February is upon us - pattern change is in order

I’m not sure why we are forming some sort of linear relationship to low pressure mslp and the amount of moisture. I’ve seen sh*t lows deliver a ton of moisture thanks to isentropic lift. That depends more on the mid and upper levl flow. Whn you have a low from the Deep South, I’m usually not worried about its Mslp.

It may not look like an idealized art on that run but particulars with that look would create a very proficient snow wall/IB ... that HP is quintessentially oriented for incurring WAA/isentrope event

Agree. I like Wednesday...not a blockbuster, but could herald the start of the second half.

I was thinking a stronger system would have increased jet dynamics and better low level conveyors... sort of like stronger low, stronger H7-H85 winds leading to increased lift/moisture?  I was noticing it yesterday on the runs...drier runs had lower H85 winds and the wetter runs were stronger S/SW flow at that level.

I mean there is some of that, but I've seen a WF draped to our south with these POS waves running along it dump 1-2" of QPF before. If you have a nice high to the north and deep layer WAA...you don't need 70kts at 850 ramming into the region. Just good ole fashioned isentropic lift, aided by high pressure forming a nice frontal slope.  My comments were more for the pope saying that it's only a 1008 mb low. The pressure is all relative to the ambient environmental pressure. It's silly to say "well it's only 1008mb.." as if that matters.

Man the Euro EPS are looking real good this morning for all the mountains... that's a solid 5 day period between this evening's snow and then Wednesday. 

Out of the 50 individual members there isn't a lot of spread, much less than yesterday.  They seem pretty dialed in but we know how that's gone this winter with performance in the last 84 hours.  Just a widespread 1-1.5" QPF gain for the mountains as frozen over the next 4-5 days.

Ah that makes sense, thanks.

The S VT areas are not looking great tonight so need to cash in on Wed.
