Area Forecast Discussion National Weather Service Green Bay WI 334 AM CDT Wed Apr 1 2020

Forecast discussion for routine morning forecast issuance

SHORT TERM. Today . Tonight . and Thursday Issued at 333 AM CDT Wed Apr 1 2020

A weak but coupled upper jet was helping to produce some light precipitation in far northeast Wisconsin at 08UTC. Temperatures at the surface and aloft suggest that this will be very light rain or sprinkles, though isolated very light snow or freezing drizzle are possible. This feature will move east today as weak upper ridging approaches from the Plains. Highs today should be around 5 degrees higher than yesterday due to partial clearing and weak warm advection.

Lows tonight should be lowest in northeast Wisconsin where skies have the best chance of being clear. Lows will be 3 to 5 degrees above normal.

Thursday should be partly sunny and mild, with highs in the low to mid 50s, except much cooler near the bay and lake. Some light rain cold arrive late in the afternoon in northcentral Wisconsin.

LONG TERM. Thursday Night Through Tuesday Issued at 333 AM CDT Wed Apr 1 2020

Forecast challenges mainly revolve around timing precip chances across the area. Models have come into better agreement with the timing of a slow frontal passage on Friday into Saturday. Then details get more murky late in the weekend into early next week when southwest flow briefly becomes established, and timing shortwave impulses gets tricky. Prefer to transition from the operational models to the ensemble means by early next week.

Thursday night through Friday night . A cold front will be slowly moving across Minnesota to the Wisconsin border on Thursday night. Although the gfs is more ambitious in creating precip over north- central WI, the nam and ecmwf are less so, as they show the primary moisture channel and mid-level fgen remaining along and behind the front well west of the region. Forecast soundings also show deep saturation will struggle to be achieved at times through the night. Will therefore slow down the forward progression of precip chances. Chances of precip, however, remain expected to increase on Friday when the front moves into north-central WI. Eastern WI will likely see the best chance of precip on Friday night. Precip amounts should diminish as the front moves east as the upper support weakens. Rainfall amounts of around 0.25 inch still look possible.

Rest of the forecast . As the front exits to the east, chances of precip will end on Saturday morning over eastern WI. Then a very dry airmass within a high pressure system will push across the region for the second half of Saturday into Sunday night. Because the airmass will be so dry (pwats under 0.25 inches) think models (particularly the gfs) are too ambitious in returning precip chances on Sunday night, and prefer the slower solutions of the ecmwf/canadian. But by Sunday night into Monday, strengthening warm/moist advection should lead to increasing chances of light rain. A more potent system could also arrive in the Tuesday into early Wednesday time period.

AVIATION. for 06Z TAF Issuance Issued at 1044 PM CDT Tue Mar 31 2020

Low clouds are expected to remain widespread across the area into tomorrow, with some clearing possible late in the day as drier air finally circulates into the area from the east. Bases will edge down overnight, primarily to MVFR. Some fog and sprinkles/flurries will also be possible in the east. Bases will slowly lift on Wednesday, through primarily MVFR conditions are anticipated throughout the morning.

GRB WATCHES/WARNINGS/ADVISORIES. NONE.
