SHORT TERM. (Issued 405 AM CDT Wed Apr 21 2021)

Today through Thursday:

An upper-level wave will work its way across the Upper Midwest today bringing another day of cooler temps and scattered showers. The set up looks to be similar to yesterday with steep low-level lapse rates, but there looks to be more and deeper moisture along with slightly more instability. Thus, should see more precip make it to the surface. Given the cold airmass and trends from yesterday, precip will mostly be snow especially in the east where the higher moisture is expected, however more of a mix out is likely west where the temps are progged to be slightly warmer. Additionally with the higher instability, cannot rule out some graupel with the more convective showers.

Given a bit more shower activity for today, not expecting much in the way of snow accumulations. Some elevated and or grassy surfaces may see some minor accumulations around a tenth of an inch or two. Although there are some aggressive models hinting at snowfall amounts in the east exceeding a half an inch, we would really need to get some higher snow rates to see these higher accumulations, but still not out of the realm of possibilities. However, impacts from today's showers should be very limited given the spotty nature.

Otherwise, expect showers to diminish through the evening as the trough pushes east and skies begin to clear overnight. This will result in another chilly night with some frost potential into Thursday morning. Thursday is expected to be warmer as upper- level ridging briefly builds across the Upper Midwest. Temps look to warm closer to normal as southerly winds return to southern WI.

LONG TERM. (Issued 405 AM CDT Wed Apr 21 2021)

Thursday Night and Friday:

This period will start out quiet as short wave ridging and subsidence moves across the region. Mid-high level clouds will likely be on the increase Thursday night due to upstream weak warm air advection and mid-level moisture return. The clouds should prevent temperatures from returning to around freezing overnight. Will continue small chances for a few showers on Friday as mid- level moisture continues to increase as well as enhanced weak forcing from compact mid-level short wave passing just to the north of the area during the day. There remains uncertainty regarding how much moisture increases, so at this point the shower chance will remain small. Despite more clouds than sun on Friday, any filtered sunshine and southerly winds will help temperatures warm into the 50s.

Friday Night through Tuesday:

Shower chances will continue Friday night and Saturday as low pressure passes by well to the south, followed by a cold front sweeping through later in the day. Clouds will keep temperatures in check on Saturday, but they should still rise up into the mid to upper 50s during the day. A brief cool down is expected to finish off the weekend, with temperatures flirting with freezing Saturday night. Despite some sunshine on Sunday, temperatures will remain in the 40s closer to the lake, and in the low to mid 50s farther inland. Increasing southerly winds and moisture will start the warmup in earnest on Monday with 60s likely away from the lake. Strong warm advection will bring a period of clouds to the area on Monday, but the low levels look dry at this point, so wl hold off on introducing any showers. Only a few ECMWF EPS ensemble members show precip on Monday. Warm air will continue to surge into the area for Tuesday ahead of strengthening frontal boundary across the central Plains. Low pressure developing along this front will increase the chance for showers and some thunder across southern WI later Tuesday, with better chances on Wednesday.

AVIATION. (Issued 405 AM CDT Wed Apr 21 2021)

Another day of scattered snow showers and/or wintry mix is expected across southern WI. Although VFR conditions will generally prevail through the day, lower MVFR and possibly IFR ceilings will be possible at times with any passing heavier shower. Better shower chances will be closer to the Lake this morning through the afternoon, but chances will diminish this evening. Winds are expected to remain light from the northwest inland while more of an onshore flow is expected closer to Lake Michigan.

Wagner

MARINE. (Issued 405 AM CDT Wed Apr 21 2021)

Fairly quiet marine conditions expected today with scattered rain/snow mix showers and mostly northerly winds. Winds will shift to the west through the evening as a weak pressure trough pushes east. Then looking at more west to southwesterly winds Thursday. Could see a few gusts on Thursday approach small craft conditions but confidence in those stronger winds is low. A stronger front is progged to move through over the weekend with gusts of 20 to 30 kts expected Saturday night through Sunday afternoon.
