Area Forecast Discussion National Weather Service Lake Charles LA 441am CST Fri Nov 22 2019 12Z Taf issuance. Radar depicting some very light and patchy returns across the area, primarily sprinkles. Skies are cloudy across the entire area with satellite water vapor imagery showing a well defined moisture plume in place incoming from the southwest. Satellite additionally depicted mid/upper low spinning over eastern Colorado. This feature forecast similarly by models to continue an eastward advance, sending a cool front across the forecast area late this afternoon and overnight. Surface obs currently depicting temperatures in the mid 60s to lower 70s resulting from a moderate low level southerly flow in place and aided by the lack of any radiational cooling from extensive cloud cover. Temperatures are closer to normal late November highs. Expect little if any further fall through the remainder of tonight. Aforementioned Colorado low expected to advance across the central plains today and into the mid-Mississippi valley late tonight. Feature will bring a rather slow advancing northeast to southwest oriented cool front into the lakes area of southeast Texas early this afternoon, reaching along a line from Alexandria to Lake Charles toward mid evening, and over and through Acadiana later tonight. The evening LCH sounding came in with an already impressive PWAT (Precipitable Water) of near 1.5 inches. PWAT (Precipitable Water) forecast to continue an upward advance to an extreme 1.75-2.00 inches along and ahead of boundary...or in the ballpark of a daily max. At this time looking for area coverage of rains generally in a 0.5 to 1.5 inch range as widespread showers and a few thunderstorms develop along and ahead of the boundary. Due to the extreme PWAT (Precipitable Water) however, and potential for convective training, some localized flooding will be possible. Potential just not high enough at this time to issue a Flood Watch. Some severe threat will also exist for damaging wind gusts and isolated short-lived tornadoes as moderate deep layer shear profiles develop. A weak thermodynamic environment however will act to limit the severe threat. Rains will taper off with the FROPA and with sharply drier air incoming the weekend appears good weather-wise. Pacific origin of the front will limit any significant cooling and temperatures will simply slip down to at/or slightly below seasonal norms. Skies will clear west to east as Saturday progresses and expected all of the forecast area to be sunny by days end. Sunday and Monday will start off clear and cool, with a nice warmup through the day under sunny skies. Rain chances then make a return for Tuesday as our next front approaches. Marine Discussion A light to moderate onshore flow will continue today with widespread showers developing as well as a few thunderstorms along and in advance of an incoming cold frontal passage. The front is expected to move across the northwest Gulf mainly through the overnight hours with rains diminishing in its wake and winds becoming northerly.
