2/9-2/10 Inverted Trough/Mini-Coastal Storm

GFS has been very consistent and other models have had off and on a coastal/SE Atlantic major storm forming 2/6-2/8. 

 

Way too soon to say if it has any impact on mid Atlantic or north east but given pattern likely there will be a storm of some sort. 

 

Possible could be rain, snow, or nothing at this point, but chances of a storm of some sort in the SE/off the coast are very high.

We also need to be monitoring the NAO and AO for as we know when then are negative it favors the development of a storm and cold result.

If these 850s are right the BL would cool and it would S

Yeah, possibly.. I was just looking verbatim by the 540 dm line (only general guide) but there are several other factors like the net evaporational cooling you mentioned,  the lows track, the wind direction and sea surface temperature, etc..

Agree.  Would like to see the GFS come W like the Euro did at  12z ( although a scrape/ was better than it`s 0z  ) . The UKIE/JMA both drop throw precip west now .

00z GFS has a mod snowstorm for the area Tuesday. Miller B with wave 3 similar to euro and ggem. Huge pna spike with trough going negative very very explosive set up

yes but can't trust any solution of the GFS yet because every run is different then the previous runs and this last one 0Z looks suspect

Guys, since we have multiple threats (3) being discussed be specific as to what threat you are talking about. Discuss all threats in here. To make it easier, refer to them as Wave 1, 2 and 3 or threat 1, 2 and 3....really anything, as long as it's easily identifiable to people.

I'm usually not one to do this as I feel people should be able to look at these things themselves but to those who want to learn a little I think it would be helpful.

Current NYC 7 day forecast is dry for what we are discussing and temps above freezing.  Of course, the forecast this far out is subject to change.

BL is ugly I see. We'll see, what did the euro show for wave #1

 

That is prob saying 33 . 

 

Don`t look at the BL . - 2 850`s with that kind of precip you would drop right to 0c and it is SNOW .

 

Right now the UKIE is the most aggressive .

 

Both the Canadian and Euro forecast  lighter amounts however these have come W all year as we got inside 48 hours so there is still time for the guidance to tick W for Friday
