Severe weather outbreak, including tornadoes early next week. Plains Monday, Midwest Tuesday. You can't get a tough this deep coming into California without severe weather 2-3 days later. Chaos to Clarity breaks down the pattern. Watch here:
It is my honor to introduce my son Reeve Lynn Rayno.I now have an amazing son to go with my beautiful wife,Tyler.He was named after 3 great men.(1) Ken REEVES my friend and mentor-RIP (2)Terry LYNN Ishler, my wife’s father (3) Bernard Joseph RAYNO my dad-RIP. Off from weather.
find it amazing how many "know it alls" there are during a snow storm. I have meteorology degree from Penn State, 30 years of operation forecasting yet I am humbled everyday by the atmosphere. I realize that there is so much stuff I need to learn and get better at.
Models didn’t miss the snowstorm across the Northeast, I did. blaming a model for a bad forecast is a cop out and just plain embarrassing. The models are suppose to be tools to make a forecast. I missed this forecast not due to a model but due to forecast choices I made.
and as a I predicted those that were telling me that the storm was over and that I was way overdone in NYC and Philly are now telling me that I need to raise my amounts. It never ends. I will be back later.
Everything I look at says watch East Coast Monday into Tuesday. The ECMWF (left) weakens and strings out the trough with little or no storm. However GFS and CMC (right) both show a sharpening trough approaching the east coast resulting in a storm. I lean toward GFS and CMC
Potential for accumulating snow from Midwest to Northeast Thursday into Friday. Key is digging N branch trof (providing cold air injection) and upper low, currently off SoCal coast, running out ahead of the northern trof...As usual, timing is everything and this is 5 days away.
During a NE snowstorm there is a ebbing & flowing with model data (shifting west & east).This occurs frequently with the SFC/QPF. This is why I focus on 500mb.This is referred to as the Windshield Wiper Effect.Many who thght I was overdone with snow will now tell me I'm underdone
Here is an updated map or two for late this week. Dark blue is where blizzard criteria will be met. Draw a line from from Kansas City to St Louis. North of that line is 6+". The light blue is a 1-3 ish area. Also there will be the potential for a flash freeze.
This is a very tricky forecast for the Northeast Thursday. Perhaps the GFS is to cold. However, this is arctic air which tends to move father south than you think. I would not discount the GFS at all.
Something to watch. I here my gumba
@BigJoeBastardi
mentioned a few days ago.This is Sun Feb 4. UL in New Eng delivers a shot of colder air before lifting. Southern UL has room to comes north. Dump of snow on northern side across mid-Atlantic. Lets watch.
I am firmly on board with a big storm late next wk. Digging trough/injection of arctic air argues for a sizeable storm. The map below is my "first forecast". The actual snow area will be small than this, but this is the "threat zone for a snowstorm" IMO.
@breakingweather
I did figure out how to do twitter live, I needed to update the twitter AP. I am planning on a twitter live tonight at 8pm (after I put my son to sleep). If that changes I will send an update out. Join if interested. I will discuss the Northeast snowstorm.
IMO.There are many ripping the computer guidance.I think the models have been fantastic. Highlighting a big storm more than 10 days away.Anyone that is looking for the exact details a week a way you are using the models as a fcst instead of a tool to make a fcst.
you know its been a quiet winter when going 3-6" when someone else is going 1-3 turns into a huge talking point. Then again, that's the life of a meteorologist that I signed up for.....many years ago when I had the best mullet, wore ripped jeans and had an earing.
I am very skeptical of the 12z EURO. Stalled boundary with along the gulf coast with arctic air across the Midwest and additional energy dropping south tells me there is a storm threat along the coast Monday into Tuesday. I am going to continue with that messaging.
I owe you a map for early next wk (Mon-Wed) so here it is. Everything I look at tells me there is a storm threat along the east coast next week. So much so that I am ignoring the ECMWF. For most the snow accumulation will be less than 6. The exception would be eastern new England
A week from now. key is the upper low across New Eng. Does it drive the southern piece out to sea or up the coast. the circle along the western end of the trough currently drives the storm out to sea.If the mean trough is further west then its up the coast and a big snowstorm
I see 18z GFS shifted west. I suspect the shifting west will continue over the weekend. However, there will be a shift back to the eas, I bet early next week. I will try to a video over the weekend. But as you may guessed I like my snow potential map.
This is the set-up I have been waiting for.Trough digs into East (GFS-Sun am) if energy across southern branch can run out of ahead of trough,a storm will move along the coast or further inland, if southern energy lags it is out to sea.All scenarios possible.
@breakingweather
STATEMENT FROM BERNIE RAYNO (LOL, I always wanted to write that): I have seen this many times in the past. You ride the NAM on this, it isn't perfect and will likely be overdone in some areas, but overall it will out perform the GFS and EURO. Twitter live at 5:45 am.
@NsfwWx
. I did mention you in my latest twitter live pertaining to our conversation pertaining to the southern piece of energy. I did so since you brought it to my attention. I always give credit. Good luck with storm
If you are a snow-lover you have to be excited about the overall weather pattern. There are multiple shots with the first major threat Sunday into Monday. There are others. Video is coming...
Long way away, but this is very precarious set-up along NE coast for Lee mid-next wk. Where does trough set-to in relation to Upper high? Will there be enough trough to steer east of U.S. I am unsure and euro 8pm next fri looks scary as lee would be drawn toward U.S.
Windshield wiper effect.Old euro on left,new Euro (upper right).Euro has shifted west & I think the GFS will follow suit at 00z run ton. My forecast remains unchanged.I believe the upper low track will be west of I-95 & a midwest track is possible. shifting guidance will continue
Follow the trough. No question the GFS (left) has shifted west with axis and tilt.The ECMWF (right) hasn't changed location, but upper low cuts off sooner.I don't think the GFS is far enough west with the precip. SNOWSTORM.I still like my threat area for now. Twitter live at 8pm.
so you say there is a chance.. in about 10 days are some ingredients for at least the chc for snow in the Northeast. It starts with a true injection of cold air while energy comes into the west coast. The time frame would be around Jan 1-3
#Northeastsnow
Video coming later today. While there will be a general 1-3 inches with storm thu night into Fri. There will be a band of 3-6 on the northern edge of strong shortwave moving across VA. I have the area highlighted.
95l will be a hurricane this week and probably a major as it moves north of the islands late this week. Precarious set-up by mid-next week. While trough off eastern seaboard should pick it up, if it missed the connection than look out NC coast on north. More on this tue am
Is it so hard to believe that someone ( meaning me) is willing to try to forecast not what the models are showing 3 and 1/2 days prior to a storm but what they think is going to happen based on simple meteorology?
SNEAKY SNOW FRI NIGHT. Injection of cold air (left) pushes into mid-Atlantic Friday. Digging trough (upper right) & lead shortwave will produce snow from Midwest to mid-Atlantic. Strong upward motion (lower right) with 1-3" of snow with isolated amounts of 4 or 5"
it's been a long day. I am off twitter until early tom am. While I tossed the Euro earlier today, the concern is that Euro has right idea, that is a push south. While most storms shift back & forth, this storm's windshield wiper effect has been on steroids.
I have no changes to my thinking.Very early in the game. (1) injection of arctic air argues for a snowstorm and blizzard is in the conversation. (2) unsure on exact location of digging trough (3) Windshield wiper effect warning as guidance shifts (4) Widespread cold Christmas day
First periscope of the winter season coming this evening...I will release the time when I know, still at gym. A setup we see every winter is on the way. I do appreciate anybody taking time out of their day to watch...I will try to keep the waffling to a minimum...maybe
(3) More importantly there is FRESH INJECTION OF COLD AIR Sat nt-Sun. Look at the sfc map Sun A.M. (ECMWF).THIS IS A TEXT BOOK Sfc map for a NE Snowstorm. Strong H in New Eng with a developing L to the south. We have a long way to go, but everything is there.
@breakingweather
let the games begin. Snow and ice west of I-95 Friday into Saturday. Is it mid-atlantic or Northeast. The key is the location of the Upper Low. Euro to the left points to New England, GFS on right points to Mid-Atlantic. Not sure yet.
set the alarm for Thu. Here is the set-up. Split flow. Northern branch brings in the cold while southern piece (circled) is the storm.Does northern piece suppress southern piece or steer to the north. My snow area (if there is a NE move) on right. EURO shown (left)
Split flow early next Sun.ECMWF (left) is from Sun eve. Southern branch energy needs to run ahead of northern branch (for snow) if not,it gets buried across the Southeast resulting in rain not snow. My snow area is further where I think the cold arrives (if storm is guided north)
Many are asking about what happened with this storm. Why the missed forecasts? It’s simple there is too much emphasis on model qpf and not enough focus on basic meteorology. I even lowered my totals (based of stupid qpf) which caused my forecast to be underdone in areas.
While we are in between storms...I ran across the 1990 Penn State year book (the year I graduated ). Can you find me without looking at the names on the left? Hint, I had more hair than I do now.
Sun night is family night. Getting off X until tom am. It appears I am on an island..again. My forecast remains the same. I believe my meteorology is sound and I will stand on it. I will change my forecast when I believe it is time. It's not the time.
No changes in thinking. I like this map. 12z Tue guidance buried the storm across the SE, then 00z runs brought back to the North. Expect these swings back & forth to continue. If the storm takes a northern track it will likely strengthen as it approaches the coast.
Nothing has changed with my thinking. Below is the 7am Mon ECMWF (GFS is similar). Does the northern branch drive the southern piece up into the mid-atl or south across the Southeast. Air north of the system is cold enough for snow. I will post a snow map where I think it can be)
Monday we start with the widespread snow and ice threat from Texas to the Midwest to the Northeast. Another arctic surge of air with a slow moving trough. these are tricky. Time frame is Tuesday night into Friday.
Icompare the 00z (last night) GFS 500 mb to the 18Z (Current) 500 mb for 1pm sat. Overall the trough is stronger & now instead of energy rocking east south of the Cape (00Z on left), the upper low is cutting off (18z right). The outcome a push west of precip. My forecast stands
Very interesting along the East Coast Tue next week.12z ECMWF control run as a weaker trough compared to 00z run which means flatter wave & a better chc for snow along I-95 from DCA to Boston. I discussed this in my podcast which is pinned to my page. Tue eve maps shown below
18z gfs holds it positioning upper low.I think the GFS upper low placement (farther south & east) is better than the ECMWF. I think the shortwave coming into BC will be able to dig farther south than EURO shows. Far south means as it lifts it will be farther east.
EURO 7pm Wednesday Jan 3..this is razor thin at either OTS or up the coast. If it is up the coast it has arctic air to work with..(1) shows the southern piece just out ahead of N trof (2) shows the northern trof which has just gone negative tilt. Very close
The modeling with Florence will change throughout the wknd. The current EURO/GFS tracks are likely wrong in some way.If u understand the why,u may be able to anticipate future changes.I try to do this in periscope.I want to make sure I use the model as a tool not as a fcst.
Interesting that the gfs showed this yesterday, energy dropping into southern trof resulting in the push north of precip. This, IF correct would push snow further north
I am issuing a "Windshield wiper warning" for Lee late nxt wk.There will be swings back & forth with modeling, the same swings that occur with snowstorms.I am focusing on the strength/positioning of the incoming trough late next wk to determine the track.
last thought for a while.This happens in almost every storm.The windshield wiper effect.The shifting west then probably east again will go on through the wknd and into next week. My overall thoughts & snow potential remains the same.A snowstorm is coming, blizzard is on the table
What a next 10 days. Blizzard across SW Plains today, Midwest snowstorm ton into Tue. Next and stronger storm further east for the Midwest Fri into Sat could evolve into a blizzard for cities like
#Chicago
. BTW watch out East Coast early next week.
There is no way I am issuing specific snow accumulation forecast this far out. Having said that I like the snow potential map we issued yesterday. Anywhere in blue is where I think the storm will have an impact, threat for 6" or more. More details here:
