for 12z tafs
/issued 434 am CDT Friday Oct 31 2014/
a shortwave moving across the area is currently producing light rain
to virga in northwest Alabama. The trough out of the Great Lakes will dig
southeast today with an associated trailing cold front. Once this
shortwave moves through...winds will become northerly but the main
front will arrive later this afternoon. Behind the main front is
where the winds will pick up and the cold air will filter in. A few
showers are also possible with this frontal passage...not enough to
scare away any ghosts or goblins...but may want to secure down any
decorations with the wind gusts this evening and Sat morning
approaching 25 to 30 miles per hour. With the breezy winds this evening...be
sure to bundle if going out as as it may feel a little bit colder
than the actual temperature.
Overnight lows will dip towards the freezing mark...thus have issued
a freeze warning for north Alabama and southern middle Tennessee.
Temperatures will range from 29 to 32 for a few hours tonight. As the low
lifts northeast Saturday...winds will still be breezy in the morning.
Highs will be chilly striving to reach 50 degrees. As high pressure
builds in from the west...winds will slack allowing Sat night/Sun
morning lows to cool even further. Depending on how widespread
freezing temperatures are seen Sat morning...will have to reassess the need
for a freeze warning for Sun morning. Temperatures Sunday morning will be in
the upper 20s. As the high pressure moves off towards the East Coast
and southeasterly winds will return on Monday allowing for a warm up
to return for the work week...high temperatures around 70.
Another cold front will approach the area Tuesday night/Wednesday morning.
Rain showers are possible Wednesday and may linger towards early Thursday. No
major temperature drops are anticipated with this cold front like we will
see this weekend.
for 12z tafs...a cold front...now over western Tennessee...will continue to move
east today. Since there could be a few rain showers along the cold front...will
include vcsh in tafs between 17z and 22z. As the cold front moves out of
the County Warning Area this afternoon...winds will increase to 15kt with gusts around 25kt.
Winds will diminish to around 10kt tonight. Otherwise mainly VFR
conditions are expected through the forecast period.
Alabama...freeze warning from 4 am to 9 am CDT Saturday for alz001>010-016.
Tennessee...freeze warning from 4 am to 9 am CDT Saturday for tnz076-096-097.
