Weather Summary for October 25, 2014
Location: Northeast Minnesota and Northwest Wisconsin
High pressure of 1020mb covered the Northern Plains Today with a strong area of low pressure averaging 990mb over far northeast Ontario. Strong west or northwest winds were the big weather story across the Northland Today with wind speeds of 15 to 25 mph with gusts over 30 mph - these gusty winds were caused by the pressure difference between the low to our northeast and high to our west. Sunshine was abundant in our area Today with high temperatures in the mid 50s to low 60s which is 10-15 degrees cooler compared to Friday, but Today's high temps are still running above average for late October.
Forecast Discussion for Northeast Minnesota and Northwest Wisconsin
Short Term Forecast - Confidence: High.
Tonight (October 25)
Clear skies and cool temperatures can be expected Tonight with lows in the 30s but a few spots might slip into the 20s. Northwest winds at 15 to 25 mph early will decrease to 5 to 15 mph and shift to the south or west during the night.
Tonight's low temperature forecast. 30s for most, but the typical cold spots might dip into the 20s.
Sunday and Sunday Night (October 26)
Dry weather is expected Tomorrow with highs in the 50s except for 40s along the North Shore of Lake Superior. Low pressure and warm front approaching from the west will lead to a chance for showers and a few thunderstorms in the Northland from late Sunday Afternoon but more so for Sunday Night.
A strong low level jet out of the south will develop ahead of this system in Minnesota on Sunday which results in a warm and moist advection pattern, will also see a pretty good push of elevated instability once again - similar to what occurred just a few days ago. MOST UNSTABLE CAPE (MUCAPE) values could approach 500 j/kg in parts of the Northland Sunday Night, so we should see at least a few thunderstorms erupt near or after dark on Sunday. Low temperatures Tomorrow Night will be in the 40s. Winds during this period will be out of the south or east at 10 to 20 mph.
Sunday's high temperature forecast
Extended Forecast - Confidence: High.
