Monday Morning Pattern Update: Spring for Mid-Atlantic

Good morning everyone. Well, spring is certainly in the air. We discussed last week how this would occur and now we are seeing it in full swing along the eastern 1/3 of the country. Birds are chirping, flowers down near the Mason Dixon line are sprouting, and snow is melting. Out west, the mountain regions are seeing and will continue to see the action over the next 2 weeks. Expect multiple episodes of snow for those mountains. That is great for the ski areas.

So is this really it, is winter over? For the mid-Atlantic south I really think so. For New England, I wouldn't make that call yet. I can see March being a active month up there for the ski areas.  Overall it just was not in the cards this year for the Mid-Atlantic region. Most areas are well below normal for snowfall and well above for temps. Up in New England, northern areas have actually done very very well while areas near Boston have been around average. 

The warm pattern continues over the next 10 days...

You can see the trough of cold air/low pressure out west and the warm air in the east in the image above. This has been the theme of the winter and I see no reason why this will not continue into March as the models show. 

Looking at the tropical pacific, a pattern of tropical convection called the MJO also supports this as it may head into its phase 3 as we enter March. Think of the MJO as a cluster of thunderstorms that moves through different regions in the tropics. It influences the jet stream.

This is what phases 3 tends to produce..


Notice the trough hanging west and evidence of ridging of high pressure in the east. This is not far off from what the models shows.

So can this change? Maybe as we head into the 2nd-3rd week of March but I would not count on it. Sure we can get big mid March storms, but my gut tells me its just not that kind of year. Up in New England ski areas I can see a better shot at this. 

It will not be long before we are discussing severe weather season which could be active this year. 

Look guys, no one loves winter more than me. I hate to see a snap like this into early spring, but its just the reality staring us right in the face. I am not going to "search" for cold and deny reality. Mother Nature always have a few surprises up her sleeve so let me be pleasantly surprises. Until then, I will be polishing up my golf clubs for spring.

Wednesday Morning Weather Discussion: The S Word is Becoming Relevant

Spring, thats right. It will not be long before spring takes it hold on the Mid-Atlantic. Now I am not like most people, if it was up to me I could have winter until May but that's not the way it works. With the exception of northern VT,NH and Maine it has been a pretty below average winter for snowfall. It just was not in the cards for us this year. Some years it wants to snow, others it doesn't. This year it was clear it wanted to snow out west and way up north. But hey, at least we got something. 

Winter is never officially over in my book until the 3nd week of March. However, when it comes to this year the window is shutting rapidly. We will have a big warm up next week followed by a wildcard, rabbit out of your hate type set up for a storm to develop late next week. This means it probably will not happen. Heading into early March one last gasp of winter is not off the table but it is too early to predict that at this time. Overall we are clearly in the 9th inning here.

A storm that could have been is missing us to the east and will hook back into Maine tonight with more snow...


Maine currently has a 50 inch snowpack in spots and this will add to it. It has been an epic week for that state. Areas in NH,VT and eastern Mass also will see snow from this. Expect several inches there as well. This was sooo close to being a big storm for everyone. 

Here are updated snowfall projections for this...

 
Moving onto late this weekend into next week, a surge of warmth...


Storm activity will pick up late next week but the models are trying to sort it out. You can see below it shows a lot of activity on the maps...


We clearly are not going to have two side by side storms like this. What will likely happen is one big storm that cuts inland with rain. The chances at snow are there but very slim. Everything would have to be timed perfectly.

That is all for now, more to come later this week.

Monday Morning: Close, But No Cigar?

Good morning. As a major snowstorm currently bears down on Maine the natural question is will a big one hit our region? The ironic thing is we have a set up this week that can support a major storm but it does not look like it wants to come together properly.

Before we get there, lets look at current radar over Maine..


You can see bands of heavy snow over the state. We should see a lot of snow amounts close to 2 feet near the coast. In Mass and surrounding areas over a foot was reported in many areas. Not bad at all!

So moving on, we have a very interesting set up this week in the weather pattern. Two main things to focus on: Energy moving in from the SW corner of the United States and energy diving down from Canada. I highlighted these features below..



Now in addition to these two pieces of energy, notice the ridging of high pressure over the west coast, ridging of high pressure over Greenland and a vortex of low pressure over northeastern Canada. All off these ingredients are in the recipe for a major east coast storm. If everything aligned properly, and those two pieces of energy combined along the east then the storm blows up. However, just because the ingredients are there does not mean a storm. It has to come together properly and right now that does not look to be the case. 

The timing of the two is off as labeled below..


This results in an offshore strung out wave of low pressure..


Now can this change? Yes, it can. I have been watching this very closely for several days and although it has trended better it is still not there. By tomorrow morning we will know for sure the fate of this storm threat but at this time I say its a 25% chance. We need to see major trends in next 24 hrs from models. They need to speed up #2 and slow down #1. Considering the departing storm over Maine currently can play a role in this, it is not out of the question. We need to see how the models handle the departure of that storm.  Stay tuned for updates on this.

Following this near miss, things then warm up next week before maybe one last gasp of winter around the last 5 days of Feb. The season is ageing guys and if it doesn't snow again soon most areas will stay below normal for the year.

Thats all for now, more to come.

Major Snowstorm To Bear Down on New England

Another major winter storm will take a grapple on New England Sunday into Monday with wind driven snows near the coast up into Maine....


The storm rapidly intensifies in gulf of Maine with winds battering the coast...



Further to the south there will be mixed precipitation as storm approaches tomorrow in areas of southern NY and northern NJ..



We will watch this closely and see how far south the colder air can get. Regardless most of New England especially Maine will see 1-3ft of snow!



Boy did I wish I lived in Maine this weekend, this will be some storm.


I still also have my eye on the end of this week. I will comment more on that tomorrow.

Friday Morning: More Action Looms

Good morning. It turned out to be a powerful storm yesterday. Many areas from NNJ into New England saw 8-14 inches of snow with some very high local amounts.

Here is a verification of my forecast.....



Overall not too bad. I got the 1-3 in Philadelphia right but was a little high for some parts of south central jersey. I was a little too low for areas of New England. Notice there is an isolated 19 inch amount near West Hartford! I give myself a B+ on this one.


So moving on, the folks in New England have another major snowstorm on tap for early next week!

Check this out..

Sunday night..


Monday..


This is a major storm. A upper level short wave dives down from Canada and completly closes off into a rapidly deepening storm. Areas of NYC are too far south on this one and see rain with potentially some light back end snow. 

Here are GFS models estimated snowfall totals (click to make bigger). I will make my own map tomorrow...


We then have to watch for another storm threat late next week. We have very impressive players on the field for this one I am just not sure if they will come together correctly....


Big ridge out west, ridge of Greenland, low pressure vortex near 50/50, and two pieces of energy from northern and southern jet stream. We need that southern piece of energy marked by the X to eject faster. IF that happens and it combines with the northern stream X then we get a major storm. At this time I say chances are 35%.

So winter is finally here guys. New England gets another significant snowfall and areas to south are still in play next 2 weeks. Let see how it all plays out. We need more snow to save this winter. 

More later.
