313 AM EST Mon Jan 19 2026
.SYNOPSIS...
Breezy northwesterly winds will briefly diminish across our local
waters this afternoon before shifting to northerly and then
strengthening overnight tonight and Tuesday morning as Arctic
high pressure builds towards the southeastern states. This high
pressure center will shift towards the Mid-Atlantic coast on
Tuesday evening, resulting in winds shifting to northeasterly on
Tuesday night and Wednesday. Weak coastal troughing developing
over our near shore waters on Wednesday night and Thursday may
develop isolated to widely scattered showers. A weak cold front
will then push southward across our area on Thursday night and
Friday morning, possibly accompanied by a few showers. High
pressure building over the Mid-Atlantic states in the wake of this
frontal passage will maintain northeasterly winds across our
region late this week and into the upcoming weekend.
