Well, we had some snow today. :(
Here is a picture of the snow pellets on my windshield as I left for class at 7:30am:
Temperature: 32F
Dewpoint: 32F
Humidity: 100%
Pressure: 970mb
Wind: 6 mph ENE
Current surface map from weather.com, as you can see there is an "inverted" trough associated with the low system making its way though. This system is actually a mid latitude cyclone, warm air moves up from the south and mixes with the descending polar air mass creating a "comma" shape cyclone storm. As the wind blows from the North East we will still experience cold temperatures and possibly precipitation.
In this weather.unisys.com image you can see the inverted trough over Minnesota and Wisconsin, descending down through Alabama, causing severe storms along the mid to east coast states.
In this Infrared Satellite image, we can see the tremendous amount of moisture in the air developing due to the instability in the air.
Currently we have an overcast sky, that will continue into the evening and Friday. We may see some clearing by Saturday as the system continues to the east. However we may develop more precipitation by Sunday as another low pressure system develops.
