AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LOUISVILLE KY 254 PM EDT Sun May 10 2015 .SHORT TERM (Now through Monday Night)... Issued at 250 PM EDT Sun May 10 2015 Main forecast concern for the short term period is severe storm potential tomorrow afternoon/evening. This afternoon, surface analysis showed weak high pressure across central/eastern Kentucky. Upper level ridging lies overhead, in between tropical depression Ana and a strong shortwave trough across the central Plains. Locally, scattered clouds with south/southeast flow and temperatures in the 80s prevailed. For this evening and the overnight, main upper level impulses will generally ride northwest of the forecast area and overall a dry forecast is anticipated. Latest meso-models take the complex of storms across Missouri through Illinois and portions of Indiana overnight, which could brush portions of southern Indiana after midnight. Maintained 20 to 30 percent chance POPs there, otherwise look for dry conditions. A warm, muggy night is on tap with lows in the mid 60s to near 70. Severe storm setup/thinking for Monday hasn't changed too much from previous forecast as focus for storm initiation is expected to be a pre-frontal trough during the mid afternoon, then depending on timing and destabilization, as the main cold front arrives later in the evening. Overall timing threat looks to be mid afternoon to mid evening. Model solutions do vary in strength and details, the NAM exhibited a more favorable setup while the GFS/ECMWF was more muted. Daytime heating and weak/moderate mid level lapse rates yield between 1000 and 1500 J/kg of CAPE across the region in the presence of a largely parallel shear environment. The majority of the shear lies in the lowest 3 km, values around 40 kts, which supports bowing/line segments. The greater dynamics with this system will pass the area to the northwest, closer to the surface low, but there could be a sufficient amount to generate strong to severe storms. The main threat is damaging winds but large hail remains possible as well. Finally, a look at the hi-res meso models, the NSSL and SPC WRF do show a broken north-south line of storms arriving in our western areas by mid afternoon. Showers/storms will end west to east during the evening hours as the front sweeps through. Slightly drier and cooler air arrives by early Tuesday morning. Lows 55-62. .LONG TERM (Tuesday through Sunday)... Issued at 250 PM EDT Sun May 10 2015 Tuesday - Thursday... The mid week forecast looks quite pleasant in the wake of the cold front passage Monday. Temperatures will drop back closer to climatological normals for this time of year. Expect dry, mostly sunny to partly cloudy days Tues/Wed/Thu with highs in the 70s and lows in the upper 40s/lower 50s. Friday - Sunday... An active weather pattern looks to return to the Ohio Valley by the end of the week and through the weekend. An upper level ridge axis will move into the region Thurs with a broad trough over the western coast. The ridge looks to be weak enough for multiple upper level waves originating from the western CONUS trough to work their way eastward through the Ohio Valley starting Thurs night through Saturday. Did increase POPs for Thurs night as the 12z GFS/GEM/GFS ensembles bring the first shortwave in a little earlier. The ECMWF seems to be a consistent outlier on a slower, weaker solution with this initial wave. All long range models agree that multiple hard to time waves look to continue along the periphery of the ridge through the weekend. Although no organized threat for severe weather looks imminent for this Fri-Sun. Strong storms will be possible in this setup. Also, heavy rainfall could become a concern as well. However, the heaviest rainfall axis through the next week still looks be mainly focused in TX. Temperatures will increase this weekend as the ridge axis sharpens and thicknesses increase. By Sat/Sun, highs will be back into the 80s with lows in the 60s. && .AVIATION (18Z TAF Update)... Updated at 1245 PM EDT Sun May 10 2015 Mid-level subsidence and ridging will keep thunderstorm potential to a minimum this afternoon and evening. Could not rule out a stray shower or storm but for now, will leave a mention out of the TAF. Baggy flow overnight and increasing moisture could result in some light fog, especially at BWG. For Monday, plan on increasing southerly winds with some gusts 20-25 kts possible by afternoon. Greater chances for showers/storms and possibly flight restrictions comes after 18z Monday...more likely toward 21z or 00z.
