Pattern change is well underway today as much cooler temperatures moved into the Northland after several days of very warm and humid weather. Highs today were much more seasonable compared to previous days which featured temperatures some 15-25 degrees above average! Temperatures this afternoon were generally in the mid 50s to around 60 degrees but the extreme southeast portion of northwest Wisconsin had one more warm day with highs in the 70s to near 80 degrees (Price County, Park Falls area) Skies were mostly cloudy today with some rain showers passing through parts of the area.
Rain is forecast to become more widespread from south to north across the Northland later this evening and through the overnight hours as a wave of low pressure heads northeast out of the central Plains, moving along a cold which is now located to the southeast of our area. Most of the rain that falls later tonight should be light to moderate in intensity although a few heavier downpours can’t be ruled out since PWATS will remain in the 1.30-1.50″ range through the night.
Lows tonight will range from the mid 40s to low 50s in northern Minnesota to the mid 50s and low 60s in eastern Minnesota and northwest Wisconsin.
Rain Tuesday morning will give way to scattered lingering showers during the afternoon hours as low pressure tracks from southwest Wisconsin to eastern Lake Superior while an upper level trough lifts northeast out of the northern Rockies/western High Plains region. Highs Tuesday will range from around 50 to 60 degrees.
Wednesday looks dry with highs in the mid 50s to low 60s.
A few showers or isolated thunderstorms are possible Thursday as a cold front moves through the Northland. Highs Thursday will be in the 60s to around 70 degrees.
