01/26/2020

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.

A mix of sun and clouds today with a westerly breeze.

01/26/2020

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....

01/17/2020

Skies will be mostly sunny, but it will be much cooler today than it has been recently. Continued gusty winds will keep wind chill values in teens this morning, and 20s/30s this afternoon.

01/17/2020

Snow showers will be streaming off Lake Erie tonight. An isolated snow shower may make it to northern Maryland, but no accumulations are expected. Scattered snow showers, and a dusting, possible in the Potomac Highlands. Otherwise, it will be the coldest night in the past week. Wind chills will be in the teens and 20s by dawn.

the thing is that my mom says you'll be fine whenever i bring up about getting a stomach ache due to eating tons of french fries! Im yelling at you guys about this! 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.
