AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LOUISVILLE KY 330 PM EDT Tue Jun 30 2015 .SHORT TERM (Now through Wednesday Night)... Issued at 325 PM EDT Tue Jun 30 2015 The synoptic pattern early this afternoon features northwesterly flow aloft across the Ohio Valley, courtesy of an upstream ridge across the western CONUS. Compact PV anomalies continue to dive through this flow, bringing chances for showers/storms to the region through the short term period. The forecast is unfolding mainly as expected this afternoon. The first concentrated round of storms affected mainly southern KY, which was tied to a compact vort max sliding through the flow aloft. That has now pushed east, so expect any development behind this activity to remain rather isolated given the lack of a focus. Further to the north, convection has blossomed along a boundary associated with a MCV passing through northern Ohio. While some of this activity may brush the far northern Bluegrass, it seems the best cold pool surge is taking place just to the north of Harrison County, KY. 0-3km shear vectors oriented largely west to east support outflow outrunning the southward sagging convection, which is what we are seeing across southwest Ohio and southern IN. The main challenge this evening will be what happens to the northwest. The latest hi-res guidance continues to suggest convection will develop across eastern IL and western IN, which will quickly slide southeast into the Ohio Valley this evening. Latest observations show very little in the way of surface convergence with perhaps a subtle boundary in the area. Therefore, am not highly confident in widespread convective development in this region which will slide into the LMK CWA this evening. Therefore, will cap pops in the 40-50 percent range until storms begin to develop and congeal (if they ever do). If these storms do get going, they could develop a cold pool and slide ESE into the region, bringing a marginal hail threat and an isolated damaging wind threat, but given the late timing, have doubts on how robust any convection will become. Otherwise, convection will dissipate tonight with the loss of daytime heating. May once again see some fog development, but high clouds moving in from the west (and the lingering smoke plume from Canada), may help to limit the density. A MCS will likely develop overnight and push into western KY on Wednesday. Timing has slowed with this system, thus have adjusted pops accordingly. Many hi-res models suggest we could see some thunderstorm development on the cold pool/differential heating boundary of this system Wednesday afternoon. Am not overly high on a severe threat given that mid/high cloud cover will likely be pretty copious limiting instability. Therefore, agree with SPC's marginal risk. On Wednesday night, another MCS is likely to develop across eastern MO and IL, which will push into the Ohio Valley overnight. The latest guidance is pretty impressive with rainfall amounts, thus will be upping QPF amounts. Flash flood guidance is the highest across the southwestern CWA, which is where the heaviest rainfall is expected to fall. That being said, 2 to locally 3 inches will be possible across portions of southern KY, which may lead to some hydro issues. If guidance trends continue, a flash flood watch could be needed. .LONG TERM (Thursday through Tuesday)... Issued at 315 PM EDT Tue Jun 30 2015 Not much change in the extended range with the last several runs of model data. The upper level flow across the CONUS is expected to remain rather amplified with a trough in the eastern US and a ridge out across the west. The Ohio Valley will be situated in a northwest flow regime which will keep the overall weather pattern rather stormy and wet pattern for the remainder of the week. The wet pattern will be driven by a number of mid-level vorticies maxima that will be pushing through in the mean flow aloft. The timing of these features will be key as to when we'll see periods of storms and heavy rainfall. Two emerging signals are becoming apparent within the guidance. First, guidance suggests that the upper trough may shift a bit more southward over the weekend. This would result in the quasi-stationary boundary setting up across southern KY/northern TN. Thus, weekend rains may be more contained across southern KY than across our northern areas. Second, a continuing emerging signal that some mid-level ridging will attempt to work in from the west/southwest by the late weekend and into early next week. However, this would simply push the quasi-stationary boundary more north and stall it across our region, proving yet another environment for more stormy weather. In terms of sensible weather, partly to mostly cloudy skies will be seen throughout the period. Chances are, that we'll probably see less cloudiness in the mornings with more cloudiness in the afternoon. Rounds of showers and storms will be possible throughout the period with the passage of mid-level vorticity maxima coming through. The first of these look to push through very early in the period (Wed Night/Thursday). Second wave looks to push through Friday night and Saturday. However, the further south shift of the aforementioned frontal boundary may result in the heavy rains/storms being more concentrated down across the TN Valley. More diurnally driven convection will likely occur Sunday through Tuesday. Greatest concentration will be across the south late in the weekend with the concentration pulling northward early next week. Temperatures will remain below seasonal normals throughout the period due to expected cloud cover and associated precipitation. Generally, highs will likely run in the lower to middle 80s with overnight lows in the upper 60s to around 70. A moderation of temperatures looks likely late in the weekend and into early next week as the boundary pushes back to the north. Mid-upper 80s may envelope the region by then. Rainfall amounts over the next seven days will be fairly impressive. Depending on where the boundary actually sets up, an axis of heavy QPF will be possible. Our current forecast keeps the heaviest axis of QPF across our west and southwest. Widespread 2-4 inches rainfall amounts look likely across our region, with locally higher amounts possible across the south/southwest sections. && .AVIATION (18Z TAF Update)... Issued at 118 PM EDT Tue Jun 30 2015 Thunderstorms will continue to develop this afternoon in a couple of different areas. As it stands now, KLEX and KSDF have the best chance of seeing thunderstorm activity push in from the north later this afternoon into early this evening. There stands a bit less of a chance at KBWG where storms have fired and already pushed to the east. In any storm that affects a site, winds will be gusty along with brief vsby reductions into the IFR range. Otherwise, convection will come to an end tonight. There will once again be a chance of some light fog at KBWG and/or KLEX, but some incoming clouds from the west may help to limit the fog threat. Will introduce MVFR vsbys for now. Otherwise, renewed chances for showers and storms look to arrive toward the end of the valid TAF period as yet another system pushes in from the west. && .LMK WATCHES/WARNINGS/ADVISORIES...
