Update: Tornado Watch Issued

Tornado Watch

Until 8:00 PM EST on January 30, 2013

http://wxug.us/knc0

For the Nerds Out There:

MESOSCALE DISCUSSION......WRN CAROLINAS...
STRONGEST HIGH-LEVEL DIFLUENCE...DOWNSTREAM OF THE AMPLIFIED UPPER
TROUGH TAKING ON A MORE NEUTRAL TO NEGATIVE TILT AS IT SHIFTS INTO
THE LOWER MISSISSIPPI VALLEY...APPEARS LIKELY TO GRADUALLY BEGIN
SHIFTING NORTHEASTWARD...TO THE EAST OF THE SOUTHERN APPALACHIANS
...THROUGH 20-22Z. THIS FORCING IS EXPECTED TO BE ACCOMPANIED BY
THE NORTHERN FLANK OF THE MORE VIGOROUS PORTION OF THE ONGOING
PRE-FRONTAL SQUALL LINE...WHICH COULD STILL INCREASE IN INTENSITY AS
THE BOUNDARY LAYER CONTINUES TO DESTABILIZE TO THE SOUTH AND EAST OF
THE SMOKY/BLUE RIDGE MOUNTAINS. WHILE THE MAGNITUDE OF
DESTABILIZATION COULD STILL BE SOMEWHAT MARGINAL...STRENGTHENING OF
SOUTHWESTERLY LOWER/MID TROPOSPHERIC MEAN WIND FIELDS IN EXCESS OF
60 KTS WILL CONTRIBUTE TO THE RISK FOR DAMAGING SURFACE GUSTS WITH
THE SQUALL LINE. IT ALSO DOES NOT APPEAR OUT OF THE QUESTION THAT
DISCRETE SUPERCELLS COULD DEVELOP AHEAD OF THE LINE...WITH A MORE
SUBSTANTIVE RISK FOR TORNADOES...IN THE PRESENCE OF STRONG TO
EXTREME NEAR SURFACE SHEAR.

Hail No But Winds Yes

Not the usual type of winter storm to affect us (will see the effect later) this afternoon as a squall line of showers and embedded thunderstorms will push through the area late this afternoon. Expect at least a thunderstorm watch going into effect soon, possibly tornado watch as conditions are slightly favorable for tornadic activity later. Already a wind advisory in effect, and if you've been outside lately you'll know why - it's windy... Hope everyone picked up things that blow away in strong winds, including small children.

 Here's s look at current watches and outlooks issued by the Storm Predicition Center (SPC). I have a link to it on the right which you can check later to see what's going on.

MAIN THREAT = WIND

TORNADOES POSSIBLE

WWA'S (WATCHES, WARNINGS, ADVISORIES) IN EFFECT AT 12:30PM (EST)


STORM REPORTS SO FAR SHOWING LOTS OF WIND DAMAGE TO OUR WEST



RADAR: ACTIVITY STILL WEST OF THE MOUNTAINS WITH SHOWERS MOVING THROUGH BEFORE MAIN AREA ARRIVES AROUND 4-5PM 


LAST, BUT NOT LEAST, LATEST SPECIAL WEATHER STATEMENT FROM THE NWS WITH EMPHASIS ADDED:

A STRONG COLD FRONT WILL SWEEP EAST ACROSS NORTHEAST GEORGIA AND
THE WESTERN CAROLINAS THIS AFTERNOON THROUGH THIS EVENING. A LINE
OR BAND OF STRONG TO SEVERE THUNDERSTORMS AHEAD OF THE COLD FRONT
WILL MOVE ACROSS THE REGION WITH THE POTENTIAL TO PRODUCE
WIDESPREAD WIND DAMAGE WITH SOME WIND GUSTS IN THE 50 TO 70 MPH
RANGE. IN ADDITION...THERE IS THE POTENTIAL FOR A FEW BRIEF
TORNADOES TO DEVELOP. SOME OF THE SEVERE STORMS WILL OCCUR WITH
LITTLE OR NO LIGHTNING. ISOLATED FLOODING COULD DEVELOP ALONG A
FEW STREAMS BY LATE IN THE DAY. THE LINE OF STORMS SHOULD CROSS
THE MOUNTAINS THROUGH THE EARLY AFTERNOON. THE LINE WILL THEN MOVE
OUT ACROSS UPSTATE SOUTH CAROLINA AND THE NORTH CAROLINA FOOTHILLS
IN THE EARLY TO MIDDLE PART OF THE AFTERNOON...AND THEN THE
WESTERN PIEDMONT OF NORTH CAROLINA IN THE LATE AFTERNOON AND EARLY
EVENING.

Friday Snow = Weak, Slick Sauce

With a resurgence of cold and dry high pressure (especially relative to normal) building into the region today - current wind says it all - tomorrow's winter wx event is looking less and less likely to be much of an "event".

What to expect: Snow Showers beginning around noon, with total accumulation by sunset around 1", with sleet and freezing rain mixing in towards evening. Total QPF (precip) is going to be slim, maybe .15" on the optimistic side.

This means if most falls as snow 1" is definitely possible (10:1 ratio) but if sleet or freezing rain predominates that will negate snowfall, and more importantly create a nuisance as far as travel/roads are concerned.

To recap: expect approx 1" of snow to fall with sleet/freezing rain at the end to put an icy glaze on top. However, with temperatures staying at or below freezing, although a minor event, expect it to impact the end of your workday and make for a slick commute home.

Will The CAD Be Bad?

Cold Air Damming (CAD) winter weather event is the headline for Friday. I expect the NWS will issue watches or advisories for the area by morning. Here in the greater Salisbury Metro, it looks like we will see a combination of snow to sleet to freezing rain on FRIDAY - beginning around noon - and ending around sunset.

Exact precip amounts are still the tricky part and will determine how much of an impact the slippery slop will have. Suffice it to say the weather will not be pretty and with temperatures below freezing expected even at warmest period of the day, all that falls should be frozen or will freeze on contact.

Expect a short day and a slippery way...home. More details tomorrow. Out for now.

Eyes on Friday

I won't be verbose because the details are not discernible yet but I fully expect wintry weather on Friday possibly into Saturday AM. Most likely not a big event because the storm system will not be very moist, but could surprise folks, especially if it turns icy. Regardless of any storm, the coldest air of the season is here and will stick around. Should see lows bottom out around 14° later this week so make sure your pipes don't freeze (self...).

Stay tuned. Out Here.

Winter - On Our Doorstep

Rest assured, everything looks on track for snowfall. Low Pressure (occlusion actually) has just passed to our south and east along the border near Charlotte.

Easy way to tell: barometric pressure and dropping dew-point - this from my wx station recently:


Water Vapor Image


Still expecting the 8:36 PM switch, so 2 hours approx.

Rain should ease up for a bit and then begin again heavily and the harder it falls the sooner we switch over as cold air is drawn down into the lower levels more rapidly. Thunder-snow not out of the question honestly.

Snowing in Boone and Jefferson (around 3500') and the line between rain and snow should move eastward rather quickly as banding precip sets up. If you look at radar now and say it's all gone, just wait.

Sounds Of Silence

Not much to add to my initial thoughts yesterday. Still expect an average 4" of snow by tomorrow morning here in the Salisbury - Rowan Megalopolis.

Also noticed the National Weather Service guys read my blog - Winter Storm Warning in effect starting late afternoon/tonight. Wannabes.

Main impact/question will be amount of accumulation on roads - school / work / etc. It will be no bueno on the roads for school buses but the rest of you (us) will probably have to wait and see. However, the Rowan County Courthouse will always be open so no worries there...

On a positive note, the Blanton Law Firm is always open to help you if we can. If, for example you:

T-Bone someone's car while doing a mean 5mph (because you can't drive when the roads are dry) - Call from your cell because you were probably on it anyways.

Commit a criminal act because you are at home with your spouse and/or children for 4 days straight. Call from jail.

You act and/or are a juvenile and throw snowballs at someone and they commence to seeing just how big a boy you are... Call from the hospital.

Obviously I hope none of this occurs, but I'll throw that in there because I might be a little late to work because I'm still looking at weather so got to run.

Again, the BLF's # is 704-637-1100. *Only for legal matters not for personal forecasts.

Hope you all enjoy. Will try and update if need be this afternoon.

expected. Black ice late at night.

* Temperatures... falling through the 30s late in the day.

* Winds... north 10 to 20 mph with gusts up to 30 mph.

Precautionary/preparedness actions...

Thump In The Night - Snow Forecast

I'll be brief. Yes, think it will snow overnight Thursday into Friday.

Why: Upper level low passes to our SE and deformation zone forms over western NC

Read: Snow falls heavily but quickly. Probably a 4-5 hour event & you'll be asleep.


Low Track

Forecast Snowfall Accumulation: 4" (Rowan County)


There you have your thump in the night. I'll post later for the nerdy crowd/myself.

P.S. Do your homework for Friday anyways

70°, You Said You Would Write...

Dear 70°,
 It feels like you left a month ago already. Apparently it has only been 24 hours. Still, no cards? No worries here. I'm over you already. I've moved on (sound familiar???). This probably doesn't surprise you because of the obvious lies you told me about sticking around for a while.
  Oh, My Dr. says that the extra therapy is NOT related at all to you - preexisting condition (shout-out to my man B.O in Washington!!!). Anyways, that's all I have to say. You have my cell, so if you're around this spring I probably won't answer...
  Gotta go see the new guy in town. He's supposed to be even cooler than the other side of the pillow. So, like, whatever. Later.
