Surprisingly, every once in a while something funny comes across the weather wire. And instead of storing these things on my personal computer, I figured I would share the following with the blogger community (whomever you are!).
First up, a much too detailed Area Forecast Discussion from the Duluth, MN NWSFO on the morning of November 6th:
We had a pretty good laugh about it at work. Not only because it is the most detailed and technical discussion any of us had seen for a lake-effect event, but also because some of this, we had no clue what to make of. Personally, my favorite part was the mention of the "seemingly immortal showers." That's just funny.LAKE EFFECT SHOWERS MAY TAKE THEIR TIME IN MOISTENING THE
LOWER PARTS OF THE COLUMN...BUT ONCE THAT COLUMN IS
MOISTENED...THE SHOWERS PERSIST EVEN AS MODELS TRY TO
INFILTRATE DRY AIR AND END THEM. MORE IMPORTANT THAN
MOISTURE...ANGULAR MOMENTUM IS CONSERVATIVE. IT TAKES
QUITE A BIT OF ENERGY TO START AIR ROTATING ALONG AXES OF
STREAMWISE HORIZANTAL VORTICITY. BUT ONCE THAT ENERGY HAS
BEEN INVESTED...THE ROTATING HORIZONTAL TUBES OF
HORIZONTAL VORTICITY WILL MAINTAIN SHOWERS IN THEIR UPWARD
MOTION AREAS. EVEN WHEN AN INVERSION LOWERS...THE SHOWERS
CONTINUE BECAUSE THE INVERSION SEEMS TO BE PUSHED ALOFT
MANY MANY METERS OVER THE UPWARD MOTION AREAS...
MAINTAINING ENOUGH DEPTH FOR SUBSTANTIAL SNOW PRODUCTION
FROM EXISTING SHOWERS. WE HAVE FOUND THAT ONCE LAKE
CONVECTION HAS BECOME ESTABLISHED...WARM ADVECTION AND AN
ACCOMPANYING WIND SHIFT AT ALL LEVELS HAS TO PHYSICALLY
PUSH THE SEEMINGLY IMMORTAL SHOWERS OFF THE SHORE WHERE
THEIR EXISTANCE OR NON-EXISTANCE IS NO LONGER OUR PROBLEM.
WE ANCPT COLD ADVECTION UNTIL ABOUT 10Z WEDNESDAY ACROSS
THE GOGEBIC RANGE. SO WE ARE TEMPORIZING BY EXTENDING THE
WINTER STORM WARNING UNTIL 06Z WEDNESDAY.
THERE IS ANOTHER POINT BEARING UPON OUR REASON OF EXTENDING
THE WINTER STORM WARNING WESTWARD ACROSS ASHLAND COUNTY.
BESIDES REPORTS OF SEVEN INCHES OF FRESH SNOW AND VERY
HEAVY SNOWFALL RATES SOUTH OF ASHLAND...RADAR SHOWS A
STANDING WAVE DEVELOPING EAST OF THE MOUNTAINS THAT RUN
DOWN ALONG THE SPINE OF THE BAYFIELD PENINSULA. SATELLITE
IMAGERY CONCURS WITH THIS OBSERVATION. THE STANDING WAVE IS
PROPAGATING TO THE SOUTHWEST...SOUTH OF THE BAYFIELD
PENINSULA. SUBSTANTIAL MOISTURE HAS BECOME ENTRAINED INTO
THIS PROPAGATING WAVE INTO AN UNSTABLE ENVIRONMENT. THAT
PROPAGATING CONVECTION IS THE SOURCE OF THE SNOWFALL REPORTS
IN ASHLAND COUNTY...WELL SOUTH OF THE LAKESHORE. WITH LITTLE
CHANGE IN COLUMN STRUCTURE...THERE IS NO REASON TO BELIEVE
HAT THE STANDING WAVE WILL FALL APART ANYTIME SOON. OUR
COMMENTS ABOUT ANGULAR MOMENTUM BEING CONSERVATIVE ALSO
APPLY TO THE EXPECTED CONTINUED EXISTANCE OF THIS STANDING
WAVE.
Secondly, a rather humorous (obviously edited!) forecast map:
A friend of mine had this in his Facebook profile. Drizzle, that makes sense, but the rest? Quite the laugh!
