Drought continues to worsen over much of central and western North Dakota with 45% of North Dakota under Extreme (D3) to Exceptional Drought (D4) conditions as of July 25th -- This is up from 40% one week ago.  Note:  Three months ago all of North Dakota was drought-free!

Weather Synopsis

An upper level low with a pocket of -15 C 500mb temperatures has moved into northern Minnesota this afternoon.  The combination of cold temperatures aloft and warmer air near the surface made the atmosphere unstable, and this has resulted in spotty coverage of showers and thunderstorms this afternoon in parts of northern Minnesota with a few other storms popping at times for brief periods in parts of far northwest Wisconsin.  Storms today have been pulsing up and down, they build up, then collapse minutes later, this the result of weak winds in the mid levels of the atmosphere, storms are unable to organize very much.  Brief downpours and some lightning have been the main hazards out of these storms today.  Outside of the spotty convection, skies were partly to mostly cloudy today with highs in the mid 70s to lower 80s with slightly cooler temperatures near Lake Superior due to an easterly breeze.

Isolated showers or thunderstorms will linger across parts of the Northland this evening as the upper level system continues to drop southeast out of northern Minnesota.  Overnight expecting clear to partly cloudy skies with patchy fog.  Lows will be in the 50s to lower 60s.

Pleasant summer weather conditions Friday through Sunday as high pressure covers the upper Midwest and western Great Lakes.  Highs Friday in the 70s and 80s, highs Saturday and Sunday mainly in the 80s.  Note:  It will be a little cooler along the North Shore of Lake Superior the next few days but nothing too chilly thanks to warmer water temperatures in the mid 50s to mid 60s over western Lake Superior.
