.PREV DISCUSSION... /issued 1026 AM CST Tue Jan 23 2018/

DISCUSSION...
High pressure continuing to build across the region to maintain
northwest winds around 5 to 10 mph today. Northwest flow aloft due
to upper-level ridge of high pressure across the Rockies to allow
for clear skies areawide. Otherwise, temperatures forecast to
climb to the upper 50s to around 60 today. Current forecast is on
track. No updates needed at this time. /05/

PREV DISCUSSION... /issued 455 AM CST Tue Jan 23 2018/

DISCUSSION...
The Four State Region will be under the influence of high pressure
on the surface and aloft for much of the rest of this week
resulting in a fair weather pattern with near normal
temperatures. Overnight lows the next couple of night will
lower to near or below freezing. During the late part of the
week the surface high pressure system will be shifting across the
Southeast States and along the Eastern Seaboard with the
upper ridge amplifying across the area that will result in
a warming trend with more moisture spreading North from
the Gulf of Mexico. A weak upper low underneath the upper
ridge aloft located over Mexico will open into a wave
and approach the forecast area late on Thursday and may
provide a slight chance of light rain with the returning
moisture. However, showers and isolated thunderstorms will
increase on Friday as a broad upper trough swings across the
Rockies and out into the Plains nudging a surface cold front
trailing from a surface low over the Great Lakes region and
Southern Canada into another surface low over Oklahoma and into
North Texas. A warm front will branch off the system over North
Texas and reach into the Gulf of Mexico. Widespread showers and
isolated thunderstorms will be ongoing for Friday night and
on Saturday as the cold front shifts East across the Four State
Region. Precipitation will be tapering off from West to East for
late Saturday night and ending on Sunday. High pressure on the
surface and aloft will be building over the forecast area
returning a fair weather pattern into the middle of the work week
with temperatures returning to near normal for this time of year
with lows in the 30s and highs near 60. /06/
