.DISCUSSION...
Issued at 238 AM EDT Thu May 30 2024

High amplitude/short wavelength ridge will bring a welcome, albeit
brief, return to dry/quiet weather today and Friday. There is one
last trough rotating through the Lower Great Lakes today but
northerly flow has advected a much drier and more stable airmass
into the region and no precip is expected. Even clouds will be
difficult in this airmass and expect mostly sunny skies to add a few
degrees to afternoon highs compared to yesterday, particularly in the
NW. Winds remain light and variable through tonight with mostly
clear skies yielding lows in the 40s once again. Ridge axis passes
to our east on Friday and winds slowly become more southerly with
some weak WAA. This will push highs into the mid/upper 70s on Fri.

Another weak southern stream wave will eject into the Ohio Valley on
Sat and bring our next chance for rain. Moderate CVA and moisture
advection on a 50 kt LLJ will support numerous showers and a few
embedded thunderstorms. Warm temps aloft and early arrival of
clouds/prefrontal precip will substantially limit the instability
though and severe storms are not currently expected. Forecast
confidence decreases heading into next week as sensible weather will
be driven by small-scale features difficult to resolve this far out.
Suspect Sunday will end up primarily dry though still plenty of
ensemble guidance to support chance PoP`s. Forecast will trend
warmer through the middle of next week as broad ridging develops
over the eastern CONUS.
