Getting Nicer Friday. Balmy Fall Weekend Ahead

Getting Better - Balmy Weekend - Cooler Next Week
By Paul Douglas

You do realize we could be slipping and sliding on snow right now? Accumulating flakes are mercifully rare in late September, but theoretically possible. On September 24, 1985 half an inch of snow delighted Twin Cities commuters. I was standing in KARE-11's Backyard; I remember the collective gasp. "How is this possible?" Well, the sun is as high in the sky as it was in mid-March; longer nights are brewing colder airmasses over Canada which can dribble south.

A strong El Nino should, in theory, trigger more storms for California, and a more zonal, west to east steering wind, pumping milder Pacific air into Minnesota. Odds favor fewer jaw-dropping arctic outbreaks than usual. But we will see cold fronts. That I can predict with rare 100% accuracy.

A shot of cooler air arrives next week but no prolonged chill is shaping up - yet. The sun peeks out Friday; upper 70s Saturday, maybe low 80s Sunday before an outbreak of sweatshirts by Tuesday. 70s return later next week; a lukewarm start to October.

We have precious little to complain about in the weather department, for a change!

Thursday's Rain
It was a bit soggy on Thursday with much of the rain falling during the early half of the day. However, showers held on for much of the evening across the southern part of the state.

Fall Weather Stats
With Fall officially starting on Wednesday, the National Weather Service made a list of Autumn Weather Stats... see below:

Fall Color Update
According to the MN DNR, fall colors are now finally starting to show in many areas across the state, especially up north, where some areas are already near 50%. While we're like still a few weeks away from some serious peeping, this will be a wonderful weekend to get out and find some fall signs.

Minneapolis Temperature Trend
Looking at the temperature trend below, there is anything too eye-opening about the extended forecast other than being mostly warmer than normal. At this point, I don't see any attention getting cold front or major storm systems that we'll have to watch for.


8 to 14 Day Temperature Outlook
It was been a warm September so far with temperatures running nearly 5F to 6F above average in the Twin Cities, St. Cloud and Duluth. According to NOAA's CPC, the 8 to 14 day temperature outlook keeps temperatures quite warm into early October.


Friday Weather Outlook
Temperatures on Friday look to be much warmer than that of Thursday. Highs in the 70s look to be widespread across the entire region with comfortable dewpoints in the upper 50s to near 60F

Friday Weather Outlook
Friday looks like a fairly enjoyable day with gradual clearing, mild temperatures and light winds.

Friday Weather Outlook
After a couple of soggy days Wednesday and Thursday, Friday may be a little slow to clear across the region, but expect more sunshine the second half of the day and more clearing through the evening.


Rainfall Outlook

Any additional rainfall from PM Thursday looks to be fairly light across the extreme southern part of the state. Weather conditions on Friday will be drier and warmer.


National Weather Outlook
Heavy rains that fell from the Southwest to the Midwest over the last few days was thanks to the remnants of Tropical Depression Sixteen in the Eastern Pacific. That rain will fade into Friday, while heavier rains look to develop and continue over parts of the Mid-Atlantic States.

Precipitation Outlook
According to NOAA WPC, heavy rains will really kick in through the Mid-Atlantic states over the next few days with rainfall tallies nearing 4" to 6"+. Localized flooding will be possible over the next couple/few days.


Tropical Basin
Here we are a couple of weeks past the historical peak of the Atlantic Hurricane Season and the tropics are fairly quiet right now... The only storm in the Atlantic is that of Tropical Depression Ida, which has been downgraded from Tropical Storm strength.

Ida Weakens...
This was the remnants of Tropical Storm Ida PM Thursday, which looked pretty disorganized. Note that the brighter clouds (thunderstorms) seem to be blowing east off of the main area of circulation.

Tracking Ida
Although Ida had been downgraded, the forecast calls for additional strengthening by the end of the week/weekend ahead.
