Forecast discussion for routine afternoon forecast issuance

SHORT TERM. Tonight and Friday Issued at 235 PM CDT Thu Jul 29 2021

Nice weather expected tonight through Friday as a surface high moves from southern Canada to southern Wisconsin. Scattered to broken clouds should dissipate this evening after sunset, though there will be some elevated smoke at times. Lows will range form the middle 40s in the far north to the mid 50s near Lake Michigan.

Friday will be mostly sunny and pleasant, with temperatures mostly in the 70s accompanied by low relative humidity. There doesn't seem to be much smoke upstream, so the sky should actually look blue.

LONG TERM. Friday Night Through Thursday Issued at 235 PM CDT Thu Jul 29 2021

The main forecast concern in the extend forecast is the potential for strong to severe thunderstorms Saturday afternoon. Much of the rest of the forecast period is fairly quiet.

Friday night and Saturday: High pressure over southern lower Michigan, will shift to the southeast through early Saturday morning. As this happens, a nearly west to east oriented cold front will sag southward into northeast Wisconsin through the day Saturday. Aloft, northeast Wisconsin will continue to be in northwest flow as the area remains on the inflection point of troughing to the east and upper-level ridging to the west. Cloud cover will increase along the cold front in the morning, near the Upper Michigan border before moving through the rest of the area throughout the day. The cold front is expected to pass through central/east-central WI later in the day, closer to 21Z, which would allow more unstable conditions during peak heating. MUCAPE values are progged to increase to around 1000-2000 J/kg by that time period, with deep-layer shear values around 30-35 kts. This will be enough to allow for isolated to possibly scattered strong to severe thunderstorms Saturday afternoon. Again, the main threat areas appear to be central into east-central Wisconsin. The main severe threat will be gusty winds and hail, with dry air noted in the mid levels. The Storm Prediction Center has portions of northeast Wisconsin in a Marginal Risk of severe storms for Day 3 (Saturday). Otherwise, high temperatures are expected to be in the upper 70s to low 80s. Overnight lows are expected to be in the 50s to around 60.

Saturday night through Sunday: High pressure is expected to build across the area through this time period, bringing dry conditions along with mostly clear skies. Overnight lows are expected to be in the 50s for most locations; however, there could be a few upper 40s in the typical cools spots in north-central WI. High temperatures will be in the 70s.

Rest of the extended: A shortwave is expected to pass through the area Sunday night into Monday and may bring increased cloud cover. Moisture looks to be fairly limited; therefore, kept conditions dry. Otherwise, high pressure will linger nearby through much of the rest of the extended, with an area of low pressure sliding across the northern Plains/south-central Canada Wednesday into Thursday. Otherwise, temperatures are expected to be near normal with less amplified flow across the area. Average highs for this time of year are around the low 80s.

AVIATION. for 18Z TAF Issuance Issued at 1226 PM CDT Thu Jul 29 2021

Expect a mix of VFR/MVFR conditions this afternoon with scattered to broken clouds with bases around 2500 feet. Sites will likely oscillate between SCT and BKN as the clouds move through. Meanwhile, satellite imagery depicting and large area of smoke across MN with a piece stretching into central WI. This smoke may produce a haze at times, but not expect much for surface impacts across NE WI. A couple sites have had visibility drop to 6SM or 7SM from the smoke, but do not expect any visibility drop to last very long at any site; therefore, did not include in 18Z TAF update. Otherwise, north winds will gust to 15 to 20 knots through early this evening then become light overnight. Low clouds will also dissipate this evening with only some passing high clouds or high smoke overnight and into Friday morning.

GRB WATCHES/WARNINGS/ADVISORIES. NONE.
