Forecast Discussion for Northeast Minnesota and Northwest Wisconsin

Today’s Weather:

A ridge of high pressure averaging 1026 mb was beginning to push off to our north/east late Today.  This high kept our area precipitation free Today with some occasional cloudiness along with some sunshine.  Highs Today ranged from the middle to upper 30s from the Iron Range to the Arrowhead with 40s common for the rest of us.  Winds Today were variable in direction under 15 mph.

Today’s Upper Level Analysis:

Water vapor satellite imagery shows that a northwest flow aloft dominated the Upper Midwest on this last day of October.  An upper low/upper trough covered Central-Eastern Canada, south through the Upper Great Lakes, to the Northeast U.S.

Tonight through Monday Night:

High pressure will be centered to our north/east during this period with dry weather for our local area along with partial cloudiness at times.  Low temperatures Tonight and Monday Night will be in the 20s and 30s, but some teens are possible in the traditional cold spots.  Highs for Monday will be in the 40s to around 50 degrees.  Winds will be out of the south or southwest under 20 mph during this period.

Extended Forecast:

A cold front will push southeast across the Upper Midwest from late Tuesday through early Wednesday, this front combined with a 110+ knot mid/upper level jet stream blasting south/southeast out of the Northern Plains will support the risk for a few hours of rain showers in Northern Minnesota and Northwest Wisconsin from late Tuesday Afternoon through Tuesday Evening.  A breezy southwesterly wind will be in place out ahead of this boundary on Tuesday with wind gusts possibly exceeding 25 mph!  Highs on Tuesday will be in the 40s and 50s.  Winds will swing around to the northwest by Tuesday Night and Wednesday with cold advection developing from mid to late week as a very amplified weather pattern sets up across the U.S. thanks in part to a storm system affecting the Eastern U.S. later this week.  A northerly flow will develop across our area late this week while 850 mb temperatures drop to between -6/-12 degrees C.  Low temperatures Tuesday Night will be mainly in the 30s with high temperatures on Wednesday in the 30s and 40s with lows Wednesday Night in the 20s and 30s.

10/30/10: Saturday’s Weather Report

Issued at 5:10 PM CDT, Saturday, October 30th, 2010

Forecast Discussion for Northeast Minnesota and Northwest Wisconsin

Today’s Weather:

An area of low pressure along with a cold front has pushed south/east out of our local area This Afternoon with high pressure pushing east out of the Northern Plains.  Partly to mostly cloudy skies with high temperatures generally in the 40s were found in our area Today with north, northwest, or east winds around 20 mph or less.

Today’s Upper Level Analysis:

Northwest 500 mb flow prevailed in the Upper Midwest Today in between an upper level low which was nearly stationary in Northeastern Canada and an upper level trough which was pushing east through the Western U.S. per water vapor satellite imagery.

Tonight through Sunday Night:

High pressure of 1020-1024 mb will move into the Upper Midwest through Sunday before it shifts slightly to our north/east for Sunday Night.  Dry weather is expected during this period with partly to mostly cloudy skies Tonight and early Sunday giving way to partly cloudy skies Tomorrow Afternoon and Night.  Low temperatures will be in the 20s and lower 30s Tonight and Tomorrow Night with some teens possible in the typical cold spots.  Highs Tomorrow will be mainly in the 40s, but a few 30s are possible in far Northeast Minnesota.  Winds will be out of the north under 20 mph Tonight and Tomorrow with variable winds under 15 mph Tomorrrow Night.

Extended Forecast:

Early next week continues to look dry for our area with high pressure to our east while a cold front moves southeast into the Upper Midwest on Tuesday.  This boundary will move through our local area sometime Tuesday Afternoon or Evening the way it looks now, for the most part this should be a dry frontal passage, although a few light rain showers can’t be ruled out in Northern Minnesota.  The upper level pattern will amplify from mid to late week as a storm system heads up the East Coast while a northerly flow aloft sets up across the Upper Midwest behind this weather system.  The mildest days should occur Monday and Tuesday with high temperatures in Northern Minnesota and Northwest Wisconsin in the 40s, maybe even some 50s on Tuesday.  Low temps will be mainly in the 30s Monday Night and Tuesday Night.  A cooler pattern is expected to develop between Wednesday and Friday of next week and there could even be a few rain and or snow showers at times next Wednesday or Thursday, but nothing significant is expected at this time.  The exception to this could be along the South Shore of Lake Superior from Bayfield to Ashland to Hurley where some light snow accumulations could develop sometime the middle or end of next week.

Forecast Discussion for Northeast Minnesota and Northwest Wisconsin

Today’s Weather:

Strong high pressure ridge of 1028-1034 mb covered the Northern and Central Plains Today while the historic storm from Tuesday/Wednesday moves into Northeastern Canada.  A tight pressure gradient continued between the sub 1000 mb low in Northeast Canada and the high off to our west/southwest which resulted in another day of brisk northwest winds of 10-25 mph with a few higher gusts.  Very cool temperatures have invaded the Upper Midwest Today on the backside of the storm, highs Today were only in the 30s to around 40 degrees.  Mostly cloudy skies earlier in the day has given way to increasing amounts of sun, especially in western/southwest parts of our area.  Any lingering flurries or sprinkles were confined to the Morning hours.

Today’s Upper Level Analysis:

Northwest flow aloft was in place over the Upper Midwest per water vapor satellite imagery while an upper level trough pushes east through the Great Lakes and Central Canada.

Tonight through Friday Night:

A ridge of high pressure will cover the Plains and Upper Midwest Tonight which combined with decreasing winds and clearing skies will result in a cold fall night.  Low temperatures will drop into the 20s for most areas, but some teens are possible in the traditional cold spots.  Friday and Friday Night will feature partly cloudy skies with winds turning to the southwest on Friday as high pressure shifts off to our south/east.  Winds Friday Night will turn northwest as a weak cold front passes through our area.  High temperatures on Friday should get into the 40s for most areas with lows Friday Night in the 20s and 30s.

Forecast Discussion for Northeast Minnesota and Northwest Wisconsin

Today’s Weather:

Deep low pressure (974 mb) has moved into Central Ontario Province as of 2 PM Today.  Gusty northwest, west, or southwest winds continued across our local area Today with wind speeds of 10-25 mph along with some higher gusts.  Cloudy skies with areas of light rain or snow also occurred in our area Today on the backside of this historic storm.  High temperatures Today were generally in the middle 30s to lower 40s with wind chills dropping into the 20s at times.

Today’s Upper Level Analysis:

Powerful surface and upper level area of low pressure covered Central Canada with an upper level trough over the Upper Midwest Today per water vapor satellite imagery and RUC model analysis…A strong upper level jet stream >120 knots was in place in the Central Plains Today.

Tonight:

Strong low pressure will continue to lift northeast reaching Southern Hudson Bay Canada Overnight.  Expect mostly cloudy skies to continue in our area with some lingering showers/drizzle which will mix with and change to snow at times, any accumulations should remain under an inch.  Low temperatures will be in the 20s and 30s with increasing winds out of the west or northwest at 15 to 30 mph with gusts possibly reaching 40 mph during the night as the 850 mb jet increases once again to between 40-55 knots.
