Area Forecast Discussion
National Weather Service Lake Charles LA
1048 AM CDT Sat Apr 27 2019

.UPDATE...
Beautiful Saturday underway with abundant sunshine, warm
temperatures and relative humidity values between 45 and 60
percent. With high pres to the east, southerly winds have 
developed acrs the region. This will help dewpoints (and 
subsequently RH values) to creep upward later today and tonight. 
Some low level moisture return is already evident on vsbl 
satellite with sctd CU developing over SE TX, but overall expect a
sunny and warm (but not too humid) day today. Tweaked hourly 
temperatures and dewpoints this morning to bring in line with 
observations and short-term trends. This also resulted in a slight
upward adjustment to Max Temps for this aftn, but otherwise no 
significant changes were needed.

PREV DISCUSSION... /issued 318 AM CDT Sat Apr 27 2019/ 

DISCUSSION...
Wx map shows 1018mb sfc high pressure over SE TX/LA/MS this
morning, with mostly calm winds and clear skies. Temperatures this
morning continue in the lower to mid 50s across C LA & Inland SE
TX, mid to upper 50s across S LA. Across SE TX and extreme SW LA,
lower to mid 60s prevail due to weak return flow bringing higher 
dewpoints across this region, as well as patchy fog.

A benign weather pattern will continue through Tuesday with no 
precipitation expected. The major highlights will be high pressure
slowly moving eastward this weekend with weak southerly flow and 
a slow warming trend. Southerly winds expected to become stronger 
by Monday afternoon into Tuesday as low pressure intensifies 
across the Central Plains, increasing the pressure gradient across
the western portion of the sfc high across our region.

A series of upper level disturbances combined with Gulf moisture 
will yield increased chances of showers and thunderstorms 
Wednesday and Thursday of next week. Blended guidance keeps the
chances into Friday. 00Z GFS & ECMWF guidance diverges quite a 
bit by Friday, which in the springtime, is quite common.

Onshore flow will continue this weekend as high pressure moves east
of the region. Expect southerly winds to increase Tuesday and
Wednesday as low pressure intensifies across the Plains. A series
of upper level disturbances combined with Gulf moisture will 
yield increased chances of showers and thunderstorms Wednesday 
through Friday of next week.
