Area Forecast Discussion National Weather Service Lake Charles LA 946 PM CDT Fri Oct 15 2021

UPDATE.

Much anticipated cold frontal boundary beginning to slip through the forecast region this evening. A broken line of convection accompanying the front has largely waned here in the last hour or two. Still, 00z LCH raob sampled MUCAPE ~1500 J/kg, so combined with convergence along the boundary, will maintain the chance for some isolated to scattered thunderstorms before the front fully passes. Overall, made fairly minor grid adjustments to incorporate recent short term and high resolution guidance. Post- frontal winds will remain the primary forecast issue over the next 24 hours or so. Had considered issuing a Wind Advisory for coastal counties/parishes for a portion of tomorrow, but for now will opt to let the overnight crew make the final decision with the last round of guidance. In any case, CAA with a tight post- frontal gradient will result in breezy conditions. That said, only maintaining the current hazards (Gale Warning / Small Craft Advisory) as they are with this evening's update.

PREV DISCUSSION. /issued 604 PM CDT Fri Oct 15 2021/

DISCUSSION . 00Z TAFS.

AVIATION . Line of SHRA/TSRA just ahead of the strong cold front from POE southwest into SE TX approaching BPT within the next hour, and LCH in about 2 hours. Placed TEMPO groups for the TSRA at BPT through 02z, LCH from 01-03z, 02-04z for LFT/ARA. The northern end of the line has diminished enough to just leave VCTS for AEX through 02z. Winds will shift to the NNW around 10-12 kts with gusts near 20 kts after the frontal passage this evening, with winds gradually becoming northerly and increasing to 15-17 kts with gusts near 23-25 kts by 15Z Saturday. VFR expected after the cold frontal passage.

PREV DISCUSSION . /issued 343 PM CDT Fri Oct 15 2021/

SHORT TERM [Tonight through Sunday] .

Much advertised CDFNT currently stretches NE to SW across eastern and southern TX, and is very near College Station. Pre-frontal convergent bands are yielding scattered showers and an isolated thunderstorm or two, with convection having a similar character along the front itself. Veered winds ahead of the front and limited upper level support are resulting in relatively weak lift, so expect convection to remain largely status quo as the front pushes through the area tonight. Boundary is expected to enter Tyler County around 7 PM give or take, and is forecast to have cleared St. Mary Parish by 3 AM if not sooner. Brisk and gusty north winds will follow the frontal passage, along with an intrusion of much cooler and drier air, with lows SAT morning in the mid 50s NW to the lower/mid 60s SE.

North winds will remain elevated into SAT, with latest short range guidance flirting with wind advisory conditions, especially along and south of the I-10 corridor. Will hold off for now and let the next couple of shifts further evaluate. Amid ongoing CAA and despite ample sun, temperatures SAT afternoon will struggle to reach the mid 70s. Winds will subside SAT night as high pressure at the SFC and aloft settles into TX, though they are not expected to be completely calm. Still, with the bone dry airmass in place (PWATs progged to be near the minimum moving average for this time of year) underneath a clear sky, good radiational cooling is expected, and lows SUN morning are forecast to be the coolest of this forecast period and the Fall season thus far, ranging from the mid to upper 40s north to around 50 along the I-10 corridor.

Quiet and cool weather will continue on SUN as the high pressure to the west slides east into the region, with highs again perhaps reaching the middle 70s. Some increase in mainly mid/high level cloud cover is expected SUN afternoon and night ahead of an approaching shortwave trof, which along with some slight airmass moderation, will help hold temperatures SUN night/MON morning a little higher, ranging from the upper 40s to lower 50s.

LONG TERM [Monday through Saturday] .

At the start of the long term period the forecast area will remain under the influence of high pressure both at the surface and aloft. Aloft, ridging extending from the Northern Plains to the Gulf Coast will remain in control through the mid-week, while gradually sliding east. At the surface, a high pressure ridge over the SE US will gradually slide eastward through the mid-week as well. The slow departure of the surface high will result in a return of east to southeasterly winds by Tuesday as well as a slow warming trend. Highs in the mid 70s on Monday will rebound back into the low to mid 80s by Wednesday. East to southeasterly flow will be slow to bring moisture back into the region, so rain chances will remain near zero through the first half of the week, while humidity will be slow to return as well.

Moving into the second half of the week, the pattern begins to change as the long term models continue to signal to another frontal passage. A weak upper level low will move across the Plains and into the Midwest late Wednesday into Thursday, which should send a cold front through the CWA sometime around the Thursday/early Friday timeframe. Biggest question at this point is the strength of this front, as the models have not been in agreement this far out. Currently, it doesn't look like this front will be as strong as the one moving through tonight, but it should still be able to bring an end to next week's warming trend.

17

MARINE . A light onshore flow will continue through early evening, with winds veering to the north and becoming strong and gusty behind a cold front expected to push through the coastal waters tonight. Have hoisted a gale warning for the Gulf waters and a SCY for the coastal lakes and bays from mid evening tonight through noon Saturday, but additional hazards will likely be needed as north winds will remain elevated and gusty through the afternoon, before starting to subside tomorrow night as high pressure settles into the region. Winds are expected to gradually shift to the southeast by midweek as the high moves off to the east.
