Frost Advisory in effect early Thursday morning for parts of west central Upper Michigan (Darker blue area on map) Statement from the National Weather Service http://forecast.weather.gov/wwamap/wwatxtget.php?cwa=mqt&wwa=frost%20advisory
Weather Synopsis
Partly to mostly cloudy skies were found over the Northland today with another day featuring below average high temperatures in the 60s with a few locations reaching 70 degrees. There is a pretty impressive disturbance dropping south/east out of southern Manitoba Province this afternoon — Winds aloft up to 90 knots were found just west/south of the track of this system, and this is providing the necessary lift for an area of rain to sustain itself as it drops southeast out of northwest Minnesota this evening.
A period of rain moving NW-SE affecting portions of the Northland tonight — The bulk of the rain should remain west of a line from Ely to Hurley. The rain will end from NW-SE later this evening/early Thursday morning. Lows tonight in the 40s to around 50 degrees but 30s are likely up north. Note: Areas of fog should develop late tonight, lingering into mid morning Thursday.
Dry on Thursday under partly to mostly sunny skies. Highs will be in the 60s to lower 70s with an easterly wind. Note: There is a chance for patchy frost early Friday morning especially over parts of northern Minnesota (Inland from Lake Superior) as lows dip into the mid 30s, possibly into the low 30s.
The next system to affect us after tonight will occur from Friday through Sunday as a slow moving area of low pressure tracks east/northeast out of the northern Plains. Note: At the moment it looks like the greatest chance for widespread rainfall will begin either Saturday afternoon or Saturday night and continue through Sunday with scattered rain showers possible in parts of the area from Friday afternoon through Saturday morning. Temperatures look cool especially the daytime highs which are forecast to range from the upper 50s to mid 60s Saturday and Sunday.
