Short Term. (This evening through Sunday) Issued at 300 PM EDT Sat Oct 23 2021

. Windy Conditions Expected on Sunday .

Cloud cover quickly continues to overspread southern Indiana and central Kentucky this afternoon. Only our far southeast sections remain sunny. Temperatures have been able to warm with most locations reporting in between 60-65 degrees. The cloud cover will likely limit additional heating for the day so highs for the day should top out in the next hour or so. While most will see 60-65, a few spots down along and south of the Cumberland Parkway could top out in the 67-69 range.

For the remainder of the afternoon and into the evening hours, area radars show a band of rain showers pushing into the western part of Kentucky. These showers are on our CWA doorstep and will continue to press eastward. In the near term, the best chances of rainfall will be in areas south of I-64 and west of I-65. By this evening, the showers are expected to scour out a bit with dry conditions returning by late evening. Temperatures will fall back into the 54- 59 degree range this evening.

For the overnight period, a frontal boundary to the south of the region is expected to lift back northward as a warm front. As the warm front pushes northward, the nocturnal low-level jet axis will start to overspread the region. The combination of increasing isentropic lift, and warm advection associated with the low-level jet will result in showers developing across the area late tonight. Model soundings show some elevated instability, so it's likely that a few will hear some thunder with this activity. The best chances precipitation look to be over southern Indiana and the northern half of Kentucky. In fact, portions of southern KY (south of the Cumberland Parkway) may remain fully dry overnight. With the warm advection in place and steady southwest winds, temps will not fall all that much with lows mainly in the 50-55 degree range.

For Sunday, advancing warm front will continue to lift northward and take along the shower activity with it. Convection will likely be ongoing at sunrise across southern IN and portions of northern Kentucky. This activity should continue to trek northward and exit the area by noon or so. After that, some partial clearing may take place. We will be firmly in the warm sector in the afternoon with partly sunny skies. The main weather feature for Sunday will be strong southwest gradient winds. Winds will pick up in the morning and then really pick up in the afternoon with good mixing. Sustained southwest winds of 15-20 MPH with gusts of 30-35 MPH will be possible. Some spots across western KY could see gusts as high as 40 MPH. High temperatures should top out in the low-mid 70s over the Bluegrass with 75-80 for highs in the I-65 corridor and points west.

Long Term. (Sunday night through Saturday) Issued at 254 PM EDT Sat Oct 23 2021

Sunday Night through Monday . A Central Plains upper low will move across the OH Valley with southern Indiana and central KY residing in the warm sector before the attendant cold front sweeps through the region. This system will have a kinematic kick with a 5H jet around 75kt and broad H85 low level jetting of around 55kt across large portions of the TN and OH Valleys. This strong SW fetch will pump copious moisture into the area, albeit within a relatively narrow ribbon along and just ahead of the surface cold front, with PWATs above the 90th percentile of climatological records. As such, model soundings show saturated columns with high shear values. At this point, still expect that the main hazard associated with this system will be strong gusty winds. Instability remains weak though with convection being elevated above low level stable layers. Front should move through the area rather quickly with best timing of FROPA being between 09-15Z for the entire CWA. Monday afternoon should be dry before low level moisture thickens and light drizzle becomes a possibility Monday night.

Tuesday and Wednesday . Upper ridging builds in from the west with surface high pressure riding in from the north resulting in a dry, cool stretch through this period. Temperatures will top out in the upper 50s to low 60s with morning lows dropping into the 40s Tuesday morning and into the upper 30s by Wednesday morning. Will have to watch for frost potential Wednesday morning as skies remain mostly clear with light winds across the area.

Thursday into Next Weekend . Another upper low will deepen as it moves from the Central Plains across the OH/TN Valleys bringing rain chances back to the area. Models begin to diverge a bit during this stretch with GFS/CMC a bit faster with the low than the Euro. GFS/CMC also have the 5H low reaching a nadir of 540dm resulting in a freezing level of around 5kft by Friday. Deepest moisture occurs Thursday when greatest QPF can be expected. As the upper low tracks overhead and to our east Friday and Saturday, expect more stratiform conditions with periods of steady rain and drizzle. Expect highs in the 50s and lows in the 40s.

Aviation. (18Z TAF Issuance) Issued at 132 PM EDT Sat Oct 23 2021

IMPACTS: - Scattered showers this afternoon/eve - Scattered showers and storms late tonight into Sunday morning - Strong southwest gradient winds on Sunday

DISCUSSION:

Mid-high clouds are streaming into the region this afternoon. Cigs will remain above VFR thresholds however. A few scattered showers will be possible mainly at KHNB/KBWG/KSDF. These showers should scour out this evening with VFR conditions continuing. Surface winds will shift the southeast this evening and into the overnight. Later tonight, an additional round of showers and possible thunderstorms will lift northeastward through the region. Current thinking is that this activity would mainly affect KHNB/KSDF and perhaps KLEX through mid-morning Sunday. Sunday afternoon should feature drier conditions with gusty southwest gradient winds. We expect southwest winds of 10-15kts with gusts to 25-28kts.

CONFIDENCE:

Medium confidence on all elements.
