The blocking pattern continues over the eastern half of the United States. A low pressure system is moving well off to the north of central IL, up in Canada, this weekend. The only change this has on our forecast is some increased high cloud cover at times. The main focus of this forecast continues to be the above normal temperatures and lack of rain.
Temperatures will continue to be above normal as we move into the next week. Highs will be in the low to upper 70s. Normals for this time of year is around 62-66 degrees across central and southeastern IL. The CPC's 6-10 day, 8-14 day, and Week 3-4 outlooks all show above normal temperatures. Dry weather will last through much of the extended period as well.
A weak shortwave passage on Wednesday morning may bring some light sprinkles to central IL but is looking more likely to pass without any activity due to how dry our airmass is. The next best chance for any rain has been pushed off into next weekend, just in time for Halloween. A stronger shortwave appears to pulse through late Friday into Saturday, bringing a 30-50% chance for showers. Amounts are forecast to be pretty minimal, but we are a week out still, so there is time for this forecast to change.
Aviation
