Warmer Ghosts

The average high and low for October 31 is 48 and 29 degrees.  Given that, a rough estimate of an average temperature when most kids are trick or treating would be approximately 40 degrees. Of course with a temperature that cold (or often colder), it is no wonder that designing a costume around hats, mittens and jackets is often a requirement.

But every once in a while we get treated to mild Halloween temperatures.  On four occasions since 1881 the high temperature has reached 70 degrees or higher.   Many of you may still remember the 74 degree high recorded in 1999, or the 72 degree high in 1990.  Although 70 degree Halloweens have been rare, 60 degree or higher days are a bit more common as the high has been in the 60s on 19 occasions.

If everything works out well, Monday in fact, could be our 20th such occurrence and our first in 10 years.  Meaning Halloween 2011 could be the warmest Halloween that most of the kids out tonight have ever experienced.   We will find out on Monday.  But it is looking promising at the moment.

Weather Rhythm

Mark Twain is often given credit for the saying “everyone talks about the weather, but nobody ever does anything about it”.  Although he borrowed the saying from Charles Dudley Warner, his collaborator on The Gilded Age, it was Twain that made it famous.

Another saying from Mark Twain I often use in my public speaking appearances that he may or not have borrowed from someone is “history does not repeat itself, but it does rhyme”.  I doubt he was referencing weather when he said it, but it fits weather patterns quite well.  No two seasons, or years are ever the same, but yet, they will share similar atmospheric and oceanic conditions.  Looking in the past for similar signals to the current pattern can be a very useful tool in projecting future weather trends.

This technique is referred to as the analog method.  Using past analog years lead me to believe this autumn would be mild, which so far has worked well, but the same techniques unfortunately still favor the up coming winter to be colder than average.

The Weather Giveth and Taketh Away

I grew up in the Midwest, yet, after spending nearly 50 years in this region there is one element of Midwestern thought I have never understood.  That would be the concept of somehow we will end up getting punished for our good weather.  I bring this notion up because very frequently in the past few weeks I have read in social media, overheard conversations, or have been personally asked; “I suppose we are going to have a horrible winter as punishment for this nice autumn”.

Too be honest, I rarely have a good comeback for such comments, as of course, the weather does what it does and when you live in this climate, extreme changes should be expected.  But my normal reply is to enjoy the present as the future weather is not here yet and I for one have been taking my own advice and enjoying what has been an almost perfect autumn season.

The Whys of Whats

Weather forecasting can be divided into two categories; why and what.  There is an old joke within the weather community that we are in marketing, not production.  In other words, we try to tell you what is going to happen, but why that weather is going to occur is outside of our control.  Although we obviously cannot control the weather, most, if not all meteorologists spend their time analyzing the why in weather.

Our television and radio audience seems to be divided between the people who only want to know what the weather is going to do and the people who not only want to know what, but also why the weather is going to change.  If you are someone who wants to know the why aspect of weather, time restraints often do not allow always allow us to elaborate as to why certain weather is expected.

But this blog does give us another outlet to explain the daily happenings of our weather and if you ever have a question, please leave a note in the comment section below.

 

Quiet or Busy?

Although another tropical system or two could easily form in the coming days and weeks, the hurricane season in the Atlantic Ocean is beginning to wind down.  If you ask most Americans if it was a busy or quiet season, for the 3rd straight year, most people would say it was a quiet year.  Only one hurricane, Irene struck the coast of the United States this year.  That was the first land falling hurricane in nearly three years ending the longest such stretch since the Civil War.

Another positive factor of the season so far is that no major hurricane (Category 3 or higher) made landfall in the country.  The last time that occurred was Hurricane Wilma back in 2005.  It is these reasons that this hurricane season will likely be remembered as a quiet one, although, by the numbers, 17 storms formed, which is above average.  But with tropical systems it is where they go, rather than the actual number that is far more important.

October in Siberia

Several years ago on this blog, I wrote about the connection between October snow cover in Siberia and winter temperatures in the United States.  Of all the articles I have written, that one seems to be remembered the most as every autumn I tend to get numerous inquires as to what the snow pack in Siberia is this time of year.  October is the month that records the greatest expansion of snow cover in interior Eurasia.  The increase in snow cover in that region is often greater than the entire land area of the lower 48 states.

The theory goes that an early and expansive snow cover in Siberia will affect the pressure and wind flow around the Arctic that allows more frequent intrusions of cold air into the United States.  Through the middle of this month, Siberian snow cover has been less than what was recorded last year, but according to the theory, it is total coverage at the end of the month that matters.

Warm October

The average temperature for the first 15 days of October was 63.0 degrees which was 13 degrees above normal.  That was the warmest first half of October by 2 degrees.  The previous warmest first half of this month occurred back in 1963 when the average temperature was 61.0 degrees.

Although this month so far has been the warmest start on record, just two years ago, the first half of October 2009 was the coldest on record.  That October started off with an average temperature of 39.5 degrees, therefore in the past two years we have experienced the full range of temperatures that this month has bought to the area since 1881.  When added with September, our fall season so far has been the 2nd warmest on record.  Not only has this autumn season been warm, it has also been relatively dry.

The airport has recorded 1.10 inches of rain in the past 6 weeks which ranks this first half of autumn as the 13th driest on record and was the driest such period since 1993.

First Freeze

Although we had an early frost back on September 15, most areas have yet to experience what is generally referred to as a hard freeze.  A hard freeze is considered to be a temperature of 28 degrees or lower. The average date for such an occurrence is October 9.

Last year our first hard freeze occurred on October 17 and this year our first hard freeze will once again occur later than average (perhaps today or tomorrow).  One of the latest freezes on record occurred back in 2008 when the temperature in Fargo Moorhead did not drop to 28 degrees until October 27.   Our first freeze of autumn has occurred in November only five times. The most recent year this occurred was back in 1998, the others occurred in 1940, 1931, 1924 and 1921.  The record was set in 1931 when the first hard freeze held off until November 10.

With the exception of 1924, all those years had very average first frost dates (32 degrees), but the really cold air held off until much later in the season.
