DISCUSSION
KEY MESSAGE 1 DESCRIPTION...
High pressure will remain in place through the upcoming week, bringing continued dry weather conditions and near average temperatures. High pressure will drift to our southeast today, allowing for light southeasterly return flow. This onshore flow will limit high temperatures across coastal locations to the 50s while inland areas warm into the lower 60s. Other than some passing high altitude cirrus, it will be a mainly sunny dry day. Tonight will be cool, although not as cold as previous nights with lows falling into the middle to upper 30s in most locations.
A sfc cold front will cross on Tuesday but will bring little fan fare as the dry airmass will prevent any beneficial rainfall. High temperatures will be mainly into the lower 60s with mostly sunny skies prevailing. Tuesday night will feature low temperatures at or below freezing in most locations. Canadian high pressure will build to our north on Wednesday, with mostly sunny skies and highs into the 50s. A stronger cold front will then cross Thursday into Thursday night as a nor'easter moves well offshore to our southeast. A trof will then move in behind this front for Friday with cooler temperatures to follow. Dry weather and near avg temperatures look likely for the upcoming weekend.
AVIATION /02Z MONDAY THROUGH FRIDAY/
Through 06Z Tues: VFR conditions with light and variable flow at night and light S winds of 5-10 kts during the daytime. No LLWS is anticipated.
Tuesday/Tuesday Night: VFR conditions with N winds of 10-15 kts.
Wednesday/Wednesday Night: VFR conditions with NE winds of 10-15 kts.
Thursday-Friday: VFR conditions.
MARINE
High pressure overhead keeps conditions under SCA levels through today. SCA conditions are then likely from tonight through most of the week due to swells from the nor'easter off the coast of the Carolinas. This nor'easter will lift northeast later this week but is expected to remain south and east of the waters. Periods of north to northeast wind gusts above 25 kt are possible Monday night through Wednesday and then again toward late week.
