Snowstorm Feb 26

Image
A fast moving winter storm affected northeast Wisconsin during the day and evening of Feb 26, 2009. Here at OSNW3, conditions wavered between heavy snow and heavy sleet for most of the duration. The last two hours or so it turn to all snow. Highlights of the storm were the rate at which the snow/sleet fell (video below), the size of the sleet balls (video below), and the fact that my roof leaked for the very first time since we've lived here. Thick snow/sleet jams in the gutters were most likely to blame, but I haven't had time to investigate yet.

In my humble opinion, I believe the National Weather Service in Green Bay nailed this forecast. From their interpretations of what was to be expected, what went down still surprised me in many ways.

Winter's Return

Image
It was an active week to our most recent standards. Roller coaster temperatures and two bouts with snow. Enough to bring our monthly snowfall total over the average. My wife Alicia joined in the action as she held down the obs over the weekend when the majority of the snow fell on Saturday, Feb 21. Thanks Alicia!

Record Warmth

Image
This past week harbored six more days with above freezing max temperatures. Making it eight total days, in a row, that temperatures rose above the 32° mark. February broke an OSNW3 daily max temperature record during the day on Feb 10. Precipitation was light this week, but we did see little over an inch of snow fall during the overnight on Feb 13 and 14. Looking forward to Winters return this up coming week. Keep an eye on the forecast by visiting blogs by Derek, Dirk (Northwest WI) and Scout (Southeast WI).

Our first snowfall since Feb 3! The forecast for the overnight on Feb 13-14 called for a 30% chance of snow. To my happiness they were way off. Seeing sn…

Invasive Warmth

Image
It's been over a month since I've felt 40° plus temperatures. Seems I had forgotten how nice it actually feels. As much as I hated to watch the snow melt, I celebrated by being outdoors without feeling that chill on my skin. This warm spell doesn't surprise me. I mean, with the sub zero temperatures earlier this season there is absolutely no reason why we couldn't experience the same thing on the opposite scale. I welcome the change as it will introduce some actual weather into our daily routines. As you would expect, temperatures roller coastered this past week, topping out at 45.9° on Feb 7 while bottoming out at 0.3° on Feb 4. We saw one day of precipitation. Snow fell on Feb 3 to the tune of a whopping 0.3".

Weatherperson's Day 2009

I'd like to personally thank all who choose to take the time to publish their weather info, obs, and data I get to analyze each day! ROKK!

Thursday, February 5 is National Weatherperson's Day, commemorating the birth of John Jeffries in 1744. Jeffries, one of America's first weather observers, began taking daily weather observations in Boston in 1774 and he took the first balloon observation in 1784. This is a day to recognize the men and women who collectively provide Americans with the best weather, water, and climate forecasts and warning services of any nation...

Please read more here... from the NWS in Medford, OR.

Happy Weatherperson's Day!
