549 FXUS64 KOHX 110159 AAA AFDOHX Area Forecast Discussion...UPDATED National Weather Service Nashville TN 859 PM CDT Mon Jun 10 2024 ...New UPDATE... .UPDATE... Issued at 859 PM CDT Mon Jun 10 2024 Tweaked hourly gridded temperature, dewpoint, wind direction/speed grids blending them with previously forecasted late evening hourly gridded values. Current regional temperature trends continuing to support forecasted overnight low values. 11/00Z KOHX Sounding profile depicting moisture supporting a continuance of a few CU as these early evening hours progress but a continuance of a stable atmosphere in place as low level atmospheric ridging influences along with dry northwesterly upper level flow prevails. Remainder of forecast continues to be on track. && .SHORT TERM... (Rest of today through Tuesday Night) Issued at 1115 AM CDT Mon Jun 10 2024 After a foggy start to the morning, the area is clear with pleasant temperatures for this time of year. Highs this afternoon will top out in the mid 70s to lower 80s. There is a dry surface front currently in southern Illinois through the Ohio River Valley that is diving south. This will bring a slightly cooler and drier air mass into our area for tonight and tomorrow. Lows tonight will be in the low to mid 50s with even a couple spots touching the upper 40s on the Upper Cumberland Plateau. There could be a few patches of fog near dawn but dew point spreads are slightly higher than this morning and the HREF is showing only a few patches of decreased visibilities. Expect more clear skies and northerly winds tomorrow as surface high pressure slides by the area to the north. We will have one more cool night Tuesday night with temperatures in the 50s before we start the summer warm up. && .LONG TERM... (Wednesday through next Monday) Issued at 1115 AM CDT Mon Jun 10 2024 Temperatures will begin an upward trend on Wednesday with highs in the low to mid 80s, but the first noticeable difference will be on Thursday with a large part of the area getting to 90 or above as upper ridging influences start spreading eastward into Tennessee. The ridging influences will only get stronger on Friday as it moves eastward. By Saturday afternoon the upper high will be parked over Middle Tennessee. Highs in the mid 90s Friday through Sunday look reasonable. In addition to the increase in temperatures, dew points will slowly climb from Thursday into the weekend. By Sunday the center of the upper high will be east of the area with some weak southerly flow increasing moisture. Some heat index values Sunday afternoon could touch 100 degrees. As far as rain chances, the best we are looking at is some isolated activity on Sunday, but not all of the guidance agrees that will happen. && .AVIATION... (00Z TAFS) Issued at 621 PM CDT Mon Jun 10 2024 VFR conditions continue this cycle. A pressure gradient is causing winds to gust near 20 kts.
