Discussion
The pattern shift that began after the passage of Hurricane Michael late last week looks like it is going to result in numerous cold air outbreaks into the eastern US during the second half of October. After a milder start to the new work week on Monday, it’ll be noticeably cooler today following the passage of a cold frontal system. Another strong cold front will arrive late tomorrow with strong winds and temperatures could bottom out in the upper 30’s in some spots by early Thursday morning for the first time this season and there can be some frost in the normally coldest suburban locations. Unseasonable cold will grip the Mid-Atlantic region on Thursday as highs struggle to reach the 50's (normal high is now 69 degrees). Yet another cold shot will arrive for the second half of the weekend and Sunday will have a feel of winter to it in parts of the Northeast US; especially, in the higher elevations where there can be a touch of snow in the first Great Lakes snow event. Widespread frost is possible around here late Sunday night/early Monday morning.
