.DISCUSSION...
Issued at 158 PM EDT Thu May 22 2025

The overall upper level flow will remain NW or W into the weekend,
with any meaningful moisture and warmer air pushed well south of the
area. This will allow for a much more tranquil weather pattern into
the upcoming holiday weekend. In the near term, skies are slowly
clearing from the NW as drier air pushes in, but a lingering pocket
of colder air aloft will allow cu to pop in those areas prior to
sunset. Thereafter, skies will clear even more and winds slowly
diminish. Overnight lows in the NE may dip into the upper 30s,
partially dependent on just how fast the last of the clouds depart
from that area. As mentioned in the overnight discussion, winds
should remain just high enough to limit any frost potential. Frost
could possibly be a bit more of a concern Sat morning across
northern areas if winds decouple sufficiently. Despite what should
end up being a decent amount of sun and a overall nice weekend,
temperatures will be a fair amount below normal (mid 70s) with highs
in the upper 50s to mid 60s.

Although no large systems are in view, a weak trough will move into
the SW US Friday and deepen somewhat as it works slowly east. Models
continue to vary on handling of this feature including the track,
strength and precip potential. Slgt chc to chc pops will remain in
place Monday into Tuesday. Although the forecast does have us
returning closer to normal by Thursday, concerned that the overall
chaotic upper level flow and multiple disturbances may keep the
warmest air at bay.

.AVIATION /00Z TAFS THROUGH 00Z FRIDAY/...

Diurnally-driven breezy northwest winds will subside this
evening after sunset. As an upper low moves east out of the
Great Lakes region and high pressure builds across the Midwest,
skies will clear tonight and winds will become lighter. Friday,
expect VFR ceilings to persist the entire day with winds
increasing once again during the daytime hours. Northwest winds
will gust as high as 25 kts Friday afternoon/evening.
