Weekly Highlights October 12th to 18th

As we move into the heart of October, this week’s weather is shaping up to be active across much of the U.S., with a strong contrast between stormy conditions in the West and cooler, calmer air settling into the East. From mountain snow to coastal storms, here’s what to expect in the days ahead.

California will see the first signs of change Monday into Tuesday as a weather system moves in from the Pacific. This front will bring rain to parts of the state—welcome news for some drought-stricken areas in Southern California. The Four Corner States—Arizona, New Mexico, Utah, and Colorado—will start the week on a wet note. Showers and thunderstorms will continue to develop thanks to the remnants of what was once Tropical Storm Priscilla in the Pacific. This moisture-laden system could bring heavy downpours and localized flooding. The Plains and parts of the Midwest will also see some chances for showers and thunderstorms this week.

On the other side of the country, a lingering coastal storm continues to batter the Carolinas and the Northeast coastline. Rain and gusty winds will persist early in the week, keeping conditions unsettled along the I-95 corridor and possibly leading to minor coastal flooding and rough surf conditions. Meanwhile, inland parts of the Northeast will experience a distinctly autumnal feel, with more chances for frost and even freezes in the higher elevations and rural valleys as nighttime temperatures drop. Back in the West, colder air in the higher elevations of the Northern Rockies and Sierra Nevada’s could lead to snowfall this week. Early season snow will mainly be confined to the higher mountain passes but is a sign that winter isn’t far behind. Travelers and outdoor enthusiasts in these areas should be prepared for changing conditions.

Overall, the pattern this week is defined by storms out West, a cooler stretch for the East, and lingering warmth in the South. Whether you’re watching for frost or dodging downpours, fall is clearly making its presence known across the country.
