.DISCUSSION...
Issued at 240 AM EDT Mon May 5 2025

Areas of light rain will continue through Tuesday as the upper low
persists over the region. The low was near the Ohio River and
was nearly stationary early this morning. The low will gradually
come in phase with an upper level system to the north. The track
of the ejecting surface low across Ohio will bring one last
round of deformation type of precipitation into the forecast
area. Model trends and WPC forecasts favor the precipitation
axis along the Indiana and Ohio border. Maximum rainfall amounts
could locally exceed 1.50".

The upper low will eject out of the region and will be replaced
by upper level ridging. The upper level ridge will very gradually
build into the region causing temperatures to rise much above
normal by early next week. High temperatures Monday should be
close to 80. This new pattern will be anomalously dry and will
keep dry weather past next week Monday.

.AVIATION /18Z TAFS THROUGH 18Z TUESDAY/...
Issued at 134 PM EDT Mon May 5 2025

Low clouds have mixed out for the time being with peeks of
sunshine and cold air aloft likely to allow for some shower
redevelopment through 00Z mainly impacting KFWA. Have backed off
on coverage somewhat using a tempo vs predominate group.
Thereafter the pesky upper low and associated sfc reflection
will track slowly northeast, reaching KTOL by 12Z Tue. Yet
another band of showers will take shape this evening and persist
into Tuesday on the north and west side of the low. KFWA should
see the greatest impact again requiring an extended period of
MVFR conditions (maybe some visits with IFR at times by Tuesday
morning). KSBN may remain on the outskirts of this activity so
for the moment have maintained the prob30 in the 8 to 12Z time
frame. Conditions should begin to improve once again near and
beyond the end of the period.
