Discussion

A surge of very warm air will push temperatures to or slightly above the 90 degree mark later today and tomorrow afternoon – perhaps even to record high levels in some spots on Thursday. It’ll stay quite warm on Friday as well with highs well up in the 80’s to end the work week, but there is relief coming this weekend as a classic back door cold front pushes through the region. This front will bring about a low-level wind shift from southwest to northeast – and that would bring much cooler air into the region from the still-chilly waters of the western Atlantic Ocean. Temperatures this weekend are likely to be held in the 70’s for highs on both days. On Monday, a strong cold front is liable to produce showers and thunderstorms up and down the I-95 corridor as it pushes in from the Ohio Valley. Looking elsewhere, while the eastern states experience a surge of very warm air, cold air for this time of year is plunging into the western states and there may actually be a foot or more of snow in Denver later in the week.
