A more typical late October air mass is finally bringing widespread frosty conditions to Minnesota.

The mercury bottomed out at 33 degrees at MSP Airport Friday morning. That’s the coldest temperature so far this fall season. Clearing skies and light winds give us a repeat performance Saturday morning. Lows will be in the upper 20s across most of Minnesota, with low 30s favoring the south and Twin Cities areas.

Saturday and Sunday’s temperature maps look very similar. Highs will struggle to reach 50 degrees in the Twin Cities and southern Minnesota, with widespread highs in the 40s. Saturday will be the sunnier day of the weekend.

Rain chance Sunday

A weather system passing south of Minnesota Sunday will bring rain to Iowa and southern Minnesota. The latest forecast model runs suggest most of the rain will stay south of the Twin Cities, but it could be close Sunday. NOAA’s GFS model paints the rain zone.

The early outlook for Halloween still suggests mostly 40s and 50s across Minnesota. Most forecast models are dry for Halloween, but NOAA’s GFS model hints at a chance for light rain, and maybe a few snowflakes.

Stay tuned.
