An Indian Summer Looms

Back on Sep 24th we had a surge of moist tropical air work in from the south. Daytime highs topped 80° as the atmosphere rung out an inch plus of precipitation. Even a few rumbles of thunder were heard as the weather worked it's way across the area. On the backside, cooler more seasonal air enveloped the region opening the door for a real autumn bite. Our first frost at OSNW3 wasn't far behind. On Sep 27 the temperature dropped to 39.3° for an overnight low and a light frost developed on rooftops around the property. The Last time the low temperature dipped below 40 was on May 11, 2010 (39.9°). 140 days prior. Since then, frost has become more frequent bringing our tally of frosts to 3. We are still waiting for our first freeze and with all this frost talk it's no wonder we are nearing a forecast that calls for Indian Summer conditions to last throughout the upcoming weekend. A summary for the month of September can be found here.

With my recent upgrade of Image Salsa I am now able to bring to the Internet a daily time-lapse of the OSNW3 webcam. Click here for the time-lapse. Along with that, WIBN6 Suamico-4 NW has a daily time-lapse as well. Click here for the WIBN6 time-lapse.

With an Indian Summer looming, I think I'll have to cut the grass one more time this growing season. And with La Nina being prevalent, I may be cutting in November if we don't get a freeze to halt all growing processes. WxWatcher suggested an annual comparison of the tree across the street. I am obliged. Check back on Oct 8 for a three year comparison of the tree across the street on Oct 7 (2008,2009, & 2010). Fall Color Report is here.

  2. By the way...The time-lapse looks good, it'll be fun to watch that first sticking snow down your way!

  3. Tim, it does feel nice, I will agree. Especially for you as the past week or so Duluth has been quite a bit cooler than Oshkosh. Am I right? Today was the first time the time-lapse file had been uploaded. I didn't get the programing done until later in the evening yesterday, so I am anxious to see what happens come 9am tomorrow. I hope it works out.

  4. We are in a cool down of sorts here though it will be short lived. I cut the lawn again today - 15th time I think. This time lots of leaves from the Crab Apple tree.

    I'm preparing a YouTube Channel primarly with weather related vids. It's in the building phase right now. You inspired me :) plus I'm retired and have time on my hands!

  5. Bob, I liked the photo of the deer eating the crab apples. I am anxious to view your YouTube Channel and I am glad I could help inspire it! Happy uploading...

  6. It has been chilly here in Duluth, you are correct Josh. Most of September was on the chilly side, so it doesn't surprise me too much that October has started out milder than normal. The ying and yang of weather lol.

  7. Tim, after this spell of warmth, I will be ready to start talking snow.

  9. OSNW3,

    We're experiencing an Indian Summer here, too. We have had two mornings with light frost on elevated surfaces, but nothing enough to affect foliage around the house. I even have a 2nd round of cantaloupe that are almost ripe! We've been dry as a bone and I can count the number of clouds we've seen on one hand in the past week. I'm pretty sure you can relate.

    Your picture of the tree across the house looks like our tree situation here. Not much color yet (even though it's still early), and many trees seem to be doing a premature drop. Dry weather and cool overnight temps are supposed to be golden conditions for fall foliage (pun intended), but I think this year it may have come a bit too late. There's still time!

    Bob,

    Can't wait to see the YouTube addition! I appreciate all you guys do.

  10. CJ, I would have to agree. A buddy of mine recently moved back to WI from Northern CA. The past couple days have reminded him of the cloudless warm days out there. This is a wonderful precurser to some late October snow flurries, I hope.

    WxWatcher, we expirenced similar weather in early October of 2007. Which was also a La Nina year. What followed was a parade of snowstorms during DJF. I am holding onto some hope that we may see an elevated snow total this winter. There is plenty of color around the area. The comparison photo shows that 2009 was a more colorful year for the TAS. I think the burning bush in my front yard is about to burst in flames.

  11. I've got to agree with Tim; it feels great to see "Indian Summer" in text again.

    It's just beginning to look like fall down here. We have a couple trees on the street that look absolutely stunning.

    The temperatures are feeling great.
    Chris
