One thing seems in agreement at this point. March is looking cooler than normal. Just a kick in the jewels after another crappy winter.

seems to happen a lot in NINA winters

nonetheless, a beautiful day and the sun feels real warm

that said, I wouldn't be surprised at all if something becomes at least "threatening" to us over the next 7-10 days

this usually happens in Ninos, but I figure to add insult to injury something will cut off in dixie in late March or Early April. Atlanta will get 3" of daytime paste on like March 26th and the Smokies will get 16-24"

but since this is more of a NINA than anything else, it'll trend north, though not necessarily far enough or possibly too far given this year

For those west of the BR, Tuesday could be messy. Certainly would also appear that it's not an outcome that's set in stone as to type.

From LWX:

1...TIMING. THE TREND OF THE SREF OVER THE LAST 24 HRS HAS

BEEN TO SLOW DOWN PRECIP ONSET ACROSS OUR CWA. THIS IS BACKED UP

BY THE LATEST RUNS OF THE NAM AND GFS...AND QUICK PEEK AT LATEST

12Z ECMWF ALL SUPPORT THIS SLOWING OF PRECIP ONSET. EXPECT

MEASUREABLE PRECIP TO HOLD OFF MAINLY AFTER 12Z...EXCEPT UP TO CHC

POPS IN THE FAR SW ZNS AFTER 09Z. THE 09Z SREF/12Z GFS/ECMWF SOLUTIONS

ARE ALL PRETTY CLOSE IN DEPICTING A BAND OF PRECIP OVERSPREADING

THE AREA DURING THE MORNING HOURS...AND BY AFTERNOON HAVE DEFINITE

POPS CWA WIDE.

2...WINTER P-TYPE AND AREAL EXTENT.

18Z NAM CONTS TO DEPICT A SGFNT PD OF FZRA FOR THE PTMC

HIGHLANDS...WHILE THE 18Z GFS BUFR DATA PAINTS IT AS MOSTLY SNOW.

ECMWF TKNS SCHEMES SUGGEST A MELTING LYR BUT COLD LLVLS TO

START...WARMING EVERYTHING DURING THE AFTN.

GIVEN THE STRONG WAA OCCURRING THROUGHOUT THE SOUNDING...WOULD

EXPECT A WINTRY MIX...WITH SNOW/SLEET EXPECTED EARLY IN THE

MORNING IN AREAS MAINLY WEST OF THE BLUE RIDGE...AND TRANSITION TO

MORE SLEET AND/OR FREEZING RAIN AS THE MORNING PROGRESSES. FOR THE

DC BALTIMORE METRO AREAS...A BRIEF PERIOD OF SLEET/SNOW AT ONSET...

BUT WOULD QUICKLY TRANSITION TO ALL RAIN.

3...QPF LIQUID AMOUNTS. PROGS SUGGEST A RANGE BETWEEN ONE HALF TO

NEAR ONE INCH CWA-WIDE. 12Z GFS IS MORE PROGRESSIVE WITH THE

SYSTEM AND SUGGESTS ABOUT A 5-7 HOUR PERIOD OF MODERATE QPF WITH

THE PASSAGE OF A SINGLE FRONTEGENTICAL FORCED BAND. 12Z NAM IS

SLOWER FOR QPF TO DEPART AND KEEPS SOME QPF THROUGH 06Z WED.

ALTHO THERE ARE STILL ISSUES TO BE RESOLVED...THERE IS ENOUGH

EVIDENCE THAT THERE IS THE POTENTIAL FOR MESSY CONDS IN THE PTMC

HIGHLANDS...SPCLY TUE MRNG. HV ISSUED A WINTER STORM WATCH FOR

THESE CNTYS. WHILE THE TRIGGER ATTM WUD BE ICE ACCUM...KEPT RATHER

GENERIC WORDING IN CASE LATER SOLNS LEAN MORE TWD GFS /IE...SNW-

SLEET/. WL BE MONITORING LATER GDNC IN CASE THE WATCH NEEDS TO BE

EXPANDED EWD.

Any severe weather on the horizon?

 

Winter 2012 - 2013 - WAS NOT ROCKIN' ..... It was STINKIN'

 

I see one last chance that it could pull a rabbit out of it's hat, but it probably would be rain or so light we should forget about it!

That's just it - it's going to be too cold and too dry for any severe weather.  March is looking nasty cold.  Persistent cold.

 

Also... March 1 average high is 51 degrees.  March 15 average is 56 degrees.  March 31 average is 61 degrees.  So the term "cold" means something very different in March to what it means in January or February.

don't fret Randy, it happens every year

it's called March 1....winter really is over

not that this model's prediction will be right, this link is the main factor that us snow lovers should be looking to for next year

Given our luck it will probably rise a bit and then right on schedule follow the lowest possible forecast on that chart :(
