This will be a very cold week with lows on Wednesday morning ranging from the single numbers to low teens…and not a whole lot warmer on Thursday morning.
Southerly winds will slowly erode the arctic air mass as the weekend approaches, but it will still bottom out in the 20s to start of your Friday.
This large chilly air mass will extend deep into the Gulf, so it will take several days for moisture return to be significant. The models are in fair agreement on the next shot of cold air to arrive either Sunday or Monday. There will be a chance of precipitation with this system.
It remains to be seen whether this will be a rain or snow event, but since the surface air will not be as dry as during last weekend’s snow event, less evaporative cooling is expected. This set-up favors rain over snow. Also, the strong upper support we had last weekend looks to be lacking, further reducing the cooling aloft (discussion continues below map).
The air behind this next front looks to be cold but, not truly arctic in nature. The steering winds are indicated to drive the frigid stuff into the eastern U.S.
It’s a number of days away so feel free to check back for updates as this next system takes shape.
