Area Forecast Discussion National Weather Service Lake Charles LA 634 PM CDT Wed Jul 17 2024 ...New AVIATION... .SHORT TERM... (Tonight through Friday night) Issued at 335 PM CDT Wed Jul 17 2024 Mid-afternoon sfc analysis shows the Bermuda high pressure ridge continuing to stretch wwd across the nrn Gulf, maintaining an onshore low-level flow across the region. Meanwhile, a weak cool front is noted to our north, extending from the Ohio Valley through the Ozarks to the Red River Valley. Water vapor imagery shows the wrn Gulf within troffing extending from the Great Lakes sswwd. With the area remaining quite moist (regional 12z soundings showed PWATs generally around 2 inches) and no real capping present thanks to the trof, convection was gradually developing across mainly the srn/ern portions of the forecast area earlier. Meanwhile a 2nd area of convection upstream associated with an advancing weak disturbance was noted over nern TX. The key messaging in the short term continues to be wet weather persisting. Today's diurnal convection is expected to begin petering out as we approach sunset, with a few showers/storms possibly extending a short time after sundown. The late evening/early overnight looks dry before a combo of factors lead to more convection developing towards sunrise...the typical nocturnal maritime activity develop/moving ashore across the far srn zones, while additional activity developing with the disturbance dropping through the trof and ahead of the approaching sfc boundary begins impacting the far nrn zones. High POPs are on the books again for Thursday as the sfc boundary slips into the forecast area, adding additional lift to the already very moist airmass (mean RH values 70 to 80 percent and PWAT values up 2.2 inches) and nil capping. Given the potential for slow- moving convection and the high PWATs (around the 90th percentile per SPC raob climo), WPC has highlighted the entire forecast area in a marginal risk for excessive rainfall for tomorrow. With this activity not being entirely diurnally driven, high rain chances linger right through Thursday night into early Friday morning. Wash, rinse, repeat for Friday as the lingering boundary, progged to meander around the region, overhead trof axis/general mid-level weakness and copious moisture result in yet more widespread shower/thunderstorm activity...with the WPC maintaining the marginal risk. Some relief looks possible for Friday night as the trof axis finally slides ewd, with much smaller POPs in the forecast for the nwrn zones into w-cntl LA. With the widespread cloud cover/precip, heat index values are not expected to meet advisory criteria at any point during the short term. && .LONG TERM... (Saturday through next Tuesday) Issued at 335 PM CDT Wed Jul 17 2024 A very wet and rainy longterm period is in store as a series of shortwave trof pulses work around a low pressure center parked over the north Central US. Buoyant and deeply moist airmass in place ahead of these shortwave perturbations will allow widespread convection to develop each day in southeast Texas and southwest Louisiana. Forecast PWATs 2.00 to 2.30 inches and warm-column soundings indicate warm-rain processes will be in place, making for very efficient downpours. With more and more rainfall piling on through the short and then long term periods, the threat of urban and localized river flooding increases. The Weather Prediction Center has placed most of the area in a Marginal Risk (1 out of 4) of Excessive Rainfall on Saturday and the entire area in a Marginal on Sunday. This indicates there could be rainfall rates which could lead to aforementioned flooding concerns. With little break in the pattern seen for Monday and Tuesday, it is likely that more Excessive Rainfall Outlook areas will be drawn up for these days. Keep those rain boots handy! Widespread rain-cooled air and cloud cover will keep temperatures in check for the weekend and start of the work week. High temps should only top out in the upper 80s to around 90 F each day. Elevated dewpoints, however, will keep the overnight hours feeling very warm and muggy in the low to mid 70s. 11 && .AVIATION... (00Z TAFS) Issued at 628 PM CDT Wed Jul 17 2024 Mostly VFR conditions ongoing outside of a few storms across parts of SETX and CenLA. This activity will taper out later in the evening, with a quiet night expected. There is an outside chance of patchy fog, however no significant impacts are expected as a result of it and whatever does form will lift after sunrise. Similar conditions are expected tomorrow afternoon and evening with showers and storms ramping up in that period. Stigger/87 && .MARINE...

1057 AM Tornado 5 S Jasper 30.84N 94.00W
07/08/2024 Jasper TX NWS Storm Survey
*** 1 INJ ***
A National Weather Service storm survey
revealed that an EF-2 tornado impacted areas
near Jasper, Texas. The tornado touched down
somewhere in the Little Walnut Run Valley
and tracked about 12 miles to the northwest
lifting somewhere in the Indian Creek
Valley. The tornado also tracked through the
west side of the city of Jasper. Numerous
power poles and trees were snapped or
uprooted. Numerous homes and outbuildings
were heavily damaged. The tornado weakened
as it crossed Highway 190 in Jasper, only to
regain EF-2 strength as it crossed Houston
Street in a wooded area. There was one
injury associated with this tornado. The
path was extended 07/17/2024 to both the
southeast and northwest with the aid of high
resolution satellite imagery provided by
NASA MSFC, NASA CSDA and the NASA Disasters
Program.
