San Diego has seen only nine Halloweens with measurable rain since 1850, with the most recent being in 1987, according to the Forecast Center. A Level 2 out of 4 flash flood risk covers central Arizona, including Phoenix on Halloween.
Temperatures will be cooler, especially for those in the higher elevations of the Desert Southwest and Four Corners, which could see an even more pronounced autumnal chill.
Weather will remain unsettled, as rain and thunderstorms are likely across those areas.
Texas and Southern Plains
Parts of the Southern Plains will see days of heavy rain and potential flash flooding beginning Thursday, with rain expected to taper off Halloween morning.
West Texas will see the largest flooding concern heading into the weekend, as tropical moisture from the remnants of Vance funnels into the region.

Repeated rounds of showers and thunderstorms could bring widespread rainfall totals of 1 to 2 inches, with higher amounts up to 3 inches where storms repeatedly move over the same areas, the FOX Forecast Center said.
By Friday, the rain shifts farther east into the Plains and Midwest. While mostly light rain at this point, some heavy rain could be possible. Generally wet conditions into Saturday are likely to disrupt some outdoor Halloween plans.
Temperatures will be 10 to 20 degrees above average, in the 70s.
Midwest
Light showers are possible on Halloween across parts of Missouri, Illinois and Indiana. Minneapolis, Milwaukee and Chicago could also see spotty showers.
Unseasonably warm weather will continue across the Midwest and Ohio Valley into early November, with little sign of a sustained cooldown.

Meanwhile, temperatures are expected to run 10-20 degrees above average across much of the Midwest, with highs in the 70s and lower 80s in areas that typically see temperatures in the 50s this time of year.
In Indianapolis, there have been 25 days of 70° or greater. The record in the capital city is 27 and if the forecast holds, they will likely break or tie that record on Halloween.
