Spot Forecast for KDFWR Stowe Learn & Burn...KDFWR
National Weather Service Louisville KY
850 AM EDT Thu Apr 25 2024

Forecast is based on ignition time of 1400 EDT on April 25.
If conditions become unrepresentative...contact the National Weather
Service.

.DISCUSSION...Nearby high pressure to the north will result in mostly
sunny skies today but light winds and poor smoke dispersion. Despite
the weaker flow, the boundary layer will mix out fairly well as
mixing heights climb to over 4000 feet at the prescribed burn site.
Afternoon minimum relative humidities will likely fall below 30%,
though if we end up a little warmer than forecast this number
could be lower.

By Friday, scattered showers and perhaps a very isolated storm
could move through the region ahead of a warm front. The weekend
will feature warm temperatures and breezy conditions.
