Severe Weather: Feb. 9

A low pressure system is currently located over western Nebraska, and should move east-northeast into northern Nebraska by this afternoon. A warm front is currently located from this low and stretches east/southeast across eastern Nebraska, extreme southwest Iowa and into northern Missouri. This warm front should continue to lift north today, bringing increased moisture and a little warming. This combination may yield some instability, mainly in the lower levels, thus creating a situation in which low-topped supercells are a possibility. With strong vorticity maximum working over this same area, and wind speeds being favorable both in speed and direction, rotating storms capable of a few tornadoes are possible. Strong wind gusts are also likely with these storms, especially any that become mainly linear in nature. Some moderate sized hailstones may be possible as well given the cold temperatures aloft throughout the entire state...

Currently the best area that may see these severe thunderstorms capable of damaging winds, moderate hail, and a tornado or two appear to be over southwest Iowa and nearby locations. A line of showers and possibly a thunderstorm will move through southwest Iowa and into other parts of the state this morning, and over eastern Iowa later this afternoon. Behind this line, some clearing may occur which will increase the risk of severe weather for this afternoon. A close eye will be kept on how this clearing evolves, and any changes in the risks for severe weather across Iowa...

Sorry for the bland view, but I haven't completed all of the things I needed to yet beings I didn't expect to be seeing severe weather in February.

Short updates possible until mid-afternoon, next extensive updates expected by 4 PM.
