A great example of gravity wave clouds is visible on satellite this morning over the region. These are caused by air being forced upward over a barrier (the Allegheny Front in this case) in a stable environment. Fairly common to see in our area.

Winter Weather

Temps well below freezing Sat A.M. will allow for smaller amounts of snow & freezing rain to have higher impact. Travel may be disrupted. Untreated roads/sidewalks may be icy. Watch the first steps out of your home, when many falls occur. Updates: https://www.weather.gov/lwx/winter

This map depicts a reasonable lower-end snowfall amount for the time period shown on the graphic, based on many computer model simulations of possible snowfall totals. This lower amount is an unlikely scenario with a 9 in 10, or 90% chance that more snow will fall, and only a 1 in 10, or 10% chance....

Would you please tell her to stop saying thats fine if I did get a stomach ache! Would you please tell her to stop saying thats fine! Would you please tell her to stop saying thats fine!
The current forecast indicated "short-term drought conditions" ?? We have not had any significant rainfall since mid-June 2019 I!!! The conditions here in Central Maryland are presenting a severe and chronic drought many bushes and plants, and even small trees are dying and blowing away ! When are we going to get some significant rain to salvage the bushes, trees and grass ? This is a long=term, severe drought, imo, and policy measures need to be taken to conserve water and maintain an adequate water supply. It seems probably that climate change is impacting this situation and I want to know what the NWS plans are to deal with this crisis. Thank you. Columbia, MD
Torrential rain in Germantown causing quite a bit of urban runoff. The brown is all the mud being washed away.
