Good Afternoon!
More seasonable Canadian air is in here now, but we will see a bit of moderation in that, along with some showers and such in the area as we get toward the weekend. Let's take a deeper dive and see what's going on...
FALL IS HERE - NO QUESTIONS ASKED: Troughing and cooler air will work their way across the country over the next few days. Right now the upper air setup is trough west, ridge east, with an upper low over eastern Pennsylvania and lower New England that will eventually give up and move offshore. The trough is kind of resting over the Rockies and High Plains now, but it will soon put it in drive and head east. We'll see temperatures trend up into the 70's tomorrow, and after that, a frontal boundary comes through in time for the weekend that will bring seasonably mild weather and cool nights on the back side of that. But first, we'll see some...
PERIODS OF RAIN AND PERHAPS A FEW STORMS: Forecast data indicates that there will be a chance of a few showers and storms anytime between now and Sunday really, but the best chance appears to be a smaller rain event tomorrow into Friday, with a more substantial risk thereafter. Have a look at this map:
You'll want to keep an umbrella handy, no doubt. I'm curious to see how intense the cold front coming through will be, as there's the chance of a gusty thunderstorm rolling through ahead of the front, after that, you'll want another layer of clothes, because after that front, we'll see...
READINGS DIPPING INTO THE 40'S: Forecast models are indicating that we may not make it out of the 40's on Saturday! Currently the GFS is printing a high of only 48 for Jackson! I'll need another model run (which is processing now) to confirm it, but based on the data at hand, that doesn't look like a lowball prediction to me.
MORE CHANGES TO START THE NEW WEEK: After we get the chilly stuff on Saturday and Sunday gone, the pattern resets again and more west to east flow allows readings to get back comfortably into the the 60's. A surface boundary being dragged behind a bona fide low north of the border touches off more showers on Tuesday, then things look to be fairly quiet thereafter.
Here's the forecast:
Have a wonderful day! Blessings.
