1/12 – Brittany’s “Colder” Thursday Night Forecast

As the frontal system moves offshore, strong high pressure will dominate the upper level pattern. Strong northerly flow will help to advect cold air and dry air into the region. While it will be windy (10-20mph) tonight through Saturday morning, a wind advisory will not be necessary as conditions are below criteria and impacts are not expected. With clear skies and lighter winds by Saturday morning, radiational cooling will be possible, which is expected to help the low temperatures overachieve vs NBM guidance. As a result, low temperatures were bumped down 2-3 degrees to be more in line with general model consensus and the potential to overachieve guidance. Lows are forecast to be generally in the upper 20s to upper 30s the next few days. High temperatures will be in the 50s and low 60s for most locations.

Sunday through early next week, the high pressure will move off the eastern coast of the US, weakening somewhat starting Sunday. Southerly surface winds will reintroduce moisture into the area starting Sunday. High temperatures will be in the 50s and 60s across the area. Dry weather conditions are expected Sunday as it is mainly a recovery day for the atmosphere.
