DISCUSSION

Pattern Synopsis and Forecast:

There is not much active weather to report for this forecast cycle as a midlevel split flow pattern with a classic high over low blocking set up will keep conditions quiet across the Great Lakes Region the next several days. 500mb ridging with its axis over northern Ontario will support surface high pressure to influence the Northwoods and keep weather mostly sunny and rain-free. H8 temperatures are currently in the single digits and will warm along the dry adiabats this afternoon, keeping highs in the mid-60s for most locations. The only impactful weather to watch for will be continued chilly overnight lows tonight through the end of the week. Efficient radiational cooling overnight with clear skies will lead to minimum temperatures in the upper 30s for most areas. Localized areas and typically colder locations across the CWA (interior and elevated terrain) will produce frost and pockets of temperatures falling into the low 30s. Confidence of frost headlines remains low as frost will likely remain patchy/isolated.

Long range ensembles introduce some low end chances of rainfall as an embedded shortwave develops over the Central Plains and lifts across the Great Lakes Region next week. Again, chances remain low as jet dynamics depict this wave lifting while remaining very moisture starved. Showers will likely dissipate with time as it approaches the CWA, but we will continue to monitor rain potential as this is the first chance of precipitation after several days.
