Yeah I was surprised he went "light" and "not amounting to much." Almost every system has been juiced, even weak lows. 2-3 inches is a BIG deal. Maybe he is referencing the backside changeover.......which for many would be light.

I have been telling friends for days I thought that would be a good snow, but my gut was telling me for Kentucky and the OH Valley.

Trends for the last couple of systems has been further south and east. Makes me wonder about the one late weekend. THAT air mass is so much colder & heavier than the one for the next couple of days (which isn't anything to sneeze at)

You know you are grasping at straws when you are looking at the 84 hour NAM. With that said, it has light to moderate precip breaking out in west TN with cold enough 850's, and temps in the mid 30s. This run would likely do well for west and central TN, and especially parts of KY. (if extrapolated)

It looks like the PV is further south too with the NAM. If we had that and snow cover on the ground we would have a better chance of going below zero which I know you wouldn't like lol

0z GFS...Sun/Mon Very strong frontal passage w/ .5-.75 qpf. Looks like the cold air catches the moisture. Notice at 102 that energy rotating under the base...it swings up and catches the front ...would phase if one sped up or the other slowed down. Eventually, it gets pulled in anyway. Really close to a significant event IMO.

Yeah that was a good run for the E Valley

I believe we need a thread for the Sun/Mon event.

 

Looking over the 0z Euro text, it seems to agree with 0z/6z GFS idea of 2 to 3 inches of snow across much of TN.

 

Probably wouldn't hurt.  Especially if 12z suites come in any further SE with the track.  #fingerscrossed

Excerpt drom MRX this evening regarding Sunday through Thursday next week...Excellent write-up.

 

Begin Quote..........

 

.LONG TERM (FRIDAY NIGHT THROUGH THURSDAY)...
AT THE BEGINNING OF THIS PERIOD WE ARE SQUARELY BETWEEN TWO
SYSTEMS...THE WINTER STORM FROM THURSDAY NIGHT AND THE NEXT SYSTEM
DUE IN ON SUNDAY. AFTER THE ONE ON SUNDAY...WE GO INTO THE DEEP
FREEZE FOR A COUPLE OF DAYS...THEN A QUICK CLIPPER TYPE SHORTWAVE
COMES RACING INTO THE AREA TOWARD THE END OF THE FORECAST.

THE FORECAST LOOKS DRY FOR SATURDAY AND SATURDAY NIGHT...THEN RAINS
MOVE INTO THE AREA ON SUNDAY. THE MOISTURE FOR THIS FRONTAL PASSAGE
ON SUNDAY IS PRETTY PAWLTRY...SO NOT EXPECTING STORMS AHEAD OF THIS
FRONT. FOR THE RAIN/SNOW ON SUNDAY...IT IS THE PATTERN MUCH LIKE
TODAY WITH COLDER AIR COMING INTO THE REGION AND CHANGING THE RAIN
TO SNOW...WEST TO EAST. THE ONE DIFFERENCE IS THAT THIS SNOW WILL
LINGER AROUND LONGER--THE DENDRITIC GROWTH TEMPERATURES WILL BE
COMING VERY LOW IN THE TROPOSPHERE WITH LOW LEVEL MOISTURE LOOKING
TO BE ENOUGH TO GET SOME SNOW SHOWERS GENERATED. THIS ISN`T DEEP
ENOUGH TO GET ANY SIGNIFICANT CAPE IN THE MODELS...BUT IT LOOKS LIKE
THE SLIGHTEST LIFT WILL BE ABLE TO GENERATE SOME LIGHT SNOW
SHOWERS. THIS ALSO WILL SET THE STAGE FOR A LONG DURATION UPSLOPE
EVENT FOR THE EASTERN MOUNTAINS FROM SUNDAY NIGHT THROUGH MONDAY AND
MONDAY NIGHT--NOT THE CLASSIC SETUP WITH THE MOISTURE RELATIVELY
SHALLOW...BUT WITH THE DENTRITIC GROWTH ZONE SO LOW...IT SHOULD
ACCUMULATE STEADILY OVER THIS PERIOD. WILL WATCH FURTHER MODEL RUNS
TO SEE IF THIS PATTERN HOLDS.

THEN THE CONCERN TURNS TO THE EXTRMELY COLD TEMPERATURES. LOOKS
LIKE IT WILL BE BELOW FREEZING OVER MUCH OF THE AREA FROM SUNDAY
NIGHT UNTIL WEDNESDAY AFTERNOON--60+ HOURS BELOW FREEZING. THE
CLIPPER SYSTEM THAT IS DUE IN BY THE END OF THIS FORECAST WILL
DEPEND HEAVILY ON ITS TIMING...IF IT IS FAST...THERE WILL BE A
BETTER CHANCE OF WINTRY PRECIPITATION...SLOWER WILL MEAN RAIN OR
POSSIBLY SOME FREEZING RAIN. THIS SYSTEM DOES NOT LOOK OVERLY
STRONG AT THIS POINT.

I really think the temps at all levels will be crashing hard enough to see great ratios.......so much so that it will use the .05-.10 that falls as snow and turn it into 1-2 inches of fluffy snow for valley locations. The mountains will have another blizzard situation on their hands with 6-8 inches of fluff from upslope.

Was reading where some Met in Ky said about Sun event "This is not going to be a deep area of low pressure and these waves often end up flatter than forecast because the models tend to underplay the eastward push of arctic air behind them"..went on and said maybe 2 inches on the backside of the front..Really don't understand that statement but I'm no met either..lol..Anyway's hope today's runs keep trending south and become's stronger..
