Quick points for those of you who don't like rambling...

1) I am flying out to SW Colorado at 6am on Saturday from Albany. Will be
there next week and won't be back in Burlington till a week from Sunday.
I'll likely have internet access but not sure how often I'll check it so if
a storm pops up, stay with the NWS guys or Josh Fox (at MRG); they'll destroy any
other forecasts.

2) Pattern goes zonal next week and we are flooded with mild, Pacific air.
At this time of year, once we go back towards normal or just a tad above
normal, rain becomes an issue especially at lower elevations. I think next
week sees some marginal events where it might be snow on the mtn tops with
light rain showers in the valley. Do not foresee any major precipitation
events or major wash outs. Heck, some of the days could bring perfect
spring skiing with inversions leaving the upper mtn near freezing at night
and the valleys in the low 20's...while the days are in the 40's with sun.

3) The last 10 days of March look to be back into a colder
regime with plenty of cold air still hanging tough over Canada. The
operational GFS has been showing us tapping that towards the end of the
month and would bring some late March snows. I do not see anything to worry
about at this point as far as an 80-90 inch snowpack melting in a week. We
might settle back into the 70's but overall, I believe much of Vermont is
primed for decent spring skiing before one last return of the snows.

Discussion/Musings...

First, wow what a cold night we've got on tap tonight. The NWS mentions
possible 40 below readings (that's ambient temperature, not wind chill) and
is going with record cold across the area. Then we see a 40-50F swing
during the day tomorrow as highs get up to the teens/twenties. Tomorrow
morning's lows should be quite interesting.

Moving on to the weekend...
Here's the NWS forecast for Mount Mansfield at 3K feet:
-----------------------------------------------------
Friday Night: Mostly clear, with a low around 17.
Saturday: A chance of snow showers, High of 36.
Saturday Night: A chance of snow showers, low of 19.
Sunday: Mostly sunny, with a high near 39.
Sunday Night: Partly cloudy, with a low around 22.
Monday: Mostly sunny, with a high near 39.
-----------------------------------------------------
Valleys have chance of rain showers but the mtns are showing chance of snow
showers and then we break into what should be a few days of excellent spring
skiing. Wall to wall sunshine with highs on the mtn in the upper 30's and
low to mid 40's in the valleys (same exact forecast was given during that
week long stretch of great weather, just to give you an idea of temps) and
with low humidity, expect the snow to stay in better condition than it would
with those temps and clouds. Overnight temps should fall like a rock with
good radiational cooling before warming up during the day. Valleys could
see some 30-40F daily swings that are indicative of sugar-season.

Mid-week comes and things go a little bit downhill as the front sitting up
in Canada allows for some waves of low pressure to ripple along it. The
case could be here that areas north of I-89 have the best shot at widespread
clouds and some light precipitation in the form of wet snow up top and light
rain at the bottom, while south of I-89 sees a little less of the
clouds/precip and more in the way of great spring conditions.

Long term progs (8-10 days) of the European Model and the GFS show lower
than normal heights and colder than normal temperatures in that time range
with a mean trough setting up across the northeast. This is how I think
we'll spend the last ten days of the month so while it might get a little
mild, it doesn't look like anything out of the ordinary for March and it
certainly will not be going to the opposite end of the spectrum from right
now (ie. record warmth). I think we've got one or two good snows left in us
for the end of March and possibly early April.

Some stations are saying 70s for SNE next week. Unless it lasts for a REAL long time, I don't see the snow going anywhere anytime soon. I noticed Wachusett had about a 4-5' base on the summit trails tonight which is the most I've seen in years. I can't imagine how deep it is further north.

Not in the northeast.....but how does the west look as far as general temperature trends from St. Patricks day through the 24th? (Wyoming specifically)

Thanks Scott. I am heading West the first week of Apil and cannot decide between Whistler or the Tahoe/Mammoth area. I know predicting two days out is tough let alone a month, but what do the long-range models look like for late March/early April in the western half of the continent?

I am just trying to figure out what pattern is shaping up....trough in West or East by then?

Late March and early April look to be mild and dry across much of the southwest with more seasonable temperatures and chances for precipitation across the northwest. My bet would be, based on how this winter has panned out (low snow at Mammoth, record snow at Whistler), I'd head to Whistler. I think areas closest to the southwest (Four Corners region) will have a mild, dry spring with a lot of high pressure.

Wyoming should be generally at or just above seasonal temperatures though precipitation chances could go either way right now depending on where the jet sets up. I think we see some ridging in the west but how far north that ridging extends is hard to say. Jackson Hole could be on the cusp of a snowy pattern but me thinks the snowier pattern sets up further north into southern Canada and up the B.C. coast...though Front Range sliders have to be watched out for this time of year and can quickly turn places along the Front from MT/WY/CO from rags to riches very quickly.

Its spring skiing in the west...corn production will be high across many areas that see the warmer temps so I wouldn't worry. I'm heading out to SW CO where it hasn't snowed much this year, and the base depths are actually less than they are on my home mtn of Mount Mansfield right now, but its still the Rockies and fun will be had.

looks like sunday could be a little bit of a dust on crust scenario. Mild temps and some rain for saturday then temps not getting out of the high 20's at elevation on sunday. Prayin for warmer temps on sunday. i know that sounds like blasphemy but i'd love it if it didnt freeze solid at sugarbush.

Well, looking at all the weather sites I know of, none are predicting more than 60F for my location in the middle of NJ next week, and they are then showing things getting colder again next friday or so.

Looks like freezing rain on Saterday for the Catskills. Might not be worth the drive. Hope the drive up to Stowe on St. Pats day is worth it though.

Upper elevations might be dust on crust but I bet the lower elevations and non-north facing slopes get into the mid to upper 30's softening up the surface layer. Just follow the sun and at the very least, it'll be a gorgeous sunny March day.
