Arb Sightings 10/14/10

As our Indian Summer begins to taper off this weekend, temperatures will become more October-like. The forecast for next week shows highs in the mid-50’s to low 60’s, and lows might reach the low 30’s and give us a few frosty mornings here in southern Minnesota. It appears that this current dry spell that only […]

Don’t you just love mid-October? Over the past few years it has been the middle of this month that has varied the most. Two years ago, the weather was temperate in the high 50’s and low 60’s; people were wearing light jackets in the morning and shedding them by the afternoon. Last year, a light […]

The first full week of fall has been rather pleasant. High temperatures have been comfortably in the 60’s and 70’s, and we’ve seen nothing but sun all week. Even the winds have been light to almost nonexistent. Thankfully, it has also been much drier; no rainfall has occurred in southern Minnesota since early Saturday morning […]

It’s rough being a meteorologist in Minnesota. Granted, no meteorologist anywhere in the world has a 100% track record of predicting what the weather is going to do. There is simply too much data extrapolation, probability, and just plain guesswork involved to ever be consistently accurate over a long period of time, at least with […]

This week of cool temperatures has brought more rain to southern Minnesota. In fact, on late Wednesday afternoon 9/15, over 1.5 inches of rain fell in St. Peter in just a few hours. This downpour would have been impressive enough by itself, but the highlight for most of us came during several minutes of hail […]

Perry’s Berries – the Corpse Flower’s Fabulous Fly-Blown Fecundity

Perry the Corpse Flower has surprised us yet again.  I was disappointed with the small amount of pollen that I was able to collect during the July 2010 flowering event, and am now shocked at the apparent self-potency of whatever amount of said pollen was produced. Here’s the story.  I had not checked closely on […]

Just a few weeks ago we were stuck in a rut of sweltering 90-degree heat. This week, high temperatures have struggled to reach the 70’s, and lows on some days have dropped all the way down to the mid-40’s. These cool fronts have brought more rain into southern Minnesota, including 0.89 inches yesterday here in […]

September certainly begins cooler than August, but not  drier. Indeed, the cold front that arrived a few days ago has already brought well over an inch and a half of rain to south-central Minnesota, including about an inch of precipitation late yesterday and early this morning. We might stay dry from now until mid-week of […]

Lower humidity levels and temperatures in the high 70’s and low 80’s have been much appreciated this week. A windy warm-up is forecast for this weekend with highs approaching 90 degrees Fahrenheit,  but thereafter high temperatures should remain in the mid- to upper 70’s and lows should be in the mid- to upper 50’s. Around […]

Arb Sightings 8/18/10

These mid-August days in the 70’s have felt quite refreshing to southern Minnesotans as we return to outdoor activities in comfortable temperatures. Humidity levels however are still rather high, and over the weekend St. Peter received another inch of rain via a couple thunderstorms. According to the next ten days’ forecast, we’re in for another […]
