754 FXUS64 KLCH 121607 AFDLCH Area Forecast Discussion National Weather Service Lake Charles LA 1007 AM CST Tue Feb 12 2019 .UPDATE... This morning's regional radar mosaic and surface observations show the initial cold front has pushed east into Acadiana. This front and the showers associated with it are expected to continue moving eastward and clearing the CWA by mid-afternoon. Overall, the forecast remains on track with only minor adjustments made to the PoPs through the rest of the morning to better match current observations and short term guidance. && .PREV DISCUSSION... /issued 539 AM CST Tue Feb 12 2019/ AVIATION...Showers are now exiting lower Acadiana associated with a pre-frontal trof that has advanced across the area. Patchy and light stratiform rains will follow this activity, then end from west to east through the morning as the main frontal boundary advances through. Clearing skies will then follow as sharply drier air through the column enters the area with the approach of the upper trof. Otherwise look for winds primarily from the northwest through the day sustained at 10 to 12 knots with gusts up to about 20. PREV DISCUSSION... /issued 443 AM CST Tue Feb 12 2019/ DISCUSSION... Overnight precipitation was associated with a prefrontal line of showers and thunderstorms ahead of the next front. Showers still linger behind the line of storms but will end around sunrise in southeast Texas and by the late morning hours for south central Louisiana. Current temps are in the upper 60s acrs srn Louisiana and near 70 for se Tx. The front is expected to move into Hardin and Taylor counties in the next hour or so with temps falling into the upper 50s. Currently Beaumont is 69 degrees. Therefore we are looking at about a ten degree drop with temperatures trending down through the day but will recover during the middle afternoon as skies will be clearing. The clear line is currently located along a line from Tyler to Austin moving southeast. For southern Louisiana this will take several hours longer but with the same out come. Winds will be strong and gusty in the coastal waters today with seas buildings a result. They are expected to settle this evening only to pick back up late tonight.
