27ºF and freezing rain in Salt Lake City. Radar: [link to ow.ly]

the skys have been clear for weeks, especially during the bitter cold...absolutly clear, not a cloud, not a trail in sight...

Here in Nevada

But Tuesday, the striping began and my husband said, "guess we'll be getting weather soon, they're striping."

boy was he right...clouds rolled in late yesterday, rained last night...everything thawing...

weather control, they brag about it all the time, what makes people think that it doesn't happen regularly...

Here comes the global warming.

...DISCUSSION...
LATEST SUITE OF MODEL GUIDANCE PRESENTS A BETTER GENERAL CONSENSUS
IN THE FORECAST EVOLUTION OF THE LARGE SCALE PATTERN ACROSS THE
CONUS INTO THE MIDDLE OF NEXT WEEK...ESPECIALLY WHEN COMPARED TO
THIS TIME YESTERDAY. WHILE THERE REMAIN DIFFERENCES IN THE
CONFIGURATIONS AND MAGNITUDES OF THE VARIOUS FLOW FIELDS AND
PARAMETERS...ANALYSIS OF THE GFS/ECMWF/UKMET/CMC/GFS ENSEMBLE AND
DPROG/DT LOOPS LEND SUFFICIENT SUPPORT FOR THE REINTRODUCTION OF A
SEVERE WEATHER FORECAST...NOW VALID FOR D4/TUESDAY...WITH A
CONTINUING THREAT INTO AT LEAST PART OF D5/WEDNESDAY.

AS INDICATED IN THE D3 OTLK...A WARM MOIST BOUNDARY LAYER IS
EXPECTED TO RESIDE ACROSS THE SCNTRL U.S. AHEAD OF A STRENGTHENING
LARGE SCALE TROUGH AND ASSOCIATED DEVELOPING COLD FRONT. WHILE ECMWF
CONTINUES TO FORECAST A SLIGHTLY SLOWER AND LESS FULLY-PHASED UPPER
TROUGH WHEN COMPARED WITH GFS/UKMET MODELS...EVEN IT COMES AROUND TO
FORECASTING AN AMPLIFIED AND SUBSTANTIALLY PHASED LARGE SCALE UPPER
TROUGH ACROSS THE SCNTRL AND ERN U.S. BEGINNING D4/TUESDAY AND
CONTINUING THROUGH D5/WEDNESDAY. THIS PROCESS WILL CONTRIBUTE TO A
RAPID ONSET OF DEEP-LAYER ASCENT AND SUBSEQUENT TSTM DEVELOPMENT
ALONG AND AHEAD OF A SHARPENING COLD FRONT THAT WILL SWEEP EWD/SEWD
ACROSS THE CNTRL/SRN PLAINS DURING THE DAY TUESDAY...AND THEN TO THE
TN VALLEY/NRN GULF COAST AND SOUTHEAST THROUGH WEDNESDAY. SHEAR AND
INSTABILITY AS CURRENTLY FORECAST WILL PROMOTE ORGANIZED STORMS IN
EITHER SUPERCELL OR LINEAR FORMS FROM NORTHEAST TX ACROSS THE
ARKLATEX TO SERN MO/WRN TN. SQUALL LINE OR LINE SEGMENT EVOLUTION
SHOULD BECOME MORE LIKELY WITH TIME AS COLD FRONT/CONVECTIVE COLD
POOLS FURTHER INTENSIFY AMIDST MODEST INSTABILITY. DAMAGING
WINDS...POSSIBLY WIDESPREAD...WILL BE THE GREATEST HAZARD WITH THIS
CONVECTION. HOWEVER...LOW LEVEL SHEAR WILL BE STRONG ENOUGH FOR
TORNADOES AS WELL.

EXPECT THE STRONG FORCING AND SHEAR TO MAINTAIN A QLSC WITH DAMAGING
WIND POTENTIAL AT LEAST INTO THE TN VALLEY THROUGH EARLY
WEDNESDAY/D5. BEYOND THIS TIME...GREATER MODEL SPREAD AND RESULTING
UNCERTAINTY BEGIN TO IMPACT FORECAST CONFIDENCE IN SEVERE WEATHER.
HAVE OPTED TO RELY ON GFS ENSEMBLE JOINT PROBABILITY FORECASTS FOR

THAT SEVERE WEATHER POTENTIAL WILL BE MUCH MORE UNCERTAIN WITH EWD

URGENT - WINTER WEATHER MESSAGE
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
416 AM EST SAT JAN 26 2013

...ICY ROADS AND AREAS OF DENSE FREEZING FOG ACROSS THE REGION
THIS MORNING...

.THE RECENT SLEET AND FREEZING RAIN ON AREA ROADWAYS IS COMBINING
WITH TEMPERATURES IN THE 20S AND LOWER 30S IN MANY LOCATIONS TO
PRODUCE BLACK ICE. IN ADDITION...AREAS OF FREEZING FOG ARE
DEVELOPING THIS MORNING. THIS MAY ALLOW A NEW GLAZE OF ICE TO
FORM ON ELEVATED SURFACES AS WELL AS SOME ROADS AND BRIDGES.
SLIPPERY CONDITIONS ARE LIKELY THROUGHOUT THE REGION FOR MUCH OF
THE MORNING HOURS...AND VISIBILITY MAY BE SEVERELY RESTRICTED.

421 AM CST SAT JAN 26 2013 /521 AM EST SAT JAN 26 2013/

...WINTER STORM WATCH IN EFFECT FROM SUNDAY MORNING THROUGH LATE
SUNDAY NIGHT FOR POTENTIAL OF SIGNIFICANT ICE ACCUMULATION...

THE NATIONAL WEATHER SERVICE IN CHICAGO HAS ISSUED A WINTER STORM
WATCH...WHICH IS IN EFFECT FROM SUNDAY MORNING THROUGH LATE
SUNDAY NIGHT.

* TIMING...FREEZING RAIN...POSSIBLY MIXED WITH SLEET...WILL
DEVELOP SUNDAY AND CONTINUE INTO SUNDAY NIGHT. FREEZING RAIN
WILL CHANGE TO RAIN SUNDAY NIGHT FROM SOUTH TO NORTH ACROSS THE
REGION AS TEMPERATURES GRADUALLY RISE ABOVE FREEZING.

* MAIN IMPACT...THE POTENTIAL EXISTS FOR SIGNIFICANT ICE
ACCUMULATION IN EXCESS OF A QUARTER OF AN INCH.

* OTHER IMPACTS...ICE ACCUMULATING ON TREE LIMBS AND POWER LINES
WILL WEIGH THEM DOWN AND WITH INCREASING WIND COULD RESULT IN
POWER OUTAGES. IN ADDITION...PAVEMENT AND SOIL TEMPERATURES ARE
BELOW FREEZING...SO ANY LIQUID PRECIPITATION WILL LIKELY FREEZE
ON CONTACT AND RESULT IN VERY ICY AND DANGEROUS TRAVEL
CONDITIONS ON UNTREATED ROADWAYS. SIDEWAYS AND WALKWAYS COULD
ALSO TURN TO SHEETS OF ICE MAKING EVEN WALKING DIFFICULT AND
POTENTIALLY DANGEROUS.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A WINTER STORM WATCH MEANS THERE IS A POTENTIAL FOR SIGNIFICANT
ICE ACCUMULATIONS THAT MAY IMPACT TRAVEL. THIS STORM IS STILL IN
THE DEVELOPING STAGES AND ANY MINOR CHANGES IN FORECAST
TEMPERATURES COULD RESULT IN SIGNIFICANT CHANGES TO THE FORECASTED
PRECIPITATION TYPE AND RESULTANT ICING THREAT. CONTINUE TO MONITOR
THE LATEST FORECASTS AND STATEMENTS ON THIS DEVELOPING WINTER
STORM.

Friday, January 25, 2013January 27 Severe Ice Storm
By Andrew at 10:24 PM

A severe ice storm appears to be attempting to set up across the Midwest, Great Lakes and Ohio Valley.

As a storm system begins to approach the region shown above, temperatures will warm to near freezing levels, a perfect scenario for an ice storm. Now, freezing rain is a very tricky precipitation type that commonly comes down to a 'nowcasting' (forecasting as it happens) event, because the environment that supports freezing rain (called ZR in the weather world) is so hard to achieve.

However, recent model forecasts have been in general agreement that an ice storm will hit come Sunday afternoon into evening for the areas in dark purple. These areas could see a severe ice storm with significant travel impacts, as shown below in the Exclusive Impact Scale. I am seeing one forecast for nearly half an inch, one forecast around a quarter of an inch, and another forecast around .15'' in the dark purple areas, so I decided to go to the medium and forecast a fifth of an inch to 4/10th's of an inch, with that plus sign added in the event that half inch forecast verifies. Considering it's an outlier, I'm not that optimistic on amounts really exceeding 0.4''.

Areas in light purple will experience lighter ice accumulations, but still with substantial travel impacts. I expect the Midwest to get the higher end of this 0'' - 0.2'' forecast, with the Ohio Valley getting around the median. But again, it will likely be a nowcasting event.

Polar Vortex Takes Another Swing at Northern US
By Andrew at 5:58 PM

The latest GFS model forecast has the polar vortex taking another swing at the Northern US in the next 5-7 days, as January begins to wrap up.

As I have been fearing, the multiple sudden stratospheric warmings are taking their toll on the polar vortex here at the surface. We already had the initial impact of the split polar vortex over Martin Luther King Jr. Day, and now appear to be looking at Round 2. As the 500mb forecast above details, there could be a second, stronger blast of cold air that hits the northern part of the nation. The GFS places this piece of the vortex substantially further south than the previous brush with the vortex; that one went into South Canada.

It does not matter where this piece of the vortex goes, because the ball has already been rolling on what we could face in February. I have been seeing consistent forecasts that detail a full stratospheric polar vortex breakdown, more on that later tonight.
