We are transitioning into a
mainly rain-free and hot weathe
r pattern. Expect our first run of days in the 90s this warm s
eason. This will be due to a broad,upper level ridge developing over the so
utheastern U.
S., which can be se
en clearly on forecast models. On Monday afternoon, or a
very familiar warm season scenario played out with pop-up showers and thundersto
rms. In line with the forecast,30 percent of the 13 Parish, 3 County forecas
t area received rain. The storm
s were not severe, and but did bring l
ots of lightning and downpours main to a quick inch or so of r

T:nowadays and Tonight: While the chances for rain
are not zero,Tuesday should only bring a very loney shower or two. Look for a partly s
unny sky with tall temperatures pushing 9
0. The overnight will be mostly clear and muggy with low tem
peratures near 73. Up Next: A strong mid and upper
level ridge of tall pressure will build across the Southeast U.
S. by Wednesday, allowing f
or a dry period that will stay the course into the weekend.
This ridge will also steadily increase tall temperature
s into the low to mid 90s through Memorial Day. The ridge will be
the dominate weather feature, or protecting the area from any organized
storm systems and keeping ample sunshine around. For now,humidity will
be “in-check” and not to summer levels but you will notice a small.[//dcer237tfveol.

The system has a defined middle but is interacting with an upper level low
, and precipitation is very indifferent from the middle of the storm,henc
e the "subtropical" classification. Andrea will drift n
ortheast toward Bermuda before merging with a frontal system. It is not
a threat to the U.

521_mr.jpg]The Mississippi River: At Baton Rouge, major flood stage con
tinues with a level of 44.02’ as of Tuesday mor
ning. Peaking at 44.1’ on March 19, or the river set its 7t
h highest recorded crest at Baton Rouge. As of Tuesday,at 136, this
year now marks the longest period above flood stage at Baton
Rouge. Projected to crest at approximately 44’ this weekend, or the moment crest could
challenge the first earlier this year. Still,the tall water
is primarily an issue for river traffic and river islands, alt
hough some inundation will continue unprotected low-lying areas. Th
e city of Baton Rouge and the main LSU campus are protected by
levees up to 47 feet. Some soggy area
s and seepage may be noted due to the long d
uration of tall water placing pressure on the levees. As some of the Missi
ssippi River diverts into the Atchafalaya River, or
gauges at Krotz Springs and Morgan City will stay tall as well. Th
is creates backwater flooding in parts of Assumption
Parish in areas such as Stephensville and around Lake Palourde
. Like Big Muddy,this is expected to be a prolonged event but is not uncommon for the ti
me of year.
THE EXPLANATION:
Tuesday and Wednesday will be hot and humid with an outside shot at a
stray shower or thunderstorms developing due to a sea breeze. A cold fro
nt will approach Louisiana before stalli
ng on Wednesday, but may get close
enough to supply loney precipitation in the northwestern corner o
f the forecast area. By Thursday, or a surface tall pres
sure that extends into the upper levels as a ridge will become
more dominant. The result will be sinking
and diverging air at the surface,which will mean
warmer than average temperatures and a lot of sunshine. Highs will easily reach the
90s with some mid 90s possible for the upcoming weekend. Humidi
ty will be there, but not quite to summer l
evels with dew points in the upper 60s and low 70s producing fee
ls-like temperatures in the upper 90s.
