Slow Moving Cold Front Moves into the Central U.S.

A slow moving cold front continues to move eastward across the U.S. this weekend. Behind the cold front is unseasonably cold weather and high elevation snows; ahead of the front, temperatures are more typical of mid-summer. The front separating these extremes will help focus heavy rain, with the potential for flash flooding extending from eastern New Mexico and western Texas to the Upper Midwest. Read More >

Area Forecast Discussion
National Weather Service Shreveport LA
302 PM CDT Sat Sep 23 2017

.DISCUSSION...
Isold convection ongoing across the region this aftn, as daytime
heating and sufficient moisture overpower the the influence of
the upper ridge. Weak upper low over the se CONUS will continue to
drift wwd and linger through Monday, providing some help for
isold to widely sct convection to overrule the upper ridge`s
stronghold.

Cold front/large-scale upper trof will move into the plains in the
mean time, and begin approaching our region Tuesday into
Wednesday. Some chances for rain will accompany the front,
although they will be rather low-end and focused across only the
nwrn portions of our region. The ridge will continue to hold its
ground through late in the work week, until the upper trof
/reinforced by additional disturbances/ finally is able to ride
over the ridge and force it swd. This will not mean much for us in
terms of getting any rainfall, but it will allow for the
accompanying Canadian airmass to filter into our region and cool
our temps down to a more respectable level for fall. /12/
