023 FXUS64 KSHV 141808 AFDSHV Area Forecast Discussion National Weather Service Shreveport LA 1208 PM CST Fri Nov 14 2025 ...New DISCUSSION, AVIATION, SPOTTER INFORMATION STATEMENT... .KEY MESSAGES... Issued at 1205 PM CST Fri Nov 14 2025 - Above normal temperatures through early next week will make for unseasonably warm afternoons and mild overnights. - Despite increasing humidity, a combination of warm temperatures, dry fuels, and breezy winds will keep conditions favorable for wildfires through the weekend. - A pattern change late next week will bring an increasing chance for heavy rainfall and possibly severe thunderstorms. && .DISCUSSION... Issued at 1205 PM CST Fri Nov 14 2025 The mid and upper level pattern across the CONUS this afternoon features an expansive ridge of high pressure over the Rockies and Great Plains, with longwave troughs located on both the upstream and downstream flanks, one closed and positively tilted along the West Coast and the other east of the Mississippi River through the Eastern Seaboard. Near the surface, high pressure extends over much of the SE CONUS, with influence extending into the TN Valley and into the Deep South. Arguably, the most impactful cyclone is located well into the Canadian Prairies, north of the polar jet that roughly skirts along the US/Canada border. With the above pattern in mind, it`s another quiet and warm day across the Four State Region as the local area remains influenced just enough by the mid/upper level ridge and sfc high pressure centered to the east. The scattered afternoon cu field will dissipate with loss of daytime heating this evening, yielding a mostly clear sky through the overnight period. Near-term model guidance is hinting at widespread fog development over the area tonight and early Saturday morning, and despite increasing moisture in the low levels in response to southerly return flow off the Gulf, there does appear to be enough evidence of a pressure gradient between the sfc high to the east and weak troughing near the OK Panhandle to keep winds elevated just enough overnight to prevent widespread fog. The greatest chance will be over far southern zones where the gradient and associated sfc winds look lightest. Patch fog is still likely to develop outside of this highlighted area in susceptible areas (ie., low-lying areas, areas in immediate vicinity of a water source or near a prescribed burn etc). The pattern hardly budges on Saturday with high pressure aloft lending to large scale subsidence over the region and another day of above average temperatures. A weak perturbation rounding the top of the ridge over the Southern Plains during the day will help develop of weak sfc low in the vicinty of the Red River along the TX/OK border which will keep the pressure gradient tight enough to elevate winds again Saturday, similar to Friday. While increasing low level moisture will keep min RH values closer to 50 percent, overall conditions for fire starts and spreads will remain favorable. By Sunday, the mid/upper level ridge will begin to break down/dampen some over the Four State Region in response to a strengthening trough over the Upper Midwest and Great Lakes Region, while it at the same time in starts to amplify along the Rockies in response to a deepening closed low over the Great Basin vicinity. While the overall atmosphere is likely to become somewhat unstable across the region on Sunday, the absence of any forcing for ascent, combined with enough lingering ridge influence will make for yet another dry and warm day featuring above normal temperatures where mid 80s for many locations near and south of I-20 appear very probable. Things begin to slowly change beginning early next week. Confidence is currently high in the Great Basin/Southern CA closed low ejecting NE into Central Rockies on Monday, supported in both the deterministic and most cluster analysis solutions. In response to the shortwave, lee cyclogenesis will take place across E CO/W KS, with frontal boundaries developing in association. This will yield a very low chance for a few showers or thunderstorms by Monday afternoon but without the aid of any synoptic scale feature, confidence remains low and will continue with an overall dry forecast. By Tuesday, the overall dynamics continue east and well to the north of the local area. It does appear that at least some weak sfc troughing along what is left of the cold front will work its way into the area. This could help make for a slightly better chance for isolated to perhaps scattered shower and thunderstorm activity Tuesday afternoon. Most guidance is not biting on the idea, likely given weak to potentially absent forcing. After this system moves well to the E/NE of the region, all eyes turn to the west where another longwave, closed area of low pressure will develop once again in the general southern CA/Great Basin area. This closed low will be able to push much deeper subtropical moisture into the area, via SW flow aloft as ridging develops on its downstream side. Current cluster analysis solutions are in excellent agreement with the development of this longwave trough, however, much uncertainty still remains in its actual placement, with some solutions having it develop and linger in the Southern CA/Great Basin area and others just offshore the CA Coast. This uncertainty in placement will have impacts to our region; namely in how and where it will shape the ridge downstream, which could shield the region from the deepest moisture, at least initially. Oftentimes, these types of lows are very slow to become progressive, and this is currently evident. That said, numerous perturbations will be ejecting NE from its base and into the Southern Plains. This is sure to eventually make for increasing rain and thunderstorm chances somewhere across the Four State Region. Right now, the Thursday- Friday timeframe appears most probable, beginning in northern and western zones and eventually shifting east along an associated cold front as the trough finally shows sign of some progression. While there is no real benefit to speculating which model or groups of ensemble solutions are correct at this point in time, taking the high confidence of the overall pattern change into account, there does appear to be an looming heavy rain and potential severe setup at the tail end of the forecast period of just beyond. 23 && .AVIATION... (18Z TAFS) Issued at 1141 AM CST Fri Nov 14 2025 For the 14/18z TAFs...scattered cloud cover will continue through the day with southerly winds staying steady around 8-10 kts. Winds will stay elevated overnight and hold off fog development for most areas tomorrow morning. Increased low-level moisture over the past few days could allow some low ceilings to develop around daybreak that will lift over the following few hours. Winds tomorrow will stay around 10 kts coming from the southwest. /57/ && .SPOTTER INFORMATION STATEMENT...
