Melting, Groundhogs, Humidity, And The Big Game

January 31st, 2014 at 7:47 am by under Weather

Despite all of the topics in the blog title, this will actually be a fairly short blog.  While we’ve had a lot of wintry weather lately, we’ll finally see some warming and melting today.  Temperatures will rise quite a bit from this morning’s lows.  We’ll get into the mid-upper 40s with lower 40s north of the metro and on the Peninsula.  Skies will be mostly to partly sunny.  Winds will be light and southwest.  The southwest winds resume tomorrow.  So we’ll warm up to the mid-upper 50s.  We’ll be in the 60s by Sunday.  It will be a heat-wave!

The average high for this time of year is 49 degrees.  No big weather systems are headed our way in the short-term.  However, a lot of rain is going to move-in starting on Sunday.  During the day we’ll only have a slight chance for a shower, but we’ll increase the rain chances during the evening and overnight.  Yes…this means that we’ll see a few showers around while you are heading out for Super Bowl festivities.  But I’m hoping that most of the rain will hold off until after the big game.   During the day on Sunday we should only see a slight chance for a shower.  In fact I will be enjoying the warmer weather up at the Virginia Living Museum where we will see what the local groundhog sees.  Come on out and have some fun.  The ceremony starts at 2pm.

From Sunday night into next Wednesday we are looking at rain showers in the region.  A couple of fronts and a developing area of low pressure will be the cause.  Things look too warm to have any frozen precipitation, but there may be some in the north/west part of Virginia.  Also, we could see a brief changeover at the very end of the system.  With all of the snowmelt, it’s possible that we may have some flooding next week.  It’s still early to make that call yet, but that is something that we’ll have to keep an eye on.  The ground was saturated even before this snow.  So we’ll talk about that more over the next couple of days.

Finally…water water everywhere, but dry in your home.  When outdoor temperatures drop as much as they have, then your heater works overtime.  This creates a huge drop in the humidity in your home.  It is a lower (relative humidity) as the air temps are typically between 65 and 72.  Meanwhile the dewpoint (another measure of moisture) is in the teens or 20s.  the bigger the difference between the 2 creates a lower relative humidity.  One time in Illinois we had a hum-dinger of a cold spell.  It was very similar to the one they had recently.  The heat was cranked up in my college home, and temps were in the -5 to – 15 range outside.  So I measured an indoor relative humidity of 7%.  That’s drier than some deserts.  So you may have a humidifier in your home to cope with this effect.  Here is a great article to try to naturally put more moisture in your indoor biosphere: Natural ways to humidify your home.

Enjoy the warmer temperatures this weekend.

    I remember back in the early 2000′s, I think 2002 or 2003, we got a lot of snow like this but I can’t remember how much it was. I tried looking for it but I couldn’t find it. Is there a specific site I can look at for that total?

      Hi Crystal. We had a big snow the day after Christmas 2004. That was my first big snow, and my first big bust. I came in August 2004. So I don’t know much about snow before then. Except for some of the bigger events. Jeremy

        That actually might be the one I’m thinking of. I think it was very close to the same amount we just saw, if not a tad more. Thanks for your input!

    Hey Jeremy….are there any snow storms that you have your eye on?
