WHAT HAS CHANGED

No major changes were needed for this forecast package with generally quiet weather expected over the next few days.

KEY MESSAGES

1. Expect temperatures around or above seasonal averages through the weekend with even warmer temperatures likely through at least midweek.

2. A cold front moves through on Sunday, bringing isolated chances of snow showers. The long term pattern supports active weather next week, with the potential for more widespread precipitation later in the week.

DISCUSSION

KEY MESSAGE 1 DESCRIPTION...

Not much has changed regarding the general pattern over the next several days. Mean troughing will keep temperatures around or just above seasonal categories through the weekend. Today's highs will range from the upper teens and lower 20s north, to the low to mid 30s south. By Sunday, we will see widespread highs in the mid 20s to mid 30s. After some modest ridging moves across the region on Sunday, we transition to several days of mean zonal flow which will allow for another bump up in temperatures. Some lower 40s return to the forecast on Monday with widespread highs in the low to mid 40s possible by midweek.

KEY MESSAGE 2 DESCRIPTION...

An upper-level low over Quebec will move southward during the day Saturday. The low will coincide with a weak shortwave, allowing for the development of some isolated snow showers through the day.

A system looks to move through from west to east towards the end of next week. A lot of model uncertainty remains but appear to have trended a little bit colder than the previous model suite, with all precipitation types still in play. Snow looks more likely across the northern and interior areas, with more rain and mixing possible across southern NH and coastal Maine.

AVIATION /06Z FRIDAY THROUGH TUESDAY/

Generally expect VFR conditions at all terminals through 06z Saturday with a chance for periodic low VFR/MVFR ceilings at HIE. Winds should continue to diminish this morning.

Outlook...

Friday night-Saturday night: Periods of light snow may bring about brief MVFR/IFR conditions Friday night and Saturday night, with HIE and LEB having the highest chance of this occuring. Otherwise, VFR prevails.

Sunday night-Tuesday: Some light snow showers may bring localized brief MVFR/IFR conditions Sunday night into Monday with MVFR ceilings common during this time as well, but otherwise conditions trend back to VFR for Tuesday.

MARINE

Frequent northwesterly gusts around 25kts will continue through the early morning hours today. Winds shift westerly and calm below SCA criteria later in the morning, with seas remaining 1-3ft.

Marginal SCA conditions are possible Saturday night into Sunday as a front crosses the waters. Another system may bring about SCA conditions midweek, but otherwise sub-SCA conditions are expected.
