WEATHER BLOG: Clear Skies For Thanksgiving Day

Hello everybody,

Surface high pressure will continue to dominate the pattern in the short term, leaving us dry today, Thanksgiving Day and Friday.

High pressure nearly overhead early this morning leading to clear skies, calm winds and a cool start. However, by late November standards, temps. early this morning are not all that cold….hovering right around normal in many places across the area. High pressure slides off to the east later today and tonight. This promotes a good deal of sun today and we will add several degrees to temps. we had yesterday. Clear and calm again tonight with seasonably chilly low temps.

As high shifts offshore later tonight and tomorrow, our low level wind flow becomes light southeasterly. So, we should see at least some clouds show up tomorrow with some lower and mid level moisture getting trapped under an inversion with warming aloft with rising heights and SW flow aloft. That being said, we don't think it ever totally clouds up as the thicker low cloud deck is probably north east of the WJZ area. Elongated high pressure with an axis from Alabama northeastward to east of Newfoundland controls our weather for one more day on Friday. This will promote the low level flow becoming southerly tomorrow night….giving us our mildest day out ahead of the front with a mix of clouds and sun. The breeze will pick up from the SW in the afternoon as well.....so it will feel more like early or mid October as opposed to late November!

At this point, Friday night looks mainly dry though some rain can arrive very late. The front will stall in the vicinity during the day on Saturday so we will have lingering clouds and periods of rain throughout the day. Rain amounts will be light, generally .1 to .2 inches at most.

It remains cool, cloudy and unsettled on Sunday as the next system to the west pushes moisture eastward that quickly overruns the stalled frontal boundary. As this wave comes eastward, we continue to see on and off rain Sunday into Sunday night. Front stalls to the south over the weekend near DC/northern VA. We turn cooler and drier as high pressure noses into the north and northwest of us behind Saturday morning's FROPA. As we head toward the end of the weekend for Sunday into Sunday night, it turns somewhat more uncertain as moisture from the system across the West and Plains begins to ejects eastward and overrun the boundary to our south.
