9/12-weatherunderground forecasters discussion.Long term...Thursday night through next Wednesday... the main story is that the medium range models continue to support a pattern shift to much colder weather by midweek and beyond... with potential for early frost/freeze and record to near record cold temperatures. Heres the rest of it-Tue-Wed... aforementioned front looks to usher in much colder air during this period and beyond as large upper trough develops over the central Continental U.S.. medium range models all agree on this pattern shift thus not question of if it will turn colder... rather how much colder. Recent runs of GFS and European model (ecmwf) would support initial cold shot Tuesday into Wednesday with 850 mb temperatures in the single digits to possibly near 0c! This would likely result in near record to record cold temperatures with potential for frost and yes even a freeze in some areas by 12z Wednesday. GFS and European model (ecmwf) both support the typical fall roller coaster on temperatures and indicate moderation into Friday before next disturbance and attendant cold front Ushers in another surge of possibly even colder air for the weekend... just in time for the autumnal equinox. The colder air arriving next week is the main weather story and will be monitoring closely in the coming days. McClure

Bet it won't be as dramatic as that. Barb

Looks like you got some hard frost this morning, Barb? How do your plants do?

Hey Jim I see on the radar that the low has hit Iowa.
Update please...hope your night temps aren't as cold as predicted.

Barb

Sorry I missed this-we had lows of 30F,30F,33F-went from averaging 79/47 first few days of the month to 35/62
the last few days....77F here yesterday(State high)...the dry air really heats up/cools down fast.

Our temps in Sept were -5F on the low and +4F above the average September high....instead of the normal
78F to 52F we had 82F/47F very unusual!

By the way-quite a difference in temps across Iowa,I saw a low of 12F in La Mars Iowa.

Good that you've warmed up again Jim.
That was quite the scare for September.

In ANY month, colder than normal lows and warmer than normal highs is not what we palm lovers have been hoping for.

Here's to a mild winter for us all.

If you drink, don't drive. Don't even putt.

Will be perfect for the palms but the Bananas and other tropicals are not pleased....

5F dewpoint at one point today with 11% humidity.

Maybe dewpoints in the mid 60s tomorrow with 1-2" rain possible.
