OSNW3 | OSHKOSH-NORTH

Ending with a week long dry spell, the summer of 2010 was still a deluge for the record books. What seemed like an inevitable feat, August kept OSNW3 out of the top spot for wettest summers of all-time in Oshkosh. Falling just 0.39" short of the 20.80" that fell in 1940 for a second place finish. However, officially, Oshkosh has broken the all-time record recording 0.61" more than the 1940 total at the official COOP site . More on that here and here . This summer also ended up being somewhat warm. The mean temperature for the three months at OSNW3 was 71.55°. Without a maximum temperature above 90° we still finished as the 12th warmest all-time in Oshkosh. OSNW3 recorded 55 days in the 80s and 62 nights in the 60s helping keep the mean temperature elevated. Forecast models are continuing the recent summer trends of warm and wet weather with predictions of above average for both to start the month of September.

The middle part of August saw a welcomed cool down. A string of days recording below normal temps and low dew points made everyone much more comfortable. Unfortunately we were in Brooklyn, NY during this period to enjoy it. However, the daily weather descriptions left by the back-up OSNW3 observers, MarkMartin and Jeff Bollier, made my daydreams of cooler weather come true. I thank you gentlemen! WeatherScout also noticed and documented the great weather pattern. I am certain that this autumn will feel a bit cooler than usual even though the temps will be average due to our extremely hot and humid summer. My acclimation to dew points in the middle sixties is disheartening.

August begins as expected for what the 2010 summer has been known for. Hot, humid, and wet. Things will continue this way for the next week or so until a change in the overall patten takes shape. Slightly below average temperatures are forecast for the period starting Aug 16 thru Aug 24. Above average precipitation will accompany the moderate temps. It is likely OSNW3 will surpass the wettest summer (Jun/Jul/Aug) in Oshkosh history total of 20.80". To date we are second with a total summer precipitation amount of 19.37".

July ends on a dry spell, so to speak. Only 0.20" in the last seven days. The two tenths round out the month completing the wettest July in Oshkosh's history. 11.84" were recorded here at OSNW3. More on the record rain in July from the NWS, here . The 6-10 and 8-14 day forecast calls for more above average temperatures and precipitation. **Addendum : Moister Than Most is a great "top news of the day" entry from the NWS in the Twin Cities. It references the many reasons for the heavy rainfall we have experienced this Summer.

In just ten days OSNW3 has recorded another 5.15" of new rainfall. The amount is more than impressive, it's record breaking ( rankings ). Adding the 5.15" onto the 6.49" recorded during the first fifteen days of July puts us at 11.64" for the month through the 25th. The official precipitation record in Oshkosh for the month of July is 8.40". With a break from it today, Jul 25, temps and dewpoints have continued to be above average keeping things nice and hot around the area. OSNW3 is currently 2° above the official Oshkosh monthly mean for July. Many of the EAA campers are enduring the brunt of the record rainfall and above average temps. I personally hope things dry out and the moist air stays south to help make the fly-in a bit more suitable for being outdoors.

Since Jul 5, OSNW3 has recorded 6.72" of new rainfall. Back to back six inch months have left the property very soggy with a most pungent smell of rotten in some areas. Most days have been hot and humid with abundant sunshine making all shaded spots very popular. This evening, Jul 18, was the most bearable of the past fourteen I can recall with a mostly cloudy sky. It was still humid, but the sun wasn't beating down. Long range forecasts call for more of the same but with a little less precipitation.

The Oshkosh area and most of our region experienced three rounds of heavy rain and thunderstorms during the 24hr period ending 7am Jul 15, 2010. Many daily records were broken and Oshkosh was no stranger, crushing the old daily record of 1.55" by 2+ inches. Here at OSNW3 we recorded a total of 3.67". This daily value is unofficially ranked 10th all-time in Oshkosh's history for largest 24hr precipitation total.

The first round of rain came around 5pm dumping 1.02", the second round came around 8pm dumping 1.57", and finally the third round came around 12am dumping 1.08".
