12/10: Tuesday's Outlook and preview on Wednesday

GOOD MONDAY Evening all!

What a Cold Weekend we endured here in WY, as some of us or a few spots got down in the -10°s for the Overnight. 
As for the Monday Overnight, a 'slight' improvement to 14° here in the Oil City.

TUESDAY:
Warming up above Freezing and near the mid-30°s, BUT the winds out of the SW will slowly kick back up; giving the wind chill in the 20°s.  SE WY ( Eastern Goshen/Laramie Counties could creep in the middle 40°s)

2PM NAM TUESDAY FORECAST TEMPS.
As for any Snow Chances, keeping the 'Best' chance in the Yellowstone Region and NW Mtns as a little disturbance will trickle through.  Here are the Forecast Temps and the Precip. Map (BELOW)

5 PM GFS PRECIP MAP


















WEDNESDAY:  Thawing out even more East of the Divide nearing 40° in a few parts.  Keeping the breezy weather again, but NW WY will see a new disturbance push through from Eastern ID and SW Montana snaking in.  This will be a little stronger than Tuesday's, but the Wind River's could get in on this Snow.

2PM WEDNESDAY NAM PRECIP.

12/8: Saturday Morning Snow Talk... & Tribute to John Lennon

Good Saturday to Everyone!

Before I get to the Snow, I want to take time and pay my dues to the great John Lennon.  Lennon was assassinated on this date in 1980 in NYC at The Dakota by Mark David Chapman.  He was an idol to me growing up and an amazing voice for the Beatles and an activist in the Peace Movement.  Click HERE to see which song I picked as one of my Favorite Lennon songs.

SNOW TALK:
  1st Reports of the Snowfall from last night, in through this morning are coming in; and more is expected.

Click HERE for the Latest on the Snow Updates.




The RADAR (Above) shows that band of light snow pushing through the Bighorns and draping in the Bridger Mtns and near Riverton and South of Lander.  Reflectivity west of Casper is showing some precipitation around Hiland, but its not hitting the ground.  Should see some light snow showers coming in within a couple hours.  Up to an 1" is expected here in the city.

A PLETHORA of Advisories are out, but most of them will end in a few hours in NW WY.  Ahead of the Front, very blustery conditions again along the Wind Corridor in the Rattlesnake ranges and in the Shirley Basin, including the Southern Laramies.


This is out toward the Alpine Junction... Winter Wonderland for 'some' of us.  IF you are Traveling, drive safely on the bridges and overpasses and the secondary roads.

NEW UPDATE later.

12/6: Friday's Snow and WEEKEND Snow

Good Late Thursday to you all, but lets look forward to our Friday and this Weekend...very busy for this Meteorologist.

Here is the Hi-Resolution Rapid Refresh Model (HRRR) showing the this 1st Wave coming through giving some of light snow North of Casper and Riverton until 10 AM Friday.

--Not a big snow, but Light Snow for sure in the Yellowstone Region (not shown), Bighorns, and Black Hills. 

The Disturbance travels East along I-90 and just North of it in South Dakota and Central Minnesota.








NOT done yet, Our next wave (IMAGE BELOW) moves in from the West and ushers in more moisture for West of the Divide.  Casper will stay dry and cool in the 30s for Friday, but could see an another round of snow for the Bighorns again Friday Evening.

The 1st Wave will be long gone crossing into Minnesota and Northern Iowa where it will weaken.  Can't rule out an area of snow in the Sierra Madre's and Snowy's seeing light snow Friday Night.


Here is the RPM for 72-HRS out showing the total snow by Sunday Afternoon.  West of the Divide will see a good amount, but Wind Rivers and Bighorns could get a good dumping with possible upslope. 
What about Casper?...so far, Models are not fairing too well for us here.  Could see more than a few inches, if best, on top of the Mountain.

MAIN DISCUSSION:   I will be more concerned, not with the snow, but the Brutally Cold Temperatures along with it on Saturday Night.  Arctic Air will be sliding in from the North and IF the skies clear and HOW much snow, some spots will dip below-zero.

8AM SUNDAY MORNING TEMPS (NAM 0z Friday's Run)

12/4: Wednesday's Outlook

FIRST OFF,   Another Win for our Cowboys against the Redbirds of Illinois St!  Great defense and Free Throw shooting down the end continued our Undefeated Season.  For more INFO on the ballgame tonight,  Click > HERE


Weather Talk:

Continue with the Light Snow out West, but have backed off the Winter Storm Warnings for a few parts in the Valleys around Afton area.  Could see a few more Rain Droplets, than Snow.

Here is the RPM Accumulated Snowfall map showing that the Wind Rivers, Gros Ventres, Tetons and Southern Part of Yellowstone seeing the Higher Snow amounts for the next 27 Hrs through Wednesday Evening.
 

As for the Snow fall that will continue in the West, this will be the LAST Warm Day for us here in Central and Eastern WY for a while. 

Nearing 60° on Wednesday here in Casper, but Far Eastern WY could see the low-middle 60°s from Newscastle-Lusk-Torrington-Cheyenne.


I did say, 'for a while', here is why...

Much 'Cooler' Weather will continue as Arctic Air will plunge in from our North.

--Thus Dropping our High Temps below average about 5-10° & Overnight Lows possibly back in the Single Digits to Lower Teens if we get a good snow pack on the Surface. 

--LOOKING AHEAD...As I see the area of Alaska below average, I think we may be in that COOLING trend for a few more weeks..we shall see what the Pacific looks like and trends.

More 'SNOW' and Looking toward Christmas!

Seeing  the Maps and Graphics I have made on Monday, it was a busy way to begin this long week.

Why 'long'?  Well, another wave of Disturbances will slide off of the Pacific and incorporate some South West flow ahead and some Cooler North West flow from Canada behind it.

This is the, 5-DAY HPC, SHOWN ABOVE, map showing you the amount of Precipitation, mainly snow in WY, we could see through Saturday Evening.  We will have waves of Low Pressure, but I don't see any possible Jet Stream energy with these as the bulk of the activity will remain to our West in Idaho and Montana. 
 If I am seeing this right, maybe .10"-.25" of QPF here in Casper. 

Majority of this will remain to our Higher Elevation in Western WY; why they are under a Winter Storm Watch through Wednesday Midnight.

NOAA's Winter Short Range Ensemble Forecast (SREF) shows the amount of snow through Friday 2AM.  Western WY, Bighorns, Black Hills, and Sierra Madres will see a good chance of light snow.  Even a 'speck' could creep on Casper Mtn. 

CHRISTMAS LOVERS...Here is a great Map for y'all!
Remember...Snow Depth over 1" determines it to be a White Christmas.  With that being the case, Western Mtns, Wind Rivers, Bighorns. I'll be updating this Map about 2x a Week to see if 'Your' area will have a Bing Crosby Christmas (White Christmas)

HEAVY SNOW/ STRONG WINDS & A 'Pokes Win!

Before I get to today's Weather, something is brewing down in Laramie..

WYOMING defeated the CU Buffaloes down at the AA last night.  Click HERE for more.  Lets keep this season undefeated until Conference Play.

Okay,  Now its time for the Weather Briefing.  Let me go ahead and get to Central and Eastern WY.
Here are the Current Advisories for Snow/Wind for Sunday.

For the HIGH WIND WARNING, click HERE
--Side note:  It has been whistling as I have been typing this blog post.

For the WINTER STORM WARNING, click HERE.



Central and Eastern WY (Casper/Rawlins/Gillette/Lander) you know what I am talking about..Very Blustery.  Here is the forecasted 'gusts' at 2 PM.  Winds will remain sustained over 30mph through the rest of the day and early evening.

--Wind Rivers, Cody Foothills, Bighorns could see gusts at times over 70+ mph.

--Rawlins, and up to Casper is hazardous travel along WY 220 today and along I-80 to Laramie.

--Traveling to Gillette along WY 50 & 59 will be hazardous.




We are done with the Wind portion, but now lets set sail to the Snow out West.

Current 11AM Radar Image shows a break in the Snowfall, but MORE is expected should arrive from 2-5PM today.

Click HERE for the Updated Snow Totals after a small wave came through and dumped a few more inches earlier this Morning.



Here is the new 12z Run from the NAM showing the Snow filter in Western WY around 2 PM

--Snow Breaks loose West of the Divide, where the better moisture content is and Jet Energy is capable of producing Heavy Wet Snow.

--May take a little while for the Wind Rivers, since its just a little farther East.







Here is what the GFS looks like around 11PM Tonight:

--Snow will line up and could clip down toward Evanston and into the Salt Lake region.

As the system moves Eastward, could clip some moisture in the Bighorns, but with the wind and not as much Jet Energy, they could get choked off by the snow.  Still a chance of seeing light snow, though.

--Casper could still see that Mix for a brief moment late tonight, as the bulk of the snow will shift towards the Sierra Madre's.

AS FOR MONDAY,  Much Calmer but could still see a few lingering flurries in the Snowy Range and may slide in the Laramie's.

SNOW AMOUNTS & More Snow..plus, Windy WY Saturday

Good Saturday Folks!,

Don't forget...The 'Pokes are playing the Colorado Buffs tonight at 8PM on Root Sports.  Lets see if WY can take continue their undefeated season!
For a Preview of the Game, click HERE

NOW, onto the Weather..Here is the Advisory Map.
--WINTER STORM WARNING Continues through early Monday where FEET of Snow is still expected to fall.

--HIGH WIND WATCH along the Windy Corridor and along I-80 through the Passes in the Laramie's. This will be in advance of the Cold Front where we may see 50-70MPH gusts on Sunday.



I did say SNOW AMOUNTS in the Title, so here are the totals from Friday Evening through the Overnight.
Click >SNOW TOTALS: 1ST Round  for more.

Current Radar is showing the next wave coming in now..and continuing through the evening.

--West>East Flow is in good favor of Moderate Snow amounts currently in the Tetons, Togwotee area.  Moisture could creep up and start spreading North around the Jenny Lake area.  Plus, Northern Lincoln Co. is getting some light snow.







Here is the GFS for Sunday's Final Wave of Moisture; which I think could be the strongest.

--From 11AM through the Overnight,  Significant Snowfall is expected all along the Western WY Ranges.

--Through the Overnight, the moisture shifts East and could clip the Bighorns and Sierra Madre's.
As I say this, the GFS & EURO agree on that solution, but the NAM doesn't agree.

-Keep an Eye on this as it progresses.




IF ANY CHANGES, I'll keep you updated.
