Over the very wet soils from the "Beta" rainfall south of our area, thick fog & low cloud deck developed overnight has expanded northward, leading to very low overcast over the area this morning (though there is a band of sunny skies from Pulaski & Fulton to Cass & Howard counties). Low overcast has been pulled northeastward in the strong low-level flow from the south & south-southwest.
Temperatures vary from 62-71 depending on whether you are overcast or in that sunny band. I have 66 here at our WLFI ob site, while the Purdue Airport sits at 66.
Low stratus should erode midday-early afternoon & mix out to just some scattered clouds with south-southwest winds increasing to 20-40 mph. High should around 80 to the 80s. I trimmed highs from 84-88 to 81-86 on account of the low stratus clouds lingering through morning, cutting warming.
After 60s tonight, partly to mostly cloudy skies Sunday with 80s are likely with south-southwest winds 20-35 mph.
A few showers & isolated storms are possible in the evening with the cold front, followed by a band of showers & isolated thunder overnight to Monday morning.
Clearing will then occur Monday afternoon with cooler highs of 65-73 (with west to northwest wind) after 50s in the morning.
Rainfall totals of 0.20-0.45" are likely.
Spotty showers & t'showers are possible Tuesday PM & again Wednesday as upper low to the north spins a few shortwaves southward.
Rainfall totals for Tuesday-Thursday for the area are expected to run trace-0.25".
Skies will be partly to mostly cloudy with strong northwest winds & highs in the 60s with lows in the 40s.
A few isolated showers are possible Thursday with 58-66 for highs & strong northwest winds.
Friday looks dry with partly cloudy, then mostly sunny skies & highs 58-65, followed by 34-40 Friday night with diminishing winds & patchy frost.
An Alberta Clipper may pass late next Saturday with gusty southwest to west, then northwest winds & just a few/isolated showers with partly to mostly cloudy skies. After 34-40 in the morning, highs by late afternoon of 66-72 are possible.
Sunday should feature highs in the 60s with 35-40 possible Sunday night.
Much warmer weather should arrive next week with strong southwest winds.
The October 7-15 will need to be monitored for potential land falling hurricane on the Eastern Gulf Coast to much of the East Coast.
A few showers & storms are possible here around October 8.
Mid to late October & late October to early November looks warmer than normal after some cooler air here behind the hurricane riding up the East Coast.
It also looks continued drier than normal here.
Winter 2020-21 still looks like this with a anomalously cold, snowy winter from the Pacific Northwest, Northern Rockies, Northern Plains & northwestern Great Lakes, while the southeastern half of the U.S. looks warmer than normal.
Winter precipitation anomalies look like this. In fact, every month December-June is trending above normal precipitation-wise.
Snowfall still looks below normal here for the 2020-21 snow season overall.
One thing to note is that even in an overall milder winter, with so much moisture, all it takes are temperatures to dip to 32 for ice & snow. In the very mild winter of 1997-98, Louisville, Kentucky saw virtually no snow.........except one. That one storm was the heaviest snowstorm on record occurred in February with a heavy, heavy, wet, gloppy snow of 22.4" with temperatures 32-33 over a 3-day period (low pressure occluded & moved backward from the east, resulting in snow just sitting over that northern Kentucky to southeastern Illinois region). So, there are times that you have the opportunity for a heavy snowfall in such wet situations, but such snow seasons as the one ahead show a tendency for below normal snowfall. I am looking for that silver lining for you snow lovers out there!
The thing that will need to be monitored is if the core of the La Nina sea surface temperature cooling shifts farther west in the Equatorial Pacific.
If that occurs, then more of the cold, cold air will move east & southeastward.
