Although Wednesday started as another day of clouds and drizzle with patchy fog, there are changes in the weather pattern we’ll notice in the days ahead.
The storm in our nation’s mid-section dropping accumulating snow on Chicago will move northeast, with the counter-clockwise flow of air around it pulling a southerly wind up the East Coast, grabbing both warmth and moisture out of the Gulf of Mexico.

Coming off our recent cool and moist weather, we’ll notice the changes, even as subtle as they are: mostly cloudy skies with only glimpses of sun continue but temperatures nudge over 60 degrees on Wednesday afternoon.
The clash of incoming warmth with existing cool will mean scattered showers developing and expanding from south to north Wednesday afternoon and evening, setting up a pattern where we’ll see periodic showers and rain off and on all the way through Friday morning.

The incoming warm air will arrive on an increasing southerly wind with gusts by later Thursday to 40 mph at the South Coast and even a bit higher overnight Thursday night into Friday early morning ahead of a potent incoming cold front that will change the air drastically for the weekend.
Some scattered wind damage is possible Thursday night in the gusty wind, and while there will be breaks between showers so trick-or-treating could certainly go off amidst passing raindrops in many communities, some towns have decided the combination of showers, wet roads and reduced visibility adds a safety concern in addition to simply a classic Halloween ambiance, and have chosen to postpone trick-or-treat festivities.
Regardless, the new air streaming in on a fresh wind Friday will dry the atmosphere for a bright, albeit cool, weekend ahead. In fact, the exclusive First Alert 10-day forecast keeps cool fall air in place all through next week and perhaps even chilly highs only in the 40s by the end of next week.
