174 FXUS61 KRLX 061024 AFDRLX AREA FORECAST DISCUSSION National Weather Service Charleston WV 624 AM EDT Sun Jul 6 2025 .SYNOPSIS... High pressure promotes dry, but hot weather through the holiday weekend. A weak cold front brings back the chance for showers and thunderstorms to begin the new work week. && .NEAR TERM /THROUGH TONIGHT/... As of 200 AM Sunday... Today we have a sort of sandwich pattern going on with an approaching frontal boundary to our west, which is forecast to impact the area for Monday and Tuesday, then we have a tropical disturbance from the southeast which will graze our eastern border of West Virginia to where chances of shower/thunderstorm activity will be possible today. We will be nestled under high pressure holding back most activity potential for the rest of the area. Temperatures today will rise in the low to mid 90s for the lowlands and upper 70s to upper 80s for the mountain counties. With dewpoints in the mid 60s we will not have to worry about heat indexes as they will remain below the 100 degree mark. We may even get a slight breeze going today in the afternoon with some mixing and the pressure gradient getting squeezed. A cumulus field should develop, but will not obscure the sun today, and the column will remain very dry, therefore no heavy downpours expected where chances of rain are favorable. Tonight, temperatures will remain just above seasonable, however we will be fairly dry in the low levels so even with skies clearing out fairly decent and weak surface flow it will be hard to develop any fog although some valley fog in the mountains may become apparent. As the tropical disturbance tracks more north chances of rain will remain in the northeast mountains overnight into Monday. && .SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/... As of 200 AM Sunday... For Monday, the sandwich pattern remains with growing chances of rain showers along the mountains and activity out ahead of the frontal boundary to the west. By afternoon, diurnal activity will become a possibility across the entire area. We still remain fairly dry in the upper levels, however there is enough moisture in the low to mid levels along with PWATS up to 1.75 inches and lapse rates above environmental and with high DCAPE values, so there could be some heavy downpours under thunderstorm activity. As for severe potential, we will have weak bulk shear in the teens and enough instability, but with weak upper level support and all the dry air, we will likely just have a hydro threat to localized areas which are flood prone since slow moving storms are likely with only 20kts of steering flow. Temperatures will not change much, however moisture does rise as dewpoints get into the mid 70s at which point locations will be in the advisory criteria range. Guidance did lower temperatures this forecast run, therefore the trend may become to where a heat advisory may not be needed with the 100 degree mark for 2 hours not making it to fruition. We will need to keep an eye on it and re-evalute in the next forecast run. For Tuesday, the focus turns to the cold frontal passage although the front will not make it through the entire forecast area and instead retrograde and become quasi-stationary to our northern periphery. This day will have better chances of activity throughout the entire area and though instability will be high, shear will still be on the weaker side and with no upper level support, it will make it hard for any thunderstorms to become strong to severe and last awhile. Low lapse rates, below the environmental rate, will make it hard to prolong activity although with more moisture and a saturated column along with plenty of DCAPE storms will be able to produce heavy downpours and possibly cause hydro issues where storms move slow. Temperatures will slowly start to decrease starting Tuesday with more rain and cloud coverage and remain so in the next period, however we will still be just above seasonable. && .LONG TERM /WEDNESDAY THROUGH SATURDAY/... As of 200 AM Sunday... The aforementioned quasi-stationary boundary will become stationary but meander slightly about to our north. A wave of low pressure will ride along the boundary and keep it hovering into our region for the remainder of this period. This will allow for more active weather during this period. Mainly looking at active daytimes where most of the thunderstorm potential will be diurnal in nature and then less active nights although low chances of a shower or storms will remain overnight for the remainder of this period. If the boundary does stay just to our north the southern half of our are may be spared much of the time since high pressure will reside there although chances from central blended model guidance has us just as busy as the north, if not busier, along the mountains during the daytime. Accepted central guidance as there is no evidence that it will be less active in the southern half of the area. && .AVIATION /12Z SUNDAY THROUGH THURSDAY/... As of 630 AM Sunday... VFR conditions will dominate through the TAF period. Expect weak southeasterly flow with some possible gusts in the teens by the mid to late afternoon and also some cumulus developing as well although will likely stay few to scattered. Any shower activity should stay along the mountains. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 12Z MONDAY... FORECAST CONFIDENCE: High. ALTERNATE SCENARIOS: None.

Mean temperatures for the month of June 2025 were generally 2 to 4 degrees above normal. This translated into four official NWS Charleston climate locations making the top 10 in terms of their warmest mean June temperatures on record. Precipitation totals varied significantly across the forecast area, with some locations below normal, while others were above normal. Listed below are the locations, ranks, and observed values of the top tens that were set. June 2025 Top Tens Set (Mean Temperature) ------------------------------------------------------------- Location Top 10 Rank Observed Value ------------------------------------------------------------- - Elkins, WV : 2nd Warmest -> 71.6 F - Beckley, WV : 3rd Warmest -> 71.4 F - Clarksburg, WV : 3rd Warmest -> 74.0 F - Huntington, WV : 7th Warmest -> 76.9 F ------------------------------------------------------------- && .RLX WATCHES/WARNINGS/ADVISORIES...
