Public Analysis: Colder air intrudes this weekend, in a sea of warmth
After coming out of frigid airmass early this week, temperatures gradually moderated to above seasonal levels for mid-week period. This is due to more troughiness over the Western United States, and lack of high-latitude blocking, leading to more progressive pattern with a stronger Southeast ridge.
On the periphery of the ridge, the a more southwesterly flow will has allow for warmer airmass to move into Northeast and Mid-Atlantic region. Meanwhile the storm track has shift well to our north and west due the Southeast ridge. This pattern continue will for the next few days. Another low passing over the Great Lakes will push a warm front with some rain likely through the region tonight. Then temperatures tomorrow could rise well into the 50s or even lower 60s, across the area as even warmer airmass moves into region.
