NOW-THURSDAY (OCTOBER 21-23)………….
Skies are mostly cloudy with brisk northerly to northwesterly winds. A couple isolated showers/sprinkles still cannot be ruled out for this afternoon. After 53-58 today, clearing skies later today with calming winds will lead to frost & 32-35 tonight.
Tomorrow looks mostly sunny & 56-62 with lighter winds, followed by 33-36 tomorrow night.
Clouds will increase Thursday late with 60-65.
THURSDAY NIGHT-SUNDAY (OCTOBER 23/24-26)……………
Clipper will pass Thursday night-Friday morning with a few spotty showers, perhaps an isolated t’shower. Highs Friday of 65-70 look good.
The weekend currently looks great with highs of 68-75 with lows of 44-49. Skies look mostly sunny both days with Saturday featuring much lighter winds than Sunday. Sunday southwest winds may gust to 32 mph in the afternoon.
MONDAY-WEDNESDAY (OCTOBER 27-29)…………..
Monday looks windy & warm with highs of 71-76.
Another Alberta Clipper will pass Tuesday or Wednesday (exact timing is a bit blurry at the moment) with a few showers, perhaps an isolated t’storm or two.
Following this clipper, dry, tranquil, mostly sunny to sunny weather will settle in for right up to Halloween. Highs October 29-31 look to run in the 60s with lows of 37-41. We could see 66-72 on Halloween, per current trends.
The first widespread, soaking rainfall in a while looks to arrive in early November. This looks like a strong, dynamic system with very strong winds at all levels with impressive shear & a good, moist, warm, unstable airmass preceding a strong cold front & upper trough.
Data suggests highs on November 1 could be as high as 75 degrees with strong south to southwest winds up to 35 mph.
If current long-range trends hold, then a severe weather threat could develop from Illinois & Indiana to Arkansas & Mississippi late November 1 through November 2. Dynamics/shear support typical November severe episode with a QLCS squall line. This has the potential to be a widespread 1-2.5″ rainfall.
November 3-4 could see highs only in the 40s with lots of low, gray clouds with overnight lows near 32.
It appears that on the morning of November 4 or 5, with clear skies, a killing freeze could occur with lows of 25-28.
By November 6, southwest winds will return with a warm-up.
60s may return by November 8 (70 in some places?) with approach of what could be another pretty significant weather system of rain & t’storms. After this one, lows of 20-25 could arrive near November 13-15.
