First Day Of Autumn! Kicking It Off With Possible Frost In The Forecast.

It will officially be Autumn at 10:49am EDT. Heck yeah! :) And its really starting to feel like it. Believe it or not we are starting to see a few trees start to change colors around the Lafayette area. And we will be talking about some possible patchy frost in the area by as soon as tomorrow / tomorrow night. Yes get out those heavier jackets and grab a cup of hot coffee, Its about to set in.
 
Temperatures have been right around 65* and 70* degrees as our highs over the past few weeks, However today we will see a high around 59* / 60* degrees. With highs this week ranging between 60* and 70* degrees. Lows at night falling into the middle to lower 30s already. Our average high temperature for this time of year is around 76* degrees, Our average low is around 56* degrees, You can see how fast fall is coming and how below average we are going to be this week. We are already looking into the first actual freeze dates, The national weather service has already released the freeze charts for the Midwest. Take a look below.
This chart above is showing the likely dates for our first freeze at 32* degrees. We are currently expected between October 1st and 10th.
 
Below is the expected freeze dates at 28* degrees.
You can see we are expected between October 11th and 20th.
 
The reason we are seeing these cooler temperatures right now is because of this big dip in the jet stream. Allowing all that cooler polar air to fall into the Midwest.
This map is looking into Sunday at 8:am EDT. Cool temperatures as that jet stream dip is right over the Midwest, Highest expected temperature all week is forecast to be around 70* degrees, Still around 6* degrees below average for this time of year.
 
Now we could very well see some light patchy frost as we head into Sunday night / early Monday morning with temperatures falling into the lower 30s around 35* degrees. Light winds and a dew point around 38* degrees means some light patchy fog is also likely for both tonight and Sunday night. So we will keep a watchful eye on that as well.
 
Your forecast for today and Sunday.
 
Today expect a high around 59* degrees with winds between 10 and 15mph gusting to 20mph possible, Partly cloudy to sunny skies and a cool low tonight around 39* degrees.
 
Sunday a high around 61* degrees with a low that night of 35* degrees, Winds light between 5 and 10mph with sunny skies through out the day, Some early morning light patchy fog is possible. With some light patchy frost / fog later Sunday night into early Monday morning not out of the question.
 
Tonight will be a great night to head out to exploration acres with cool crisp temperatures. Its a great way to kick off the first day of Autumn! I will be out there with my Girlfriend, Sister, and Best Friend having a great time!
 
Take care bloggers, And God Bless.
