KEY MESSAGES

- Dry and cool this weekend with frost possible Sunday and Monday morning.

DISCUSSION
Issued at 239 AM EDT Sat Apr 20 2024

Weak cold front dropping through the lakes attm and will drive another push of chilly air south today. Even with sunshine and diurnal heating, temp recovery this aftn will be tempered with highs for most locations sub 50 and wind chilly to boot as w/nw winds gust 25 to 30.

Cold low level thermal trough tonight in conjunction with upstream moisture likely to yield considerable stratocu through nw zones with some moisture flux off lake Michigan likely. This throws a wrench into otherwise slam dunk frost potential and general surrounding consensus this morning was to punt headline decision to dayshift.
Nevertheless retained frost mention north through eastern zones as clearing possible prior to sunrise Sun.

Thereafter brief moderation as ne CONUS height field temporarily flattens ahead of another vigorous nrn stream wave digging through the lakes Tue. Limited moisture return in advance of this sys offset by good frontal dynamics looks to limit any thunder potential Tue aftn/eve to isold at best with showers given. More erstwhile warmup expected by dy7 (Fri) and beyond as sw flow deepens across the ern US in response to potent longwave trough through the wrn US.
