5/19/09 Wx Discussion

Well this is going to be dissapointing after all the "good" weather we have been having. (By good weather, I mean thunderstorms). Anyhow, it looks like the pattern has settled down for a while(....sigh).



We are currently under a ridge (500 mb) on both locations, which should lead to relatively sunny weather for some time. The current run of the GFS model, which can forecast out about 10 days, shows little action at 500 mb or the surface. There is really no action until we are about 6 days out on the model (in a realm known as "crystal ball realm." The models generally have trouble with accuracy that far out.). The precipitation that does pop up on the model appear to be a linear thunderstorm. However, models, such as the GFS, generally have trouble with thunderstorm (and you probably don't want the technical reasons).



So, overall, it looks like nice weather in both Alton and DeKalb. I guess we have to deliver the message of nice weather too.



Alton:

Tuesday: Sunny. Hi 77, Low 54.

Wednesday: Sunny. Hi 80, Low 58.



DeKalb:

Tuesday: Sunny. Hi 74, Low 53

Wednesday: Sunny. Hi 78, Low 55
