January 2017 Observations and Model Discussion for the Pacific Northwest

[TT-SEA]

Huh, was 34 but in the last hour temp has dropped to 30 again. Everything is glazed and freezing back up

 

 

Where?

[TT-SEA]

Wind speed/direction?

 

From the east and very strong.   

[Jesse]

Where?

Whatever part of Washington has a jsf343 zip code.

[Jesse]

PDX back down to 32.

 

DP has dropped back to 28 too. Was up to 30 earlier.

 

31 here and maybe approaching 2/3" ice.

[bainbridgekid]

Actually seeing a lot of big wet flakes mixing in with the rain here.

[MR.SNOWMIZER]

Portland-Longview lands in between storms. Love it.

Ive never seen a low come onshore north of Astoria like that and not hit the puget sound. ??

[jsf343]

Corbett, on Larch Mt. it is actually snow now mixing with freezing rain and sleet, kind of bizarre. I wasn't expecting that seemed like things were warming up and the big thaw was on, but maybe not so fast.

Very strange, and pertinent data for us east countyers. Cooler upper levels are not progged to begin moving in until maybe 10 tonight (850s are actually near their peak right now) so not sure what is causing the cooling up there.

It basically gets swallowed up by the bigger low to the south as NE flow increases rapidly.  

[MR.SNOWMIZER]

Temp has fallen to 34 here and snow is mixing in. Wtf

[SilverFallsAndrew]

Salem and Albany score with the 18z GFS , stronger low not filling as rapidly.

I currently have anything that can possibly fall from the sky...falling from the sky!

[Timmy Supercell]

Moderate rain now. KLMT may not be reporting this (when do they ever? lol) but it's significantly increased in intensity.

I doubt you're getting hail.  

[jsf343]

More snow mixing in. Very unexpected but I'll take it.

[Dave]

Only 3 days away.  This should verify, right?

Amounts look solidly underdone for Eugene.  

[Kayla]

PDX back down to 32.

 

DP has dropped back to 28 too. Was up to 30 earlier.

 

31 here and maybe approaching 2/3" ice.

 

Moisture just keeps filling in to the SW as well... 

[MossMan]

I doubt you're getting hail.

Maybe!

[TT-SEA]

Getting icy out there... mostly sleet here.   It bounces off you.  

 

[Jesse]

Maybe!

Frogs?

[Jesse]

Moderate rain now. KLMT may not be reporting this (when do they ever? lol) but it's significantly increased in intensity.

You will likely change back over to snow later tonight.

[MossMan]

Frogs?

Yes...including Dolts sad one.

It seems clear that the models want to continue the trend of splitting a lot of the energy near us next week. Means not a lot of widespread fun, there will be fairly localized winners and losers for the most part.

[ShawniganLake]

Temp has fallen to 34 here and snow is mixing in. Wtf

Didn't you have a WSW for your area today?

[Timmy Supercell]

Wunderground.. please stop feeding more crack to my hyper frog. lol

Maybe for a brief period. The majority of the precip through tomorrow should still be rain or very cold rain.

[Jesse]

It's refreshing in a way to see someone here wishcast for rain over snow.

[TT-SEA]

Almost all snow here now.   I have no idea how that can happen with the warm air aloft.   

[Jesse]

Could be some thicker cold air in your area thanks to the gap in the Cascades at Snoqualmie. Combine that with some wet bulb happening in the mid levels like we saw yesterday and that could explain the changeover.

Take a light bulb (preferably LED) and pour water on it. It will start snowing outside.

[bainbridgekid]

Saw this picture of people skating on Green Lake yesterday.

 

Doesn't look safe at all, but the fact it was even possible is incredible. The area by those diving boards is at least ten feet deep.

 

[ShawniganLake]

Almost all snow here now.   I have no idea how that can happen with the warm air aloft.   

Over 2" here, even though the 925mb temps have been shown to be well above freezing all day. 

[Deweydog]

The east coast sure looks toasty for the foreseeable future once this cold snap abates.

Do you have a link to the current upper air map.   I would like to know what the actual 850mb and 925mb temps are here right now.  

[crf450ish]

Timmy_Supercell, your avatar is epic.

[TT-SEA]

Wind has completely died... its calm here now with moderate snow.     Not even any ice pellets.

[Jesse]

Get that southeast ridge building for our late January kill shot!

They need to torch all winter
