Cool and showery today

Monday, October 14, 2013 at 7:36 am

Yesterday afternoon, the main front moved through.  You may have heard some rumbles of thunder and brief heavy rain, depending on your location.  As expected a westerly flow developed yesterday evening as snow levels rapidly fell.  Flow turned northerly a little faster than expected, which may have limited snowfall accumulations.  Looking at a combination of radar returns and webcam images, it looks like most locations saw at least a couple inches, but without ski areas reporting its hard to say how much.  Snotel gauges don’t do a reliable job measuring snow when there’s only a few inches on the ground so it’s hard to use those as an accurate indicator.

Currently, most showers have moved out for now except for a few mountain areas that are seeing light orographic snowfall.  There is also a fairly disorganized lake effect band south of the GSL over Tooele Valley.  You can see the lake effect band on the current (7:30 AM) radar:

Flow is progged to turn a bit more westerly today with a reinforcing wave of showers moving in later today.  This should add a couple more inches to the totals in the Wasatch before tomorrow morning when we start to clear out.

Models generally keep us dry for the rest of the week as strong ridging builds over the west coast.  We’ll be on the east side of the ridge so we will see warming up to around seasonal norms, but not as warm as our neighbors to the west.  Both the GFS and Euro hint at retrogression of the ridge into the Pacific during the last week of October, but at this point, it’s really hard to trust any models beyond 5 days or so.
