Short Term. (This evening through Monday) Issued at 310 PM EST Sun Mar 7 2021
Afternoon satellite imagery shows clear skies across the region with plenty of sunshine. Temperatures were still cool across the Bluegrass region with readings generally in the upper 40s with low- mid 50s over the I-65 corridor. Warmest readings were out toward the Natcher Parkway area with mid-upper 50s. A very sharp dewpoint gradient was noted across the region. Dewpoints were in the lower teens across the Bluegrass region while dewpoints were in the upper 20s along and west of I-65. The low dewpoints out in the Bluegrass region are producing low relative humidity values which could be conductive for a quick spread of any wild fire or prescribed burn. So we issued an Special Weather Statement to highlight this through sunset. For the remainder of the afternoon, no significant weather is expected and temperatures will start to fall this evening after sunset into the upper 30s and lower 40s. Areas east of I-65 could be near freezing by midnight with good radiational cooling expected.
Overnight, quiet and tranquil weather is expected with lows in the mid-upper 20s over the east (I-75 corridor) and lower 30s in the I- 65 corridor and points west.
Sunny and milder weather is expected for Monday. NBM blend is too cool here and so have gone with intra-office coordination and will be using the 75th percentile NBM numbers (the regular blend is 50th percentile). Highs tomorrow will range from the lower 60s in the Bluegrass with mid-upper 60s in the remainder of the area.
Long Term. (Monday night through Sunday) Issued at 255 PM EST Sun Mar 7 2021
By Monday evening, sfc high pressure will be situated over the Great Smoky Mountains, influencing return flow into the Ohio Valley. An upper ridge and this sfc high will remain situated over the southeastern CONUS for Tuesday and Wednesday, helping to usher in warmer temps and quite possibly overachieve NBM forecast temps. Due to this deep and persistent SSW flow, max temps were bumped up for Tuesday-Friday. NBM Max T solution is well too cool for this set up (below the 25th percentile), so bumped temps up to the 50th-75th percentile of the guidance spectrum. This brings temps into the neighborhood of the upper 60s for Tue/Wed. Thursday could be the warmest day of the period, with temps possibly reaching the low 70s as stronger southerly sfc winds and a SW LLJ works overhead east of a cold front boundary. After collaborating with neighboring WFOs, will be bumping winds up from NBM as well for Wed-Fri.
On Wednesday, a shortwave and sfc low will track from the Plains northeast towards the Great Lakes. It will trail a cold front across the Midwest. By late Wednesday night, the cold front should be extending from the Great Lakes down to Texas, with a secondary sfc low located somewhere over TX/KS. Low PoPs arrive in our southern IN counties late Wednesday night as precip could extend well ahead of the actual frontal boundary. Best precip chances remain to our north, but will keep some PoPs in for the northern half of the CWA to account for any sway in the precip axis and frontal boundary. The boundary should sag south enough to intrude our southern IN counties by Friday.
Guidance diverges by Friday afternoon, with the Euro slowly sagging that cold front into the region and keeping it around through the weekend. In contrast, the GFS keeps the frontal boundary just to the north of the Ohio River, and eventually lifts it back north as it brings another sfc low/cold front out of the Plains and into the Ohio Valley. Will continue to monitor model trends in the coming days.
Aviation. (00Z TAF Issuance) Issued at 530 PM EST Sun Mar 7 2021
Strong, slow high pressure will continue our tranquil weather with VFR flying conditions. Light and variable breezes tonight will increase to around 10kt as they come in from the southwest during the daylight hours Monday as the center of the high sits over the southern Appalachians.
