Discussion
A LPS moved through Central Louisiana, this morning. There was a lot of shower
and thunderstorm activity associated with this system as it crossed over our
viewing area. Though there was a slight risk for severe weather, No watches,
warnings or advisories were issued this morning. The bulk of this system did
bring us some much needed rainfall and continued to push to the South East and
into the NE GoM (Gulf of Mexico). Today's High temperature was reached early
this morning as this front was moving through.
After a cold front moves through an area, a much colder and more dense air mass
moves in. This is called CAA (Cold Air Advection). As the cold air moves over
an area, daytime heating is over powered and suppressed. So in reality, the
actual temperature doesn't see much of an increase. Rather, it will be steady
for most of the midday hours, before falling as the sun begins to go down.
That is what is happening today. So, our overnight low will be at midnight,
tonight.
For the rest of the day,
In the wake of this most recent system, expect to see low rain chances,
followed by clearing skies this afternoon. Winds will stay moderate, gusty and
out of the North. We will also continue to see the temperature drop throughout
the day. Expect mostly cloudy skies,
becoming partly cloudy with cooling temperatures and rain chances remaining
low. Overnight we will see skies become clear with lows reaching the lower to
mid 30's.
For the rest of the 7day planner
After this front pushes completely out of the area, a dry, mid-week, cold air
mass will move overhead. Rain chances will return during the PM hours on
Thursday as low level energy begins to allow a southerly flow, off the gulf, to
develop. The next piece of energy will move through the area Thursday night and
early Friday.
Temperatures will drop into the 30's Tuesday and Wednesday night.
THIS AFTERNOON...Mostly cloudy skies with
clearing and cool. Temperatures will stay near steady and in the 50s. Off/on
drizzle or light rain remain possible but very low chances. N/NE wind 8-16 mph.
TUESDAY NIGHT...Continued clearing and colder. Lows 35-41. North wind 2-10mph, becoming calm.
