Area Forecast Discussion National Weather Service Shreveport LA 952 PM CDT Thu Jul 9 2020
Convection has long since come to a close for the evening, with no forcing mechanism to regenerate any more - evidence of the increasing influence of the upper ridge. See no need to hang on to the 20 PoPs across our ne tonight, so have removed those from the grids. Otherwise, temps in the lower 80s are running on track to dip into the mid 70s tonight with minimal cloud cover expected for the next few hours. Min temps and the remainder of the fcst appear reasonable, so will let the ongoing fcst ride as is. /12/
PREV DISCUSSION. /issued 726 PM CDT Thu Jul 9 2020/
Mostly VFR conditions to prevail throughout the 00Z TAF pd. Some patchy MVFR cigs will be possible around sunrise at E TX terminals, but any cigs should lift by mid morning. Otherwise, expect light and vrbl winds overnight to become swly around 10 kts or less after sunrise Friday. /12/
PREV DISCUSSION . /issued 234 PM CDT Thu Jul 9 2020/
SHORT TERM . /Tonight through Friday Night/ Northwest flow aloft, due to an upper-level ridge centered across New Mexico, to prevail during the short-term period ending Saturday morning. A disturbance within the upper-flow aloft to generate periods of convection mainly across southwest Arkansas and portions of northeast Louisiana early this evening with conditions improving throughout the night. Could see a few strong storms producing gusty winds early in the evening.
The main concern for the short term will be temperatures on Friday. Could see heat index values approaching 110 degrees across portions of south-central Arkansas and northeast Louisiana which would prompt a heat advisory to be issued across these areas during the overnight package.
Otherwise temperatures to range from highs in the low to mid 90s with lows in the mid to upper 70s. /05/
LONG TERM . /Saturday through Thursday/
Starting 12z Saturday . High pressure located across the Four Corners Region will continue to dominate the region through the weekend and into next week. The main concern in regards to the ridge of high pressure will be its movement and or expansion into the Southern/Central Plains next week.
Until that time, the position of the ridge, combined with a trough axis across the Appalachians will result in northerly to northwest flow across the Plains and into the Lower Miss Valley. Early on Saturday, we will be watching a disturbance move out of Eastern Kansas, moving into the Ouachitas of Southeast Oklahoma and South Arkansas by afternoon and this system will likely interact with daytime heating to generate at least isolated to widely scattered storms across our northern most zones. Similarly, another disturbance will move south and east in this flow Saturday Night into Sunday and this area of forcing could result in isolated to scattered convection once again across our far northern and northeastern zones late Saturday Night into Sunday.
Beyond Sunday, it appears the ridge across the southwest CONUS will begin to expand north and east into the Plains, thus ending northwest flow and ending any chance of precipitation across our region through at least midweek. There are some indications that before the flow shuts down completely, there may be a weak front that backdoors itself down into our region late Sunday/Sunday Night but have my doubts on just how far this boundary will make it. Wherever it is will wash out or lift back northward on Monday and then the heat is here to stay.
Concerning temperatures, stayed close to NBM temps for the upcoming weekend but beginning Monday and through the remainder of the extended periods went above NBM/MOS temps as an expanding mid level ridge certainly would not justify the cooler temps these models are forecasting in the extended. /33/

Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.
