... Winter weather awareness in the mid south...
November 17th through 21st is winter weather awareness week in
the mid south. People are asked to take some time and prepare for the
upcoming winter season.
Todays topic is winter precipitation types.
Snow -- snow forms in the clouds and remains as snow all the way to
the ground. It most commonly takes the form of snowflakes... which
are the familiar six-sided ice crystals. It may also fall in the
form of snow pellets or snow grains.
Snow flurries are most commonly seen as a few snowflakes falling...
although visibilities can be reduced at times. In the mid south... the
term snow flurries is used to indicate that no accumulation is
expected.
Snow showers is a term not often used in the mid south. In this type
of precipitation... the snow falls at varying intensities over brief
periods of time. Accumulation may occur... especially during moderate
to heavy snow showers.
Blowing snow most commonly refers to snow that is already on the
ground and is lifted into the air by the wind.
In the mid south... heavier snows most commonly occur when cold air is
already in place over the region and a strong upper level low
pressure system moves out of the southwestern United States. The low
serves to pull moist air northward into the cold air. Light snow or
snow flurries can also occur in the cold air that follows the passage
of an Arctic cold front.
Sleet - sleet consists of pellets of ice. In fact... for people who
have trouble with the difference between sleet and freezing rain...
it may be easier to associate sleet with its technical name... which
is ice pellets. For sleet to form... snow begins falling from the
clouds but then GOES through a layer of above-freezing air thousands
of feet above the ground. This causes the snow to change to rain.
Then... the rain GOES through a layer of below-freezing air... usually
at least two to three thousand feet thick... and the precipitation
turns into pellets of ice.
Sleet typically occurs in a fairly narrow band. This band usually
moves... but at times may remain nearly stationary... resulting in
accumulations of sleet.
In the mid south... sleet most commonly occurs in a narrow band
between an area of rain to the south and an area of snow to the
north.
Freezing rain -- this weather phenomenon is sometimes called glaze...
because of the glaze of ice it puts on surfaces at the ground.
Freezing rain most commonly occurs when precipitation falls from the
clouds as snow... then GOES through an above-freezing layer... which
turns the precipitation to rain. Then... the rain reaches the ground
where temperatures are below freezing. The rain then freezes as it
hits exposed objects. In the worst cases... everything becomes coated
with a layer of ice.
In the mid south... freezing rain commonly occurs as an Arctic high
pressure system begins to move away from the state. In this
situation... cold air is still lingering at the ground... but warmer
southerly winds from the Gulf of Mexico begin bringing moisture back
over the top of the cold air. Since the air at the ground has not
warmed above freezing... the rain that falls freezes on the ground and
other objects. Freezing rain... and its cousin freezing drizzle...
often develop during the late night hours... creating icy conditions
for morning rush hour.
Freezing fog -- while this is not precipitation falling from the
clouds... it is another winter weather hazard. Freezing fog typically
develops on clear... calm nights when temperatures are below freezing.
Fog forms and freezes... usually on bridges... overpasses... and other
elevated roadways. It can create quite a surprise for motorists... due
to the presence of clear skies overhead.
Frost -- frost describes the formation of thin ice crystals on the
ground or other surfaces in the form of scales... Needles...
feathers... or fans. Frost forms when water vapor in the air turns
directly to ice crystals on an object. The temperature of the object
must be below freezing for frost to occur. However... frost is
sometimes seen on the ground when official temperatures are reported
to be above freezing. This is because the official temperature is
taken about five feet above the ground... where the air can be a few
degrees warmer than the temperature at ground level.

NWS Forecaster Discussion
765 fxus64 kmeg 201141 aaa afdmeg Area forecast discussion...updated National Weather Service Memphis Tennessee 541 am CST Thursday Nov 20 2008 Update... updated for aviation. && Discussion... /issued 443 am CST Thursday Nov 20 2008/ Discussion...10z surface analysis places a cold front from the Ohio Valley back through middle/west Tennessee and the northern half of Arkansas. Temperatures across the middle south as of forecast issuance are primarily in the 30s under clear skies and winds nearly calm. Challenges in the short term forecast are cloud cover/temperatures and precipitation chances in the long term forecast. Short term...(today through saturday)...a dry Canadian cold front will continue to move through the middle south this morning bringing a return of much colder air back to the middle south today. 11-3.9 micron satellite trends/metar observations as of 10z show the leading edge of a stratus layer stretching from Indianapolis back through Farmington and Springfield Missouri which has been drifting south southeast during the overnight hours. Short term soundings indicate low level moisture in 950-900 mb layer trapped below a strong subsidence inversion will produce mostly cloudy to partly sunny skies along and north of the Tennessee/Mississippi State today. Highs today will range from the 40s north of I-40 and lower to middle 50s across north Mississippi. Low level clouds will depart the forecast area this evening leading to clear skies and temperatures dropping back into the 20s in most locations. Cold Canadian high pressure will keep high temperatures Friday well below normal with readings in the 40s. Temperatures will gradually begin to moderate during the day Saturday as high pressure moves east and southerly winds return to the lower Mississippi Valley. Long term...(sunday through wednesday)...long range models in decent agreement this morning as an upper level trough moves from the northern plains into the eastern United States by the end of the period. Have raised probability of precipitation up to 50 percent for portions of the area Sunday night and the entire area Monday as both 00z European model (ecmwf)/GFS indicate frontal passage around 12z Monday. High pressure will build into the middle south Monday night with rain chances coming to and end across northeast Mississippi Monday evening. Cjc && Aviation... 12z taf cycle 11z surface map showed a cold front entering northeast Arkansas/MO bootheel...with a prefrontal trough oriented roughly along Interstate 40 through kmem. Strongest northerly surface winds were occurring behind the cold front...with 20 knots gusts noted over southeast MO. MVFR ceilings were noted over MO and southern Illinois...though the southward progression of the low stratus had slowed somewhat over the past hour. This low stratus remains the primary forecast concern. GFS lamp guidance keeps all midsouth terminals VFR today...but GOES infrared loops suggest MVFR ceilings into kjbr a good bet and at least periodically over kmem late this morning.
