Forecast Discussion for Northeast Minnesota and Northwest Wisconsin
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.
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.
