| Area Forecast Discussion National Weather Service Lake Charles LA 1217am CST Tuesday Dec 16 2025 .SHORT TERM... (Today through Thursday night) Issued at 1215am CST Tuesday Dec 16 2025 Very cool and calm conditions are ongoing within the arctic airmass in place and under slight ridging in the mid levels. Cloud cover is moving in from the west, albeit much more slowly than previously anticipated. Due to this, temps dropped swiftly with sundown and majority of the region has been sitting within the 30s for 2 to 3 hours. Temps will slowly cool into the early morning hours with cenLA expected to fall into the upper 20s by sunrise this morning. No hard freeze concerns and calm winds will keep the wind chill factor to nearly zero. The only other outstanding change within the short term period are the increased rain chances late Tuesday into early Wednesday. Upper trough expected to move into cenTX is now anticipated to amplify further into south Texas. High moving off to the east and nearing trough will generate a small nocturnal jet maximum right across the TX/LA state line. This lifting feature should help to squeeze a few showers and perhaps embedded thunderstorms out over the forecast area from midnight Wednesday into the early afternoon when the trough washes out. Heavy rainfall / severe are not anticipated - however, read on for the meteorology nerd-speak for these next waves. The larger upper trough is then set to swing down into the central US on Thursday, a swift moving cold front arriving in its wake. Most guidance is still rather nil on MU CAPE for the Thursday frontal passage with values generally less than 1000 J. While low-CAPE-high- shear events are possible, this likely won't be one of those events. The parent low is far too far north to get the proper directional or magnitude shear needed to drive a severe risk. Rainfall totals between Wednesday and Thursday are generally less than 0.10", but don't be surprised if there are a few bullseye totals up to 0.50" over the short term. Forecast PWATs (Precipitable Waters) which would overlap with areas of best lift and instability are in the 80 to 90th percentile range for this time of year, so there could be some efficient rainers in the mix. Also considering the unidirectional flow overtop any convection (mostly Thu), there may be some repeated training cells. 11/Calhoun Long Term (Friday through Tuesday) Issued at 1215am CST Tuesday Dec 16 2025 Much cooler and drier air arrives Fridayam on the heels of departing dynamic upper shortwave system. A nice northerly breeze and slightly-below-normal temps will greet us on Friday afternoon. This cool reprieve from Wed/Thu's warmth will not last, though, as another low quickly dives out from the Rockies (perhaps lee cyclogenesis brought on by upper speed max?). Returning southerly flow is quickly enhanced by this developing weak low, bringing warm Gulf moisture back into the region. And from here, zonal flow develops aloft, shutting off the feed of dynamic frontal systems. Warm, well-above average temps and humid conditions will then prevail into the final days before Christmas. Only other note for the longterm... these back to back very cold punches have cooled the nearshore waters significantly. Returning warm and humid air overtop cool shelf waters can only mean one thing... marine fog! Tis the season! Perhaps we will have a White Christmas after all? 11/Calhoun Marine Issued at 1215am CST Tuesday Dec 16 2025 Winds turn onshore today ahead of another approaching upper disturbance. Breezy to occasionally moderate flow is possible through Thursday when the next strong cold front moves into the central Gulf. Winds will turn quickly offshore and strengthen Friday morning and a brief Small Craft Advisory may be needed during daytime hours. A return to onshore flow occurs by late Friday with warm moist air moving inland once again to the rest of the period. Cool shelf waters combined with warm moisture return and mostly calm conditions will likely bring back the occurrence of marine fog by the weekend. Fire Weather Issued at 1215am CST Tuesday Dec 16 2025 Winds to the east and then southeast today as high pressure moves to the east of the region. Moisture will start its return and daytime minimum RH values will range from 45 to 55 percent today; 70 to 80 percent Wednesday and Thursday. A series of disturbances will move near the region increasing rain chances early Wednesday and again Thursday ahead of a strong cold front. Wetting rainfall totals are not forecast. A brief period of strong north winds will bring south cool and dry air again on Friday. However, winds turn south again by late Friday brining heat and humidity right back into the region.
