Cold Morning Chaos

The early morning showers dodged the Corvallis area, so dry weather was had throughout the last couple of days. Skies overnight had cleared out and temperatures plummeted a lot more than expected, which threw most forecasts out of whack by a good 5-8 degrees. Oops. Accuweather was the best of the bunch.

Sunday: High 64, Low 39.
Monday: High 66, Low 33.

Corvallis, Oregon to La Crosse, Wisconsin

Time to connect today’s two forecasts with a 1900+ mile road trip! It’ll take four days to get from Corvallis to La Crosse, will we encounter any surprises in the mountains?


Some overnight rain showers should fizzle out by the time we wake up to begin our trip heading north towards Portland. As high pressure builds in over the Pacific Northwest, skies should begin to clear out as we head eastward on I-84 then northward into Washington in I-82. Dry conditions will persist throughout the rest of the day as we end our first day in Spokane.


We’re going to spend a lot of time on I-90 from here on out. Like, the ENTIRE remainder of the road trip. Guess we don’t need that map anymore! What we will need are sunglasses since high pressure is parked over all of the Northern Rockies, making for dry and quiet conditions the entire way from Spokane through far northern ID and into Montana before finally ending the day in Billings.


High pressure continues to keep a firm hold over the Northern Plains, so another day full of dry weather and bright sunshine is in store. We might see some high clouds filter in as we push into SD due to an area of low pressure down over the Mid-MS River Valley, but no precip should affect our travels. We finish the day in the small central SD town of Murdo.


It’s a pretty straight shot eastward today as our road trip comes to an end. Our friendly neighborhood high pressure continues to grace us with it’s clear skies and dry weather, and should make for a pretty easy trip through southern MN into La Crosse.

Corvallis, Oregon

Today we head out west and check out what’s happening in Western Oregon! Hopefully some nicer weather than we’ve had around here last few days.

At 820pm PDT, the temperature at Corvallis, OR was 54 degrees under overcast skies. A cold front is dropping southward over the Northwestern US, from southern WY to far Northern CA. Some scattered shower activity is found throughout western OR and are generally pushing to the southeast as the front continues to push away from the region. Activity will trail off overnight as high pressure builds into the Pacific Northwest during the day tomorrow. This high pressure will keep the area dry into the start of the workweek. Overall a fairly nice couple of days coming up!

Sunday: Possible early morning shower, then decreasing clouds and dry. High 68, Low 46.
Monday: Clear and sunny. High 71, Low 40.

TWC: Sunday: Partly cloudy, an isolated morning shower. High 66, Low 46.

Some scattered shower activity is lingering in the region tonight, shifting towards the southeast. This activity will trail off overnight and a dry couple of days looks to be in store.

The weekend slips away

Corvallis was at the tail end of a weak system when we checked in on Friday. Snow was falling in the higher Cascades, but things were on the upswing in the home of Oregon State University. Temperatures didn’t fall off after midnight on Saturday morning, and it all looked pretty good, with a warmer than expected start on Saturday. It all fell apart, however, on Sunday, as a storm coming out of the Gulf of Alaska socked the Pacific Northwest. There was even a stray flurry for Corvallis, as on Sunday, temperatures started cooler than anticipated. Kind of a crummy end to what had started as a nice weekend. Accuweather enjoyed the day’s top spot.
Actuals: Saturday – High 48, Low 35
Sunday – .34 inches of precip (some snow) High 44, L:ow 32

Corvallis, Oregon

Good evening. Should we see what’s happening in Oregon?

At 1115PM, PT, Corvallis was reporting a temperature of 39 degrees. While Corvallis does not report sky cover, local sites were reporting mostly cloudy conditions.  A sharp trough, perpendicular to zonal flow, slices through southern Oregon and his producing a weak area of low pressure, which is generating enough moisture to insist upon winter weather advisories for the Cascades closer to Medford.
The trough is anomalous in its orientation, and will be snuffed out by the system’s attempt to equilibrate. Saturday looks to be in good shape, but a strengthening jet arcing over the Gulf of Alaska is carrying an Arctic wave along with it. Expect some chilly rain to move through, essentially washing out the end of the weekend.

I picked the water vapor today, because it best shows that rotation off shore of Oregon. It actually looks stronger here than it actually is.

Missing the memo

The day after Independence Day in Corvallis was supposed to cool down a bit thanks to increasing westerlies leading to more clouds. Not so much. Temperatures actually climbed a bit from the 4th of July, where it was 78 degrees, to 80 degrees on the day after. Not a single outlet had the temperature trends pegged down, which meant the warmest forecasts narrowly edged the rivals. Weatherbug and Accuweather collected a tie atop the leaderboard.
Actuals: Monday – High 78, Low 48
Tuesday – High 80, Low 50

Corvallis, Oregon to Bay City, Michigan

We have a lengthy road trip in our future, as we are scheduled to last 4 1/2 days, covering 2437 miles. This will put us on a pretty quick 67.7mph pace. Our full days will last 542 miles, leaving a little bit of change at the end. Let’s navigate our way through some mountains.

DAY ONE (Wednesday)
corvallisAs we discussed yesterday in relation to Corvallis, there is a nice little area of of high pressure over the Pacific Northwest. There will be heat in the valley, and likely nott a cloud in sight from western Oregon into Idaho. We will make it to Wendell, Idaho to finish the day off. It should be plenty warm there as well.

DAY TWO (Thursday)
There will be a little bit of shower activity in the northern part of the Front Range from Montana to Wyoming, but an organizing low in the High Plains will wrap moisture into itself and away from the northern Rockies. We will make it to Elk Mountain .Wyoming without a drop, and call it a night.

DAY THREE (Friday)
That low that mentioned on Thursday will be a bowling ball of concentrated energy, shooting through the Upper Midwest and dragging slightly cooler but mostly dryer air into the High Plains. Once again, we will enjoy dry conditions for the drive on Friday, as we head out of Wyoming and across the longest part of Nebraska, coming to rest in Lincoln.

DAY FOUR (Saturday)
The next wave will be moving into the Plains, thanks to predominant westerlies and the Rocky Mountains, overnight Friday into Monday. Southerly flow returning to the Plains will conflict with the southerlies behind the previous system, and in Lincoln, we may see a smattering of rain showers. The wet weather won’t be long lived, however,and we’ll be able to get through Iowa and Illinois unscathed, ending the day in Portage, Indiana on the shores of Lake Michigan.

DAY FIVE (Sunday)
As has been our fortune on this trek, expect more clear weather on Sunday as we make the final drive diagonally across the Lower Peninusla. It looks like the heat that we will see through much of the trip will even abate, leading to a pleasant end to the weekend in Bay City.

Bay City

Corvallis, Oregon

Time for a trip out west to a town that I kind of like forecasting for. Oregon is so diverse, and so exposed to the north Pacific. You really have to trust the guidance. It’s tough some times.

At 1135PM, PT, Corvallis was reporting a temperature of 57 degrees. They weren’t reporting a sky condition, but Salem, Eugene and even Newport on the coast were all reporting clear skies. There is a broad upper level trough angled towards the Pacific Northwest, but at this time, the surface reflection was all organized in southwestern Canada.
The jet will strengthen along the Columbia Gorge, feeding into the development of low pressure in Alberta and British Columbia through the day Monday, but it will actually draw moisture in from the Plains, meaning most rain and thunder would remain north of the border.  Corvallis will be dry each of the next two days, but the upper level westerlies may make things a bit cloudier than it has been tonight.
Tomorrow – Partly to mostly cloudy, High 78, Low 51
Tuesday – Mostly cloudy, High 76, Low 52

TWC: Tomorrow – Sunshine and some clouds. High 80, Low 51
Tuesday – Mostly sunny skies. High 78, Low 52

AW: Tomorrow – Partly sunny High 80, Low 50
Tuesday – Periods of clouds and sun High 77, Low 51

NWS: Tomororw – Sunny High 79, Low 51
Tuesday – Mostly sunny, High 76, Low 52

WB: Tomorrow – Mostly Sunny, High 78, Low 50
Tuesday – Partly cloudy, High 76, Low 52

WN: Tomorrow – Mostly Sunny High 79, Low 52
Tuesday – Partly Cloudy High 75, Low 52

FIO: Tomorrow – Partly cloudy starting in the afternoon. High 80, Low 50
Tuesday – Partly cloudy in the evening. High 76, Low 49

I suspect if this forecast goes awry it will be because of temperatures varying a little too little, thanks to their being more clouds than expected. Speaking of clouds, at the moment, there are hardly any in the Pacific Northwest. Take THAT, generalizations.


Corvallis still getting drenched

One could say that the weather Corvallis received the past couple of days was befitting a duck, but that might cause some disagreements in the home of the Oregon State Beavers. Their rivals, the Oregon Ducks are from Eugene. The weather was rather rainy, though, especially before sunrise and after sunset yesterday, when the two times combined for .85 inches of rain. The soggy weather helped keep temperatures down , which played a huge role in identifying the eventual forecast winners, which happened to be the National Weather Service. WeatherNation had their highest finish yet, coming in second.
Actuals: Monday – .01 inches of rain, High 42, Low 35
Tuesday – .85 inches of rain, High 50, Low 39

Corvallis, Oregon

We are off to western Oregon for this evening’s forecast. It’s a part of the world that has been getting pounded by a pipeline of moisture from the Pacific. How much more is in store for Corvallis?

At 335PM, PT, Corvallis was reporting a temperature of 35 degrees with overcast skies and fog. The thatch of thick fog continues to fill the valleys of the northern Oregon Cascades, but actual precipitation has evacuated the region. A surface low over northern California is continuing to press to the southeast, taking any rain and snow inland, but no scouring boundaries means the lower level moisture will remain for Corvallis.
Of course, it doesn’t help that there is an area of persistent low pressure over the Gulf of Alaska. A particular wave is moving into British Columbia, and the resultant westerly flow at the south end of the wave will reinforce moisture over western Oregon. This means fog and clouds tomorrow morning, with rain developing again in the afternoon as the wave works inland. Another, stronger wave will move into the area late on Tuesday. This will bring much heavier rain through mid week in Corvallis, with the first samplings of this next round of precipitation arriving Tuesday night
Tomorrow – Rain likely, otherwise dense fog and low clouds High 45, Low 34
Tuesday – A bit of clearing, with light rain early and increasing winds with heavier rain late in the evening, High 55, Low 42

NWS: Tomorrow – Showers High 46, Low 32
Tuesday – Showers High 46, Low 42

AW: Tomorrow – Mostly cloudy with a touch of rain High 54, Low 40
Tuesday – A thick cloud cover with a chance of rain High 54, Low 41

NWS: Tomorrow – Rain, mainly before 4pm. Areas of fog before 1pm High 46, Low 36
Tuesday – Rain, mainly after 10am. High 50, Low 41

WB: Tomorrow – Areas of morning fog. Rain. High 46, Low 38
Tuesday – Cloudy. Chance of rain in the morning…then rain in the afternoon. High 47, Low 42

WN: Tomorrow – Rain High 46, Low 36
Tuesday – Scattered Showers High 50, Low 41

We have a pretty nifty satellite image. The dense fog at the surface is easily visible from Portland to Corvallis. Looks nice everywhere else in Oregon, though.
