Have the green thumb? You will want to protect the sensitive plants from the cold as the first frost of the season is expected this week. Generally dry conditions in the extended forecast. Hardly a heavy rain event in sight even through the upcoming weekend. Perfect for fall riding.
Frosty Mornings The only sensible weather in the short term will be the concern for frost the next few nights. Early October is typically when we see the first 32 degree low temperature. 'Tis the season.
Water on Mars Big announcement from NASA this week. Scientists announced 'definitive' liquid water exists on the Martian surface. The dark, narrow lines are from liquid saltwater that appear during the warm season, and quickly fade thereafter.
Don't Sweat the Small Stuff If you're ever feeling overwhelmed take a look at this live feed looking down on Earth from the International Space Station. It certainly does put things into perspective.
Summer hangs on strong as temperatures by Sunday approach 80 degrees. If anybody asks, the record high for Sunday is 88 set in 1987. A cool down next week will remind us that it's Autumn but more warmth awaits into early October.
Light showers may disrupt any trail maintenance but overall weather remains quiet and good for riding. Long range temperature outlook highlights a good probability of above normal temperatures into the first few days of October.
A rare supermoon lunar eclipse will occur this Sunday. The full "harvest" moon will make it's closest approach to Earth at the same time being eclipsed by Earth's shadow resulting in a blood red moon. Last time an event like this occurred was 1982, the next time? Not until 2033.
The video below shows why it's important to wear your seat belt during a tornado. Interesting to note the car that cut off the driver with the dashcam was swept away while the lady on the ground seems to be okay.
September 2015 will likely end ~10 degrees warmer than average. Odds favor more warmth (80s?) into the end of the month. Heavy rain event midweek but the weekend looks awesome. Saturday and Sunday will feel like something straight out of mid-August.
That rolling ball of water vapor over California, Arizona, and New Mexico is the remains of a tropical depression that will give Minnesota a good soaking midweek.
The tropical moisture begins to lift north and pool along a warm front over Minnesota. This will result in widespread rainfall amounts topping 1 inch through Thursday.
Early Season Snow:
Tropical downpours in September? No problem. I'll take that considering we could see accumulating snow in September! The most snow ever received in the Twin Cities in September was 1.7" in 1942. The most ever in the state? 16.7" in Milaca in 1905. Yikes.
Record rain of 2.34" fell in the Twin Cities on Thursday. The trails will need time to dry out. Luckily comfortable sunshine returns into next week.
Our meteorological summer (June-August) was nothing short of stellar for mountain biking in the Twin Cities. The MN DNR ranked the summer of 2015 the 3rd nicest behind the summer of 1922 & 2008.
An extra month of summer may indeed be the case this year. Models are hinting at 80s popping back up later this month.
The monthly average temperature has so far been trending 5 degrees warmer than average. A warm, southerly breeze this week will keep temperatures above normal and we will likely finish September 2015 ~10 degrees warmer than normal. That's quite rare.
Minnesota Rainfall: While conditions remain rather dry this week, thundershowers should develop Wednesday-Thursday but will likely be more isolated in nature leaving most areas dry. The metro trails will likely received 0.25" or less of rain this week...just enough to settle the dust.
Sun Twisters: Our sun has been known to get a few tornadoes every once in a while. A tornado formed on the surface of the sun back in 2011 that was 5 times the size of Earth! And now the latest twister observed September 1-3 lasted for 40 hours!
By this time of the year, daylight gets noticeably shorter and the sun angle a little lower in the sky. Cold fronts become stronger as the north to south temperature gradient increases across the country. Cooler this weekend followed by a warm up into next week. We're back into the 80s by Tuesday.
Fall Color. Some trees are already showing their fall colors. Peak of fall color typically occurs between late September into mid October in the Twin Cities metro.
Winter 2015-2016 Predictions. El Nino: bringing weather and climate together. Forecasting the weather for the upcoming winter season is a tricky venture. But the presence of an El Nino event could push the scale toward slightly warmer and wetter conditions in Minnesota. Global models are already hinting at that possibility...
Only rain threat this week will come Wednesday night. Highs in the 60s on Friday may warrant that extra layer. This weekend will be great for cycling: sunny and 70s!
Rain Outlook: Trail conditions should remain good with very little rain through next week. Showers Wednesday night may produce up to a half inch across our metro trails. Drier air should help increase evaporation rates. Next shot of rain comes Monday night next week.
Sometimes good weather doesn't always coincide with the holidays. Trail riding might come to a temporary halt as thunderstorms develop Saturday into Sunday. Don't expect an all day rain but it won't take much to close the trails after a heavy downpour.
Our hot and humid days are numbered as well. Cooler air (highs in the 60s?) arrives next week behind a vigorous cold front Sunday night. Might start to feel like September soon enough!
Summer brings warm afternoons perfect for biking, but the summer heat and humidity can also spark thunderstorms and severe weather. Be prepared for any type of adverse weather headed your way with Aeris Pulse.
