It’s the first weekend of Fall!
Huntsville’s weather has been cool even by early Fall standards lately!
The past eight-straight days featured below-average temperatures: 6.3ºF below the seasonal average since last Friday. As cool as that is, it’s actually not outside of what a typical cool spell would be this time of year.
The weekend won’t be quite as cool; in fact, it looks a little like a summer revival ahead of the next big punch of cooler air that arrives next week.
Expect warm, humid days and mild nights. Saturday looks completely dry, but Sunday brings a chance of some low-impact rain.
What’s that mean? Showers that develop Sunday look light and spotty: less than 0.10″ of rain if you get anything at all. Our rain chance (probability of precipitation) is based on the odds of getting at least that much rainfall on a given day. Light rain may be more widespread than you’d think on a 20% kind of day, but the over-all impact is one of little-to-no rainfall.
How’s that BIG cool down looking?
We’ve talked a lot about the forecast for next week looking downright chilly. It still looks that way, and it still looks like there’s at least a chance of the first frost of the season in a few communities that are usually colder than everyone else.
The usual ‘first frost’ for North Alabama and Southern Tennessee is in late October to early November.
Some of our longer-range model guidance has gone crazy with 30s for lows and even some 40s for highs; that seems rather unrealistic from our viewpoint today.
What’s a realistic scenario?
Highs in the 60s and lower 70s and low temperatures as low as 38ºF to 45ºF by next Friday morning.
