Area forecast discussion, Apr 7, 6:36 AM EDT, 1 hour 57 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LOUISVILLE KY 636 AM EDT Tue Apr 7 2015 ...Updated Aviation Discussion... .SHORT TERM (Now through Wednesday)... Issued at 257 AM EDT Tue Apr 7 2015 The GFS, 4km NAM, and, to a lesser extent, SPC SREF, have a good handle on an area of showers and embedded thunderstorms moving from southeast Illinois into the lower and middle Ohio Valley at 07Z this morning. The storms are ahead of an upper level disturbance coming in from the lower and middle Mississippi Valley. This convective complex will continue to spread eastward this morning along and a few counties either side of the I-64 corridor. Though the showers and storms will mostly be garden variety, a few gusts of wind or instances of small hail in the strongest cores can't be entirely ruled out. The morning showers and storms will have moved off to the east by early afternoon. This afternoon another weak upper wave will come in from the west. Though some stabilization will occur over southern Indiana and northern Kentucky from the morning rain, additional scattered shower and thunderstorm development will be possible, albeit with less coverage than what we see this morning. Again, a few strong storms will be possible. With plenty of moisture available, locally heavy downpours will be possible with the thunderstorms. The cells should be progressive, but there will be some training this morning in southern Indiana and north central Kentucky. Decided to drop max temps a few degrees in the north where more rain and clouds will prevail through the morning hours, but still have 70s everywhere for highs this afternoon. After a lull this evening, more shower and thunderstorm development will be possible late tonight as the next weak upper wave comes in from the west after midnight. Low temperatures will be in the lower and middle 60s. The relatively low confidence forecast today and tonight becomes even lower on Wednesday. We will remain in the same warm, juicy air mass as today, south of a stationary surface front from Illinois to Ohio. The late night showers/storms tonight will likely persist into Wednesday morning, with redevelopment possible Wednesday afternoon especially near any leftover convective boundaries from the morning activity. Highs should be in the middle and upper 70s...maybe an 80 degree reading if we can get enough sunshine in the afternoon. .LONG TERM (Wednesday Night through Monday)... Issued at 235 AM EDT Tue Apr 7 2015 The focus in the long term period is on thunderstorm chances/timing Wednesday night through Friday. The upper level pattern Wednesday night is expected to feature a digging trough from the Rockies into the central Plains with downstream ridging extending from the Gulf Coast through the southern Great Lakes region. At the surface, a warm and moist air mass characterized by dewpoints in the 60s will be in place thanks to a developing surface low to our west. Stronger southerly flow should make for a mild night with lows only falling into the mid 60s. The focus for thunderstorm initiation Wednesday night is favored to our west where the strengthening low-level jet impinges on an east-west boundary across Illinois. These storms could then take an east/southeast track across portions of the area. Strength/severity a bit more uncertain as elevated instability wanes considerably and effective shear is not as impressive but a few elevated stronger storms would be possible. Kept POPs in the 30-50 percent range, tapered highest to lowest from southern Indiana to southern Kentucky respectively. The main upper level trough will advance eastward Thursday as the surface low deepens/lifts to Wisconsin by Thursday night. 07.00z guidance remained overall similar to earlier runs in its progression, bringing the cold front through the local area late Thursday night into Friday morning. Scattered showers and thunderstorms are possible ahead of the main system though coverage isn't expected to be very high. Decaying strong thunderstorms look to be approaching our western borders during the late evening, and if enough elevated instability remains present, a marginal wind threat exists. Overall, the system looks fairly progressive, limiting the training heavy rainfall threat as well. Ahead of the front, a very warm air mass will be in place. Depending on how cloud cover fares, we'll be approaching 80 degrees in most spots Thursday. A mild night would then set up with lows in the mid 60s to near 70 degrees. Friday looks to be our transition day as the front sweeps across the area. Will keep chance POPs in the morning to early afternoon hours, especially east of I-65 before clearing conditions work in for the evening. Seasonable, pleasant and mostly sunny conditions thanks to surface high pressure expected Saturday into the first part of Sunday. A model consensus approach gives highs in the mid to upper 60s Saturday and upper 60s to low 70s Sunday. Increasing moisture and southerly return flow sets up Sunday night into early next week as the surface high moves to our east. A slow ramp up in POPs, still chance, will be advertised as deterministic models show another system lifting through the central Plains to lower Great Lakes. Seasonable to above seasonable temperatures look reasonable at this time. && .AVIATION (12Z TAF Update)... Updated at 636 AM EDT Tue Apr 7 2015 Showers should be common through the morning hours, especially at LEX and SDF, with some embedded thunder as well. Ceilings will be highly variable, but should prevail MVFR below fuel mins. Expect drier conditions this afternoon and tonight (though scattered showers and storms will still be possible). Ceilings should gradually improve today as the wave that is sparking this morning's convection moves off to the east. BWG could see a few wind gusts into the teens this afternoon outside of convection. Another wave of convection may come in from the northwest late tonight into Wednesday morning, though forecast confidence is not high that far out in this weather regime. && .LMK WATCHES/WARNINGS/ADVISORIES...
