Cold Tuesday And A Damp Forecast. Weekend Looks To Be Wet Again, Maybe Icy In Mountains

Good Tuesday Morning to you.  I hope you are having a great start to the week.  I have been enjoying the Olympics indoors since the weather has been kind of dull and gloomy outside.  Go USA!  Well weather wise I'm afraid I don't have great news for sunshine.  A cold front to our North has stalled allowing disturbances to ride along it.  The front moves into our area for the weekend but not before a warm front moves North tonight and into Wednesday, breaking down the current Cold Air Damming Event. 

Out the door this morning there are patches of drizzle and areas of fog.  If you are traveling in the mountains this morning use caution because just enough freezing drizzle has fallen up there to create some slick spots on roadways.  Those slick spots are limited to the mountains though.  With temps in the low and mid 40's across the foothills there is no threat of ice.  Highs today will not be much above where they sit right now.  Expect mist and drizzle off an on through the day.  Here is a look at the temperature changes over the last 24 hours.

The normal high for today's date is 52 and the normal low is 29 making a daily average temperature of 40.5 degrees.  Even though it will be chilly, most areas will still be just above that average today.  Here is a look at the high temps compared to average over the next 6 days.  Saturday/Sunday will likely change though so don't focus too much on those numbers.  It appears that colder air could be around Saturday into Sunday, more on that in on down.

As you can see above Thursday is going to be pretty warm.  There will be showers around the area but temps will be near 70 as an upper level ridge of high pressure in the Gulf of Mexico funnels warm air North.  It wont last though.  We hold onto shower chances though as a cold front moves in on Friday and stalls.  Another decent shot of rain looks like it will come through Friday Afternoon.  As the front stalls waves of low pressure will move east along it.  Saturday this becomes interesting an interesting setup.  A strong Arctic high will be supplying cold air down the East slope of the mountains and will develop a cold air damming event.  At the same time low pressure pushes precipitation into the area Saturday Evening.  High temps on Saturday look like they will reach their high at Midnight Friday Night/Saturday Morning.  From there temps will fall as a backdoor cold front moves into the area.  Big questions remain as to how far south that cold air makes it and as to how deep it may be.  There could be a mix of rain, snow, freezing rain or just plain rain.  Its something we will continue to monitor as the week moves forward.  Important to note that the European model is much warmer with this system and keeps it all rain Saturday through Sunday.
