Highs today reached 51-58.
Rainfall varied from trace to +1" last night to today.
Some showers still continue in our far southeast as of 3:30 p.m.
Those will exit & we will see partly to mostly cloudy skies tonight with a northeast wind 10-20 mph & lows 33-39.

Saturday looks windy & mostly sunny, then becoming partly cloudy with highs 57-63. South-southeast to south winds may gust to 35 mph.
With partly to mostly cloudy skies, lows will only drop to 42-47 Sunday night. Halloween evening looks fine, just windy with temperatures in the 50s.
Sunday looks partly to mostly cloudy (north may be cloudy much of the day with stratocumulus/stratus wrapping in from the northwest) behind clipper & strong, but dry cold front.
Highs of 43-49 are likely with northwest winds gusting to 40 mph. So, we will blow down considerable fall foliage Saturday & Sunday, pushing us past peak threshold.
It looks as if Sunday night will be the coldest night of the Fall so far with 25-28 for lows with widespread frost.

As La Nina rapidly strengthens, it only increases the current winter forecast confidence.
1. Wetter than normal here, especially late winter & into spring.
2. Higher risk of flooding winter (especially late winter) & into spring.
3. Higher risk of cool-season severe weather events winter through spring.
4. Most active severe weather winter-spring since 2010-12 period likely.
5. Higher risk of tornadoes in the spring.
6. Higher risk of flash drought & derecho next summer. May end up hotter than this past summer, which would surpass 2012 overall & equal the 1995 & 1999 summer, which were La Ninas. Good La Nina to derecho correlation in the warm season (Serial) & colder season (Progressive).
7. Higher risk of extreme heat/humidity event like 1995, 1999 with upper 90s to 100s & 80s dew points (+115 heat indices) in an instance or two in July or August.
8. Below the normal snowfall of 17-33" for the area (southwest to northeast). Forecasting 9-24".
9. Earlier spring arrival of warmth expected.
10. Earlier budding of trees & plants expected.
11. Significant planting delays possible or a highly split season with part of the crop put out in late April & the in a race around the start of June.
12. Brutally cold, snowy winter in the NW U.S., Northern Rockies, Northern Plains & western Great Lakes.
13. High avalanche danger in the Cascades & Northern Rockies with historic snowfall possible.
14. Dry, drought weather California to Texas, through the Deep South, through Florida to the Carolinas.
15. Much higher wildfire danger in Texas & Florida this winter to early spring.
16. Much earlier wildfire danger in California in 2021.
17. Massive drops in reservoir levels in California with much higher risk of floods in the Pacific Northwest, along with snow risk to sea level.
18. Another very active hurricane season next year.
Every year is different, but the players on the court of importance include:
1. Traditional La Nina - main player on the team
2. MJO - second main player on the team
3. The Atlantic Horseshoe - third biggest influencer
4. Overall PNA, PDO pattern in the Pacific & western Atlantic - fourth
5. Greeland ice configuration - fifth
6. The bench - Solar uptick, New Zealand Dipole
