It's been a very dry September. We've had little to no rain the entire month. Because of this, there is a Drought Monitor in effect right now.
Most of our area is still under abnormally dry conditions this week. And some spots are under a moderate drought right now as well. This Drought Monitor map is issued by the National Drought Mitigation Center. It is updated once a week. This is the current map for the week of September 16th through the 22nd. Most of the area is under the yellow shading, which is abnormally dry conditions. If we zoom into Northern Oneida County, there is a moderate drought in effect. This is for locations such as Boonville, West Leyden, and Mohawk Hill.
These dry conditions have persisted through September. Most of the month had no rainfall. Only six days with a trace to 0.03" of rain. And really only one day with a good soaking rain of 0.8" of rainfall. This makes up nearly 90% of the months total rainfall, which is still under 1.0" right now.
September 2020 could set a record for the top 10 Driest September's. First place comes in at 0.74" recorded in 1974 and the record for tenth place is currently at 1.49" set in 1932.
The reason for this dry stretch of weather is the location of the jet stream. It is much further north than it usually is for this time of year. Weather systems that bring us rain, travel along the jet stream. But this September, they were dragged north before they could reach us. The good news is that next week the jet stream will dip further south bringing some much needed rain. But we look to stay dry for the weekend, then the rain arrives on Monday.
