214 FXUS64 KFWD 241925 AFDFWD Area Forecast Discussion National Weather Service Fort Worth TX 225 PM CDT Tue Sep 24 2024 ...New Long Term... .SHORT TERM... /Issued 1248 PM CDT Tue Sep 24 2024/ /Through Wednesday/ This morning`s showers and storms have mostly dissipated with the exception of some very isolated activity across portions of Central Texas. The remainder of the afternoon will feature warmer temperatures with highs in the mid to upper 80s. A lull in convective activity is expected for the next few hours, but a lingering frontal boundary across our southern zones will serve as a focus for additional scattered thunderstorm development late this afternoon. This activity will be confined to far Central/Southeast and should exit the area near sunset this evening. Locally heavy rainfall and lightning will be the main hazards. We`ll see another brief lull in rain chances this evening, but this will only be temporary as another shortwave trough will be digging into the Southern Plains along with its attendant cold front. Showers and thunderstorms are expected to develop in Oklahoma late this evening near the front and will continue moving south towards North Texas overnight. This activity should cross the Red River sometime after midnight and will continue south through much of the forecast area through Wednesday morning. While the potential for severe thunderstorms is low, adequate elevated instability and deep layer shear will support at least an isolated threat for a severe storm or two, mainly near and north of the I-20 corridor. The main hazards will be hail and damaging wind gusts. Rain chances will end from north to south Wednesday morning, with all activity exiting the area by mid to late morning. Winds will shift out of the northeast behind the front near 10-15 mph. As a result, cooler temperatures can be expected Wednesday afternoon with highs in the upper 70s to mid 80s. Barnes && .LONG TERM... /NEW/ Update: No major changes were made with this latest forecast update other than to incorporate the latest data from both deterministic and ensemble guidance. Fall-like weather conditions will continue through the rest of the week into this weekend, with most of the area remaining rain-free. There may be some wrap around showers across our northeastern zones on Friday, but otherwise expect mostly sunny skies with highs in the 80s and lows in the 60s. For more details, please see the previous discussion down below. Reeves Previous Discussion: /Wednesday Night Onward/ Seasonable, rain-free conditions are expected at the start of the extended forecast period as North and Central Texas remains situated on the backside of an upper level low. Highs Thursday will be quite similar to Wednesday`s, topping out in the low to mid 80s. Conditions will change slightly as the region will be under the influence of the upper level low retrograding further west Friday. As PTC9 moves inland and tracks around the upper low before becoming absorbed into its flow, wrap around moisture will be sent southward into the region, promoting low rain chances (20%) across the northeast Friday. Other than the low rain chances, slightly breezy conditions are expected as a result of this system, with peak wind gusts near 25 mph likely both Friday and Saturday. This upper level system will gradually shift eastward this weekend while ridging remains situated to the west. Increasing heights aloft will aid in warming surface temperatures, with mid and upper 80s anticipated Sunday and into early next week. Overnight lows will remain in the upper 50s to mid 60s throughout the period. Gordon && .AVIATION... /Issued 1248 PM CDT Tue Sep 24 2024/ /18Z TAFs/ VFR and light and variable winds will continue through the afternoon. A few isolated showers continue to stream across Central Texas, so VCSH was added to the KACT TAF through 19Z. More robust thunderstorm development is expected later this afternoon near a lingering frontal boundary in far Central/Southeast Texas, but this activity is expected to remain south of the KACT terminal. Otherwise, rain-free conditions are expected until late tonight when a cold front brings another round of showers and storms to the region. This activity should reach D10 airspace around 07-08Z and will impact most (if not all) TAF sites from 09-12Z. Winds will shift out of the north/northeast with the arrival of this activity, but wind speeds will initially remain light around 5 knots or so. Confidence wasn`t high enough to include a TEMPO for TSRA at KACT, but if storms do make it to the terminal, it would likely be between 12-14Z or so. Any stronger storms may produce strong wind gusts and hail, but the potential for severe storms will be quite limited and confined to North Texas. Showers and thunderstorms will end from north to south Wednesday morning, with north/northeast winds increasing to 10-15 knots around 14-16Z through the afternoon.
