Stagnant Pattern

I just had 0.19" on September 21, so I am at 0.23" for the month. We need another 0.31" to crawl out of last place for September. We may actually get close to that on Tuesday 9/22. The latest storm system is stalling out a little closer to us than earlier anticipated, so our chances of rain have improved!

----------------------------------------------------------

It looks like it could be a long time before we see any pattern change. Northern Minnesota has been underneath a very large upper level ridge of high pressure for the past three weeks. This high has been so strong, in fact, that any storm that tries to approach our area has stalled in the Dakotas, moved back westward, or dissipated completely. Consequently, we are on track to have our driest September on record. The present record stands at 0.54" in 1967, and so far (through September 19), we've only managed 0.04" according to my rain guage. With no rain in the foreseeable future (about 7-10 days), it looks like we will probably blow away the record.

The past month, we've seen only two thirds of an inch, which is near a record level for that time period. Our climate has definitely taken a shift toward more dryness.

The present pattern is one we usually get during moderate to strong El Ninos, so you should get used to this pattern.
