NWS Lake Charles, LA wrote its last area forecast discussion before the first event at May 9, 5:23 PM CST, 18 minutes earlier.
Area Forecast Discussion National Weather Service Lake Charles LA 623 PM CDT Sun May 9 2021 .UPDATE... Severe Thunderstorm Watch 160 has been issued until 06Z or 1 am CDT for mainly the northern zones, covering areas mainly north of the Highway 190 corridor. Concern is for cluster of thunderstorms across east Texas and northern Louisiana to consolidate into a MCS/Bow echo feature that will push east-southeast into the northern portions of the forecast area. Main hazards will be strong wind damaging wind gusts over 60 mph and hail larger than quarter size or 1 inch in diameter. && .DISCUSSION... For the 10/00Z TAF Issuance. && .AVIATION... Southerly flow will continue to move abundant Gulf moisture into the forecast area through the night. Low clouds will persist with mainly MVFR ceilings at all terminals. The next concern will be a complex of thunderstorms as an upper level disturbances moves across the region. KAEX terminal looks to be in the path of the developing thunderstorm complex, reaching that terminal after 10/01Z with affects possible through 10/05Z with IFR ceilings/Visibility and gusty winds. There is the possibility of this activity sinking further south overnight, and therefore added PROB30 groups at KLCH/KLFT/KARA to cover this after 10/09Z. Rua && .PREV DISCUSSION... /issued 339 PM CDT Sun May 9 2021/ DISCUSSION... A late season cold front is expected to reach our northern zones later today and become stationary over gulf coast states. Showers and a stray tstorm have already popped up in advance of this boundary and similar activity is expected for the rest of today and into tonight. This is a multi day rainfall event expected to extend into the end of this week. Rainfall totals for the short term are around a quarter to two inches. Issuance of a FF.A appear to be unlikely, however it is not completely out of the question. SPC D1 SWO has our CWA in a marginal risk for severe thunderstorms, with a slight risk for our northern SETX Counties and CenLA Parishes. On D2, our CWA again is in a marginal risk. All modes of severe weather are possible, with hail and damaging wind gust being the prominent threats. Overall, though, the threat remains low with most of the severe weather expected for areas north of us. 87 Long Term (Tuesday through Sunday)... The cold front that pushes through during the short term period is forecast by guidance to stall across the area through Wednesday with short waves moving through the southwesterly flow periods of showers and thunderstorms will continue across the area some of which could be on the heavy side with favorable flow and PW's 1.5 to 2 inches. The front gets a push to the south finally Wednesday night and Thursday with lingering showers possible Thursday morning before drier weather and briefly cooler temperatures especially at night. Guidance indicates return flow starting Saturday with a risk of showers and thunderstorms returning Sunday but the guidance is rather muddled on this right now. 27 MARINE... SC.Y from this morning was expired due to winds relaxing below criteria. Winds will continue to relax ahead of a stalled front well inland. Scattered showers and thunderstorms will be possible Monday into Thursday as this front provides a focus for storm development. && .PRELIMINARY POINT TEMPS/POPS...
