More Bouncing Temps…U.S. Snowpack Update

December 6th, 2012 at 8:16 am by under Weather

The temperatures have been bouncing, and this week was no exception.  We had mid 70s for highs last Tuesday…Now we expect mid 40s for today.  High pressure will create plenty of sunshine, but the northeast winds at 10-20mph will keep highs from climbing above 45.  As the high pressure area shifts around over the next few days then we will develop more southerly winds.  So highs will rebound into the upper 60s by Saturday.

Temperature Trend

We do expect a few showers early on Saturday, but the rest of the weekend is looking good.

I wrote a blog about the seasonal forecast for this Winter a couple of weeks ago.  I wrote how the conditions were shaping up for a decent chance for snow this Winter.  The U.S. snowpack is part of that scenario.  At the time that I wrote that blog, the snowpack wasn’t too bad.  Since then we dropped the snow coverage across America.  In fact now only 6% of the country has a snowpack.

U.S. Snowcover

This morning Bill Cairns on NBC’s “Today” said this was a record low.  I haven’t been able to find that on the internet, but I believe him.  Cold air has a tougher time lingering when there is a lack of snow on the ground.  So the cold air intrusions that will come out of Canada will have a better chance to warm-up or modify.  Not to say that we won’t build the snowpack in the north, but it may take a little longer.  That would likely delay snow at our latitude as well.  I still don’t think we’ll have a repeat of last year which was very warm, but I do think that snow will be tough to achieve for many parts of the country in the short-term.  A white Christmas may be rare this year other than in the mountains.  Stay tuned!
