Area Forecast Discussion National Weather Service Nashville TN 613 AM CDT Fri Apr 16 2021

UPDATE. FOR 12Z AVIATION DISCUSSION.

DISCUSSION.

Eyes have been on the Upper Cumberland over the last couple hours to see how fast temperatures will drop. Dew points are around freezing with temperatures in the low to mid 40s at this point. Some scattered cirrus are showing up on satellite imagery with thicker cirrus to the south and west. I still expect we'll see some patchy frost around dawn, but a widespread frost looks unlikely. Temperatures today will rebound into the low to mid 60s as weak upper ridging quickly slides through the area ahead of a weak, flattening upper trough. There will be enough moisture with this system for some scattered light showers after midnight through Saturday morning.

Another weak upper trough will clip the area late Sunday afternoon/evening with a chance of a couple light showers. Areas along the TN/KY border have the best chance of seeing anything with this trough. Upper flow remains quasi zonal going into next week. Monday and Tuesday look dry before a slightly stronger trough quickly traverses the area Tuesday night with some scattered showers. Behind this trough, rather cool temperatures will settle into the area with highs on Wednesday in the 50s to lower 60s. Wednesday night looks like a decent opportunity for frost particularly along the Upper Cumberland. With the current pattern of weak troughs and below average temperatures, our severe weather chances look very slim over the next 7-10 days.

AVIATION. 12Z TAF DISCUSSION.

VFR. Light and variable winds expected today, with predominant wind direction out of the northeast. Chances for rain still look to move in from the southwest later tonight, with scattered showers possible after 09Z at KBNA/KMQY/KCKV.

OHX WATCHES/WARNINGS/ADVISORIES. Frost Advisory until 8 AM CDT this morning for Cumberland- Fentress-Pickett.
