Here it comes – #ActualFall! How chilly will it get?

We’re almost there!

This recent run of hot weather, while not record-breaking by official measures, certainly has been unwelcome! Our typical last 90-degree day for the summer is September 23. Seems we’ve blown right past that! I fully expect that today was the last day of 90 degrees for 2023. Fortunately, typical summertime humidity levels have not accompanied the recent heat wave, which has allowed morning and late evenings to be somewhat comfortable. But I know what just about everyone is looking forward to now!

Here comes our first “pumpkin spice latte” front! 

The surface weather map for Friday morning shows a cold front moving through the Mid-South with high pressure dropping out of the Canadian Rockies, which will build into the region this weekend!
While the “real” cold front won’t arrive until Friday morning, a trough of low pressure will move into the area Thursday. Preceding that feature, cloud cover on Wednesday will keep temps in the mid 80s, then the trough brings our first decent chance of rain in a couple of weeks on Thursday. The clouds and showers will result in temperatures in the 70s on Thursday, but with pretty humid air as well. 
Fortunately, severe weather parameters are meager and we may not even hear any thunder. Rain amounts won’t be enough to put a dent in ongoing drought conditions, perhaps only producing a half inch or so of precipitation. Areas to our west in AR will get some much-needed rainfall, as well as thunderstorms ahead of the front. 

As the big front arrives Friday morning, it’ll push any leftover rain chances to our east and cool air of Canadian origin rushes in for the weekend, resulting in the coolest days we’ve experienced since late April, and sunny skies! Get those sweatshirts, sweaters, and long pants out, as we’ll be waking up to temperatures in the 40s to near 50 Saturday. Sunday and Monday mornings! Highs will stay in the 60s this weekend before rebounding back into the 70s next week.
