Central US

The Central U.S. will see a mix of dry conditions and scattered showers.

Parts of northern Texas and Oklahoma could experience increasing rain chances as moisture moves eastward.

Some showers may also linger across Arkansas, Illinois and Indiana.

Meanwhile, much of the Midwest and Ohio Valley will remain unusually warm.

High temperatures could reach the 70s and lower 80s, running 10–20 degrees above seasonal averages.

However, light showers remain possible in Missouri, Illinois and Indiana, with isolated activity around Minneapolis, Milwaukee and Chicago.

Although temperatures should be comfortable for outdoor activities, localized rain could still affect evening plans.

Northeast and Mid-Atlantic

The Northeast and Mid-Atlantic are expected to have the most favorable Halloween conditions.

High pressure will keep most areas dry, with no significant rain or snow expected during Saturday evening.

Daytime temperatures should reach the low-to-mid 60s, providing pleasant conditions for outdoor celebrations.

However, temperatures could fall into the 40s after sunset, particularly across New England. Some locations may also experience occasional northwest wind gusts exceeding 20 mph.

A warmer costume or extra jacket will help keep trick-or-treaters comfortable.

While Halloween night should remain mostly quiet, rain and gusty winds could return to parts of the region on Sunday as another storm system approaches.
