Forecast Update. Issued at 940 AM EDT Thu Aug 13 2020
Visibilities have improved enough that the dense fog advisory will be allowed to expire at the top of the hour. Fog/stratus will likely persist for another couple of hours in south-central KY with clearing expected around noon. Rest of forecast remains on track.
Issued at 553 AM EDT Thu Aug 13 2020
Satellite imagery and a few obs are showing more persistent spots of dense fog across southern KY. Skies look to stay mostly clear in that area through sunrise, so expect the visibility restrictions to persist. Therefore, have issued a Special Weather Statement in coordination with OHX. Fog should burn off by 10 AM EDT/9AM CDT
Short Term. (Today and tonight) Issued at 305 AM EDT Thu Aug 13 2020
Today's forecast appears to be following a pretty similar template to what we saw yesterday. The early morning hours should stay mostly dry, with perhaps a few blips on radar across our SW. Otherwise, the main concern this morning will be patchy and transient fog. There have been some instances of locally dense fog across our southern CWA, however given the variable cloudiness don't expect fog to become very widespread or persist in one place very long. Will keep an eye on it.
Otherwise, expect another muggy day as highs top out in the upper 80s to around 90 in the presence of low 70s dew points. Given the weak upper low in the area and perhaps some differential heating due to variable cloudiness, expect to see showers and storms fire once again this afternoon. The best coverage is still supposed to be mainly along and west of the I-65 corridor, and across far southern KY although can't rule out at least an isolated shower or storm anywhere. A very moist atmospheric column will be around generally along and west of I-65 once again, where PWATs should exceed 2" this PM once again. Given the moist column and slow movement of any storms, some locally heavy rainfall amounts will once again be possible. Given moderate instability and little to no shear, don't expect any real organization to storms. However, gusty winds will be possible with stronger storms as we have seen with similar environments.
Overall coverage should diminish later tonight with the loss of heating, however with the upper low in the area and plenty of moisture still can't rule out some isolated to widely scattered activity. Look for mild lows around 70 once again.
Long Term. (Friday through Wednesday) Issued at 300 AM EDT Thu Aug 13 2020
Friday through Sunday Night .
A generally unsettled weather pattern is expected through this portion of the forecast period. Upper level flow will feature a baggy trough axis across the Ohio Valley with a developing ridge over the western US. This upper trough will move slowly through the region Friday and Saturday bringing periods of showers and thunderstorms to the region. Overall coverage should be higher on Friday and Saturday than what we've seen over the past few days. Environmental shear is still forecast to be rather weak, with your run of the mill afternoon instability values. Some of the storms could be on the strong side, but the main threats here will be torrential rainfall, gusty winds, and lightning. PWATs within this airmass will be quite high (>1.8 in). Training of cells could pose some flooding issues in places that see repeated rainfall.
Secondary upper level wave over the Midwest is forecast to drop into the region by Sunday. Associated with this wave, a surface cold front is forecast to push through the region late Sunday. Another round of showers and storms will accompany this front and quickly push through the region.
Highs through the period will generally be in the mid-upper 80s with overnight lows in the upper 60s to the lower 70s.
Monday through Wednesday .
Upper level pattern in this period will be very amplified with a ridge out over the western US and a large/baggy trough over the eastern US. This will place the Ohio Valley in a northwest flow configuration. The main weather story here will be the cooler than normal temperatures and much less humid conditions. Monday will likely be a transition day as the cooler air settles into the region with highs mainly in the low 80s. By Tuesday and Wednesday, highs will generally be in the mid-upper 70s with a few of the urban spots hitting 80. Overnight lows will be quite pleasant and cool with readings mid-upper 50s. A few of the typical cool spots may be able to drop into the low 50s Tuesday and Wednesday mornings.
Aviation. (18Z TAF Issuance) Issued at 101 PM EDT Thu Aug 13 2020
Isolated to scattered showers and thunderstorms have formed this afternoon near a weak boundary across central Kentucky. This activity will likely persist up through sunset before gradually tapering down in coverage. Models hint at overnight showers and storms redeveloping and moving into the region in the 03-06z timeframe and persisting past sunrise tomorrow morning. Confidence in where this may occur is low, and for now will highlight the potential with VCSH wording.
