12/24 – Rob Knight’s “Tracking Santa” Christmas Eve Afternoon Forecast
We are on track to quickly warm up into the afternoon hours. High-pressure along the region will shape the forecast through the weekend. Tonight, winds remain a bit breezy in the evening hours which may remain elevated enough overnight to reduce radiational cooling more than previous nights. A Few low clouds around with some thin upper-level cirrus advecting in from the NW.
Christmas day, nothing major changes with the same surface high, now starting to slowly crawl east offshore coastal Florida/north of the Bahamas. Christmas night into Sunday morning, surface dew-points continue to climb a bit higher into the mid-60s, building east as surface flow transitions more from the WSW thanks to the ridge to the east flattening out. Probabilities at this time are higher along and west of I-55, especially across the Atchafalaya basin but wanted to jump ahead of this trend by patchy fog overnight all the way east to the MS coast.
Same story different day on Sunday with another very warm day with the same high bias going with widespread upper 70`s to a few low 80`s with partly cloudy skies.
