Area Forecast Discussion National Weather Service Lake Charles LA 1253 PM CDT Sun Jun 28 2020 .DISCUSSION... 18Z TAFS && .AVIATION... VFR conditions expected to prevail this afternoon through tonight. Scattered showers and thunderstorms developing in the vicinity of a weak upper level disturbance will continue to lift to the north through the afternoon before dissipating around sunset. Breezy southerly winds owing to a moderate pressure gradient between a surface high over the southeastern gulf of Mexico and a deepening low over Colorado will maintain moderate southerly winds through the evening besoming a bit lighter overnight. MVFR Cigs early Monday morning will lift to VFR by afternoon. Isolated, diurnally driven showers and thunderstorms will redevelop beginning late Monday morning, but negligible upper level support will keep this activity limited. Jones && .PREV DISCUSSION... /issued 1032 AM CDT Sun Jun 28 2020/ DISCUSSION... Wx map shows surface high pressure ridging westward across the Eastern Gulf, continuing a very humid southerly flow off the Gulf. Visible satellite imagery shows partly to mostly cloudy skies with continued haze. Temperatures in the mid to upper 80s across the areas, with dewpoints in the upper 70s to near 80 already yielding heat index readings in the mid 90s to lower 100s. Expect the dewpoints to lower may a degree or two as temperatures rise into the lower 90s. Heat index values expected to top out 102-105 by mid to late afternoon. Radar showing isolated showers over Western Louisiana, scattered over Southeast Texas. Shower and isolated thunderstorm activity expected to increase a bit by afternoon, going 30-40% along and north of I-10, 20% or less south of I-10 into the coastal waters. DML PREV DISCUSSION... /issued 702 AM CDT Sun Jun 28 2020/ DISCUSSION... For the 06/28/20 1200 UTC TAF package. AVIATION... Mix of VFR and MVFR early this morning as areas of low clouds have developed across parts of the region. The most persistent MVFR CIGS are expected at KAEX and possibly KBPT this morning based on satellite imagery, with VFR expected mostly prevail elsewhere. These MVFR CIGS are forecast to lift/scatter out mid to late morning, with VFR prevailing the rest of the forecast period away from convection. Best TSTM chances will reside across central LA this afternoon, so have continued with a PROB group at KAEX. Winds out of the south will increase and become a bit gusty this afternoon before subsiding early evening. 13 PREV DISCUSSION... /issued 433 AM CDT Sun Jun 28 2020/ SYNOPSIS... Sfc high pres continues to ridge acrs the northern Gulf coast, with southerly winds maintaining transport of warm and moist Gulf air into the area. Temperatures this morning are similar to the past several morning with readings in the middle/upper 70s to near 80. Dewpoints at most locations are at or within a couple of degrees of the air temps, making for yet another very humid night acrs the area. Satellite imagery shows quite a bit of high clouds streaming over the region, with lower clouds developing acrs the northern half of the area. KLCH radar remain relatively quiet, with just some spotty showers developing over the coastal waters. Latest UA analysis and WV imagery shows a disturbance exiting Old Mexico, moving into TX, while a ridge continues to build west acrs FL into the Gulf of Mexico. 24 DISCUSSION... The disturbance near the Rio Grande Valley this morning will lift northeast acrs TX today. Given the proximity of this shortwave and the main mid/upper ridge axis oriented southeast of the area, as well as ample moisture in place, sctd showers and tstms are expected to develop by mid to late morning and continue into the aftn, with coverage possibly approaching 40 percent during the aftn peak. Severe weather is not anticipated with any storms today, but some pulse storms could produce brief strong gusts. Daily rain chcs will decrease from Monday through midweek as the Gulf ridge expands west. Carried slt to low end chc pops on Monday as moisture interacts with daytime heating and the seabreeze. By Tuesday and Wednesday, the ridge aloft will expand further west acrs the area into TX, and rain chcs will be lowest on these days. Slt chc pops begin to edge back in the area from the east by Thursday, as the suppressive influence of the ridge shifts west. Daytime temperatures will steadily climb through midweek. Highs today are expected to reach the upper 80s to around 90, with lower to middle 90s expected for highs by Wednesday and Thursday. With southerly low level winds continuing, elevated dewpoints in the 70s are expected, keeping humid conditions acrs the region. The combination of warmer temperatures and high dewpoints will result in heat index values between 100 and 105 by Wednesday and Thursday. While this is below advisory criteria, individuals are still encouraged to take precautions (such as drinking extra water or seeking shady locations) during outdoor activities. Elevated shower and tstm chcs will return after Thursday and continue into next weekend as the pattern aloft becomes more amplified. The disturbance traveling acrs TX today will become cutoff acrs the cntl CONUS by midweek. This low is expected to gradually settle acrs the lower MS Valley/SE states as the TX ridge builds north over the front range of the Rockies. Northerly flow developing between these features will bring a weak frontal boundary southward into N LA Friday. Moisture deepening over the area, in concert with the approaching boundary and upper trough axis sliding into the region, will unfortunately result in convection becoming more widespread in time for the Independence Day weekend. 24 MARINE... No significant marine issues are anticipated as southerly winds continue into next week with sfc high pres situated over the northern Gulf. Winds will become more southwesterly toward the end of the week as a weak frontal boundary stalls north of the region. 24 && .PRELIMINARY POINT TEMPS/POPS...
