Sleet, Freezing Rain Potential Tonight

527 AM CST SUN DEC 6 2009

…RAIN MAY MIX WITH OR CHANGE TO SLEET AND FREEZING RAIN LATE
THIS EVENING OR OVERNIGHT…

PRECIPITATION WILL DEVELOP THIS EVENING AND CONTINUE OVERNIGHT AS
LOW PRESSURE PUSHES THROUGH THE MID MISSISSIPPI RIVER VALLEY. THE
PRECIPITATION SHOULD BEGIN AS LIGHT RAIN ACROSS THE MIDSOUTH…BUT
MAY MIX WITH OR CHANGE TO FREEZING RAIN AND SLEET IN THE LATE
EVENING AND OVERNIGHT AS THE RAIN FALLS INTO COOLING AIR AT THE
SURFACE. THE EARLIEST SURFACE TEMPERATURES WOULD APPROACH
FREEZING WOULD BE AROUND 9 PM.

LOCATIONS ALONG AND NORTH OF INTERSTATE 40 STAND THE BEST CHANCE
OF SEEING THIS CHANGE OVER OCCUR…BUT IT MAY OCCUR AS FAR SOUTH
AS THE TENNESSEE/MISSISSIPPI STATE LINE IF THE EVAPORATIVE COOLING
IS STRONG ENOUGH. ANY FREEZING RAIN OR SLEET SHOULD CHANGE BACK TO
RAIN BY THE MONDAY MORNING RUSH.

IF THE CHANGE OVER DOES OCCUR TONIGHT…ICE ACCUMULATIONS SHOULD
BE LESS THAN A FEW HUNDREDTHS OF AN INCH WITH SLEET ACCUMULATIONS
LESS THAN A TENTH OF AN INCH. HOWEVER…THIS MAY STILL PRODUCE
SLIPPERY SPOTS ON ROADWAYS…ESPECIALLY ON BRIDGES AND OVERPASSES.

STAY TUNED TO NOAA WEATHER RADIO OR YOUR FAVORITE MEDIA OUTLET FOR
ADDITIONAL DETAILS AND THE POSSIBLE ISSUANCE OF A WINTER WEATHER
ADVISORY LATER TODAY.

A Taste of Winter Rides in with December

(Sunday, November 29, 2009) – The first round of wintry weather could affect West TN this week.  Models are in agreement that we will be heading into a weather pattern that will offer colder air coming into the region the last half of the week.

Right now it appears a low pressure will form near the LA coast Wednesday morning and track through Columbus, MS on Wednesday Evening to West Virginia on Thursday morning.

Rain is expected to make a return to West TN on Tuesday night or Wednesday.  Cold air will pour into the area behind the low pressure that will be passing to our east and that could cause a wintry mix, mainly north of I-40.  No travel difficulties are expected where any wintry weather is experienced as the moisture is expected to be leaving quickly out of the area and ground temperatures are still in the 40s.

Additional posts will be made as needed.

Winter Awareness Week

NOAA’S NATIONAL WEATHER SERVICE SAYS:
KNOW YOUR WINTER WEATHER TERMS

NOAA’s National Weather Service urges residents to keep abreast of local forecasts and warnings and familiarize themselves with key weather terminology.

Winter Storm Warning: Issued when hazardous winter weather in the form of heavy snow, heavy freezing rain, or heavy sleet is imminent or occurring. Winter Storm Warnings are usually issued 12 to 24 hours before the event is expected to begin.

Winter Storm Watch: Alerts the public to the possibility of a blizzard, heavy snow, heavy freezing rain, or heavy sleet. Winter Storm Watches are usually issued 12 to 48 hours before the beginning of a Winter Storm.

Winter Storm Outlook: Issued prior to a Winter Storm Watch. The Outlook is given when forecasters believe winter storm conditions are possible and are usually issued 3 to 5 days in advance of a winter storm.

Blizzard Warning: Issued for sustained or gusty winds of 35 mph or more, and falling or blowing snow creating visibilities at or below ¼ mile; these conditions should persist for at least three hours.

Lake Effect Snow Warning: Issued when heavy lake effect snow is imminent or occurring.

Lake Effect Snow Advisory: Issued when accumulation of lake effect snow will cause significant inconvenience.

Wind Chill Warning: Issued when wind chill temperatures are expected to be hazardous to life within several minutes of exposure.

Wind Chill Advisory: Issued when wind chill temperatures are expected to be a significant inconvenience to life with prolonged exposure, and, if caution is not exercised, could lead to hazardous exposure.

Winter Weather Advisories: Issued for accumulations of snow, freezing rain, freezing drizzle, and sleet which will cause significant inconveniences and, if caution is not exercised, could lead to life-threatening situations.

Dense Fog Advisory: Issued when fog will reduce visibility to ¼ mile or less over a widespread area.

Snow Flurries: Light snow falling for short durations. No accumulation or light dusting is all that is expected.

Snow Showers: Snow falling at varying intensities for brief periods of time. Some accumulation is possible.

Snow Squalls: Brief, intense snow showers accompanied by strong, gusty winds. Accumulation may be significant. Snow squalls are best known in the Great Lakes region.

Blowing Snow: Wind-driven snow that reduces visibility and causes significant drifting. Blowing snow may be snow that is falling and/or loose snow on the ground picked up by the wind.

Sleet: Rain drops that freeze into ice pellets before reaching the ground. Sleet usually bounces when hitting a surface and does not stick to objects. However, it can accumulate like snow and cause a hazard to motorists.

Freezing Rain: Rain that falls onto a surface with a temperature below freezing. This causes it to freeze to surfaces, such as trees, cars, and roads, forming a coating or glaze of ice. Even small accumulations of ice can cause a significant hazard.
