AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LOUISVILLE KY 324 AM EDT Sat May 10 2014 .SHORT TERM (Now through Sunday)... Issued at 300 AM EDT Sat May 9 2014 The synoptic pattern early this morning features a strong trough pushing through the Upper Great Lakes. An associated surface low was centered across across southern Canada, with a surface cold front extending southwest through northern Indiana/Illinois/Missouri. This front will slowly drift east today as it washes out and lifts north on Sunday. Convection continues early this morning across portions of western and central KY. This convection is being forced by a low-level jet impinging on a remnant outflow boundary from convection last evening. This activity will likely continue through the morning hours today, perhaps even expanding more in coverage as synoptic-scale forcing associated with another ejecting PV anomaly crosses the region. The best coverage looks to be across southern KY northeast into the Northern Bluegrass region. Southern Indiana will likely see the least amount of activity this morning. The main threats with these storms will be heavy rainfall and some small hail. In fact, will need to watch portions of southern KY closely over the next few hours for some localized flooding potential as storms continually train over the same areas (especially Logan/Butler counties). By late this morning into the afternoon, the main PV anomaly will push northeast of the region. The main synoptic cold front will quickly wash out across southern IN and northern KY this afternoon as it becomes parallel to the upper-level flow (which will be transitioning to more zonal). Therefore, with subsidence in the mid-levels and no strongly convergent feature at the surface, think additional development late this afternoon will be hard to come by. While a stray shower/storm cannot be ruled out (especially across southern IN or northern KY near the front), don't think it's worth a mention in the forecast. Therefore, have gone dry by late this afternoon into this evening across much of the region. Clouds will likely linger across east-central KY through a good part of the day keeping highs in the mid 70s, but sunshine should break out across southern IN and west-central KY, which should help temps climb into the upper 70s and lower 80s. Guidance continues to weakly hint at some sort of an MCS developing across the Central Plains today, approaching the Ohio Valley overnight. It appears that the main low-level jet axis will be focused to the northwest of the region. Additionally, the flow will be starting to amplify with heights building across the region. Therefore, am not sold that this system will make it this far, and have lowered pops from previous forecast. Will still leave some slights in across the far northern CWA, but think most will stay dry Saturday night into early Sunday. Overnight lows will be in the low to mid 60s. Mother's Day is shaping out to be quite nice across the region. What's left of the pesky, washed-out front will begin to lift north in response to an approaching upper-level trough. This front along with some weak isentropic ascent may be enough to spark an isolated shower/storm mainly north of I-64, but again this chance appears quite slim. Think most will stay dry with partly to mostly cloudy skies. Highs will be rather warm as thicknesses increase through the day and we mix efficiently due to solid southwest flow. This should push highs into the middle 80s across most areas. .LONG TERM (Sunday night through Friday)... Issued at 323 AM EDT Sat May 10 2014 An active period of weather looks likely for a good portion of the extended period...especially in the middle part of the work week. Tonight's guidance still has inconsistencies among the various long term model solutions. However, a clear emerging trend in the data shows a much slower progression of a strong mid-upper level wave crossing the country early next week. With this trend, it appears that the beginning of the forecast period will be a bit drier and warmer than normal. As this trough axis passes through the region, we expect to see ample rainfall with the associated cold frontal passage along with a sharp cooling trend that looks to continue into late next week. With the slower progression of the upper level wave expected, we expect drier and warmer conditions Sunday night through Monday night. In general, we have backed off PoPs considerably for Sunday night and much of the day on Monday. A continued southwesterly fetch will bring more moisture and warmer air into the region. While no real trigger exists for convective initiation, it does appear that diurnal/differential heating will likely produce isolated-scattered convection during the afternoon hours with convection dying off in the evening. Lows Monday morning will be quite mild with readings generally in the middle to upper 60s. Highs Monday look to warm into the middle to upper 80s. Lows Tuesday morning will be similar to Monday morning with readings in the middle to upper 60s. The upper trough axis will start to work into the region on Tuesday with a cold front approaching from the northwest. This will mark the start of a very unsettled period of weather for the Ohio Valley. We should see a band of convection develop out to the west of the area and then slowly work into the region Tuesday afternoon and evening. The boundary will likely stall out across the Ohio Valley on Wednesday as a secondary wave rounds the base of the trough and helps develop cyclogenesis across the lower Mississippi Valley. This low will ride up along stalled out front Wednesday night into Thursday. As this low passes northeast of the region, much cooler air will rush into the area. With this thinking, have increased the PoPs considerably from Tuesday afternoon through Wednesday night. Temperatures on Tuesday will likely warm into the middle 80s once again with highs on Wednesday only warming into the lower to middle 70s. By Thursday, the anomalous upper trough axis will push through the region. We expect to see unsettled weather continue, though thunderstorms will likely be much more limited with mainly rain showers being the primary weather threat. It will be distinctly cooler with highs only warming into the 60s. Have gone well below guidance here as the statistical guidance is likely going to play catch up during the week. The upper trough axis should clear the region by Friday, but a deep cyclonic flow pattern looks to remain over the Ohio Valley by late week and continue through next weekend. This will result in much much cooler conditions across the region. Latest guidance suggests highs in the upper 50s to the lower 60s by Friday...with overnight lows in the 40s. && .AVIATION (06Z TAF Update)... Issued at 107 AM EDT Sat May 10 2014 A rather complex TAF forecast is in store, as several boundaries from earlier convection are currently sparking convection. Over the next couple of hours, convection should remain scattered in nature. However, there is a subtle signal in guidance that convection will increase before dawn as another shortwave trough ejects north into the region. The best coverage of this precip looks to be across KBWG and KLEX. KSDF looks to remain on the northern edge of the better coverage of showers and embedded thunderstorms, but certainly they cannot be ruled out at any time overnight into Saturday morning. MVFR ceilings will likely move into all terminals overnight, especially as the steadier precipitation pushes in just before dawn. After more widespread coverage of showers/storms Saturday morning, they should become more isolated in nature by the afternoon hours. Winds will be out of the SSW at 10-15 knots. && .LMK WATCHES/WARNINGS/ADVISORIES... KY...NONE. IN...NONE. && Short Term........KJD Long Term.........MJ Aviation..........KJD
