567 FXUS61 KRLX 191021 AFDRLX AREA FORECAST DISCUSSION National Weather Service Charleston WV 521 AM EST Wed Nov 19 2025 .SYNOPSIS... High pressure supports mostly dry into Friday morning. Better chances of rain arrive late Friday night and continue into Saturday. A more potent system arrives possibly Tuesday. && .NEAR TERM /THROUGH TONIGHT/... As of 130 AM Wednesday... A dry and seasonable day on tap as a system that brought all the rain here recently kicks out to the east and leaves behind wrap around flow off the Great Lakes to create an abundant moisture flux. This will aid in the development of low stratus clouds area-wide spreading across our CWA this morning. Due to the lack of surface flow and the abundant low level moisture these clouds will take until the afternoon to lift, however they will not scour out as cloudy conditons will persist through the period. Wouldn`t be surprised if some areas receive some drizzle on and off through the period although the probability is too low to place into the forecast solution for today. The blended model guidance did not offer to comment on that possible solution, therefore went with guidance as per directive orders since not enough scientific evidence suggests widespread drizzle. Tonight, we cannot rule out a rogue shower or two as cloud coverage will be abundant along with northerly flow turning to more southwesterly advecting in more moisture from the south which place the probability of rain showers capped off at around 20% and chances should only last into Thursday morning. Temperatures overnight will not change or drop much from the daytime as cloud coverage will help in suppressing radiational cooling even though surface flow will be calm. && .SHORT TERM /THURSDAY THROUGH SATURDAY/... As of 130 AM Wednesday... Thursday looks to be dry as weak upper level ridging builds in although surface high pressure pulls back with lowering heights in anticipation of a feature bringing plenty of moisture and precipitation coming this way fromm the Texas area, thanks Texas, following anti-cyclonic flow around the upper level ridge. As zonal flow kicks in that precipitation will make it into our area raising the probability of rain to 20-70% by Friday morning. Models have the systems warm frontal boundary draped across the area for Friday raising the chances for thunderstorm activity during the evening and nighttime with chances up to around 20% therefore worst case we see af few rumbles since instability will be low at that point. Chances will stay elevated for all of Friday with probabilities upwards near 90% into Saturday morning as that aforementioned system passes through. The system cold be delayed somewhat, so worst cast scenario would be probabilities for rain falling for the daytime on Saturday to around 60%, and then slowly tapering off to around 30% for the evening which will continuing into Sunday morning. && .LONG TERM /SATURDAY NIGHT THROUGH TUESDAY/... As of 130 AM Wednesday... By late morning Sunday, chances for rain drops off and will be just confined to the mountains at around a 20% or less probabilities for light shower activity. Rising surface heights and weak upper level ridging will reinforce dry weather for the rest of Sunday and into Monday. Chances then come back to fruition Monday afternoon as another system is forcast to move off from the West Coast past Texas, thank you again Texas, and into our region by this time frame. This system is forecast to evolve into a more potent system then what we have been observing lately. Probabilities for activity will be on the rise from Monday going forward as models are in fairly good agreement on timing and track of this system to affect the area possibly by Tuesday. && .AVIATION /10Z WEDNESDAY THROUGH SUNDAY/... As of 530 AM Wednesday... Low stratus will invade the area for this period. CIGs will slowly deteriorate through the morning becoming IFR and even LIFR at times. VIS should bounce around somewhat due to the cloud coverage amid weak surface flow but not anticipating long term IFR VIS. Clouds will lift some by the afternoon but will stay MVFR for the duration. Dry weather should persist, however there could be instances of drizzle under overcast low clouds and plenty of low level moisture. By Thursday morning, clouds will still dominate the region and VIS restrictions should be confined to the mountains although some restrictions could spill over into the lowlands because of recent rainfall and abundant low level moisture, however should not be as bad if it were a clear and calm morning. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 12Z THURSDAY... FORECAST CONFIDENCE: Medium to high. ALTERNATE SCENARIOS: VIS will likely vary between MVFR/IFR this morning under low stratus. Heights of low stratus may vary from 200 to 800ft through late morning.
