Clearing & Cooling Today - Dec. 14, 2012
Published Friday, December 14, 2012 9:18AM MST
Some snow in parts of the Capital Region overnight. That precip & some wind helped draw some of the warm air aloft down to the surface.
Temperatures hit +2 at 1am in Edmonton. But that's the warmest we'll be all day.
We'll have temperatures in the -3 to -6 range for most of the morning & early afternoon.
The wind is down though & skies are clearing this morning. The snow is moving off into E-Ctl Alta & Edmonton will get some sunshine for the late morning/early afternoon hours.
Partly cloudy skies developing later this afternoon.
The warmer air aloft is gone by this afternoon. The upper ridge is being replaced by a weak upper trough.
A stronger & deeper upper level trough will develop through the weekend. So...we'll cool off & get back to "more cloud than sun" conditions.
Looking LONG Range:
Temperatures are expected to slide into the -10 to -15 range for highs next week.
Winter "officially" starts 1 week from today & it appears it will being with a week of temperatures about 5 to 10 degrees colder than average.
That mean a "colder than average" Christmas.
Right now, the GFS ensemble is predicting a high of -18. I think that's overdoing it a bit (we'll likely be a BIT warmer).
But...based on the pattern as it looks now, I don't expect the Capital Region to be warmer than -12 or -13.
Edmonton Forecast looks like this:
Today - Partly cloudy & cooling later today.
Tonight - A few clouds.
Saturday - Increasing cloud.
Sunday - Mostly cloudy.
Monday - Mostly cloudy.
Tuesday - Mostly cloudy. 30% chance of flurries.
Wednesday - Partly cloudy.
