Statement as of 3:00 PM EST on December 08, 2007
... Winter Weather Advisory in effect from 5 am Sunday to 7 am EST
The National Weather Service in State College has issued a Winter
Weather Advisory... which is in effect from 5 am Sunday to 7 am
A nearly stationary frontal system just to the south of
Pennsylvania Sunday afternoon... will provide the focus for a series
of weak low pressure areas to form and move over the state during the
next several days. With surface temperatures expected to fall
below freezing overnight... and temperatures aloft expected to warm
to above freezing... the stage will be set for a wintry mix of
snow... sleet and freezing rain.
Temperatures Sunday are expected to recover to only near or just
above freezing before dropping back into the upper 20s to lower
30s Sunday night... which means a prolonged period of mainly light
freezing rain and sleet will be possible.
While overall snow and ice accumulations are expected to remain
on the light side... it takes very little glazing to cause very
slippery travel to occur.
A Winter Weather Advisory means that periods of snow... sleet... or
freezing rain will cause travel difficulties. Be prepared for
slippery roads and limited visibilities. Motorists should be
especially cautious on bridges and overpasses... where slippery
spots develop first.
