-All eyes focused over the Pacific, but especially over the Gulf of Alaska where a powerhouse jet of 130+ knots is slamming into the Pacific Northwest. Lots of energy out that way which will eventually move into the Rockies and Plains from mid-late week. A ‘major’ storm could develop and impact the Upper Midwest and Great Lakes later this week.

Tonight through Monday Night (September 29-30)
Deep low pressure averaging 985mb will remain over Saskatchewan during this period with a cold front over the Northern Plains. A mild SW flow will persist in our area out ahead of the cold front to our west. Expect partly cloudy skies through Monday Night. Low temperatures will be in the 40s and 50s with highs Tomorrow mainly in the 70s. There might be a few showers in far Northern Minnesota Tomorrow Night, but that chance looks pretty low at the moment. Winds during this period will be out of the southwest at 5 to 15 mph with higher gusts possible.
Extended Forecast – Confidence: High.
Tuesday through Thursday (October 1-3)
A cold front will move through the Northland on Tuesday and will then settle south and stall out Wednesday and Thursday as low pressure develops across the Rockies/Plains. Dry weather on Tuesday, and then rain chances return starting on Wednesday, but more so on Thursday the way it looks now. High temperatures will be in the 60s and 70s on Tuesday. 50s and 60s on Wednesday and Thursday with some 40s possible in Northern Minnesota. Lows will mainly be in the 40s Tuesday Night with 40s and a few 50s Wednesday Night.
Long Range Forecast – Confidence: Medium.
Still looking at a potential storm system affecting the Upper Midwest and Great Lakes between the 3rd-5th. Computer models are at odds as to the strength, track, and timing of this potential fall storm so stay tuned to later updates.
Wind and rain will be possible across the Northland on Friday and possibly into Saturday as well (4th-5th) Might get enough cold air to wrap into this storm for a possible rain/snow mix, mainly in far Northern Minnesota and Arrowhead from Friday into Saturday. Could see another rain event or two during the 6th-9th time frame. Near to below average temperatures are forecast through this period.
*7-day precipitation forecast valid thru Sunday, October 6, 2013. A significant amount of precipitation is possible over portions of Minnesota, Wisconsin, and Upper Midwest later this week with perhaps 1-2″+ on the way. (Source, Weather Prediction Center)
