An active weather pattern is expected to end October, which may impact Halloween plans in portions of the United States.

The main instigator for stormy weather on Halloween will be a cold front stretching from the eastern Great Lakes southwestward into the south-central states.

Along this front will be scattered showers and thunderstorms that could dampen your trick-or-treating plans. The highest chance of wet weather will exist in a swath from eastern Texas to the lower Mississippi and Ohio valleys. A few showers are also possible in the interior Northeast.

Forecast guidance is suggesting we could see strong to severe thunderstorms and heavy rainfall from eastern Texas into the lower Mississippi Valley Wednesday into Wednesday night. This could potentially include Houston and Shreveport, Louisiana.

Elsewhere, a few rain and snow showers may also dampen plans in parts of the Northwest and the northern Rockies on Halloween.

Temperatures on Halloween are forecast to be slightly above average in the East ahead of the cold front. Colder-than-average temperatures will develop behind the front in the southern Rockies and southern High Plains.

Closer to trick-or-treating time, temperatures in the 30s and 40s are likely for much of the upper Midwest, as well as in the northern and central Plains. Areas from the mid-Mississippi Valley into the southern Great Lakes and Ohio Valley will be warmer with temperatures in the 50s and 60s Wednesday evening.

The Northeast can expect temperatures in the 40s and 50s, and areas from the mid-Atlantic into the Southeast and southern Plains can expect temperatures generally in the 60s and 70s.

In the West, temperatures will be in the 60s for much of the California coast, with 50s in the Pacific Northwest. Temperatures in the higher elevations of the West will dip into the 30s and 40s as the sun sets.
