Short Term. (This evening through Wednesday) Issued at 300 PM EDT Tue Mar 31 2020
Area of surface low pressure continues to move eastward across eastern AL and into GA this afternoon. KY is on the far northern side of the rain shield and we've seen a nice deformation band set up from Bowling Green to Frankfort. We are seeing a little more enhancement just east of Louisville across portions of Nelson/Spencer/Washington/Anderson counties. This deformation band is expected to pivot east and southeastward over the next few hours. Mid-afternoon temperatures ranged from the low-mid 40s over the Bluegrass region to the upper 40s/lower 50s in areas west of I-65 where it has been drier. Not expecting much rise in temps in the next few hours.
For this evening, we expect the deformation band of light rainfall to continue to move east/southeast and it should clear our county warning area by mid-late evening. Can't rule out some lingering drizzle into the wee hours over in the I-75 corridor. Clouds are probably going to hold on for a while (longer than the models suggest) so we plan on going cloudy for much of the night east of the I-65 corridor. Some partial clearing may make it as far east as the Natcher Parkway. Lows tonight should drop into the upper 30s in most locations.
For Wednesday, high pressure is expected to nose in from the west and we'll start to see heights aloft build slowly. We're likely to start off the day with partly to mostly cloudy skies. However, we should see some partial clearing by mid-late afternoon. Highs look to top out in the upper 50s west of I-65. However, in the east, temperatures may only top out in the upper 40s to the lower 50s depending on how long cloud cover sticks around.
Long Term. (Wednesday night through Tuesday) Issued at 248 PM EDT Tue Mar 31 2020
Thursday and Friday . Upper level ridging will build meridionally across the MS Valley and into Canada, which will slow the progress of a SW Canadian closed low as it sends small shortwave perturbations through the longwave pattern. This will result in a cloudy period with virga likely falling from thickening mid cloud. Thursday will see light northerly winds and relatively cooler temperatures with lows in the mid to upper 30s and highs in the low to mid 60s. Winds will veer becoming more southerly by Friday morning resulting in low level WAA as min temps remain in the 40s and highs climb into the upper 60s with some 70s across our south.
Saturday and Sunday . A stronger shortwave will swing around the SW Canadian parent low, which will flatten out the upper ridge allowing for a surface low over MN/SW Ontario to drag a cold front through the region over the weekend. Moisture will be limited with this system with PWATs less than an inch so only expecting light rain showers with maybe a rumble of embedded thunder in our southern counties. Rain should taper off by Sunday afternoon. Southerly flow ahead of the front will see an increase in daily temps with morning mins in the upper 40s to low 50s and afternoon highs in the low 70s.
Monday and beyond . Brief high pressure will see dry conditions until the next round of small shortwaves bring light rain chances back to the region. Much disagreement between models exists at this time, but soundings suggest chance of showers with some thunder possible. Gradual warming will continue as max temps slowly climb higher into the 70s both Monday and Tuesday.
Aviation. (18Z TAF Issuance) Issued at 114 PM EDT Tue Mar 31 2020
Afternoon surface analysis reveals an area of surface low pressure down near Birmingham, AL. This feature will move off to the east this afternoon. To the north of the system, Kentucky will be on the northern edge of the precipitation shield. Area radars suggest that we may be starting to see a bit of a deformation band set up across the state, mainly from Bowling Green northeast to Lexington. Cigs at KLEX/KBWG are likely to bounce around the fuel-alternate threshold this afternoon with visibilities running between 4-6SM due to light rain. Further north/west, at KSDF/KHNB, dry conditions are expected with cigs running in the high end of the MVFR range at KSDF with mainly VFR at KHNB. Rain showers at KBWG and KLEX are expected to diminish by evening but widespread low cloudiness will stick around through the evening with winds shifting to the northwest at 4- 8 knots.
For the overnight period, ceilings are likely to drop back down to between 1500-2500 ft AGL after midnight and continue through Wednesday morning. Some improvement to MVFR and possibly VFR looks likely by late Wednesday afternoon.

Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.
