SHORT TERM. (This evening through Thursday) Issued at 222 PM CDT Wed Apr 14 2021

At 130 PM, sprinkles/isolated very light showers were found across the area as the upper level low which has dominated the local weather over the last couple of days continued to swirl over northeast Wisconsin. Abundant cloud cover and cold air aloft made for widespread temperatures in the mid 30s to lower 40s.

Short-term guidance continues to suggest an uptick in isolated shower chances for the rest of the afternoon with minor diurnal heating and shortwave energy rotating around this low into our area. Couldn't rule out a few snowflakes as well where temperatures have yet to reach the upper 30s. Precipitation chances slowly wane tonight as daytime heating is lost and the upper low continues to crawl east, although some residual saturation in the soundings suggests some light drizzle or flurries could linger. Cloud cover looks to hang tough overnight given extensive stratus layer upstream, but we could begin to see some breaks open up by Thursday afternoon as weak ridging builds in and the upper low moves farther east toward Lake Erie. Lows tonight will fall back into the 30s, but highs Thursday will be a bit warmer than today, in the 40s to near 50, as the chilly air aloft begins to moderate slightly.

LONG TERM. (Thursday night through Wednesday) Issued at 222 PM CDT Wed Apr 14 2021

From Thursday night into Friday, a shortwave ridge will move east across the area. This ridge of high pressure will provide partly cloudy skies. Temperatures will be close to normal.

From Friday night into Saturday night, a southern stream shortwave trough will move south of the region. This system may produce a few showers south of Interstate 90. Like Friday, temperatures will be close to normal.

From Sunday night into Monday, a northern stream shortwave trough will move southeast through the region. This system looks like it will bring widespread light rain to the area. In the wake of this system, much colder air will move into the region. High temperatures will be in the upper 40s and lower 50s on Monday and in the lower and mid-40s on Tuesday. These temperatures are close to the NBM's 50th percentile. There are even indications in the ensembles that these temperatures may not be cold enough yet, but with large model spreads the confidence was not there to do that.

AVIATION. (For the 06Z TAFS through 06Z Thursday night) Issued at 1048 PM CDT Wed Apr 14 2021

Stubborn pattern continues to plague the aviation weather across the region with closed upper low over the Great Lakes. Some breaks in the lower ceilings has led to pockets of VFR conditions but unsure how long this will last. Tended to keep ceilings in at least into Thursday until ridging gradually starts and some hints at short term guidance of slightly drier air mixing in. This trend might lead to less and less persistent cloud cover, albeit probably a slow transition. Kept idea of more breaks in overcast late in forecast with a hope for more widespread VFR.
