Showers Likely Tuesday Night…Drying Out Mid-Week

A frontal zone draped across the immediate South Coast of New England Tuesday morning – marking the dividing line between chilly, damp air to the north and warm and muggy conditions to the south – will inch northward through the day today and pass over the Cape this afternoon. At the same time, a wave of low pressure, accompanied by numerous showers and thunderstorms, will ride eastward out of the Eastern Great Lakes and across New England tonight, passing to our north and east on Wednesday.

This wave of low pressure will drag a cold front across the area on Wednesday morning, with high pressure building into the region thereafter.

The combination of the advancing low pressure center and the quasi-stationary frontal zone sitting over the region will yield a mostly gray and somewhat unsettled look and feel to our Tuesday. Cool morning conditions and pockets of mist and drizzle will give way to somewhat drier conditions during the afternoon as easterly winds switch to the south. However the threat for wet weather will increase again tonight as showers associated with low pressure move into the area.

In between the morning’s damp conditions and the likelihood for showers tonight, we should manage to sneak in some brighter skies during Tuesday afternoon as the aforementioned frontal zone passes north of the Cape. If we’re lucky, we’ll see some holes in the overcast for a time today, which will help shift temperatures back to near 70F for a high.
