Snow in the forecast (or not)

Posted Monday, November 30, 2009, at 10:20 AM

Update Dec. 2: It now looks like this is going to be an all-rain system. We'll have to wait some more before we see "Winter Storm Akira."


The latest forecast from the National Weather Service now includes the "S" word for Wednesday afternoon and night.

WEDNESDAY... RAIN LIKELY IN THE MORNING THEN RAIN OR SNOW LIKELY IN THE AFTERNOON. HIGHS IN THE UPPER 40S. TEMPERATURE FALLING INTO THE UPPER 30S IN THE AFTERNOON. NORTH WINDS 10 TO 15 MPH. CHANCE OF PRECIPITATION 70 PERCENT.

WEDNESDAY NIGHT... SNOW AND RAIN LIKELY. LOWS IN THE LOWER 30S. CHANCE OF PRECIPITATION 60 PERCENT.

The forecasters are hedging their bets, explaining in this morning's technical discussion:

THE THINKING IS RIGHT NOW THAT EVEN IF WE GET A FEW HOURS OF DECENT SNOWFALL... ANY IMPACTS WOULD BE MINOR TO NON EXISTENT DUE TO THE RELATIVELY WARM GROUND AND SFC TEMPS REMAINING ABOVE FREEZING. MAIN THING WOULD BE THAT IT COULD BE THE FIRST SNOW IN THE AIR THIS SEASON... AND EVEN THAT IS NOT CERTAIN AT THIS TIME.

With temperatures expected to reach the upper 40s Wednesday morning, the ground will certainly be too warm for the snow to stick, even as temperatures drop to freezing by Wednesday night. These rain-changing-to-snow scenarios typically don't pan out. Still, the odds look favorable for at least some white stuff this week.

Nah, won't stick if it does---but that's a GOOD-thing!

It'd be a "fun"-snow, one that you can laugh at and enjoy, instead of, say, six-weeks from now, when you'd be fuming and dreading, on the way to work and back...!
