Local View

Note: I've added Thursday forecast due to the long duration of the upcoming system. Due to this systems significance there will be no long term forecast as I keep up to date on the current one. This forecast is subject to changes as we go through the upcoming days.


A Significantly strong weather system is heading towards the area Monday, it will alter our weather for all of the next 4 days. A deepening low pressure system will move from North Dakota to Northern Minnesota, It will drag a very strong cold front with it which will pass through on Tuesday, very high winds are possible ahead and behind this front, wind gusts up to 55MPH are possible. This front will also be the focus for wind driven rain showers, some of this rain could be heavy at times especially Tuesday, we could have over an inch of rain with this system. Wednesday Very strong winds will continue early Wednesday appears when we have the highest winds gusting up to 55MPH, especially early. Much colder air will rush down on these winds, highs Wednesday will likely struggle to reach the low 40s, with wind chills well into the 30s, It will feel very cold and blustery and there will be wind driven rain showers around, Late Wednesday winds will finally start to slow down some. Thursday will be another cold day but not as windy. Some of the left over light rain showers may turn to snow flurries or snow showers. At first it did not look like accumulation was likely, but now it appears some cold air may come soon enough for minor snow accumulations mainly 1 inch or less., Lows Thursday Night will likely fall into the 20s, The coldest air of the season so far is likely with this system!


Very High Wind Potential


Breezy conditions with this system will start as early as Monday afternoon, but As the low pressure approaches and cold front nears, very high W to NNW winds are possible our strongest winds will likely hit on Tuesday or Wednesday morning. Sustained winds of 20-30MPH are possible, with gusts as strong as 55MPH. The local National Weather Service is even warning for wind gust potential to reach as strong as 60MPH with this storm system. Winds this Strong could cause trees to come down, weak deciduous trees, very late turning deciduous trees, and trees with needles such as Spruce or Pine pose the highest risks of breakage. Minor Structural damage is also possible with winds this strong. Communities with open fields and locations in higher areas are highest at risk for 55-60MPH winds, This includes my location. This storm has the potential to bring the strongest winds in a storm system the local area has seen in many years. People in the location area should prepare for very strong winds, take in loose objects and monitor trees closely, a High wind watch is in effect for parts of the area.
