Area Forecast Discussion National Weather Service Duluth MN 644 AM CDT Thu Jul 29 2021

DISCUSSION. (Today through Wednesday) Issued at 351 AM CDT Thu Jul 29 2021

Summary: Dry and not as warm across the Northland today and Friday with seasonal temperatures. A chance of showers and storms returns Friday night and Saturday. Thereafter temperatures will gradually trend a little warmer, a few degrees above normal.

An upper-level ridge will build eastward across the Northern Plains and Canadian Prairies today with high pressure at the surface and northwest flow in the mid-levels. Temperatures will trend a little cooler with highs in the upper 70s along the international border to the low and mid 80s across our south. Smoke from wildfires in Ontario and Manitoba will be found near the ground and aloft today on northerly winds. An Air Quality Alert remains in effect for portions of northern Minnesota where conditions will be most hazardous. A cool front will sag southward across Ontario and Manitoba on Friday and move into northeast Minnesota Friday evening. A few showers or isolated thunderstorms may percolate along the boundary but instability will be low, with MLCAPE on the order of 500 J/kg. Severe storms are not expected. Temperatures will trend a few degrees warmer across the north and will be similar south ahead of the front Friday with highs in the upper 70s east to middle 80s west. Shower and storm chances persist overnight through Saturday afternoon. Instability and shear will be a little more favorable for storm organization on Saturday. A few storms may be strong south of MN 210 and over most of northwest Wisconsin. Hail of up to penny-size will be the main threat with any storms.

Northerly to northwest flow aloft will persist Sunday through much of the upcoming week. A few shortwave troughs are forecast to ripple across the region and may touch off some afternoon or evening showers. More organized or widespread shower and storm chances return next Thursday with rain chances of 15 to 30 percent.

AVIATION. (For the 12Z TAFS through 12Z Friday morning) Issued at 644 AM CDT Thu Jul 29 2021

Smoke continues to affect the terminals this morning. Visibility trends in smoke and fog have been irregular and difficult to forecast. Think we will continue to see visibility fluctuate between MVFR and IFR until we can mix some of the smoke away from the surface as the boundary layer deepens this morning. HRRR near- surface smoke forecasts suggest the strongest plume of smoke will push south of the terminals by late morning or early afternoon. Winds will be gusty this afternoon and should remain generally from the north. Fog may develop at HYR again tonight.

MARINE. Issued at 351 AM CDT Thu Jul 29 2021

High pressure will be over the region for the next few days with winds 5 to 12 knots. A cool front will move southward over the lake Friday night into Saturday morning and may provide slightly higher northeast winds for a few hours in its wake.
