ 24 hour rain totals for at least an 8 day period beginning Thursday. This goes along with the 850mb ensemble chart
A nice warmup for 3 days, and then those pass-level temperatures (in the free atmosphere) plummet down to around freezing during that 8 day period. Of course with the strong May sunbreaks we’ll get very little snow down to 4,000′, but the point is snow returns to the higher elevations late this week and the valleys will feel more like early April again. Lots of showers, hail showers, and probably cold thundershowers here and there. Also note there is a tick upward about 12 days out. You see the decreasing rain totals on that previous chart as well. The GEFS (GFS ensembles) have more ridging near the end of the 16 day period too. You can see the upward trend in temps when average. Of course the blue line is the operational run and it appears to be much warmer than the mean (average) of the ensembles. Remember these charts show the temperature around 4,000′ or so. The GEFS surface temps look like this, showing the same 8-10 day cool spell ahead:
So buckle up, enjoy the 3 warm days ahead, put off all your indoor tasks and enjoy the sunshine!
One more bit of good news…ALL Willamette Basin reservoirs are full and it’s just the first of May. You can see it on the Army Corps of Engineers “teacup diagram” page.
There will be PLENTY of water for this summer, including irrigation (more of an issue typically east of Cascades) and water recreation.
Chief Meteorologist Mark Nelsen
We had a solid five minutes of pea-sized hail about thirty minutes ago and currently listening to thunder in St Helens.
Some heavy showers here this morning. Looking at this spring since it officially began on March 21, I’ve only had 10 days without a raindrop(out of 52). If this keeps going, it’ll be the spring with the least number of dry days, beating 1981. (20 days)

Well now this ain’t too friendly looking..
It is sure sign that the fleet will be arriving shortly.
I don’t like the looks of it! Anyway, I’ve got one more tomorrow to enjoy this currently pleasant weather.
Blue is your friend….
Well, at least for myself and Roland, there’s a white ‘N’ and not a blue ‘B’ over us.
Put up 2 additional panels to day giving us 800 Watts.
But…we have about a 10 watt loss in due to resistance in the line.
But still operating our air conditioning off of solar..is priceless..oh as is our fridge,freezer , and water cooler.
We got up to see 75? Eerg…
Got my tomatoes into larger pots today, but not into the ground. It’s still too cool there. I think i’ll wait for a couple of weeks .
Koin got rid of Kristen Van Dyke. Now she works for a station in Salt Lake City. Sad to see her go.
Never could stand her. Bring back Bruce. Peace.
Bruce is on with KATU now.
Crap! I planted this weekend. I spent both days replacing all my dandelions, amaranth, bittercress and curly dock with corn, tomatoes, peas, beans and strawberries. My lower back hates me today!
Too late now… 😦
Old man…better work on that back.
HAH!! I’m just fat and out of shape from the long Winter… Bring me a long string of nice weather so I can get back on the bike, will ya?! :-p
we have pumpkins…but there in suspended animation..i think..
We’ll take those 3 days ..3 days of solar is better than nothing!
36F here this morning
Warm and dry but not hot – very nice!
The Rose Festival low is building Rain for the next month!
Right on schedule!
A few more nice days ahead to pull weeds and kill slugs. Got my covers over the tomato beds warming the soil before we plant ’em…after the next cold shot.
