In Edmond, we're at more of an ice pellet / sleet precipitation form (perhaps even some snowflakes mixed in), with the ground starting to turn white in places. The cold air is stronger and faster-moving than the models were forecasting a couple of days ago, and this may actually help ease the ice storm threat across central Oklahoma I think... If the cold air is deeper than was previously forecast (which may be a first-order guess given the faster-than-forecast speed and intensity of the cold air), we may be dealing with more of a sleet event north of I40 and I44, with the freezing rain more dominant across south-central and south-eastern OK (and adjacent portions of northcentral TX). I guess we'll know more after the 18z OUN sounding. A sleet event seems to be significantly "better" than an all-freezing rain event or an all-snow event (since 1-1.5" of liquid equiv would likely yield more than a foot of snow). Sleet tends to be relatively dense (compared to snowflakes, particularly dendrites) so accumulations are less than some snow types, and it certainly gives better traction than a glaze ice event from freezing rain, IMO.
It's rather interesting watching the wall-to-wall coverage of this nascent event on TV right now... KOCO 5, in my experience, tends to break in most often in any inclement weather situation, and today is no exception (they've been on for a while now). I do think they run out of things to say, since I've seen 3-4 minute stories about how to put a blanket on your windshield to mitigate the glaze icing, and some tips on how to properly scrape your windshield... *rolls eyes*. Oh well, I suppose I appreciate their coverage.
The QPF forecasts are still quite impressive, and there is a flooding threat across the ArkLaTex area with a couple bouts of >1.5" "waves" in the next 2 days. When the actual low/trough moves through, we'll see another substantial bout of precipitation (Sat night through Sunday evening), but I still think the biggest freezing rain potential lies along a Waurika to Eufala to Fort Smith line. If the QPF verifies, this could rival the Jan 2002 ice storm that crippled nw OK.
