Area Forecast Discussion National Weather Service Duluth MN 1238 AM CDT Tue May 14 2024

KEY MESSAGES

- Dry conditions continue through Wednesday afternoon.

- Frost expected tonight and Tuesday night.

- Multiple chances for showers and storms Wednesday evening onward.

DISCUSSION
Issued at 328 PM CDT Mon May 13 2024

Quiet to begin the forecast with just typical spring weather and normal temperatures. Frosty conditions the next two nights, so issued a Frost Advisory in the MN Arrowhead and NW WI.
Afternoon humidities flirt with fire weather criteria, but winds lack today and tomorrow, when they finally rise, an incoming system will increase moisture leading to little concern.

The system on Wednesday is a run of the mill low pressure with potential for 0.25 to 0.5" of rain. Models start to diverge on timing of any subsequent systems after this small system. Weak forcing makes sense for that so generally timing shortwaves and their impact after this. Blobs of higher PWAT air do make it into the region on Saturday and again on Monday with instability working into the region giving the chance for afternoon showers and thunderstorms.

Not going to get too detailed with the discussion as things are likely to change given the model uncertainty in a weakly forced and unstable air mass despite generally progressive flow.

AVIATION /06Z TAFS THROUGH 06Z WEDNESDAY/
Issued at 1221 AM CDT Tue May 14 2024

VFR conditions for the TAF period. Occasional periods of milky smoke aloft are possible, but should be thinner overall today.
Light winds out of the east/southeast.

Issued at 328 PM CDT Mon May 13 2024
