.SHORT TERM...
(Tonight through Monday night)

Wx map shows 1026 mb surface high pressure over Kansas, with weak
ridging southward to the Gulf coast. This continues northeast to
east winds around 5-10 mph across the area. Aloft, the east to
west axis oriented mid to upper level ridge continues across the
Gulf states, with a large vertically stacked low north of the
Great Lakes, keeping a fairly zonal flow across the northern part
of the country. Visible satellite imagery showing partly cloudy
skies with fair weather cumulus. Radar showing no precipitation.
Temperatures near 90/lower 90s across the area, and may rise a
couple of degrees more today. With the relatively lower dewpoints
in the upper 60s to lower 70s, heat index values ranging from the
mid 90s to near 100. For tonight, mostly clear skies with lows in
the upper 60s to lower 70s north of the U.S. 190 corridor, lower
to mid 70s further south.

Sunday, expecting weak surface high pressure to the north to
continue the light northeast winds. Afternoon highs expected to
climb a little higher in the mid to upper 90s. Precipitation
chances around 20% across Lower Acadiana, much less further north
and west, with a slight increase in the coastal waters south of
Vermilion and Atchafalaya Bays. Lows Sunday night/Monday morning
not as low, expecting lower to mid 70s along and north of I-10,
upper 70s to lower 80s further south.

For Monday, slowly increasing low level moisture expected as weak
south to southeast winds return across the area. Slightly higher
chances of showers and perhaps a thunderstorm by afternoon along
the I-10 corridor of Louisiana southward with 20-30%. Further
south into the coastal waters, chances increasing 40-50% Afternoon
highs in the mid to upper 90s expected. With the slightly higher
dewpoints in the lower to mid 70s along and south of I-10, heat
index values expected to reach the 105-108 range. Heat advisories
may be needed once again

.LONG TERM...
(Tuesday through next Friday)

The mid to upper level ridge will continue to be centered over the
region trough the period, continuing the much above normal
temperatures. Morning low temperatures in the mid to upper mid 70s
north of I-10, near 80/lower 80s I-10 south, with afternoon highs in
the upper 90s to near 100, except lower/mid 90s along the coast.
Maximum heat index values 103 to 108 expected, possibly higher in
some locations. Heat advisories may be needed.

Limited low level moisture, coupled with afternoon heating, will
yield isolated to possibly scattered afternoon showers and
thunderstorms along the I-10 corridor. Further north, chances
expected to be even less.
