436 FXUS64 KAMA 101740 AFDAMA Area Forecast Discussion National Weather Service Amarillo TX 1240 PM CDT Thu Jul 10 2025 ...New KEY MESSAGES, SHORT TERM, LONG TERM, AVIATION... .KEY MESSAGES... Issued at 1142 AM CDT Thu Jul 10 2025 Thunderstorms today, Friday, and Saturday have a low chance of becoming severe. Damaging winds and hail are the primary hazards. Increasing moisture will allow for heavy rainfall and flooding risk Friday through the weekend. Daily thunderstorm chances continue into next week. && .SHORT TERM... (This afternoon through Friday night) Issued at 1142 AM CDT Thu Jul 10 2025 A weather system is moving across the southern plains today bringing mid level moisture across the panhandles. Daytime heating and instability associated with this weather system is already sparking high based rain showers. As the day progress further high based rain showers and thunderstorms will have a moderate to high chance of forming. These will most likely form a loose line of storms that will transit slowly from the NW panhandles to the SE panhandles. There is a deep sub cloud base dry layer which will mitigate some of the rainfall from any rain shower or thunderstorm. However this will make these storms far more efficient wind producer with any of them able to produce downburst wind. There is a low chance that a few of the storms will become strong to severe with even stronger downburst winds and large hail. As the loose line of rain showers and thunderstorms move into the central panhandle during the evening the loss of heating and the weakening of the weather system will cause them to dissipate. During the overnight hours a low level jet has a high chance of forming across the panhandles. This jet is very significant as it will help shunt a large amount of low level gulf moisture quickly in the southern plain including the panhandles. This additional moisture will provide further fuel for Friday as another small weather system moves into the panhandles. This system will in turn cause rain showers and thunderstorms that move NW to SE across the panhandles during the afternoon and evening. The storms then have a moderate chance of persisting through the overnight hours into Saturday morning. With the additional moisture the amount and coverage of these storms will be higher than today with the whole panhandles having a chance of seeing precipitation. Even with the relatively small weather system there is a low chance that a few storms become strong to severe with large hail and damaging winds. The increased moisture will bring a new threat in that these storms will be capable of producing heavy rainfall that can lead to flooding. Just to emphasize the significant nature of the moisture it will be building to upwards of 1.5in PWAT. This puts it near the maximum moisture that we typically see for this time of year. The increase in moisture will also herald the return of more muggy weather compared to our more typical dry heat. A silver lining with the moisture increase is that the temperatures will be falling with high in the 90s to 100s today dropping to the low to mid 90s for Friday. && .LONG TERM... (Saturday through next Wednesday) Issued at 1142 AM CDT Thu Jul 10 2025 The southern plains including the panhandles will have a high chance of staying under a stagnant pattern of a high pressure to the west and east of the region while a broad trough stay over the region. This pattern will remain very favorable for pushing increasingly copious amounts of Gulf moisture into the panhandles. The broad trough along with daytime heating will provide the instability needed for rain showers and thunderstorms to form. So for each day there will be at least portions of the panhandles that will have a moderate chance for rain showers and thunderstorms. The moisture will remain extremely high with PWAT increasing further with at least a low-moderate chance that 1.5-1.8in PWAT move into the panhandles. This moisture is darn near or exceeding the maximum we see in the panhandles for any of these mid July days. Indeed if we are on the higher end of the range this moisture would be some of the highest ever seen in the panhandles. With such high moisture heavy rainfall may occur with any rain showers or thunderstorm that form in the panhandles. The threat of heavy rain will then persist for so long as this high moisture remains across the panhandles. The silver lining will remain through the weekend into next week as the moisture leads to cooler temperatures even if it will lead to muggy days. && .AVIATION... (18Z TAFS) Issued at 1142 AM CDT Thu Jul 10 2025 A weather system will produce high based rain showers and thunderstorms in the panhandles this afternoon through to the evening. There is a low chance that these will impact the terminals during this time. A few of the storms have a low chance of becoming strong to severe producing strong downburst winds. Conditions are most likely to remain VFR even with the passage of a thunderstorm. If conditions did lower from thunderstorms it is most likely to MVFR. Otherwise ambient winds will be gusty from the south during the daytime hours becoming weak for the overnight. There is a very low chance that further rain showers or thunderstorms develop during the overnight hours, this will not be reflected in any TAF. Active weather continues on Friday as more rain showers or thunderstorms are expected for that day. && .AMA WATCHES/WARNINGS/ADVISORIES... TX...None.
