PM Update: Chilly evening on the way

Pleasant weather had gripped the area over the last few days, until clouds moved in early this morning and showers affected the area until about noon. The dreary and rainy conditions of this morning weren’t a result of a weak or irrelevant disturbance, however. Instead, they were associated with a reinforcing shot of cold air which comes just 5 days after high temperatures reached the upper 90’s in many locations. Temperatures at the 850mb level of the atmosphere can often be a good indication as to where the weather pattern is situated temperature and sensible-weather wise, and this time around is no different. Comparing 850mb temperatures to 5 days ago yields an eye opening change: 850mb temperatures reached 22 C last Wednesday, and will fall to near 2 C overnight tonight.

Behind the reinforcing cool shot from this morning, northwest winds. clearing skies and the aforementioned crisp airmass will allow temperatures to fall into the upper 30’s to lower 40’s in the interior from late Monday night into early Tuesday morning. High temperatures on Tuesday afternoon will likely reach only into the 60’s (and will at least struggle to reach 70 in the warmer locations). A bit of a rebound is expected as the week goes on, with high temperatures slowly climbing into the middle 70’s. This is fairly typical for this time of year – the cold shots only last for a brief period of time in the early meteorological autumn season.

All of that said, a very pleasant work week is on the way. No hazards are expected, weather wise, for the entirety of the week. The chances of rain look very minimal, and there will be plenty of sun and seasonal temperatures through Friday. Enjoy it!
